When nanoparticles collide

The science of collisions, although it looks more like kissing to me, at the nanoscale could lead to some helpful discoveries according to an April 5, 2018 news item on Nanowerk,

Helmets that do a better job of preventing concussions and other brain injuries. Earphones that protect people from damaging noises. Devices that convert “junk” energy from airport runway vibrations into usable power.

New research on the events that occur when tiny specks of matter called nanoparticles smash into each other could one day inform the development of such technologies.

Before getting to the news release proper, here’s a gif released by the university,

An April 4, 2018 University at Buffalo news release (also on EurekAlert) by Charlotte Hsu, which originated the news item, fills in some details,

Using supercomputers, scientists led by the University at Buffalo modeled what happens when two nanoparticles collide in a vacuum. The team ran simulations for nanoparticles with three different surface geometries: those that are largely circular (with smooth exteriors); those with crystal facets; and those that possess sharp edges.

“Our goal was to lay out the forces that control energy transport at the nanoscale,” says study co-author Surajit Sen, PhD, professor of physics in UB’s College of Arts and Sciences. “When you have a tiny particle that’s 10, 20 or 50 atoms across, does it still behave the same way as larger particles, or grains? That’s the guts of the question we asked.”

“The guts of the answer,” Sen adds, “is yes and no.”

“Our research is useful because it builds the foundation for designing materials that either transmit or absorb energy in desired ways,” says first author Yoichi Takato, PhD. Takato, a physicist at AGC Asahi Glass and former postdoctoral scholar at the Okinawa Institute of Science and Technology in Japan, completed much of the study as a doctoral candidate in physics at UB. “For example, you could potentially make an ultrathin material that is energy absorbent. You could imagine that this would be practical for use in helmets and head gear that can help to prevent head and combat injuries.”

The study was published on March 21 in Proceedings of the Royal Society A by Takato, Sen and Michael E. Benson, who completed his portion of the work as an undergraduate physics student at UB. The scientists ran their simulations at the Center for Computational Research, UB’s academic supercomputing facility.

What happens when nanoparticles crash

The new research focused on small nanoparticles — those with diameters of 5 to 15 nanometers. The scientists found that in collisions, particles of this size behave differently depending on their shape.

For example, nanoparticles with crystal facets transfer energy well when they crash into each other, making them an ideal component of materials designed to harvest energy. When it comes to energy transport, these particles adhere to scientific norms that govern macroscopic linear systems — including chains of equal-sized masses with springs in between them — that are visible to the naked eye.

In contrast, nanoparticles that are rounder in shape, with amorphous surfaces, adhere to nonlinear force laws. This, in turn, means they may be especially useful for shock mitigation. When two spherical nanoparticles collide, energy dissipates around the initial point of contact on each one instead of propagating all the way through both. The scientists report that at crash velocities of about 30 meters per second, atoms within each particle shift only near the initial point of contact.

Nanoparticles with sharp edges are less predictable: According to the new study, their behavior varies depending on sharpness of the edges when it comes to transporting energy.
Designing a new generation of materials

“From a very broad perspective, the kind of work we’re doing has very exciting prospects,” Sen says. “It gives engineers fundamental information about nanoparticles that they didn’t have before. If you’re designing a new type of nanoparticle, you can now think about doing it in a way that takes into account what happens when you have very small nanoparticles interacting with each other.”

Though many scientists are working with nanotechnology, the way the tiniest of nanoparticles behave when they crash into each other is largely an open question, Takato says.

“When you’re designing a material, what size do you want the nanoparticle to be? How will you lay out the particles within the material? How compact do you want it to be? Our study can inform these decisions,” Takato says.

The joys of an electronic ‘pill’: Could Canadian Olympic athletes’ training be hacked?

Lori Ewing (Canadian Press) in an  August 3, 2018 article on the Canadian Broadcasting Corporation news website, heralds a new technology intended for the 2020 Olympics in Tokyo (Japan) but being tested now for the 2018 North American, Central American and Caribbean Athletics Association (NACAC) Track & Field Championships, known as Toronto 2018: Track & Field in the 6ix (Aug. 10-12, 2018) competition.

It’s described as a ‘computerized pill’ that will allow athletes to regulate their body temperature during competition or training workouts, from the August 3, 2018 article,

“We can take someone like Evan [Dunfee, a race walker], have him swallow the little pill, do a full four-hour workout, and then come back and download the whole thing, so we get from data core temperature every 30 seconds through that whole workout,” said Trent Stellingwerff, a sport scientist who works with Canada’s Olympic athletes.

“The two biggest factors of core temperature are obviously the outdoor humidex, heat and humidity, but also exercise intensity.”

Bluetooth technology allows Stellingwerff to gather immediate data with a handheld device — think a tricorder in “Star Trek.” The ingestible device also stores measurements for up to 16 hours when away from the monitor which can be wirelessly transmitted when back in range.

“That pill is going to change the way that we understand how the body responds to heat, because we just get so much information that wasn’t possible before,” Dunfee said. “Swallow a pill, after the race or after the training session, Trent will come up, and just hold the phone [emphasis mine] to your stomach and download all the information. It’s pretty crazy.”

First off, it’s probably not a pill or tablet but a gelcap and it sounds like the device is a wireless biosensor. As Ewing notes, the device collects data and transmits it.

Here’s how the French company, BodyCap, supplying the technology describes their product, from the company’s e-Celsius Performance webpage, (assuming this is the product being used),

Continuous core body temperature measurement

Main applications are:

Risk reduction for people in extreme situations, such as elite athletes. During exercise in a hot environment, thermal stress is amplified by the external temperature and the environment’s humidity. The saturation of the body’s thermoregulation mechanism can quickly cause hyperthermia to levels that may cause nausea, fainting or death.

Performance optimisation for elite athletes.This ingestible pill leaves the user fully mobile. The device keeps a continuous record of temperature during training session, competition and during the recovery phase. The data can then be used to correlate thermoregulation with performances. This enable the development of customised training protocols for each athlete.

e-Celsius Performance® can be used for all sports, including water sports. Its application is best suited to sports that are physically intensive like football, rugby, cycling, long distance running, tennis or those that take place in environments with extreme temperature conditions, like diving or skiing.

e-Celsius Performance®, is a miniaturised ingestible electronic pill that wirelessly transmits a continuous measurement of gastrointestinal temperature. [emphasis mine]

The data are stored on a monitor called e-Viewer Performance®. This device [emphases mine] shows alerts if the measurement is outside the desired range. The activation box is used to turn the pill on from standby mode and connect the e-Celsius Performance pill with the monitor for data collection in either real time or by recovery from the internal memory of e-Celsius Performance®. Each monitor can be used with up to three pills at once to enable extended use.

The monitor’s interface allows the user to download data to a PC/ Mac for storage. The pill is safe, non-invasive and easy to use, leaving the gastric system after one or two days, [emphasis mine] depending on individual transit time.

I found Dunfee’s description mildly confusing but that can be traced to his mention of wireless transmission to a phone. Ewing describes a handheld device which is consistent with the company’s product description. There is no mention of the potential for hacking but I would hope Athletics Canada and BodyCap are keeping up with current concerns over hacking and interference (e.g., Facebook/Cambridge Analytica, Russians and the 2016 US election, Roberto Rocha’s Aug. 3, 2018 article for CBC titled: Data sheds light on how Russian Twitter trolls targeted Canadians, etc.).

Moving on, this type of technology was first featured here in a February 11, 2014 posting (scroll down to the gif where an electronic circuit dissolves in water) and again in a November 23, 2015 posting about wearable and ingestible technologies but this is the first real life application I’ve seen for it.

Coincidentally, an August 2, 2018 Frontiers [Publishing] news release on EurekAlert announced this piece of research (published in June 2018) questioning whether we need this much data and whether these devices work as promoted,

Wearable [and, in the future, ingestible?] devices are increasingly bought to track and measure health and sports performance: [emphasis mine] from the number of steps walked each day to a person’s metabolic efficiency, from the quality of brain function to the quantity of oxygen inhaled while asleep. But the truth is we know very little about how well these sensors and machines work [emphasis mine]– let alone whether they deliver useful information, according to a new review published in Frontiers in Physiology.

“Despite the fact that we live in an era of ‘big data,’ we know surprisingly little about the suitability or effectiveness of these devices,” says lead author Dr Jonathan Peake of the School of Biomedical Sciences and Institute of Health and Biomedical Innovation at the Queensland University of Technology in Australia. “Only five percent of these devices have been formally validated.”

The authors reviewed information on devices used both by everyday people desiring to keep track of their physical and psychological health and by athletes training to achieve certain performance levels. [emphases mine] The devices — ranging from so-called wrist trackers to smart garments and body sensors [emphasis mine] designed to track our body’s vital signs and responses to stress and environmental influences — fall into six categories:

  • devices for monitoring hydration status and metabolism
  • devices, garments and mobile applications for monitoring physical and psychological stress
  • wearable devices that provide physical biofeedback (e.g., muscle stimulation, haptic feedback)
  • devices that provide cognitive feedback and training
  • devices and applications for monitoring and promoting sleep
  • devices and applications for evaluating concussion

The authors investigated key issues, such as: what the technology claims to do; whether the technology has been independently validated against some recognized standards; whether the technology is reliable and what, if any, calibration is needed; and finally, whether the item is commercially available or still under development.

The authors say that technology developed for research purposes generally seems to be more credible than devices created purely for commercial reasons.

“What is critical to understand here is that while most of these technologies are not labeled as ‘medical devices’ per se, their very existence, let alone the accompanying marketing, conveys a sensibility that they can be used to measure a standard of health,” says Peake. “There are ethical issues with this assumption that need to be addressed.” [emphases mine]

For example, self-diagnosis based on self-gathered data could be inconsistent with clinical analysis based on a medical professional’s assessment. And just as body mass index charts of the past really only provided general guidelines and didn’t take into account a person’s genetic predisposition or athletic build, today’s technology is similarly limited.

The authors are particularly concerned about those technologies that seek to confirm or correlate whether someone has sustained or recovered from a concussion, whether from sports or military service.

“We have to be very careful here because there is so much variability,” says Peake. “The technology could be quite useful, but it can’t and should never replace assessment by a trained medical professional.”

Speaking generally again now, Peake says it is important to establish whether using wearable devices affects people’s knowledge and attitude about their own health and whether paying such close attention to our bodies could in fact create a harmful obsession with personal health, either for individuals using the devices, or for family members. Still, self-monitoring may reveal undiagnosed health problems, said Peake, although population data is more likely to point to false positives.

“What we do know is that we need to start studying these devices and the trends they are creating,” says Peake. “This is a booming industry.”

In fact, a March 2018 study by P&S Market Research indicates the wearable market is expected to generate $48.2 billion in revenue by 2023. That’s a mere five years into the future.”

The authors highlight a number of areas for investigation in order to develop reasonable consumer policies around this growing industry. These include how rigorously the device/technology has been evaluated and the strength of evidence that the device/technology actually produces the desired outcomes.

“And I’ll add a final question: Is wearing a device that continuously tracks your body’s actions, your brain activity, and your metabolic function — then wirelessly transmits that data to either a cloud-based databank or some other storage — safe, for users? Will it help us improve our health?” asked Peake. “We need to ask these questions and research the answers.”

The authors were not examining ingestible biosensors nor were they examining any issues related to data about core temperatures but it would seem that some of the same issues could apply especially if and when this technology is brought to the consumer market.

A dance with love and fear: the Yoko Ono exhibit and the Takashi Murakami exhibit in Vancouver (Canada)

It seems Japanese artists are ‘having a moment’. There’s a documentary (Kusama—Infinity) about contemporary Japanese female artist, Yayoi Kusama, making the festival rounds this year (2018). Last year (2017), the British Museum mounted a major exhibition of Hokusai’s work (19th Century) and in 2017, the Metropolitan Museum of Art Costume Institute benefit was inspired by a Japanese fashion designer, “Rei Kawakubo/Comme des Garçons: Art of the In-Between.” (A curator at the Japanese Garden in Portland who had lived in Japan for a number of years mentioned to me during an interview that the Japanese have one word for art. There is no linguistic separation between art and craft.)

More recently, both Yoko Ono and Takashi Murakami have had shows in Vancouver, Canada. Starting with fear as I prefer to end with love, Murakami had a blockbuster show at the Vancouver Gallery.

Takashi Murakami: a dance with fear (and money too)

In the introductory notes at the beginning of the exhibit: “Takashi Murakami: The Octopus Eats Its own Leg,” it was noted that fear is one of Murakami’s themes. The first few pieces in the show had been made to look faded and brownish to the point where you had to work at seeing what was underneath the layers. The images were a little bit like horror films something’s a bit awry then scary and you don’t know what it is or how to deal with it.

After those images, the show opened up to bright, bouncy imagery commonly associated with Mrjakami’s work. However, if you look at them carefully, you’ll see many of these characters have big, pointed teeth. Also featured was a darkened room with two huge warriors.At a guess, I’d say they were 14 feet tall.

It  made for a disconcerting show with its darker themes usually concealed in bright, vibrant colour. Here’s an image promoting Murakami’s Vancouver birthday celebration and exhibit opening,

‘Give me the money, now!’ says a gleeful Takashi Murakami, whose expansive show is currently at the Vancouver Art Gallery. Photo by the VAG. [downloaded from https://thetyee.ca/Culture/2018/02/07/Takashi-Murakami-VAG/]

The colours and artwork shown in the marketing materials (I’m including the wrapping on the gallery itself) were  exuberant as was Murakami who acted as his own marketing material. I’m mentioning the money It’s very intimately and blatantly linked to Murakami’s art and work.  Dorothy Woodend in a Feb. 7, 2018 article for The Tyee puts it this way (Note: Link have been removed),

The close, almost incestuous relationship between art and money is a very old story. [emphasis mine] You might even say it is the only story at the moment.

You can know this, understand it to a certain extent, and still have it rear up and bite you on the bum. [emphasis mine] Such was my experience of attending the exhibition preview of Takashi Murakami’s The Octopus Eats Its Own Leg at the Vancouver Art Gallery.

The show is the first major retrospective of Murakami’s work in Canada, and the VAG has spared no expense in marketing the living hell out of the thing. From the massive cephalopod installed atop the dome of the gallery, to the ocean of smiling cartoon flowers, to the posters papering every inch of downtown Vancouver, it is in a word: huge.

If you don’t know much about Murakami the show is illuminating, in many different ways. Expansive in extremis, the exhibition includes more than 50 works that trace a path through the evolution of Murakami’s style and aesthetic, moving from his early dark textural paintings that blatantly ripped off Anselm Kiefer, to his later pop-art style (Superflat), familiar from Kanye West albums and Louis Vuitton handbags.

make no mistake, money runs underneath the VAG show like an engine [emphasis mine]. You can feel it in the air, thrumming with a strange radioactive current, like a heat mirage coming off the people madly snapping selfies next to the Kanye Bear sculpture.

The artist himself seems particularly aware of how much of a financial edifice surrounds the human impulse to make images. In an on-stage interview with senior VAG [Vancouver Art Gallery] curator Bruce Grenville during a media preview for the show, Murakami spoke plainly about the need for survival (a.k.a. money) [emphasis mine] that has propelled his career.

Even the title of the show speaks to the notion of survival (from Woodend’s article; Note: Links have been removed),

The title of the show takes inspiration from Japanese folklore about a creature that sacrifices part of its own body so that the greater whole might survive. In the natural world, an octopus will chew off its own leg if there is an infection, and then regrow the missing limb. In the art world, the idea pertains to the practice of regurgitating (recycling) old ideas to serve the endless voracious demand for new stuff. “I don’t have the talent to come up with new ideas, so in order to survive, you have to eat your own body,” Murakami explains, citing his need for deadlines, and very bad economic conditions, that lead to a state of almost Dostoyevskyian desperation. “Please give me the money now!” he yells, and the assembled press laughs on cue.

The artist’s responsibility to address larger issues like gender, politics and the environment was the final question posed during the Q&A, before the media were allowed into the gallery to see the work. Murakami took his time before answering, speaking through the nice female translator beside him. “Artists don’t have that much power in the world, but they can speak to the audience of the future, who look at the artwork from a certain era, like Goya paintings, and see not just social commentary, but an artistic point of view. The job of the artist is to dig deep into human beings.”

Which is a nice sentiment to be sure, but increasingly art is about celebrity and profit. Record-breaking shows like Alexander McQueen’s Savage Beauty and Rei Kawakubo/Comme des Garçons: Art of the In-Between demonstrated an easy appeal for both audiences and corporations. One of Murakami’s earlier exhibitions featured a Louis Vuitton pop-up shop as part of the show. Closer to home, the Fight for Beauty exhibit mixed fashion, art and development in a decidedly queasy-making mixture.

There is money to be made in culture of a certain scale, with scale being the operative word. Get big or get out.

Woodend also relates the show and some of the issues it raises to the local scene (Note: Links have been removed),

A recent article in the Vancouver Courier about the Oakridge redevelopment plans highlighted the relationship between development and culture in raw numbers: “1,000,000 square feet of retail, 2,600 homes for 6,000 people, office space for 3,000 workers, a 100,000-square-foot community centre and daycare, the city’s second-largest library, a performing arts academy, a live music venue for 3,000 people and the largest public art program in Vancouver’s history…”

Westbank’s Ian Gillespie [who hosted the Fight for Beauty exhibit] was quoted extensively, outlining the integration between the city and the developer. “The development team will also work with the city’s chief librarian to figure out the future of the library, while the 3,000-seat music venue will create an ‘incredible music scene.’” The term “cultural hub” also pops up so many times it’s almost funny, in a horrifying kind of way.

But bigness often squeezes out artists and musicians who simply can’t compete. Folk who can’t fill a 3,000-seat venue, or pack in thousands of visitors, like the Murakami show, are out of luck.

Vancouver artists, who struggle to survive in the city and have done so for quite some time, were singularly unimpressed with the Oakridge development proposal. Selina Crammond, a local musician and all-around firebrand, summed up the divide in a few eloquent sentences: “I mean really, who is going to make up this ‘incredible music scene’ and fill all of these shiny new venues? Many of my favourite local musicians have already moved away from Vancouver because they just can’t make it work. Who’s going to pay the musicians and workers? Who’s going to pay the large ticket prices to be able to maintain these spaces? I don’t think space is the problem. I think affordability and distribution of wealth and funding are the problems artists and arts workers are facing.”

The stories continue to pop up, the most recent being the possible sale and redevelopment of the Rio Theatre. The news sparked an outpouring of anger, but the story is repeated so often in Vancouver, it has become something of a cliché. You need only to look at the story of the Hollywood Theatre for a likely ending to the saga.

Which brings me back around to the Murakami exhibit. To be perfectly frank, the show is incredible and well-worth visiting. I enjoyed every minute of wandering through it taking in the sheer expanse of mind-boggling, googly-eyed detail. I would urge you to attend, if you can afford it. But there’s the rub. I was there for free, and general admission to the VAG is $22.86. This may not seem like a lot, but in a city where people can barely make rent, culture becomes the purview of them that can afford it.

The City of Vancouver recently launched its Creative Cities initiative to look at issues of affordability, diversity and gentrification.

We shall see if anything real emerges from the process. But in the meantime, Vancouver artists might have to eat their own legs simply to survive. [Tyee]

Survival issues and their intimate companions, fear, are clearly a major focus for Murakami’s art.

For the curious, the Vancouver version of the Murakami retrospective show was held from February 3 – May 6, 2018. There are still some materials about the show available online here.

Yoko Ono and the power of love (and maybe money, too)

More or less concurrently with the Murakami exhibition, the Rennie Museum (formerly Rennie Collection), came back from a several month hiatus to host a show featuring Yoko Ono’s “Mend Piece.”

From a Rennie Museum (undated) press release,

Rennie Museum is pleased to present Yoko Ono’s MEND PIECE, Andrea Rosen Gallery, New York City version (1966/2015). Illustrating Ono’s long standing artistic quest in social activism and world peace, this instructional work will transform the historic Wing Sang building into an intimate space for creative expression and bring people together in an act of collective healing and meditation. The installation will run from March 1 to April 15, 2018.

First conceptualized in 1966, the work immerses the visitor in a dream-like state. Viewers enter into an all-white space and are welcomed to take a seat at the table to reassemble fragments of ceramic coffee cups and saucers using the provided twine, tape, and glue. Akin to the Japanese philosophy of Wabi-sabi, an embracing of the flawed or imperfect, Mend Piece encourages the participant to transform broken fragments into an object that prevails its own violent rupture. The mended pieces are then displayed on shelves installed around the room. The contemplative act of mending is intended to promote reparation starting within one’s self and community, and bridge the gap created by violence, hatred, and war. In the words of Yoko Ono herself, “Mend with wisdom, mend with love. It will mend the earth at the same time.”

The installation of MEND PIECE, Andrea Rosen Gallery, New York City version at Rennie Museum will be accompanied by an espresso bar, furthering the notions of community and togetherness.

Yoko Ono (b. 1933) is a Japanese conceptual artist, musician, and peace activist pioneering feminism and Fluxus art. Her eclectic oeuvre of performance art, paintings, sculptures, films and sound works have been shown at renowned institutions worldwide, with recent exhibitions at The Museum of Modern Art, New York; Copenhagen Contemporary, Copenhagen; Museum of Contemporary Art, Tokyo; and Museo de Arte Latinoamericano de Buenos Aires. She is the recipient of the 2005 IMAJINE Lifetime Achievement Award and the 2009 Venice Biennale Golden Lion for Lifetime Achievement, among other distinctions. She lives and works in New York City.

While most of the shows have taken place over two, three, or four floors, “Mend Piece” was on the main floor only,

There was another “Mend Piece” in Canada, located at the Gardiner Museum and part of a larger show titled: “The Riverbed,” which ran from February 22 to June 3, 2018. Here’s an image of one of the Gardiner Museum “Mend” pieces that was featured in a March 7, 2018 article by Sonya Davidson for the Toronto Guardian,

Here’s what Davidson had to say about the three-part installation, “The Riverbed,”

I’m sitting  on one of the cushions placed on the floor watching the steady stream of visitors at Yoko Ono’s exhibition The Riverbed at the Gardiner Museum. The room is airy and bright but void of  colours yet it’s vibrant and alive in a calming way. There are three distinct areas in this exhibition: Stone Piece, Line Piece and Mend Piece. From what I’ve experienced in Ono’s previous exhibitions, her work encourages participation and is inclusive of everyone. She has the idea. She encourages us to  go collaborate with her. Her work is describe often as  redirecting our attention to ideas, instead of appearances.

Mend Piece is the one I’m most familiar with. It was part of her exhibition I visited in Reykjavik [Iceland]. Two large communal tables are filled with broken ceramic pieces and mending elements. Think glue, string, and tape.  Instructions from Ono once again are simple but with meaning. Take the pieces that resonate with you and mend them as you desire. You’re encourage [sic] to leave it in the communal space for everyone to experience what you’ve experienced. It reminded me of her work decades ago where she shattered porcelain vases, and people invited people to take a piece with them. But then years later she collected as many back and mended them herself. Part contemporary with a nod to the traditional Japanese art form of Kintsugi – fixing broken pottery with gold and the philosophy of nothing is ever truly broken. The repairs made are part of the history and should be embraced with honour and pride.

The experience at the Rennie was markedly different . I recommend reading both Davidson’s piece (includes many embedded images) in its entirety to get a sense for how different and this April 7, 2018 article by Jenna Moon for The Star regarding the theft of a stone from The Riverbed show at the Gardiner,

A rock bearing Yoko Ono’s handwriting has been stolen from the Gardiner Museum, Toronto police say. The theft reportedly occurred around 5:30 p.m. on March 12.

The rock is part of an art exhibit featuring Ono, where patrons can meditate using several river rocks. The stone is inscribed with black ink, and reads “love yourself” in block letters. It is valued at $17,500 (U.S.), [emphasis mine] Toronto police media officer Gary Long told the Star Friday evening.

As far as I can tell, they still haven’t found the suspect who was described as a woman between the ages of 55 and 60. However the question that most interests me is how did they arrive at a value for the stone? Was it a case of assigning a value to the part of the installation with the stones and dividing that value by the number of stones? Yoko Ono may focus her art on social activism and peace but she too needs money to survive. Moving on.

Musings on ‘mend’

Participating in “Mend Piece” at the Rennie Museum was revelatory. It was a direct experience of the “traditional Japanese art form of Kintsugi – fixing broken pottery with gold and the philosophy of nothing is ever truly broken.” So often art is at best a tertiary experience for the viewer. The artist has the primary experience producing the work and the curator has the secondary experience of putting the show together.

For all the talk about interactive installations and pieces, there are few that truly engage the viewer with the piece. I find this rule applies: the more technology, the less interactivity.

“Mend” insisted on interactivity. More or less. I went with a friend and sat beside the one person in the group who didn’t want to talk to anyone. And she wasn’t just quiet, you could feel the “don’t talk to me” vibrations pouring from every one of her body parts.

The mending sessions were about 30 minutes long and, as Davidson notes, you had string, two types of glue, and twine. For someone with any kind of perfectionist tendencies (me) and a lack of crafting skills (me), it proved to be a bit of a challenge, especially with a semi-hostile person beside me. Thank goodness my friend was on the other side.

Adding to my travails was the gallery assistant (a local art student) who got very anxious and hovered over me as I attempted and failed to set my piece on a ledge in the room (twice). She was very nice and happy to share, without being intrusive, information about Yoko Ono and her work while we were constructing our pieces. I’m not sure what she thought was going to happen when I started dropping things but her hovering brought back memories of my adolescence when shopkeepers would follow me around their store.

Most of my group had finished and even though there was still time in my session, the next group rushed in and took my seat while I failed for the second time to place my piece. I stood for my third (and thankfully successful) repair attempt.

At that point I went to the back where more of the “Mend” communal experience awaited. Unfortunately, the coffee bar’s (this put up especially for the show) espresso machine was not working. There was some poetry on the walls and a video highlighting Yoko Ono’s work over the years and the coffee bar attendant was eager to share (but not intrusively so) some information about Yoko and her work.

As I stated earlier, it was a revelatory experience. First, It turned out my friend had been following Yoko’s work since before the artist had hooked up with John Lennon and she was able to add details to the attendants’ comments.

Second, I didn’t expect was a confrontation with the shards of my past and personality. In essence, mending myself and, hopefully, more. There was my perfectionism, rejection by the unfriendly tablemate, my emotional response (unspoken) to the hypervigilant gallery assistant, having my seat taken from me before the time was up, and the disappointment of the coffee bar. There was also a rediscovery of my friend, a friendly tablemate who made a beautiful object (it looked like a bird), the helpfulness of both the gallery assistants, Yoko Ono’s poetry, and a documentary about the remarkable Yoko.

All in all, it was a perfect reflection of imperfection (wabi-sabi), brokenness, and wounding in the context of repair (Kintsugi)/healing.

Thank you, Yoko Ono.

For anyone in Vancouver who feels they missed out on the experience, there are some performances of “Perfect Imperfections: The Art of a Messy Life” (comedy, dance, and live music) at Vancity Culture Lab at The Cultch from June 14 – 16, 2018. You can find out more here.

The moment

It certainly seems as if there’s a great interest in Japanese art, if you live in Vancouver (Canada), anyway. The Murakami show was a huge success for the Vancouver Art Gallery. As for Yoko Ono, the Rennie Museum extended the exhibit dates due to demand. Plus, the 2018 – 2020 version of the Vancouver Biennale is featuring (from a May 29, 2018 Vancouver Biennale news release),

… Yoko Ono with its 2018 Distinguished Artist Award, a recognition that coincides with reissuing the acclaimed artist’s 2007 Biennale installation, “IMAGINE PEACE,” marshalled at this critical time to re-inspire a global consciousness towards unity, harmony, and accord. Yoko Ono’s project exemplifies the Vancouver Biennale’s mission for diverse communities to gain access, visibility and representation.

The British Museum’s show (May 25 – August 13, 2017), “Hokusai’s Great Wave,” was seen in Vancouver at a special preview event in May 2017 at a local movie house, which was packed.

The documentary film festival, DOXA (Vancouver) closed its 2018 iteration with the documentary about Yayoi Kusama. Here’s more about her from a May 9, 2018 article by Janet Smith for the Georgia Straight,

Amid all the dizzying, looped-and-dotted works that American director Heather Lenz has managed to capture in her new documentary Kusama—Infinity, perhaps nothing stands out so much as images of the artist today in her Shinjuku studio.

Interviewed in the film, the 89-year-old Yayoi Kusama sports a signature scarlet bobbed anime wig and hot-pink polka-dotted dress, sitting with her marker at a drawing table, and set against the recent creations on her wall—a sea of black-and-white spots and jaggedy lines.

“The boundary between Yayoi Kusama and her art is not very great,” Lenz tells the Straight from her home in Orange County. “They are one and the same.”

It was as a young student majoring in art history and fine art that Lenz was first drawn to Kusama—who stood out as one of few female artists in her textbooks. She saw an underappreciated talent whose avant-pop works anticipated Andy Warhol and others. And as Lenz dug deeper into the artist’s story, she found a woman whose struggles with a difficult childhood and mental illness made her achievements all the more remarkable.

Today, Kusama is one of the world’s most celebrated female artists, her kaleidoscopic, multiroom show Infinity Mirrors drawing throngs of visitors to galleries like the Art Gallery of Ontario and the Seattle Art Museum over the past year. But when Lenz set out to make her film 17 long years ago, few had ever heard of Kusama.

I am hopeful that this is a sign that the Vancouver art scene is focusing more attention to the west, to Asia. Quite frankly, it’s about time.

As a special treat, here’s a ‘Yoko Ono tribute’ from the Bare Naked Ladies,

The Hedy Lamarr of international research: Canada’s Third assessment of The State of Science and Technology and Industrial Research and Development in Canada (1 of 2)

Before launching into the assessment, a brief explanation of my theme: Hedy Lamarr was considered to be one of the great beauties of her day,

“Ziegfeld Girl” Hedy Lamarr 1941 MGM *M.V.
Titles: Ziegfeld Girl
People: Hedy Lamarr

Aside from starring in Hollywood movies and, before that, movies in Europe, she was also an inventor and not just any inventor (from a Dec. 4, 2017 article by Laura Barnett for The Guardian), Note: Links have been removed,

Let’s take a moment to reflect on the mercurial brilliance of Hedy Lamarr. Not only did the Vienna-born actor flee a loveless marriage to a Nazi arms dealer to secure a seven-year, $3,000-a-week contract with MGM, and become (probably) the first Hollywood star to simulate a female orgasm on screen – she also took time out to invent a device that would eventually revolutionise mobile communications.

As described in unprecedented detail by the American journalist and historian Richard Rhodes in his new book, Hedy’s Folly, Lamarr and her business partner, the composer George Antheil, were awarded a patent in 1942 for a “secret communication system”. It was meant for radio-guided torpedoes, and the pair gave to the US Navy. It languished in their files for decades before eventually becoming a constituent part of GPS, Wi-Fi and Bluetooth technology.

(The article goes on to mention other celebrities [Marlon Brando, Barbara Cartland, Mark Twain, etc] and their inventions.)

Lamarr’s work as an inventor was largely overlooked until the 1990’s when the technology community turned her into a ‘cultish’ favourite and from there her reputation grew and acknowledgement increased culminating in Rhodes’ book and the documentary by Alexandra Dean, ‘Bombshell: The Hedy Lamarr Story (to be broadcast as part of PBS’s American Masters series on May 18, 2018).

Canada as Hedy Lamarr

There are some parallels to be drawn between Canada’s S&T and R&D (science and technology; research and development) and Ms. Lamarr. Chief amongst them, we’re not always appreciated for our brains. Not even by people who are supposed to know better such as the experts on the panel for the ‘Third assessment of The State of Science and Technology and Industrial Research and Development in Canada’ (proper title: Competing in a Global Innovation Economy: The Current State of R&D in Canada) from the Expert Panel on the State of Science and Technology and Industrial Research and Development in Canada.

A little history

Before exploring the comparison to Hedy Lamarr further, here’s a bit more about the history of this latest assessment from the Council of Canadian Academies (CCA), from the report released April 10, 2018,

This assessment of Canada’s performance indicators in science, technology, research, and innovation comes at an opportune time. The Government of Canada has expressed a renewed commitment in several tangible ways to this broad domain of activity including its Innovation and Skills Plan, the announcement of five superclusters, its appointment of a new Chief Science Advisor, and its request for the Fundamental Science Review. More specifically, the 2018 Federal Budget demonstrated the government’s strong commitment to research and innovation with historic investments in science.

The CCA has a decade-long history of conducting evidence-based assessments about Canada’s research and development activities, producing seven assessments of relevance:

The State of Science and Technology in Canada (2006) [emphasis mine]
•Innovation and Business Strategy: Why Canada Falls Short (2009)
•Catalyzing Canada’s Digital Economy (2010)
•Informing Research Choices: Indicators and Judgment (2012)
The State of Science and Technology in Canada (2012) [emphasis mine]
The State of Industrial R&D in Canada (2013) [emphasis mine]
•Paradox Lost: Explaining Canada’s Research Strength and Innovation Weakness (2013)

Using similar methods and metrics to those in The State of Science and Technology in Canada (2012) and The State of Industrial R&D in Canada (2013), this assessment tells a similar and familiar story: Canada has much to be proud of, with world-class researchers in many domains of knowledge, but the rest of the world is not standing still. Our peers are also producing high quality results, and many countries are making significant commitments to supporting research and development that will position them to better leverage their strengths to compete globally. Canada will need to take notice as it determines how best to take action. This assessment provides valuable material for that conversation to occur, whether it takes place in the lab or the legislature, the bench or the boardroom. We also hope it will be used to inform public discussion. [p. ix Print, p. 11 PDF]

This latest assessment succeeds the general 2006 and 2012 reports, which were mostly focused on academic research, and combines it with an assessment of industrial research, which was previously separate. Also, this third assessment’s title (Competing in a Global Innovation Economy: The Current State of R&D in Canada) makes what was previously quietly declared in the text, explicit from the cover onwards. It’s all about competition, despite noises such as the 2017 Naylor report (Review of fundamental research) about the importance of fundamental research.

One other quick comment, I did wonder in my July 1, 2016 posting (featuring the announcement of the third assessment) how combining two assessments would impact the size of the expert panel and the size of the final report,

Given the size of the 2012 assessment of science and technology at 232 pp. (PDF) and the 2013 assessment of industrial research and development at 220 pp. (PDF) with two expert panels, the imagination boggles at the potential size of the 2016 expert panel and of the 2016 assessment combining the two areas.

I got my answer with regard to the panel as noted in my Oct. 20, 2016 update (which featured a list of the members),

A few observations, given the size of the task, this panel is lean. As well, there are three women in a group of 13 (less than 25% representation) in 2016? It’s Ontario and Québec-dominant; only BC and Alberta rate a representative on the panel. I hope they will find ways to better balance this panel and communicate that ‘balanced story’ to the rest of us. On the plus side, the panel has representatives from the humanities, arts, and industry in addition to the expected representatives from the sciences.

The imbalance I noted then was addressed, somewhat, with the selection of the reviewers (from the report released April 10, 2018),

The CCA wishes to thank the following individuals for their review of this report:

The proportion of women to men as reviewers jumped up to about 36% (4 of 11 reviewers) and there are two reviewers from the Maritime provinces. As usual, reviewers external to Canada were from Europe. Although this time, they came from Dutch institutions rather than UK or German institutions. Interestingly and unusually, there was no one from a US institution. When will they start using reviewers from other parts of the world?

As for the report itself, it is 244 pp. (PDF). (For the really curious, I have a  December 15, 2016 post featuring my comments on the preliminary data for the third assessment.)

To sum up, they had a lean expert panel tasked with bringing together two inquiries and two reports. I imagine that was daunting. Good on them for finding a way to make it manageable.

Bibliometrics, patents, and a survey

I wish more attention had been paid to some of the issues around open science, open access, and open data, which are changing how science is being conducted. (I have more about this from an April 5, 2018 article by James Somers for The Atlantic but more about that later.) If I understand rightly, they may not have been possible due to the nature of the questions posed by the government when requested the assessment.

As was done for the second assessment, there is an acknowledgement that the standard measures/metrics (bibliometrics [no. of papers published, which journals published them; number of times papers were cited] and technometrics [no. of patent applications, etc.] of scientific accomplishment and progress are not the best and new approaches need to be developed and adopted (from the report released April 10, 2018),

It is also worth noting that the Panel itself recognized the limits that come from using traditional historic metrics. Additional approaches will be needed the next time this assessment is done. [p. ix Print; p. 11 PDF]

For the second assessment and as a means of addressing some of the problems with metrics, the panel decided to take a survey which the panel for the third assessment has also done (from the report released April 10, 2018),

The Panel relied on evidence from multiple sources to address its charge, including a literature review and data extracted from statistical agencies and organizations such as Statistics Canada and the OECD. For international comparisons, the Panel focused on OECD countries along with developing countries that are among the top 20 producers of peer-reviewed research publications (e.g., China, India, Brazil, Iran, Turkey). In addition to the literature review, two primary research approaches informed the Panel’s assessment:
•a comprehensive bibliometric and technometric analysis of Canadian research publications and patents; and,
•a survey of top-cited researchers around the world.

Despite best efforts to collect and analyze up-to-date information, one of the Panel’s findings is that data limitations continue to constrain the assessment of R&D activity and excellence in Canada. This is particularly the case with industrial R&D and in the social sciences, arts, and humanities. Data on industrial R&D activity continue to suffer from time lags for some measures, such as internationally comparable data on R&D intensity by sector and industry. These data also rely on industrial categories (i.e., NAICS and ISIC codes) that can obscure important trends, particularly in the services sector, though Statistics Canada’s recent revisions to how this data is reported have improved this situation. There is also a lack of internationally comparable metrics relating to R&D outcomes and impacts, aside from those based on patents.

For the social sciences, arts, and humanities, metrics based on journal articles and other indexed publications provide an incomplete and uneven picture of research contributions. The expansion of bibliometric databases and methodological improvements such as greater use of web-based metrics, including paper views/downloads and social media references, will support ongoing, incremental improvements in the availability and accuracy of data. However, future assessments of R&D in Canada may benefit from more substantive integration of expert review, capable of factoring in different types of research outputs (e.g., non-indexed books) and impacts (e.g., contributions to communities or impacts on public policy). The Panel has no doubt that contributions from the humanities, arts, and social sciences are of equal importance to national prosperity. It is vital that such contributions are better measured and assessed. [p. xvii Print; p. 19 PDF]

My reading: there’s a problem and we’re not going to try and fix it this time. Good luck to those who come after us. As for this line: “The Panel has no doubt that contributions from the humanities, arts, and social sciences are of equal importance to national prosperity.” Did no one explain that when you use ‘no doubt’, you are introducing doubt? It’s a cousin to ‘don’t take this the wrong way’ and ‘I don’t mean to be rude but …’ .

Good news

This is somewhat encouraging (from the report released April 10, 2018),

Canada’s international reputation for its capacity to participate in cutting-edge R&D is strong, with 60% of top-cited researchers surveyed internationally indicating that Canada hosts world-leading infrastructure or programs in their fields. This share increased by four percentage points between 2012 and 2017. Canada continues to benefit from a highly educated population and deep pools of research skills and talent. Its population has the highest level of educational attainment in the OECD in the proportion of the population with
a post-secondary education. However, among younger cohorts (aged 25 to 34), Canada has fallen behind Japan and South Korea. The number of researchers per capita in Canada is on a par with that of other developed countries, andincreased modestly between 2004 and 2012. Canada’s output of PhD graduates has also grown in recent years, though it remains low in per capita terms relative to many OECD countries. [pp. xvii-xviii; pp. 19-20]

Don’t let your head get too big

Most of the report observes that our international standing is slipping in various ways such as this (from the report released April 10, 2018),

In contrast, the number of R&D personnel employed in Canadian businesses
dropped by 20% between 2008 and 2013. This is likely related to sustained and
ongoing decline in business R&D investment across the country. R&D as a share
of gross domestic product (GDP) has steadily declined in Canada since 2001,
and now stands well below the OECD average (Figure 1). As one of few OECD
countries with virtually no growth in total national R&D expenditures between
2006 and 2015, Canada would now need to more than double expenditures to
achieve an R&D intensity comparable to that of leading countries.

Low and declining business R&D expenditures are the dominant driver of this
trend; however, R&D spending in all sectors is implicated. Government R&D
expenditures declined, in real terms, over the same period. Expenditures in the
higher education sector (an indicator on which Canada has traditionally ranked
highly) are also increasing more slowly than the OECD average. Significant
erosion of Canada’s international competitiveness and capacity to participate
in R&D and innovation is likely to occur if this decline and underinvestment
continue.

Between 2009 and 2014, Canada produced 3.8% of the world’s research
publications, ranking ninth in the world. This is down from seventh place for
the 2003–2008 period. India and Italy have overtaken Canada although the
difference between Italy and Canada is small. Publication output in Canada grew
by 26% between 2003 and 2014, a growth rate greater than many developed
countries (including United States, France, Germany, United Kingdom, and
Japan), but below the world average, which reflects the rapid growth in China
and other emerging economies. Research output from the federal government,
particularly the National Research Council Canada, dropped significantly
between 2009 and 2014.(emphasis mine)  [p. xviii Print; p. 20 PDF]

For anyone unfamiliar with Canadian politics,  2009 – 2014 were years during which Stephen Harper’s Conservatives formed the government. Justin Trudeau’s Liberals were elected to form the government in late 2015.

During Harper’s years in government, the Conservatives were very interested in changing how the National Research Council of Canada operated and, if memory serves, the focus was on innovation over research. Consequently, the drop in their research output is predictable.

Given my interest in nanotechnology and other emerging technologies, this popped out (from the report released April 10, 2018),

When it comes to research on most enabling and strategic technologies, however, Canada lags other countries. Bibliometric evidence suggests that, with the exception of selected subfields in Information and Communication Technologies (ICT) such as Medical Informatics and Personalized Medicine, Canada accounts for a relatively small share of the world’s research output for promising areas of technology development. This is particularly true for Biotechnology, Nanotechnology, and Materials science [emphasis mine]. Canada’s research impact, as reflected by citations, is also modest in these areas. Aside from Biotechnology, none of the other subfields in Enabling and Strategic Technologies has an ARC rank among the top five countries. Optoelectronics and photonics is the next highest ranked at 7th place, followed by Materials, and Nanoscience and Nanotechnology, both of which have a rank of 9th. Even in areas where Canadian researchers and institutions played a seminal role in early research (and retain a substantial research capacity), such as Artificial Intelligence and Regenerative Medicine, Canada has lost ground to other countries.

Arguably, our early efforts in artificial intelligence wouldn’t have garnered us much in the way of ranking and yet we managed some cutting edge work such as machine learning. I’m not suggesting the expert panel should have or could have found some way to measure these kinds of efforts but I’m wondering if there could have been some acknowledgement in the text of the report. I’m thinking a couple of sentences in a paragraph about the confounding nature of scientific research where areas that are ignored for years and even decades then become important (e.g., machine learning) but are not measured as part of scientific progress until after they are universally recognized.

Still, point taken about our diminishing returns in ’emerging’ technologies and sciences (from the report released April 10, 2018),

The impression that emerges from these data is sobering. With the exception of selected ICT subfields, such as Medical Informatics, bibliometric evidence does not suggest that Canada excels internationally in most of these research areas. In areas such as Nanotechnology and Materials science, Canada lags behind other countries in levels of research output and impact, and other countries are outpacing Canada’s publication growth in these areas — leading to declining shares of world publications. Even in research areas such as AI, where Canadian researchers and institutions played a foundational role, Canadian R&D activity is not keeping pace with that of other countries and some researchers trained in Canada have relocated to other countries (Section 4.4.1). There are isolated exceptions to these trends, but the aggregate data reviewed by this Panel suggest that Canada is not currently a world leader in research on most emerging technologies.

The Hedy Lamarr treatment

We have ‘good looks’ (arts and humanities) but not the kind of brains (physical sciences and engineering) that people admire (from the report released April 10, 2018),

Canada, relative to the world, specializes in subjects generally referred to as the
humanities and social sciences (plus health and the environment), and does
not specialize as much as others in areas traditionally referred to as the physical
sciences and engineering. Specifically, Canada has comparatively high levels
of research output in Psychology and Cognitive Sciences, Public Health and
Health Services, Philosophy and Theology, Earth and Environmental Sciences,
and Visual and Performing Arts. [emphases mine] It accounts for more than 5% of world researchin these fields. Conversely, Canada has lower research output than expected
in Chemistry, Physics and Astronomy, Enabling and Strategic Technologies,
Engineering, and Mathematics and Statistics. The comparatively low research
output in core areas of the natural sciences and engineering is concerning,
and could impair the flexibility of Canada’s research base, preventing research
institutions and researchers from being able to pivot to tomorrow’s emerging
research areas. [p. xix Print; p. 21 PDF]

Couldn’t they have used a more buoyant tone? After all, science was known as ‘natural philosophy’ up until the 19th century. As for visual and performing arts, let’s include poetry as a performing and literary art (both have been the case historically and cross-culturally) and let’s also note that one of the great physics texts, (De rerum natura by Lucretius) was a multi-volume poem (from Lucretius’ Wikipedia entry; Note: Links have been removed).

His poem De rerum natura (usually translated as “On the Nature of Things” or “On the Nature of the Universe”) transmits the ideas of Epicureanism, which includes Atomism [the concept of atoms forming materials] and psychology. Lucretius was the first writer to introduce Roman readers to Epicurean philosophy.[15] The poem, written in some 7,400 dactylic hexameters, is divided into six untitled books, and explores Epicurean physics through richly poetic language and metaphors. Lucretius presents the principles of atomism; the nature of the mind and soul; explanations of sensation and thought; the development of the world and its phenomena; and explains a variety of celestial and terrestrial phenomena. The universe described in the poem operates according to these physical principles, guided by fortuna, “chance”, and not the divine intervention of the traditional Roman deities.[16]

Should you need more proof that the arts might have something to contribute to physical sciences, there’s this in my March 7, 2018 posting,

It’s not often you see research that combines biologically inspired engineering and a molecular biophysicist with a professional animator who worked at Peter Jackson’s (Lord of the Rings film trilogy, etc.) Park Road Post film studio. An Oct. 18, 2017 news item on ScienceDaily describes the project,

Like many other scientists, Don Ingber, M.D., Ph.D., the Founding Director of the Wyss Institute, [emphasis mine] is concerned that non-scientists have become skeptical and even fearful of his field at a time when technology can offer solutions to many of the world’s greatest problems. “I feel that there’s a huge disconnect between science and the public because it’s depicted as rote memorization in schools, when by definition, if you can memorize it, it’s not science,” says Ingber, who is also the Judah Folkman Professor of Vascular Biology at Harvard Medical School and the Vascular Biology Program at Boston Children’s Hospital, and Professor of Bioengineering at the Harvard Paulson School of Engineering and Applied Sciences (SEAS). [emphasis mine] “Science is the pursuit of the unknown. We have a responsibility to reach out to the public and convey that excitement of exploration and discovery, and fortunately, the film industry is already great at doing that.”

“Not only is our physics-based simulation and animation system as good as other data-based modeling systems, it led to the new scientific insight [emphasis mine] that the limited motion of the dynein hinge focuses the energy released by ATP hydrolysis, which causes dynein’s shape change and drives microtubule sliding and axoneme motion,” says Ingber. “Additionally, while previous studies of dynein have revealed the molecule’s two different static conformations, our animation visually depicts one plausible way that the protein can transition between those shapes at atomic resolution, which is something that other simulations can’t do. The animation approach also allows us to visualize how rows of dyneins work in unison, like rowers pulling together in a boat, which is difficult using conventional scientific simulation approaches.”

It comes down to how we look at things. Yes, physical sciences and engineering are very important. If the report is to be believed we have a very highly educated population and according to PISA scores our students rank highly in mathematics, science, and reading skills. (For more information on Canada’s latest PISA scores from 2015 see this OECD page. As for PISA itself, it’s an OECD [Organization for Economic Cooperation and Development] programme where 15-year-old students from around the world are tested on their reading, mathematics, and science skills, you can get some information from my Oct. 9, 2013 posting.)

Is it really so bad that we choose to apply those skills in fields other than the physical sciences and engineering? It’s a little bit like Hedy Lamarr’s problem except instead of being judged for our looks and having our inventions dismissed, we’re being judged for not applying ourselves to physical sciences and engineering and having our work in other closely aligned fields dismissed as less important.

Canada’s Industrial R&D: an oft-told, very sad story

Bemoaning the state of Canada’s industrial research and development efforts has been a national pastime as long as I can remember. Here’s this from the report released April 10, 2018,

There has been a sustained erosion in Canada’s industrial R&D capacity and competitiveness. Canada ranks 33rd among leading countries on an index assessing the magnitude, intensity, and growth of industrial R&D expenditures. Although Canada is the 11th largest spender, its industrial R&D intensity (0.9%) is only half the OECD average and total spending is declining (−0.7%). Compared with G7 countries, the Canadian portfolio of R&D investment is more concentrated in industries that are intrinsically not as R&D intensive. Canada invests more heavily than the G7 average in oil and gas, forestry, machinery and equipment, and finance where R&D has been less central to business strategy than in many other industries. …  About 50% of Canada’s industrial R&D spending is in high-tech sectors (including industries such as ICT, aerospace, pharmaceuticals, and automotive) compared with the G7 average of 80%. Canadian Business Enterprise Expenditures on R&D (BERD) intensity is also below the OECD average in these sectors. In contrast, Canadian investment in low and medium-low tech sectors is substantially higher than the G7 average. Canada’s spending reflects both its long-standing industrial structure and patterns of economic activity.

R&D investment patterns in Canada appear to be evolving in response to global and domestic shifts. While small and medium-sized enterprises continue to perform a greater share of industrial R&D in Canada than in the United States, between 2009 and 2013, there was a shift in R&D from smaller to larger firms. Canada is an increasingly attractive place to conduct R&D. Investment by foreign-controlled firms in Canada has increased to more than 35% of total R&D investment, with the United States accounting for more than half of that. [emphasis mine]  Multinational enterprises seem to be increasingly locating some of their R&D operations outside their country of ownership, possibly to gain proximity to superior talent. Increasing foreign-controlled R&D, however, also could signal a long-term strategic loss of control over intellectual property (IP) developed in this country, ultimately undermining the government’s efforts to support high-growth firms as they scale up. [pp. xxii-xxiii Print; pp. 24-25 PDF]

Canada has been known as a ‘branch plant’ economy for decades. For anyone unfamiliar with the term, it means that companies from other countries come here, open up a branch and that’s how we get our jobs as we don’t have all that many large companies here. Increasingly, multinationals are locating R&D shops here.

While our small to medium size companies fund industrial R&D, it’s large companies (multinationals) which can afford long-term and serious investment in R&D. Luckily for companies from other countries, we have a well-educated population of people looking for jobs.

In 2017, we opened the door more widely so we can scoop up talented researchers and scientists from other countries, from a June 14, 2017 article by Beckie Smith for The PIE News,

Universities have welcomed the inclusion of the work permit exemption for academic stays of up to 120 days in the strategy, which also introduces expedited visa processing for some highly skilled professions.

Foreign researchers working on projects at a publicly funded degree-granting institution or affiliated research institution will be eligible for one 120-day stay in Canada every 12 months.

And universities will also be able to access a dedicated service channel that will support employers and provide guidance on visa applications for foreign talent.

The Global Skills Strategy, which came into force on June 12 [2017], aims to boost the Canadian economy by filling skills gaps with international talent.

As well as the short term work permit exemption, the Global Skills Strategy aims to make it easier for employers to recruit highly skilled workers in certain fields such as computer engineering.

“Employers that are making plans for job-creating investments in Canada will often need an experienced leader, dynamic researcher or an innovator with unique skills not readily available in Canada to make that investment happen,” said Ahmed Hussen, Minister of Immigration, Refugees and Citizenship.

“The Global Skills Strategy aims to give those employers confidence that when they need to hire from abroad, they’ll have faster, more reliable access to top talent.”

Coincidentally, Microsoft, Facebook, Google, etc. have announced, in 2017, new jobs and new offices in Canadian cities. There’s a also Chinese multinational telecom company Huawei Canada which has enjoyed success in Canada and continues to invest here (from a Jan. 19, 2018 article about security concerns by Matthew Braga for the Canadian Broadcasting Corporation (CBC) online news,

For the past decade, Chinese tech company Huawei has found no shortage of success in Canada. Its equipment is used in telecommunications infrastructure run by the country’s major carriers, and some have sold Huawei’s phones.

The company has struck up partnerships with Canadian universities, and say it is investing more than half a billion dollars in researching next generation cellular networks here. [emphasis mine]

While I’m not thrilled about using patents as an indicator of progress, this is interesting to note (from the report released April 10, 2018),

Canada produces about 1% of global patents, ranking 18th in the world. It lags further behind in trademark (34th) and design applications (34th). Despite relatively weak performance overall in patents, Canada excels in some technical fields such as Civil Engineering, Digital Communication, Other Special Machines, Computer Technology, and Telecommunications. [emphases mine] Canada is a net exporter of patents, which signals the R&D strength of some technology industries. It may also reflect increasing R&D investment by foreign-controlled firms. [emphasis mine] [p. xxiii Print; p. 25 PDF]

Getting back to my point, we don’t have large companies here. In fact, the dream for most of our high tech startups is to build up the company so it’s attractive to buyers, sell, and retire (hopefully before the age of 40). Strangely, the expert panel doesn’t seem to share my insight into this matter,

Canada’s combination of high performance in measures of research output and impact, and low performance on measures of industrial R&D investment and innovation (e.g., subpar productivity growth), continue to be viewed as a paradox, leading to the hypothesis that barriers are impeding the flow of Canada’s research achievements into commercial applications. The Panel’s analysis suggests the need for a more nuanced view. The process of transforming research into innovation and wealth creation is a complex multifaceted process, making it difficult to point to any definitive cause of Canada’s deficit in R&D investment and productivity growth. Based on the Panel’s interpretation of the evidence, Canada is a highly innovative nation, but significant barriers prevent the translation of innovation into wealth creation. The available evidence does point to a number of important contributing factors that are analyzed in this report. Figure 5 represents the relationships between R&D, innovation, and wealth creation.

The Panel concluded that many factors commonly identified as points of concern do not adequately explain the overall weakness in Canada’s innovation performance compared with other countries. [emphasis mine] Academia-business linkages appear relatively robust in quantitative terms given the extent of cross-sectoral R&D funding and increasing academia-industry partnerships, though the volume of academia-industry interactions does not indicate the nature or the quality of that interaction, nor the extent to which firms are capitalizing on the research conducted and the resulting IP. The educational system is high performing by international standards and there does not appear to be a widespread lack of researchers or STEM (science, technology, engineering, and mathematics) skills. IP policies differ across universities and are unlikely to explain a divergence in research commercialization activity between Canadian and U.S. institutions, though Canadian universities and governments could do more to help Canadian firms access university IP and compete in IP management and strategy. Venture capital availability in Canada has improved dramatically in recent years and is now competitive internationally, though still overshadowed by Silicon Valley. Technology start-ups and start-up ecosystems are also flourishing in many sectors and regions, demonstrating their ability to build on research advances to develop and deliver innovative products and services.

You’ll note there’s no mention of a cultural issue where start-ups are designed for sale as soon as possible and this isn’t new. Years ago, there was an accounting firm that published a series of historical maps (the last one I saw was in 2005) of technology companies in the Vancouver region. Technology companies were being developed and sold to large foreign companies from the 19th century to present day.

Robotics where and how you don’t expect them: a wearable robot and a robot implant for regeneration

Generally I  expect robots to be machines that are external to my body but recently there were two news bits about some different approaches. First, the wearable robot.

A robot that supports your hip

A January 10, 2018 news item on ScienceDaily describes research into muscles that can be worn,

Scientists are one step closer to artificial muscles. Orthotics have come a long way since their initial wood and strap designs, yet innovation lapsed when it came to compensating for muscle power — until now.

A collaborative research team has designed a wearable robot to support a person’s hip joint while walking. The team, led by Minoru Hashimoto, a professor of textile science and technology at Shinshu University in Japan, published the details of their prototype in Smart Materials and Structures, a journal published by the Institute of Physics.

A January 9, 2018 Shinshu University press release on EurekAlert, which originated the news item, provides more detail,

“With a rapidly aging society, an increasing number of elderly people require care after suffering from stroke, and other-age related disabilities. Various technologies, devices, and robots are emerging to aid caretakers,” wrote Hashimoto, noting that several technologies meant to assist a person with walking are often cumbersome to the user. “[In our] current study, [we] sought to develop a lightweight, soft, wearable assist wear for supporting activities of daily life for older people with weakened muscles and those with mobility issues.”

The wearable system consists of plasticized polyvinyl chloride (PVC) gel, mesh electrodes, and applied voltage. The mesh electrodes sandwich the gel, and when voltage is applied, the gel flexes and contracts, like a muscle. It’s a wearable actuator, the mechanism that causes movement.

“We thought that the electrical mechanical properties of the PVC gel could be used for robotic artificial muscles, so we started researching the PVC gel,” said Hashimoto. “The ability to add voltage to PVC gel is especially attractive for high speed movement, and the gel moves with high speed with just a few hundred volts.”

In a preliminary evaluation, a stroke patient with some paralysis on one side of his body walked with and without the wearable system.

“We found that the assist wear enabled natural movement, increasing step length and decreasing muscular activity during straight line walking,” wrote Hashimoto. The researchers also found that adjusting the charge could change the level of assistance the actuator provides.

The robotic system earned first place in demonstrations with their multilayer PVC gel artificial muscle at the, “24th International Symposium on Smart Structures and Materials & Nondestructive Evaluation and Health Monitoring” for SPIE the international society for optics and photonics.

Next, the researchers plan to create a string actuator using the PVC gel, which could potentially lead to the development of fabric capable of providing more manageable external muscular support with ease.

This paper is behind a paywall and I see it was published in the Fall of 2017. Either they postponed the publicity or this is the second wave. In any event, it was timely as it allowed me to post this along with the robotic research on regeneration.

Robotic implants and tissue regeneration

Boston Children’s Hospital in a January 10, 2018 news release on EurekAlert describes a new (to me) method for tissue regeneration,

An implanted, programmable medical robot can gradually lengthen tubular organs by applying traction forces — stimulating tissue growth in stunted organs without interfering with organ function or causing apparent discomfort, report researchers at Boston Children’s Hospital.

The robotic system, described today in Science Robotics, induced cell proliferation and lengthened part of the esophagus in a large animal by about 75 percent, while the animal remained awake and mobile. The researchers say the system could treat long-gap esophageal atresia, a rare birth defect in which part of the esophagus is missing, and could also be used to lengthen the small intestine in short bowel syndrome.

The most effective current operation for long-gap esophageal atresia, called the Foker process, uses sutures anchored on the patient’s back to gradually pull on the esophagus. To prevent the esophagus from tearing, patients must be paralyzed in a medically induced coma and placed on mechanical ventilation in the intensive care unit for one to four weeks. The long period of immobilization can also cause medical complications such as bone fractures and blood clots.

“This project demonstrates proof-of-concept that miniature robots can induce organ growth inside a living being for repair or replacement, while avoiding the sedation and paralysis currently required for the most difficult cases of esophageal atresia,” says Russell Jennings, MD, surgical director of the Esophageal and Airway Treatment Center at Boston Children’s Hospital, and a co-investigator on the study. “The potential uses of such robots are yet to be fully explored, but they will certainly be applied to many organs in the near future.”

The motorized robotic device is attached only to the esophagus, so would allow a patient to move freely. Covered by a smooth, biocompatible, waterproof “skin,” it includes two attachment rings, placed around the esophagus and sewn into place with sutures. A programmable control unit outside the body applies adjustable traction forces to the rings, slowly and steadily pulling the tissue in the desired direction.

The device was tested in the esophagi of pigs (five received the implant and three served as controls). The distance between the two rings (pulling the esophagus in opposite directions) was increased by small, 2.5-millimeter increments each day for 8 to 9 days. The animals were able to eat normally even with the device applying traction to its esophagus, and showed no sign of discomfort.

On day 10, the segment of esophagus had increased in length by 77 percent on average. Examination of the tissue showed a proliferation of the cells that make up the esophagus. The organ also maintained its normal diameter.

“This shows we didn’t simply stretch the esophagus — it lengthened through cell growth,” says Pierre Dupont, PhD, the study’s senior investigator and Chief of Pediatric Cardiac Bioengineering at Boston Children’s.

The research team is now starting to test the robotic system in a large animal model of short bowel syndrome. While long-gap esophageal atresia is quite rare, the prevalence of short bowel syndrome is much higher. Short bowel can be caused by necrotizing enterocolitis in the newborn, Crohn’s disease in adults, or a serious infection or cancer requiring a large segment of intestine to be removed.

“Short bowel syndrome is a devastating illness requiring patients to be fed intravenously,” says gastroenterologist Peter Ngo, MD, a coauthor on the study. “This, in turn, can lead to liver failure, sometimes requiring a liver or multivisceral (liver-intestine) transplant, outcomes that are both devastating and costly.”

The team hopes to get support to continue its tests of the device in large animal models, and eventually conduct clinical trials. They will also test other features.

“No one knows the best amount of force to apply to an organ to induce growth,” explains Dupont. “Today, in fact, we don’t even know what forces we are applying clinically. It’s all based on surgeon experience. A robotic device can figure out the best forces to apply and then apply those forces precisely.”

Nano-neurons from a French-Japanese-US research team

This news about nano-neurons comes from a Nov. 8, 2017 news item on defenceweb.co.za,

Researchers from the Joint Physics Unit CNRS/Thales, the Nanosciences and Nanotechnologies Centre (CNRS/Université Paris Sud), in collaboration with American and Japanese researchers, have developed the world’s first artificial nano-neuron with the ability to recognise numbers spoken by different individuals. Just like the recent development of electronic synapses described in a Nature article, this electronic nano-neuron is a breakthrough in artificial intelligence and its potential applications.

A Sept. 19, 2017 Thales press release, which originated the news item, expands on the theme,

The latest artificial intelligence algorithms are able to recognise visual and vocal cues with high levels of performance. But running these programs on conventional computers uses 10,000 times more energy than the human brain. To reduce electricity consumption, a new type of computer is needed. It is inspired by the human brain and comprises vast numbers of miniaturised neurons and synapses. Until now, however, it had not been possible to produce a stable enough artificial nano-neuron which would process the information reliably.

Today [Sept. 19, 2017 or July 27, 2017 when the paper was published in Nature?]], for the first time, researchers have developed a nano-neuron with the ability to recognise numbers spoken by different individuals with 99.6% accuracy. This breakthrough relied on the use of an exceptionally stable magnetic oscillator. Each gyration of this nano-compass generates an electrical output, which effectively imitates the electrical impulses produced by biological neurons. In the next few years, these magnetic nano-neurons could be interconnected via artificial synapses, such as those recently developed, for real-time big data analytics and classification.

The project is a collaborative initiative between fundamental research laboratories and applied research partners. The long-term goal is to produce extremely energy-efficient miniaturised chips with the intelligence needed to learn from and adapt to the constantly ever-changing and ambiguous situations of the real world. These electronic chips will have many practical applications, such as providing smart guidance to robots or autonomous vehicles, helping doctors in their diagnosis’ and improving medical prostheses. This project included researchers from the Joint Physics Unit CNRS/Thales, the AIST, the CNS-NIST, and the Nanosciences and Nanotechnologies Centre (CNRS/Université Paris-Sud).

Alberta adds a newish quantum nanotechnology research hub to the Canada’s quantum computing research scene

One of the winners in Canada’s 2017 federal budget announcement of the Pan-Canadian Artificial Intelligence Strategy was Edmonton, Alberta. It’s a fact which sometimes goes unnoticed while Canadians marvel at the wonderfulness found in Toronto and Montréal where it seems new initiatives and monies are being announced on a weekly basis (I exaggerate) for their AI (artificial intelligence) efforts.

Alberta’s quantum nanotechnology hub (graduate programme)

Intriguingly, it seems that Edmonton has higher aims than (an almost unnoticed) leadership in AI. Physicists at the University of Alberta have announced hopes to be just as successful as their AI brethren in a Nov. 27, 2017 article by Juris Graney for the Edmonton Journal,

Physicists at the University of Alberta [U of A] are hoping to emulate the success of their artificial intelligence studying counterparts in establishing the city and the province as the nucleus of quantum nanotechnology research in Canada and North America.

Google’s artificial intelligence research division DeepMind announced in July [2017] it had chosen Edmonton as its first international AI research lab, based on a long-running partnership with the U of A’s 10-person AI lab.

Retaining the brightest minds in the AI and machine-learning fields while enticing a global tech leader to Alberta was heralded as a coup for the province and the university.

It is something U of A physics professor John Davis believes the university’s new graduate program, Quanta, can help achieve in the world of quantum nanotechnology.

The field of quantum mechanics had long been a realm of theoretical science based on the theory that atomic and subatomic material like photons or electrons behave both as particles and waves.

“When you get right down to it, everything has both behaviours (particle and wave) and we can pick and choose certain scenarios which one of those properties we want to use,” he said.

But, Davis said, physicists and scientists are “now at the point where we understand quantum physics and are developing quantum technology to take to the marketplace.”

“Quantum computing used to be realm of science fiction, but now we’ve figured it out, it’s now a matter of engineering,” he said.

Quantum computing labs are being bought by large tech companies such as Google, IBM and Microsoft because they realize they are only a few years away from having this power, he said.

Those making the groundbreaking developments may want to commercialize their finds and take the technology to market and that is where Quanta comes in.

East vs. West—Again?

Ivan Semeniuk in his article, Quantum Supremacy, ignores any quantum research effort not located in either Waterloo, Ontario or metro Vancouver, British Columbia to describe a struggle between the East and the West (a standard Canadian trope). From Semeniuk’s Oct. 17, 2017 quantum article [link follows the excerpts] for the Globe and Mail’s October 2017 issue of the Report on Business (ROB),

 Lazaridis [Mike], of course, has experienced lost advantage first-hand. As co-founder and former co-CEO of Research in Motion (RIM, now called Blackberry), he made the smartphone an indispensable feature of the modern world, only to watch rivals such as Apple and Samsung wrest away Blackberry’s dominance. Now, at 56, he is engaged in a high-stakes race that will determine who will lead the next technology revolution. In the rolling heartland of southwestern Ontario, he is laying the foundation for what he envisions as a new Silicon Valley—a commercial hub based on the promise of quantum technology.

Semeniuk skips over the story of how Blackberry lost its advantage. I came onto that story late in the game when Blackberry was already in serious trouble due to a failure to recognize that the field they helped to create was moving in a new direction. If memory serves, they were trying to keep their technology wholly proprietary which meant that developers couldn’t easily create apps to extend the phone’s features. Blackberry also fought a legal battle in the US with a patent troll draining company resources and energy in proved to be a futile effort.

Since then Lazaridis has invested heavily in quantum research. He gave the University of Waterloo a serious chunk of money as they named their Quantum Nano Centre (QNC) after him and his wife, Ophelia (you can read all about it in my Sept. 25, 2012 posting about the then new centre). The best details for Lazaridis’ investments in Canada’s quantum technology are to be found on the Quantum Valley Investments, About QVI, History webpage,

History-bannerHistory has repeatedly demonstrated the power of research in physics to transform society.  As a student of history and a believer in the power of physics, Mike Lazaridis set out in 2000 to make real his bold vision to establish the Region of Waterloo as a world leading centre for physics research.  That is, a place where the best researchers in the world would come to do cutting-edge research and to collaborate with each other and in so doing, achieve transformative discoveries that would lead to the commercialization of breakthrough  technologies.

Establishing a World Class Centre in Quantum Research:

The first step in this regard was the establishment of the Perimeter Institute for Theoretical Physics.  Perimeter was established in 2000 as an independent theoretical physics research institute.  Mike started Perimeter with an initial pledge of $100 million (which at the time was approximately one third of his net worth).  Since that time, Mike and his family have donated a total of more than $170 million to the Perimeter Institute.  In addition to this unprecedented monetary support, Mike also devotes his time and influence to help lead and support the organization in everything from the raising of funds with government and private donors to helping to attract the top researchers from around the globe to it.  Mike’s efforts helped Perimeter achieve and grow its position as one of a handful of leading centres globally for theoretical research in fundamental physics.

Stephen HawkingPerimeter is located in a Governor-General award winning designed building in Waterloo.  Success in recruiting and resulting space requirements led to an expansion of the Perimeter facility.  A uniquely designed addition, which has been described as space-ship-like, was opened in 2011 as the Stephen Hawking Centre in recognition of one of the most famous physicists alive today who holds the position of Distinguished Visiting Research Chair at Perimeter and is a strong friend and supporter of the organization.

Recognizing the need for collaboration between theorists and experimentalists, in 2002, Mike applied his passion and his financial resources toward the establishment of The Institute for Quantum Computing at the University of Waterloo.  IQC was established as an experimental research institute focusing on quantum information.  Mike established IQC with an initial donation of $33.3 million.  Since that time, Mike and his family have donated a total of more than $120 million to the University of Waterloo for IQC and other related science initiatives.  As in the case of the Perimeter Institute, Mike devotes considerable time and influence to help lead and support IQC in fundraising and recruiting efforts.  Mike’s efforts have helped IQC become one of the top experimental physics research institutes in the world.

Quantum ComputingMike and Doug Fregin have been close friends since grade 5.  They are also co-founders of BlackBerry (formerly Research In Motion Limited).  Doug shares Mike’s passion for physics and supported Mike’s efforts at the Perimeter Institute with an initial gift of $10 million.  Since that time Doug has donated a total of $30 million to Perimeter Institute.  Separately, Doug helped establish the Waterloo Institute for Nanotechnology at the University of Waterloo with total gifts for $29 million.  As suggested by its name, WIN is devoted to research in the area of nanotechnology.  It has established as an area of primary focus the intersection of nanotechnology and quantum physics.

With a donation of $50 million from Mike which was matched by both the Government of Canada and the province of Ontario as well as a donation of $10 million from Doug, the University of Waterloo built the Mike & Ophelia Lazaridis Quantum-Nano Centre, a state of the art laboratory located on the main campus of the University of Waterloo that rivals the best facilities in the world.  QNC was opened in September 2012 and houses researchers from both IQC and WIN.

Leading the Establishment of Commercialization Culture for Quantum Technologies in Canada:

In the Research LabFor many years, theorists have been able to demonstrate the transformative powers of quantum mechanics on paper.  That said, converting these theories to experimentally demonstrable discoveries has, putting it mildly, been a challenge.  Many naysayers have suggested that achieving these discoveries was not possible and even the believers suggested that it could likely take decades to achieve these discoveries.  Recently, a buzz has been developing globally as experimentalists have been able to achieve demonstrable success with respect to Quantum Information based discoveries.  Local experimentalists are very much playing a leading role in this regard.  It is believed by many that breakthrough discoveries that will lead to commercialization opportunities may be achieved in the next few years and certainly within the next decade.

Recognizing the unique challenges for the commercialization of quantum technologies (including risk associated with uncertainty of success, complexity of the underlying science and high capital / equipment costs) Mike and Doug have chosen to once again lead by example.  The Quantum Valley Investment Fund will provide commercialization funding, expertise and support for researchers that develop breakthroughs in Quantum Information Science that can reasonably lead to new commercializable technologies and applications.  Their goal in establishing this Fund is to lead in the development of a commercialization infrastructure and culture for Quantum discoveries in Canada and thereby enable such discoveries to remain here.

Semeniuk goes on to set the stage for Waterloo/Lazaridis vs. Vancouver (from Semeniuk’s 2017 ROB article),

… as happened with Blackberry, the world is once again catching up. While Canada’s funding of quantum technology ranks among the top five in the world, the European Union, China, and the US are all accelerating their investments in the field. Tech giants such as Google [also known as Alphabet], Microsoft and IBM are ramping up programs to develop companies and other technologies based on quantum principles. Meanwhile, even as Lazaridis works to establish Waterloo as the country’s quantum hub, a Vancouver-area company has emerged to challenge that claim. The two camps—one methodically focused on the long game, the other keen to stake an early commercial lead—have sparked an East-West rivalry that many observers of the Canadian quantum scene are at a loss to explain.

Is it possible that some of the rivalry might be due to an influential individual who has invested heavily in a ‘quantum valley’ and has a history of trying to ‘own’ a technology?

Getting back to D-Wave Systems, the Vancouver company, I have written about them a number of times (particularly in 2015; for the full list: input D-Wave into the blog search engine). This June 26, 2015 posting includes a reference to an article in The Economist magazine about D-Wave’s commercial opportunities while the bulk of the posting is focused on a technical breakthrough.

Semeniuk offers an overview of the D-Wave Systems story,

D-Wave was born in 1999, the same year Lazaridis began to fund quantum science in Waterloo. From the start, D-Wave had a more immediate goal: to develop a new computer technology to bring to market. “We didn’t have money or facilities,” says Geordie Rose, a physics PhD who co0founded the company and served in various executive roles. …

The group soon concluded that the kind of machine most scientists were pursing based on so-called gate-model architecture was decades away from being realized—if ever. …

Instead, D-Wave pursued another idea, based on a principle dubbed “quantum annealing.” This approach seemed more likely to produce a working system, even if the application that would run on it were more limited. “The only thing we cared about was building the machine,” says Rose. “Nobody else was trying to solve the same problem.”

D-Wave debuted its first prototype at an event in California in February 2007 running it through a few basic problems such as solving a Sudoku puzzle and finding the optimal seating plan for a wedding reception. … “They just assumed we were hucksters,” says Hilton [Jeremy Hilton, D.Wave senior vice-president of systems]. Federico Spedalieri, a computer scientist at the University of Southern California’s [USC} Information Sciences Institute who has worked with D-Wave’s system, says the limited information the company provided about the machine’s operation provoked outright hostility. “I think that played against them a lot in the following years,” he says.

It seems Lazaridis is not the only one who likes to hold company information tightly.

Back to Semeniuk and D-Wave,

Today [October 2017], the Los Alamos National Laboratory owns a D-Wave machine, which costs about $15million. Others pay to access D-Wave systems remotely. This year , for example, Volkswagen fed data from thousands of Beijing taxis into a machine located in Burnaby [one of the municipalities that make up metro Vancouver] to study ways to optimize traffic flow.

But the application for which D-Wave has the hights hope is artificial intelligence. Any AI program hings on the on the “training” through which a computer acquires automated competence, and the 2000Q [a D-Wave computer] appears well suited to this task. …

Yet, for all the buzz D-Wave has generated, with several research teams outside Canada investigating its quantum annealing approach, the company has elicited little interest from the Waterloo hub. As a result, what might seem like a natural development—the Institute for Quantum Computing acquiring access to a D-Wave machine to explore and potentially improve its value—has not occurred. …

I am particularly interested in this comment as it concerns public funding (from Semeniuk’s article),

Vern Brownell, a former Goldman Sachs executive who became CEO of D-Wave in 2009, calls the lack of collaboration with Waterloo’s research community “ridiculous,” adding that his company’s efforts to establish closer ties have proven futile, “I’ll be blunt: I don’t think our relationship is good enough,” he says. Brownell also point out that, while  hundreds of millions in public funds have flowed into Waterloo’s ecosystem, little funding is available for  Canadian scientists wishing to make the most of D-Wave’s hardware—despite the fact that it remains unclear which core quantum technology will prove the most profitable.

There’s a lot more to Semeniuk’s article but this is the last excerpt,

The world isn’t waiting for Canada’s quantum rivals to forge a united front. Google, Microsoft, IBM, and Intel are racing to develop a gate-model quantum computer—the sector’s ultimate goal. (Google’s researchers have said they will unveil a significant development early next year.) With the U.K., Australia and Japan pouring money into quantum, Canada, an early leader, is under pressure to keep up. The federal government is currently developing  a strategy for supporting the country’s evolving quantum sector and, ultimately, getting a return on its approximately $1-billion investment over the past decade [emphasis mine].

I wonder where the “approximately $1-billion … ” figure came from. I ask because some years ago MP Peter Julian asked the government for information about how much Canadian federal money had been invested in nanotechnology. The government replied with sheets of paper (a pile approximately 2 inches high) that had funding disbursements from various ministries. Each ministry had its own method with different categories for listing disbursements and the titles for the research projects were not necessarily informative for anyone outside a narrow specialty. (Peter Julian’s assistant had kindly sent me a copy of the response they had received.) The bottom line is that it would have been close to impossible to determine the amount of federal funding devoted to nanotechnology using that data. So, where did the $1-billion figure come from?

In any event, it will be interesting to see how the Council of Canadian Academies assesses the ‘quantum’ situation in its more academically inclined, “The State of Science and Technology and Industrial Research and Development in Canada,” when it’s released later this year (2018).

Finally, you can find Semeniuk’s October 2017 article here but be aware it’s behind a paywall.

Whither we goest?

Despite any doubts one might have about Lazaridis’ approach to research and technology, his tremendous investment and support cannot be denied. Without him, Canada’s quantum research efforts would be substantially less significant. As for the ‘cowboys’ in Vancouver, it takes a certain temperament to found a start-up company and it seems the D-Wave folks have more in common with Lazaridis than they might like to admit. As for the Quanta graduate  programme, it’s early days yet and no one should ever count out Alberta.

Meanwhile, one can continue to hope that a more thoughtful approach to regional collaboration will be adopted so Canada can continue to blaze trails in the field of quantum research.

CRISPR-CAS9 and gold

As so often happens in the sciences, now that the initial euphoria has expended itself problems (and solutions) with CRISPR ((clustered regularly interspaced short palindromic repeats))-CAAS9 are being disclosed to those of us who are not experts. From an Oct. 3, 2017 article by Bob Yirka for phys.org,

A team of researchers from the University of California and the University of Tokyo has found a way to use the CRISPR gene editing technique that does not rely on a virus for delivery. In their paper published in the journal Nature Biomedical Engineering, the group describes the new technique, how well it works and improvements that need to be made to make it a viable gene editing tool.

CRISPR-Cas9 has been in the news a lot lately because it allows researchers to directly edit genes—either disabling unwanted parts or replacing them altogether. But despite many success stories, the technique still suffers from a major deficit that prevents it from being used as a true medical tool—it sometimes makes mistakes. Those mistakes can cause small or big problems for a host depending on what goes wrong. Prior research has suggested that the majority of mistakes are due to delivery problems, which means that a replacement for the virus part of the technique is required. In this new effort, the researchers report that they have discovered just a such a replacement, and it worked so well that it was able to repair a gene mutation in a Duchenne muscular dystrophy mouse model. The team has named the new technique CRISPR-Gold, because a gold nanoparticle was used to deliver the gene editing molecules instead of a virus.

An Oct. 2, 2017 article by Abby Olena for The Scientist lays out the CRISPR-CAS9 problems the scientists are trying to solve (Note: Links have been removed),

While promising, applications of CRISPR-Cas9 gene editing have so far been limited by the challenges of delivery—namely, how to get all the CRISPR parts to every cell that needs them. In a study published today (October 2) in Nature Biomedical Engineering, researchers have successfully repaired a mutation in the gene for dystrophin in a mouse model of Duchenne muscular dystrophy by injecting a vehicle they call CRISPR-Gold, which contains the Cas9 protein, guide RNA, and donor DNA, all wrapped around a tiny gold ball.

The authors have made “great progress in the gene editing area,” says Tufts University biomedical engineer Qiaobing Xu, who did not participate in the work but penned an accompanying commentary. Because their approach is nonviral, Xu explains, it will minimize the potential off-target effects that result from constant Cas9 activity, which occurs when users deliver the Cas9 template with a viral vector.

Duchenne muscular dystrophy is a degenerative disease of the muscles caused by a lack of the protein dystrophin. In about a third of patients, the gene for dystrophin has small deletions or single base mutations that render it nonfunctional, which makes this gene an excellent candidate for gene editing. Researchers have previously used viral delivery of CRISPR-Cas9 components to delete the mutated exon and achieve clinical improvements in mouse models of the disease.

“In this paper, we were actually able to correct [the gene for] dystrophin back to the wild-type sequence” via homology-directed repair (HDR), coauthor Niren Murthy, a drug delivery researcher at the University of California, Berkeley, tells The Scientist. “The other way of treating this is to do something called exon skipping, which is where you delete some of the exons and you can get dystrophin to be produced, but it’s not [as functional as] the wild-type protein.”

The research team created CRISPR-Gold by covering a central gold nanoparticle with DNA that they modified so it would stick to the particle. This gold-conjugated DNA bound the donor DNA needed for HDR, which the Cas9 protein and guide RNA bound to in turn. They coated the entire complex with a polymer that seems to trigger endocytosis and then facilitate escape of the Cas9 protein, guide RNA, and template DNA from endosomes within cells.

In order to do HDR, “you have to provide the cell [with] the Cas9 enzyme, guide RNA by which you target Cas9 to a particular part of the genome, and a big chunk of DNA, which will be used as a template to edit the mutant sequence to wild-type,” explains coauthor Irina Conboy, who studies tissue repair at the University of California, Berkeley. “They all have to be present at the same time and at the same place, so in our system you have a nanoparticle which simultaneously delivers all of those three key components in their active state.”

Olena’s article carries on to describe how the team created CRISPR-Gold and more.

Additional technical details are available in an Oct. 3, 2017 University of California at Berkeley news release by Brett Israel (also on EurekAlert), which originated the news item (Note: A link has been removed) ,

Scientists at the University of California, Berkeley, have engineered a new way to deliver CRISPR-Cas9 gene-editing technology inside cells and have demonstrated in mice that the technology can repair the mutation that causes Duchenne muscular dystrophy, a severe muscle-wasting disease. A new study shows that a single injection of CRISPR-Gold, as the new delivery system is called, into mice with Duchenne muscular dystrophy led to an 18-times-higher correction rate and a two-fold increase in a strength and agility test compared to control groups.

CRISPR–Gold is composed of 15 nanometer gold nanoparticles that are conjugated to thiol-modified oligonucleotides (DNA-Thiol), which are hybridized with single-stranded donor DNA and subsequently complexed with Cas9 and encapsulated by a polymer that disrupts the endosome of the cell.

Since 2012, when study co-author Jennifer Doudna, a professor of molecular and cell biology and of chemistry at UC Berkeley, and colleague Emmanuelle Charpentier, of the Max Planck Institute for Infection Biology, repurposed the Cas9 protein to create a cheap, precise and easy-to-use gene editor, researchers have hoped that therapies based on CRISPR-Cas9 would one day revolutionize the treatment of genetic diseases. Yet developing treatments for genetic diseases remains a big challenge in medicine. This is because most genetic diseases can be cured only if the disease-causing gene mutation is corrected back to the normal sequence, and this is impossible to do with conventional therapeutics.

CRISPR/Cas9, however, can correct gene mutations by cutting the mutated DNA and triggering homology-directed DNA repair. However, strategies for safely delivering the necessary components (Cas9, guide RNA that directs Cas9 to a specific gene, and donor DNA) into cells need to be developed before the potential of CRISPR-Cas9-based therapeutics can be realized. A common technique to deliver CRISPR-Cas9 into cells employs viruses, but that technique has a number of complications. CRISPR-Gold does not need viruses.

In the new study, research lead by the laboratories of Berkeley bioengineering professors Niren Murthy and Irina Conboy demonstrated that their novel approach, called CRISPR-Gold because gold nanoparticles are a key component, can deliver Cas9 – the protein that binds and cuts DNA – along with guide RNA and donor DNA into the cells of a living organism to fix a gene mutation.

“CRISPR-Gold is the first example of a delivery vehicle that can deliver all of the CRISPR components needed to correct gene mutations, without the use of viruses,” Murthy said.

The study was published October 2 [2017] in the journal Nature Biomedical Engineering.

CRISPR-Gold repairs DNA mutations through a process called homology-directed repair. Scientists have struggled to develop homology-directed repair-based therapeutics because they require activity at the same place and time as Cas9 protein, an RNA guide that recognizes the mutation and donor DNA to correct the mutation.

To overcome these challenges, the Berkeley scientists invented a delivery vessel that binds all of these components together, and then releases them when the vessel is inside a wide variety of cell types, triggering homology directed repair. CRISPR-Gold’s gold nanoparticles coat the donor DNA and also bind Cas9. When injected into mice, their cells recognize a marker in CRISPR-Gold and then import the delivery vessel. Then, through a series of cellular mechanisms, CRISPR-Gold is released into the cells’ cytoplasm and breaks apart, rapidly releasing Cas9 and donor DNA.

A single injection of CRISPR-Gold into muscle tissue of mice that model Duchenne muscular dystrophy restored 5.4 percent of the dystrophin gene, which causes the disease, to the wild- type, or normal, sequence. This correction rate was approximately 18 times higher than in mice treated with Cas9 and donor DNA by themselves, which experienced only a 0.3 percent correction rate.

Importantly, the study authors note, CRISPR-Gold faithfully restored the normal sequence of dystrophin, which is a significant improvement over previously published approaches that only removed the faulty part of the gene, making it shorter and converting one disease into another, milder disease.

CRISPR-Gold was also able to reduce tissue fibrosis – the hallmark of diseases where muscles do not function properly – and enhanced strength and agility in mice with Duchenne muscular dystrophy. CRISPR-Gold-treated mice showed a two-fold increase in hanging time in a common test for mouse strength and agility, compared to mice injected with a control.

“These experiments suggest that it will be possible to develop non-viral CRISPR therapeutics that can safely correct gene mutations, via the process of homology-directed repair, by simply developing nanoparticles that can simultaneously encapsulate all of the CRISPR components,” Murthy said.

The study found that CRISPR-Gold’s approach to Cas9 protein delivery is safer than viral delivery of CRISPR, which, in addition to toxicity, amplifies the side effects of Cas9 through continuous expression of this DNA-cutting enzyme. When the research team tested CRISPR-Gold’s gene-editing capability in mice, they found that CRISPR-Gold efficiently corrected the DNA mutation that causes Duchenne muscular dystrophy, with minimal collateral DNA damage.

The researchers quantified CRISPR-Gold’s off-target DNA damage and found damage levels similar to the that of a typical DNA sequencing error in a typical cell that was not exposed to CRISPR (0.005 – 0.2 percent). To test for possible immunogenicity, the blood stream cytokine profiles of mice were analyzed at 24 hours and two weeks after the CRISPR-Gold injection. CRISPR-Gold did not cause an acute up-regulation of inflammatory cytokines in plasma, after multiple injections, or weight loss, suggesting that CRISPR-Gold can be used multiple times safely, and that it has a high therapeutic window for gene editing in muscle tissue.

“CRISPR-Gold and, more broadly, CRISPR-nanoparticles open a new way for safer, accurately controlled delivery of gene-editing tools,” Conboy said. “Ultimately, these techniques could be developed into a new medicine for Duchenne muscular dystrophy and a number of other genetic diseases.”

A clinical trial will be needed to discern whether CRISPR-Gold is an effective treatment for genetic diseases in humans. Study co-authors Kunwoo Lee and Hyo Min Park have formed a start-up company, GenEdit (Murthy has an ownership stake in GenEdit), which is focused on translating the CRISPR-Gold technology into humans. The labs of Murthy and Conboy are also working on the next generation of particles that can deliver CRISPR into tissues from the blood stream and would preferentially target adult stem cells, which are considered the best targets for gene correction because stem and progenitor cells are capable of gene editing, self-renewal and differentiation.

“Genetic diseases cause devastating levels of mortality and morbidity, and new strategies for treating them are greatly needed,” Murthy said. “CRISPR-Gold was able to correct disease-causing gene mutations in vivo, via the non-viral delivery of Cas9 protein, guide RNA and donor DNA, and therefore has the potential to develop into a therapeutic for treating genetic diseases.”

The study was funded by the National Institutes of Health, the W.M. Keck Foundation, the Moore Foundation, the Li Ka Shing Foundation, Calico, Packer, Roger’s and SENS, and the Center of Innovation (COI) Program of the Japan Science and Technology Agency.

Cleaning up disasters with Hokusai’s blue and cellulose nanofibers to clean up contaminated soil and water in Fukushima

The Great Wave off Kanagawa (Under a wave off Kanagawa”), also known as The Great Wave or simply The Wave, by Katsushika Hokusai – Metropolitan Museum of Art, online database: entry 45434, Public Domain, https://commons.wikimedia.org/w/index.php?curid=2798407

I thought it might be a good idea to embed a copy of Hokusai’s Great Wave and the blue these scientists in Japan have used as their inspiration. (By the way, it seems these scientists collaborated with Mildred Dresselhaus who died at the age of 86, a few months after their paper was published. In honour of he and before the latest, here’s my Feb. 23, 2017 posting about the ‘Queen of Carbon’.)

Now onto more current news, from an Oct. 13, 2017 news item on Nanowerk (Note: A link has been removed),

By combining the same Prussian blue pigment used in the works of popular Edo-period artist Hokusai and cellulose nanofiber, a raw material of paper, a University of Tokyo research team succeeded in synthesizing compound nanoparticles, comprising organic and inorganic substances (Scientific Reports, “Cellulose nanofiber backboned Prussian blue nanoparticles as powerful adsorbents for the selective elimination of radioactive cesium”). This new class of organic/inorganic composite nanoparticles is able to selectively adsorb, or collect on the surface, radioactive cesium.

The team subsequently developed sponges from these nanoparticles that proved highly effective in decontaminating the water and soil in Fukushima Prefecture exposed to radioactivity following the nuclear accident there in March 2011.

I think these are the actual sponges not an artist’s impression,

An Oct. 13, 2017 University of Tokyo press release, which originated the news item, provides more detail about the sponges and the difficulties of remediating radioactive air and soil,

Removing radioactive materials such as cesium-134 and -137 from contaminated seawater or soil is not an easy job. First of all, a huge amount of similar substances with competing functions has to be removed from the area, an extremely difficult task. Prussian blue (ferric hexacyanoferrate) has a jungle gym-like colloidal structure, and the size of its single cubic orifice, or opening, is a near-perfect match to the size of cesium ions; therefore, it is prescribed as medication for patients exposed to radiation for selectively adsorbing cesium. However, as Prussian blue is highly attracted to water, recovering it becomes highly difficult once it is dissolved into the environment; for this reason, its use in the field for decontamination has been limited.

Taking a hint from the Prussian blue in Hokusai’s woodblock prints not losing their color even when getting wet from rain, the team led by Professor Ichiro Sakata and Project Professor Bunshi Fugetsu at the University of Tokyo’s Nanotechnology Innovation Research Unit at the Policy Alternatives Research Institute, and Project Researcher Adavan Kiliyankil Vipin at the Graduate School of Engineering developed an insoluble nanoparticle obtained from combining cellulose and Prussian blue—Hokusai had in fact formed a chemical bond in his handling of Prussian blue and paper (cellulose).

The scientists created this cellulose-Prussian blue combined nanoparticle by first preparing cellulose nanofibers using a process called TEMPO oxidization and securing ferric ions (III) onto them, then introduced a certain amount of hexacyanoferrate, which adhered to Prussian blue nanoparticles with a diameter ranging from 5–10 nanometers. The nanoparticles obtained in this way were highly resistant to water, and moreover, were capable of adsorbing 139 mg of radioactive cesium ion per gram.

Field studies on soil decontamination in Fukushima have been underway since last year. A highly effective approach has been to sow and allow plant seeds to germinate inside the sponge made from the nanoparticles, then getting the plants’ roots to take up cesium ions from the soil to the sponge. Water can significantly shorten decontamination times compared to soil, which usually requires extracting cesium from it with a solvent.

It has been more than six years since the radioactive fallout from a series of accidents at the Fukushima Daiichi nuclear power plant following the giant earthquake and tsunami in northeastern Japan. Decontamination with the cellulose nanofiber-Prussian blue compound can lead to new solutions for contamination in disaster-stricken areas.

“I was pondering about how Prussian blue immediately gets dissolved in water when I happened upon a Hokusai woodblock print, and how the indigo color remained firmly set in the paper, without bleeding, even after all these years,” reflects Fugetsu. He continues, “That revelation provided a clue for a solution.”

“The amount of research on cesium decontamination increased after the Chernobyl nuclear power plant accident, but a lot of the studies were limited to being academic and insufficient for practical application in Fukushima,” says Vipin. He adds, “Our research offers practical applications and has high potential for decontamination on an industrial scale not only in Fukushima but also in other cesium-contaminated areas.”

(Merry Christmas!) Japanese tree frogs inspire hardware for the highest of tech: a swarmalator

First, the frog,

[Japanese Tree Frog] By 池田正樹 (talk)masaki ikeda – Own work, Public Domain, https://commons.wikimedia.org/w/index.php?curid=4593224

I wish they had a recording of the mating calls for Japanese tree frogs since they were the inspiration for mathematicians at Cornell University (New York state, US) according to a November 17, 2017 news item on ScienceDaily,

How does the Japanese tree frog figure into the latest work of noted mathematician Steven Strogatz? As it turns out, quite prominently.

“We had read about these funny frogs that hop around and croak,” said Strogatz, the Jacob Gould Schurman Professor of Applied Mathematics. “They form patterns in space and time. Usually it’s about reproduction. And based on how the other guy or guys are croaking, they don’t want to be around another one that’s croaking at the same time as they are, because they’ll jam each other.”

A November 15, 2017 Cornell University news release (also on EurekAlert but dated November 17, 2017) by Tom Fleischman, which originated the news item, details how the calls led to ‘swarmalators’ (Note: Links have been removed),

Strogatz and Kevin O’Keeffe, Ph.D. ’17, used the curious mating ritual of male Japanese tree frogs as inspiration for their exploration of “swarmalators” – their term for systems in which both synchronization and swarming occur together.

Specifically, they considered oscillators whose phase dynamics and spatial dynamics are coupled. In the instance of the male tree frogs, they attempt to croak in exact anti-phase (one croaks while the other is silent) while moving away from a rival so as to be heard by females.

This opens up “a new class of math problems,” said Strogatz, a Stephen H. Weiss Presidential Fellow. “The question is, what do we expect to see when people start building systems like this or observing them in biology?”

Their paper, “Oscillators That Sync and Swarm,” was published Nov. 13 [2017] in Nature Communications. Strogatz and O’Keeffe – now a postdoctoral researcher with the Senseable City Lab at the Massachusetts Institute of Technology – collaborated with Hyunsuk Hong from Chonbuk National University in Jeonju, South Korea.

Swarming and synchronization both involve large, self-organizing groups of individuals interacting according to simple rules, but rarely have they been studied together, O’Keeffe said.

“No one had connected these two areas, in spite of the fact that there were all these parallels,” he said. “That was the theoretical idea that sort of seduced us, I suppose. And there were also a couple of concrete examples, which we liked – including the tree frogs.”

Studies of swarms focus on how animals move – think of birds flocking or fish schooling – while neglecting the dynamics of their internal states. Studies of synchronization do the opposite: They focus on oscillators’ internal dynamics. Strogatz long has been fascinated by fireflies’ synchrony and other similar phenomena, giving a TED Talk on the topic in 2004, but not on their motion.

“[Swarming and synchronization] are so similar, and yet they were never connected together, and it seems so obvious,” O’Keeffe said. “It’s a whole new landscape of possible behaviors that hadn’t been explored before.”

Using a pair of governing equations that assume swarmalators are free to move about, along with numerical simulations, the group found that a swarmalator system settles into one of five states:

  • Static synchrony – featuring circular symmetry, crystal-like distribution, fully synchronized in phase;
  • Static asynchrony – featuring uniform distribution, meaning that every phase occurs everywhere;
  • Static phase wave – swarmalators settle near others in a phase similar to their own, and phases are frozen at their initial values;
  • Splintered phase wave – nonstationary, disconnected clusters of distinct phases; and
  • Active phase wave – similar to bidirectional states found in biological swarms, where populations split into counter-rotating subgroups; also similar to vortex arrays formed by groups of sperm.

Through the study of simple models, the group found that the coupling of “sync” and “swarm” leads to rich patterns in both time and space, and could lead to further study of systems that exhibit this dual behavior.

“This opens up a lot of questions for many parts of science – there are a lot of things to try that people hadn’t thought of trying,” Strogatz said. “It’s science that opens doors for science. It’s inaugurating science, rather than culminating science.”

One last thing, these frogs have also inspired WiFi improvements (from the Japanese tree frog Wikipedia entry; Note: Links have been removed),

Journalist Toyohiro Akiyama carried some Japanese tree frogs with him during his trip to the Mir space station in December 1990.[citation needed] Calling behavior of the species was used to create an algorithm for optimizing Wi-Fi networks.[3]

While it’s not clear in the Wikipedia entry, the frogs were part of an experiment. Here’s a link to and a citation for the paper about the experiment, along with an abstract,

The Frog in Space (FRIS) experiment onboard Space Station Mir: final report and follow-on studies by Yamashita, M.; Izumi-Kurotani, A.; Mogami, Y.; Okuno,k M.; Naitoh, T.; Wassersug, R. J. Biol Sci Space. 1997 Dec 11(4):313-20.

Abstract

The “Frog in Space” (FRIS) experiment marked a major step for Japanese space life science, on the occasion of the first space flight of a Japanese cosmonaut. At the core of FRIS were six Japanese tree frogs, Hyla japonica, flown on Space Station Mir for 8 days in 1990. The behavior of these frogs was observed and recorded under microgravity. The frogs took up a “parachuting” posture when drifting in a free volume on Mir. When perched on surfaces, they typically sat with their heads bent backward. Such a peculiar posture, after long exposure to microgravity, is discussed in light of motion sickness in amphibians. Histological examinations and other studies were made on the specimens upon recovery. Some organs, such as the liver and the vertebra, showed changes as a result of space flight; others were unaffected. Studies that followed FRIS have been conducted to prepare for a second FRIS on the International Space Station. Interspecific diversity in the behavioral reactions of anurans to changes in acceleration is the major focus of these investigations. The ultimate goal of this research is to better understand how organisms have adapted to gravity through their evolution on earth.
