Are we spending money on the right research? Government of Canada launches Advisory Panel

it’s a little surprising that this is not being managed by the Council of Canadian Academies (CCA) but perhaps their process is not quite nimble enough (from an October 6, 2022 Innovation, Science and Economic Development Canada news release),

Government of Canada launches Advisory Panel on the Federal Research Support System

Members to recommend enhancements to system to position Canadian researchers for success

October 6, 2022 – Ottawa, Ontario

Canada’s success is in large part due to our world-class researchers and their teams who are globally recognized for unleashing bold new ideas, driving technological breakthroughs and addressing complex societal challenges. The Government of Canada recognizes that for Canada to achieve its full potential, support for science and research must evolve as Canadians push beyond what is currently imaginable and continue to find Canadian-made solutions to the world’s toughest problems.

Today [October 6, 2022], the Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry, and the Honourable Jean-Yves Duclos, Minister of Health, launched the Advisory Panel on the Federal Research Support System. Benefiting from the insights of leaders in the science, research and innovation ecosystem, the panel will provide independent, expert policy advice on the structure, governance and management of the federal system supporting research and talent. This will ensure that Canadian researchers are positioned for even more success now and in the future.

The panel will focus on the relationships among the federal research granting agencies—the Natural Sciences and Engineering Research Council of Canada, the Social Sciences and Humanities Research Council of Canada and the Canadian Institutes of Health Research—and the relationship between these agencies and the Canada Foundation for Innovation.

As the COVID-19 pandemic and climate crisis have shown, addressing the world’s most pressing challenges requires greater collaboration within the Canadian research community, government and industry, as well as with the international community. A cohesive and agile research support system will ensure Canadian researchers can quickly and effectively respond to the questions of today and tomorrow. Optimizing Canada’s research support system will equip researchers to transcend disciplines and borders, seize new opportunities and be responsive to emerging needs and interests to improve Canadians’ health, well-being and prosperity.

Quotes

“Canada is known for world-class research thanks to the enormous capabilities of our researchers. Canadian researchers transform curiosity into bold new ideas that can significantly enhance Canadians’ lives and well-being. With this advisory panel, our government will ensure our support for their research is just as cutting-edge as Canada’s science and research community.”
– The Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry

“Our priority is to support Canada’s world-class scientific community so it can respond effectively to the challenges of today and the future. That’s why we are leveraging the expertise and perspectives of a newly formed advisory panel to maximize the impact of research and downstream innovation, which contributes significantly to Canadians’ well-being and prosperity.”
– The Honourable Jean-Yves Duclos, Minister of Health

Quick facts

The Advisory Panel on the Federal Research Support System has seven members, including the Chair. The members were selected by the Minister of Innovation, Science and Industry and the Minister of Health. The panel will consult with experts and stakeholders to draw on their diverse experiences, expertise and opinions. 

Since 2016, the Government of Canada has committed more than $14 billion to support research and science across Canada. 

Here’s a list of advisory panel members I’ve assembled from the Advisory Panel on the Federal Research Support System: Member biographies webpage,

  • Frédéric Bouchard (Chair) is Dean of the Faculty of Arts and Sciences at the Université de Montréal, where he has been a professor of philosophy of science since 2005.
  • Janet Rossant is a Senior Scientist Emeritus in the Developmental and Stem Cell Biology Program, the Hospital for Sick Children and a Professor Emeritus at the University of Toronto’s Department of Molecular Genetics.
  • [Gilles Patry] is Professor Emeritus and President Emeritus at the University of Ottawa. Following a distinguished career as a consulting engineer, researcher and university administrator, Gilles Patry is now a consultant and board director [Royal Canadian Mint].
  • Yolande E. Chan joined McGill University’s Desautels Faculty of Management as Dean and James McGill Professor in 2021. Her research focuses on innovation, knowledge strategy, digital strategy, digital entrepreneurship, and business-IT alignment.
  • Laurel Schafer is a Professor at the Department of Chemistry at the University of British Columbia. Her research focuses on developing novel organometallic catalysts to carry out difficult transformations in small molecule organic chemistry.
  • Vianne Timmons is the President and Vice-Chancellor of Memorial University of Newfoundland since 2020. She is a nationally and internationally recognized researcher and advocate in the field of inclusive education.
  • Dr. Baljit Singh is a highly accomplished researcher, … . He began his role as Vice-President Research at the University of Saskatchewan in 2021, after serving as Dean of the University of Calgary Faculty of Veterinary Medicine (2016 – 2020), and as Associate Dean of Research at the Western College of Veterinary Medicine at the University of Saskatchewan (2010 – 2016).

Nobody from the North. Nobody who’s worked there or lived there or researched there. It’s not the first time I’ve noticed a lack of representation for the North.

Canada’s golden triangle (Montréal, Toronto, Ottawa) is well represented and, as is often the case, there’s representation for other regions: one member from the Prairies, one member from the Maritimes or Atlantic provinces, and one member from the West.

The mandate indicates they could have five to eight members. With seven spots filled, they could include one more member, one from the North.

Even if they don’t add an eighth member, I’m not ready to abandon all hope for involvement from the North when there’s this, from the mandate,

Communications and deliverables

In pursuing its mandate, and to strengthen its advice, the panel may engage with experts and stakeholders to expand access [emphasis mine] to diverse experience, expertise and opinion, and enhance members’ understanding of the topics at hand.

To allow for frank and open discussion, internal panel deliberations among members will be closed.

The panel will deliver a final confidential report by December 2022 [emphasis mine] to the Ministers including recommendations and considerations regarding the modernization of the research support system. A summary of the panel’s observations on the state of the federal research support system may be made public once its deliberations have concluded. The Ministers may also choose to seek confidential advice and/or feedback from the panel on other issues related to the research system.

The panel may also be asked to deliver an interim confidential report to the Ministers by November 2022 [emphases mine], which will provide the panel’s preliminary observations up to that point.

it seems odd there’s no mention of the Pan-Canadian Artificial Intelligence Strategy. It’s my understanding that the funding goes directly from the federal government to the Canadian Institute for Advanced Research (CIFAR), which then distributes the funds. There are other unmentioned science funding agencies, e.g., the National Research Council of Canada and Genome Canada, which (as far as I know) also receive direct funding. It seems that the panel will not be involved in a comprehensive review of Canada’s research support ecosystem.

Plus, I wonder why everything is being kept ‘confidential’. According the government news release, the panel is tasked with finding ways of “optimizing Canada’s research support system.” Do they have security concerns or is this a temporary state of affairs while the government analysts examine the panel’s report?

Chocolate at Canada’s synchrotron (Canadian Light Source; CLS)

An August 31, 2021 Canadian Light Source (CLS) news release by Erin Matthews describes research which could change how chocolate is made,

Scientists used synchrotron technology to show a key ingredient can create the ideal chocolate structure and could revolutionize the chocolate industry.

Structure is key when it comes creating the best quality of chocolate. An ideal internal structure will be smooth and continuous, not crumbly, and result in glossy, delicious, melt-in-your-mouth decadence. However, this sweet bliss is not easy to achieve.

Researchers from the University of Guelph had their first look at the detailed structure of dark chocolate using the Canadian Light Source (CLS) at the University of Saskatchewan. Their results were published today in Nature Communications.

“One of the major problems in chocolate making is tempering,” said Alejandro Marangoni, a professor at the University of Guelph and Canada Research Chair in Food, Health and Aging. “Very much like when you temper steel, you have to achieve a certain crystalline structure in the cocoa butter.”

Skilled chocolate makers [emphasis mine] use specialized tools and training to manipulate cocoa butter for gourmet chocolate. However, Marangoni wondered if adding a special ingredient to chocolate could drive the formation of the correct crystal structure without the complex cooling and mixing procedures typically used by chocolatiers during tempering.

“Imagine if you could add a component that directs the entire crystallization process to a high-quality finished product. You wouldn’t need fancy tempering protocols or industrial machines — you could easily achieve the desired crystalline form just by the addition of this component,” Marangoni said.

His team went to the CLS to see if their secret ingredient, a specific phospholipid, could drive the formation of an ideal chocolate structure. The facility’s bright light, which is millions of times brighter than the sun, allowed the team to get images of the interior structure of their dark chocolate in exquisite detail.

“We have some of the most beautiful micrographs of the finished chocolate that were only possible because we did this work at the CLS,” said Marangoni.

In a world first, the researchers were able to get detailed imaging of the internal structure of dark chocolate, thanks to the synchrotron’s state of the art BMIT beamline.

“Working with the CLS, I would call it a next level interaction,” Marangoni added. “It was extremely easy to set up a project and we had enormous support from beamline scientists.”

In collaboration with CLS Plant Imaging Lead Jarvis Stobbs, Marangoni and colleagues were able to confirm the positive effect their ingredient had on obtaining the ideal structure for chocolate.

“We screened many minor lipid components that would naturally be present in chocolate and identified one preferred group. We then added a very specific molecule, a saturated phospholipid, to the chocolate mass and obtained the desired effect. This phospholipid formed a specific liquid crystal structure that would ‘seed’ the formation of cocoa butter crystals,” said Marangoni.

Their discovery that this phospholipid ingredient will drive the formation of ideal cocoa butter crystals could have a big impact on the way that chocolate is made.

“It could potentially revolutionize the chocolate industry, because we would not need very complex tempering machines,” Marangoni said. “This could open up the possibility for smaller manufacturers to produce chocolate without having the big capital investment for tempering machinery.”

Synchrotron research allows scientists to identify important details that are not possible to find with other techniques. Marangoni said that any small improvement on current manufacturing methods can have a very large impact on the food industry and can potentially save money for companies.

He added that while chocolate research pales in comparison to global problems, he emphasizes the impact food can have on our everyday lives.

“We have more serious problems like climate change and alternative energies and maybe even vegan foods, which we’re working on as well, but chocolate gives us that psychological pleasure. It’s one of these foods that makes us feel happy.”

This video shows the researcher’s delight,

Here’s a link to and a citation for the paper,

Tempering of cocoa butter and chocolate using minor lipidic components by Jay Chen, Saeed M. Ghazani, Jarvis A. Stobbs & Alejandro G. Marangoni. Nature Communications volume 12, Article number: 5018 (2021) DOI: https://doi.org/10.1038/s41467-021-25206-1 Published 31 August 2021

This paper is open access.

According to a Sept. 2, 2021 article by Marc Fawcett-Atkinson for Canada’s National Observer, this work could lead to making chocolate production more sustainable

What happens to the skilled chocolate makers?

That’s one of my big questions. The other is what happens to us? In all these ‘improvements’ of which there are many being touted these days, what I notice is a lack of sensuality. In this particular case, no touch and no smell.

Council of Canadian Academies and its expert panel for the AI for Science and Engineering project

There seems to be an explosion (metaphorically and only by Canadian standards) of interest in public perceptions/engagement/awareness of artificial intelligence (see my March 29, 2021 posting “Canada launches its AI dialogues” and these dialogues run until April 30, 2021 plus there’s this April 6, 2021 posting “UNESCO’s Call for Proposals to highlight blind spots in AI Development open ’til May 2, 2021” which was launched in cooperation with Mila-Québec Artificial Intelligence Institute).

Now there’s this, in a March 31, 2020 Council of Canadian Academies (CCA) news release, four new projects were announced. (Admittedly these are not ‘public engagement’ exercises as such but the reports are publicly available and utilized by policymakers.) These are the two projects of most interest to me,

Public Safety in the Digital Age

Information and communications technologies have profoundly changed almost every aspect of life and business in the last two decades. While the digital revolution has brought about many positive changes, it has also created opportunities for criminal organizations and malicious actors to target individuals, businesses, and systems.

This assessment will examine promising practices that could help to address threats to public safety related to the use of digital technologies while respecting human rights and privacy.

AI for Science and Engineering

The use of artificial intelligence (AI) and machine learning in science and engineering has the potential to radically transform the nature of scientific inquiry and discovery and produce a wide range of social and economic benefits for Canadians. But, the adoption of these technologies also presents a number of potential challenges and risks.

This assessment will examine the legal/regulatory, ethical, policy and social challenges related to the use of AI technologies in scientific research and discovery.

Sponsor: National Research Council Canada [NRC] (co-sponsors: CIFAR [Canadian Institute for Advanced Research], CIHR [Canadian Institutes of Health Research], NSERC [Natural Sciences and Engineering Research Council], and SSHRC [Social Sciences and Humanities Research Council])

For today’s posting the focus will be on the AI project, specifically, the April 19, 2021 CCA news release announcing the project’s expert panel,

The Council of Canadian Academies (CCA) has formed an Expert Panel to examine a broad range of factors related to the use of artificial intelligence (AI) technologies in scientific research and discovery in Canada. Teresa Scassa, SJD, Canada Research Chair in Information Law and Policy at the University of Ottawa, will serve as Chair of the Panel.  

“AI and machine learning may drastically change the fields of science and engineering by accelerating research and discovery,” said Dr. Scassa. “But these technologies also present challenges and risks. A better understanding of the implications of the use of AI in scientific research will help to inform decision-making in this area and I look forward to undertaking this assessment with my colleagues.”

As Chair, Dr. Scassa will lead a multidisciplinary group with extensive expertise in law, policy, ethics, philosophy, sociology, and AI technology. The Panel will answer the following question:

What are the legal/regulatory, ethical, policy and social challenges associated with deploying AI technologies to enable scientific/engineering research design and discovery in Canada?

“We’re delighted that Dr. Scassa, with her extensive experience in AI, the law and data governance, has taken on the role of Chair,” said Eric M. Meslin, PhD, FRSC, FCAHS, President and CEO of the CCA. “I anticipate the work of this outstanding panel will inform policy decisions about the development, regulation and adoption of AI technologies in scientific research, to the benefit of Canada.”

The CCA was asked by the National Research Council of Canada (NRC), along with co-sponsors CIFAR, CIHR, NSERC, and SSHRC, to address the question. More information can be found here.

The Expert Panel on AI for Science and Engineering:

Teresa Scassa (Chair), SJD, Canada Research Chair in Information Law and Policy, University of Ottawa, Faculty of Law (Ottawa, ON)

Julien Billot, CEO, Scale AI (Montreal, QC)

Wendy Hui Kyong Chun, Canada 150 Research Chair in New Media and Professor of Communication, Simon Fraser University (Burnaby, BC)

Marc Antoine Dilhac, Professor (Philosophy), University of Montreal; Director of Ethics and Politics, Centre for Ethics (Montréal, QC)

B. Courtney Doagoo, AI and Society Fellow, Centre for Law, Technology and Society, University of Ottawa; Senior Manager, Risk Consulting Practice, KPMG Canada (Ottawa, ON)

Abhishek Gupta, Founder and Principal Researcher, Montreal AI Ethics Institute (Montréal, QC)

Richard Isnor, Associate Vice President, Research and Graduate Studies, St. Francis Xavier University (Antigonish, NS)

Ross D. King, Professor, Chalmers University of Technology (Göteborg, Sweden)

Sabina Leonelli, Professor of Philosophy and History of Science, University of Exeter (Exeter, United Kingdom)

Raymond J. Spiteri, Professor, Department of Computer Science, University of Saskatchewan (Saskatoon, SK)

Who is the expert panel?

Putting together a Canadian panel is an interesting problem especially so when you’re trying to find people of expertise who can also represent various viewpoints both professionally and regionally. Then, there are gender, racial, linguistic, urban/rural, and ethnic considerations.

Statistics

Eight of the panelists could be said to be representing various regions of Canada. Five of those eight panelists are based in central Canada, specifically, Ontario (Ottawa) or Québec (Montréal). The sixth panelist is based in Atlantic Canada (Nova Scotia), the seventh panelist is based in the Prairies (Saskatchewan), and the eighth panelist is based in western Canada, (Vancouver, British Columbia).

The two panelists bringing an international perspective to this project are both based in Europe, specifically, Sweden and the UK.

(sigh) It would be good to have representation from another part of the world. Asia springs to mind as researchers in that region are very advanced in their AI research and applications meaning that their experts and ethicists are likely to have valuable insights.

Four of the ten panelists are women, which is closer to equal representation than some of the other CCA panels I’ve looked at.

As for Indigenous and BIPOC representation, unless one or more of the panelists chooses to self-identify in that fashion, I cannot make any comments. It should be noted that more than one expert panelist focuses on social justice and/or bias in algorithms.

Network of relationships

As you can see, the CCA descriptions for the individual members of the expert panel are a little brief. So, I did a little digging and In my searches, I noticed what seems to be a pattern of relationships among some of these experts. In particular, take note of the Canadian Institute for Advanced Research (CIFAR) and the AI Advisory Council of the Government of Canada.

Individual panelists

Teresa Scassa (Ontario) whose SJD designation signifies a research doctorate in law chairs this panel. Offhand, I can recall only one or two other panels being chaired by women of the 10 or so I’ve reviewed. In addition to her profile page at the University of Ottawa, she hosts her own blog featuring posts such as “How Might Bill C-11 Affect the Outcome of a Clearview AI-type Complaint?” She writes clearly (I didn’t seen any jargon) for an audience that is somewhat informed on the topic.

Along with Dilhac, Teresa Scassa is a member of the AI Advisory Council of the Government of Canada. More about that group when you read Dilhac’s description.

Julien Billot (Québec) has provided a profile on LinkedIn and you can augment your view of M. Billot with this profile from the CreativeDestructionLab (CDL),

Mr. Billot is a member of the faculty at HEC Montréal [graduate business school of the Université de Montréal] as an adjunct professor of management and the lead for the CreativeDestructionLab (CDL) and NextAi program in Montreal.

Julien Billot has been President and Chief Executive Officer of Yellow Pages Group Corporation (Y.TO) in Montreal, Quebec. Previously, he was Executive Vice President, Head of Media and Member of the Executive Committee of Solocal Group (formerly PagesJaunes Groupe), the publicly traded and incumbent local search business in France. Earlier experience includes serving as CEO of the digital and new business group of Lagardère Active, a multimedia branch of Lagardère Group and 13 years in senior management positions at France Telecom, notably as Chief Marketing Officer for Orange, the company’s mobile subsidiary.

Mr. Billot is a graduate of École Polytechnique (Paris) and from Telecom Paris Tech. He holds a postgraduate diploma (DEA) in Industrial Economics from the University of Paris-Dauphine.

Wendy Hui Kyong Chun (British Columbia) has a profile on the Simon Fraser University (SFU) website, which provided one of the more interesting (to me personally) biographies,

Wendy Hui Kyong Chun is the Canada 150 Research Chair in New Media at Simon Fraser University, and leads the Digital Democracies Institute which was launched in 2019. The Institute aims to integrate research in the humanities and data sciences to address questions of equality and social justice in order to combat the proliferation of online “echo chambers,” abusive language, discriminatory algorithms and mis/disinformation by fostering critical and creative user practices and alternative paradigms for connection. It has four distinct research streams all led by Dr. Chun: Beyond Verification which looks at authenticity and the spread of disinformation; From Hate to Agonism, focusing on fostering democratic exchange online; Desegregating Network Neighbourhoods, combatting homophily across platforms; and Discriminating Data: Neighbourhoods, Individuals and Proxies, investigating the centrality of race, gender, class and sexuality [emphasis mine] to big data and network analytics.

I’m glad to see someone who has focused on ” … the centrality of race, gender, class and sexuality to big data and network analytics.” Even more interesting to me was this from her CV (curriculum vitae),

Professor, Department of Modern Culture and Media, Brown University, July 2010-June 2018

.•Affiliated Faculty, Multimedia & Electronic Music Experiments (MEME), Department of Music,2017.

•Affiliated Faculty, History of Art and Architecture, March 2012-

.•Graduate Field Faculty, Theatre Arts and Performance Studies, Sept 2008-.[sic]

….

[all emphases mine]

And these are some of her credentials,

Ph.D., English, Princeton University, 1999.
•Certificate, School of Criticism and Theory, Dartmouth College, Summer 1995.

M.A., English, Princeton University, 1994.

B.A.Sc., Systems Design Engineering and English, University of Waterloo, Canada, 1992.
•first class honours and a Senate Commendation for Excellence for being the first student to graduate from the School of Engineering with a double major

It’s about time the CCA started integrating some of kind of arts perspective into their projects. (Although, I can’t help wondering if this was by accident rather than by design.)

Marc Antoine Dilhac, an associate professor at l’Université de Montréal, he, like Billot, graduated from a French university, in his case, the Sorbonne. Here’s more from Dilhac’s profile on the Mila website,

Marc-Antoine Dilhac (Ph.D., Paris 1 Panthéon-Sorbonne) is a professor of ethics and political philosophy at the Université de Montréal and an associate member of Mila – Quebec Artificial Intelligence Institute. He currently holds a CIFAR [Canadian Institute for Advanced Research] Chair in AI ethics (2019-2024), and was previously Canada Research Chair in Public Ethics and Political Theory 2014-2019. He specialized in theories of democracy and social justice, as well as in questions of applied ethics. He published two books on the politics of toleration and inclusion (2013, 2014). His current research focuses on the ethical and social impacts of AI and issues of governance and institutional design, with a particular emphasis on how new technologies are changing public relations and political structures.

In 2017, he instigated the project of the Montreal Declaration for a Responsible Development of AI and chaired its scientific committee. In 2020, as director of Algora Lab, he led an international deliberation process as part of UNESCO’s consultation on its recommendation on the ethics of AI.

In 2019, he founded Algora Lab, an interdisciplinary laboratory advancing research on the ethics of AI and developing a deliberative approach to the governance of AI and digital technologies. He is co-director of Deliberation at the Observatory on the social impacts of AI and digital technologies (OBVIA), and contributes to the OECD Policy Observatory (OECD.AI) as a member of its expert network ONE.AI.

He sits on the AI Advisory Council of the Government of Canada and co-chair its Working Group on Public Awareness.

Formerly known as Mila only, Mila – Quebec Artificial Intelligence Institute is a beneficiary of the 2017 Canadian federal budget’s inception of the Pan-Canadian Artificial Intelligence Strategy, which named CIFAR as an agency that would benefit as the hub and would also distribute funds for artificial intelligence research to (mainly) three agencies: Mila in Montréal, the Vector Institute in Toronto, and the Alberta Machine Intelligence Institute (AMII; Edmonton).

Consequently, Dilhac’s involvement with CIFAR is not unexpected but when added to his presence on the AI Advisory Council of the Government of Canada and his role as co-chair of its Working Group on Public Awareness, one of the co-sponsors for this future CCA report, you get a sense of just how small the Canadian AI ethics and public awareness community is.

Add in CIFAR’s Open Dialogue: AI in Canada series (ongoing until April 30, 2021) which is being held in partnership with the AI Advisory Council of the Government of Canada (see my March 29, 2021 posting for more details about the dialogues) amongst other familiar parties and you see a web of relations so tightly interwoven that if you could produce masks from it you’d have superior COVID-19 protection to N95 masks.

These kinds of connections are understandable and I have more to say about them in my final comments.

B. Courtney Doagoo has a profile page at the University of Ottawa, which fills in a few information gaps,

As a Fellow, Dr. Doagoo develops her research on the social, economic and cultural implications of AI with a particular focus on the role of laws, norms and policies [emphasis mine]. She also notably advises Dr. Florian Martin-Bariteau, CLTS Director, in the development of a new research initiative on those topical issues, and Dr. Jason Millar in the development of the Canadian Robotics and Artificial Intelligence Ethical Design Lab (CRAiEDL).

Dr. Doagoo completed her Ph.D. in Law at the University of Ottawa in 2017. In her interdisciplinary research, she used empirical methods to learn about and describe the use of intellectual property law and norms in creative communities. Following her doctoral research, she joined the World Intellectual Property Organization’s Coordination Office in New York as a legal intern and contributed to developing the joint initiative on gender and innovation in collaboration with UNESCO and UN Women. She later joined the International Law Research Program at the Centre for International Governance Innovation as a Post-Doctoral Fellow, where she conducted research in technology and law focusing on intellectual property law, artificial intelligence and data governance.

Dr. Doagoo completed her LL.L. at the University of Ottawa, and LL.M. in Intellectual Property Law at the Benjamin N. Cardozo School of Law [a law school at Yeshiva University in New York City].  In between her academic pursuits, Dr. Doagoo has been involved with different technology start-ups, including the one she is currently leading aimed at facilitating access to legal services. She’s also an avid lover of the arts and designed a course on Arts and Cultural Heritage Law taught during her doctoral studies at the University of Ottawa, Faculty of Law.

It’s probably because I don’t know enough but this “the role of laws, norms and policies” seems bland to the point of meaningless. The rest is more informative and brings it back to the arts with Wendy Hui Kyong Chun at SFU.

Doagoo’s LinkedIn profile offers an unexpected link to this expert panel’s chairperson, Teresa Scassa (in addition to both being lawyers whose specialties are in related fields and on faculty or fellow at the University of Ottawa),

Soft-funded Research Bursary

Dr. Teresa Scassa

2014

I’m not suggesting any conspiracies; it’s simply that this is a very small community with much of it located in central and eastern Canada and possible links into the US. For example, Wendy Hui Kyong Chun, prior to her SFU appointment in December 2018, worked and studied in the eastern US for over 25 years after starting her academic career at the University of Waterloo (Ontario).

Abhishek Gupta provided me with a challenging search. His LinkedIn profile yielded some details (I’m not convinced the man sleeps), Note: I have made some formatting changes and removed the location, ‘Montréal area’ from some descriptions

Exhausting, eh? He also has an eponymous website and the Montreal AI Ethics Institute can found here where Gupta and his colleagues are “Democratizing AI ethics literacy.” My hat’s off to Gupta getting on an expert panel for CCA is quite an achievement for someone without the usual academic and/or industry trappings.

Richard Isnor, based in Nova Scotia and associate vice president of research & graduate studies at St. Francis Xavier University (StFX), seems to have some connection to northern Canada (see the reference to Nunavut Research Institute below); he’s certainly well connected to various federal government agencies according to his profile page,

Prior to joining StFX, he was Manager of the Atlantic Regional Office for the Natural Sciences and Engineering Research Council of Canada (NSERC), based in Moncton, NB.  Previously, he was Director of Innovation Policy and Science at the International Development Research Centre in Ottawa and also worked for three years with the National Research Council of Canada [NRC] managing Biotechnology Research Initiatives and the NRC Genomics and Health Initiative.

Richard holds a D. Phil. in Science and Technology Policy Studies from the University of Sussex, UK; a Master’s in Environmental Studies from Dalhousie University [Nova Scotia]; and a B. Sc. (Hons) in Biochemistry from Mount Allison University [New Burnswick].  His primary interest is in science policy and the public administration of research; he has worked in science and technology policy or research administrative positions for Environment Canada, Natural Resources Canada, the Privy Council Office, as well as the Nunavut Research Institute. [emphasis mine]

I don’t know what Dr. Isnor’s work is like but I’m hopeful he (along with Spiteri) will be able to provide a less ‘big city’ perspective to the proceedings.

(For those unfamiliar with Canadian cities, Montreal [three expert panelists] is the second largest city in the country, Ottawa [two expert panelists] as the capital has an outsize view of itself, Vancouver [one expert panelist] is the third or fourth largest city in the country for a total of six big city representatives out of eight Canadian expert panelists.)

Ross D. King, professor of machine intelligence at Sweden’s Chalmers University of Technology, might be best known for Adam, also known as, Robot Scientist. Here’s more about King, from his Wikipedia entry (Note: Links have been removed),

King completed a Bachelor of Science degree in Microbiology at the University of Aberdeen in 1983 and went on to study for a Master of Science degree in Computer Science at the University of Newcastle in 1985. Following this, he completed a PhD at The Turing Institute [emphasis mine] at the University of Strathclyde in 1989[3] for work on developing machine learning methods for protein structure prediction.[7]

King’s research interests are in the automation of science, drug design, AI, machine learning and synthetic biology.[8][9] He is probably best known for the Robot Scientist[4][10][11][12][13][14][15][16][17] project which has created a robot that can:

hypothesize to explain observations

devise experiments to test these hypotheses

physically run the experiments using laboratory robotics

interpret the results from the experiments

repeat the cycle as required

The Robot Scientist Wikipedia entry has this to add,

… a laboratory robot created and developed by a group of scientists including Ross King, Kenneth Whelan, Ffion Jones, Philip Reiser, Christopher Bryant, Stephen Muggleton, Douglas Kell and Steve Oliver.[2][6][7][8][9][10]

… Adam became the first machine in history to have discovered new scientific knowledge independently of its human creators.[5][17][18]

Sabina Leonelli, professor of philosophy and history of science at the University of Exeter, is the only person for whom I found a Twitter feed (@SabinaLeonelli). Here’s a bit more from her Wikipedia entry Note: Links have been removed),

Originally from Italy, Leonelli moved to the UK for a BSc degree in History, Philosophy and Social Studies of Science at University College London and a MSc degree in History and Philosophy of Science at the London School of Economics. Her doctoral research was carried out in the Netherlands at the Vrije Universiteit Amsterdam with Henk W. de Regt and Hans Radder. Before joining the Exeter faculty, she was a research officer under Mary S. Morgan at the Department of Economic History of the London School of Economics.

Leonelli is the Co-Director of the Exeter Centre for the Study of the Life Sciences (Egenis)[3] and a Turing Fellow at the Alan Turing Institute [emphases mine] in London.[4] She is also Editor-in-Chief of the international journal History and Philosophy of the Life Sciences[5] and Associate Editor for the Harvard Data Science Review.[6] She serves as External Faculty for the Konrad Lorenz Institute for Evolution and Cognition Research.[7]

Notice that Ross King and Sabina Leonelli both have links to The Alan Turing Institute (“We believe data science and artificial intelligence will change the world”), although the institute’s link to the University of Strathclyde (Scotland) where King studied seems a bit tenuous.

Do check out Leonelli’s profile at the University of Exeter as it’s comprehensive.

Raymond J. Spiteri, professor and director of the Centre for High Performance Computing, Department of Computer Science at the University of Saskatchewan, has a profile page at the university the likes of which I haven’t seen in several years perhaps due to its 2013 origins. His other university profile page can best be described as minimalist.

His Canadian Applied and Industrial Mathematics Society (CAIMS) biography page could be described as less charming (to me) than the 2013 profile but it is easier to read,

Raymond Spiteri is a Professor in the Department of Computer Science at the University of Saskatchewan. He performed his graduate work as a member of the Institute for Applied Mathematics at the University of British Columbia. He was a post-doctoral fellow at McGill University and held faculty positions at Acadia University and Dalhousie University before joining USask in 2004. He serves on the Executive Committee of the WestGrid High-Performance Computing Consortium with Compute/Calcul Canada. He was a MITACS Project Leader from 2004-2012 and served in the role of Mitacs Regional Scientific Director for the Prairie Provinces between 2008 and 2011.

Spiteri’s areas of research are numerical analysis, scientific computing, and high-performance computing. His area of specialization is the analysis and implementation of efficient time-stepping methods for differential equations. He actively collaborates with scientists, engineers, and medical experts of all flavours. He also has a long record of industry collaboration with companies such as IBM and Boeing.

Spiteri has been lifetime member of CAIMS/SCMAI since 2000. He helped co-organize the 2004 Annual Meeting at Dalhousie and served on the Cecil Graham Doctoral Dissertation Award Committee from 2005 to 2009, acting as chair from 2007. He has been an active participant in CAIMS, serving several times on the Scientific Committee for the Annual Meeting, as well as frequently attending and organizing mini-symposia. Spiteri believes it is important for applied mathematics to play a major role in the efforts to meet Canada’s most pressing societal challenges, including the sustainability of our healthcare system, our natural resources, and the environment.

A last look at Spiteri’s 2013 profile gave me this (Note: Links have been removed),

Another biographical note: I obtained my B.Sc. degree in Applied Mathematics from the University of Western Ontario [also known as, Western University] in 1990. My advisor was Dr. M.A.H. (Paddy) Nerenberg, after whom the Nerenberg Lecture Series is named. Here is an excerpt from the description, put here is his honour, as a model for the rest of us:

The Nerenberg Lecture Series is first and foremost about people and ideas. Knowledge is the true treasure of humanity, accrued and passed down through the generations. Some of it, particularly science and its language, mathematics, is closed in practice to many because of technical barriers that can only be overcome at a high price. These technical barriers form part of the remarkable fractures that have formed in our legacy of knowledge. We are so used to those fractures that they have become almost invisible to us, but they are a source of profound confusion about what is known.

The Nerenberg Lecture is named after the late Morton (Paddy) Nerenberg, a much-loved professor and researcher born on 17 March– hence his nickname. He was a Professor at Western for more than a quarter century, and a founding member of the Department of Applied Mathematics there. A successful researcher and accomplished teacher, he believed in the unity of knowledge, that scientific and mathematical ideas belong to everyone, and that they are of human importance. He regretted that they had become inaccessible to so many, and anticipated serious consequences from it. [emphases mine] The series honors his appreciation for the democracy of ideas. He died in 1993 at the age of 57.

So, we have the expert panel.

Thoughts about the panel and the report

As I’ve noted previously here and elsewhere, assembling any panels whether they’re for a single event or for a longer term project such as producing a report is no easy task. Looking at the panel, there’s some arts representation, smaller urban centres are also represented, and some of the members have experience in more than one region in Canada. I was also much encouraged by Spiteri’s acknowledgement of his advisor’s, Morton (Paddy) Nerenberg, passionate commitment to the idea that “scientific and mathematical ideas belong to everyone.”

Kudos to the Council of Canadian Academies (CCA) organizers.

That said, this looks like an exceptionally Eurocentric panel. Unusually, there’s no representation from the US unless you count Chun who has spent the majority of her career in the US with only a little over two years at Simon Fraser University on Canada’s West Coast.

There’s weakness to a strategy (none of the ten or so CCA reports I’ve reviewed here deviates from this pattern) that seems to favour international participants from Europe and/or the US (also, sometimes, Australia/New Zealand). This leaves out giant chunks of the international community and brings us dangerously close to an echo chamber.

The same problem exists regionally and with various Canadian communities, which are acknowledged more in spirit than in actuality, e.g., the North, rural, indigenous, arts, etc.

Getting back to the ‘big city’ emphsais noted earlier, two people from Ottawa and three from Montreal; half of the expert panel lives within a two hour train ride of each other. (For those who don’t know, that’s close by Canadian standards. For comparison, a train ride from Vancouver to Seattle [US] is about four hours, a short trip when compared to a 24 hour train trip to the closest large Canadian cities.)

I appreciate that it’s not a simple problem but my concern is that it’s never acknowledged by the CCA. Perhaps they could include a section in the report acknowledging the issues and how the expert panel attempted to address them , in other words, transparency. Coincidentally, transparency, which has been related to trust, have both been identified as big issues with artificial intelligence.

As for solutions, these reports get sent to external reviewers and, prior to the report, outside experts are sometimes brought in as the panel readies itself. That would be two opportunities afforded by their current processes.

Anyway, good luck with the report and I look forward to seeing it.

Longer lasting N95 masks thanks to a synchrotron in Saskatchewan (Canada)

A Nov. 3, 2020 Canadian Light Sources (CLS; also known as a synchrotron) news release by Erin Matthews (also on the University of Saskatchewan website), received via email, announces a technique that may make N95 masks last longer,

Through a collaboration between the Canadian Light Source (CLS) and the Vaccine and Infectious Disease Organization-International Vaccine Centre (VIDO-InterVac)—both national research facilities at the University of Saskatchewan (USask) —scientists hope to understand the structural changes happening inside N95 respirator masks after being sterilized for reuse.  

Cutting-edge techniques unique to the CLS enable the team to analyze minute details in the masks that would be impossible to see with other methods. CLS Industrial Scientist Toby Bond is using X-rays produced by the synchrotron to see the tightly woven, microscopic fibres that are crucial to the filtering power of N95 respirators.  

N95 respirators get their name from their ability to filter at least 95 per cent of particles circulating in the air. These particular masks are used by frontline health-care workers for protection against COVID-19.  

However, N95 masks that were intended for one-time use were in short supply globally during the height of the pandemic this spring, and continue to be chronically unavailable in most parts of the world. As a result, health-care agencies and researchers have been looking for ways to sterilize masks for reuse to help ensure an emergency supply. 

While previous research has found that certain methods work better at maintaining the integrity of the masks following decontamination, Bond and colleagues want to understand why this happens and how to extend the lifespan of these critical masks. 

“We want to use the unique tools we have at the CLS to look at the fibres that actually do the filtering,” Bond said. “We use a specialized X-ray microscope to take tiny CT scans before and after exposing the N95 masks to different decontamination protocols. Previous research has shown that certain methods work better than others, but we don’t currently know what’s going on inside the mask at a microscopic level.”  

Bond is working to determine why the N95 mask fibres degrade. This information would enable manufacturers to design more resilient masks and help the medical industry move towards personal protective equipment that is designed to be reusable. 

“One thing that’s unique about a synchrotron CT scan is that we can scan a tiny fraction of the mask at high magnification without having to cut small pieces out of it. This is what allows us to do before-and-after imaging, since we can decontaminate the mask in its real-world environment without altering it,” Bond added. 

One method for decontaminating N95 masks, called vaporized hydrogen peroxide (VHP), is used to sterilize rooms and equipment in VIDO-InterVac.  

“With the outbreak of the pandemic and the recognized potential worldwide shortage of respirators, we were approached by the Saskatchewan Health Authority (SHA) to investigate the possibility of using VHP decontamination on N95 respirators to mitigate a potential shortage,” said VIDO-InterVac Biosafety Officer Tracey Thue.  

To date, VIDO-InterVac has sterilized more than 13,000 masks. Studies have demonstrated that N95 masks can undergo multiple VHP decontamination cycles without affecting mask integrity. 

When CLS Laboratory Co-ordinator Burke Barlow suggested that the two groups collaborate, Thue offered to run three styles of N95 respirators through their VHP system for Bond’s research. Bond compared the VHP-treated masks to others that he had treated with Moist Heat Incubation (MHI) and autoclaving. 

Autoclaving is a common decontamination method that uses hot pressurized steam to sterilize medical devices, however it is the most damaging method and certain masks do not survive even one autoclave sterilization cycle. MHI is gentler than the autoclave, but the masks still become less effective after repeated cycles. VHP is considered to be the best method for decontamination of N95s, but it requires specialized equipment that is not widely available in hospitals. 

Bond and his colleagues are using the BMIT beamline at the CLS, a one-of-a-kind tool in North America, to image the inside of the masks in three dimensions without damaging them. The researchers can then look at the structure of individual fibres in the masks to see how they change during decontamination. They can identify shifts in mask fibres as small as a few microns, which is a measurement much smaller than the width of a human hair.  

Analyses over the next few weeks will help clarify what effect these shifts have on the performance of the mask. Aerodynamic and fluid simulations conducted at the CLS will help show how the changes in mask fibre structure affect air flow.   

“Preliminary results show there is a gradual unravelling of the fibres during repeated exposure to MHI in some masks,” said Bond. “This is in contrast to autoclaving the masks, which immediately causes a very significant unravelling after a single decontamination.” 

“In some cases, this unravelling doesn’t affect the filtration, but it does affect the overall structure of the mask, causing it to fit poorly and no longer seal properly to the user’s face,” he added. “This indicates that manufacturers could potentially make an autoclavable mask by changing the structural parts of the mask and leaving the filtration layer as it is.” 

“In terms of Toby’s research at the CLS, being able to go down to the microscopic level and visualize changes in the material or lack there-of is another valuable piece of information,” Thue said. 

Bond emphasized that it’s not just tools and equipment that makes this kind of research possible at the CLS, but also the access to the vast research network at USask.  

“The CLS is a fantastic place to do research like this, since we’re a national facility with a broad network of researchers,” said Bond. “We’ve been able to work with our colleagues at VIDO-InterVac (which is just down the road on the USask campus), and we also have contacts in industry and academia who work in this sector that have helped us with the experiments.” 

Oddly, there is no reference to a published paper for this work or mention of future research into how manufacturers might make use of this information.

Blue quantum dots and your television screen

Scientists used equipment at the Canadian Light Source (CLS; synchrotron in Saskatoon, Saskatchewan, Canada) in the quest for better glowing dots on your television (maybe computers and telephones, too?) screen. From an August 20, 2020 news item on Nanowerk,

There are many things quantum dots could do, but the most obvious place they could change our lives is to make the colours on our TVs and screens more pristine. Research using the Canadian Light Source (CLS) at the University of Saskatchewan is helping to bring this technology closer to our living rooms.

An August 19, 2020 CLS news release (also received via email) by Victoria Martinez, which originated the news item, explains what quantum dots are and fills in with technical details about this research,

Quantum dots are nanocrystals that glow, a property that scientists have been working with to develop next-generation LEDs. When a quantum dot glows, it creates very pure light in a precise wavelength of red, blue or green. Conventional LEDs, found in our TV screens today, produce white light that is filtered to achieve desired colours, a process that leads to less bright and muddier colours.

Until now, blue-glowing quantum dots, which are crucial for creating a full range of colour, have proved particularly challenging for researchers to develop. However, University of Toronto (U of T) researcher Dr. Yitong Dong and collaborators have made a huge leap in blue quantum dot fluorescence, results they recently published in Nature Nanotechnology.

“The idea is that if you have a blue LED, you have everything. We can always down convert the light from blue to green and red,” says Dong. “Let’s say you have green, then you cannot use this lower-energy light to make blue.”

The team’s breakthrough has led to quantum dots that produce green light at an external quantum efficiency (EQE) of 22% and blue at 12.3%. The theoretical maximum efficiency is not far off at 25%, and this is the first blue perovskite LED reported as achieving an EQE higher than 10%.

The Science

Dong has been working in the field of quantum dots for two years in Dr. Edward Sargent’s research group at the U of T. This astonishing increase in efficiency took time, an unusual production approach, and overcoming several scientific hurdles to achieve.

CLS techniques, particularly GIWAXS [grazing incidence wide-angle X-ray scattering] on the HXMA beamline [hard X-ray micro-analysis (HXMA)], allowed the researchers to verify the structures achieved in their quantum dot films. This validated their results and helped clarify what the structural changes achieve in terms of LED performance.

“The CLS was very helpful. GIWAXS is a fascinating technique,” says Dong.

The first challenge was uniformity, important to ensuring a clear blue colour and to prevent the LED from moving towards producing green light.

“We used a special synthetic approach to achieve a very uniform assembly, so every single particle has the same size and shape. The overall film is nearly perfect and maintains the blue emission conditions all the way through,” says Dong.

Next, the team needed to tackle the charge injection needed to excite the dots into luminescence. Since the crystals are not very stable, they need stabilizing molecules to act as scaffolding and support them. These are typically long molecule chains, with up to 18 carbon-non-conductive molecules at the surface, making it hard to get the energy to produce light.

“We used a special surface structure to stabilize the quantum dot. Compared to the films made with long chain molecules capped quantum dots, our film has 100 times higher conductivity, sometimes even 1000 times higher.”

This remarkable performance is a key benchmark in bringing these nanocrystal LEDs to market. However, stability remains an issue and quantum dot LEDs suffer from short lifetimes. Dong is excited about the potential for the field and adds, “I like photons, these are interesting materials, and, well, these glowing crystals are just beautiful.”

News from the Canadian Light Source (CLS), Canadian Science Policy Conference (CSPC) 2020, the International Symposium on Electronic Arts (ISEA) 2020, and HotPopRobot

I have some news about conserving art; early bird registration deadlines for two events, and, finally, an announcement about contest winners.

Canadian Light Source (CLS) and modern art

Rita Letendre. Victoire [Victory], 1961. Oil on canvas, Overall: 202.6 × 268 cm. Art Gallery of Ontario. Gift of Jessie and Percy Waxer, 1974, donated by the Ontario Heritage Foundation, 1988. © Rita Letendre L74.8. Photography by Ian Lefebvre

This is one of three pieces by Rita Letendre that underwent chemical mapping according to an August 5, 2020 CLS news release by Victoria Martinez (also received via email),

Research undertaken at the Canadian Light Source (CLS) at the University of Saskatchewan was key to understanding how to conserve experimental oil paintings by Rita Letendre, one of Canada’s most respected living abstract artists.

The work done at the CLS was part of a collaborative research project between the Art Gallery of Ontario (AGO) and the Canadian Conservation Institute (CCI) that came out of a recent retrospective Rita Letendre: Fire & Light at the AGO. During close examination, Meaghan Monaghan, paintings conservator from the Michael and Sonja Koerner Centre for Conservation, observed that several of Letendre’s oil paintings from the fifties and sixties had suffered significant degradation, most prominently, uneven gloss and patchiness, snowy crystalline structures coating the surface known as efflorescence, and cracking and lifting of the paint in several areas.

Kate Helwig, Senior Conservation Scientist at the Canadian Conservation Institute, says these problems are typical of mid-20th century oil paintings. “We focused on three of Rita Letendre’s paintings in the AGO collection, which made for a really nice case study of her work and also fits into the larger question of why oil paintings from that period tend to have degradation issues.”

Growing evidence indicates that paintings from this period have experienced these problems due to the combination of the experimental techniques many artists employed and the additives paint manufacturers had begun to use.

In order to determine more precisely how these factors affected Letendre’s paintings, the research team members applied a variety of analytical techniques, using microscopic samples taken from key points in the works.

“The work done at the CLS was particularly important because it allowed us to map the distribution of materials throughout a paint layer such as an impasto stroke,” Helwig said. The team used Mid-IR chemical mapping at the facility, which provides a map of different molecules in a small sample.

For example, chemical mapping at the CLS allowed the team to understand the distribution of the paint additive aluminum stearate throughout the paint layers of the painting Méduse. This painting showed areas of soft, incompletely dried paint, likely due to the high concentration and incomplete mixing of this additive. 

The painting Victoire had a crumbling base paint layer in some areas and cracking and efflorescence at the surface in others.  Infrared mapping at the CLS allowed the team to determine that excess free fatty acids in the paint were linked to both problems; where the fatty acids were found at the base they formed zing “soaps” which led to crumbling and cracking, and where they had moved to the surface they had crystallized, causing the snowflake-like efflorescence.

AGO curators and conservators interviewed Letendre to determine what was important to her in preserving and conserving her works, and she highlighted how important an even gloss across the surface was to her artworks, and the philosophical importance of the colour black in her paintings. These priorities guided conservation efforts, while the insights gained through scientific research will help maintain the works in the long term.

In order to restore the black paint to its intended even finish for display, conservator Meaghan Monaghan removed the white crystallization from the surface of Victoire, but it is possible that it could begin to recur. Understanding the processes that lead to this degradation will be an important tool to keep Letendre’s works in good condition.

“The world of modern paint research is complicated; each painting is unique, which is why it’s important to combine theoretical work on model paint systems with this kind of case study on actual works of art” said Helwig. The team hopes to collaborate on studying a larger cross section of Letendre’s paintings in oil and acrylic in the future to add to the body of knowledge.

There are many presentations focused on COVID-19 and.or health.

There doesn’t seem to be much focus on cyber security and, given that we just lost two ice caps (see Brandon Spektor’s August 1, 2020 article [Two Canadian ice caps have completely vanished from the Arctic, NASA imagery shows] on the Live Science website), it’s surprising that there are no presentations concerning the Arctic.

International Symposium on Electronic Arts (ISEA) 2020

According to my latest information, the early bird rate for ISEA 2020 (Oct. 13 -18) ends on August 13, 2020. (My June 22, 2020 posting describes their plans for the online event.)

You can find registration information here.

Margaux Davoine has written up a teaser for the 2020 edition of ISEA in the form of an August 6, 2020 interview with Yan Breuleux. I’ve excerpted one bit,

Finally, thinking about this year’s theme [Why Sentience?], there might be something a bit ironic about exploring the notion of sentience (historically reserved for biological life, and quite a small subsection of it) through digital media and electronic arts. There’s been much work done in the past 25 years to loosen the boundaries between such distinctions: how do you imagine ISEA2020 helping in that?

The similarities shared between humans, animals, and machines are fundamental in cybernetic sciences. According to the founder of cybernetics Norbert Wiener, the main tenets of the information paradigm – the notion of feedback – can be applied to humans, animals as well as the material world. Famously, the AA predictor (as analysed by Peter Galison in 1994) can be read as a first attempt at human-machine fusion (otherwise known as a cyborg).

The infamous Turing test also tends to blur the lines between humans and machines, between language and informational systems. Second-order cybernetics are often associated with biologists Francisco Varela and Humberto Maturana. The very notion of autopoiesis (a system capable of maintaining a certain level of stability in an unstable environment) relates back to the concept of homeostasis formulated by Willam Ross [William Ross Ashby] in 1952. Moreover, the concept of “ecosystems” emanates directly from the field of second-order cybernetics, providing researchers with a clearer picture of the interdependencies between living and non-living organisms. In light of these theories, the absence of boundaries between animals, humans, and machines constitutes the foundation of the technosciences paradigm. New media, technological arts, virtual arts, etc., partake in the dialogue between humans and machines, and thus contribute to the prolongation of this paradigm. Frank Popper nearly called his book “Techno Art” instead of “Virtual Art”, in reference to technosciences (his editor suggested the name change). For artists in the technological arts community, Jakob von Uexkull’s notion of “human-animal milieu” is an essential reference. Also present in Simondon’s reflections on human environments (both natural and artificial), the notion of “milieu” is quite important in the discourses about art and the environment. Concordia University’s artistic community chose the concept of “milieu” as the rallying point of its research laboratories.

ISEA2020’s theme resonates particularly well with the recent eruption of processing and artificial intelligence technologies. For me, Sentience is a purely human and animal idea: machines can only simulate our ways of thinking and feeling. Partly in an effort to explore the illusion of sentience in computers, Louis-Philippe Rondeau, Benoît Melançon and I have established the Mimesis laboratory at NAD University. Processing and AI technologies are especially useful in the creation of “digital doubles”, “Vactors”, real-time avatar generation, Deep Fakes and new forms of personalised interactions.

I adhere to the epistemological position that the living world is immeasurable. Through their ability to simulate, machines can merely reduce complex logics to a point of understandability. The utopian notion of empathetic computers is an idea mostly explored by popular science-fiction movies. Nonetheless, research into computer sentience allows us to devise possible applications, explore notions of embodiment and agency, and thereby develop new forms of interaction. Beyond my own point of view, the idea that machines can somehow feel emotions gives artists and researchers the opportunity to experiment with certain findings from the fields of the cognitive sciences, computer sciences and interactive design. For example, in 2002 I was particularly marked by an immersive installation at Universal Exhibition in Neuchatel, Switzerland titled Ada: Intelligence Space. The installation comprised an artificial environment controlled by a computer, which interacted with the audience on the basis of artificial emotion. The system encouraged visitors to participate by intelligently analysing their movements and sounds. Another example, Louis-Philippe Demers’ Blind Robot (2012),  demonstrates how artists can be both critical of, and amazed by, these new forms of knowledge. Additionally, the 2016 BIAN (Biennale internationale d’art numérique), organized by ELEKTRA (Alain Thibault) explored the various ways these concepts were appropriated in installation and interactive art. The way I see it, current works of digital art operate as boundary objects. The varied usages and interpretations of a particular work of art allow it to be analyzed from nearly every angle or field of study. Thus, philosophers can ask themselves: how does a computer come to understand what being human really is?

I have yet to attend conferences or exchange with researchers on that subject. Although the sheer number of presentation propositions sent to ISEA2020, I have no doubt that the symposium will be the ideal context to reflect on the concept of Sentience and many issues raised therein.

For the last bit of news.

HotPopRobot, one of six global winners of 2020 NASA SpaceApps COVID-19 challenge

I last wrote about HotPopRobot’s (Artash and Arushi with a little support from their parents) response to the 2020 NASA (US National Aeronautics and Space Administration) SpaceApps challenge in my July 1, 2020 post, Toronto COVID-19 Lockdown Musical: a data sonification project from HotPopRobot. (You’ll find a video of the project embedded in the post.)

Here’s more news from HotPopRobot’s August 4, 2020 posting (Note: Links have been removed),

Artash (14 years) and Arushi (10 years). Toronto.

We are excited to become the global winners of the 2020 NASA SpaceApps COVID-19 Challenge from among 2,000 teams from 150 countries. The six Global Winners will be invited to visit a NASA Rocket Launch site to view a spacecraft launch along with the SpaceApps Organizing team once travel is deemed safe. They will also receive an invitation to present their projects to NASA, ESA [European Space Agency], JAXA [Japan Aerospace Exploration Agency], CNES [Centre National D’Etudes Spatiales; France], and CSA [Canadian Space Agency] personnel. https://covid19.spaceappschallenge.org/awards

15,000 participants joined together to submit over 1400 projects for the COVID-19 Global Challenge that was held on 30-31 May 2020. 40 teams made to the Global Finalists. Amongst them, 6 teams became the global winners!

The 2020 SpaceApps was an international collaboration between NASA, Canadian Space Agency, ESA, JAXA, CSA,[sic] and CNES focused on solving global challenges. During a period of 48 hours, participants from around the world were required to create virtual teams and solve any of the 12 challenges related to the COVID-19 pandemic posted on the SpaceApps website. More details about the 2020 SpaceApps COVID-19 Challenge:  https://sa-2019.s3.amazonaws.com/media/documents/Space_Apps_FAQ_COVID_.pdf

We have been participating in NASA Space Challenge for the last seven years since 2014. We were only 8 years and 5 years respectively when we participated in our very first SpaceApps 2014.

We have grown up learning more about space, tacking global challenges, making hardware and software projects, participating in meetings, networking with mentors and teams across the globe, and giving presentations through the annual NASA Space Apps Challenges. This is one challenge we look forward to every year.

It has been a fun and exciting journey meeting so many people and astronauts and visiting several fascinating places on the way! We hope more kids, youths, and families are inspired by our space journey. Space is for all and is yours to discover!

If you have the time, I recommend reading HotPopRobot’s August 4, 2020 posting in its entirety.

First major literary work (Chaucer’s Canterbury Tales) developed as an app

I wanted something completely different today and found it in a May 2, 2020 article, by Lucie Laumonier for University Affairs, about a multimedia app featuring the Canterbury Tales narrated in middle English,

Four historians from Canada and England have launched the General Prologue app, the first app featuring an audio performance of Geoffrey Chaucer’s The Canterbury Tales in its original 14th-century English.

“Here bygynneth the Book of the tales of Caunterbury,” says the expressive voice of the narrator. The strange Middle English words comprise the opening verse of the medieval masterpiece composed by Chaucer more than 600 years ago. The app, which launched on February 3, is available for iOS and Android users, and through a dedicated website.

A February 2, 2020 University of Saskatchewan news release (also on EurekAlert), announced news of the app’s launch and the international collaboration, which included an academic at University College London (UCL), and the late Terry Jones (of Monty Python fame),

A University of Saskatchewan-led international team has produced the first web and mobile phone app of Geoffrey Chaucer’s The Canterbury Tales–the first major literary work augmented by new scholarship, in any language, presented in an app.

“We want the public, not just academics, to see the manuscript as Chaucer would have likely thought of it–as a performance that mixed drama and humor,” said University of Saskatchewan (USask) English professor Peter Robinson, leader of the project.

“We have become convinced, over many years, that the best way to read the Tales is to hear it performed–just as we imagine that Chaucer himself might have performed it at the court of Richard II.”

The free app is the first edition in a planned series. The app features a 45-minute audio performance of the General Prologue of the Tales–the masterpiece work by the most important English writer before Shakespeare–along with the digitized original manuscript. While listening to the reading, users have access to supporting content such as a translation in modern English, commentary, notes and vocabulary explaining Middle English words used by Chaucer.

The app, an offshoot of Robinson’s 25-year work to digitize the Canterbury Tales, contains key new research work. This includes a new edited text of the Prologue created by USask sessional lecturer Barbara Bordalejo, a new reading of the Tales by former USask student Colin Gibbings, and new findings about the Tales by UCL (University College London) medievalist professor Richard North. The National Library of Wales offered its digitized version of the Prologue‘s original manuscript for the app.

The late Monty Python star Terry Jones, who was a medievalist with two influential books on Chaucer, was also instrumental in developing the content of the app. His translation of The General Prologue and his books feature in the introduction and notes. This work on the app is thought to have been the last major academic project that Jones worked on before his passing on January 21.

The app was released on Android and Apple IoS just after Jones’ birthday on February 1st, in celebration of Jones’ academic work.

“We were so pleased that Terry was able to see and hear this app in the last weeks of his life. His work and his passion for Chaucer was an inspiration to us,” said Robinson, whose work on the Tales has been supported by USask and by the federal Social Sciences and Humanities Research Council (SSHRC). “We talked a lot about Chaucer and it was his idea that the Tales would be turned into a performance.”

Because Chaucer left the Tales unfinished at his death, there is no single text of the Tales, and scholars have to re-construct the text from over 80 distinct manuscripts, mostly written by hand before 1500.

“While the app has material which should be of interest to every Chaucer scholar, it is particularly designed to be useful to people reading Chaucer for the first time. These include not only bachelor of arts university students and school children but also members of the public who have their own interest in Chaucer and his works,” said UCL’s North.

Robinson’s Canterbury Tales project, based at USask since 2010, includes several students who are transcribing all 30,000 pages of the manuscripts into the computer to discover how they are related to each other and to Chaucer’s lost original.

“The app is important for people who do not know the history behind the production of the Canterbury Tales, and to understand how the modern concept of author didn’t exist back then,” said Robinson. “We have many manuscripts copied by hand over time, and the Canterbury Tales Project hopes to establish where they come from, how they were created and who produced them as part of that history.”

Robinson said that the team has ready materials to develop at least two more apps, in particular Miller’s Tale, the second story in the Canterbury Tales.

The General Prologue app was built around the Hengwrt manuscript of the Tales, commonly regarded as the best source for Chaucer’s text and held at The National Library of Wales. The specialist preservation and digitization work undertaken at The National Library of Wales enabled the images of the original manuscript to be presented with supporting content for readers via the app.

North’s academic research on the project includes several new discoveries. For instance, he has found evidence suggesting that Chaucer’s Knight, one of the main characters of the Tales, is at the siege of Algeciras near Gilbraltar, in the south of Spain, in 1369 instead of the commonly assumed date 1342-44.

North believes that putting the Knight at this siege puts his age nearer to 50 years old when the reader encounters him with the other pilgrims in the Tabard in the General Prologue–about the age of Chaucer himself.

Brigit Katz covered the story in a February 5, 2020 article for Smithsonian Magazine. Medievallists.net also posted a story (no date) which included two trailers for the app (you’ll find a 1:39 trailer below),

Here’s where you’ll find the app and more,

Enjoy! And for those who caught it, “something completely different” was a reference to Monty Python’s “And Now for Something Completely Different.”

Creative destruction for Canada’s fundamental science

After receiving an ‘invitation’ from the Canadian Science Policy Centre, I wrote an opinion piece, drawing on my submission for the public consultation on Canada’s fundamental science research. It seems the invitation was more of a ‘call’ for submissions and my piece did not end up being selected for inclusion on the website. So rather than waste the piece, here it is,

Creative destruction for Canada’s fundamental science

At a time when we are dealing with the consequences of our sins and virtues, fundamental science, at heart, an exercise in imagination, can seem a waste of precious time. Pollution and climate change (sins: ill-considered uses of technology) and food security and water requirements (virtues: efforts to improve health and save more lives) would seem to demand solutions not the flights of fancy associated with basic science. After all, what does the ‘big bang’ have to do with potable water?

It’s not an unfair question despite the impatience some might feel when answering it by citing a number of practical applications which are the result of all that ‘fanciful’ or ‘blue sky’ science. The beauty and importance of the question is that it will always be asked and can never be definitively answered, rendering it a near constant goad or insurance against complacency.

In many ways Canada’s review of fundamental science (deadline for comments was Sept. 30, 2016) is not just an examination of the current funding schemes but an opportunity to introduce more ‘goads’ or ‘anti-complacency’ measures into Canada’s fundamental science efforts for a kind of ‘creative destruction’.

Introduced by economist Joseph Schumpeter, the concept is derived from Karl Marx’s work but these days is associated with disruptive, painful, and regenerative innovation of all kinds and Canadian fundamental science needs more ‘creative destruction’. There’s at least one movement in this direction (found both in Canada and internationally) which takes us beyond uncomfortable, confrontative questions and occasional funding reviews—the integration of arts and humanities as an attempt at ‘creative destruction’ of the science endeavour.

At one point in the early 2000s, Canada developed a programme where the National Research Council could get joint funding with the Canada Council for the Arts for artists to work with their scientists. It was abandoned a few years later, as a failure. But, since then, several informal attempts at combining arts, sciences, and humanities have sprung up.

For example, Curiosity Collider (founded in 2015) hosts artists and scientists presenting their art/science pieces at various events in Vancouver. Beakerhead has mashed up science, engineering, arts, and entertainment in a festival founded and held in Calgary since 2013. Toronto’s ArtSci Salon hosts events and installations for local, national, and international collaborations of artists and scientists. And, getting back to Vancouver, Anecdotal Evidence is a science storytelling series which has been appearing sporadically since 2015.

There is a tendency to dismiss these types of collaboration as a form of science outreach designed to amuse or entertain but they can be much more than that. Illustrators have taught botanists a thing or two about plants. Markus Buehler at the Massachusetts Institute of Technology has used his understanding of music to explore material science (spider’s webs). Domenico Vicinanza has sonified data from space vehicle, Voyager 1, to produce a symphony, which is also a highly compressed means of communicating data.

C. P. Snow’s ‘The Two Cultures’ (lecture and book) covered much of the same territory in 1959 noting the idea that the arts and sciences (and humanities) can and should be linked in some fashion was not new. For centuries the sciences were referred to as Natural Philosophy (humanities), albeit only chemistry and physics were considered sciences, and many universities have or had faculties of arts and sciences or colleges of arts and science (e.g., the University of Saskatchewan still has such a college).

The current art/sci or sci-art movement can be seen as more than an attempt to resuscitate a ‘golden’ period from the past. It could be a means of embedding a continuous state of regeneration or ‘creative destruction’ for fundamental science in Canada.

Silicene in Saskatchewan (Canada)

There’s some very exciting news coming out of the province of Saskatchewan (Canada) about silicene, a material some view as a possible rival to graphene (although that’s problematic according to my Jan. 12, 2014 posting) while others (US National Argonne Laboratory) challenge its existence (my Aug. 1,  2014 posting).

The researchers in Saskatchewan seem quite confident in silicene’s existence according to a Sept. 9, 2014 news item on phys.org,

“Once a device becomes too small it falls prey to the strange laws of the quantum world,” says University of Saskatchewan researcher Neil Johnson, who is using the Canadian Light Source synchrotron to help develop the next generation of computer materials. Johnson is a member of Canada Research Chair Alexander Moewes’ group of graduate students studying the nature of materials using synchrotron radiation.

His work focuses on silicene, a recent and exciting addition to the class of two-dimensional materials. Silicene is made up of an almost flat hexagonal pattern of silicon atoms. Every second atom in each hexagonal ring is slightly lifted, resulting in a buckled sheet that looks the same from the top or the bottom.

A Sept. 9, 2014 Canadian Light Source news release, which originated the news item, provides background as to how Johnson started studying silicene and some details about the work,

In 2012, mere months before Johnson began to study silicene, it was discovered and first created by the research group of Prof. Guy Le Lay of Aix-Marseille University, using silver as a base for the thin film. The Le Lay group is the world-leader in silicene growth, and taught Johnson and his colleagues how to make it at the CLS themselves.

“I read the paper when the Le Lay announced they had made silicene, and within three or four months, Alex had arranged for us to travel down to the Advanced Light Source with these people who had made it for the first time,” says Johnson. It was an exciting collaboration for the young physicist.

“This paper had already been cited over a hundred times in a matter of months. It was a major paper, and we were going to measure this new material that no one had really started doing experiments on yet.”

The most pressing question facing silicene research was its potential as a semiconductor. Today, most electronics use silicon as a switch, and researchers looking for new materials to manage quantum effects in computing could easily use the 2-D version if it was also semiconducting.

Calculations had shown that because of the special buckling of silicene, it would have what’s called a Dirac cone – a special electronic structure that could allow researchers to tune the band gap, or the energy space between electron levels. The band gap is what makes a semiconductor: if the space is too small, the material is simply a conductor. Too large, and there is no conduction at all.

Since silicene has only ever been made on a silver base, the materials community also wondered if silicene would maintain its semiconducting properties in this condition. Though its atomic structure is slightly different than freestanding silicene, it was still predicted to have a band gap. However, silver is a metal, which may make the silicene act as a metal as well.

No one really knew how silicene would behave on its silver base.

To adapt the Le Lay group’s silicene-growing process to the equipment at the CLS took several days of work. Though their team had succeeded in silicene synthesis at the Advanced Light Source at Berkeley lab, they had no way to keep those samples under vacuum to prevent them from oxygen damage. Thanks to the work of fellow beamteam members Drs. David Muir and Israel Perez, samples grown at the CLS could be produced, transported and measured in a matter of hours without ever leaving a vacuum chamber.

Johnson grew the silicene sheets at the Resonant Elastic and Inelastic X-ray Scattering (REIXS), beamline, then transferred them in a vacuum to the XAS/XES endstation for analysis. Finally, Johnson could find the answer to the silicene question.

“I didn’t really know what to expect until I saw the XAS and XES on the same energy scale, and I thought to myself, that looks like a metal,” says Johnson.

And while that result is unfortunate for those searching for a new computing wonder material, it does provide some vital information to that search.

“Our result does help to guide the hunt for 2-D silicon in the future, suggesting that metallic substrates should be avoided at all costs,” Johnson explains. “We’re hopeful that we can grow a similar structure on other substrates, ideally ones that leave the semiconducting nature of silicene intact.”

That work is already in process, with Johnson and his colleagues planning to explore three other growing bases this summer, along with multilayers and nanoribbons of silicene.

Like the Dutch researchers in the Jan. 12, 2014 posting, Johnson finds that silicene is not serious competition for graphene (as regards to its electrical properties), but he does not challenge its existence. He does note problems with the silver substrate although he comes to a different conclusion than did the Argonne National Laboratory researchers (Aug. 1,  2014 posting).
