//The clinical study, which began in May 2018, will involve more than 800 women from Calgary and Edmonton, and roughly 600 women in Manchester, U.K.
Participants are given a simple blood test along with their regular mammogram.
“The earlier you can identify the breast cancer at a point that it’s treatable, the better the outcomes,” said Kristina Rinker, associate professor of bioengineering at the University of Calgary.
According to Rinker, a computer algorithm allows scientists to identify a molecular marker for active breast cancer in the blood at an early stage. She says 800 samples — already collected — show the test has an accuracy rate of about 90 per cent.
“Finding it early, finding it at stage one, getting the treatment as fast as possible, that’s going to save lives,” she said.
Rinker hopes the blood test will eventually be used along with mammography to help identify cancer in women who have dense breast tissue — which makes cancer more difficult to detect — or those who have inconclusive mammogram results.//
20180324 update: For now, I’ve found these two posts by Brad Templeton to be very insightful and cover some of the issues that I want to write about but Brad wrote in much more detail! Have a read, 03/20 “New facts and questions on Uber robocar fatality” & 03/21 “It certainly looks bad for Uber“. I may still add more if I see more facts of the case especially when Uber starts to voluntarily (or be compelled to) provide more of its internal technical data. I hope Uber won’t try to brush this fatality under the carpet. Will see.
From the AP report “Experts: Uber self-driving system should have spotted woman”, this Uber self-driving SUV is using LIDAR laser sensors technology to “see”. (note: LIDAR stands for Light Detection and Ranging and it “measures distance to a target by illuminating the target with pulsed laser light” which can see perfectly well even in total darkness as it uses laser.) I made this observation re LIDAR in direct response to this sentence of the news report, “The lights on the SUV didn’t illuminate 49-year-old Elaine Herzberg on Sunday night until a second or two before impact, raising questions about whether the vehicle could have stopped in time.” And the fact the Uber safety driver was NOT paying attention to the road when he killed the 49-year-old Elaine Herzberg!
““The victim did not come out of nowhere. She’s moving on a dark road, but it’s an open road, so Lidar (laser) and radar should have detected and classified her” as a human, said Bryant Walker Smith, a University of South Carolina law professor who studies autonomous vehicles.
Smith said the video may not show the complete picture, but “this is strongly suggestive of multiple failures of Uber and its system, its automated system, and its safety driver.”
Sam Abuelsmaid, an analyst for Navigant Research who also follows autonomous vehicles, said laser and radar systems can see in the dark much better than humans or cameras and that Herzberg was well within the range.
“It absolutely should have been able to pick her up,” he said. “From what I see in the video it sure looks like the car is at fault, not the pedestrian.”
Smith said that from what he observed on the video, the Uber driver appears to be relying too much on the self-driving system by not looking up at the road.
“The safety driver is clearly relying on the fact that the car is driving itself. It’s the old adage that if everyone is responsible no one is responsible,” Smith said. “This is everything gone wrong that these systems, if responsibly implemented, are supposed to prevent.”
The experts were unsure if the test vehicle was equipped with a video monitor that the backup driver may have been viewing.
Uber immediately suspended all road-testing of such autos in the Phoenix area, Pittsburgh, San Francisco and Toronto. The National Transportation Safety Board, which makes recommendations for preventing crashes, is investigating the crash.”
I will try to come back to this article and add more details and updates in the coming days when I have more time. Will see.
Dr. Matt Blaze’s House testimony on the security of voting machines.
#VotingMachines #eVoting It worries me that some form of e-voting was used in last Calgary municipal elections and more are being studied to be potentially used in the future. (Case of I don’t know enough.) As someone who has been following e-voting and development of secure voting machines for decades (a company I used to work for had a team that develop e-voting system), I have my serious reservations with e-voting and voting machines and want all levels of Canadian governments (city, provincial, federal) to study slow and proceed very very very carefully!
To learn more, I’m watching UPenn’s Dr. Matt Blaze‘s House testimony on the security of voting machines.
The Deep Learning Summit took place in Montreal on 10-11 October 2017 and brought together global AI pioneers including: Yoshua Bengio, Yann LeCun, and Geoffrey Hinton, as well as experts from companies including Intel, NVIDIA, Twenty Billion Neurons and Apple.

“A team of U of T engineering researchers is mending broken hearts with an expanding tissue bandage a little smaller than a postage stamp.
Repairing heart tissue destroyed by a heart attack or medical condition with regenerative cells or tissues usually requires invasive open-heart surgery. But now biomedical engineering Professor Milica Radisic [K’s note: including links to PubMed listed articles] and her colleagues have developed a technique that lets them use a small needle to inject a repair patch, without the need to open up the chest cavity.
Such lab-grown tissues are already being used to test potential drug candidates for side-effects, but the long-term goal is to implant them back into the body to repair damage.
“If an implant requires open-heart surgery, it’s not going to be widely available to patients,” says Radisic.
She says that after a myocardial infarction – a heart attack – the heart’s function is reduced so much that invasive procedures like open-heart surgery usually pose more risks than potential benefits.
“It’s just too dangerous,” she says.
Miles Montgomery, a PhD candidate in Radisic’s lab, has spent nearly three years developing a patch that could be injected, rather than implanted. [K’s note: more news on Miles]
“At the beginning, it was a real challenge,” he says. “There was no template to base my design on, and nothing I tried was working. But I took these failures as an indication that I was working on a problem worth solving.”
After dozens of attempts, Montgomery found a design that matched the mechanical properties of the target tissue and had the required shape-memory behaviour: as it emerges from the needle, the patch unfolds itself into a bandage-like shape.
The scaffold is built out of the same biocompatible, biodegradable polymer used in the team’s previous creations. Over time, the scaffold will naturally break down, leaving behind the new tissue.
The team also showed that injecting the patch into rat hearts can improve cardiac function after a heart attack: damaged ventricles pumped more blood than they did without the patch.
“It can’t restore the heart back to full health, but if it could be done in a human, we think it would significantly improve quality of life,” says Radisic.
There is still a long way to go before the material is ready for clinical trials. Radisic and her team are collaborating with researchers at the Hospital for Sick Children to assess the long-term stability of the patches, as well as whether the improved cardiac function can be maintained.
They have also applied for patents on the invention and are exploring the use of the patch in other organs, such as the liver.
“You could customize this platform, adding growth factors or other drugs that would encourage tissue regeneration,” says Radisic. “I think this is one of the coolest things we’ve done.”“
According to Demis Hassabis, the CEO and founder of DeepMind, this time out the machine is driven by a new and more powerful architecture. It can now learn the game almost entirely from play against itself, relying less on data generated by humans. In theory, this means DeepMind’s technology can more easily learn any task.“
“Much of that future has yet to play out. And there is no guarantee that AI improves humanity. “In some cases,” grandmaster Gu Li said after a pair game alongside AlphaGo, “I could not follow in his footsteps.” But certainly, DeepMind has effected real change in the world of Go, a game that’s enormously popular across China, Korea, and other parts of Asia, and that is a comforting thing. In at least one way, AI has helped make humans better.
Ke Jie went on to lose that game and then the next. And some observers continued to lament that machines were eclipsing humans. But that’s not the story of AlphaGo’s trip to China. What’s most striking is how closely the players have studied the games played by AlphaGo—and how hungry they are for more. Many have repeatedly called on DeepMind to release the many games that AlphaGo has played in private. They know they can’t beat the machine. But like Thore Graepel, they believe it can make them better.“
Let me make a few things clear. I enjoy cooking with my iPot (Instant Pot). I even admire the inventor/entrepreneur/company that makes iPot (have a read of this enjoyable and insightful 30th Jan, 2017 Globe & Mail news article “Ottawa entrepreneur’s Instant Pot has attracted a devoted following of home cooks“). I think it is awesome to see Canadian inventor/entrepreneur making a name and money from a great product in US, Canada and around the world.
At the same time, I think it is important to point out problems, or design flaws when we see them. Customer feedbacks are good ways for companies to learn to improve their products over time.
I talk about a design flaw for my Instant Pot DUO-60 in the following video. And then I realized Instant Pot had come out with a newly designed DUO-Plus-60 around April 2017 which unfortunately has the same design flaw (based on unboxing video I watched) I identified in the video. It is a bit disappointing the design flaw isn’t fixed with the new DUO-Plus-60.
//Seven years ago Dr. Norman Doidge introduced neuroplasticity to the world – the idea that our brains aren’t rigidly hardwired as was once believed, but that they can change, and can be rewired. Indeed, what is unique about the brain is that its circuits can, through mental experience and activity, form, unform, and reform in new ways.
Now he’s back with a new film, The Brain’s Way of Healing, that will show that not only can the brain change, but that we can use our knowledge of how the brain forms new connections to help it heal in ways we never dreamed possible.
The Brain’s Way of Healing is about neuroplasticity’s next step — healing the brain using totally non-invasive methods, including patterns of energy to resynchronize the brain’s neurons when illness or injury causes them to fire improperly. It’s revolutionary and in some instances shocking — we’ll see people’s lifelong afflictions improved, or, in some cases cured almost miraculously. But these are not miracles, and Dr. Doidge explains the science behind these improvements. […]//
National Music Centre – Studio Bell – 2016 Canada Day Grand Opening
National Music Centre – Studio Bell – 2016 Canada Day Grand Opening
We did something special on 2016 Canada Day in Calgary by attending the grand opening of the National Music Centre (NMC) Studio Bell (Twitter)! Yes, the lineup was long and around the block (~1.5 hours) even at 10am in the morning but it totally worth our time in the wait because of the special guest pxerformances we got to watch (more on this later). Regular admission fees are $18 for adult, $14 for Seniors/Students, $11 for Youth (3-12), free for Children (under 3) and free on this grand opening day. And there is cool as there is a FREE/complimentary admission for “new Canadian citizens within their first year of citizenship. New citizens can apply for the CAP online at www.icc-icc.ca and present their pass upon arrival at Studio Bell for free entry.”

Please see my in-depth video interviews with lead researcher Artee Luchman, PhD, and oncologist Dr. Greg Cairncross (director of SACRI). I’ve also included the press release from the University of Calgary’s Hotchkiss Brain Institute (HBI) and Southern Alberta Cancer Research Institute (SACRI).
//Researchers at the University of Calgary’s Hotchkiss Brain Institute (HBI) and Southern Alberta Cancer Research Institute (SACRI) have made a discovery that could prolong the life of people living with glioblastoma – the most aggressive type of brain cancer. Samuel Weiss, PhD, Professor and Director of the HBI, and Research Assistant Professor Artee Luchman, PhD, and colleagues, published their work today in Clinical Cancer Research, which is leading researchers to start a human phase I/II clinical trial as early as Spring 2015.
The fact that the Charge seems to be using the same faulty 1st generation JBL Flip antenna concerns me greatly. I have enough concerns (just to be safe) that I am issuing a Yellow Flag Caution to tell people be careful and make sure they check their units and see if they have any Bluetooth problems. If you ask me, I would much rather see the more robust 2nd generation Flip antenna being implement and used inside the Charge instead!
Harman JBL might be able to get away with using the faulty 1st generation JBL Flip antenna inside the Charge but I won’t know until I put the Charge under the very rigorous testing performed in KemptonTestLab!
Remember: KemptonTestLab: Only best products pass our tough tests!

Harman JBL Charge antenna – Yellow Flag Caution
3) As usual, I expect the JBL Charge to make great sound like the JBL Flip if you hardwire them. And the spec for the Harman JBL Charge seems quite awesome on the surface quoting the JBL promo document, “10-watt portable stereo speaker with a high-capacity 6,000mAh Li-ion rechargeable battery, a built-in bass port and wireless Bluetooth® connection”
4) Let me point out that if the Charge is playing music directly from the device being charged (e.g. a phone), then the Bluetooth problem is not much of a concern because the transmitting devices (the phone) and the receiver (the Charge speaker) are right next to each other!
March 15th update: I read that YouTube user “6FeetDeep4U”‘s JBL Charge’s Bluetooth seems to be performing very well. I would love to see a test video made (and have suggested that). If 6FeetDeep4U does make a test video and embeddable, I would share it here and possibly revise my comments/”watch” temporarily until I’ve got a chance to find and test a JBL Charge myself in my own KemptonTestLab to benchmark against the other JBL Flips I’ve tested!
After all these years, I still remember the thrill in taking my first year UT Comp. Sci class in 1987 with prof. Cook! And it remains an honour (and bragging right) to have taken the famous third year CSC364 Computability and Complexity class with prof. Cook and seeing him proved to us 3-satisfiability and taught us P v. NP, etc. I am truly excited for prof. Cook!
“What drew you to this field – and to this particular focus? I enrolled as a mathematics graduate student at Harvard in 1961, thinking I’d concentrate in algebra. Computer Science did not yet exist as a discipline. After taking a course in `logic and computation’ from Hao Wang, my future advisor, I switched fields. My PhD thesis was inspired by a question posed by a pioneer in the field named Alan Cobham: Is multiplication (of large numbers) intrinsically harder than addition? Part of the challenge was to formulate this as a precise mathematical question.
Why U of T? I joined the faculty of the computer science department at U of T in 1970. This was one of the world’s first CS departments, and Tom Hull, the department chair, had a powerful vision for its future. He already had recruited some aspiring young faculty, including my close colleague Allan Borodin, who continues to be a pillar of the department. It helped that Toronto is a good sailing venue on Lake Ontario, and sailing was (and is) a major hobby for my wife and me.
What advice would you give to a student just starting out in this field? You’ve made a good choice. The possibilities are boundless.“

This is the second (eps 02) of a series of extensive chats with Professor Emeritus C.C. Kelly Gotlieb, (Wikipedia) “Father of Computing in Canada”, Department of Computer Science, University of Toronto. In this video episode (as oppose to audio recording only in episode #1), we further discussed Google Driverless Cars and Google Glasses in a bit more details, and a few other topics. (I will try to provide a time code key when I have time later or if someone can help me with providing a time code key to the interview.)
P.S. Incidentally, I am happy to claim credit for suggesting Kelly to setup a Google+ account and then also helped him to setup his computer this morning so that we were able to conduct a successful Live Broadcast using the Google+ Hangout On Air technologies using its YouTube engine! It puts a smile on my face in helping the man who helped bought the second electronic computer (a Ferranti machine for $300,000) in the world in 1951 to use Google’s cutting edge technologies to broadcast live from his and my home!
2018 April 19th update: I’m very sad to report the passing of Prof. Kelly Gotlieb on October 16th, 2016 at the age of 95. Have a read of these insightful obits:
This excerpt from the G&M obit really touched me and warmed my heart,
“Kelly and Phyllis Gotlieb had one of the great love affairs. In a 2015 interview, six years after his wife’s death, Dr. Gotlieb said of their relationship: “A scientist who loves poetry and a poet who loves science … It doesn’t get any better than that.” Dr. Gotlieb spent his professional life on the frontier of techno-scientific knowledge, while his wife Phyllis (née Bloom) was an award-winning writer of poetry and speculative fiction who pondered how discoveries such as those of her husband might affect the mind, soul and society of humankind. In their breadth, depth and passion of interests, they were a two-person university.
One of her books of verse was a compilation of love poems sent to her husband over more than 60 years of marriage. The publication of Phyllis Loves Kelly [downloadable via this U of T library page] marked their diamond wedding anniversary in June, 2009; six weeks later she died suddenly at the age of 83. His epitaph to her was: She Graced This World/And Imagined Others. Her tribute to him lies in her final volume of poetry, where she compares herself to the famous fictional cat created by American humourist Don Marquis:
If like a tom and tab we sometimes hiss and scratch and jab I’m still from here to Heaven or Hell your favourite Mehitabel“
