August Section/EMB Joint Meeting

"Machine Learning in Digital Medicine"

AI in DIgital Medison

    • Wednesday, August 14th, 3:30 PM to 5:00 PM
    • Dr. Georgio Quer, Sr. Research Scientist at the Scripps Research (SR) in San Diego
    • Location:
      Madison Central Library
      201 W. Mifflin St., Madison WI 53703
    • Conference Room 104

 

Talk: Digitalize human beings using biosensors to track our complex physiologic system, process the large amount of data generated with artificial intelligence (AI) and change clinical practice towards individualized medicine: these are the goals of digital medicine. At Scripps, we are a team of computer scientists, engineers, and clinical researchers, in partnership with health industries, and we propose new solutions to analyze large longitudinal data using statistical learning and deep convolutional neural networks to address different cardiovascular health issues.

One of the greatest contributors to premature mortality worldwide is hypertension. Lowering blood pressure (BP) by just a few mmHg can bring substantial clinical benefits, but it is hard to assess the “true” BP for an individual, since it fluctuates significantly. With a dataset of 16 million BP measurements, we unveil the BP patterns and provide insights on the clinical relevance of these changes.

Another prevalent health issue is atrial fibrillation (AF), the most common sustained cardiac arrhythmia, associated with stroke, heart failure and coronary artery disease. AF detection from single-lead electrocardiography (ECG) recordings is still an open problem, as AF events may be episodic and the signal noisy. We conduct a thoughtful analysis of recent convolutional neural network architectures developed in the computer vision field, redesigned to be suitable for a one-dimensional signal, and we evaluate their performance in the detection of AF using 200 thousand seconds of ECG, highlighting the potential and pitfall of this technology.

Looking to the future, we investigate new applications for wearable devices and advanced processing in the All of Us Research Program, an unprecedented research effort to gather data from one million people in the USA to accelerate the advent of precision medicine.

September Section Meeting

"LENR What the ...."

New Fire

    • Wednesday, September 4th, 5:30 PM to 7:00 PM
    • Bob Greenyer, Martin Fleischmann Memorial Project
    • Location:
      Science Hall
      550 North Park St., Madison WI 53703
    • Lecture Hall 180

 

Talk: When you think you know how things work and then you not only witness, but recognize something as being so far from what is generally expected, that it shocks you to the core, what would you do? Would you let your scientific curiosity become a life-long search for the answer? Could you let it pass you by and carry on the mundane treadmill of the path often traveled? What would make a person choose to spend the rest of their life engaged in an activity that to many, would appear pointless and misguided?
Bob Greenyer talks about some of those people that not only knew they were seeing something special, but took it upon themselves to try and understand the observed effects, with an aim to give humanity, against the odds, new tools with which to take us collectively forward.

These people laid the groundwork for what is now becoming a hot research area, one which may define the next millennia and our species long term prospects.

Bio: Bob Greenyer studied manufacturing engineering at Brunel University, West London, during which time he also worked at the Electrical Engineering Department of Smithkline Beecham Pharmaceuticals (now Glaxo-Smithkline) at their largest UK factory which produced Augmentin and conducted primary research including that focussed on anti-bacteria and anti-viral solutions.  During his time there, he updated all of the Electrical Engineering standards documentation, developed a portable system to monitor the over 100 electrical meters on site, helped specify a factory wide modern alarm system and developed a database to track maintenance on the sites 4000 industrial electric motors.
On leaving university he launched his then new media studio and developed cutting edge websites, animations and interactive solutions for a range of industries and FTSE 100 companies. Later he worked at the highest levels of one of the worlds largest international banks, developing all of their major client and investor facing media, analyzing complex data sets and presenting the resulting conclusions in words, graphs and moving images.

This skillset and operation was moved to India where it was intended that the operation would be scaled, however, a combination of the financial crisis and proceduralization of what once was stimulating problem solving led him to explore one of his other greatest passions, the science of energy.

In 2012, he took himself to South Korea to ICCF-17 the semi-annual conference of Condensed Matter Nuclear Science, where he and 4 other like-minded individuals set up the Martin Fleischmann Memorial Project to try and see if a new approach to science could stimulate more engagement in a maligned and poorly understood frontier of energy research.

Since then, he has had the opportunity to converse and work with some of the leaders in this field across the world and be a part of designing, conducting and analyzing a range of experiments both in house and conducted by third parties.

September IAS/PES Meeting: "Optimizing power system operations – Methods to manage the impact of renewable energy on electric grids"

Optimizing Power Grids

    • Monday, September 9th, 530 PM to 7:00 PM
    • Dr. Line A. Roald, UW-Madison ECE Department
    • Location:
      Engineering Hall
      1415 Johnson Street, Madison WI 53706
    • Room 2535

 

Talk: How can transmission system operators ensure secure and reliable operation of the electric grid when renewable energy generation is uncertain? How can rooftop solar PV be a resource rather than a problem when managing voltage unbalance in distribution grids? To answer these and other questions related to renewable energy integration, new tools for power systems operations are required. This presentation will discuss our research aimed at developing such new tools. In particular, we will discuss how data-driven, optimization-based methods can help manage renewable energy variability and harness the flexibility available in the grid.

Bio: Line A. Roald is an Assistant Professor and Grainger Institute for Engineering Fellow in the Department of Electrical and Computer Engineering at the University of Wisconsin – Madison. Prior to joining UW Madison, she obtained her PhD at ETH Zurich in Switzerland and worked as a post-doctoral fellow at Los Alamos National Laboratory in New Mexico. Her research interests include optimization, probabilistic methods and data analytics for electric power systems.

October Joint Section/EMB Meeting: "Tuning magnetic anisotropy in nanostructures for biomedical applications"

Optimizing Power Grids

    • Friday, October 25th, Noon (TBD)
    • Dr. Hari Srikanth. Dept. of Physics, University of South Florida
    • Location:
      Engineering Hall
      1415 Johnson Street, Madison WI 53706
    • Room TBD

 

Talk: Magnetic nanoparticles have been building blocks in applications ranging from high density recording to spintronics and nanomedicine.  Magnetic anisotropies in nanoparticles arising from surfaces, shapes and interfaces in hybrid structures are important in determining the functional response in various applications. In this talk I will first introduce the basic aspects of anisotropy, how to tune it in nanostructures and ways to measure it. I will discuss resonant RF transverse susceptibility, that we have used extensively, as a powerful method to probe the effective anisotropy in magnetic materials. Tuning anisotropy has a direct impact on the performance of functional magnetic nanoparticles in biomedical applications such as contrast enhancement in MRI and magnetic hyperthermia cancer therapy. There is a need to improve the specific absorption rate (SAR) or heating efficiency of nanoparticles for hyperthermia and I will focus on the role of tuning surface and interfacial anisotropy with a goal to enhance SAR. Strategies going beyond simple spherical structures such as exchange coupled core-shell nanoparticles, nanowire, nanotube geometries can be exploited to increase saturation magnetization, effective anisotropy and heating efficiency in magnetic hyperthermia. This lecture will combine insights into fundamental physics of magnetic nanostructures along with recent research advances in their application in nanomedicine.

Review of July International Future Energy Challenge 2019 Event

Nine finalists in the International Future Energy Challenge 2019 Student competition arrived in Madison on Sunday, July 28th with their E-Bike Controllers in hand and with high hopes to win the $10,000 first prize.  On successive days, the teams put their controllers through a series of talks and tests while the judges looked on and kept score.  Here is a summary of what they went through:

Monday, July 29th:  After a tour of the Grainger Maker Space at UW-Madison, each student student group gave a short "elevator speech" touting the best aspects of their designs.  They also published a specification sheet that was evaluated by a team of judges.  Competitors and support teams were given a food pass for lunch at Union South. Each group in turn, picked in random order, connected their controller to a standard supply and motor/load for a series of bench tests. The first test were simple "Functional" tests, verifying that E-Stops or Brake inputs disabled the drive.  Also, did the LED correctly blink for low battery, or other fault conditions.

Tuesday, July 30th:  This day began a series of more difficult tests that included rotating the motor and assessing operational performance and overall efficiency under different load conditions. Before other tests, they had to pass a Hi-Pot leakage test from battery leads to the controller case of 250 VAC.  The first operational test was a no-load, "chain off" test that simulated a fault condition where the motor either stopped at a maximum RPM, or faulted after exceeding the maximum RPM condition.  They then had to pass an efficiency test with three separate loads and three separate commanded speeds.  Finally, the last functional bench test was a simulated hill climb for 30 seconds.

Wednesday, July 31st: The top five teams (some did not pass all of the required tests) got to strap their controller on a Trek provided bike with the test motor mounted and run a 8-lap timed track partitioned with track guards provided by Saris.  Four members of the team had to participate, each taking two laps with fast changes in between. The timed trials ended at 2:00 PM and the teams attend the final awards banquet that evening.

The UW-Madison WEMPEC Faculty Kyle M Hanson andGiri Venkataramanan did a exceptional job organizing the event and their student support provided needed help fo all of the teams to repair, tune, and test the controllers.  IEEE-Madison volunteers Hugh Schmidt, Tom Kaminski, Don Neumeyer and Thomas Murphy also provided much needed support during the setup and testing phases.
