Abstract (Talk 1):

MACHINE LEARNING IN DIGITAL MEDICINE

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 promote a strong collaboration between computer scientist, engineers, and clinical researchers, as well as a direct partnership with health industry leaders. We propose new solutions to analyze large longitudinal data using statistical learning and deep convolutional neural networks to address different cardiovascular health issues. Among them, one of the greatest contributors to premature morbidity and mortality worldwide is hypertension. It is known that lowering blood pressure (BP) by just a few mmHg can bring substantial clinical benefits, but the assessment of the “true” BP for an individual is non-trivial, as the individual BP can fluctuate significantly. We analyze a large dataset of more than 16 million BP measurements taken at home with commercial BP monitoring devices, in order to unveil the BP patterns and provide insights on the clinical relevance of these changes.

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

 

Abstract (Talk 2)

CELLULAR DEVICE-TO-DEVICE NETWORKS COEXISTENCE

Looking to the future, we are investigating new applications of existing wearable devices, requiring advanced processing and clinical validation, and we are participating to 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.

The coexistence of device-to-device (D2D) and cellular communications in the same band is a promising solution to the dramatic increase of wireless networks traffic load. Mobile nodes may communicate in a semi-autonomous way (D2D mode), with minimal or no control by the base station (BS), but they will create a harmful interference to the cellular communications.

To control this interference, we propose a distributed approach that allows the mobile nodes to acquire local information in real time, infer the impact on other surrounding communications towards the BS, and optimize mode and power selection performed with a network wide perspective. In a single-cell scenario, we develop a rigorous theoretical analysis to quantify the balance between the gain offered by a D2D transmission and its impact on the cellular network communications, while in a multi-cell scenario, we exploit a probabilistic approach with Bayesian networks.

As a practical application, we envision a network with one macro BS, multiple small cell BSs, and several mobile D2D users, where proactive caching can be used to take full advantage of this heterogeneity. In this scenario, we propose a robust optimization framework to derive a proactive caching policy that exploits all these communication opportunities and reduces congestion on the backhaul link.

The adoption of D2D technologies may save precious resources like spectrum and energy for future 5G networks by exploiting physical proximity between terminals, helping to counteract the increasing traffic demand in cellular networks.

Abstract: Wireless communication technologies are ubiquitous nowadays. Most of the smart devices have Cellular, Wi‐Fi, Bluetooth connections. These technologies have been developed for many years, nonetheless they are still being enhanced. More development can be expected in the next 5 years, such as faster transmission data rate, more efficient spectrum usage, lower power consumption, etc. Similarly, cellular networks have evolved for several generations. For example, GSM as part of 2G family, UMTS as part of the 3G family, and LTE as part of 4G family. In the next few years, 5G cellular network systems will continue the evolution to keep up with the fast‐growing needs of customers. Secure wireless communications will certainly be part of other advances in the industry such as multimedia streaming, data storage and sharing in clouds, mobile cloud computing services, etc. This talk covers the topics on security for next generation mobile wireless networks, with focusing on 5G mobile wireless network systems, followed by a discussion on the challenges and open research issues in the area.

Abstract: Surgery developed in human history as a highly skilled activity to treat a wide variety of ailments.  Its effectiveness has increased dramatically over the centuries as our understanding of anatomy, physiology and the course of diseases has deepened.  While medical advances still contribute to improvements in surgical procedures, we have now reached a new stage where engineering and computational methods are contributing to significant improvements in surgical outcomes. This new development has the potential to also change the nature of ailments that surgery can help.  Underlying this progress are development in imaging technology which have contributed both to better diagnostic capabilities and to better therapeutic procedures, particularly in the field of image-guided surgery.  In this presentation, a number of technological developments that have contributed to improvements in surgery will be presented and analyzed.

Speaker Bio: Dr. Hartov was born in France and moved to the US where he attended university.  He graduated with a BSEE (Bachelor of Science in Electrical Engineering) from Northeastern University in 1984, and obtained his MS and PhD from the Thayer School of Engineering at Dartmouth in 1988 and 1991 respectively.  He was invited to join the Thayer School research faculty in 1996 where he worked on the development of electrical impedance tomography for breast cancer screening.  Dr. Hartov also worked in collaboration with neurosurgeons on the development of apparatus and algorithms used in imaged surgery and is named as an inventor on several related patents.
