Talk Title: An Update to Biomechanical and Biochemical Principles of Retinal Hemorrhage in Abusive Head Trauma and Other forms of Trauma
Abstract: Our investigation delves into the occurrence of retinal hemorrhages (RH) in pediatric cases stemming from diverse traumatic sources, employing both animal ocular specimens and a computational ocular model. The primary focus is to discern stress distribution patterns arising from linear and angular accelerations, as well as simulate the repetitive shaking experienced by infants. Sclerotomy apertures were meticulously created in the eyes of sheep and primates to expose the retinal tissue, facilitating the measurement of requisite tension stress for retinal separation via nanofiber manipulation. Additionally, a finite element model simulating the pediatric ocular structure was utilized to anticipate tension stress levels during instances of shaking simulating abusive head trauma. Our observations demonstrated that RH can manifest at stress magnitudes akin to those observed in animal eye experimentation during episodes of multiple shaking. Particularly, angular acceleration is implicated in generating concentrated and robust stress gradients along the retinal vasculature, while linear acceleration elicits comparatively milder and more diffused stress patterns towards the posterior ocular pole. Furthermore, employing a multicenter dataset featuring RH images of varying etiologies, we developed an artificial intelligence tool capable of ascertaining the underlying cause of RH. This tool holds potential to aid clinicians in determining the etiology behind cases of RH.

Talk Title: Interpretable multimodal deep learning with application to brain imaging and genomics data fusion
Abstract: Deep network-based data fusion models have been developed to integrate complementary information from multi-modal datasets while capture their complex relationships. This is particularly useful in biomedical domain, where multi-modal data such as imaging and multi-omics are ubiquitous and the integration of these heterogenous data can lead to novel biological findings. However, deep learning models are often difficult to interpret, bringing about challenges for uncovering biological mechanisms using these models. In this work, we develop an interpretable multimodal deep learning-based fusion model to perform automated disease diagnosis and result interpretation simultaneously. We name it Grad-CAM guided convolutional collaborative learning (gCAM-CCL), which is achieved by combining intermediate feature maps with gradient-based weights in a multi-modal convolution network. The gCAM-CCL model can generate interpretable activation maps to quantify pixel-level contributions of the input fMRI imaging features. Moreover, the estimated activation maps are class-specific, which can therefore facilitate the identification of imaging biomarkers underlying different populations such as age, gender and cognitive groups. Finally, we apply and validate the gCAM-CCL model in the study of brain development with integrative analysis of multi-modal brain imaging and genomics data. We demonstrate its successful application to both the classification of cognitive function groups and the discovery of underlying genetic mechanisms.
Biography: Dr. Yu-Ping Wang received the BS degree in applied mathematics from Tianjin University, China, in 1990, and the MS degree in computational mathematics and the PhD degree in communications and electronic systems from Xi'an Jiaotong University, China, in 1993 and 1996, respectively. After his graduation, he had visiting positions at the Center for Wavelets, Approximation and Information Processing of the National University of Singapore and Washington University Medical School in St. Louis.

ECE Seminar: Large-scale data archives and AI methods to study neurological disorders
Tue, Sep 12, 2023 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dominique Duncan, Assistant Professor, USC Stevens Neuroimaging and Informatics Institute, Keck School of Medicine of USC
Talk Title: Large-scale data archives and AI methods to study neurological disorders
Abstract: The Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx) is a multi-site, international collaboration including a parallel study of humans and an animal model, collecting MRI, EEG, and blood samples. The development of epilepsy after traumatic brain injury (TBI) is a multifactorial process and crosses multiple modalities. Without a full understanding of the underlying biological effects, there are currently no cures for epilepsy. This study aims to address both issues, calling upon data generated and collected at sites spread worldwide among different laboratories, clinical sites, in different formats, and across multicenter preclinical trials. Before these data can even be analyzed, a central platform is needed to standardize these data and provide tools for searching, viewing, annotating, and analyzing them. We have built a centralized data archive that will allow the broader research community to access these shared data as well as artificial intelligence (AI) methods and other analytic tools to identify biomarkers of epileptogenesis in imaging, electrophysiology, molecular, serological, and tissue data. In addition to EpiBioS4Rx, we have also developed other large-scale multimodal data archives, including the Data Archive for the BRAIN Initiative (DABI) and the COVID-19 Data Archive (COVID-ARC) to encourage collaboration and expedite research in these areas.
Biography: Dominique Duncan is an assistant professor of Neurology, Neuroscience, and Biomedical Engineering at the USC Stevens Neuroimaging and Informatics Institute in the Laboratory of Neuro Imaging (LONI) at the University of Southern California. Dr. Duncan's background spans mathematics, engineering, and neuroscience. She received her PhD at Yale University in Electrical Engineering where she analyzed intracranial EEG data using nonlinear factor analysis to identify preseizure states of epilepsy patients. Dr. Duncan is funded through both the National Institutes of Health (NIH) and the National Science Foundation (NSF). She has built international, multidisciplinary collaborations and developed novel analytic tools to analyze multimodal data, including imaging and electrophysiology, particularly in the areas of traumatic brain injury, epilepsy, and COVID-19. By creating large-scale data repositories and linking them with analytic, visualization, and quality control tools for multimodal data, her work aims to encourage collaboration across multiple fields.

Talk Title: Hemodynamic Mechanisms of Heart-Aorta-Brain Coupling: From Fluid Dynamics to Advanced Diagnostics and Therapeutics
Abstract: The circulatory system operates based on a delicate hemodynamic balance between the heart, the aorta (the largest vessel that extends from the heart), and major physiological organs, such as the brain and kidneys. Optimal hemodynamic coupling between these organs can be impaired due to aging and/or diseases. Therefore, understanding the complex fluid dynamic coupling (hemodynamic interactions) between the heart, aorta, and brain is crucial for the diagnostics and therapeutics of related diseases, such as heart failure (HF), dementia, and myocardial infarction (heart attack). The general hypothesis is that wave dynamics in the aorta dominate the pulsatile hemodynamics of the heart and brain, as well as the nonlinear interaction between the two. This talk will elucidate the systems-level effects of aortic hemodynamics on heart-brain interactions. Our long-term goal is to transform our findings into the development of diagnostic, therapeutic, and monitoring devices for heart diseases and vascular brain damage.
Biography: Dr. Pahlevans research brings physics and mathematics tools to the study of biological systems ranging from understanding the biomechanics of cardiovascular and cerebrovascular diseases to modeling physiological systems. His ultimate goal in each research initiative is to use mathematical and mechanical engineering principles to establish new techniques and/or devices that are relevant for practicing clinicians. Dr. Pahlevan completed his undergraduate degree in Mechanical Engineering from the University of Tehran, his M.S. in Mechanical Engineering from the California State University Northridge, and PhD in Bioengineering from the California Institute of Technology (Caltech). He completed his postdoctoral training in hemodynamics and cardiovascular imaging at Caltech and Huntington Medical Research Institutes (HMRI) as a Boswell fellow. Dr. Pahlevan joined USC in 2017 as an Assistant Professor of Aerospace and Mechanical Engineering in the Viterbi School of Engineering and Assistant Professor of Medicine in the Division of Cardiovascular Medicine. He is the recipient of both the NSF CAREER Award and the American Heart Association Career Development Award.

Talk Title: Extending the Reach of Quantum Computers via Noise Tailoring
Series: Quantum Science & Technology Seminar Series
Abstract: Noise processes limit the coherence of quantum processors, and therefore limit the number of quantum logical gate operations that can be performed in a single computation. Common error types include coherent errors where the purity of a quantum state is preserved but the phase is scrambled, and stochastic errors where information is lost to an inaccessible environment, resulting a statistical mixture. Though somewhat counterintuitive, coherent errors are typically more pernicious and accumulate faster during a quantum computation. By tailoring coherent errors into stochastic ones, we extend the circuit depth of quantum chemistry and nuclear physics simulations that can be performed on current superconducting quantum processing units.
Biography: Irfan Siddiqi is a Professor of Physics and Department Chair at the University of California, Berkeley. He is also a Professor of Electrical Engineering & Computer Science, and holds a faculty scientist position at Lawrence Berkeley National Laboratory (LBNL). Siddiqi is currently the director of the Quantum Nanoelectronics Laboratory at UC Berkeley and the Advanced Quantum Testbed at LBNL. Siddiqi is known for contributions to the fields of superconducting quantum circuits, including dispersive single-shot readout of superconducting quantum bits, quantum feedback, observation of single quantum trajectories, and near-quantum limited microwave frequency amplification.

Valley Jr. Prize in 2006 "for the development of the Josephson bifurcation amplifier for ultra-sensitive measurements at the quantum limit" and the 2021 John F. Keithley Award for Advances in Measurement Science. Siddiqi is a fellow of the American Physical Society and a recipient of the UC Berkeley Distinguished Teaching Award in 2016, the institution's highest honor for teaching and commitment to pedagogy.

Talk Title: RF Integrated Systems: Antenna-to-Computation
Series: Integrated Systems
Abstract: For decades, expanding wireless capacity has been driven by advances in RF IC technology towards the most efficient use of electromagnetic spectrum. Smaller, faster silicon devices have enabled the calibrations and DSP required for complex channel coding, pushing lower-frequency wireless systems close to the Shannon limit of capacity. The advent of SiGe BiCMOS and fine line RF CMOS has extended RF signal processing to 100 GHz and beyond, expanding the usable electromagnetic spectrum and wireless data capacity. Advanced materials have given rise to single-function superstar LNA's, switches and PA's to efficiently interface with the antenna, the highest performing now well beyond 100 GHz. Today with 5G beamforming, communication system technologies have borrowed from and converged with mature radar
technologies, and the wireless connectivity universe is expanding even more rapidly. But this expansion of the data capacity in the airwaves has pushed us up against the bottleneck of processing and off-loading data in the wired world. To take full advantage of the potential of these RF IC technologies, next-generation integrated systems must adopt a more holistic approach to optimize not just the entire signal chain, but the entire data chain. A system that was once defined from the antenna to bits and back again, must now be defined from antenna to computation and back again, including the algorithms and software required to drive complex RF SoCs. This talk will look at the evolution of the RF ICs that comprise a typical communication system, their connectivity to each other, their intersection with the RF transceivers of today, and the future challenges and opportunities awaiting the next generation of integrated system designers.

Talk Title: Two Fundamental Relations for Turbulent Flows
Abstract: wo fundamental effects of turbulence are (a) an increased rate at which kinetic energy is dissipated into heat and (b) an enhanced momentum (and heat) flux across boundary layers leading to much higher skin friction drag forces (and surface heat transfer). This presentation will introduce and apply two exact relations related to these fundamental effects, respectively. First, the concept of Stokes Flow Regularization (SFR) provides an exact expression for the scale-wise energy cascade rate in terms of vortex stretching and strain-rate self-amplification. Applied to data from fully-resolved simulations, this precisely quantifies the mechanisms responsible for generating large dissipation rates at small scales. SFR also serves as an intriguing alternative to spatial filtering as the basis of large-eddy simulation modeling. Specific potential modeling advantages will be discussed. Second, the Angular Momentum Integral (AMI) equation for turbulent boundary layers will be introduced. The AMI equation quantifies the impact of various flow phenomena throughout a boundary layer flow on the skin friction relative to a baseline laminar flow. An analogous integral equation for the surface heat transfer will also be introduced. Together, these provide a powerful method for probing flow data in terms of key engineering quantities of interest. Example applications for AMI-based analysis will be shown for boundary layer transition and supersonic turbulent boundary layers.
Biography: Perry Johnson Perry Johnson earned his Ph.D. in 2017 from Johns Hopkins University (advisor: Charles Meneveau), where his work on velocity gradient dynamics in turbulence won the Corrsin-Kovasznay award. He was then a postdoctoral fellow at the Center for Turbulence Research at Stanford University for three years, working on various topics related to small-scale turbulence, multiphase & particle-laden flows, and boundary layers. He joined the Mechanical and Aerospace Engineering department at the University of California, Irvine in 2020 as an assistant professor. His recent research on the energy cascade was featured in Physics Today, and his forthcoming review of multi-scale velocity gradient dynamics will appear in the next issue of Annual Review of Fluid Mechanics.

Speaker: Dominique Duncan, PhD., Assistant Professor of Neurology, BME and USC Stevens Neuroimaging and Informatics
Talk Title: Large-scale data archives and analytic tools for neurological disorders
Abstract: The Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx) is a multi-site, international collaboration including a parallel study of humans and an animal model, collecting MRI, EEG, and blood samples. The development of epilepsy after traumatic brain injury (TBI) is a multifactorial process and crosses multiple modalities. Without a full understanding of the underlying biological effects, there are currently no cures for epilepsy. This study aims to address both issues, calling upon data generated and collected at sites spread worldwide among different laboratories, clinical sites, in different formats, and across multicenter preclinical trials. Before these data can even be analyzed, a central platform is needed to standardize these data and provide tools for searching, viewing, annotating, and analyzing them. We have built a centralized data archive that will allow the broader research community to access these shared data in addition to analytic tools to identify and validate biomarkers of epileptogenesis in imaging and electrophysiology as well as in molecular, serological, and tissue data. Besides EpiBioS4Rx, we have also developed other large-scale multimodal data archives, including the Data Archive for the BRAIN Initiative (DABI) and the COVID-19 Data Archive (COVID-ARC) to encourage collaboration and expedite research in these areas.
Biography: Dominique Duncan is an assistant professor of Neurology, Neuroscience, and Biomedical Engineering at the USC Stevens Neuroimaging and Informatics Institute in the Laboratory of Neuro Imaging (LONI) at the University of Southern California.

Talk Title: Redefining Scalable Arrays using Bandwidth, Aperture, and Temperature for Next-Generation Wireless Networks
Series: Integrated Systems
Abstract: Emerging millimeter-wave and sub-THz communications promises to address the bandwidth limitations faced at sub-6GHz bands. Communications at this higher frequency however requires multiple antennas to compensate for propagation loss resulting in pointed beams. Conditional on the link being established, these beams provide wide bandwidths. However, these links can be short-lived for users with high mobility necessitating energy-efficiency and low-latency direction-finding approaches. These challenges necessitate rethink of multi-antenna radio front-ends for them to not only synergistically work with the digital signal processor but also satisfy new features meeting the energy- and spectral-efficiencies.
This talk will present recent research in true-time-delay based spatial signal processors to enable fast direction finding as well as wideband data communications for mobile communication applicable to sub-6GHz and millimeter-wave frequencies. Leveraging nanoseconds of delay ranges with picosecond resolutions, we describe true-time-delay based phased arrays capable of handling wide fractional bandwidths and enabling fast link discovery while maximizing the spectral- and energy-efficiencies. Pursuant to this, we will elaborate on interference-mitigation techniques in congested and contested networks that are critical for high energy- and spectral efficiencies. We will conclude this talk highlighting ongoing research on optimization of joint communications and wideband sensing, and temperature-scalable arrays that can potentially transform emerging wireless and space communications harnessing conjoined operations at room- and ultra-low-temperatures.

ECE Seminar: Verifiable Control of Learning-Enabled Autonomous Systems
Tue, Sep 26, 2023 @ 12:00 PM - 01:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Lars Lindemann, Assistant Professor, USC Thomas Lord Department of Computer Science
Talk Title: Verifiable Control of Learning-Enabled Autonomous Systems
Abstract: Autonomous systems research shows great promise to enable many future technologies such as autonomous driving, intelligent transportation, and robotics. Accelerated by the computational advances in machine learning and AI, there has been tremendous success in the development of learning-enabled autonomous systems over the past years. At the same time, however, new fundamental questions arise regarding the safety and reliability of these increasingly complex systems that operate in dynamic and unknown environments. In this talk, I will provide new insights and discuss exciting opportunities to address these challenges.
In the first part of the talk, we focus on reasoning about uncertainty of learning-enabled components in an autonomy stack. Existing model-based techniques are usually too conservative or do not scale. I will instead advocate for conformal prediction as an accurate and computationally lightweight alternative. We will first use conformal prediction to design predictive runtime verification algorithms that quantify uncertainty of learning-enabled systems. These algorithms can effectively compute the probability of a task violation during the execution of the system. I will then show how to design probabilistically safe motion planning algorithms in dynamic environments using such uncertainty quantification. While existing data-driven approaches quantify uncertainty heuristically, we quantify uncertainty in a distribution-free manner. Using ideas from adaptive conformal prediction, we can even deal with distribution shifts, i.e., when test and training distributions are different. We illustrate the method on a self-driving car and a drone that avoids a flying frisbee. In the second part of the talk, I present an optimization framework to learn safe control laws from expert demonstrations. In most safety-critical systems, expert demonstrations in the form of system trajectories that showcase safe system behavior are readily available or can easily be collected. I will propose a constrained optimization problem with constraints on the expert demonstrations and the system model to learn control barrier functions for safe control. Formal guarantees are provided in terms of the density of the data and the smoothness of the system model. We then discuss how we can account for model uncertainty and hybrid system models, and how we can learn safe control laws from high-dimensional sensor data. Two case studies on a self-driving car and a bipedal robot illustrate the method.

Speaker: Sam Tawfick, University of Illinois Urbana-Champaign
Talk Title: Nonlinear Mechanics and Robotic Mechanisms using Coiled Muscles and Snapping Beams
Abstract: My group is developing a roadmap for elastic actuating materials to replace bulky electric motors in miniature robots requiring large mechanical work output.
First, I will describe the mechanics of coiled muscles made by twisting nylon fishing lines, and how these actuators use internal strain energy to achieve a record breaking performance. Then I will describe intriguing hierarchical super, and hyper coiled artificial muscles which exploit the interplay between nonlinear mechanics and material microstructure. Next, I will describe their use to actuate the dynamic snapping of insect-scale jumping robots. The combination of strong but slow muscles with a fast-snapping beam gives rise to dynamic buckling cascade phenomena leading to effective robotic jumping mechanisms.
These examples shed light on the future of automation propelled by new bioinspired materials, nonlinear mechanics, and unusual manufacturing processes.

Talk Title: Advances in control and error correction of GKP codes in superconducting circuits
Series: Quantum Science & Technology Seminar Series
Abstract: The past four years have seen rapid experimental progress in realizing the quantum error correction code proposed in 2001 by Gottesman, Kitaev, and Preskill (GKP) in which logical states are encoded as oscillator grid states [1]. Recent milestones include code preparation and real-time error correction in trapped-ion motional modes and in superconducting cavities [2-6]. In this overview talk, I will review experiments from our lab at Yale that have led to these advances, focusing on the engineering of an experimental architecture for the code's realization in superconducting circuits [2]. I also will demonstrate how the same tools can be used for universal control of an oscillator with weak dispersive coupling to a qubit [5]. Finally, I will share our recent results on optimizing the error correction protocol using model-free reinforcement learning, leading to the demonstration of a fully error-corrected quantum memory with coherence beyond break even [6].
