SUMMARY:ESE Seminar: "The Role of Explicit Regularization in Overparameterized Neural Networks"
DESCRIPTION:Overparameterized neural networks have proved to be remarkably successful in many complex tasks such as image classification and deep reinforcement learning. In this talk\, we will consider the role of explicit regularization in training overparameterized neural networks. Specifically\, we consider ReLU networks and show that the landscape of commonly used regularized loss functions have the property that every local minimum has good memorization and regularization performance. Joint work with Shiyu Liang and Ruoyu Sun.

SUMMARY:ESE Seminar: "Learning is Pruning"
DESCRIPTION:The strong lottery ticket hypothesis (LTH) postulates that any neural network can be approximated by simply pruning a sufficiently larger network of random weights. Recent work establishes that the strong LTH is true if the random network to be pruned is a large poly-factor wider than the target one. This polynomial over-parameterization is at odds with experimental research that achieves good approximation by pruning networks that are only a small factor wider than the target one. In this talk\, I will tell you how we close this gap and offer an exponential improvement to the over-parameterization requirement. I will give a sketch of the proof that any target network can be approximated by pruning a random one that is only a logarithmic factor wider. This is possible by establishing a connection between pruning random ReLU networks and random instances of the weakly NP-hard SubsetSum problem. Our work indicates the existence of a universal striking phenomenon: neural network training is equivalent to pruning slightly overparameterized networks of random weights. I will conclude with sharing hints of a general framework indicating the existence of good pruned networks for a variety of activation functions\, architectures\, even applicable for the case where both initialization weights and activations are binary.

SUMMARY:MEAM Ph.D. Thesis Defense: "Structural and Mechanical Responses to Intermittent Parathyroid Hormone Treatment\, Discontinuation\, and Cyclic Administration Regimens"
DESCRIPTION:Bone mineral density rapidly decreases upon withdrawal from intermittent parathyroid hormone (PTH) treatment despite its potent effect of promoting bone formation. To better understand this adverse phenomenon\, this study first aimed to investigate the phenotype of PTH withdrawal in both intact and estrogen-deficient rat model by using a well-designed experiment combined with innovative longitudinal imaging techniques and localized cellular activities. Due to observing a continuous anabolic window upon early discontinuation of PTH treatment in estrogen-deficient animals\, we propose a potential effective treatment strategy\, the short cycles of PTH and antiresorptive treatment regimen\, which could extend the anabolic windows by increasing the number of newly activated modeling-based bone formation (MBF) sites. Lastly\, to understand the structure-function relationships of bone tissue formed through MBF compared to the remodeling-based bone formation (RBF)\, we developed an innovative imaging platform with a mechanical testing platform to determine the mechanical properties of MBF and RBF and their long-term contributions in intact animals.

SUMMARY:CBE PhD Dissertation Defense  | Investigation of High-Surface-Area Titanate (ATiO3) Thin Films Prepared by Atomic Layer Deposition
DESCRIPTION:Abstract: \n“Heterogeneous catalysis is critically important in the chemical-processing and energy-related industries. Ideally\, reaction sites on heterogeneous catalysts can be regenerated\, and the catalysts should be active throughout the catalytic process. However\, harsh reaction conditions and parallel side reactions can be harmful to the metal catalysts\, making deactivation a common phenomenon. Finding a catalyst that is stable can be a challenging yet significant task. Metal-doped perovskite materials have been referred to as “intelligent catalysts” because of the ability to insert and remove precious metal cations from the support lattice under cyclic redox conditions. The concept of “intelligent catalysts” became interesting because the stability of the doped metals was found to be significantly improved. However\, the concept was not entirely successful due to the low specific surface areas of these materials\, the slow kinetics for ingress and egress from the lattice\, and poor metal utilization. Reducing the length scale of the perovskite materials could potentially overcome these problems\, and it can be achieved by coating a thin perovskite film with a thickness of around 1nm on a high-surface-area onto an inert support. Work in this thesis used Atomic Layer Deposition (ALD) to deposit titanates (ATiO3\, A=Ca\, Sr or Ba) that were roughly 1-nm thick onto high-surface-area substrates. When using these thin-film materials as supports for catalytically active metals\, the thin-film samples showed properties similar to their bulk counterparts. Improved stabilities were found on the systems where strong interactions occur. However\, the interactions between metals and the thin-film perovskite materials to be different from bulk “intelligent catalysts” in some ways. The differences between bulk and thin-film systems can lead to very different particle geometries and catalytic properties. Systematic comparisons of metal-perovskite interactions were performed for the titanate thin films with different A-site cations. Changing A-site cations can lead to changes in metal properties\, including but not limited to the metal geometries\, reducibilities\, and the resulting catalytic performances. The role of A-site cations in determining the forms and degrees of metal-perovskite interactions were also discussed.“

SUMMARY:CBE PhD Dissertation Defense | Study of Metal Catalysts Supported on Thin Films of Perovskites prepared by Atomic Layer Deposition (ALD)
DESCRIPTION:Abstract: \n\nSintering is a severe problem with supported-metal catalysts in high-temperature applications\, such as in automotive-emissions control\, because it leads to a loss of catalytically active surface area. To stabilize the metal particles\, in 2001\, the Daihatsu group proposed using perovskite-supported metals\, which they referred to as “intelligent” catalysts. The original goal was to regenerate sintered metals by driving the metal into the oxide lattice by high-temperature oxidation and releasing the metal as small particles by reduction. Unfortunately\, the concept has not been entirely successful\, partially because of the large crystallite size and low surface areas of typical perovskites. To achieve higher surface areas and reduce the length scale for any ingress-egress of metal particles\, Atomic Layer Deposition (ALD) was used in this thesis to prepare thermally stable thin films of perovskites on high-surface-area supports. Metal catalysts\, Pt\, Ni\, Pd\, and Rh\, were deposited onto the perovskite thin films\, LaCoO 3 and LaFeO 3 \, using ALD.\n\n\n\n\n\nThis thesis focused on studying metal-perovskite interactions in the ALD samples of metals supported on LaFeO 3 films. It was found that metal-perovskite interactions could dramatically affect the preferential alignment of metal particles with the substrate\, the metal dispersions\, and catalytic activity. In the presence of the perovskite films\, the equilibrium oxidation of the metals could also shift several order-of-magnitudes towards lower PO 2 . The changes in the thermodynamic properties would further cause different catalytic behaviors. Systems of different metals supported on LaFeO 3 films were studied and compared; it was found that the metal-perovskite interaction is specific for each system.

SUMMARY:MSE Seminar: "The light stuff: sculpting photons at the molecular-scale for sustainability"
DESCRIPTION:We present methods to sculpt light at the atomic and molecular scale to detect and control chemical transformations\, en-route to improved planetary and personal health. First\, we study plasmon-driven chemical transformations\, focussing on the photocatalytic dehydrogenation of AuPd systems. Here\, the Au acts as a plasmonic light absorber and Pd serves as the catalyst. Using optically-coupled electron microscopy\, we find that plasmons modify the rate of distinct reaction steps differently\, increasing the overall rate more than ten-fold. Plasmons also open a new reaction pathway that is not observed without illumination\, laying a foundation for site-selective and product-specific photocatalysts. Next\, we describe methods to enable enantiospecific photochemistry\, using resonant dielectric nanoparticles. By overlapping electric and magnetic resonances\, these nanostructures can significantly enhance circular dichroism for improved chiral sensing and spectroscopy as well as high-yield enantioselective photochemistry. Finally\, we describe resonant nanophotonic surfaces that enable multiplexed detection of SARS-CoV-2 gene sequences. The high quality factor (high-Q) produces a large amplification of the electromagnetic field intensities near the nanostructures that increase the response to minute refractive index changes from targeted binding of nucleic acids; simultaneously\, the optical signal is beam-steered for multiplexed detection. We will present the design and development of this quantitative optical assay\, as well as application to clinical samples.

SUMMARY:CIS Seminar: “Hash Tables Lecture”
DESCRIPTION:Abstract: \nThe lecture that I will cover is going to be on Hash Tables. The lecture is designed for an introductory CS course and/or a data structures course. We are in the last 3rd of the semester when this topic is covered. At this point\, students are comfortable with programming (in Python). In addition\, they have some experience with complexity analysis in the context of the topics we have already covered in the course\, including iteration\, recursion\, various search and sort algorithms\, arrays\, and lists. \nThe lecture will discuss what hash tables are\, their importance\, and examples of their use in real life. We will then talk about what hashing is and how hash tables work. We will briefly discuss collisions\, what they are\, how to deal with them\, and why they are problematic. Lastly\, we will introduce dictionaries\, the hash table implementation in Python. The lecture will involve multiple active learning exercises and live coding.

SUMMARY:BE Seminar: Deconstructing and Reconstructing Human Tissues (Kelly Stevens)
DESCRIPTION:This seminar will be held virtually on Zoom. Check email for details or contact ksas@seas.upenn.edu. \nAlthough much progress has been made in building artificial human tissues over the past several decades\, replicating complex tissue structure remains an enormous challenge. To overcome this challenge\, our field first needs to create better three-dimensional spatial maps\, or “blueprints” of human tissues and organs. We also need to then understand how these spatial blueprints encode positional processes in tissues. My group is developing new advanced biofabrication technologies to address both of these issues. Here\, I will describe some of our work in both attaining transcriptomic maps as well as in controlling spatiogenetic wiring of human artificial tissues.

SUMMARY:PICS Colloquium: "Machine learning for Fluid Mechanics"
DESCRIPTION:Abstract: Many tasks in fluid mechanics\, such as design optimization and control\, are challenging because fluids are nonlinear and exhibit a large range of scales in both space and time. This range of scales necessitates exceedingly high-dimensional measurements and computational discretization to resolve all relevant features\, resulting in vast data sets and time-intensive computations. Indeed\, fluid dynamics is one of the original big data fields\, and many high-performance computing architectures\, experimental measurement techniques\, and advanced data processing and visualization algorithms were driven by decades of research in fluid mechanics. Machine learning constitutes a growing set of powerful techniques to extract patterns and build models from this data\, complementing the existing theoretical\, numerical\, and experimental efforts in fluid mechanics. In this talk\, we will explore current goals and opportunities for machine learning in fluid mechanics\, and we will highlight a number of recent technical advances. Because fluid dynamics is central to transportation\, health\, and defense systems\, we will emphasize the importance of machine learning solutions that are interpretable\, explainable\, generalizable\, and that respect known physics.

SUMMARY:MEAM Seminar: "Wave Engineering: From Geometry to Fragility"
DESCRIPTION:The elastic properties of materials are determined by a few material constants such as the Young’s modulus. Using super-structures one can effectively change these “constants”. In this way we obtain functionalities such as wave-guiding\, acoustic lensing or programmable failure. I will show how topological band theory\, known from the description of electrons in solids\, provides us with a powerful design-principle for such mechanical metamaterials. Moreover\, mechanical metamaterials offer a powerful platform for the study of fundamentally new phenomena that are hard to observe in other arenas. Here\, I will highlight the first measurement of a quadrupole topological insulator in a silicon based metamaterial\, the implementation of an axial gauge field in an acoustic Weyl system and the measurements of fragile topology.

SUMMARY:CBE Seminar: "Phase Behavior and Self-Assembly of Active Colloids"
DESCRIPTION:Abstract \nIn recent years\, a new type of synthetic microparticle has captured the imagination of researchers across the physical and biological sciences. These so-called active colloids convert chemical or environmental free energy into irreversible directed motion. Impressively\, the active force generated by the particles can lead to self-propelling speeds of tens of hundreds of microns per second. Active colloids challenge our theoretical understanding of nonequilibrium phenomena and simultaneously represent a potentially innovative approach to directed transport and material design at the microscale. In this talk\, I will discuss one of the most striking features of active colloids\, which is their rich and complex nonequilibrium phase behavior. Special emphasis will be given to motility-induced phase separation where purely repulsive active colloids undergo a liquid-gas phase transition. This talk will provide a quantitative understanding of this phenomenon by generalizing concepts in classical statistical mechanics and liquid state theory to active systems. This newfound understanding can be leveraged to improve the self-assembly of many complex colloidal structures using active colloids.

SUMMARY:BE Seminar: "Designing Biology for Detection and Control" (Pamela A. Silver)
DESCRIPTION:This seminar will be held virtually – Zoom link coming soon. \nThe engineering of Biology presents infinite opportunities for therapeutic design\, diagnosis\, and prevention of disease.  We use what we know from Nature to engineer systems with predictable behaviors.  We also seek to discover new natural strategies to then re-engineer.  I will present concepts and experiments that address how we approach these problems in a systematic way.  Conceptually\, we seek to both design cells and proteins to control disease states and to detect and predict the severity of emerging pathogens.  For example\, we have engineered components of the gut microbiome to act therapeutics for infectious disease\, proteins to prolong cell states\, living pathogen sensors and high throughput analysis to predict immune response of emerging viruses.

SUMMARY:GRASP On Robotics: "Wearable Haptic Devices for Ubiquitous Communication"
DESCRIPTION:Abstract: Haptic devices allow touch-based information transfer between humans and intelligent systems\, enabling communication in a salient but private manner that frees other sensory channels. For such devices to become ubiquitous\, their physical and computational aspects must be intuitive and unobtrusive. The amount of information that can be transmitted through touch is limited in large part by the location\, distribution\, and sensitivity of human mechanoreceptors. Not surprisingly\, many haptic devices are designed to be held or worn at the highly sensitive fingertips\, yet stimulation using a device attached to the fingertips precludes natural use of the hands. Thus\, we explore the design of a wide array of haptic feedback mechanisms\, ranging from devices that can be actively touched by the fingertips to multi-modal haptic actuation mounted on the arm. We demonstrate how these devices are effective in virtual reality\, human-machine communication\, and human-human communication. \nZoom Webinar Link: https://upenn.zoom.us/j/94052429739

SUMMARY:MEAM Seminar: "Modeling the Behavior of Shape Memory Alloy Structures"
DESCRIPTION:I will present recent work on the modeling of the structural response of shape memory alloy tubes\, bars\, and beams. We have developed a new constitutive model that captures pseudoelastic transformation induced recoverable deformation in SMAs including the strong asymmetries in the tensile and compressive responses. Instead of introducing multiple conditions for forward phase transformation\, reverse phase transformation\, and martensite reorientation\, the model is based on a J2-type nonlinear kinematic hardening framework with a single transformation surface and the back stress represented through a weighted mix of two potential functions that are calibrated to the tensile and compressive stress-strain responses of the material. The constitutive model has been used to simulate numerically the interaction of these complex material behaviors with structural nonlinear behavior observed in experiments. Problems analyzed include the buckling and recovery of NiTi tubes under axial compression\, the propagation of a well defined deformation front in uniaxial tension\, and the reversible propagation of curvature localization in NiTi tubes under bending. The numerical simulations reproduce the structural behavior both qualitatively and quantitatively demonstrating the fidelity of the constitutive modeling framework developed. After illustrating the success of the isothermal model\, I will present some recent work on modeling non-isothermal behavior within the same constitutive framework.
