SUMMARY:MEAM Seminar: "Predicting and Reducing High-Speed Jet Noise"
DESCRIPTION:The intense noise radiated by supersonic jets leads to sound-induced structural vibration\, fatigue and personnel-related operational difficulties. Experimental\, theoretical\, and computational investigations into the physics and control of jet noise have identified several important sound sources\, including wavepackets\, screech\, Mach wave radiation\, and broadband shock associated noise. Reducing the loudest sources of jet noise\, without sacrificing propulsive performance\, has relied on intuition\, parametric survey\, or optimal control techniques. With the aim of developing a more general and robust method of jet noise reduction\, we present a physics-based approach that reveals jet dynamics/mechanisms\, highlighted by a linear resolvent analysis\, crucial to the the generation of jet noise in a biconical tactical jet nozzle. Our approach uses large-eddy simulation to predict the turbulent flow within and exhausted by the jet nozzle and then identifies optimal forcing/response modes of the compressible Navier-Stokes operator\, linearized about a fully-resolved jet mean flow\, to identify and manipulate coherent structures that are primarily responsible for the production of jet noise. The operating conditions of the jet and nozzle geometry are motivated by tactical Naval aircraft.

SUMMARY:CIS Seminar: "The Long Arm of Theoretical Computer Science: A Case Study in Blockchains/Web3"
DESCRIPTION:Blockchains that support a general contract layer (e.g.\, Ethereum) export the functionality of a general-purpose\, ownerless\, and open-access computer that can enforce property rights for digital data.  How is such functionality implemented?  Using a lot of extremely cool computer science ideas! And like everywhere else in computer science\, theory plays an undeniable role in the understanding and advancement of this technology.  In this talk\, Tim Roughgarden will highlight three examples (among many): \n\nPossibility and impossibility results for permissionless consensus (i.e.\, implementing an “ownerless” computer).\nIncentive-compatible transaction fee mechanism design (part of implementing an “open-access” computer).\nSuccinct proofs of computation (for boosting the computer’s power by piggybacking on off-chain computation).\n\nParts of this talk are based on joint work with Andrew Lewis-Pye.

SUMMARY:ASSET Seminar: How to Design Molecules that Dock Well but Can't Exist\, Jacob Gardner\, Ph.D.
DESCRIPTION:ABSTRACT:BIO \nMachine learning has become an indispensable aid to researchers developing the next generation of novel therapeutics. In this talk\, I will discuss how some of the most important problems  in virtual screening for new potential drug molecules can be cast as black-box optimization problems\, where the goal is to find molecules maximizing some desired property — for example\, the binding affinity to a known drug target. By leveraging recent work on representation learning for molecules and high dimensional black-box optimization\, we are able to achieve up to a 20x performance improvement over state of the art on several of the most widely used benchmarks for molecule design. I will then show how this powerful new approach reveals flaws in tools commonly used for computational molecule design. Even the most widely used docking simulators can be fooled by a sufficiently powerful optimizer producing molecules that could not plausibly exist in nature — a challenge reminiscent of adversarial image generation in computer vision. These findings can be mitigated to a degree through the use of constrained optimization\, but also motivate adapting lessons from robust machine learning to the docking simulators themselves.

SUMMARY:Fall 2022 GRASP SFI: Charlie Andersen and Terry Scott\, Burro\, "Founders' journey of building a robotics company in Philadelphia"
DESCRIPTION:This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. \nABSTRACT\nCharlie Andersen (CEO) and Terry Scott (CTO) are two of the founders of Burro. They share their origin story of Burro and we follow their journey of building a robotics company and a product intended to bring new life into an ancient industry. Off a small launchpad of accelerator funding and Charlie’s personal savings\, they build their proof of concept utility robot and target specific sectors within agriculture to garner interest and investment. With the closure of a seed round\, they embarked on turning that proof-of-concept into a functional prototype. They will share how the company\, product and technology has evolved from 4 people and an idea to a company with 33 members and growing\, with one of the largest deployed operational robotic fleets within agricultural robotics.

SUMMARY:MSE Seminar: “A More Sustainable Future via Polymer Circularity"
DESCRIPTION:In a Circular Economy\, atoms and molecules are kept inside the economy where they continue to produce value\, and they are kept out of unwanted places like our environment.  At a high level\, this concept applied to polymers and plastics should reduce the flow of material into the environment\, while improving efficiency and reducing demand for natural resources\, but the reality is much more complex.  When considering the full supply chain\, from design and manufacture\, to use and retrieval\, the system is full of challenges and potential for leakage.  The only way to ensure progress\, is to design changes to the system with these fundamental goals in mind\, and to build the measurement and data frameworks that can support difficult decision-making and confidence in the results.  The talk will present some NIST activities in fundamental materials design and measurement relevant to this larger need\, including polyolefin molecular design for improved recovery\, and models and processes to improve compatibilization of polymer blends relevant to mechanical recycling.

SUMMARY:Fall 2022 GRASP on Robotics: Daniel Hashimoto\, University of Pennsylvania\, "Building Multidisciplinary Teams for Surgical Translation of Artificial Intelligence"
DESCRIPTION:This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. \nABSTRACT\n\nSurgical Data Science aims to improve the quality of interventional healthcare and its value through capture\, organization\, analysis and modelling of data. The operating room has long been siloed from in-depth review and analysis\, but recent advances in computer vision and surgical robotics offer the promise of improved understanding of intraoperative events. However\, challenges remain around collecting and annotating intraoperative data and modeling complex physiological phenomena and workflow during surgery. We will explore a few of these issues and discuss the role of multidisciplinary teams in promoting the democratization of surgical knowledge through surgical data science.

SUMMARY:MEAM Seminar: "Mechanical Behavior of Self-healing Hydrogels with Chemical and Physical Cross-links: Theory and Experiments"
DESCRIPTION:In recent years polymer chemists have made tremendous strides in the synthesis of biocompatible\, tough\, self-healing hydrogels. However\, there are not many comprehensive mechanical models that capture the observed time dependent mechanical behavior of these gels (especially fracture) to the underlying\, rate dependent bond breaking and reformation processes. In this talk I will summarize some of the progress we have made on two systems; the first is a Poly(vinylalcohol) (PVA) hydrogel chemically crosslinked by glutaraldehyde and physically crosslinked by Borax ions. The second is a chemically crosslinked Polyampholyte gel (c-PA) synthesized by random copolymerization of cationic and anionic monomers at a high concentration around the charge balanced point. We formulated a 3D\, large deformation viscoelastic constitutive model based on breaking and healing kinetics of physical cross-links. We demonstrate this model accurately captures the rate dependent behavior of these gels under complex loading histories. We studied the asymptotic structure of the crack tip fields. We develop a finite element model to numerically study the stress and deformation fields near the tip of a stationary crack in single edge cracked specimens. The theoretical and finite element results (3D and 2D plane stress) agree remarkably well with experimentally observed crack opening profiles in the PVA gel system. The model parameters are extracted from experiments using a newly developed fitting method based on Meta-modeling and Neutral network. We carried out relaxation experiments on two different types of samples to study the nonlinear viscoelastic behavior of the c-PA system. A simple model is used to explain this behavior. Our modelling and experimental efforts can lead to better understanding of the complex load transfer process near the crack tip and time dependent delayed fracture of gels and elastomers.

SUMMARY:CIS Seminar: " Rich Babies\, Poor Robots: towards rich sensing\, continuous data and multiple environments"
DESCRIPTION:In recent years\, we have seen a shift in different fields of AI such as computer vision\, robotics. From task-driven supervised learning\, we are now starting to see shift towards more human like learning. Self-supervised learning\, embodied AI\, multimodal learning are few subfields which have emerged from this shift. Yet I will argue the shift is half-hearted in nature and there is a huge situational gap between babies (human learners) and current robots. Our babies learn continuously from multiple environment using five different senses using both active and passive data.  On the other hand\, our AI algorithms still primarily use vision (best case)\, learn from fixed datasets or pre-defined environments and use either passive or active data. In this talk\, I will argue how to bridge this gap. First\, I will talk about how to bring tactile sensing into mainstream. More specifically\, I will introduce our magnetic sensing skin called ReSkin. Next I will talk how our current setups lack the lifelong learning aspect. More specifically\, I will introduce our recent efforts in developing continuous versions of self-supervision and curiosity/exploration. Finally\, if time remains I will talk about how to use passive and active data together to learn actions.

SUMMARY:ASSET Seminar: Building certifiably safe and correct large-scale autonomy\, Chuchu Fan (Massachusetts Institute of Technology)
DESCRIPTION:ABSTRACT: \nThe introduction of machine learning (ML) and artificial intelligence (AI) creates unprecedented opportunities for achieving full autonomy. However\, learning-based methods in building autonomous systems can be extremely brittle in practice and are not designed to be verifiable. In this talk\, I will present several of our recent efforts that combine ML with formal methods and control theory to enable the design of provably dependable and safe autonomous systems. I will introduce our techniques to generate safety certificates and certified control for complex autonomous systems\, even when the systems have a large number of agents and follow nonlinear and nonholonomic dynamics.

SUMMARY:BE Seminar: "Precision Engineering for Cancer Immunotherapy" (James Moon\, University of Michigan)
DESCRIPTION:This is a hybrid seminar which will be held in Glandt Forum (Singh Center) and via Zoom (link coming soon). \nPrecision Engineering for Cancer Immunotherapy \nCancer immunotherapy is now considered the fourth pillar of cancer therapy\, joining the ranks of surgery\, radiotherapy\, and chemotherapy. However\, only a small subset of cancer patients responds to cancer immunotherapy. Thus\, new approaches are needed to amplify anti-tumor immunity\, to convert cold tumor into hot tumor\, and to potentiate immunotherapies with minimal immune-related adverse events. The gut microbiome has recently emerged as the next frontier in drug development; however\, it remains unclear how to effectively alter gut microbiota for treating various diseases\, including cancer. Here\, we present new biomaterial-based strategies for altering the gut microbiome and improving the safety and efficacy of cancer immunotherapy. We are developing new dietary fiber-based biomaterials for in situ modulation of the gut microbiome for augmenting local and systemic immune responses. We will present the therapeutic potential of our gut modulation approach in the context of improving the efficacy of immune checkpoint blockers while mitigating immune-related adverse events. In our second research thrust\, we are developing a new nanoparticle platform for systemic delivery of STING (stimulator of IFN genes) agonists. While local STING activation can convert cold tumor into hot tumor\, it has been challenging to develop STING agonists that can treat disseminated cancer due to their toxicity. Here\, we will present our next-generation STING agonists that allow for systemic cancer therapy with potent efficacy\, favorable pharmaceutical properties\, and acceptable safety profiles in various murine and rabbit tumor models. Our biomaterial-based strategies may offer powerful and convenient approaches to regulate the immune system as potential therapies for cancer and other diseases.

SUMMARY:Fall 2022 GRASP on Robotics: Wenzhen Yuan\, Carnegie Mellon University\, "Making sense of the physical world with high-resolution tactile sensing"
DESCRIPTION:This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. \n  \nABSTRACT\nIn this talk\, I will introduce the development of a high-resolution robotic tactile sensor GelSight\, and how it can help robots understand and interact with the physical world. GelSight is a vision-based tactile sensor that measures the geometry of the contact surface with a spatial resolution of around 25 micrometers\, and it also measures the shear forces and torques at the contact surface. With the help of high-resolution information\, a robot could easily detect the precise shape and texture of the object surfaces and therefore recognize them. But it can help robots get more information from contact\, such as understanding different physical properties of the objects and assisting with manipulation tasks. The talk will cover our work on using GelSight to detect slip during grasping and perceiving object properties such as hardness and viscosity of the liquid. I will also present our work in simulating the tactile sensor and using the simulated sensor input to boost the robot’s capability to perform perception and grasping tasks in reality. These simulation tools can also help us to rethink the sensor design challenge and how tactile sensors can be used for various types of robots.

SUMMARY:PICS Colloquium: "Group-Theoretic Approach for Nonlinear Problems in Mechanics with High Symmetry Avoids Use of Imperfections"
DESCRIPTION:Many interesting problems in nonlinear mechanics\, from classical to more recent\, pertain to applications with high initial symmetry: from the buckling of thin walled structures to the morphing in architected materials – the list is long! A common feature of these problems\, in addition to their importance for engineering applications\, is their great theoretical interest due to the complex bifurcation mechanisms leading to their failure. Unlike the classical Euler column buckling with the widely separated bifurcation points where the post-bifurcation equilibrium paths can be easily found using imperfections in the shape of the different eigenmodes\, using imperfections in these highly symmetric structures with complex bifurcation diagrams is confusing and can often lead to erroneous results. \nThe method proposed here is based on the perfect structure and uses the properties of its initial symmetry group to identify and follow the bifurcated equilibrium paths: primary\, secondary\, tertiary and so on\, and for the case of elastic systems\, to study their stability. Three different applications will be presented here: the development of folds and creases in an axially compressed elastic half-space\, the pattern formation in biaxially compressed circular honeycomb and the thermo-mechanical martensitic transformations in NiTi crystals. Time-permitting some additional applications in dissipative systems (step bunching and meandering instabilities homoepitaxial crystal growth) might be presented.

SUMMARY:ESE Fall Colloquium - "On the Principles of Parsimony and Self-Consistency: Structured Compressive Closed-Loop Transcription"
DESCRIPTION:Ten years into the revival of deep networks and artificial intelligence\, we propose a theoretical framework that sheds light on understanding deep networks within a bigger picture of intelligence in general. We introduce two fundamental principles\, Parsimony and Self-consistency\, that address two fundamental questions regarding Intelligence: what to learn and how to learn\, respectively. We argue that these two principles can be realized in entirely measurable and computable ways for an important family of structures and models\, known as a linear discriminative representation (LDR). The two principles naturally lead to an effective and efficient computational framework\, known as a compressive closed-loop transcription\, that unifies and explains the evolution of modern deep networks and modern practices of artificial intelligence. Within this framework\, we will see how fundamental ideas in information theory\, control theory\, game theory\, sparse coding\, and optimization are closely integrated in such a closed-loop system\, all as necessary ingredients to learn autonomously and correctly. We demonstrate the power of this framework for learning discriminative\, generative\, and autoencoding models for large-scale real-world visual data\, with entirely white-box deep networks\, under all settings (supervised\, incremental\, and unsupervised). We believe that these two principles are the cornerstones for the emergence of intelligence\, artificial or natural\, and the compressive closed-loop transcription is a universal learning engine that serves as the basic learning units for all autonomous intelligent systems\, including the brain. \nRelated papers can be found at: https://arxiv.org/abs/2207.04630 and https://www.mdpi.com/1099-4300/24/4/456/htm

SUMMARY:Tedori-Callinan Lecture: "Mixing of Granular Materials\, Inertial Suspensions\, and Cement"
DESCRIPTION:Flows of particulate materials are ubiquitous in nature and industry. Predictions of flow rates and mixing times rely on an understanding of the rheological properties of the materials\, which can differ considerably from that associated with a single-phase fluid. This presentation highlights some unique features of granular materials and inertial suspensions and includes recent experimental results. In addition\, the seminar overviews new work related to the mixing and gaseous diffusion in cement. Cement production releases significant amount of carbon dioxide; carbon dioxide can be partially reabsorbed into cement by diffusion through the multiphase material. The ongoing research includes modeling of the carbon dioxide uptake and considers ways to accelerate the process\, such as mixing with the cement paste.

SUMMARY:ESE Ph.D. Thesis Defense: "Design of Low-power CMOS Integrated Systems: from Biomedical Applications to Optical Links"
DESCRIPTION:Electronic and photonic microsystems realized in the form of integrated circuits (IC) has been revolutionizing numerous fields that traditionally exploit bulky implementations. The advantages stemming from device miniaturization have opened up wide and growing opportunities to design for unprecedented functionality and enhanced performance. Leveraging novel CMOS and silicon photonic IC designs\, this thesis presents four energy-efficient systems focusing on sensing and communication techniques: first\, a somatosensory feedback system\, composed of wireless body channel transceivers and implantable sensor nodes\, is proposed to restore a sense of touch to a paralyzed hand; second\, an analog SoC is implemented for neural signal recording and processing\, achieving accurate and unsupervised classification of action potentials; third\, a monolithically integrated\, power and area efficient PAM4 optical receiver is developed for a wavelength-division multiplexing (WDM) system achieving 1 Tb/s aggregate data-rate; finally\, an electronic-photonic lab-on-chip with optical power and data transmission is proposed to utilize the long-reach and low-cost fiber interconnects.

SUMMARY:ASSET Seminar: Decision-Aware Learning for Global Health Supply Chains\, Osbert Bastani (University of Pennsylvania)
DESCRIPTION:ABSTRACT: \nMachine learning algorithms are increasingly used in conjunction with optimization to guide decision making. A key challenge is aligning the machine learning loss with the decision-making loss. Existing solutions have limited flexibility and/or scale poorly to large datasets. We propose a principled decision-aware learning algorithm that uses a Taylor expansion of the optimal decision loss to derive the machine learning loss. Importantly\, our approach only requires a simple re-weighting of the training data\, allowing it to easily and scalably be incorporated into complex modern data science pipelines while producing sizable efficiency gains. We apply our framework to optimize the distribution of essential medicines in Sierra Leone in collaboration with their National Medical Supplies Agency. Out-of-sample results demonstrate that our end-to-end approach significantly reduces unmet demand across 1000+ health facilities throughout Sierra Leone.

SUMMARY:Fall 2022 GRASP SFI: Roberto Calandra\, Meta AI\, "Perceiving\, Understanding\, and Interacting through Touch"
DESCRIPTION:This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. \nABSTRACT\nTouch is a crucial sensor modality in both humans and robots. Recent advances in tactile sensing hardware have resulted — for the first time — in the availability of mass-produced\, high-resolution\, inexpensive\, and reliable tactile sensors. In this talk\, I will argue for the importance of creating a new computational field of “Touch processing” dedicated to the processing and understanding of touch\, similarly to what computer vision is for vision. This new field will present significant challenges both in terms of research and engineering. To start addressing some of these challenges\, I will introduce our open-source ecosystem dedicated to touch sensing research. Finally\, I will present some applications of touch in robotics and discuss other future applications.

SUMMARY:MSE Seminar: “Understanding Degradation in Metal Halide Perovskite Solar Cells and Modules”
DESCRIPTION:Halide perovskite solar cells (PSCs) have been the focus of much research in recent years due to their extremely high photoconversion efficiencies and their ability to be synthesized by solution processing.  These materials crystallize in the perovskite\, AMX3 crystal structure where A is a monovalent cation (e.g. methyl ammonium\, MA\, formamidinium\, FA\, and/or Cs)\, M is the metal cation and X is the halide anion. While great strides have been made to optimize the device performance of PSCs\, there remain open questions as to the long-term field performance of these materials. While constant improvement in lab scale performance stability is being demonstrated a fundamental understanding of degradation mechanisms can still provide key insight into performance improvements. In addition\, to fundamental lab scale studies field performance will be required to de-risk this technology for commercialization. In this talk\, I will cover examples of both lab scale and field studies to improve our understanding of PSCs degradation mechanisms. First\, I will discuss an application of X-ray scattering methods to probe the nanoscale heterogeneity of PSC absorber layers and couple these results to device level stability studies to understand the role heterogeneity plays in device performance. Finally\, I will present a brief overview of an initial field demonstration of PSC modules as part of the Perovskite PV Accelerator for Commercializing Technologies\, PACT\, program. Together this work aims to improve our confidence in real world PSC module performance.

SUMMARY:ESE Fall Colloquium - "Phase Transitions\, Symmetry\, and Reed-Muller Codes on BMS Channels"
DESCRIPTION:This talk will begin by discussing phase transitions in high-dimensional statistical inference problems. Some effort will be made to distinguish between problems with random structure (e.g.\, random codes and sparse PCA) and problems with deterministic structure (e.g.\, highly symmetric codes such as Reed-Muller codes). For problems with deterministic structure\, we will observe that symmetry can sometimes play a key role in characterizing their phase transitions. In particular\, I will describe my recent work with Galen Reeves that proves Reed-Muller (RM) codes achieve capacity on binary memoryless symmetric (BMS) channels with respect to bit-error rate. This result resolves a long-standing open problem that connects information theory and error-correcting codes. Our approach generalizes some elements of an earlier proof for the binary erasure channel but also derives new tools to avoid previous steps that do not generalize. The new idea is to combine a nesting property of RM codes with new information inequalities relating the derivative of the conditional entropy (as a function of the channel parameter) with minimum mean-squared error estimation.
