SUMMARY:BE Seminar: "Engineering the cell-matrix interface – understanding and guiding cell function" (Claudia Loebel\, University of Michigan)
DESCRIPTION:The native extracellular microenvironment dynamically remodels as cells synthesize\, assemble\, and remodel their surroundings during tissue development\, injury\, and repair. In my research group\, we use engineered systems to both probe mechanisms of cell-extracellular matrix (ECM) interactions (e.g.\, mechanobiology) and to guide cell function towards therapeutic behaviors (e.g.\, tissue repair/regeneration). In this seminar\, I will share our recent efforts to visualize and identify the composition of secreted ECM to better understand cellular responses and to design programmable soft materials that harness dynamic cell-ECM interactions.\nWe have used these systems to reproduce folding morphologies of epithelial tissues (e.g.\, airway constriction)\, and to manipulate secreted ECM components as means to better understand the evolution of matrix in organ development (using lung organoids) and repair (using ex vivo lung tissue). Our evolving understanding of matrix dynamics and turnover will not only open up new avenues for understanding biological mechanisms but will also allow us to design better materials systems for therapeutic interventions.

SUMMARY:ESE Fall Seminar - "Tools for designing some exciting chips"
DESCRIPTION:There is an enormous interest in developing customized\, domain-specific systems-on-a-chip.  Continued improvement in computing efficiency requires functional specialization of hardware designs. But designing complex chips is difficult.   This talk presents the Chipyard framework\, an integrated SoC design\, simulation\, and implementation environment for specialized compute systems. Chipyard includes configurable\, composable\, open-source\, generator-based IP blocks that can be used across multiple stages of the hardware development flow while maintaining design intent and integration consistency. We discuss some sample designs\, the use of the framework in classes\, and opportunities for extension and improvement.

SUMMARY:CBE Seminar: "Design of Solid-state Nanomaterials for Electrocatalysis: A Case Study of Oxygen Evolution Reaction Electrocatalysts" (Yang\, UIUC)
DESCRIPTION:High-level control of atomic and surface structures is a hallmark of the application of nanomaterials in a range of electrochemical and electrocatalytic devices\, such as water electrolyzer. They play critical roles in our effort to develop energy conversion and storage technologies that have net zero carbon impacts. Nanostructured metal oxides made for catalyzing the oxygen evolution reaction (OER) is one representative example. Unlike the traditional heterogeneous catalysis\, both bulk and surface properties are important in the design of active and durable electrocatalysts. This is because besides the adsorbate evolution mechanism (AEM)\, lattice oxygen mechanism (LOM) is often involved in the catalytic cycle. In this talk\, I will present our recent work on the synthesis-structure-electrocatalytic property relationship of complex oxides that can be described in a generic formula of AxByOz\, where A and B can be a single metal cation or mixed cations located at a given lattice site. We haveexamined several archetypes of oxide structures\, including perovskite\, pyrochlore\, spinel\, and Ruddlesden-Popper (RP) phasecompounds and their site-mixed solids\, all of which are found to be active for OER under either acid or base conditions. Ourresults indicate defect engineering in these solids is particularly important for OER catalysis. Thus\, it is essential\, besides agood understanding of heterogeneous catalysis\, one needs to take a solid state chemistry view in order to uncovering thecatalyst design for optimal performance. How to regulate the cation sites and oxygen defect chemistry for enhancing the bondand lattice stability of key structural constituents can be important. The new understandings should inform the approach tothe fabrication of earth-abundant oxide electrocatalysts for hydrogen production and utilization.

SUMMARY:LSRM Presents The Robert Maddin Lecture in Materials Science: "Active & Adaptive Matter Driving Cell Dynamics"
DESCRIPTION:Control of shape and movement is essential for cell physiology\, from cell migration to control of tissue shape. The mechanical behaviors of living cells are controlled by materials constructed by protein-based assemblies within the cell interior.  These soft materials both regulate how forces generated by individual mechanoenzymes are transmitted to cell and tissue scales as well as how mechanical properties evolve\, or adapt\, over time to allow for smooth transitions. I will describe my lab’s recent efforts to understand the design principles of the active\, soft materials that drive multi-cellular dynamics.  In particular\, I will describe our progress to reveal design principles by which the actin cytoskeleton senses\, generates\, and adapts to mechanical force.  Hopefully\, I will convince you that the materials within cells provide a rich playground to understand design principles of active and adaptive soft materials.

SUMMARY:MEAM Seminar: "Defending the Planet: The DART Mission\, and Mechanics Among the Asteroids"
DESCRIPTION:An on-orbit demonstration of asteroid deflection is a key test of our ability to defend the planet from an incoming asteroid. The recent DART (Double Asteroid Redirection Test) mission was NASA’s demonstration of kinetic impactor technology\, impacting an asteroid to adjust its speed and path. The DART spacecraft impacted the asteroid Dimorphos on September 26\, 2022\, and was the first-ever space mission to demonstrate asteroid deflection by a kinetic impactor. We discuss the mission\, and the critical role that mechanics plays in such planetary defense missions. \nMost asteroids are “small” rocky bodies (they can vary in size from sub-m to several hundred km). The structure and surface topography of asteroids are determined by impact and fracture processes that occur over an immense range of timescales. Recent observations have demonstrated that many small asteroids are “rubble-piles\,” collections of rocks held together by gravity. What determines this structure? We examine the disruption and breakdown of asteroids by studying the multiscale mechanics of dynamic fracture and fragmentation\, coupled with computational simulations of gravitational re-accumulation. The critical mechanisms are addressed through fundamental high-strain-rate experiments\, high-speed visualization\, theoretical and computational modeling of failure processes\, and computational simulations of asteroid damage and disruption. Our focus is on the relative roles of impact and thermal loading on the nature of near-Earth asteroids (NEAs) that may potentially impact the Earth.

SUMMARY:ESE Fall Seminar - "Large Observational Study of the Causal Effects of a Nudge and the Geometry of Causality"
DESCRIPTION:Nudges are interventions promoting healthy behavior without forbidding options or significant incentives. As an example of a nudge\, the Apple Watch encourages users to stand by delivering a notification if they have been sitting for the first 50 minutes of an hour. \nBased on 76 billion minutes of observational standing data from 160\,000 subjects in the public Apple Heart and Movement Study\, amount of data in the field that makes this work one of the largest ever in the subject\, we estimate the causal effect of this notification using a novel regression discontinuity design for time-series data with time-varying treatment. We show that the nudge increases the probability of standing by up to 44%\, a very significant effect compared to what has been reported in the literature\, remaining effective with time\, even after almost 2 years. The nudge’s effectiveness increases with age\, and it is independent of gender. Closing Apple Watch Activity Rings\, a visualization of participants’ daily progress in Move\, Exercise\, and Stand\, further increases the nudge’s impact. We conclude the presentation with some recent work on connections between geometry and causal inference. \nThe first part of the presentation is joint work with Achille Nazaret while the second is with Amir Farzam and Allen Tannenbaum.

SUMMARY:ESE PhD Thesis Defense: "Control of Multi-Contact Systems via Local Hybrid Models"
DESCRIPTION:For many important tasks such as manipulation and locomotion\, robots need to make and break contact with their environment. Although such multi-contact systems are common\, they pose a significant challenge when it comes to analysis and control. This thesis exploits the local hybrid structure of such problems and presents scalable and fast algorithmic solutions. First\, we present an MPC framework for multi-contact systems. The method is based on the alternating direction method of multipliers (ADMM) and is capable of high-speed reasoning over potential contact events. Then\, we focus on utilizing tactile measurements for reactive control\, which is very natural yet underexplored in the robotics community. We propose a control framework to design provably stabilizing tactile feedback policies by exploiting the local complementarity structure of contact dynamics. Lastly\, inspired by the connection between rectified linear unit (ReLU) activation functions and linear complementarity problems\, we present a method to analyze stability of multi-contact systems in feedback with ReLU network controllers.

SUMMARY:ASSET Seminar: "Safety through Agility - Safe and Performant Control for Learning-Enabled Autonomous Systems" (Mangharam\, Penn)
DESCRIPTION:ABSTRACT:  \nWe present three approaches to combine formal methods\, control theory\, and machine learning for safe and performant autonomous systems.  \n\nSafe control for learning-enabled systems: We present our recent progress on how to learn safe adaptive behavior for highly interactive multi-agent systems. We will introduce how to quantify the uncertainty of closed-loop control systems using a frequentist method called conformal prediction and incorporate the uncertainty for safe perception-based control.\nLearning Introspective Control: Oftentimes the systems that we control operate under different conditions due to changing environments\, varying system parameters or changes in payload. As such\, we strive to develop computationally efficient\, data-driven system models that allow predictive controllers to adapt to changes in the environment in real-time. We focus on using Gaussian Processes as models to study the problem in the context of driving on surfaces with changing friction coefficients. \nDifferentiable Predictive Control: Finally\, we discuss the application of differentiable predictive control for large-scale urban road networks.\n\n  \n

SUMMARY:Fall 2023 GRASP SFI: Robert Baines\, ETH Zürich\, "Material system design for predictable shape-morphing robots"
DESCRIPTION:This is a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. This week’s speaker will be virtual.  \nABSTRACT\nRobots are traditionally designed with immutable physical hardware and control policies that make them specialized for repetitive\, structured tasks and environments. This talk presents work toward robots that actively change shape to accomplish a variety of tasks in diverse environments. Shape-changing robots are pursued at two levels. First\, I will discuss the design and modeling of shape-morphing components\, including variable stiffness materials and variable-trajectory soft actuators. Component-level analysis leads to insight into how actively tunable stiffness differentials can yield myriad deformations. Inverse models that recapitulate shape-morphing components’ highly nonlinear geometric and material behavior allow for systematic mechanical programming of shape-morphing robotic function. These foundational studies inform the second part of the talk\, in which I will discuss how shape-morphing components are applied to create an adaptive amphibious quadruped robot. Harnessing active stiffness-tuning materials\, the robot features limbs that switch between programmed shapes for effective propulsion in multiple environments. The robot testifies to the efficacy of “adaptive morphogenesis\,” a design strategy that leverages shape-morphing and gait adaptability to improve performance across multiple environments.

SUMMARY:MSE David P. Pope Distinguished Lecture: "Light\, Materials and Interfaces: The Complex Dance That Allows CLIP-based 3D Printing\," Stanford University
DESCRIPTION:Abstract\nThe production of polymer products relies largely on age-old molding techniques. A major reason for this is that additive methods have not delivered meaningful alternatives to traditional processes—until now. In this talk\, I will describe Continuous Liquid Interface Production (CLIP) technology\, which embodies a convergence of advances in software\, hardware\, and materials to bring the digital revolution to polymer additive manufacturing. CLIP uses software-controlled chemistry to produce commercial quality parts rapidly and at scale by capitalizing on the principle of oxygen-inhibited photopolymerization to generate a continual liquid interface of uncured resin between a forming part and a printer’s exposure window. Instead of printing layer-by-layer\, this allows layerless parts to ‘grow’ from a pool of resin\, formed by light. Compatible with a wide range of polymers\, CLIP opens major opportunities for innovative products across diverse industries. Previously unmakeable products are already manufactured at scale with CLIP\, including the large-scale production of running shoes by Adidas (Futurecraft 4D); mass-customized football helmets by Riddell; the world’s first FDA-approved 3D printed dentures; and numerous parts in automotive\, consumer electronics\, and medicine. At Stanford\, we are pursuing new advances including digital therapeutic devices in pediatric medicine\, new multi-materials printing approaches\, recyclable materials\, and the design of a high-resolution printer to advance technologies in the microelectronics and drug/vaccine delivery areas\, including novel microneedle designs as a potent vaccine delivery platform.

SUMMARY:MEAM Ph.D. Thesis Defense: "A Study of Hydrogel Mechanics with Application on the Fracture of Human Blood Clots"
DESCRIPTION:Loading of biological and synthetic hydrogels involves large deformations\, and there exists a large literature devoted to their experimental characterization. Analytical investigations have recognized the importance of contributions originating from the liquid phase\, and experiments have verified them. The liquid flux fields in these materials usually exhibit fully three-dimensional profiles and are time-dependent. This coupled mechanical-diffusional poroelastic problem is studied here within the framework of continuum poro-elasticity and presents an abundance of interesting phenomena. One such interesting observation in many experiments is the tendency of some hydrogel materials to expel liquid under tension. This behavior is well-documented in biologically swollen tissues\, but it appears to be absent from a majority of synthetic hydrogels which exhibit the more common behavior of absorbing liquid under tension. In this thesis the poro-elastic fracture of hydrogel materials is studied and the energy release rate\, a fundamental quantity of fracture mechanics\, is computed. Liquid flow is shown to contribute significantly to fracture\, and it can be utilized to design tough hydrogels. \nBeyond the theoretical investigations\, continuum poroelasticity is applied to the fracture behavior of human blood clots whose main component is a fibrin gel. Fibrin is a blood clotting protein and the main structural components of clots and thrombi. Different fibrin(ogen) concentrations\, types of loading (tension and shear)\, and geometries are used to study the dependencies of the toughness on the fibrin(ogen)\, showing that fracture toughness increases with fibrin(ogen) concentration. The poroelastic constitutive model used\, incorporating the intricate fibrin fiber mechanics\, captures well the experimental data. Insights for the microstructural process happening during fracture are provided through a combination of finite element results and microscopy imaging.

DESCRIPTION:This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. \nABSTRACT\nNow that a significant fraction of human knowledge has been shared through the Internet\, scraped and squashed into the weights of Large Language Models (LLMs)\, do we still need embodiment and interaction with the physical world to build representations? Is there a dichotomy between LLMs and “large world models”? What is the role of visual perception in learning such models? Can perceptual agents trained by passive observation learn world models suitable for control? \nTo begin tackling these questions\, I will first address the issue of controllability of LLMs. LLMs are stochastic dynamical systems\, for which the notion of controllability is well established: The state (“of mind”) of an LLM can be trivially steered by a suitable choice of input given enough time and memory. However\, the space of interest for control of an LLM is not that of words\, but that of “meanings” expressible as sentences that a human could have spoken and would understand. Unfortunately\, unlike controllability\, the notions of meaning and understanding are not usually formalized in a way that is relatable to LLMs in use today. \nI will propose a simplistic definition of meaning that reflects the functional characteristics of a trained LLM. I will show that a well-trained LLM establishes a topology in the space of meanings\, represented by equivalence classes of trajectories of underlying dynamical model (LLM). Then\, I will describe both necessary and sufficient conditions for controllability in such a space of meanings. \nI will then highlight the relation between meanings induced by a trained LLM upon the set of sentences that could be uttered\, and “physical scenes” underlying sets of images that could be observed. In particular\, a physical scene can be defined uniquely and inferred as an abstract concept without the need for embodiment\, a view aligned with J. Koenderink’s characterization of images as “controlled hallucinations.” \nLastly\, I will show that popular models ostensibly used to represent the 3D scene (Neural Radiance Fields\, or NeRFs) can at most represent the images on which they are trained\, but not the underlying physical scene. However\, composing a NeRF with a Latent Diffusion Model or other inductively-trained generative model yields a viable representation of the physical scene. Such a model class\, which can be learned through passive observations\, is a first albeit rudimentary Foundational Model of physical scenes in the sense of being sufficient for any downstream inference task based on visual data.

SUMMARY:ESE Fall Seminar - "Agile Design of Domain-Specific Accelerators and Compilers"
DESCRIPTION:With the slowing of Moore’s law\, computer architects have turned to domain-specific hardware accelerators to improve the performance and efficiency of computing systems. However\, programming these systems entails significant modifications to the software stack to properly leverage the specialized hardware. Moreover\, the accelerators become obsolete quickly as the applications evolve. What is needed is a structured approach for generating programmable accelerators and for updating the software compiler as the accelerator architecture evolves with the applications. In this talk\, I will describe a new agile methodology for co-designing programmable hardware accelerators and compilers. Our methodology employs a combination of new programming languages and formal methods to automatically generate the accelerator hardware and its compiler from a single specification. This enables faster evolution and optimization of accelerators\, because of the availability of a working compiler. I will showcase this methodology using Amber\, a coarse-grained programmable accelerator for imaging and machine learning (ML) we designed and fabricated using our flow in TSMC 16 nm technology. I will show how we agilely evolved Amber into Onyx\, our next generation accelerator\, using an application-driven design space exploration framework called APEX enabled by our hardware-compiler co-design flow.

SUMMARY:ASSET Seminar: "Getting Computers to Do What We Want: Programming Meets Machine Learning" (Michael Littman\, Brown University)
DESCRIPTION:ABSTRACT: \nIt is immensely empowering to delegate information processing and automation work to machines and have them carry out difficult tasks on our behalf. But programming computers is hard. The traditional approach to this problem is to try to fix people: They should work harder to learn to code. In this talk\, I argue that a promising alternative is to meet people partway. Specifically\, powerful new approaches to machine learning provide ways to infer intent from disparate signals and\, with your help\, could help make it easier for everyone to get computational help with their vexing problems. \n

SUMMARY:Fall 2023 GRASP SFI: Andy Zeng\, Google DeepMind\, "From words to actions"
DESCRIPTION:This is a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. \nABSTRACT\nThe rise of recent Foundation models (and applications e.g. ChatGPT) offer an exciting glimpse into the capabilities of large deep networks trained on Internet-scale data. They hint at a possible blueprint for building generalist robot brains that can do anything\, anywhere\, for anyone. Nevertheless\, robot data is expensive – and until we can bring robots out into the world (already) doing useful things in unstructured places\, it will be challenging to match the same amount of diverse data being used to train e.g. large language models today. In this talk\, I will briefly discuss some of the lessons we’ve learned while scaling real robot data collection\, how we’ve been thinking about Foundation models\, and how we might bootstrap off of them (and modularity) to make our robots useful sooner.

SUMMARY:CBE Seminar: "Statistical Teleodynamics: A Unified Theory of Emergent Arbitrage Equilibrium Phenomena in Active and Passive Matter" (Venkatasubramanian\, Columbia University)
DESCRIPTION:The physics of active matter\, such as bacterial colonies and bird flocks\, exhibiting interesting self-organizing dynamical behavior has gained considerable importance in recent years. Recent theoretical advances use techniques from hydrodynamics\, kinetic theory\, and non-equilibrium statistical physics. However\, for biological agents\, these don’t seem to recognize explicitly their critical feature\, namely\, the role of survival-driven purpose and the attendant pursuit of maximum utility. In this talk\, I will present a novel game-theoretic framework\, statistical teleodynamics\, that accounts for this feature explicitly and shows how it can be integrated with conventional statistical mechanics to develop a unified theory of arbitrage equilibrium in active and passive matter. \nThe theory proposes a spectrum of self-actualizing capabilities\, going from none to completely strategic decision-making\, and envisions the various examples of active matter systems occupying someplace in this spectrum. I will show how statistical teleodynamics reduces to familiar results in statistical mechanics in the limit of zero self-actualization. At the other extreme\, in an economic setting\, it provides novel insights into the emergence of income distributions and their fairness in an ideal free-market society. As examples of agents in between these limits\, I will discuss how the theory predicts pattern formation in mussel beds\, the emergence of ant craters\, and the flocking of birds.

SUMMARY:MSE Seminar: "Nanomaterials Enable Delivery of Genetic Material Without Transgene Integration in Mature Plants" University of California - Berkeley
DESCRIPTION:Genetic engineering of plants is at the core of sustainability efforts\, natural product synthesis\, and agricultural crop engineering. The plant cell wall is a barrier that limits the ease and throughput with which exogenous biomolecules can be delivered to plants. Current delivery methods either suffer from host range limitations\, low transformation efficiencies\, tissue regenerability\, tissue damage\, or unavoidable DNA integration into the host genome. Here\, we demonstrate efficient diffusion-based biomolecule delivery into tissues and organs of intact plants of several species with a suite of pristine and chemically-functionalized high aspect ratio nanomaterials [1]. Efficient DNA delivery and strong protein expression without transgene integration is accomplished in mature Nicotiana benthamiana\, Eruca sativa (arugula)\, Triticum aestivum (wheat) and Gossypium hirsutum (cotton) leaves and arugula protoplasts [2]. Notably\, we demonstrate that transgene expression is transient and devoid of transgene integration into the plant host genome\, of potential utility for easing regulatory oversight of transformed crops as genetically modified organisms (GMOs) [3\, 4]. We also demonstrate a nanoparticle-based strategy in which small interfering RNA (siRNA) is delivered to mature Nicotiana benthamiana leaves and effectively silence a gene with 95% efficiency. We find that nanomaterials both facilitate biomolecule transport into plant cells\, while also protecting polynucleotides such as RNA from nuclease degradation. DNA origami and nanostructures and gold nanoparticles further enable siRNA delivery to plants [5]\, which we use to elucidate force-independent transport phenomena of nanoparticles to the plant cell wall [6\, 7]. Lastly\, we demonstrate protein delivery with newly-discovered peptide-based nanoparticles towards DNA-free genome editing. Our work provides a tool for species-independent\, targeted\, and passive delivery of genetic material\, without transgene integration\, into plant cells for diverse plant biotechnology applications.  \n1.

SUMMARY:BE Seminar: "Synthetic mucins: from new chemical routes to engineered cells" (Jessica R. Kramer\, University of Utah)
DESCRIPTION:Mucus is essential for life and serves as a barrier to hydrate\, lubricate\, and protect tissues. Mucin glycoproteins are the major component of mucus. There are 20+ mucin genes with variable expression patterns\, splicing\, and post-translational glycosylation that result in structures with discrete biochemical functions. Mucins play roles in infection\, immunity\, inflammation and cancer. Such diversity has challenged study of structure-function relationships. The Kramer lab is developing scalable methods\, based on polymerization of amino acid N-carboxyanhydrides\, to synthesize glycoproteins that capture the chemical and physical properties of native mucins. We are utilizing these synthetic mucins to engineer the glycocalyx of live cells to shed light on the role of glycans in health and disease. Areas of focus for our lab are progression of epithelial cancers\, and pathogen infection processes. \n

SUMMARY:MSE PhD Defense: "Highly Controlled Transition Metal and Transition Metal Oxide Nanocrystals for Enhanced Catalytic and Magnetic Properties" Daniel Rosen
DESCRIPTION:This work presents the precise synthesis\, characterization\, and property analysis of transition metal and transition metal oxide nanocrystals (NCs). Specifically\, the interface between catalytic and magnetic properties is explored using precisely defined NCs. The methods of NC synthesis and characterizations are discussed including an in-depth discussion of Extended X-ray Absorption Fins Structure (EXAFS) based nanothermometry methods developed in this work. The ability to control the atomic structure of NCs is discussed in the context of rapidly induced intermetallic phase transitions for the electrochemical Oxygen Reduction Reaction (ORR). We discuss the use of these precisely designed NCs for their use in thermal catalysis in the presence of an induction field to show how the magnetic properties of NCs can enhance the catalytic properties specifically CO Oxidation and Cinnamaldehyde Hydrogenation. The discussion of nanothermometry is extended as an in-operando technique to better describe the magnetic effects of inductively enhanced CO Oxidation in flow. In the final chapter\, the precise synthesis of NCs is explored in order to generate both novel materials as well as materials synthesized through non solvothermal methods. The generation of core-shell materials in the context of ORR and the electrochemical Oxygen Evolution Reaction (OER) are discussed. These core-shell materials show great potential for magnetically enhanced catalysis\, and this possibility is discussed as a possible future work.

SUMMARY:PICS Colloquium: "Wind\, Waves\, and Wakes: Large Eddy Simulation of Full-Scale Offshore Wind Farms under Realistic Atmospheric and Oceanic Conditions"
DESCRIPTION:Ambitious targets on aggressive timelines have been heralded for the development of offshore wind energy in the United States\, especially in New Jersey with a target of 11 GW (nearly 2/3 of current generation) of offshore wind energy capacity by 2040. With these targets and timelines\, immense effort is required to minimize risk (financial risk\, energy system risk\, and environmental risk)\, and computational simulations of full-scale offshore wind farms under realistic atmospheric and oceanic conditions will be absolutely critical in siting\, operations\, forecasting\, and understanding potential climate impacts. Such computational simulations are exceptionally challenging due to the multi-physics\, multi-scale nature of the problem from the smallest scales of the waves and the turbulence to the multi-kilometer scales of the farms. As a result\, for full-scale farm simulations with Large Eddy Simulation (LES)\, much of the key physical phenomena will be unresolved. In this seminar\, our efforts toward full-scale farm simulations with LES will be discussed. Our computationally efficient wall-modeled LES framework combines an Actuator Disk Model for the wind turbines with a drag force-based model for the influence of the oceanic waves on the marine atmospheric boundary layer\, which avoids ad hoc parameterization of oceanic waves as a simple roughness but at no increased cost. Our wall-modeled framework is shown to be orders of magnitude less expensive than wall-resolved/wave-phase-resolved simulations without any loss in accuracy. Recent efforts have focused on extending our approach to oceanic wave spectra\, including a dynamic procedure to characterize completely unresolved waves\, and to swell. Finally\, using our framework\, the sensitivity of offshore wind farms to wave characteristics is assessed to demonstrate that the waves are a leading order influence on offshore wind farm performance.

SUMMARY:MEAM Seminar: "Bringing Microrobots into Biomedicine"
DESCRIPTION:Recent progress in diverse disciplines such as soft matter physics\, nanoparticle synthesis\, nanomedicine\, and microbiology has enabled rich opportunities for translation of small-scale robots into medical applications. These robotic systems are providing innovative\, high-precision\, therapeutic and diagnostic approaches for the treatment of diseases associated with microbial biofilms and are rapidly moving from proof-of-concept studies to translational biomedical applications using ex vivo and animal models. I highlight recent progress using directed nanoparticle assembly to create adaptive\, reconfigurable\, microrobotic systems capable of treating and removing microbial biofilms from topographically complex\, difficult-to-access sites. These methods for disruption rely on both chemical and mechanical activity\, using iron oxide nanoparticles with dual functionality: catalytic properties for generating reactive species on-site and magnetic properties for controlled assembly and physical removal. This approach could lead to autonomous\, multifunctional antibiofilm platforms to advance current treatment modalities and other fields contending with harmful biofilms on hard-to-reach surfaces.

SUMMARY:CIS Seminar: "An Alternative View on AI:  Collaborative Learning\, Incentives\, and Social Welfare"
DESCRIPTION:Artificial intelligence (AI) has focused on a paradigm in which intelligence inheres in a single\, autonomous agent.  Social issues are entirely secondary in this paradigm.  When AI systems are deployed in social contexts\, however\, the overall design of such systems is often naive—a centralized entity provides services to passive agents and reaps the rewards.  Such a paradigm need not be the dominant paradigm for information technology.  In a broader framing\, agents are active\, they are cooperative\, and they wish to obtain value from their participation in learning-based systems.  Agents may supply data and other resources to the system\, only if it is in their interest to do so.  Critically\, intelligence inheres as much\nin the overall system as it does in individual agents\, be they humans or computers. This is a perspective that is familiar in the social sciences\, and a key theme in my work is that of bringing economics into contact with foundational issues in computing and data sciences.  I’ll emphasize some of the mathematical challenges that arise at this tripartite interface.
