SUMMARY:MEAM Seminar: "Architecture in Biological Materials: A Template for Toughness Enhancement\, or a Siren Song?"
DESCRIPTION:Structural biological materials\, such as animal bones and shells\, display remarkable mechanical properties despite being composed of quite simple and ordinary constituent materials. For example\, the toughness of nacre\, a structural biological material found in the shells of some mollusks\, is orders of magnitude higher than that of its primary constituent—the calcium based mineral aragonite. A number of structural biological materials that display toughness enhancement also possess a lamellar architecture consisting of alternating layers of ceramic and organic phases. It is believed that a structural biological material’s intricate architecture—the geometric arrangement of these phases—is responsible for the observed property enhancements. Within the bio-mimetics community\, there is currently great interest in reproducing these architectures in synthetic materials using micro-fabrication and 3D printing in order to achieve the property enhancements observed in structural biological materials. \nIn this talk I will present experimental and computational mechanics results that show that correctly identifying the connection between a structural biological material’s architecture and any property enhancements can be a very delicate process. Specifically\, I will present experiments that characterize the toughness properties of the skeletal elements of the marine sponge Euplectella aspergillum\, called spicules. I will show that despite possessing a lamellar architecture that is very similar to that seen in nacre\, the spicules do not display a significant toughness enhancement. Through mechanics modeling\, I argue that the spicule’s lamellar architecture is connected to their ability to bend more without failing\, i.e.\, to their strength\, rather than their toughness. These results serve as a reminder that any efforts aimed at reproducing a structural biological material’s architecture and property enhancements in synthetic materials should be prefaced by a careful investigation of the structural biological material itself. \nReferences \n[1] Monn\, Michael A.\, James C.

SUMMARY:CIS Seminar: “Learning in dynamic environments”
DESCRIPTION:Abstract: \nIn many online systems participants use data and algorithms to experiment and learn how to best use the system. Examples include traffic routing as well as online auctions. Game theory classically studies Nash equilibrium as the outcome of selfish interaction\, and has many examples illustrating that selfish behavior can lead to suboptimal outcome for all participants. Over the last decade\, we developed good understanding how to quantify the impact of strategic user behavior on overall performance in Nash equilibria of games. In this talk we will focus on games where players use a form of learning that helps them adapt to the environment. We ask if the quantitative guarantees obtained for Nash equilibria extend to such out of equilibrium game play\,  possibly even in dynamically changing environments?

SUMMARY:ESE Seminar: "Foundations of Deep Learning and Applications in Medicine"
DESCRIPTION:Abstract: Recent advances in machine learning\, computer vision\, natural language processing\, and robotics\, offer a tremendous opportunity to transform medicine\, from reactive and hospital centered to proactive and patient-centered. To fulfill this promise\, new methods need to be developed which are more interpretable\, can handle data at multiple spatial and temporal scales\, and are robust to data heterogeneity and limited amounts of annotations. The first part of this talk will overview our recent work on the theory of deep learning\, including sufficient conditions to guarantee that local minima are globally optimal\, as well as an analysis of the optimization and regularization properties of dropout. The second part of this talk will overview our recent work on the development of methods for interpreting biomedical datasets arising in blood cell analysis\, regenerative medicine\, digital pathology\, brain imaging\, surgery and rehabilitation therapy.

SUMMARY:CBE Seminar: "Toward Platinum-free Fuel Cells for Affordable Zero-emission Vehicles”
DESCRIPTION:Abstract: \nOne of the grand challenges facing humanity today is the development of an alternative energy system that is safe\, clean\, and sustainable. A Distributed Renewable Electrochemical Energy and Mobility System (DREEMS) can meet this challenge. At the foundation of this new energy system\, we have chosen to study fuel cells\, electrolyzers\, and flow batteries. For all these devices polymer electrolytes play a critical role in controlling their performance\, cost\, and durability\, and thus their economic viability. In this presentation\, I will focus on our recent work on Hydroxide Exchange Membrane Fuel Cells (HEMFCs). More specifically\, I will focus on our recent discovery of a new family of polymer hydroxide (and other anions) conductors that is chemically stable\, ionically conductive\, and mechanically robust; and HEMFCs with this new class of polymers showed record fuel cell performance and stability at 95 ºC. I will also briefly introduce a new class of crystalline porous polymers that are the most stable among all crystalline porous materials.

SUMMARY:PICS Seminar: Isogeometric Methods for Solids\, Structures\, and Fluid-Structure Interaction: From Early Results to Recent Developments
DESCRIPTION:Abstract: This presentation is focused on Isogeometric Analysis (IGA) with applications to solids and structures\, starting with early developments and results\, and transitioning to more recent work. Novel IGA-based thin-shell formulations are discussed\, and applications to progressive damage modeling in composite laminates due to low-velocity impact and their residual-strength prediction are shown. Fluid–structure interaction (FSI) employing IGA is also discussed\, and a novel framework for air-blast-structure interaction (ABSI) based on an immersed approach coupling IGA and RKPM-based Meshfree methods is presented and verified on a set of challenging examples. The presentation is infused with examples that highlight effective uses of IGA in advanced engineering applications.

SUMMARY:PRiML Seminar: "Nonconvex Optimization Meets Statistics: A Few Recent Stories"
DESCRIPTION:Recent years have seen a flurry of activity in solving statistical estimation and learning problems via nonconvex optimization. While conventional wisdom often takes a dim view of nonconvex optimization algorithms due to their susceptibility to spurious local minima\, simple iterative methods such as gradient descent have been remarkably successful in practice. The theoretical footings\, however\, had been largely lacking until recently. This talk presents two recent stories about nonconvex statistical estimation\, which highlight the important role of statistical models in enabling efficient nonconvex optimization. The first story is about randomly initialized nonconvex methods for a phase retrieval problem: even without careful initialization\, simple algorithms like gradient descent provably find the global solution within a logarithmic number of iterations. The second story is concerned with uncertainty quantification for nonconvex low-rank matrix completion. We develop a de-biased estimator — on the basis of a nonconvex estimate — that enables optimal construction of confidence intervals for the missing entries of the unknown matrix. All of this is achieved via a leave-one-out statistical analysis framework\, which is very powerful in handling and decoupling complicated statistical dependency.\n\n\nThis is joint work with Cong Ma\, Yuling Yan\, Yuejie Chi\, and Jianqing Fan.
