SUMMARY:MEAM Seminar: "The Challenges and Opportunities of Battery-Powered Flight"
DESCRIPTION:Sustainable transportation and aviation are critical to address climate change and renewable energy powered battery electric vehicles represent a promising path towards this goal. I will discuss the performance metrics needed of batteries for electric land and air vehicles\, and assess the energy-efficiency of electric vertical take-off and landing (eVTOL) aircraft compared to ground vehicles.[1] Identifying the challenging but achievable battery performance requirements for eVTOL\, I will discuss our approach to achieve simultaneously high specific energy and power by using lithium metal anodes\, enabled through a new density-driven dendrite suppression mechanism realized through a soft polymer-ceramic composite separator[2]. I will discuss the unique performance failure mode related to power fade for eVTOLs rather than energy fade for electric vehicles. Following this\, I will discuss the requirements and challenges for all-electric battery-powered single and twin-aisle aircraft and outline battery chemistry innovations that offer a pathway to approaching these requirements.[3] I will discuss two key tools to accelerate the innovation timeline for these battery chemistries: (i) in-situ and operando characterization[4] (ii) closed-loop battery material discovery with physics based simulation and robotic experimentation.[5] \nReferences: [1] Sripad\, Viswanathan\, Proceedings of the National Academy of Sciences 9\, 2021 118 (45) e2111164118 [2] Fu et al.\, Nature Materials\, (2020)\, 19\, 758–766.

SUMMARY:CIS Grace Hopper Lecture: "Data Privacy is Important\, But It's Not Enough"
DESCRIPTION:Our current data ecosystem leaves individuals\, groups\, and society vulnerable to a wide range of harms\, ranging from privacy violations to subversion of autonomy to discrimination to erosion of trust in institutions. In this talk\, I’ll discuss the Data Co-ops Project\, a multi-institution\, multi-disciplinary effort I co-lead with Kobbi Nissim. The Project seeks to organize our understanding of these harms and to coordinate a set of technical and legal approaches to addressing them. In particular\, I’ll mention recent joint work with Ayelet Gordon and Alex Wood\, wherein we argue that legal and technical tools aimed at controlling data and addressing privacy concerns are inherently insufficient for addressing the full range of these harms.

SUMMARY:ASSET Seminar: Scallop: A Language for Neuro-Symbolic Programming\, Mayur Naik (University of Pennsylvania)
DESCRIPTION:ABSTRACT: \nNeurosymbolic learning is an emerging paradigm which\, at its core\, combines the otherwise complementary worlds of classical algorithms and deep learning; in doing so\, it ushers in more accurate\, interpretable\, and domain-aware solutions for today’s most complex machine learning challenges.  I will begin by reviewing the various fundamentals\, such as algorithmic supervision\, symbolic reasoning\, and differentiable programming\, which have defined this intersection thus far.  I will then present Scallop\, a general-purpose programming language that allows for a wide range of modern neurosymbolic learning applications to be written and trained in a data and compute efficient manner.  Scallop is able to achieve these goals through three salient overarching design decisions: 1) a flexible symbolic representation that is based on the relational data model; 2) a declarative logic programming language that builds on Datalog; and 3) a framework for automatic and efficient differentiable reasoning that is based on the theory of provenance semirings. I will present case studies demonstrating how Scallop expresses algorithmic reasoning in a diverse and challenging set of AI tasks\, provides a succinct interface for machine learning programmers to integrate logical domain-specific knowledge\, and outperforms state-of-the-art deep neural network models in terms of accuracy and efficiency. \nThis is joint work with PhD students Ziyang Li and Jiani Huang.

SUMMARY:Fall 2022 GRASP SFI: Nitin Sanket\, Worcester Polytechnic Institute\, "AI-Powered Robotic Bees: A Journey Into The Mind And Body!"
DESCRIPTION:This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. \nABSTRACT\nThe human fascination to mimic ultra-efficient living beings like insects and birds has led to the rise of small autonomous robots. Smaller robots are safer\, more agile and are task-distributable as swarms. One might wonder\, why do we not have small robots deployed in the wild today? Smaller robots are constrained by a severe dearth of computation and sensor quality. To further exacerbate the situation\, today’s mainstream approach for autonomy on small robots relies on building a 3D map of the scene that is used to plan paths for executing a control algorithm. Such a methodology has severely bounded the potential of small autonomous robots due to the strict distinction between perception\, planning\, and control. Instead\, we re-imagine each agent by drawing inspiration from insects at the bottom of the size and computation spectrum. Specifically\, each of our agents is made up of a series of hierarchical competences built on bio-inspired sensorimotor AI loops by utilizing the action-perception synergy. Here\, the agent controls its own movement and physical interaction to make up for what it lacks in computation and sensing. Such an approach imposes additional constraints on the data gathered to solve the problem using Active and Interactive Perception. I will present how the world’s first prototype of a RoboBeeHive was built using this philosophy. Finally\, I will conclude with a recent theory called Novel Perception that utilizes the statistics of motion fields to tackle various class of problems from navigation and interaction. This method has the potential to be the go-to mathematical formulation for tackling the class of motion-field-based problems in robotics.

SUMMARY:ESE 2022 Jack Keil Wolf Lecture - "Sustaining the Semiconductor Revolution: Challenges and Opportunities"
DESCRIPTION:Advancements in semiconductor integrated circuit (IC) “chip” technology over the past 60+ years have enabled exponential growth in chip functionality with exponential reduction in cost per transistor\, resulting in the proliferation of information and communication devices and systems\, with revolutionary impact on society; today cloud computing\, big data and artificial intelligence are driving the digital transformation of all industries. As fundamental limits approach for transistor miniaturization\, alternative\, more innovative approaches to improving chip performance will be needed. In this talk I will give some examples of such approaches and discuss opportunities to collaborate in diversifying talent development pathways to meet the growing innovation and workforce development needs of the U.S. semiconductor microelectronics industry\, spurred by the CHIPS and Science Act of 2022.

SUMMARY:MSE Seminar: “Biomineralogical Signatures of Pathlogical Mineralization”
DESCRIPTION:Pathological calcification is a wide-spread phenomenon in the human body\, in which calcium minerals form in soft tissues and are found in both healthy and diseased tissues. One example are microcalcifications (MCs)\, which are primarily biological apatite and occur in cancerous and benign breast pathologies. MCs are key mammographic indicators\, however\, little is known about their materials properties and associated organic matrix\, or their correlation to breast cancer prognosis. Outside the clinic\, numerous microcalcification compositional metrics (e.g.\, carbonate and metal content) are linked to malignancy\, yet microcalcification formation is dependent on microenvironmental conditions\, which are notoriously heterogeneous in breast cancer. We have interrogated multiscale heterogeneity in calcifications from over 20 breast cancer patients. Employing an omics-inspired approach\, for each microcalcification we define a “biomineralogical signature” combining metrics derived from Raman microscopy and energy dispersive spectroscopy. We observe that 1) calcifications cluster into physiologically relevant groups reflecting tissue type and local malignancy; 2) carbonate content exhibits substantial intratumor heterogeneity; 3) trace metals including zinc\, iron\, and aluminum\, are enhanced in malignant-localized calcifications; 4) the lipid-to-protein ratio within calcifications is lower in patients with poorer prognosis\, suggesting that expanding diagnostic metrics to include “mineral-entrapped” organic material may hold prognostic promise.  This multimodal methodology lays the groundwork for establishing MC heterogeneity in the context of breast cancer biology\, and has the potential to be applied to other pathological minerals\, as well as in vitro models of mineralization.

SUMMARY:Fall 2022 GRASP Seminar: Ankit Shah\, Brown University\, "Training Robots Like Apprentices"
DESCRIPTION:*This is a HYBRID Event with in-person attendance in Levine 307 and virtual attendance via Zoom. \nABSTRACT\nDomains such as high-mix manufacturing\, domestic robotics\, space exploration\, etc.\, are key areas of interest for robotics. Yet\, the difficulty of anticipating the role of robots in these domains is a crucial hurdle for the adoption of robots. Developing robots that can be re-programmed easily during deployment by domain experts without requiring extensive programming knowledge\, or in other words robotic apprentices that learn from experts will drive the next wave of robotics adoption. \nIn this talk\, I present a multi-modal Bayesian framework for teaching a robot learner to identify the teacher’s intended task from natural teaching modalities such as demonstrations\, and acceptability assessments of the execution. The framework centers on using formal languages such as LTL to model the task specification\, and using probabilistic reasoning to reason about the ambiguity in natural teaching modalities. Utilizing the Bayesian framework\, we can teach the robot the task specifications from demonstrations\, and the robot models its updated belief over specifications as a distribution of logical formulas. We propose Planning with Uncertain Specifications (PUnS)\, a novel framework to reason about the uncertainty of task specifications while computing the robot policy. We also demonstrate how using formal languages along with active learning can help the robot refine its belief efficiently. Finally we demonstrate how the temporal abstractions afforded by temporal logics in particular can help the robot learn to reuse policies from one task to accomplish other closely related tasks without any additional learning.

SUMMARY:BE Seminar: "Cellular and Acellular Strategies for Heart and Lung Repair" (Ke Cheng\, UNC/NCSU)
DESCRIPTION:This is a hybrid seminar: Check email for the zoom link and passcode. \n“Cellular and Acellular Strategies for Heart and Lung Repair” \nTherapeutic tissue regeneration using stem cells has been hampered by the controversial identity of resident stem cells\, low cell retention/engraftment\, tumorigenecity and immunogenicity issues. Taking a bioengineering/biomaterials approach\, this lecture will introduce the uses of drug delivery and biomaterials strategies to generate more potent cell therapies for heart and lung diseases. In addition\, a pharmacoengineering approach is taken to refine cell therapies by developing acelluar therapeutics such as stem cell-derived secretome and exosomes in the setting of heart and lung regeneration. This lecture will also mention a couple of stories in translating bench research into IND-enabled clinical trials on cell-based therapies.

SUMMARY:Fall 2022 GRASP on Robotics: Matthew Johnson-Roberson\, Carnegie Mellon University\, “Lessons from the Field: Deep Learning and Machine Perception for field robots”
DESCRIPTION:This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. \n  \nABSTRACT\nMobile robots now deliver vast amounts of sensor data from large unstructured environments. In attempting to process and interpret this data there are many unique challenges in bridging the gap between prerecorded data sets and the field. This talk will present recent work addressing the application of machine learning techniques to mobile robotic perception. We will discuss solutions to the assessment of risk in self-driving vehicles\, thermal cameras for object detection and mapping and finally object detection and grasping and manipulation in underwater contexts. Real field data will guide this process and we will show results on deployed field robotic vehicles.

SUMMARY:PICS Seminar: "A Non-local Plasticity Model for Porous Metals with Deformation-induced Anisotropy: Mathematical and Computational Issues"
DESCRIPTION:A non-local (gradient) plasticity model for porous metals that accounts for deformation-induced anisotropy is presented. The model is based on the work of Ponte Castañeda and co-workers on porous materials containing randomly distributed ellipsoidal voids. It takes into account the evolution of porosity and the evolution/development of anisotropy due to changes in the shape and the orientation of the voids during plastic deformation. A “material length” λ is introduced and a “non-local” porosity is defined from the solution of a modified Helmholtz equation with appropriate boundary conditions. At a material point located at x \, the non-local porosity f (x) \, can be identified with the average value of the “local” porosity floc (x) over a sphere of radius 3Rλ centered at x. \nThe same approach is used to formulate a non-local version of the Gurson isotropic model. The mathematical character of the resulting incremental elastoplastic partial differential equations of the non-local model is analyzed. It is shown that the hardening modulus of the non-local model is always larger than the corresponding hardening modulus of the local model; therefore\, the non-local incremental problem retains its elliptic character\, and the possibility of discontinuous solutions is eliminated. A rate-dependent version of the non-local model is also developed. \nAn algorithm for the numerical integration of the non-local constitutive equations is developed\, and the numerical implementation of the boundary value problem in a finite element environment is discussed. An analytical method for the required calculation of the eigenvectors of symmetric second-order tensors is presented. The non-local model is implemented in ABAQUS via a material “user subroutine” (UMAT or VUMAT) and the coupled thermo-mechanical solution procedure\, in which temperature is identified with the non-local porosity. Several example problems are solved numerically and the effects of the non-local formulation on the solution are discussed. In particular\, the problems of plastic flow localization in plane strain tension\, the plane strain mode-I blunt crack tip under small-scale-yielding conditions\, the cup-and-cone fracture of a round bar\, and the Charpy V-notch test specimen are analyzed.
