Tissue reorganization can be rapid and dramatic\, often occurring through striking embryo-scale flows that are mediated by the coordinated actions of hundreds or thousands of cells. In Drosophila\, cell rearrangements in the embryonic epithelium rapidly narrow and elongate the tissue\, producing a tissue flow that doubles the length of the body axis in just 30 minutes. These types of tissue movements can be driven by internal forces generated by the cells themselves or by external forces. While much is known about the molecules involved in these cell and tissue movements\, it is not yet clear how these molecules work together to coordinate cell behaviors\, give rise to emergent tissue mechanics\, and generate coherent flows at the embryo scale. To gain mechanistic insight into this problem\, my lab combines genetic and biophysical approaches with emerging optogenetic technologies for manipulating molecular and mechanical activities inside cells with high precision. I will discuss some of our recent findings on how cellular properties and mechanical forces are regulated in the Drosophila embryo to allow (or prevent) rapid cell rearrangements and tissue flows during specific events in embryonic development.

Although real physical processes are very complicated\, useful models abstract away the irrelevant degrees of freedom to give parsimonious representations. In contrast\, overly complex models can be difficult to evaluate\, suffer from numerical instabilities\, and may overfit data. They also obscure useful insights into the relationship among different physical systems. I use information geometry to explore the role of simplicity in scientific explanation. I interpret a multi-parameter model as a manifold embedded in the space of all possible data\, with a metric induced by statistical distance. These manifolds are often bounded and very thin\, so they are well-approximated by a low-dimensional\, simple model. For many types of models\, there is a hierarchy of natural approximations that reside on the manifold’s boundary. These approximations are not black-boxes. They remain expressed in terms of the relevant combinations of mechanistic parameters and reflect the physical principles on which the complicated model was built. They can also be constructed systematically using computational differential geometry\, as I illustrate with examples from physics and systems biology URL:https://seasevents.nmsdev7.com/event/ese-fall-colloquium-using-information-geometry-to-find-simple-models-of-complex-processes/ LOCATION:Raisler Lounge (Room 225)\, Towne Building\, 220 South 33rd Street\, Philadelphia\, PA\, 19104\, United States CATEGORIES:Colloquium ORGANIZER;CN="Electrical and Systems Engineering":MAILTO:eseevents@seas.upenn.edu END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20221115T120000 DTEND;TZID=America/New_York:20221115T133000 DTSTAMP:20260405T155854 CREATED:20221111T214536Z LAST-MODIFIED:20221111T214536Z UID:10007359-1668513600-1668519000@seasevents.nmsdev7.com SUMMARY:ESE Ph.D. Thesis Defense - "Learning and Control of Network Phenomena" DESCRIPTION:The intersection of dynamical systems and networks are used to model a huge variety of phenomena such as the spread of disease\, multi-agent systems\, opinions in social networks\, and more. Many properties of these network phenomena can be understood by examining the eigenvalue spectrum of a matrix representation of the underlying graph. Using this intuition\, this thesis explores the learning and control of network phenomena. First\, I present techniques for matching individuals across correlated networks and learning the spectra of a graph matrix using only the sparse output measurements of a networked dynamical system with periodic inputs. Next\, I present a data-driven framework for multi-task learning and non-linear control of epidemics. Finally\, I propose a new architecture for signal processing on higher-order graphs\, along with a new transferability bound on the performance of graph neural networks via spectral similarity. This transferability result is valid for arbitrary graphs regardless of their structure\, resulting in the first bound on the transferability of a machine learning approach for higher-order graphs.

Our approach requires minimal modification to existing ML systems\, and improves robustness to prior probability shift. The improvement comes from mitigating unobserved confounders that cause the targets\, but not the input. We refer to them as target-causing confounders. These confounders induce spurious dependencies between the input and targets. This poses a problem for the conventional approach to multitask learning\, due to its assumption that the targets are conditionally independent given the input. Our proposed approach takes into account the dependency between the targets in order to alleviate target-causing confounding. All that is required in addition to usual practice is to estimate the joint distribution of the targets to switch from discriminative to generative classification\, and to predict all targets jointly. Our results on the Attributes of People and Taskonomy datasets reflect the conceptual improvement in robustness to prior probability shift.

Coordinated motor patterns consistent with the embodiment emerge from multiple chaotic elements coupled through body-environment physics. \nIn humans\, the above principle may drive early motor development. And the resulting sensory-motor information can be captured by self-organizing neural circuits\, forming the basis of cognitive structures. \nIn order to investigate this hypothetical scenario\, we constructed a simulation model of a human fetus. It consists of a musculo-skeletal body\, whole body cutaneous receptors (tactile)\, uterus and amniotic fluid\, neuronal model of spine and medulla\, and a whole neocortex model with self-organizing neural network. \nWith very little “innate” functional neural circuits\, the model acquired various behavior patterns that comply with its embodiment\, and the neural model self organizes to capture the embodied information structure. It exhibits spontaneous motor development and sensory-motor map organization comparable to human data. Also\, by changing the model parameters\, we can simulate “atypical” development. \nOur series of experiments shows that sensory-motor experiences in the fetal period can be crucial to the formation of body representations and multi-modal sensory integration\, which are significantly affected under “preterm birth” conditions\, providing new insights about the developmental origins of social cognition and autism spectrum disorders.\nImplications for the next generation AI/robotics will also be discussed if time allows.

In particular\, autonomous racing is a domain that penalizes safe but conservative policies\, highlighting the need for robust\, adaptive strategies. Current approaches either make simplifying assumptions about other agents or lack robust mechanisms for online adaptation. In this talk we will explore research themes on perception\, planning and control at the limits of performance. We explore (1) How to generate the most competitive agents who dynamically balance safety and assertiveness by using distributionally robust online adaptation; (2) How to build the most efficient autonomous racecar with Multi-domain optimization across vehicle design\, planning and control; (3) How to combine previous system designs to auto-complete new designs with new requirements\, and (4) Understand the value of Cooperation in Multi-Agent Games. We realize all our research in the https://f1tenth.org autonomous racecar platform that is 10th the size\, but 10x the fun! The main takeaway from this talk is how you can get involved in very exciting research on safe autonomous systems.  I will also present projects on AV Gokart that we are doing in the Autoware Center of Excellence for Autonomous Driving at Pennovation.

NAB’s are widely used in many naval applications including ship propellers\, underwater fasteners\, pumps\, and valves. Traditional sand cast NAB alloys tend to have a large amount of waste material\, and reduced complexity in component geometry due to the limitations of the casting processing.  As a result\, NAB alloys are emerging as a viable alloy for additive manufacturing (AM) and therefore provides a new space to establish fundamental relationships between AM processing\, structure and properties. Of the additive processes\, wire arc additive manufacturing (WAAM) is an evolving technology for fabricating large-scale\, near net shape NAB components. It is understood that the high cooling rates achieved in WAAM prevent the precipitation of coarse rosette-like kI phase which usually form during the latter stages of solidification during the casting process. In this work\, the dislocation interactions with interfaces such as grain boundaries and precipitates will be used to understand fatigue life and crack initiation and growth behavior in these alloys during low-cycle and high-cycle fatigue.

Design-space size increases exponentially in the number of design parameters\, and synthesizing a single configuration for a device-scale application easily consumes hours\, so existing autotuners are frequently demonstrated with small kernels and few configurations to render the problem tractable. This dissertation shows that exploration of applications with more than 25 parameters mapped on reconfigurable SoCs exceeding 200K LUTs becomes feasible using the model-based approach we refine. We explore various techniques to reduce the tuning time. At the heart of our tuner are multi-fidelity models\, which enable discontinuation of unpromising builds in multi-stage CAD flows. We rearranged the build resources in a pipeline to improve the tuning performance and increase the utilization of build resources. Build failures and underperforming configurations are avoided using latency\, area\, critical path delay\, congestion\, error probability\, and build time prediction models. Next\, we introduce a novel model that combines the preexisting hierarchical and multi-fidelity models. The hierarchical model enables the decomposition of design spaces into exponentially smaller subspaces that can be explored faster. Also novel is the use of out-of-context compilation to lower the build time further. A tree-based model alleviates the long training times of Gaussian process models. To validate our approach\, we injected 29 – 44 parameters\, varying from compiler pragmas to CAD tool parameters\, in the Rosetta benchmarks. Compared to non-pipelined multi-fidelity Bayesian optimization\, our tuner succeeds 20% more often at finding mappings on the ZCU102\, and tuning runs are on average at least 2.2x shorter. Moreover\, it locates 3.6x faster solutions within 24 hours.

Millman\, Washington University School of Medicine) DESCRIPTION:This is a hybrid seminar which will be held in Glandt Forum (Singh Center) and via Zoom (link coming soon). \n“Developments in Stem Cell-Derived Islets for Diabetes Cell Replacement Theory” \nCellular and tissue engineering promises new therapeutic options for people suffering from a wide range of diseases. Differentiation of stem cells is a powerful renewable source of these functional replacement cells and tissues that can be grown in the laboratory. Diabetes is cause by the death or dysfunction of insulin-secreting islets\, which are a tissue type found in the pancreas that contain β cells and other endocrine cell types. We have recently developed approaches combining modulating the actin cytoskeleton and signal transduction pathways during differentiation to produce stem cell-derived islets (SC-islets) capable of undergoing glucose-stimulated insulin secretion\, their primary function. We have further expanded this approach to make SC-islets from patients with diabetes and used CRISPR-Cas9 to correct their diabetes-causing mutations. Upon transplantation into mice with severe pre-existing diabetes\, these SC-islets rapidly restore normoglycemia and can maintain this functional cure for a year. Our hope is that one day this technology can be used to replace unhealthy islets in patients for therapy and provide a better disease-in-a-dish model to discover new drugs to prevent\, stop\, or reverse diabetes progression.

Spatial robustness of STL specifications\, quantifying permissible spatial perturbations\, has been widely studied in the literature. However\, despite the importance of various time-critical systems\, temporal robustness of STL has not yet been studied in depth nor has been used for control design. \nIn the first part of this thesis\, we establish a comprehensive theoretical framework for temporal robustness of STL. We define synchronous and asynchronous temporal robustness and show that these notions quantify the robustness with respect to synchronous and asynchronous time shifts in the predicates of the underlying signal temporal logic specification. We further prove that synchronous temporal robustness upper bounds asynchronous temporal robustness. Moreover\, we show under which conditions these two robustness notions are equivalent. Introduced synchronous and asynchronous notions are directional and consider either left or right perturbations. Due to this reason we additionally define and study the combined temporal robustness which simultaneously considers left and right time shifts. \nIn the second part of this thesis\, we focus on applications of various robustness functions to robust planning and control design questions. We first propose solutions to the temporally-robust control synthesis problem by presenting Mixed-Integer Linear Programming (MILP) encodings for derived temporal robustness notions. Second\, we solve the spatially-robust control synthesis problem and show how to adapt the smooth operator for space robustness maximization. Furthermore\, we propose possible distributed solutions to centralized multi-agent planning problems. Through various simulations\, as well as experiments on actual robotic systems\, we show that our presented solutions are computationally efficient as well as can be used in a wide variety of applications.

The multi-dimensional workload algorithm incorporates physiological metrics to estimate overall workload and its components (i.e.\, cognitive\, speech\, auditory\, visual and physical). The algorithm is sensitive to changes in a human’s individual workload components and overall workload across domains\, human-robot teaming relationships (i.e.\, supervisory\, peer-based)\, and individual differences. The algorithm has also been demonstrated to detect shifts in workload in real-time in order to adapt the robot’s interaction with the human and autonomously change task responsibilities when the human’s workload is over- or underloaded. Recently\, the algorithm was used to post-hoc analyze the resulting workload for a single human deploying a heterogeneous robot swarm in an urban environment. Current efforts are focusing on predicting the human’s future workload\, recognizing the human’s current tasks\, and estimating workload for previously unseen tasks.

In some\, faster spread is desirable\, in others containing the spread is critically important. We focus on understanding the spatio-temporal spread of epidemics over contact networks with the goal of facilitating or containing the spread as the case may be. In this study\, we choose specific systems as exemplars of instances where the spread is desirable (e.g.\, Vehicle-to-Everything; V2X) and others where the spread is harmful (e.g.\, spread of infectious diseases). \nIn transportation systems\, vehicles are expected to exchange messages with each other and with bikers\, pedestrians\, wheelchairs (Vehicle-to-Vehicle; V2V) and with signaling infrastructure on the roadways (Infrastructure-to-Vehicle; I2V) (together\, V2X). We seek to qualitatively understand and subsequently quantitatively model the impact of complex\, various interdependencies between wireless communication (spread of information through evolving links) and vehicular mobility (spatial movements of nodes). Towards this end\, we introduce epidemiological modeling into transportation systems\, a novel concept geared towards V2X\, in which the computations remain tractable even for large\, complex transportation networks. We additionally accommodate arbitrary traffic synchronization patterns corresponding for example to the presence of an arbitrary number of traffic signals. Furthermore\, numerical computations using our mathematical framework reveal several questions that influence the practice of V2X network design and security. \nNext\, suppressing spread of infectious diseases is clearly of critical importance. Recently COVID-19 pandemic has wrecked havoc on lives and livelihoods worldwide. We explore the costs and benefits of a new tracing and testing concept towards containing COVID-19. We propose to preemptively identify the contact chain by testing primary\, secondary\, tertiary or further-off contacts of those who test positive\, more specifically\, the k-hop contacts for a parameter k of choice. We evaluate the costs and benefits of this novel multi-hop testing strategy for various reported disease parameters and on diverse human contact patterns\, and see if the cost-benefit tradeoffs may be substantially enhanced through the deployment of the strategy. Furthermore\, we propose an analytical methodology for evaluating multi-hop contact tracing strategy by combining the multi-hop contact tracing dynamics and the virus transmission mechanism in a single framework using microscopic Markov Chain approach.

One of the major developments lies in the incorporation of multiple microfluidic devices onto single chips enabling emulsion generation at clinical and industrial-relevant scale. However\, most demonstrated successes have focused on producing simple emulsions; production upscaling of complex emulsion and materials have not been realized. In this thesis\, I will demonstrate new approaches and some early successes to fill this gap between lab-scale and industrially relevant scale production of complex emulsion and drop-based on-chip material synthesis. First\, a silicon-and-glass based microchip is developed for ultrahigh throughput on-chip photopolymerization of microgels. We demonstrate that the mechanical properties of microgels can be modulated by tuning the UV dosage and a massive parallelization of 4080 microfluidic synthesis lines on a 4-inch wafer. Second\, a new wettability patterning strategy\, along with the fabrication process\, is developed to pattern the hydrophobicity of a silicon-based microfluidic chip. We demonstrate wettability patterning with micrometer resolution and generation of both W/O/W and O/W/O double emulsions. Further\, the scalability of this approach is demonstrated with chips that incorporate 50 parallelized double-emulsion generating devices\, producing double emulsions in a high throughput manner (26.5 kHz double emulsions). Lastly\, we extend the above approach and develop a novel approach to perform surface wettability patterning via polymer enrichment and replica molding (SUPER)\, controlling the wettability of microfluidic channels made of a solvent-resistant PFPE-PEG copolymer network. We demonstrate the utility of this approach by fabricating a PFPE-PEG based microfluidic chip\, with hydrophobic/hydrophilic patterned microchannels\, to generate double emulsions.
