Talk Title: Role of Arterial Stiffness and Pulsatile Hemodynamics in Target Organ Damage: Implications for Human Health
Abstract: The normal aorta exerts a powerful cushioning function, which limits arterial pulsatility and protects the microvasculature from excessive fluctuations in pressure and blood flow. Large-artery stiffening, which occurs with aging and various pathologic states, impairs this cushioning function, and has important consequences on target organs, including the brain, the heart, the kidneys and the placenta. Arterial stiffness also appears to be implicated in the pathogenesis of cardiometabolic disease. Large-artery stiffness represents a high-priority therapeutic target to ameliorate the global burden of cardiovascular disease in the next several decades. We will discuss key physiologic and biophysical principles related to arterial stiffness and the impact of aortic stiffening on target organs and associated disease states.

Talk Title: Do we really need all that data? Learning and control for contact-rich manipulation
Abstract: For all the promise of big-data machine learning, what will happen when robots deploy to our homes and workplaces and inevitably encounter new objects, new tasks, and new environments? If a solution to every problem cannot be pre-trained, then robots will need to adapt to this novelty. Can a robot, instead, spend a few seconds to a few minutes gathering information and then accomplish a complex task? Why does it seem that so much data is required, anyway? I will first argue that the hybrid or contact-driven aspects of manipulation clashes with the inductive biases inherent in standard learning methods, driving this current need for large data. I will then show how contact-inspired implicit learning, embedding convex optimization, can reshape the loss landscape and enable more accurate training, better generalization, and ultimately data efficiency. Finally, I will present our latest results on how these learned models can be deployed via real-time multi-contact MPC for dexterous robotic manipulation, where the robot must autonomously make and break contact and initiate stick-slip transitions.

Speaker: Jasna Brujic, NYU
Talk Title: Colloidal protein analogs
Abstract: Our group is inspired by Nature’s strategy of folding biopolymers into specific protein and RNA structures to build a toy model of polymeric chains of droplets, i.e. “colloidomers”, that are designed via DNA interactions to fold into well-defined architectures. Indeed, simple alternating chains (up to 14 droplets long) with only two droplet flavors (ABABAB…) are sufficient to uniquely encode a dozen “foldamers”, constituting 1% of all possible rigid structures in 2D. Subsequently, these 2D foldamers can self-assemble into larger nets that, upon density-matching, are able to further fold into unique 3D geometries, for example viral capsids. These hierarchical protocols circumvent the vast phase space of the nominal folding landscape, in which a random cluster of 12 particles has tens of thousands or rigid folds to choose from. Once the colloidal protein analog is formed, it can then be further programmed by the polymerase-exonuclease-nickase (PEN) toolbox of enzymes that interact with droplet-droplet DNA bonds, to produce highly non-linear dynamical systems. These "mayonnaise robots” promise to offer a bright and functional future on the colloidal length scale.

Talk Title: The Effect of Reef Geometry On Breaking Wave Shape. Computational and Field Data Comparative Study
Abstract: With growing demand for inland surfing and interest in artificial surf reefs, CFD methods supplemented with field data constitute an effective tool that allows for analysis, optimization, and verification of the design performance of surfing waves. Bringing surfing to non-coastal areas provides big opportunities for a new market. This led to the formation of a new sub-genre of hydrodynamics engineering, where one is looking at transformation of shallow-water waves through a slightly different lens. In classical coastal engineering, wave characteristics can affect various design conditions of certain structures – however, in the following case, one is looking specifically into analysis, optimization, and verification of design performance of the surf-zone wave itself, i.e. its surfability aspect. This presentation provides a high-level overview of the scientific process behind the creation of the Kelly Slater Wave Company basin in Lemoore, CA. Some details of the new and much larger wave basin opening in Abu Dhabi, where excess energy from the main wave is reformed and broken again providing a secondary surfing experience will also be discussed.
