SUMMARY:MEAM Seminar: "Dynamical Systems Approach to Geophysical and Aerospace Flows"
DESCRIPTION:A dynamical systems approach is taken to explain the dynamics of two classes of ‘gap-leaping’ geophysical flow as well as the hypersonic second-mode instability. First\, in the context of a loop current system\, it is shown that multiple steady flow patterns with hysteresis exist and appear to satisfy a cusp catastrophe geometry of solutions. Which state the system assumes (looping or leaping or periodic eddy shedding) and when transitions between states occur\, will be discussed in terms of fundamental vorticity advection and dissipation. Second\, a global perspective of Gulf of Maine circulation leads to a new mechanism for Scotian Shelf Water crossover events. Finally\, by considering an idealized system and an analogy with harmonic oscillators\, a fundamental mechanism for the hypersonic second-mode instability is proposed.

SUMMARY:CBE Seminar: "Complexity in the Chemistry and Physics of Lipid Membranes as a Handle to Activate the Delivery of Cargo to Cells”
DESCRIPTION:Abstract: \nLipid materials having nanostructures that deviate from the conventional flat bilayer arrangement such as hexagonally packed lipid tubes and bi-continuous cubic phases are ubiquitous in nature. Their role remains elusive but over the years several pathologies and organelle functions have been coupled to lipid membrane structural complexity. In this talk\, we will discuss lipid membrane polymorphism and how it can be exploited to generate a new class of materials for the delivery of cargo to cells. We combine a number of techniques including X-ray scattering\, cryo-EM\, and cell culture to demonstrate that the structure of lipid nanoparticles is a powerful handle to boost the delivery of genes to cells. The simple argument that non-lamellar phases having intertwined nanoscale channels exist to increase surface-to-volume ratio might be insufficient to completely describe the experimental findings. \nIf there is time\, we will also introduce the concept of soft-material alloys. Lipids and polymers can mix in hybrid membranes having synergistic dynamical and structural properties; many of which are seen in lipid-protein membrane systems in nature

SUMMARY:PRiML Seminar: "Building Algorithms by Playing Games"
DESCRIPTION:A very popular trick for solving certain types of optimization problems is this: write your objective as the solution of a two-player zero-sum game\, endow both players with an appropriate learning algorithm\, watch how the opponents compete\, and extract an (approximate) solution from the actions/decisions taken by the players throughout the process. This approach is very generic and provides a natural template to produce new and interesting algorithms. I will describe this framework and show how it applies in several scenarios\, and describe recent work that draws a connection to the Frank-Wolfe algorithm and Nesterov’s Accelerated Gradient Descent.
