Neuroendocrine stress response and PTSDThe hypothalamic-pituitary-adrenal (HPA) axis is a neuroendocrine system that regulates numerous physiological processes. Disruptions are correlated with stress-related diseases such as PTSD and major

A touch of non-linearity in fluid fields: where spheres “think” collectively and swim togetherFrom crawling cells to orca whales, swimming in nature occurs at different scales. The study of swimming across length scales can shed light onto

Title:  "Efficient representation of high-order finite element operators"Abstract: We present an extensible low-level library that provides a versatile algebraic interface and optimized implementations suitable for high-order operators: libCEED

Dynamics of Nonlinear Random Walks on Complex NetworksRandom walks serve as an important tool in the complex networks community due to widespread applications including Google’ PageRank algorithm, community detection, network exploration, and

Private AI (or: How to Keep Your Location Data Secret)As the world rushes towards the adoption of Artificial Intelligence (AI) in all aspects of our lives, the promise is great, but the risks are many. AI can help to improve and simplify our daily

Topologically Protected Edge Modes in Longitudinally Driven Waveguides  A tight-binding approximation is developed for deep longitudinally driven photonic lattices. The physical system considered is that of a laser-etched waveguide array

Stars are filled with sound. Turbulent convection within a star makes a broadband hum, but certain frequencies get amplified because they are resonant. For example, the Sun’s surface throbs and rings under the combined influence of several million

Practical and Theoretical Questions in Network Synchronization: Optimization and Control Collective behavior in large ensembles of network-coupled dynamical systems remains an active area of research in the nonlinear dynamics and networks

Suspensions of active particles in fluids exhibit incredibly rich behavior, from organization on length scales much longer than the individual particle size to mixing flows and negative viscosities. We will discuss the dynamics of hydrodynamically

Osman Malik - Fast Randomized Matrix and Tensor Interpolative Decomposition Using CountSketchIn this talk I will present our recently developed fast randomized algorithm for matrix interpolative decomposition. If time permits, I will also say a few
