Abstract: The Hemibrain is the largest published connectome to date. It is the result of a dense reconstruction of over twenty thousand neurons and ten million synapses spanning the fruit fly Drosophila central brain. I will describe a novel approach to uncovering the hierarchical community structure of this connectome. This approach allows us to recover […]

Time: 2pm – 3pm, 9/23/2022 Location: Zoom https://us02web.zoom.us/j/85199919254?pwd=Um9oZkVFZVIyMjVXL3M5T2poNEZsUT09 Title: Coupled cell hypernetworks for identical cells and synchrony Abstract: Coupled cell hypernetworks are introduced. These correspond to a new class of coupled cell networks whose structure is determined by a directed hypergraph, capturing the fact that the evolution of each cell depends (typically nonlinearly) on an interaction involving […]

Time: 9:30 – 10:30am Location: SB147 and Zoom Title: Age- and Size-Structured Deterministic Models with Applications to Biological Sciences and Environmental Economics Abstract: Age- and size-dependent models are presented to address important current issues in biological and economic-environmental sciences. The considered deterministic models are described by differential and integral equations. The emphasis will be made […]

Abstract The study of the synergetic effects of multiple interacting disturbances on the dynamical behavior of a biological system has received extensive attention. However, the interactions among disturbances are highly complex and the impacts are not well understood. In this talk, I will discuss the development of mathematical models to study the effects of exogenous pressures on the dynamics […]

Abstract We develop parameter-robust numerical algorithms for Biot modeland apply the algorithms in brain edema simulations. By introducing an intermediate variable, we derive a multiphysics reformulation of the Biot model. Based on the reformulation, the Biot model is viewed as a generalized Stokes subproblem combining with a reaction-diffusion subproblem. Solving the two subproblems together or […]
