Abstract content: Qiyi Zhou ~ June 9, 2009 
Dynamics of Elastic Filaments in Stokes Flow: Suspensions of filaments in the Stokes flow regime have a wide range of applications from fiber processing to nanocargo transport systems. In this talk a slenderbody formulation for multiple filaments immersed in Stokes flow will be presented. Analysis and numerical simulation results will show how the dynamics of semiflexible filaments could lead to nontrivial filament transport. Effects of hydrodynamic interactions will be quantified in terms of filament separation, filament flexibility, and slenderness. Finally a brief summary on recent attempts to efficiently model multifilament flows will be presented. This work is an ongoing collaboration with Mike Shelley (Courant Institute, New York University): Yuan N. Young ~ June 11, 2009

Mathematical Models of Combustion: In this talk I will give an introduction into the various classes of mathematical models that are used to investigate combustion systems. Starting with a full set of equations governing chemically reacting flows, I will demonstrate how asymptotic methods are used to extract simpler models. These reduced models retain the essential physics of the combustion process, but their simplicity makes them amenable to analysis. I will also briefly describe how these models can be used to investigate problems of current interest, such as the phenomena of selfwrinkling and selfstabilizing flames. John K.

Intracellular Calcium Diffusion and Synaptic Neurotransmitter Release: Calcium plays an important signaling role in a variety of crucial physiological processes, from gene transcription to muscle contraction. Notably, calcium is also indispensable for the functioning of the nervous system, where calcium ion influx into the synapse triggers the release of neurotransmitter, enabling the transmission of electric activity between two synaptically coupled neurons. Since the resting concentration of calcium is very low inside a cell, the influx of calcium through calcium channels is very localized. This localization of calcium action is further insured by various molecular substances that bind calcium, termed calcium buffers. Thus, understanding the spatiotemporal characteristics of calcium signaling requires mathematical modeling of calcium diffusion and buffering. In this talk I will review the basics of synaptic transmission and calcium regulation inside neural (and other) cells, and will provide a basic analysis of the partial differential equations that describe buffered calcium diffusion.
