In this talk I will discuss the genetic structure of populations subject to climate change and undergoing range expansion. The models and analyses are based on reaction diffusion and integrodifference equations for the asymptotic neutral genetic...

In this paper we present a general framework in which one can rigorously study the effect of spatio-temporal noise on traveling waves, stationary patterns and oscillations that are invariant under the action of a finite-dimensional set of continuous...

The activation of T cells, key players of the immune system, involves local evacuation of molecules (phosphatases) from the nearby region of the cell surface, segregating them from the T cell receptor. What drives this evacuation? This phenomenon...

Humans are affecting the planet in diverse ways. One of those that receives scant attention is the effect that chemicals are having on life. In this talk, I will use data from my lab on a variety of animal models, including invertebrates and...

Consider two finitely generated field extensions K and L of the same transcendence degree over some base field F. Suppose these extensions become isomorphic over F after adjoining some variables. Does this imply that K isalready isomorphic to L over...

We introduce p-adic cellular neural networks, a mathematical generalization of cellular neural networks. These networks have infinite cells with a hierarchy structure and hidden layers. We discuss two types of p-adic CNNs: one for grayscale image...

The workshop is intended to mathematicians who are contest coordinators or who are interested in joining us. The objectives are to share experiences and have discussions on: - organizing training sessions in all participating cities as well as...

Math Mania presents a variety of interactive demonstrations, games and art such as soap bubbles, 'get your goat' (Monty Hall game), the penny game, the Set Game, the 'Game of 24', kaleidoscopes and hexaflexagons, Nim, Tower of Hanoi, the amazing...
