I will present a general approach for constructing a Markov process that describes the dynamics of a process when one or more observables of this process are observed to fluctuate in time away from their typical values. This will extend some well...

For linear transport equation with diffusive scaling, classical diffusion may fail when the diffusion matrix becomes unbounded, which can be attributed to two reasons. One comes from the heavy tail equilibrium and the other is due to the degenerate...

We present an algorithm for coupling inexpensive low-fidelity model simulations with high-fidelity simulation data of parameterized differential equations. The goal is to grab a "free lunch": simulation accuracy of the high-fidelity model with...

The idea of this event is to offer graduate students in Statistics and Actuarial Science with an opportunity to attend a seminar with accessible talks providing them an introduction to active areas of research in the field. For three students from...

Mechanical properties of materials are usually determined by defects, their evolution and interaction. Therefore, the key to design new and better materials than those available nowadays relies on understanding, controlling, and ultimately...

We prove two related concentration inequalities concerning the points of elliptic curves contained within subsets of F_p^2. In particular we investigate the probability of a large difference between the portions of quadratic residues and non-residues...

I will present an overview of various results on dynamics and equilibria of a simple first-order aggregation model. In spite of its simplicity, there is rich mathematics and a variety of issues that can be investigated for this model.

The Cahn-Hilliard equation models the motion of interfaces between several phases. The underlying energy functional includes a potential for which different types were proposed in the literature. We consider smooth and nonsmooth potentials with a...

What do toothpaste, paint and glaciers have in common? All three fluids usually behave like a plastic solid, but as soon as the stress exceeds a critical threshold, they suddenly begin to flow like a viscous liquid. Rheologists refer to such...
