Convective storms are highly intermittent and intense, making their occurrence and strength difficult to predict. This is especially true for climate models, which have grid resolutions much coarser (e.g., 100 km) than the scale of a storm’s...

Monitoring marked individuals is a common strategy in studies of wild animals (referred to as mark-recapture or capture-recapture experiments) and hard to track human populations (referred to as multi-list methods or multiple-systems estimation). A...

An important problem in machine learning and computational statistics is to sample from an intractable target distribution, e.g. to sample or compute functionals (expectations, normalizing constants) of the target distribution. This sampling problem...

We survey questions, conjectures and results, old and new, about the distribution of prime numbers. We concentrate on the existence and distribution of primes in the integer value sets of polynomials having integer coefficients. The talk is directed...

In this talk, we will present a definition of a `double category of relations’, inspired by that of a bicategory of relations’ due to Carboni and Walters. Roughly, a `double category of relations’ is a cartesian equipment whose horizontal bicategory...

Exposure of bacteria to cidal stresses typically select for the emergence of stress-tolerant cells refractory to killing. Stress tolerance has historically been attributed to the regulation of discrete molecular mechanisms, including though not...

It is an interesting (and not entirely obvious) fact that every graph admits an orientation of its edges so that the outdegrees at vertices form a "coloring" (outdegrees of any two adjacent vertices are different). The proper chromatic number $\Vec{...

In this talk, we will discuss the relation between two types of two-dimensional lattice models: on one hand, we will consider the spin models with an O(2)-invariant interaction, such as the famous XY and Villain models. On the other, we study integer...

Synthetic biology has become an important field of science focusing on designing and engineering new biological parts and systems or redesigning existing biological systems for useful purposes. In Synthetic biology's entire history, mathematical...
