Mathematical Modeling of Energy Consumption in the Acute Inflammatory Response

Abstract:

When a pathogen enters the human body, an acute inflammatory response is activated to eliminate the intruder. However, in some patients an extreme response of the immune system may occur which can lead to tissue damage, organ failure, and eventually death. This overwhelming reaction of the immune system is called sepsis.

Unirationality of Low Degree Hypersurfaces

Abstract:

There are several notions which define classes of projective varieties which are close to projective space: unirationality, rationality, stable rationality, etc.  I will discuss what is known about some of these notions for hypersurfaces. The focus of my talk will be on unirationality of hypersurfaces and how spaces of linear subvarieties can be used to show low degree hypersurfaces are unirational.

This is based on joint work with Eric Riedl.
