The locomotion of most fish and birds is realized by flapping wings or fins transverse to the direction of travel. Here, we study experimentally the dynamics of a wing that is flapped up and down but is free to move in the horizontal direction. In this table-top prototype experiment, we show that flapping flight occurs abruptly at a critical fla...

The goal of this lecture is to inform the audience of the types of challenges that arise, and open problems that remain, in a specific class of biological fluids: mucus. Mucus is prevalent in biology and its rheology is fundamental for: locomotion (e.g., of snails); flow transport (e.g., of mucosal layers in mammalian lungs); and controlling dif...

Integro-differential equations arise naturally in the study of stochastic processes with jumps. These types of processes are of particular interest in finance, physics and ecology. In the talk, we study uniqueness, existence and regularity of solutions of integro-PDE in domains of R^n.

A uniqueness result for the recovery of the electric and magnetic coefficients in the time-harmonic Maxwell equations from local boundary measurements is shown. No special geometrical condition are imposed on the inaccessible part of the boundary of the domain, apart from that that the boundary of the domain is C1,1. The coefficients are assumed...

Pencil drawing of the Unitarian church building in Geneseo, Illinois, in two-point perspective. Drawn by Francis Lee Jaques at six years old, in 1893 or 1894, "Lee Jaques" appears in large, three-dimensional letters running the length of ground beside the church, as if planted like a flower bed. A newspaper clipping is attached to the lower righ...
