We study the evolution of fronts in a bistable equation with time-delayed global feedback in the fast reaction and slow diffusion regime. This equation generalizes the Hodgkin-Grafstein and Allen-Cahn equations. We derive a nonlinear equation governing the motion of fronts, which includes a term with delay. In the one-dimensional case this equation is linear. We study the motion of one- and two...

The Agents of Bioterrorism course (BSBD 640, University of Maryland University College) is a graduate level course created in response to an elevated need for scientists working in the field of medical countermeasures to biological and chemical weapons in the years following 9/11.

With a very long history, traditional Chinese medicine (TCM) has a rich knowledge about human health and disease by its special way. To avoid losing lots of precious knowledge of TCM masters, endeavors have been engaged to keep down those knowledge of TCM masters, such as their growth experiences, effective practical cases toward sickness and typical treating methods and principles. In this pap...
