Recent theoretical research by Kornhauser and Revesz finds that joint and several l iab i l i ty may either encourage or discourag...

We provide a selective review of recent progress in the analysis of several physiological and physiologically inspired fluid-structure interaction problems, our aimbeing to explain the underlying physicalmechanisms that cause the observed behaviors. Specifically, we discuss recent studies of self-excited oscillations in collapsible tubes, focusing primarily on studies of an idealized model syst...
