Physical Review Letters 2004年 第19期93卷 198106-198106页
作者: Todd M. Squires Department of Physics and Department of Applied and Computational Mathematics California Institute of Technology 114-36 Pasadena California 91125 USA
The fluid-filled semicircular canals (SCCs) of the vestibular system are used by all vertebrates to sense angular rotation. Despite masses spanning seven decades, all mammalian SCCs are nearly the same size. We propos... 详细信息

Physical Review Letters 2004年 第9期93卷 098103-098103页
作者: Christopher Dombrowski Luis Cisneros Sunita Chatkaew Raymond E. Goldstein John O. Kessler Department of Physics University of Arizona Tucson Arizona 85721 USA Program in Applied Mathematics University of Arizona Tucson Arizona 85721 USA
Suspensions of aerobic bacteria often develop flows from the interplay of chemotaxis and buoyancy. We find in sessile drops that flows related to those in the Boycott effect of sedimentation carry bioconvective plumes... 详细信息
