Diffusive transport without detailed balance in motile bacteria: does microbiology need statistical physics?
ME Cates - Reports on Progress in Physics, 2012 - iopscience.iop.org
Microbiology is the science of microbes, particularly bacteria. Many bacteria are motile: they
are capable of self-propulsion. Among these, a significant class execute so-called run-and …
