Collective Motility, Mechanical Waves, and Durotaxis in Cell Clusters
Youyuan Deng, Herbert Levine, Xiaoming Mao +1
Epithelial cell clusters often move collectively on a substrate. Mechanical signals play a major role in organizing this behavior. There are a number of experimental observations i…
Random Walker Models for Durotaxis
Charles R. Doering, Xiaoming Mao, Leonard M. Sander
Motile biological cells in tissue often display the phenomenon of durotaxis, i.e. they tend to move towards stiffer parts of substrate tissue. The mechanism for this behavior is no…
Fiber networks below the isostatic point: fracture without stress concentration
Leyou Zhang, D. Zeb Rocklin, Leonard M. Sander +1
Crack nucleation is a ubiquitous phenomena during materials failure, because stress focuses on crack tips. It is known that exceptions to this general rule arise in the limit of st…
Noise induces rare events in granular media
Evgeniy Khain, Leonard M. Sander
The granular Leidenfrost effect (B. Meerson et al, Phys. Rev. Lett. {\bf 91}, 024301 (2003), P. Eshuis et al, Phys. Rev. Lett. {\bf 95}, 258001 (2005)) is the levitation of a mass…
Memory Recall and Spike Frequency Adaptation
James P. Roach, Leonard M Sander, Michal R. Zochowski
The brain can reproduce memories from partial data; this ability is critical for memory recall. The process of memory recall has been studied using auto-associative networks such a…
Nonlinear elasticity of disordered fiber networks
Jingchen Feng, Herbert Levine, Xiaoming Mao +1
Disordered biopolymer gels have striking mechanical properties including strong nonlinearities. In the case of athermal gels (such as collagen-I) the nonlinearity has long been ass…
