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…
Alignment and Nonlinear Elasticity in Biopolymer Gels
Jingchen Feng, Herbert Levine, Xiaoming Mao +1
We present a Landau type theory for the non-linear elasticity of biopolymer gels with a part of the order parameter describing induced nematic order of fibers in the gel. We attrib…
Non-native beta-sheet formation: insights into protein amyloidosis
Chinlin Guo, Herbert Levine, David A. Kessler
Protein amyloidosis is a cytopathological process characterized by the formation of highly beta-sheet-rich fibrils. How this process occurs and how to prevent/treat the associated…
Phase-Field Model of Mode III Dynamic Fracture
Alain Karma, David A. Kessler, Herbert Levine
We introduce a phenomenological continuum model for mode III dynamic fracture that is based on the phase-field methodology used extensively to model interfacial pattern formation.…
Mechanisms underlying sequence-independent beta-sheet formation
Chinlin Guo, Herbert Levine, Margaret S. Cheung +1
We investigate the formation of beta-sheet structures in proteins without taking into account specific sequence-dependent hydrophobic interactions. To accomplish this, we introduce…
Self-organization in systems of self-propelled particles
Herbert Levine, Wouter-Jan Rappel, Inon Cohen
We investigate a discrete model consisting of self-propelled particles that obey simple interaction rules. We show that this model can self-organize and exhibit coherent localized…
Two State Behavior in a Solvable Model of -hairpin folding
Chinlin Guo, Herbert Levine, David Kessler
Understanding the mechanism of protein secondary structure formation is an essential part of protein-folding puzzle. Here we describe a simple model for the formation of the -ha…
Interfacial Velocity Corrections due to Multiplicative Noise
Leonid Pechenik, Herbert Levine
The problem of velocity selection for reaction fronts has been intensively investigated, leading to the successful marginal stability approach for propagation into an unstable stat…
