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…

Arrested Cracks in Nonlinear Lattice Models of Brittle Fracture
David A. Kessler, Herbert Levine
We generalize lattice models of brittle fracture to arbitrary nonlinear force laws and study the existence of arrested semi-infinite cracks. Unlike what is seen in the discontinuou…

Steady-State Cracks in Viscoelastic Lattice Models
David A. Kessler, Herbert Levine
We study the steady-state motion of mode III cracks propagating on a lattice exhibiting viscoelastic dynamics. The introduction of a Kelvin viscosity allows for a direct compar…
