Recombination dramatically speeds up evolution of finite populations
Elisheva Cohen, David A. Kessler, Herbert Levine
We study the role of recombination, as practiced by genetically-competent bacteria, in speeding up Darwinian evolution. This is done by adding a new process to a previously-studied…
Crack (Non)Propagation in Amorphous Media
Tsviki Y. Hirsh, David A. Kessler
We study Mode I crack propagation in amorphous material via a molecular dynamics simulation of a binary alloy with pairwise central-force interactions. We find that when the system…
Fluctuation-regularized Front Propagation Dynamics
Elisheva Cohen, David A. Kessler, Herbert Levine
We introduce and study a new class of fronts in finite particle number reaction-diffusion systems, corresponding to propagating up a reaction rate gradient. We show that these syst…
Velocity Fluctuations in Dynamical Fracture: the Role of Microcracks
E. Bouchbinder, D. Kessler, I. Procaccia
We address the velocity fluctuations of fastly moving cracks in stressed materials. One possible mechanism for such fluctuations is the interaction of the main crack with micro cra…
