Neutral-like abundance distributions in the presence of selection in a continuous fitness landscape
David A. Kessler,Nadav M. Shnerb +1 more
TL;DR: The neutral theory of biodiversity has successfully explained the observed composition of many ecological communities but it relies on strict demographic equivalence among species and provides no room for evolutionary processes such as selection and adaptation.
Journal ArticleDOI
Does the continuum theory of dynamic fracture work
David A. Kessler,Herbert Levine +1 more
TL;DR: This work investigates the validity of the linear elastic fracture mechanics approach to dynamic fracture, and first test the predictions in a lattice simulation, using a formula of Eshelby for the time-dependent stress intensity factor.
Journal ArticleDOI
Coexistence of symmetric and parity-broken dendrites in a channel
TL;DR: In this article, the steady state equation and the stability spectrum for solidification in a channel were numerically solved for a large range of parameters and stable symmetric and parity-broken solutions coexist.

Selection of the Viscous Finger in the 90° Geometry
Abstract: The theory of solvability is applied to the Saffman-Taylor experiment in the 90? geometry. We find that in the limit of zero surface tension the parameter ? which governs the width of the finger approaches 0.85 which agrees very well with the experimentally observed value. We also discuss the scaling of the parameter ?.
