Journal ArticleDOI
Limit Theorems for Height Fluctuations in a Class of Discrete Space and Time Growth Models
TL;DR: In this article, the authors introduced a class of one-dimensional discrete space-discrete time stochastic growth models described by a height function ht(x) with corner initialization.
Journal ArticleDOI
Percolation on the fitness hypercube and the evolution of reproductive isolation.
TL;DR: It is argued that macroevolution and speciation on "rugged" fitness landscapes proceed according to the properties of the corresponding holey landscapes, which may be related to the patterns of speciation.
Journal ArticleDOI
Diffusion processes in composite porous media and their numerical integration by random walks: Generalized stochastic differential equations with discontinuous coefficients
TL;DR: In this article, a random-walk method for simulating subsurface transport in composite porous media has been proposed, which is based on diffusion theory and the theory of stochastic differential equations.
Journal ArticleDOI
A sharper threshold for bootstrap percolation in two dimensions
TL;DR: In this article, the second term in the expansion is −(log n)−3/2+o(1), and moreover determining it up to a poly(log log n)-factor.
Journal ArticleDOI
Isotopic fractionation by diffusion in groundwater
TL;DR: In this article, the potential for isotopic fractionation during transport in groundwater resulting from minute isotopic effects on aqueous diffusion coefficients was considered, and it was shown that diffusion can result in similar degrees of depletion and enrichment of isotopically heavy solutes during transport of heterogeneous systems with significant diffusion rate.
