Noise-induced temporal dynamics in Turing systems.

摘要: We examine the ability of intrinsic noise to produce complex temporal dynamics in Turing pattern formation systems, with particular emphasis on Schnakenberg kinetics. Using power spectral methods, we characterize behavior system using stochastic simulations at a wide range points parameter space and compare analytical approximations. Specifically, investigate whether polarity switching patterns occurs defined frequency. find that it can do so individual realizations simulation, but frequency is not consistently across our samples space. Further, effect deterministically predicted traveling waves them increased amplitude decreased speed.
