Frequency domain analysis of a stochastic biological network motif with delay

Abstract

In this paper, a set of delay stochastic differential equations, which involves the mechanisms of intrinsic and extrinsic noises, time delays and negative feedback, is proposed to describe the nonlinear dynamics within a general biological network motif. Frequency domain analysis method is exploited to study the interplays among such mechanisms. © 2009 ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
