Delay Adjusted Noise Effect in Coupled Nonlinear Chemical System

The counterintuitive noise effect in nonlinear systems plays an important role in determining the system dynamics near the bifurcation point. In many systems whose information processing is based on the spatiotemporal dynamics, delay in the information transition process is also important. In this work, the effect of delay is investigated in a coupled noisy nonlinear chemical signaling system. Simulation results reveal that the delay in the coupled inter-system communication not only can significantly adjust the inherent oscillatory signal, but also capable of modulating the noise effects and change the performance of the noise induced stochastic resonance phenomenon.
