Spontaneous Activity Induced by Gaussian Noise in the Network‐Organized FitzHugh‐Nagumo Model

Q Zheng, J Shen, Y Xu - Neural Plasticity, 2020 - Wiley Online Library
In this paper, we show some dynamical and biological mechanisms of the short‐term
memory (the fixed point attractor) through the toggle switch in the FitzHugh‐Nagumo model …

Stochastic resonance in genetic regulatory networks under Lévy noise

Y Ding, J Shen, J Lu, J Kurths - Europhysics Letters, 2019 - iopscience.iop.org
It is well known that noise plays an important role in genetic regulatory networks. It can not
only affect the overall characteristics of the genetic regulatory networks, but also produce …

Turing instability in a gene network with cross-diffusion

Q Zheng, J Shen - Nonlinear Dynamics, 2014 - Springer
In this paper, we consider the process of pattern formation induced by nonlinear diffusion in
the gene network with cross-diffusion. We present a theoretical analysis of the pattern …

Hopf bifurcation analysis of a gene regulatory network mediated by small noncoding RNA with time delays and diffusion

C Li, H Liu, T Zhang, F Yan - International Journal of Bifurcation and …, 2017 - World Scientific
In this paper, a gene regulatory network mediated by small noncoding RNA involving two
time delays and diffusion under the Neumann boundary conditions is studied. Choosing the …

Turing Bifurcation and Pattern Formation of Stochastic Reaction‐Diffusion System

Q Zheng, Z Wang, J Shen… - Advances in Mathematical …, 2017 - Wiley Online Library
Noise is ubiquitous in a system and can induce some spontaneous pattern formations on a
spatially homogeneous domain. In comparison to the Reaction‐Diffusion System (RDS) …
