Figure 6From: Time delay induced transition of gene switch and stochastic resonance in a genetic transcriptional regulatory model< x > st and MFPT are plotted as a function of delay time τ 1 with α = 0.01, D = 0.015 and λ = 0.3. The other parameter values are the same as those in Figure 2. The red sold line represents the theoretical results, and the blue dot line represents the numerical simulation results.
