Noise and time delay can change the oscillating behaviors of complex systems greatly. Time delay is often classified as propagation time delay and processing delay (intrinsic response), and noise is often associated with uncertainty or stochastic fluctuation. Particularly, noise and time delay are often considered so that the transition of synchronization behaviors, pattern regularity could be detected. It is believed that time delay could be associated with the memory effect and noise often decreases the regularity of dynamical systems. Interestingly, intermediate noise intensity and/or time delay can enhance the spatial regularity of coupled oscillators or network o ...
