Synchronization of coupled stochastic oscillators: The effect of topology
We study sets of genetic networks having stochastic oscillatory dynamics. Depending on the coupling topology we find regimes of

The effect of finite response–time in coupled dynamical systems
Garima Saxena Awadhesh Prasad Ram Ramaswamy
The paper investigates synchronization in unidirectionally coupled dynamical systems wherein the influence of drive on response is cumulative: coupling signals are integrated over a time interval 𝜏. A major consequence of integrative coupling is that the onset of the generalized and phase synchronization occurs at higher coupling compared to the instantaneous $(\tau = 0)$ case. The critical coupling strength at which synchronization sets in is found to increase with 𝜏. The systems explored are the chaotic Rössler and limit cycle (the Landau–Stuart model) oscillators. For coupled Rössler oscillators the region of generalized synchrony in the phase space is intercepted by an asynchronous region which corresponds to anomalous generalized synchronization.
