Effective Temperature in Stochastic Kinetics and Gene Networks

@article{citeulike:733336, abstract = {The fluctuation-dissipation theorem, one of the central theorems in thermal dynamics, breaks down in out-of-equilibrium systems.

To develop this idea, we study a simple birth-death process and a general two-species interacting process using the language of effective temperature.
