Query: The Fluctuation Theorem for Stochastic Systems   The Fluctuation Theorem describes the probability ratio of observing
trajectories that satisfy or violate the second law of thermodynamics. It has
been proved in a number of different ways for thermostatted deterministic
nonequilibrium systems. In the present paper we show that the Fluctuation
Theorem is also valid for a class of stochastic nonequilibrium systems. The
Theorem is therefore not reliant on the reversibility or the determinism of the
underlying dynamics. Numerical tests verify the theoretical result.
