    We have examined the recently proposed concept of self-guiding in the context of both stochastic and deterministic dynamics of a test particle in a double-well potential. In contrast to the original suggestion, results from our stochastic dynamics simulations indicate that enhancement of the...

    We introduce a dissipative particle dynamics scheme for the dynamics of nonideal fluids. Given a free-energy density that determines the thermodynamics of the system, we derive consistent conservative forces. The use of these effective, density dependent forces reduces the local structure as...
