The presence of the magnetic stochasticity induced by resonant magnetic perturbations in fusion experiments leads to radial electron particle and heat diffusivities which are substantially different from quasilinear predictions. In this paper, using neoclassical simulation, the effects of the self-consistent electric field on the radial electron particle and heat transports are investigated. The presence of stochasticity produces positive contribution to the radial electric field, consistent with experimental observations. Bringing both radial and poloidal components of the electric field into the simulation might help recover some of the trends observed in the experiment and is currently under investigation.

    An iterative transfer perturbation method is proposed to treat the interaction between a polymer and a small molecule at the level of the ab initio method. The validity of our method is examined by applying it to a simple model system and comparing the results with those from the conventional...
