(p,q)-string in matrix-regularized membrane and type IIB duality
We consider a lightcone wrapped supermembrane compactified on 2-torus in the
matrix regularization. We examine the double dimensional reduction technique
and deduce the free matrix string of (p,q)-string in type IIB superstring
theory explicitly from the matrix-regularized wrapped supermembrane. In
addition we obtain the (2+1)-dimensional super Yang-Mills action in curved
background. We also examine the duality.Comment: 25 page

The rheology of a dilute suspension of Brownian dipolar spheroids in a simple shear flow under the action of an external force
The effect of rotational Brownian motion on the rheology of a dilute suspension of dipolar spheroids
in a simple shear flow under the action of an external force field, is investigated through a
generalized Langevin equation approach. The force field is assumed to be either constant or
periodic. In the case of constant external fields earlier results in the literature are reproduced, while for the case of periodic forcing certain parametric regimes corresponding to weak Brownian diffusion are identified where the rheological parameters evolve chaotically and settle onto a low dimensional attractor. The response of the system to variations in the strengths of the force field and diffusion is also analyzed through numerical experiments. These results correspond to the region of
weak Brownian motion where usual methods render the problem intractable
