The fluctuations of the steps can be viewed as a form of Brownian motion (viz.
random motion of a heavy entity due to thermal fluctuations of light particles) and
can be analyzed using a capillary-wave approach and Langevin formalism. ...

Fractal boundaries are considered as appropriate models to mimic the
geometrical irregularity in realistic systems. We wish to ... Starting from a random
point located in the interfacial region, an off-lattice diffusive Brownian dynamics
simulation is performed to compute the first passage statistics. ... These
relationships can be understood if we considered the integrated probability Po(t)
that a random walk launched at t=0 in the bulk hits the boundary interface for the
first time in time t.

Brownian and Langevin simulations of ions in solution require the maintenance
of average fixed concentrations at the interface between the simulation volume
and the surrounding continuum. This requires ... fluctuation, because the
stochastic dynamics of ions in solution are nonlinear, due to the coupling
between the electrostatic field and the motion of the mobile charges, so that
averaged boundary conditions do not reproduce correctly averaged nonlinear
response. However, in a ...

SIMULATION DEVELOPMENT Our approach has been to formulate the nonlocal
rheology starting with a many-bead/rod model for a polymer which includes intra-
and interpolymer interactions including excluded volume, hydrodynamic,
Brownian and connectivity forces. With this formulation we then proceed with full
Brownian dynamic simulations of dilute and semi-dilute polymer solutions near
interfaces. We focus on the dynamics of tethered or grafted chain layers (as a
particularly ...
