In this paper, we calculate the rotational and translational diffusion coefficient for a star-like molecule and the shear viscosity for a dilute suspension of these molecules, starting from the Debye-Brinkman equation. For this type of molecules, the

A recently developed method is used to calculate the main effects of excluded volume on the distribution of ions around a charged central sphere in thermal equilibrium. The authors find significant corrections to the results of the conventional Gouy-

Using a new method of calculating the effects of excluded volume, the authors evaluate the distribution of counterions around a charged sphere in thermal equilibrium. In regions of high concentration a saturation of the ion density is found, which is

We derive an exact expression for the distribution of the area which is enclosed by a closed plane polymer loop in a uniform electric field. We show that for strong fields the distributions is a Gaussian whereas for weak electric fields it has a more

We derive an explicit formula for the rate with which a spherical cell with a large number of receptors in its outer membrane captures ligands which have a non-vanishing excluded volume. These corrections to the Berg-Purcell formula, which neglects e

We suggest a discretization of the Dirac equation based on time symmetry. This iterative scheme is correct to second order in e, the lattice distance in time, and can therefore be considered as an improvement to the master equation suggested implicit

In this paper we study the semi-classical approximation for the distribution of area associated with (i) planar polymer rings constrained to enclose a fixed algebraic area and (ii) planar rings subject to an external electric field and constrained to

The statistical mechanical properties of plane polymer configurations which enclose a fixed area and are subject to an external electric field are investigated. For this purpose an exact expression for the generating functional is obtained and subseq
