BACKGROUND: During the mating pheromone response in budding yeast, activation of a mitogen-activated protein kinase (MAP kinase) cascade results in well-characterized changes in cytoskeletal organization and gene expression. Spatial reorganization of genes ...
We have studied a model of a complex fluid consisting of particles interacting through a hard-core and short-range attractive potential of both Yukawa and square-well form. Using a hybrid method, including a self-consistent and quite accurate approximation ...
The photophysical properties of the triple-stranded dimetallic helicates [Ln2(LC−2H)3]·H2O (Ln = Nd, Sm, Dy, Yb) are determined in water and D2O solutions, and energy transfer processes are modeled for SmIII. The luminescence of NdIII, SmIII, and YbIII is ...
We first describe the three-dimensional extension of the molecular-dynamics models for granular media simulations. We then discuss the known energy dissipation problem occurring when simulating dense granular media with the usual molecular-dynamics forces ...
Simulations of exact spin dynamics in systems of multiple nuclear spins are limited to relatively small numbers of spins by the large size of the Hamiltonian matrices for dipolar-coupled spin systems. We propose using the translational symmetry of periodic ...
Within the framework of the mode-coupling theory of super-cooled liquids, we investigate new phenomena in colloidal systems on approach to their glass transitions. When the inter-particle potential contains an attractive part, besides the usual repulsive h ...
The violation of mirror symmetry in the weak force provides a powerful tool to study the internal structure of the proton. Experimental results have been obtained that address the role of strange quarks in generating nuclear magnetism. The measurement repo ...

We discuss the situation where attractive and repulsive portions of the interparticle potential both contribute significantly to glass formation. We introduce the square-well potential as prototypical model for this situation, and reject the Baxter model a ...
We discuss D-brane dynamics in orbifold compactifications of type II superstring theory. We compute the interaction potential between two D-branes moving with constant velocities and give a field theory interpretation of it in the large distance limit. ...
