We have used Monte Carlo simulation and the Gibbs–Duhem integration technique to calculate temperature– composition and pressure–temperature phase diagrams for binary Lennard–Jones mixtures. We systematically explore Lennard–Jones parameter space to demonstrate how the features of these phase diagrams change as a function of diameter ratio, well-depth ratio, binary interaction parameter, and pr...

A system of non-linear di€erence equations is used to model the e€ects of density-dependent selection and migration in a population characterized by two alleles at a single gene locus. Results for the existence and stability of polymorphic equilibria are established. Properties for a genetically important class of equilibria associated with complete dominance in ®tness are described. The birth ...

Running title: Analysis of a discrete one-island migration model Abstract. A system of nonlinear diierence equations is used to model the eeects of density-dependent selection and migration in a population characterized by two alleles at a single gene locus. Results for the existence and stability of polymorphic equilibria are established. Properties for a genetically important class of equilib...

We consider equilibrium solutions of the Smoluchowski equation for rodlike nematic polymers with a Maier–Saupe excluded volume potential. The purpose of this paper is to present a new and simplified proof of classical well-known results: (1) all equilibria are axisymmetric and (2) modulo rotational symmetry, the number and type of axisymmetric equilibria are characterized with respect to the st...
