I reexamine the use of isolation by distance models as a basis for the estimation of demographic parameters from measures of population subdivision. To that aim, I first provide results for values ofâ€¦ (More)

This paper reviews and discusses what is known about the relationship between identity in state, allele frequency, inbreeding coefficients, and identity by descent in various uses of these terms.â€¦ (More)

The population genetic structure of Plasmodium falciparum, the agent of malignant malaria, has been shown to be predominantly "clonal" (i.e., highly inbred) in regions of low infectivity; inâ€¦ (More)

We prove an abstract instability result for an eigenvalue problem with parameter. We apply this criterion to show the transverse linear instability of solitary waves on various examples fromâ€¦ (More)

CD40 is a 45- to 50-kilodalton transmembrane glycoprotein expressed on B lymphocytes, epithelial cells, and some carcinoma cell lines. Human resting B lymphocytes entered a state of sustainedâ€¦ (More)

Abstract We justify rigorously the convergence of the amplitude of solutions of Nonlinear-SchrÃ¶dinger type Equations with non zero limit at infinity to an asymptotic regime governed by the Kortewegdeâ€¦ (More)

The orbital stability of possibly large semi-discrete shock waves is considered. These waves are traveling wave solutions of discrete in space and continuous in time systems of conservation laws,â€¦ (More)

We consider the Vlasov-HMF (Hamiltonian Mean-Field) model. We consider solutions starting in a small Sobolev neighborhood of a spatially homogeneous state satisfying a linearized stability criterionâ€¦ (More)

We consider an initial boundary value problem for a symmetrizable mixed hyperbolic-parabolic system of conservation laws with a small viscosity Îµ, ut +F (u )x = Îµ(B(u)ux)x. When the boundary isâ€¦ (More)
