    We present a new coordinate-space model of spherically averaged exchange-hole functions in inhomogeneous systems that depends on local values of the density and its gradient and Laplacian, and also the kinetic energy ...
  • Beekman, Richard A.; Roussel, Marc R.; Wilson, P. J. (American Physical SocietyArts and ScienceDepartment of Chemistry and BiochemistryDepartment of PhysicsUniversity of Lethbridgehttps://doi.org/10.1103/PhysRevA.59.503, 1999)
    We have computed the equilibrium conformations of clusters of up to 100 ions in a spherically symmetric harmonic trap by a simple optimization strategy called seeding in which ions are added or removed from ...
  • Roussel, Marc R.; Wang, Jichang (American Physical SocietyArts and ScienceDepartment of Chemistry and BiochemistryUniversity of Lethbridgehttps://doi.org/10.1103/PhysRevLett.87.188302, 2001)
    In this Letter, we report the observation of a transition from self-replicating behavior to stationary spatial structures induced by concentration-dependent diffusivities in the excitable Gray-Scott medium. Notably, the ...

    Many natural and technological systems have on/off switches. For instance, mitosis can be halted by biochemical switches which act through the phosphorylation state of a complex called mitosis promoting factor. If switching ...

    A previously studied model of prokaryotic transcription [Roussel and Zhu, Bull. Math. Biol. 68 (2006) 1681--1713] is revisited. The first four moments of the distribution of transcription times are obtained analytically ...

    The expression of the TGF-β protein Nodal on the left side of vertebrate embryos is a determining event in the development of internal-organ asymmetry. We present a mathematical model for the control of the expression of ...

    Temporal organization of biological processes requires massively parallel processing on a synchronized time-base. We analyzed time-series data obtained from the bioenergetic oscillatory outputs of Saccharomyces cerevisiae ...
