Monodisperse domains by proteolytic control of the coarsening instability
(American Physical Society, 2011)The coarsening instability typically disrupts steady-state cluster-size distributions. We show that degradation coupled to the cluster size, such as arising from biological proteolysis, leads to a fixed-point cluster size. ... -
Pulling helices inside bacteria: imperfect helices and rings
(2009-04)We study steady-state configurations of intrinsically-straight elastic filaments constrained within rod-shaped bacteria that have applied forces distributed along their length. Perfect steady-state helices result from axial ... -
Self-organization of the MinE protein ring in subcellular Min oscillations
(2009-07)We model the self-organization of the MinE ring that is observed during subcellular oscillations of the proteins MinD and MinE within the rod-shaped bacterium Escherichia coli. With a steady-state approximation, we can ... -
Subcellular Min Oscillations as a Single-Cell Reporter of the Action of Polycations, Protamine, and Gentamicin on Escherichia coli
(2009-09)No abstract available. -
Steady-state helices of the actin homolog MreB inside bacteria: dynamics without motors
(2007-09)Within individual bacteria, we combine force-dependent polymerization dynamics of individual MreB protofilaments with an elastic model of protofilament bundles buckled into helical configurations. We use variational ... -
Maximally fast coarsening algorithms
(2005-11)We present maximally fast numerical algorithms for conserved coarsening systems that are stable and accurate with a growing natural time step Deltat=At2/3s. We compare the scaling structure obtained from our maximally fast ... -

Role of interfaces in the magnetoresistance of Au/Fe/Au/Fe multilayers
(APS through AIP, 2003-02/01)By using the fully relativistic spin-polarized screened Korringa-Kohn-Rostoker method and the corresponding Kubo-Greenwood equation resistivities and the giant magnetoresistance are evaluated for Fe/Au/Fe/Au spin valves ... -
Growth, structure, electronic, and magnetic properties of MgO/Fe(001) bilayers and Fe/MgO/Fe(001) trilayers

Spin-dependent transport in Fe and Fe/Au multilayers
(APS through AIP, 2005-06/01)In situ resistance measurements of epitaxial Fe layers and Au/Fe bilayers were used to quantify the scattering in giant magnetoresistance (GMR) spin valve structures. The semiclassical Boltzmann transport equation, ... -
Direct observation of spin configurations and classification of switching processes in mesoscopic ferromagnetic rings

Magnetoresistance and magnetic properties of Fe/Cu/Fe/GaAs(100)
(APS through AIP, 1999-10/01)A procedure for growth of smooth As free Fe surfaces on (46)-GaAs(100) is presented. Ferromagnetic resonance (FMR) revealed that the Fe films have anisotropies equal to bulk Fe, modified only by interface anisotropies. The ...
