  • Pulling helices inside bacteria: imperfect helices and rings 

    Allard, J. F., and A. D. Rutenberg. 2009. "Pulling helices inside bacteria: imperfect helices and rings." Physical Review Letters 102(15): 158105.
    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 ...

  • Steady-state helices of the actin homolog MreB inside bacteria: dynamics without motors 

    Allard, J. F., and A. D. Rutenberg. 2007. "Steady-state helices of the actin homolog MreB inside bacteria: dynamics without motors." Physical review.E, Statistical, nonlinear, and soft matter physics 76(3 Pt 1): 031916.
    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 ...
