Query: Pattern formation and the mechanics of a motor-driven filamentous system
  confined by cell membranes   Pattern formation and the mechanics of actin filaments and myosin motors that
are confined by a membrane are investigated. By using a coarse-grained
molecular dynamics model, we demonstrate that the competition between depletion
force and motor active force gives rise to actin accumulation in the membrane
vicinity. The actomyosin structure exerts pressure on the membrane, that
converges to a constant for large motor active force due to nematic alignment.
The results are unaltered by filament length and membrane curvature, indicating
the universality of the phenomena. Thus, this study provides a novel mechanism
behind the self-organization of a motor-driven cytoskeletal network into
higher-order structures.
