  • Monodisperse domains by proteolytic control of the coarsening instability 

    Derr, Julien, and Andrew D. Rutenberg. 2011. "Monodisperse domains by proteolytic control of the coarsening instability." Physical Review E - Statistical, Nonlinear, and Soft Matter Physics 84(1).
    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. ...
