Force balance and membrane shedding at the Red Blood Cell surface [PDF]
, 2006 During the aging of the red-blood cell, or under conditions of extreme echinocytosis, membrane is shed from the cell plasma membrane in the form of nano-vesicles. We propose that this process is the result of the self-adaptation of the membrane surface area to the elastic stress imposed by the spectrin cytoskeleton, via the local buckling of membrane ...

Ignition and Front Propagation in Polymer Electrolyte Membrane Fuel Cells [PDF]
arXiv, 2006 Water produced in a Polymer Electrolyte Membrane (PEM) fuel cell enhances membrane proton conductivity; this positive feedback loop can lead to current ignition. Using a segmented anode fuel cell we study the effect of gas phase convection and membrane diffusion of water on the spatiotemporal nonlinear dynamics - localized ignition and front ...

Creation and Reproduction of Model Cells with Semipermeable Membrane [PDF]
, 2008 A high activity of reactions can be confined in a model cell with a semipermeable membrane in the Schl\"ogl model. It is interpreted as a model of primitive metabolism in a cell. We study two generalized models to understand the creation of primitive cell systems conceptually from the view point of the nonlinear-nonequilibrium physics.

Annexin A4 and A6 induce membrane curvature and constriction during cell membrane repair
Nature Communications, 2017 The role of annexins in cell membrane repair is largely undefined. Here the authors use a model lipid bilayer to show that annexin A4 induces curvature at the membrane free edge and annexin A6 induces constriction force, and find that both annexins are ...
