Leaky membrane dynamics.
A concentration difference of particles across a membrane perforated by pores will induce a diffusive flux. If the diffusing objects are of the same length scale as the pores, diffusion may not be simple; objects can move into the pore in a configuration that requires them to back up in order to continue forward. A configuration that blocks flow through the pore may be statistically preferred, ...
متن کاملNonlinear Dynamics of Ion Concentration Polarization in Porous Media: The Leaky Membrane Model
The conductivity of highly charged membranes is nearly constant, due to counter-ions screening pore surfaces. Weakly charged porous media, or “leaky membranes”, also contain a significant concentration of co-ions, whose depletion at high current leads to ion concentration polarization and conductivity shock waves. To describe these nonlinear phenomena the absence of electroosmotic flow, a simpl...
متن کاملSmooth Calibration, Leaky Forecasts, Finite Recall, and Nash Dynamics
We propose to smooth out the calibration score, which measures how good a forecaster is, by combining nearby forecasts. While regular calibration can be guaranteed only by randomized forecasting procedures, we show that smooth calibration can be guaranteed by deterministic procedures. As a consequence, it does not matter if the forecasts are leaked, i.e., made known in advance: smooth calibrati...

متن کاملDynamics of Bilayer Membrane
The theory combines the Rouse model for a single chain with the liquid crystal theory for bilayer membrane developed by Marcelja. Thus the forces acting on a bead within a chain are spring forces, Brownian force and dissipative or viscous force which appear in Rousetheory plus the liquid crystal and lateral pressure forces. The dynamic viscosity of the system is calculated. 1 . Introduction. Ex...
