Membrane dynamics in the regime that cross-linking and retrogarde flow are balanced.

(a) Initial (b) early and (c) late steady configuration of the membrane for na = 0.1 nm−1, Fe = 12 pN, . The insets in panels (a)-(c) shows the filaments status under the membrane. The light-blue lines represent the free fluctuating filaments while the black line shows the filaments in their attached state. The red line shows the non-progressive gel front located at y = 0. (d) Time evolution of the middle point of the membrane and the little arrows show the points where the data for the (a)-(c) plots are collected.
