Figure 4.

Traveling blebs in 2D and 3D. (A) Profile of a traveling bleb in 2D after a perturbation at time $\tau =0$. The membrane height is indicated by the blue line and cortex thickness by the orange line. Parameter values are $\Omega =55$, $ϵ=0.1$, $F_0=1$, $M=0.007$, $P=0.1,$ and $D=0.15$. (B) Profile of a traveling bleb in 3D after a perturbation at time $\tau =0$ in the spatial-heterogeneity hypothesis model, shown at the top (see Results). To see this figure in color, go online.
