A free-boundary model of a motile cell explains turning behavior - Fig 1

Asymptotically stable mechanical states (in all cases, α = 0.5): (a) a stationary state of ZS model, (v₀, μ_tot) = (2.5, 0.125π); (b) unidirectional translation in ZV model, (v₀, μ_tot) = (2.5, 2π); (c) rotations in ZS model, (v₀, μ_tot) = (2.5, 0.75π). Pseudo-colors depict distributions of myosin; arrows are actin velocities; a red dashed line/curve shows the trajectory of a centroid.
