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

<p>Asymptotically stable mechanical states (in all cases, <i>α</i> = 0.5): (<i>a</i>) a stationary state of ZS model, (<i>v</i><sub>0</sub>, μ<sub>tot</sub>) = (2.5, 0.125<i>π</i>); (<i>b</i>) unidirectional translation in ZV model, (<i>v</i><sub>0</sub>, μ<sub>tot</sub>) = (2.5, 2<i>π</i>); (<i>c</i>) rotations in ZS model, (<i>v</i><sub>0</sub>, μ<sub>tot</sub>) = (2.5, 0.75<i>π</i>). Pseudo-colors depict distributions of myosin; arrows are actin velocities; a red dashed line/curve shows the trajectory of a centroid.</p>
