(<i>b</i>) Dimensionless translational or linear rotational speed of a cell centroid as a function of viscosity-adhesion length α; model parameters are as in panel (<i>a</i>). (<i>c</i>) Aspect ratio as a function of <i>v</i><sub>0</sub> and μ<sub>tot</sub>; the results were obtained with α = 1 for ZV model and with α = 0.5 for ZS model. (<i>d</i>) Radius of rotation of a cell centroid as a function of <i>v</i><sub>0</sub> and μ<sub>tot</sub>, with values of α as in (c). (<i>e</i>) Dimensionless angular velocity of a cell centroid as a function of <i>v</i><sub>0</sub> and μ<sub>tot</sub>, with values of α as in (c).</p>
