Aspect ratios and translational or linear rotational speeds of steadily moving cells.

(a) Aspect ratio as a function of viscosity-adhesion length α; the results were obtained with (v₀, μ_tot) = (2.5, 1.5π) for ZS model, and with (v₀, μ_tot) = (5, 1.5π) for ZV model; aspect ratios were computed as ratios of the longest to shortest distances between cell boundary and cell centroid. (b) Dimensionless translational or linear rotational speed of a cell centroid as a function of viscosity-adhesion length α; model parameters are as in panel (a). (c) Aspect ratio as a function of v₀ and μ_tot; the results were obtained with α = 1 for ZV model and with α = 0.5 for ZS model. (d) Radius of rotation of a cell centroid as a function of v₀ and μ_tot, with values of α as in (c). (e) Dimensionless angular velocity of a cell centroid as a function of v₀ and μ_tot, with values of α as in (c).
