Figure 5.

(A) Rotational pitch and (B) the corresponding rotational frequency for the simulation results (blue circles) and the experimental data from Fig. 1F (red circles). The simulations are obtained for an ensemble of 10³ independent trajectories at zero load using a landscape generated according to Eq. 2, with asymmetry a₁/l₁ = 0.24, a₂/l₂ = 0.47 and varying the force applied in the direction of motion for τ^∗ = 46 ms (see Materials and Methods). The correlation of the pitch and the rotational frequency with the on-axis velocity is provided by the Pearson correlation coefficient ρ. The dashed lines correspond to fitted linear regressions with their corresponding coefficient of determination R². To see this figure in color, go online.
