Figure 3. Velocity correlation function.

Figure 3

The normalized velocity correlation function Inline graphic is plotted as a function of dimensionless time Inline graphic. The curves are shown for run-and-tumble of E. coli with persistence parameter Inline graphic (red), run-reverse with Inline graphic (green), and run-reverse-flick with alternating Inline graphic and Inline graphic (blue). The analytical expressions are given in Eqs. (12) and (21), respectively.
