Figure 6.

The top panel illustrates the fluctuation $\xi \left(t\right)$ of Equation (56). The bottom illustrates the jumps $z\left(t\right)$ done by the random walker to generate the trajectory $x\left(t\right)$ of Equation (54). The random walker makes a jump ahead of intensity 1 when the fluctuation $\xi \left(t\right)$ of the top panel crosses the border lines between consecutive stripes.
