Figure 3: Directionality transition phase diagrams.
From: Embedding dual function into molecular motors through collective motion
The white and shaded regions represent positive and negative 
(i.e., minus- and plus-end-oriented directionality of the motor), respectively. In (a), the dashed line indicates the theoretical estimate of the critical value of Dx, below which directional transition never emerges. The red dot in (b) indicates the theoretically estimated critical point for N = 1. The parameters are the same as those for Fig. 2.
