7. The "cutting" by the particles is not an artifact of the Kawasaki exchange dynamics. Using a model that allows for a "smoother" motion of the particles, we observe the same structure.

11. Note that the mobile particles not only drift in the shear flow but also move randomly in the system. The latter motion "cuts" the long, striped domains that are formed under the imposed advection and, thus, decreases the effect of shear on the domains. Hence, the shear rate is effectively reduced in the presence of the moving particles. We include here a smooth dependence on particle density.
