Query: Drifting Pattern Domains in a Reaction-Diffusion System with Nonlocal
  Coupling   Drifting pattern domains (DPDs), moving localized patches of traveling waves
embedded in a stationary (Turing) pattern background and vice versa, are
observed in simulations of a reaction-diffusion model with nonlocal coupling.
Within this model, a region of bistability between Turing patterns and
traveling waves arises from a codimension-2 Turing-wave bifurcation (TWB). DPDs
are found within that region in a substantial distance from the TWB. We
investigated the dynamics of single interfaces between Turing and wave
patterns. It is found that DPDs exist due to a locking of the interface
velocities, which is imposed by the absence of space-time defects near these
interfaces.
