Query: Active-Site Motion and Pattern Formation in Self-Organised Interface
  Depinning   We study a dynamically generated pattern in height gradients, centered around
the active growth site, in the steady state of a self-organised interface
depinning model. The pattern has a power-law tail and depends on interface
slope. An approximate integral equation relates the profile to local interface
readjustments and long-ranged jumps of the active site. The pattern results in
a two-point correlation function saturating to a finite value which depends on
system size. Pattern formation is generic to systems in which the dynamics
leads to correlated motion of the active site.
