Query: Self-organized criticality in an interface-growth model with quenched
  randomness   We study a modified model of the Kardar-Parisi-Zhang equation with quenched
disorder, in which the driving force decreases as the interface rises up. A
critical state is self-organized, and the anomalous scaling law with roughness
exponent alpha=0.63 is numerically obtained.
