Query: Self-Organized Critical Directed Percolation   We introduce and study a dynamic transport model exhibiting Self-Organized
Criticality. The novel concepts of our model are the probabilistic propagation
of activity and unbiased random repartition of energy among the active site and
its nearest neighbors. For space dimensionality $d\geq 2$ we argue that the
model is related to $d+1$ dimensional directed percolation, with time
interpreted as the preferred direction.
