Scaling properties of a one-dimensional sandpile model with grain dissipation.
We have studied a stochastic sandpile model with grain dissipation as a generalization of the Oslo sandpile model. During a toppling event, grains are removed from the pile with a probability p. Scaling arguments and simulations suggest that an arbitrarily small dissipation rate p yields a noncritical behavior, in contrast to the robust critical behavior of the Oslo sandpile model.
