Relation between the quiet time Δti and the size si+1 of the following avalanche.
The quantity δP(si+1 < s0, Δti < t0) as a function of s0 for different t0 values and different conditions, non-driven, driven and disinhibited (PTX). Each curve represents an average over all experimental samples in a given condition. The bar on each point is 2σ(si+1 < s0, Δti < t0). (a) Non-driven; (b) Driven; (c) Disinhibited (PTX). Insets: The ratio δP(si+1 < s0, Δti < t0)/σ as a function of s0 for different values of t0; dashed lines delimit the interval (−2, 2). In most cases δP(si+1 < s0, Δti < t0)/σ is much larger than 2. Therefore these results are significant at a level generally lower than 0.05 and give solid evidences of correlations between avalanches and preceding quiet times.
