Time dependencies of max|b_j(t)|t^1/3at different (“small” and “large”) values ofEandCshown in insert. The time dependence ∝t^−1/3is not fulfilled atE= 0,C²= 0.1, andC= 0.5,E= 0 even at timet= 10³, but rather quickly (t≈ 200) this dependence is satisfied at largeEandC. Here, time range 0 ≤t≤ 1000,N= 550.
