Distributions of the weighted out-degree of node.

(a) Double-logarithmic plot between the weighted out-degree of node and (the whole time series). (b) Cumulative distribution of the weighted out-degree of the node (sorted by the value of the weight out-degree of the nodes in descending order, N = 1,2,…,106). (c) Double-logarithmic plot between the weighted out-degree of node and (the first part of the time series). (d) Double-logarithmic plot between the weighted out-degree of node and (the second part of the time series).
