Figure 4.

(a) The histogram of exponent α in the scaling region of large timescales in DFA. The solid bars represent numbers of cells exhibiting pattern A, and the open bars represent numbers of cells exhibiting pattern B, possessing the specified value of α. (b) The relation between the number of coupled cells and the exponent, α. The horizontal axis represents the number of cells in a single cluster. The vertical axis represents the average of the exponent, α, in the scaling region of large timescales in DFA. The number of samples is indicated on the top of each bar. Note that there is no significant difference in the value of α over different sizes of clusters.
