Fig. 1From: Self-organizing scale-free patterns in a phase-modulated periodic connecting systemRank-size relations of number of balls in urns for the case of a total of 3200 balls and 1600 urns (N = 3200, K = 1600) at the 25-millionth iteration of the a, b periodic and c, d phase-modulated periodic connecting systems. In order to comprehend the statistical properties, the rank-ordered frequencies for the systems are plotted in both log-linear coordinates (a, c) and log–log coordinates (b, d)Back to article page
