TL;DR: In this paper, the percolation transition in growing networks under an Achlioptas process (AP) is studied and the Fisher exponent τ = 2.24(1) for the cluster size distribution is obtained and shown to satisfy the hyperscaling relation.

TL;DR: In this paper, the percolation transition in growing networks under an Achlioptas process (AP) was studied and it was shown that there occurs a percolated transition with varying probability between two nodes chosen by an AP, and the critical point was determined from the power-law behavior of order parameter and the crossing of the fourth-order cumulant at the critical points.

TL;DR: In this paper, a generalized version of the gravity model for population flow was proposed by harnessing the subpopulation properties characterized by both attributes and geography. And the proposed generalized gravity model properly describes the real data, a part of which could not be explained by the conventional gravity model.

TL;DR: The scaling exponents obtained via the finite-size scaling analysis are shown to be consistent with theoretical values of the fractal dimension d(f) and the Fisher exponent τ for the cluster distribution and it is pointed out that strong finite- size effects exist due to the geometric nature of the cluster-size heterogeneity.

Abstract: An individual’s identity in a human society is specified by his or her name. Differently from family names, usually inherited from fathers, a given name for a child is often chosen at the parents’ disposal. However, their decision cannot be made in a vacuum but affected by social conventions and trends. Furthermore, such social pressure changes in time, as new names gain popularity while some other names are gradually forgotten. In this paper, we investigate how popularity of given names has evolved over the last century by using datasets collected in Korea, the province of Quebec in Canada, and the United States. In each of these countries, the average popularity of given names exhibits typical patterns of rise and fall with a time scale of about one generation. We also observe that notable changes of diversity in given names signal major social changes.
