Comment on Maximal planar networks with large clustering coefficient and power-law degree distribution . Authors' reply
TL;DR: This Comment corrects the error which appeared in the calculation of the degree distribution of random Apollonian networks and the expression of P(k), which gives the probability that a randomly selected node has exactly k edges, has the form P( k) alpha 1/[k(k + 1)(k + 2].

Cooperator-driven and defector-driven punishments: How do they influence cooperation?
TL;DR: A game model is developed where six evolutionary situations with corresponding combinations of strategies are considered, and a semianalytical method is developed to allow for accurate estimations of the boundaries between the phases of full defection and nondefection, which provide valuable insights into how to select and enforce suitable regulation measures to let public cooperation remain prevalent.

Enhancement of cooperation by giving high-degree neighbors more help
Han-Xin Yang,Zhi-Xi Wu +1 more
TL;DR: In this paper, the effect of preferential assistance on cooperation in the donation game was studied and it was shown that there exists an optimal value of α(α) which leads to the highest cooperation level.

Collective firing patterns of neuronal networks with short-term synaptic plasticity.
TL;DR: In this article, the occurrence of synchronous population activities in a neuronal network composed of both excitatory and inhibitory neurons and equipped with short-term synaptic plasticity was investigated, and the collective firing patterns with different macroscopic properties emerged visually with the change of system parameters, and most long-time collective evolution also showed periodic-like characteristics.

Diversity-induced resonance in a globally coupled bistable system with diversely distributed heterogeneity.
TL;DR: In this article , the authors show that a moderate degree of diversity, in form of quenched noise or intrinsic heterogeneity, can significantly strengthen the collective response of coupled extended systems.
