Spatial prisoner's dilemma optimally played in small-world networks
Naoki Masuda, Kazuyuki Aihara
Cooperation is commonly found in ecological and social systems even when it apparently seems that individuals can benefit from selfish behavior. We investigate how cooperation emer…
Contribution of hidden modes to nonlinear epidemic dynamics in urban human proximity networks
Naoya Fujiwara, Abhijeet R. Sonawane, Koji Iwayama +1
Recently developed techniques to acquire high-quality human mobility data allow large-scale simulations of the spread of infectious diseases with high spatial and temporal resoluti…
Smoothing effect for spatially distributed renewable resources and its impact on power grid robustness
Motoki Nagata, Yoshito Hirata, Naoya Fujiwara +3
In this paper, we show that spatial correlation of renewable energy outputs greatly influences the robustness of power grids. First, we propose a new index for the spatial correlat…
Steady state and mean recurrence time for random walks on stochastic temporal networks
Leo Speidel, Renaud Lambiotte, Kazuyuki Aihara +1
Random walks are basic diffusion processes on networks and have applications in, for example, searching, navigation, ranking, and community detection. Recent recognition of the imp…
A model of competition among more than two languages
Ryo Fujie, Kazuyuki Aihara, Naoki Masuda
We extend the Abrams-Strogatz model for competition between two languages [Nature 424, 900 (2003)] to the case of n(>=2) competing states (i.e., languages). Although the Abrams-Str…
