Directionality of contact networks suppresses selection pressure in evolutionary dynamics
Naoki Masuda
Individuals of different types, may it be genetic, cultural, or else, with different levels of fitness often compete for reproduction and survival. A fitter type generally has high…
Evolutionary dynamics and fixation probabilities in directed networks
Naoki Masuda, Hisashi Ohtsuki
We investigate the evolutionary dynamics in directed and/or weighted networks. We study the fixation probability of a mutant in finite populations in stochastic voter-type dynamics…
Self-organization of feedforward structure and entrainment in excitatory neural networks with spike-timing-dependent plasticity
Yuko K. Takahashi, Hiroshi Kori, Naoki Masuda
Spike-timing dependent plasticity (STDP) is an organizing principle of biological neural networks. While synchronous firing of neurons is considered to be an important functional b…
Priority queues with bursty arrivals of incoming tasks
N. Masuda, J. S. Kim, B. Kahng
Recently increased accessibility of large-scale digital records enables one to monitor human activities such as the interevent time distributions between two consecutive visits to…
Oscillatory dynamics in evolutionary games are suppressed by heterogeneous adaptation rates of players
Naoki Masuda
Game dynamics in which three or more strategies are cyclically competitive, as represented by the rock-scissors-paper game, have attracted practical and theoretical interests. In e…
Controlling nosocomial infection based on structure of hospital social networks
Taro Ueno, Naoki Masuda
Nosocomial infection raises a serious public health problem, as implied by the existence of pathogens characteristic to healthcare and hospital-mediated outbreaks of influenza and…
