Co-occurrence networks of Chinese characters and words, and of English words, are constructed from collections of Chinese and English articles, respectively. Four types of collections are considered, namely, essays, novels, popular science articles, and news reports. Statistical parameters of...

We investigate coevolution dynamics of both individual strategies and social ties as they adapt within the snowdrift game with mixed strategies. We propose a partner selection mechanism based on the concept of trust. Here trust is considered an instrument for an individual both selecting the...

The stochastic resonance (SR) in a second-order linear system driven by a trichotomous noise and an external periodic signal is investigated. By the use of the properties of the trichotomous noise and the Shapiro–Loginov formula, the exact expression for the output spectral amplification (SPA)...

A new conceptual perturbation model for characterizing the temperature fluctuation in living tissues was proposed based on the classical Pennes bioheat transfer equation. Closed-form analytical solutions to the new equation systems were obtained using the Green's function method. The...

In [Y.-B. Xie, T. Zhou, B.-H. Wang, Scale-free networks without growth, Physica A 387 (2008) 1683–1688], a nongrowing scale-free network model has been introduced, which shows that the degree distribution of the model varies from the power-law form to the Poisson form as the free parameter α...

With the help of the characteristic function and the covariance matrix, we study the effect of a dissipative bath on bipartite entanglement in a system of continuous variables with no direct inter-mode coupling. Under the dissipation induced by an Agarwal bath, the time evolution of entanglement...
