Characteristics of microRNA co-target networks

Lee, Chang-Yong - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 14, pp. 2728-2737

analyzed by the nearest-neighbor average connectivity, and it was shown that the more assortative a microRNA network is, the … wider the range of increasing average connectivity. In particular, an assortative network has a power-law relationship of … the average connectivity with a positive exponent. A percolation analysis of the network showed that, although the network …

A deterministic small-world network created by edge iterations

Zhang, Zhongzhi; Rong, Lili; Guo, Chonghui - In: Physica A: Statistical Mechanics and its Applications 363 (2006) 2, pp. 567-572

Small-world networks are ubiquitous in real-life systems. Most previous models of small-world networks are stochastic. The randomness makes it more difficult to gain a visual understanding on how do different nodes of networks interact with each other and is not appropriate for communication...

Epidemics and immunization on Euclidean distance preferred small-world networks

Guo, Wei-Ping; Li, Xiang; Wang, Xiao-Fan - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 684-690

In this paper, we propose a novel Euclidean distance preferred model yielding small-world networks in the Euclidean space, on which the epidemics dynamics is investigated. A novel local region immunization strategy is proposed to suppress the epidemic prevalence on the Euclidean small-world...

Global synchronization in general complex delayed dynamical networks and its applications

Zhou, Jin; Xiang, Lan; Liu, Zengrong - In: Physica A: Statistical Mechanics and its Applications 385 (2007) 2, pp. 729-742

The main objective of the present paper is further to investigate global synchronization of a general model of complex delayed dynamical networks. Based on stability theory on delayed dynamical systems, some simple yet less conservative criteria for both delay-independent and delay-dependent...

Nonextensive aspects of small-world networks

Hasegawa, Hideo - In: Physica A: Statistical Mechanics and its Applications 365 (2006) 2, pp. 383-401

Nonextensive aspects of the degree distribution in Watts–Strogatz (WS) small-world networks, PSW(k), have been discussed in terms of a generalized Gaussian (referred to as Q-Gaussian) which is derived by the three approaches: the maximum-entropy method (MEM), stochastic differential equation...

Sandpile on directed small-world networks

Pan, Gui-Jun; Zhang, Duan-Ming; Yin, Yan-Ping; He, Min-Hua - In: Physica A: Statistical Mechanics and its Applications 383 (2007) 2, pp. 435-442

We numerically investigate the avalanche dynamics of the Bak–Tang–Wiesenfeld sandpile model on directed small-world networks. We find that the avalanche size and duration distribution follow a power law for all rewiring probabilities p. Specially, we find that, approaching the thermodynamic...

Geometric phase-transition on systems with sparse long-range connections

Argollo de Menezes, M; Moukarzel, C.F; Penna, T.J.P - In: Physica A: Statistical Mechanics and its Applications 295 (2001) 1, pp. 132-139

Small-world networks are regular structures with a fraction p of regular connections per site replaced by totally random ones (“shortcuts”). This kind of structure seems to be present on networks arising in nature and technology. In this work we show that the small-world transition is a...
