Networks model of the East Turkistan terrorism
Li, Ben-xian; Zhu, Jun-fang; Wang, Shun-guo - In: Physica A: Statistical Mechanics and its Applications 419 (2015) C, pp. 479-486
The presence of the East Turkistan terrorist network in China can be traced back to the rebellions on the BAREN region … view. The events, terrorists and their relationship are described using matrices. Then social network analysis is adopted … to reveal the network type and the network structure characteristics. We also find the crucial terrorist leader …

A statistical mechanics approach to Granovetter theory
Barra, Adriano; Agliari, Elena - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 10, pp. 3017-3026
In this paper we try to bridge breakthroughs in quantitative sociology/econometrics, pioneered during the last decades by Mac Fadden, Brock–Durlauf, Granovetter and Watts–Strogatz, by introducing a minimal model able to reproduce essentially all the features of social behavior highlighted by...

Extracting deep information from limited observations on an evolved social network
Ormerod, Paul - In: Physica A: Statistical Mechanics and its Applications 378 (2007) 1, pp. 48-52
We provide empirical evidence that in a social network which evolves over time, it is possible to extract deep … their social network. We consider a small amount of straightforward and readily accessible information. We deduce from this …, using an agent-based model, the type of social network across which information and influence on behaviour flows between …

Structured information in sparse-code metric neural networks
Dominguez, David; González, Mario; Rodríguez, Francisco B. - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 3, pp. 799-808
the connections are spatially uniform, the macroscopic properties of the network can be measured by the overlap between … the network. We characterize the structure type of the neural states using a parameter that is related to fluctuations of … between localized (bump), structured (block) and global retrieval. When the network topology randomness increases, the phase …

Ising-based model of opinion formation in a complex network of interpersonal interactions
Grabowski, A.; Kosiński, R.A. - In: Physica A: Statistical Mechanics and its Applications 361 (2006) 2, pp. 651-664
In our work the process of opinion formation in the human population, treated as a scale-free network, is modeled and … investigated numerically. The individuals (nodes of the network) are characterized by their authorities, which influence the … social network, on the process of opinion formation is investigated. It was found that in the time evolution of opinions of …

Efficiency of goal-oriented communicating agents in different graph topologies: A study with Internet crawlers
Lőrincz, András; Lázár, Katalin A.; Palotai, Zsolt - In: Physica A: Statistical Mechanics and its Applications 378 (2007) 1, pp. 127-134
To what extent does the communication make a goal-oriented community efficient in different topologies? In order to gain insight into this problem, we study the influence of learning method as well as that of the topology of the environment on the communication efficiency of crawlers in quest of...

A network of two-Chinese-character compound words in the Japanese language
Yamamoto, Ken; Yamazaki, Yoshihiro - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 12, pp. 2555-2560
Some statistical properties of a network of two-Chinese-character compound words in the Japanese language are reported …. In this network, a node represents a Chinese character and an edge represents a two-Chinese-character compound word. It … is found that this network has properties of being “small-world” and “scale-free”. A network formed by only Chinese …

Epidemics with pathogen mutation on small-world networks
Shao, Zhi-Gang; Tan, Zhi-Jie; Zou, Xian-Wu; Jin, Zhun-Zhi - In: Physica A: Statistical Mechanics and its Applications 363 (2006) 2, pp. 561-566
We study the dynamical behavior of the epidemiological model with pathogen mutation on small-world networks, and discuss the influence of the immunity duration τR, the cross-immunity threshold hthr, and system size N on epidemic dynamics. A decaying oscillation occurs because of the interplay...
