Wong, Ling Heng; Pattison, Philippa; Robins, Garry - In: Physica A: Statistical Mechanics and its Applications 360 (2006) 1, pp. 99-120

We study spatial embeddings of random graphs in which nodes are randomly distributed in geographical space. We let the edge probability between any two nodes to be dependent on the spatial distance between them and demonstrate that this model captures many generic properties of social networks,...

The spreading of opposite opinions on online social networks with authoritative nodes

Yan, Shu; Tang, Shaoting; Pei, Sen; Jiang, Shijin; … - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 17, pp. 3846-3855

The study of opinion dynamics, such as spreading and controlling of rumors, has become an important issue on social networks. Numerous models have been devised to describe this process, including epidemic models and spin models, which mainly focus on how opinions spread and interact with each...

How community structure influences epidemic spread in social networks

Wu, Xiaoyan; Liu, Zonghua - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 2, pp. 623-630

Two key features of social networks are the community structure and the high clustering coefficient. For understanding their influences on dynamical processes, we present a model with both an adjustable clustering coefficient and an adjustable degree of community. This model has an invariant...

Local model of a scientific collaboration in physics network compared with the global model

Roohi, A.A.; Shirazi, A.H.; Kargaran, A.; Jafari, G.R. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 23, pp. 5530-5537

We have constructed a collaboration network for physicists based in Iran working in different disciplines. By discussing properties like collaborators per author, shortest path, betweenness, and the concept of power in networks for this local model, and comparing with the global model, we...

Empirical analysis of the evolution of a scientific collaboration network

Tomassini, Marco; Luthi, Leslie - In: Physica A: Statistical Mechanics and its Applications 385 (2007) 2, pp. 750-764

We present an analysis of the temporal evolution of a scientific coauthorship network, the genetic programming network. We find evidence that the network grows according to preferential attachment, with a slightly sublinear rate. We empirically find how a giant component forms and develops, and...

Mixed strategy and coevolution dynamics in social networks

Zhong, Weicai; Abbass, Hussein A.; Bender, Axel; Liu, Jing - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 2, pp. 410-417

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...
