Identifying node importance in complex networks

Hu, Ping; Fan, Wenli; Mei, Shengwei - In: Physica A: Statistical Mechanics and its Applications 429 (2015) C, pp. 169-176

In this paper, we propose a novel node importance evaluation method from the perspective of the existence of mutual dependence among nodes. The node importance comprises its initial importance and the importance contributions from both the adjacent and non-adjacent nodes according to the...

Information transfer network of global market indices

Kim, Yup; Kim, Jinho; Yook, Soon-Hyung - In: Physica A: Statistical Mechanics and its Applications 430 (2015) C, pp. 39-45

We study the topological properties of the information transfer networks (ITN) of the global financial market indices for six different periods. ITN is a directed weighted network, in which the direction and weight are determined by the transfer entropy between market indices. By applying the...

The independent spreaders involved SIR Rumor model in complex networks

Qian, Zhen; Tang, Shaoting; Zhang, Xiao; Zheng, Zhiming - In: Physica A: Statistical Mechanics and its Applications 429 (2015) C, pp. 95-102

Recent studies of rumor or information diffusion process in complex networks show that in contrast to traditional comprehension, individuals who participate in rumor spreading within one network do not always get the rumor from their neighbors. They can obtain the rumor from different sources...

Weighted k-shell decomposition for complex networks based on potential edge weights

Wei, Bo; Liu, Jie; Wei, Daijun; Gao, Cai; Deng, Yong - In: Physica A: Statistical Mechanics and its Applications 420 (2015) C, pp. 277-283

Identifying influential nodes in complex networks has attracted much attention because of its great theoretical significance and wide application. Existing methods consider the edges equally when designing identifying methods for the unweighted networks. In this paper, we propose an edge...

Epidemic spreading on complex networks with overlapping and non-overlapping community structure

Shang, Jiaxing; Liu, Lianchen; Li, Xin; Xie, Feng; Wu, Cheng - In: Physica A: Statistical Mechanics and its Applications 419 (2015) C, pp. 171-182

Many real-world networks exhibit community structure where vertices belong to one or more communities. Recent studies show that community structure plays an import role in epidemic spreading. In this paper, we investigate how the extent of overlap among communities affects epidemics. In order to...
