Empirical paths to the spread of information in location-based social networks

Zhou, Ming-Yang ; Xiong, Wen-Man ; Liao, Hao ; Wang, Tong ; Wei, Zong-Wen

In: Journal of Statistical Mechanics: Theory and Experiment, 2018, vol. 2018, no. 12, p. 123404

Spreading phenomena in complex networks have attracted much attention in recent years. However, most of the previous works only concern the critical thresholds and final states of the spread. In this paper, we investigate the empirical spreading paths in real location-based networks and find an abnormal phenomenon that the transferring probability of an epidemic between users varies with...

Pressure-driven insulator-metal transition in cubic phase UO 2

Huang, Li ; Wang, Yilin ; Werner, Philipp

In: EPL (Europhysics Letters), 2017, vol. 119, no. 5, p. 57007

Understanding the electronic properties of actinide oxides under pressure poses a great challenge for experimental and theoretical studies. Here, we investigate the electronic structure of cubic phase uranium dioxide at different volumes using a combination of density functional theory and dynamical mean-field theory. The ab initio calculations predict an orbital-selective insulator-metal...

Link prediction in evolving networks based on popularity of nodes

Wang, Tong ; He, Xing-Sheng ; Zhou, Ming-Yang ; Fu, Zhong-Qian

In: Scientific Reports, 2017, vol. 7, no. 1, p. 7147

Link prediction aims to uncover the underlying relationship behind networks, which could be utilized to predict missing edges or identify the spurious edges. The key issue of link prediction is to estimate the likelihood of potential links in networks. Most classical static-structure based methods ignore the temporal aspects of networks, limited by the time-varying features, such approaches...
