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...

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...

Mouse model of type II Bartter's syndrome. II. Altered expression of renal sodium- and water-transporting proteins

Wagner, Carsten A. ; Loffing-Cueni, Dominique ; Yan, Qingshang ; Schulz, Nicole ; Fakitsas, Panagiotis ; Carrel, Monique ; Wang, Tong ; Verrey, François ; Geibel, John P. ; Giebisch, Gerhard ; Hebert, Steven C. ; Loffing, Johannes

ROMK-deficient (Romk–/–) mice exhibit polyuria, natriuresis, and kaliuresis similar to individuals with type II Bartter's form of hyperprostaglandin E syndrome (HPS; antenatal Bartter's syndrome). In the present study, we utilized both metabolic and clearance studies to define the contributions of specific distal nephron segments to the renal salt wasting in these mice. The...
