Partial orders for zero-sum arrays with applications to network theory
No full textIn this contribution we study partial orders in the set of zero-sum arrays. Concretely, these partial orders relate to local and global hierarchy and dominance theories. The exact relation between hierarchy and dominance curves is explained. Based on this investigation we design a new approach for measuring dominance or stated otherwise, power structures, in networks. A new type of Lorenz curve to measure dominance or power is proposed, and used to illustrate intrinsic characteristics of networks. The new curves, referred to as D-curves are partly concave and partly convex. As such they do not satisfy Dalton’s transfer principle. Most importantly, this article introduces a framework to compare different power structures as a whole. It is shown that D-curves have several properties making them suitable to measure dominance. If dominance and being a subordinate are reversed, the dominance structure in a network is also reversed.Yuxian Liu's work was supported by NSFC (Grant No.: 71173154), the major project of the National Social Science Fund "Governance of China Network Society" (Grant No. 14ZDA063), and the Fundamental Research Funds for the Central Universities.

Group visible nearest neighbor queries in spatial databases
No full textTraditional nearest neighbor queries and its variants, such as Group Nearest Neighbor Query (GNN), have been widely studied by many researchers. Recently obstacles are involved in spatial queries. The existence of obstacles may affect the query results due to the visibility of query point. In this paper, we propose a new type of query, Group Visible Nearest Neighbor Query (GVNN), which considers both visibility and distance as constraints. Multiple Traversing Obstacles (MTO) Algorithm and Traversing Obstacles Once (TOO) Algorithm are proposed to efficiently solve GVNN problem. TOO resolves GVNN by defining the invisible region of MBR of query set to prune both data set and obstacle set, and traverses obstacle R*-tree only once. The experiments with different settings show that TOO is more efficient and scalable than MTO
Induction and preliminary characterization of a novel halophage SNJ1 from lysogenic Natrinema sp F5
No full textHalophage SNJ1 was induced with mitomycin C from Natrinema sp. strain F5. The phage produces plaques on Natrinema sp. strain J7 only. The phage has a head of about 67 nm in diameter and a tail of 570 nm in length and belongs morphologically to the family Siphoviridae. The phage is strongly salt dependent; NaCl concentration affects the integrity of SNJ1, phage adsorption, and plaque formation. The optimal NaCl concentration for phage adsorption and plaque formation is 30% and 25%, respectively.Halophage SNJ1 was induced with mitomycin C from Natrinema sp. strain F5.
