BACKGROUND INFORMATION Angiotensin-(1-7) [ANG-(1-7)] mediates vasodilation, antiproliferation, anti-apoptosis and antifibrosis, therefore, it opposes the effects of angiotensin II (ANG II). However, the detailed signal transduction mechanism following the Mas receptor activated by ANG-(1-7) is still poorly understood. Src homology2-containing inositol(More)
Keywords: 0-1 Knapsack problem Bio-inspired algorithm Network converting algorithm Optimization Shortest path problem a b s t r a c t The 0-1 knapsack problem is an open issue in discrete optimization problems, which plays an important role in real applications. In this paper, a new bio-inspired model is proposed to solve this problem. The proposed method(More)
How to identify influential nodes is a key issue in complex networks. The degree centrality is simple, but is incapable to reflect the global characteristics of networks. Betweenness centrality and closeness centrality do not consider the location of nodes in the networks, and semi-local centrality, leaderRank and pageRank approaches can be only applied in(More)
This paper presents an adaptive amoeba algorithm to address the shortest path tree (SPT) problem in dynamic graphs. In dynamic graphs, the edge weight updates consists of three categories: edge weight increases, edge weight decreases, the mixture of them. Existing work on this problem solve this issue through analyzing the nodes influenced by the edge(More)
The constrained shortest path (CSP) problem has been widely used in transportation optimization, crew scheduling, network routing and so on. It is an open issue since it is a NP-hard problem. In this paper, we propose an innovative method which is based on the internal mechanism of the adaptive amoeba algorithm. The proposed method is divided into two(More)
Shortest path is among classical problems of computer science. The problems are solved by hundreds of algorithms, silicon computing architectures and novel substrate, unconventional, computing devices. Acellular slime mould P. polycephalum is originally famous as a computing biological substrate due to its alleged ability to approximate shortest path from(More)
