The acute lung injury (ALI) is a leading cause of morbidity and mortality in critically ill patients. Amygdalin is derived from the bitter apricot kernel, an efficacious Chinese herbal medicine. Although amygdalin is used by many cancer patients as an antitumor agent, there is no report about the effect of amygdalin on acute lung injury. Here we explored the protective effect of amygdalin on ALI using...
In this paper we consider a class of social foraging swarms with nutrient/toxic profiles and general nonlinear attraction and repulsion structure. The emergent behavior of the swarm motion is the result of a balance between inter-individuals interactions and the simultaneous interactions of the swarm with their environment. The interactions among the swarm members considered in the paper is varying...
In this paper we consider stability analysis of a class of of Multi-agent system with leaders and time delays under Gaussian profiles. The leaders and the followers are included in the proposed system, and only the leaders have the knowledge about the environment. The emergent behavior of the system motion is the result of a balance between inter-individuals interactions and the simultaneous interactions...
In this paper we consider a class of social foraging swarms with nutrient/toxic profiles and general nonlinear attraction and repulsion structure, as well as interaction with constant time-delay. The paper considers the condition, which extends some existent results. The emergent behavior of the swarm motion is the result of a balance between inter-individuals interactions and the simultaneous interactions...
In this paper we consider the aggregation stability problem of a multi-agents system with general nonlinear attraction and repulsion forces and interaction constant time delays. The paper considers a general condition which extends the results provided in Shu and Zheng [1]. We show that the agents of multi-agents system with interaction time delays will asymptotically form a cohesive cluster with...

In this paper we consider the aggregation stability problem of a multi-agents system under network, among the agents there are nonlinear attactive/repulsive forces. Our work generalizes the results given by Gazi and Passino [1] and Chu, Wang and Chen [2], [3], [4] into a very general setting. It shows that the agents of multi-agents system in undirect communication network will asymptotically form...
In this paper we study the consensus conditions for multi-agent systems under continuous time-varying network. The dynamics of agents is described by a double-integrator. For such multi-agent systems the connectivity of network is neither sufficient, nor necessary condition. Even if the integral connectivity condition given by [11], [12] is not sufficient condition of its consensus anymore. Under...
This paper investigates the aggregation of dynamical agents in network. The communication topology of network is characterized by a undirect graph and the agents are Lyapunov stable distributed in a plane. We provide with the conditions under which the group of agents will achieves gradually aggregation. Numerical simulations show that our theoretical results are effective. By comparison with the...
