Regulatory T (Treg) cells respond to immune and inflammatory signals to mediate immunosuppression, but how the functional integrity of Treg cells is maintained under activating environments is unclear. Here we show that autophagy is active in Treg cells and supports their lineage stability and survival fitness. Treg cell-specific deletion of Atg7 or Atg5,(More)
Distributed real-time embedded (DRE) systems are becoming increasingly common and important as the underlying technology for distributed computing and networking systems continues to develop. Efficient task scheduling is essential for achieving high performance in the application of embedded systems. However, because of its NP-hard nature, there are mainly(More)
This paper focuses on the problem of Guaranteed cost control of uncertain T-S fuzzy systems. Based on observer design, the guaranteed cost output feedback control law which guarantees that the closed-loop uncertain T-S fuzzy system is robustly asymptotically stable is proposed. By utilizing the Lyapunov function together with the linear matrix inequality(More)
In order to solve the limitation of existed routing protocol in balancing the tolerance to failures and attacks towards wireless sensor network, we design a robust routing protocol based on complex networks theory, which can adjust the self organization clustering evolution in terms of a threshold function with three coefficient alpha, beta and lambda,(More)
Several wireless sensor network applications ought to decide the intrinsic variance between energy efficient communication and the requirement to attain preferred quality of service (QoS) such as packet delivery ratio, delay and to reduce the power consumption of wireless sensor nodes. Also the intended protocols that are developed aims in providing better(More)
Sensor networks have recently gained a lot of attention from the research community. To ensure scalability sensor networks are often partitioned into clusters, each managed by a cluster head. Since sensors self organize in the form of clusters within a hierarchal wireless sensor network, it is necessary for a sensor node to perform target tracking(More)
Multi-agent coordinate mechanism research has attracted increasing attention in recent years. Researches on the problem mainly focus on how to organize and coordinate relations between agents. The composition of different agents is an issue that must be faced by developers. This paper introduces an automatic agent combination method oriented to workflow(More)
It is a critical consideration to collect and fuse sensed information in an energy efficient manner for obtaining a long lifetime of the sensor network. Based on our findings that the conventional methods of direct transmission, shortest path routing, and Dempster-Shafer tool may not be optimal for data fusion of sensor networks, we propose LEECF(More)
