Central carbon metabolism is the main source of energy required by organisms and it provides precursors for other in vivo metabolic processes. The flux flowing through the pathways involved in central carbon metabolism characterizes its biological function and genetic readout between species or environments. In recent years, using a 13C tracer technique, researchers have measured the flux of central carbon metabolism in Corynebacterium glutamicum under a variety of nutritional and environmental changes or genetic modifications. However, there is no integrated and comparative analysis of these measured flux values. In this study, the flux values of central carbon metabolism in Corynebacterium glutamicum that were obtained in other recent studies were consolidated. A preliminary examination of the distribution characteristics of flux values in each metabolic pathway was conducted and the regression relationship between different fluxes was investigated. The principal components of the flux vector were further extracted and aggregated based on the components, and the general features of flux distribution of central carbon metabolism as well as the influence of environmental and genetic factors on the flux distribution were determined. This study provides a foundation for further investigation into the flux distribution and regulation characteristics of central carbon metabolism.

Group key agreement is the core of secure group communication. In wireless networks, the privacy problem becomes more crucial and urgent for mobile users due to the open nature of radio media. In this paper, we proposed a novel group key agreement protocol based on trusted third Party, applied in collaboration between mobile users for wireless Mesh network. The security verification (PCL logic) and performance analysis show that, our protocol not only provides privacy protection for group members, but also authenticates all participants by adopting certificates. More important, in the proposed protocol, the computation cost and traffics for each group member are largely reduced to improve the implementation efficiency of the protocol. Therefore, our protocol is a novel, reliable group key agreement protocol, and it is well suited for wireless mesh network. © 2011 Published by Elsevier Ltd.

Group key agreement is the core of secure group communication. In wireless networks, the privacy problem becomes more crucial and urgent for mobile users due to the open nature of radio media. In this paper, we proposed a novel group key agreement protocol based on trusted third Party, applied in collaboration between mobile users for IEEE 802.11s wireless Mesh network. The security verification (PCL logic) and performance analysis show that, our protocol not only provides privacy protection for group members, but also authenticates all participants by adopting certificates. More important, in the proposed protocol, the computation cost and traffics for each group member are largely reduced to improve the implementation efficiency of the protocol. Therefore, our protocol is a novel, reliable group key agreement protocol, and it is well suited for IEEE 802.11s wireless mesh network.
