A WiMAX-ZigBee energy management system for green education has been developed. The system helps to resolve the disgusting environmental problems. This paper explores the concept of energy management and introduces an Energy Management System located at campus areas. Analysis shows that 30% energy can be saved from the total energy consumption which translates to a saving of 72 thousand million kWh of energy annually. Such saving reduces 48 million tons of CO2 emission for the environment.

The widely adoption of Electric Vehicle (EV) has been identified as a major challenge for future development of smart grids. The ever increasing electric vehicle charging further increases the energy demand. This paper reports the development of an Advanced Metering Infrastructure (AMI) as an effective tool to reshape the load profile of EV charging by adopting appropriate demand side management strategy. This paper presents a total solution for EV charging service platform (EVAMI) based on power line and internet communication. It must be stressed that the development of Third Party Customer Service Platform in this investigation facilitates a single bill to be issued to EV owners. Hence, EV owners understand their energy usage and thus may perform energy saving activity efficiently. Experiment and evaluation of the proposed system show that the throughput achieved is about 5 Mbps at 10 ms end to end delay in Power line Communication. By introducing two dimensional dynamic pricing and charging schedule, the proposed EVAMI successfully reduces 36% peak consumption and increases the “off peak” consumption by 54%. Therefore the EVAMI does not only reduce the peak consumption but also relocates the energy demand effectively.

"朝贡制度"是中国古代史、近代史讨论传统中国对外关系的重要议题,但中外学界一直以来就其定义、范围、作用争论不休。归根究底则由于"朝贡"作为传统经史中对外关系的知识,被近代知识体系碎片化地整合为一"朝贡制度"的"学术概念"。因此,若要解决这些争论则应先从儒家经典释出"朝贡"一词的古义及其在传统经史知识体系的位置,继而分析其在近代知识体系建构与转型的过程中,如何被纳入为中国近代史的命题。最后更要透过剖析费正清"朝贡制度论",指出这一近代转型过程如何造成"朝贡制度"研究视野狭隘、史料单一等问题,从而反思如何突破目前研究困境。

Increasing evidence indicates a role of leptin in immune response, but it remains largely unclear whether leptin signaling is involved in regulating NK cell development in the bone marrow （BM）. In this study, we have characterized NK cell differentiation and maturation in the BM of leptin-receptor deficient db/db mice at a prediabetic stage. Although the BM cellularity was similar to the control value, the total number of NK cells was severely reduced in mutant mice. Flow cytometric analysis of db/db BM cells revealed significantly decreased frequencies of developing NK cells at various stages of differentiation. BM db/db NK cells displayed markedly increased apoptosis but maintained normal cell cycling status and proliferative capacity. Moreover, recombinant leptin could significantly enhance the survival of NK cells from wild-type mice in cultures. Further examination on NK cell functional activity showed that db/db NK cells exhibited normal intrinsic cytotoxicity with significantly increased IL-10 production. Taken together, our findings suggest that leptin signaling regulates NK cell development via enhancing the survival of immature NK cells in mouse BM.
