Joint Routing, MAC, and Link layer Optimization in Sensor Networks with Energy Constraints
Joint Routing MAC Link layer
2015/6/19
We consider sensor networks where energy is a limited resource so that energy consumption must be minimized while satisfying given throughput requirements. Moreover, energy consumption must take into ...
Achievable Secrecy Sum-Rate in a Fading MAC-WT with Power Control and without CSI of Eavesdropper
Channel state information Cooperative jamming Fading Channel Multiple Access Channel Secrecy sumrate
2011/9/21
Abstract: We consider a two user fading Multiple Access Channel with a wire-tapper (MAC-WT) where the transmitter has the channel state information (CSI) to the intended receiver but not to the eavesd...

2009/9/29
采用从头计算方法(HF)对几种膦铑络合物[Rh(R,R)-DIPAMP]+,[Rh(S,S)-CHIRAPH OS]+, [Rh(DIPHOS)]+及它们与乙基-α-乙酰胺基肉桂酸(MAC)结合形成的中间体[Rh(R,R-DIPAMP)(MAC)]+, [Rh(S,S-CHIRAPHOS)(MAC)]+,[Rh(DIPHOS)(MAC)]+的几何结构进行了优化,计算结果显示: (1)采用从头计算方...
Mac-1-FP融合表达载体的构建、Mac-1-FP的表达与活性鉴定
Mac-1 BFP YFP 融合蛋白
2007/12/19
摘要 分别构建表达BFP与CD1 1b的C末端、YFP与CD1 8的N末端相连接的融合蛋白的表达载体 ,并将二者转染至既无内源性Mac 1的表达同时又具有某些炎症反应信号转导系统的CHO细胞株进行表达Mac 1 FP .通过荧光显微镜观察到共转染后的CHO细胞可发出蓝色荧光和黄色荧光 ,应用Western印迹方法确定CD1 1b BFP与YFP CD1 8能够形成二聚体 ,采用流式细胞术检测确定...
Rayleigh-Taylor不稳定性的MAC模拟。
采用相对论赝势abinitio从头算及密度泛函B3LYP方法,对[Rh(DIPHOS)(MAC)]+络合物的结构进行了优化,并将采用不同方法和基组的优化结果与X射线衍射实验数据对照.结果表明用量子化学方法,优化含金属重原子的较大体系中间态的结构是方便可行的.B3LYP方法能改善与Rh有关的结构参数,对P原子加极化d函数还能改善P-Rh键长.
