本文分析了放置于高Q谐振腔中的Josephson结、双结SQUID和单结超导环,当其Joseph-son频率ω=2.V0/h和腔的本征频率相等时,Josephson电流在一个磁通量子内可以产生多次阶梯或振荡的物理本质。指出对于Josephson结或双结SQUID,当ω=ωr时,被激发起的腔的本征振荡将反馈辐照结或SQUID,反馈场的频率作用使Josephson电流产生一般地感应台阶;而反馈场的振幅是受到外磁场调制的,当这种调制作用使反馈场振幅的空间部分与辐射场的空间部分匹配时,则引起电流在一个磁通量子内产生一系列的新的阶跃。对单结超导环,当nω=ωr时,被激发起的腔的振荡反馈辐照作用将迫使其超流电流产生周期小于φ0的振荡。

作者： Xiao Xiao Shuang Xiao Zhenping Hu GuoQin Ning department of Information Jianghan university Wuhan P.R.{2. department of Electronics& Information Engineering Huazhong university of science&technology Wuhan P.R.{2.

＜正＞in this paper, we propose a dynamic subcarrier and power allocation algorithm for MIMO/OFDM multiuser communication systems with beamforming in downlink transmission. The algorithm adaptively controls multiple-access, transmit power and beamforming to exploit the channel variation in space, frequency and user domains. The ultimate objective of the loading algorithm is to optimize the overall power efficiency while ensuring the fulfillment of every user’s QoS requirements. Numerical results show that significant improvement in performance is achievable with reasonable complexity when the above schemes are applied.

＜正＞Objective The phosphatidylinositol-3-kinase-like kinase ATM（Ataxia - telangiectasia mutated） plays a central role in coordinating the DNA damage responses including cell cycle checkpoint control,DNA repair,and apoptosis.
