简介：在“魔兽争霸”中，精灵族有三个重要人物：恶魔猎手、玛雅和月之女祭师。而他们之间的关系正犹如网络当中的RADIUS、IAS和远程访问服务器。RADIUS是一个让大多数人感到陌生的名字。但是它却被ISP(Internet服务供应商)广泛地应用在网络计费系统当中。而在大中型局域网中PADIUS则被誉为边缘网络的守护者。这篇文章笔者将让大家认识和了解这位“网络边缘的守护者”。

简介：骨头接枝可以被需要用metaphyseal在老病人填满骨头缺点弄碎的远侧的半径骨折。在这回顾，nonrandomized，单个外科医生的学习，我们评估了与使矿物化的骨胶原(MC)使用两块背面的锁住板与或没有扩大的临床、放射线学的结果为老病人与的骨头接枝背面地，metaphyseal弄碎半径破裂。在组1的病人(n=12)在组2用MC骨头接枝申请与背面的锁住的盘子被对待进metaphyseal骨头缺点，和那些(n=12)仅仅与背面的锁住的盘子。临床、放射线学的参数在外科以后在三和12个月被决定。在最后的后续，没有重要差别在2个组之间被注意以手掌倾斜并且光线的倾斜(p=0.80)；然而，尺骨的变化在没有扩大，2与背面的锁住的盘子对待的组显著地增加了(p<0.05)。机能上地，这些组之间没有重要差别。我们的初步的学习建议骨头接枝代用品和背面的锁住盘子可以是的MC的那联合一为有metaphyseal的老病人有用地其他弄碎的远侧的半径骨折。

简介：AbstractPurpose:Comminuted intraarticular distal radial fractures are difficult to treat conservatively and require operative treatment. This study compared the functional outcomes between variable angle volar plating and external fixator with K-wire augmentation in open reduction and internal fixation.Methods:A total of 62 adult patients with comminuted intraarticular distal radius fracture were randomized into 2 groups: volar plate group and external fixator group. These patients aged between 18 and 60 years had unilateral fractures, and agreed to be included in the study. Patients with a history of fracture, bilateral fracture, associated other injuries, delayed injury for more than 2 weeks, open fracture, pre-existing arthrosis or disability, psychiatric illness and pathological fracture were excluded. Patients were followed up at 6 weeks, 3 months, 6 months and 1 year. The assessment of pain, functional activity, range of motion and grip strength was done at each stage of follow-up. The pain and functional activities were assessed by patient rated wrist evaluation (PRWE) score and disabilities of the arm, shoulder and hand (DASH) score.Results:Patients in volar plate group had superior PRWE score and DASH score at each stage of follow-up. At 1 year follow-up, the mean PRWE score were 7.48 for volar plate group and 7.35 for external fixator group; while the mean DASH score was 4.65 for volar plate group and 5.61 for external fixator group. They had better flexion and extension range of movement. They also had better pronation and supination range of motion at initial follow-up, however the difference get attenuated by 1 year. Volar plate group had significantly better grip strength than external fixator group. Complication rates were higher in external fixation group.Conclusion:Fixation with variable angle volar plate results in early wrist mobilization, better range of movement, less pain and disability and early return of function.

简介：我们求婚并且试验性地证明为M照振幅调整(正交调幅)追踪计划的一个通用、盲目的极化状态基于一个没有决定的指导半径的线性Kalman过滤器(RD-LKF)发信号。追踪性能的极化为调音的照阶段移动(QPSK)和16正交调幅信号通过模拟和实验被调查。静态的极化demultiplexing性能和动态追踪能力上的过滤器参数的影响经由模拟被讨论。在modulation-format-independent情形的过滤器参数的优化策略被建议，模拟被执行为QPSK，16QAM，和混合QPSK/16QAM信号评估极化demultiplexing惩罚。最后，建议没有决定的RD-LKF是试验性地，与经常的模量算法的各自的算法和为QPSK和16正交调幅和ultrafast极化追踪的优点的multimodulus算法相比，能力被证实。
