We present our theoretical investigations on the effects of disorder on the electron-phonon interaction in semiconducting GaAs system. Both the temperature (T) and disorder (electron mean free path l) dependences of the electron-phonon scattering rate have been determined. On consideration of the dynamic screening, we find a significant change in the temperature exponent as well as the pre factor from the earlier reported temperature power law dependence result ?T6 obtained under static screening. Also the dynamic screening makes a noticeable change in the character of the dependence of scattering rate on the mean free path from the static screening result.

Nonunion of the humerus in a severely osteoporotic bone is a likely event especially if the fracture is transverse. The management of such a combination is a challenge. Most of the conventional fixation methods are unlikely to succeed as the bone failure precedes implant failure in osteoporosis. The challenge is further compounded in severe osteoporosis when the cortical thickness is affected more severely. We used a coi＇nbination of an intramedullary fibula with a locking plate in 5 cases. The results show that it may be a good combination in such situations as the bone strength is augmented and the plate pullout is less likely.

Unconventional and ＇non-lethal＇ weapons are being used in crowd control regularly nowadays. The use of these arms is not risk-free. The paramilitary forces in 2010 used the old fashioned slingshots for crowd control in Kashmir. A young male suffered from a fracture of the distal humerus due to a marble from a slingshot. He was managed by debridement and plaster splintage. Use of apparently innocuous weapons for crowd control is not without risk, as the projectiles fired from them can achieve high velocities and cause significant damage.

Green tea leaves contain many polyphenolic compounds such as (-)-epicatechin (EC), (-)-epicatechin-3-gallate (ECG), (-)-epigallocatechin (EGC), and (-)epigallocatechin-3-gallate (EGCG). These polyphenol compounds have been implicated to have distinct properties that combat the harmful effects of cell proliferation. They contain certain anti-viral and antibacterial properties that inhibit growth. In this study, 1% green tea and modified lipophilic green tea polyphenols (GTP and LTP) were used in combination with the most commonly prescribed antibiotics to study their effects on gram-positive, gram-negative, and acid-fast bacteria. The results indicated that 1% GTP and 1% LTP provided different synergistic effects on several antibiotics in various bacteria. It was found that 1% GTP works the best synergistically against Enterobacter aerogenes, making the resistant strain susceptible to 8 out of 12 antibiotics used. 1% LTP worked the best on Escherichia coli and was able to convert 7 antibiotic resistant categories to susceptible. In addition, 1% LTP was also able to inhibit the growth of Serratia marcescens synergistically with 3 antibiotics. These results suggest that 1% GTP and 1% LTP provide beneficial effects on selected antibiotics against microbial growth and are able to reverse the antibiotic resistance to susceptible. Green tea polyphenols could serve as natural alternatives to combat against antibiotic resistance pathogens.

“物联网”(IOT)包含一个概念,即物体最终成为互联网的一部分:每个物体都有其唯一的标识,可以从网络上访问,从而提供一个扩展的未来互联网。射频识别(RFID)是一种交换条形码的无线技术。这种技术在当今世界被用来跟踪物品和人员。它由三个组件组成:标签、阅读器和中间件。RFID标签存储数据,读卡器用于识别标签中存储的数据或将数据写入标签,而RFID中间件是将读卡器从标签获取的数据与公司库存或数据库连接起来的应用程序。射频识别技术是一种智能识别技术。与传统的自动识别技术相比,具有体积小、成本低、存储量大、可重用、安全性高等优点。RFID阅读器具有读取位于其范围内的多个标签的能力。当发生这种情况时,在读卡器端发生标签冲突的概率很高。为了避免标签冲突,实现了防冲突协议。时隙ALOHA是用于RFID的主要防碰撞协议之一。论文的前半部分重点介绍了基于纯ALOHA和时隙ALOHA的基本防碰撞协议及其数学推导。我们已经解释了纯ALOHA算法不包含恢复和检测机制。它只能使读卡器以一定的角度正确地识别和接收标签发送的数据信号,并在一定的时间点发送。读卡器感知接收到的信息,并决定它是正确接收还是发生冲突。如果发生冲突,标签将保持很长时间并重新发送信息。等待方式的读卡器发送请求信号,读卡器范围内的标签通过随机选择一个槽来识别命令并回复读卡器,以便将标签识别号发送给读卡器。当多个标签响应同一插槽时,会发生冲突。碰撞的标签需要再次读取。如果没有任何标记响应请求命令,那么请求命令将以循环间隔重复。如果读卡器识别标签标识号时没有错误(冲突),则可以使用选择信号选择检测到的标签,以执行读/写操作,而不会与其他标签发生冲突。当发送大量标签时,在某个时间点,在读卡器区域内有多个标签的可能性非常高。当标签同时向读卡器发送响应时,会发生冲突,因为通信是通过共享无线通道进行的。因此,由于可用的射频识别装置数量多,因此,这种高概率的碰撞是一个需要解决的重要问题。本文提出了一个无干扰时隙ALOHA协议行为的数学模型和模拟器。标签检测与读卡器检测到的标签强度直接相关。当环境中存在物体时,射频信号的作用不同。例如,水吸收无线电信号。当环境中存在水颗粒时,标签检测将无效,因为无线电信号将被水吸收。因此,水被认为是标签检测中的干扰约束。本文还提出了一个分析时隙ALOHA协议抗干扰性能的数学模型和模拟器。两组结果的比较表明,所提出的数学模型和模拟器是准确的。分析结果表明,识别有干扰的标签所需的时间比识别无干扰的标签所需的时间长。
