一种增强型事件驱动策略的覆盖空洞补偿算法

针对无线传感器网络体系在随机部署过程中出现覆盖空洞的现象,借助于概率模型提出了一种CHCAEDS（基于事件驱动策略的覆盖空洞补偿算法）。该算法首先对随机部署的特性进行验证,给出随机部署表示形式;然后利用概率相关知识对监测区域内覆盖期望和节点数量进行求解,以达到使用最少数量的节点覆盖最大的面积。仿真实验表明,与其他算法相比,CHCAEDS在网络生存周期和算法运行时间上分别提高了12.59%和10.82%

Controlled wrinkle formation via bubble inflation strain engineering

We demonstrate herein a novel strategy that combines both strain engineering and geometrical confinement in one system to realize controlled wrinkling. The location, shape and size of air bubbles entrapped in poly(dimethylsiloxane) (PDMS) devices are precisely controlled via a soft lithography technique. During the Au sputtering process, thin PDMS covers are first stretched due to the bubble inflation under negative pressure. The subsequent Au coating results in Au-PDMS bilayer structure. When returned to atmospheric pressure, wrinkles form on the Au-PDMS bilayer. Furthermore, rational design for more complicated wrinkle patterns is possible with the initial development of strain analysis. We believe this strategy could be applicable to a large range of materials and would find applications in flexible electronics and optics design

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
