新疆人口地域系统理论与方法体系研究

新疆人口地域系统的理论和方法体系研究是横向和纵向两方面项目资助完成的综合性研究,一方面是和新疆有关厅局委、地州等合作的横向项目,具体包括：受新疆人口和计划生育委员会委托完成的“新疆人口发展战略研究”、“新疆人口发展功能区研究”,自治区建设厅委托的“新疆小城镇发展战略研究”;自治区发改委委托的“小城镇经济发展战略研究”子专题“小城镇人口预测及其承载力研究”以及地州、县级、乡等城镇体系规划、村镇体系规划、新农村建设规划等都涉及到区域人口发展的项目。另一方面是纵向的中国科学院知识创新工程重点项目专题“城市化空间形态的资源环境效应研究”、中国科学院“西部之光”人才培养计划项目“天山北坡绿洲城镇化进程中..

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
