Long-Term Changes and Trends in the F2 Layer Critical Frequency over Alma-Ata (Kazakhstan) by Galina Gordiyenko, Artur Yakovets, Yurii Litvinov, Murat Zhiganbayev

“…However, the position of the maximum in the time distribution of the difference between the observed foF2 and those calculated in accordance with the regression relationship between foF2 and F10.7 and smoothed with the 11-year window occurred earlier (around 1980) relative to the maximum in the F10.7 distribution (around 1986), which may indicate the influence of an additional (to solar activity) source on the ionosphere, possibly of an anthropogenic nature. …”

Physical layer security of full-duplex relay-assisted D2D networks under outdated CSI by Jingjie SHEN, Guangqiu LI, Yancui LUO, Huizhi LIU

“…The relay aided device to device (D2D) network can improve the spectrum efficiency of D2D users and the physical layer security of cellular user (CU) by sharing spectrum with the cellular network.To further improve their performance, transmit antenna selection can be used at the base station and the relay node of the D2D link, and full duplex technology can be used in the relay node.However, due to the feedback delay and mobility, the channel state information (CSI) used for the antenna selection of cellular link and all D2D links may be outdated.For the physical layer security and reliability in the above scenario, security model of a full duplex relay aided D2D network was proposed in the presence of active eavesdropping and outdated CSI, in which the base station and relay nodes both used transmit antenna selection.The closed-expressions for outage probability, ergodic capacity, probability of non-zero secrecy capacity, secure outage probability, asymptotic secure outage probability of relay aided D2D networks were derived.The numerical calculation and simulation results show that the more the number of base station transmit antennas and relay jamming antennas are, the better the CU security performance is.The outdated CSI will deteriorate the outage and security performance of CU.…”

Spatio-temporal Evolution and Matching Characteristics of Water and Heat Resources in Tibet Plateau in Recent 48 Years by DONG Lingxiao, ZHANG Yanmin, JIANG Peidong, DONG Qianjin

“…Due to the special high altitude,low atmospheric pressure,strong radiation and sufficient sunshine,the water and heat resources in the Tibet Plateau is very rich,and the ecosystem of the Tibet Plateau is very sensitive to climate change and human activities.Therefore,the study on the spatial-temporal evolution and matching characteristics of water and heat resources in Tibet Plateau is of great significance to the development of local agriculture and animal husbandry.This paper calculates the reference crop evapotranspiration from 1970 to 2017 in Tibet Plateau by using Penman-Monteith formula,analyzes the spatial distribution and temporal variation of the reference crop evapotranspiration,and the spatial and temporal patterns of water and heat indictors such as rainfall,temperature,reference crop evapotranspiration and moisture index,establishes the matching model of water and heat resources in Tibet Plateau by considering the factors of rainfall,air temperature and evaporation,and studies the matching characteristics of water and heat resources in Tibet Plateau through the model.The results show that the spatial distribution of water and heat resources in the Tibet plateau basically presents two kinds of characteristics:large in the southeast,small in the northwest,or large in both ends of the southeast and northwest,and small in the central region,and shows a significant upward trend in time.The matching of water and heat resources gradually improves from northwest to southeast,with a significant enhanced trend from 1970 to 2017,which are favorable to the development of local agriculture and animal husbandry.…”
