| 1 | Energy Efficient Power Allocation for Relay-Aided D2D Communications in 5G Networks显示文摘As one of the key technologies for the fifth generation(5G) wireless networks,device-to-device(D2D) communications allow user equipment(UE) in close proximity to communicate with each other directly.Forwarded by a relay,the relay-aided D2D(RA-D2D) communications can not only be applied to communications in much longer distance but also achieve a high quality of service(Qo S) .In this paper,we first propose a two-layer system model allowing RA-D2 D links to underlay traditional cellular uplinks.Then we maximize the energy efficiency of the RA-D2 D link while satisfying the minimum data-rate of the cellular link.The optimal transmit power at both D2 D transmitter and D2 D relay sides is obtained by transforming the nonlinear fractional programming into a nonlinear parameter programming.Simulation results show that our proposed power allocation method is more energy efficient than the existing works,and the proposed RA-D2 D scheme outperformed direct D2 D scheme when the distance between two D2 D users is longer. | Ru Wang Jia Liu Guopeng Zhang Shuanghong Huang Ming Yuan | 2017 | China Communications2017，14，6： | 13 |
| 2 | Stress Measurement with an Improved Hollow Inclusion Technique In Jinchuan Nickel Mine显示文摘Borehole overcoring stress measurement with an improved hollow inclusion technique was carried out at 10 points on 3 levels in Jinchuan nickel mine which is situated in north-west of China. Through the measurement, 3-D in situ stress state at the measuring points and distribution characteristics of the stress field in the mine were obtained. The stress state in Jinchuan mine is dominated by the horizontal tectonic stress field. The maximum principal stress is horizontal which is about twice the weight of the overburden and its orientation is approximately vertical to the regional tectonic line. The difference between two horizontal principal stresses is quite large which is an important reason to cause failure of underground excavations. | Meifeng Cai, Lan Qiao, Bo Yu, Shuanghong Wang (Resources Engineering School, University of Science and Technology Beijing, Beijing 100083) | 2000 | International Journal of Minerals,Metallurgy and Materials2000，14，3： | 5 |
| 3 | Distribution and characteristics of telocytes as nurse cells in the architectural organization of engineered heart tissues显示文摘Interstitial Cajal-like cells are a distinct type of interstitial cell with a wide distribution in mammalian organs and tissues,and have been given the name'telocytes'.Recent studies have demonstrated the potential roles of telocytes in heart development,renewal,and repair.However,further research on the functions of telocytes is limited by the complicated in vivo environment.This study was designed to construct engineered heart tissue(EHT)as a three-dimensional model in vitro to better understand the role of telocytes in the architectural organization of the myocardium.EHTs were constructed by seeding neonatal cardiomyocytes in collagen/Matrigel scaffolds followed by culture under persistent static stretch.Telocytes in EHTs were identified by histology,toluidine blue staining,immunofluorescence,and transmission electron microscopy.The results from histology and toluidine blue staining demonstrated widespread putative telocytes with compact toluidine blue-stained nuclei,which were located around cardiomyocytes.Prolongations from the cell bodies showed a characteristic dichotomous branching pattern and formed networks in EHTs.Immunofluorescence revealed positive staining of telocytes for CD34 and vimentin with typical moniliform prolongations.A series of electron microscopy images further showed that typical telocytes embraced the cardiomyocytes with their long prolongations and exhibited a marked appearance of nursing cardiomyocytes during the construction of EHTs.This finding highlights the great importance of telocytes in the architectural organization of EHTs.It also suggests that EHT is an appropriate physical and pathological model system in vitro to study the roles of telocytes during heart development and regeneration. | ZHOU Jin WANG Yan ZHU Ping SUN HongYu MOU YongChao DUAN CuiMi YAO AnNing LV ShuangHong WANG ChangYong | 2014 | Science China(Life Sciences)2014，57，2： | 4 |
| 4 | Prediction of Rock Burst with Deep Mining Excavation in Linglong Gold Mine显示文摘To predict rock burst in deep mining excavation in Linglong gold mine, systematical laboratory tests of mechanical properties of rock, in situ stress measurement and 3-D FEM analysis on energy distribution in rock mass surrounding deep mining rooms were carried out. According to various prediction criteria of rock burst, it is concluded that rock burst is liable to occur during deep mining excavation in the mine. | Meifeng Cai, Jinan Wang, Shuanghong Wang Civil and Environmental Engineering School, University of Science and Technology Beijing, Beijing 100083.

| 5 | 北京地区2013–2017年细颗粒物爆发增长事件的演变特征及气象成因分析显示文摘本文详细分析了2013–2017年北京地区细颗粒物爆发增长事件的演变特征,并结合气态前体物和常规气象要素对3种事件类型(3h, 6h和9h事件)的污染来源及其气象成因进行了探讨。北京地区细颗粒物爆发增长事件呈逐年下降趋势,且多发生在秋冬季;事件的生消过程中NO2的增长速率远高于SO2,表明移动源的贡献要高于固定源。风向-风速-PM2.5的polar Plot结果表明,来自北京东南方向气团的污染物输送对于3h事件有较大影响, 9h事件受主要受局地排放及二次转化的影响, 6h事件则源于局地排放和区域传输的共同贡献。 | SHI Shuzhen LIU Zirui XU Zhongjun YANG Shuanghong LIU Jingda WANG Yuesi | 2020 | Atmospheric and Oceanic Science Letters2020，13，1： | 2 |
