| 1 | Statistical CSI based design for intelligent reflecting surface assisted MISO systems显示文摘This paper considers an intelligent reflecting surface(IRS)aided multiple-input single-output communication system,where statistical channel state information(CSI)is exploited for transmit beamforming and IRS beamforming.A tight upper bound is derived for the ergodic capacity of the system.Based on which,the joint optimization of transmit beam and IRS beam are studied.Depending on whether a line-of-sight path exists between the access point and user,two different cases,namely,Rician fading and Rayleigh fading,are separately treated.Specifically,for the Rician fading case,an iterative algorithm is proposed,which is guaranteed to converge.For the Rayleigh fading case,closed-form designs are obtained for the transmit beam and IRS beam.Simulation results show the proposed beamforming scheme achieves similar performance as the benchmark algorithm requiring instantaneous CSI. | Xiaoling HU Junwei WANG Caijun ZHONG | 2020 | Science China(Information Sciences)2020，63，12： | 7 |
| 2 | Efficient and stable non-doped deep-blue organic light emitting diode based on an anthracene derivative显示文摘A new anthracene derivative 9,10-bis[3,5-di(4-tert-butylphenyl)phenyl]anthracene (BPPA) was synthesized via Suzuki coupling reaction and characterized by 1H NMR spectrum,mass spectrum,and elemental analysis.BPPA exhibits deep-blue emission both in solution and in solid thin film.This compound has a non-planar structure that results in high thermal stability and the phenomenon of polymorphism.The non-doped device based on this material shows stable deep-blue emission with the 1931 Commission international de I'Eclairage (CIE) coordinate of (0.15,0.05) under different applied voltages.The device exhibits the maximum external quantum efficiency of 2.2% at 14.9 mA/cm2 with luminance of 105 cd/m2. | WANG ZhiQiang ZHENG CaiJun LIU Heng OU XueMei ZHANG XiaoHong | 2011 | Science China Chemistry2011，54，4： | 5 |

| 4 | Adaptive Filter in SAR Interferometry Derived DEM显示文摘In this paper, the performance of median filter, elevation dependent adaptive sigma median filter, and directionally dependent adaptive sigma median filter are tested on both InSAR Tandem DEM and simulated high-level noisy DEM. Through the comparison, the directionally dependent adaptive sigma median filter is proved to be the most effective one not only in the noise removing but also in the boundary preserve. | XU Caijun WANG Hua WANG Jianglin GE Linlin | 2005 | Geo-Spatial Information Science2005，8，3： | 3 |

| 7 | Study on crustal deformation of Wenchuan Ms8.0 earthquake using wide-swath ScanSAR and MODIS显示文摘This paper presents a broad-range study of the co-seismic deformation field of Wenchuan Ms8.0 earthquake by ScanSAR interferometry.The results show co-seismic displacements ranging from-19.8 on the footwall side of the seismogenic fault to 73.6 cm on the hanging-wall side,or from-22.4 to 77.2 cm with atmospheric-delay correction by MODIS.These results differ from the GPS line-of-sight results by 4.58 cm to 2.78 cm,respectively,on the average.We could not obtain the displacements near the earthquake-rupture zone due to incoherence problem. | Xu Caijun Wang Hao Jiang Guoyan | 2011 | Geodesy and Geodynamics2011，2，2： | 1 |

| 14 | Dual threshold search method for asperity boundary determination based on geodetic and seismic catalog data显示文摘As an important model for explaining the seismic rupture mode,the asperity model plays an important role in studying the stress accumulation of faults and the location of earthquake initiation.Taking Qilian-Haiyuan fault as an example,this paper combines geodetic method and b-value method to propose a multi-source observation data fusion detection method that accurately determines the asperity boundary named dual threshold search method.The method is based on the criterion that the b-value asperity boundary should be most consistent with the slip deficit rate asperity boundary.Then the optimal threshold combination of slip deficit rate and b-value is obtained through threshold search,which can be used to determine the boundary of the asperity.Based on this method,the study finds that there are four potential asperities on the Qilian-Haiyuan fault:two asperities(A1 and A2)are on the Tuolaishan segment and the other two asperities(B and C)are on Lenglongling segment and Jinqianghe segment,respectively.Among them,the lengths of asperities A1 and A2 on Tuolaishan segment are 17.0 km and 64.8 km,respectively.And the lower boundaries are 5.5 km and 15.5 km,respectively;The length of asperity B on Lenglongling segment is 70.7 km,and the lower boundary is 10.2 km.The length of asperity C on Jinqianghe segment is 42.3 km,and the lower boundary is 8.3 km. | Xiaohang Wang Zhongzheng Zhou Caijun Xu Yangmao Wen Hu Liu | 2022 | Geodesy and Geodynamics2022，13，4： | 1 |
