| 1 | Effect of TMGa flux on GaN films deposited on Ti coated on glass substrates at low temperature显示文摘Highly c-axis-oriented GaN films were deposited on Ti coated glass substrates using low temperature electron cyclotron resonance plasma enhanced metal organic chemical vapor deposition system(ECR-PEMOCVD)with trimethyl gallium(TMGa)as gallium source.The influence of TMGa flux on the properties of GaN films were systematically investigated by reflection high energy electron diffraction(RHEED),X-ray diffraction analysis(XRD),atomic force microscopy(AFM)and Raman scattering.The GaN film with small surface roughness and high c-axis preferred orientation was successfully achieved at the optimized TMGa flux of 1.0 sccm.The ohmic contact characteristic between GaN and Ti layer was clearly demonstrated by the near-linear current-voltage(I-V)curve.The GaN/Ti/glass structure has great potential to dramatically improve the scalability and reduce the cost of solid-state lighting light emitting diodes. | WANG EnPing BIAN JiMing QIN FuWen ZHANG Dong LIU YueMei ZHAO Yue DUAN ZhongWei WANG Shuai | 2013 | Chinese Science Bulletin2013，58，30： | 2 |

| 4 | Scientific objectives of the Hot Universe Baryon Surveyor(HUBS) mission显示文摘The Hot Universe Baryon Surveyor(HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spatially-resolved high-resolution spectroscopy and large field of view,the HUBS mission will be uniquely qualified to measure the physical and chemical properties of the hot gas in the interstellar medium, the circumgalactic medium, the intergalactic medium, and the intracluster medium. These measurements will be valuable for two key scientific goals of HUBS, namely to unravel the AGN and stellar feedback physics that governs the formation and evolution of galaxies, and to probe the baryon budget and multi-phase states from galactic to cosmological scales. In addition to these two goals, the HUBS mission will also help us solve some problems in the fields of galaxy clusters, AGNs, difuse X-ray backgrounds, supernova remnants, and compact objects. This paper discusses the perspective of advancing these fields using the HUBS telescope. | Joel Bregman Renyue Cen Yang Chen Wei Cui Taotao Fang Fulai Guo Edmund Hodges-Kluck Rui Huang Luis C.Ho Li Ji Suoqing Ji Xi Kang Xiaoyu Lai Hui Li Jiangtao Li Miao Li Xiangdong Li Yuan Li Zhaosheng Li Guiyun Liang Helei Liu Wenhao Liu Fangjun Lu Junjie Mao Gabriele Ponti Zhijie Qu Chenxi Shan Lijing Shao Fangzheng Shi Xinwen Shu Lei Sun Mouyuan Sun Hao Tong Junfeng Wang Junxian Wang Q.Daniel Wang Song Wang Tinggui Wang Weiyang Wang Zhongxiang Wang Dandan Xu Haiguang Xu Heng Xu Renxin Xu Xiaojie Xu Yongquan Xue Hang Yang Feng Yuan Shuinai Zhang Yuning Zhang Zhongli Zhang Yuanyuan Zhao Enping Zhou Ping Zhou | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，9： | 1 |

| 7 | The Precursor of GRB211211A:A Tide-induced Giant Quake?显示文摘The equilibrium configuration of a solid strange star in the final inspiral phase with another compact object is generally discussed,and the starquake-related issue is revisited,for a special purpose to understand the precursor emission of binary compact star merger events(e.g.,that of GRB211211A).As the binary system inspirals inward due to gravitational wave radiation,the ellipticity of the solid strangeon star increases due to the growing tidal field of its compact companion.Elastic energy is hence accumulated during the inspiral stage which might trigger a starquake before the merger when the energy exceeds a critical value.The energy released during such starquakes is calculated and compared to the precursor observation of GRB211211 A.The result shows that the energy might be insufficient for binary strangeon-star case unless the entire solid strangeon star shatters,and hence favors a black hole-strangeon star scenario for GRB211211A.The timescale of the precursor as well as the frequency of the observed quasi-periodic-oscillation have also been discussed in the starquake model. | Enping Zhou Yong Gao Yurui Zhou Xiaoyu Lai Lijing Shao Weiyang Wang Shaolin Xiong Renxin Xu Shuxu Yi Garvin Yim Han Yue Zhen Zhang | 2024 | Research in Astronomy and Astrophysics2024，24，2： | 0 |

| 9 | D-SThBILITY TESTING FOR THE INTERVALMATRIX FAMILY显示文摘This paper is concerned with the problem of D-stability testing for the interval matrix family. First, a nonlinearly or affine multilinearly parametrized interval polynomial family is considered. If the mapping from the parameter space to the coefficient space can be expressed as an affine linear mapping of at least two variables, then it is shown that the D-stability of the family is equivalent to that of its low dimensional boundaries. In light of this result, it is proved that to determine the D-stability of an interval matrix family,it suffices to check its n!2n(n-1) n-dimensional exposed faces. Finally the results obtained are extended to the case where the rows or the columns of the matrix family are perturbed independently in different polytopes, and a result analogous to that in the interval case is obtained. | WANG Enping GENG Zhiyong(Institute Of Systems Science, Academia Sinica, Beijing 100080, China) | 1998 | Systems Science and Mathematical Sciences1998，11，3： | 0 |
| 10 | Protective effect of alpha-synuclein knockdown on methamphetamine-induced neurotoxicity in dopaminergic neurons显示文摘The over-expression of α-synuclein is a major factor in the death of dopaminergic neurons in a methamphetamine-induced model of Parkinson's disease. In the present study, α-synuclein knockdown rats were created by injecting α-synuclein-shRNA lentivirus stereotaxically into the right striatum of experimental rats. At 2 weeks post-injection, the rats were injected intraper-itoneally with methamphetamine to establish the model of Parkinson's disease. Expression of α-synuclein mRNA and protein in the right striatum of the injected rats was significantly down-regulated. Food intake and body weight were greater in α-synuclein knockdown rats, and water intake and stereotyped behavior score were lower than in model rats. Striatal dopamine and tyrosine hydroxylase levels were significantly elevated in α-synuclein knockdown rats. Moreover, superoxide dismutase activity was greater in α-synuclein knockdown rat striatum, but the levels of reactive oxygen species, malondialdehyde, nitric oxide synthase and nitrogen monoxide were lower compared with model rats. We also found that α-synuclein knockdown inhibited metham-phetamine-induced neuronal apoptosis. These results suggest that α-synuclein has the capacity to reverse methamphetamine-induced apoptosis of dopaminergic neurons in the rat striatum by inhibiting oxidative stress and improving dopaminergic system function. | Yunchun Tai Ling Chen Enping Huang Chao Liu Xingyi Yang Pingming Qiu Huijun Wang | 2014 | Neural Regeneration Research2014，9，9： | 0 |
| 11 | Robust stabilization of the system family显示文摘The problem of robust stabilization of a system family is studied here. A sufficient condition for the existence of a robust controller is presented under the assumption that there are perturbations both in the numerator and in the denominator of the nominal system. This condition can be given by an inequality that is satisfied by the coefficient vectors of the perturbed polynomials. Based on this, the robust controller family stabilizing the system family can be obtained. Therefore, the condition has the advantages of easy computing and further satisfying other required properties. | WANG Enping HUANG Lin GENG Zhiyong | 2000 | Chinese Science Bulletin2000，45，9： | 0 |
