| 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 |
| 2 | 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 |

| 4 | The Significance of PSA Modified Parameters (F/T)/PSAD for Diagnosing Prostatic Cancer in the Grey Zone of 4~10 ng/ml显示文摘OBJECTIVE To investigate the diagnostic value of modified prostate specific antigen(PSA)parameters in the diagnosis of prostate cancer(PCA) when the serum PSAis in a grey zone of 4~10 ng/ml. METHODS The results of serum PSA determinations of the patients receiving a transrectal ultrasound-guided multiphase prostatic biopsy,were retrospectively analyzed.In the 88 patients with a serum PSA value of 4-10 ng/ml,the final diagnosis of PCA was made in 21,and that of benign prostate hyperplasia(BPH)in 67 patients.The percentage of the free-serum PSA([FPSA]/total-serum PSA[TPSA],F/T),PSA density(PSAD)and the sensitivity and specificity of the new PSA modified parameter(F/T)/PSAD in diagnosing PCA,within a set threshold value,was compared. RESULTS In the 88 patients with serum PSA in the grey zone of 4.0-10.0 ng/ml,there was no significant difference in comparing the TPSA between the 21 PCA patients and 67 BPH patients(P>0.05).However, there was a significant difference in the value of modified PSA parameters, such as F/T,PSAD and(F/T)/PSAD,between the PCA and the BPH groups (P<0.001).As the cut off point-value of the F/T,PSAD and(F/T)/PSAD was set at 0.16,0.15 and 0.8,the diagnostic sensitivity for PCA was 66.7%, 76.2%and 85.7%,and the specificity was 41.8%,43.3%and 68.7%,respectively.There was no significant difference in the sensitivity comparing the modified parameters for diagnosing PCA(P>0.05),whereas an overt predominance was present in the specificity of(F/T)/PSAD for PCAdiagnosis (P<0.05). CONCLUSION In the serum PSA grey zone of 4-10 ng/ml,a modified PSA parameter can improve the PCA diagnostic accuracy rate.With a considerably high sensitivity,application of the(F/T)/PSAD may effectively enhance the diagnostic specificity,which is superior to the F/T and PSAD, and can be expected to be one of the new indices derived from the PSA. | Dongliang Yan Enping Hu Haitao Zhang Sheng Liu Hairong Cai Lei Zhang Yan Zhou | 2007 | Chinese Journal of Clinical Oncology2007，4，5： | 1 |
| 5 | 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 |
| 6 | Development and Economic Effect of Farmers' Specialized Cooperatives显示文摘The paper introduces the present development of farmers' specialized cooperatives in China, points out that although the cooperatives in China develop rapidly, they are generally small and their advantages cannot be given into full play, and then analyzes the development achievements of the cooperatives, for example, they have realized scale benefits, their management system tends to more mature, the economic value of their brands is improved and they have created great economic benefits. The paper also points out the stable development path for the cooperatives, that is, the cooperatives should cooperate with local villages, and take a path of combined village and cooperative development so that the cooperative members can get a stable income; the cooperatives can also cooperate with local leading enterprises, which can help the cooperatives to manage, sell and form their products brands, thus the cooperatives can get loans easily to solve the capital bottleneck of cooperative development and improve the members' incomes. | Huide HUANG Wanzhen ZHANG Enping LIU | 2013 | Asian Agricultural Research2013，5，2： | 0 |
