| 1 | Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF. | Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun | 2018 | Science China(Life Sciences)2018，61，12： | 43 |
| 2 | Geometric Mean Decomposition Based Hybrid Precoding for Millimeter-Wave Massive MIMO显示文摘Hybrid precoding can reduce the number of required radio frequency(RF)chains in millimeter-Wave(mmWave) massive MIMO systems. However, existing hybrid precoding based on singular value decomposition(SVD) requires the complicated bit allocation to match the different signal-to-noise-ratios(SNRs) of different sub-channels. In this paper,we propose a geometric mean decomposition(GMD)-based hybrid precoding to avoid the complicated bit allocation. Specifically,we seek a pair of analog and digital precoders sufficiently close to the unconstrained fully digital GMD precoder. To achieve this, we fix the analog precoder to design the digital precoder, and vice versa. The analog precoder is designed based on the orthogonal matching pursuit(OMP) algorithm, while GMD is used to obtain the digital precoder. Simulations show that the proposed GMD-based hybrid precoding achieves better performance than the conventional SVD-based hybrid precoding with only a slight increase in complexity. | Tian Xie Linglong Dai Xinyu Gao Muhammad Zeeshan Shakir Jianjun Li | 2018 | China Communications2018，15，5： | 17 |

| 4 | Valence band structure of strained Si/(111)Si_(1-x)Ge_x显示文摘The strained Si techique has been widely adopted in the high-speed and high-performance devices and circuits. Based on the valence band E-k relations of strained Si/(111)Si1-xGex, the valence band and hole effective mass along the [111] and [-110] directions were obtained in this work. In comparison with the relaxed Si, the valence band edge degeneracy was partially lifted, and the significant change was observed band structures along the [111] and [-110] directions, as well as in its corresponding hole effective masses with the increasing Ge fraction. The results obtained can provide valuable references to the investigation concerning the Si-based strained devices enhancement and the conduction channel design related to stress and orientation. | SONG JianJun, ZHANG HeMing, HU HuiYong, DAI XianYing & XUAN RongXi Key Laboratory of Wide Band-Gap Semiconductor Materials and Devices, School of Microelectronics, Xidian University, Xi’an 710071, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，3： | 9 |
| 5 | Avian influenza A(H7N9)virus:from low pathogenic to highly pathogenic显示文摘OriginalTranslation The avian influenza A(H7N9)virus is a zoonotic virus that is closely associated with live poultry markets.It has caused infections in humans in China since 2013.Five waves of the H7N9 influenza epidemic occurred in China between March 2013 and September 2017.H7N9 with low-pathogenicity dominated in the first four waves,whereas highly pathogenic H7N9 influenza emerged in poultry and spread to humans during the fifth wave,causing wide concern.Specialists and officials from China and other countries responded quickly,controlled the epidemic well thus far,and characterized the virus by using new technologies and surveillance tools that were made possible by their preparedness efforts.Here,we review the characteristics of the H7N9 viruses that were identified while controlling the spread of the disease.It was summarized and discussed from the perspectives of molecular epidemiology,clinical features,virulence and pathogenesis,receptor binding,T-cell responses,monoclonal antibody development,vaccine development,and disease burden.These data provide tools for minimizing the future threat of H7N9 and other emerging and re-emerging viruses,such as SARS-CoV-2. | William J.Liu Haixia Xiao Lianpan Dai Di Liu Jianjun Chen Xiaopeng Qi Yuhai Bi Yi Shi George F.Gao Yingxia Liu | 2021 | Frontiers of Medicine2021，15，4： | 4 |
| 6 | Penetration depth at various Raman excitation wavelengths and stress model for Raman spectrum in biaxially-strained Si显示文摘The carrier mobility of Si material can be enhanced under strain,and the stress magnitude can be measured by the Raman spectrum.In this paper,we aim to study the penetration depths into biaxially-strained Si materials at various Raman excitation wavelengths and the stress model corresponding to Raman spectrum in biaxially-strained Si.The experimental results show that it is best to use 325 nm excitation to measure the material stress in the top strained Si layer,and that one must pay attention to the distortion of the buffer layers on measuring results while 514 nm excitation is also measurable.Moreover,we established the stress model for Raman spectrum of biaxially-strained Si based on the Secular equation.One can obtain the stress magnitude in biaxially-strained Si by the model,as long as the results of the Raman spectrum are given.Our quantitative results can provide valuable references for stress analysis on strained materials. | SONG JianJun YANG Chao HU HuiYong DAI XianYing WANG Cheng ZHANG HeMing | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，11： | 3 |

| 8 | Timing,Displacement and Growth Pattern of the Altyn Tagh Fault:A Review显示文摘The Altyn Tagh Fault(ATF) is the longest, lithospheric scale and strike-slip fault in East Asia. In the last three decades, multidisciplinary studies focusing on the timing, displacement of strikeslip and growth mechanics of the ATF have made great progresses. Most studies revealed that the ATF is a sinistral strike-slip and thrust fault, which underwent multiple episodes of activation. The fault is oriented NEE with a length of 1600 km, but the direction, timing of activity and magnitude of its extension eastward are still unclear. The AFT was predominately active during the Mesozoic and Cenozoic, in relation to the Mesozoic collision of the Cimmerian continent(Qiangtang and Lhasa block) and Cenozoic collision of India with Asia. The AFT strike-slipped with a left-lateral displacement of ca. 400 km during the Cenozoic and the displacement were bigger in the western segment and stronger in the early stage of fault activation. The slip-rates in the Quaternary were bigger in the middle segment than in the western and eastern segment. We roughly estimated the Mesozoic displacement as ca. 150-300 km. The latest paleomagnetic data showed that the clockwise vertical-axis rotation did not take place in the huge basins(the Tarim and Qaidam) at both side of ATF during the Cenozoic, but the rotation happened in the small basins along the ATF. This rotation may play an important role on accommodating the tectonic deformation and displacement of the ATF. Even if we have achieved consensus for many issues related to the ATF, some issues still need to be study deeply; such as:(a) the temporal and spatial coupling relationship between the collision of Cimmerian continent with Asia and the history of AFT in the Mesozoic and(b) the tectonic deformation history which records by the sediments of the basins within and at both side of AFT and was constrained by a high-resolution and accurate chronology such as magnetostratigraphy and paleomagnetic data. | DAI Shuang DAI Wei ZHAO Zhenbin LUO Junhua QIANG Lei MA Xin ZHANG Xianwen XU Jianjun | 2017 | Acta Geologica Sinica(English Edition)2017，91，2： | 3 |
| 9 | Preventing crash in stock market:The role of economic policy uncertainty during COVID‑19显示文摘This paper investigates the impact of economic policy uncertainty(EPU)on the crash risk of US stock market during the COVID-19 pandemic.To this end,we use the GARCHS(GARCH with skewness)model to estimate daily skewness as a proxy for the stock market crash risk.The empirical results show the significantly negative correlation between EPU and stock market crash risk,indicating the aggravation of EPU increase the crash risk.Moreover,the negative correlation gets stronger after the global COVID-19 outbreak,which shows the crash risk of the US stock market will be more affected by EPU during the epidemic. | Peng‑Fei Dai Xiong Xiong Zhifeng Liu Toan Luu Duc Huynh Jianjun Sun | 2021 | Financial Innovation2021，7，1： | 2 |
