| 1 | Direct reprogramming of Sertoli cells into multipotent neural stem cells by defined factors显示文摘Multipotent 神经干细胞为房间治疗保持大诺言。到导致的 pluripotent 干细胞以及成熟神经原的成纤维细胞的 reprogramming 建议可能性没有首先建立 pluripotency,把一个严重地区分的体的房间变换成一个 multipotent 状态。这里,我们证明房间从中层导出的那 Sertoli 能直接被变换成拥有神经干细胞性质的一个 multipotent 状态。导致的神经干细胞(iNSCs ) 表示多重 NSC 特定的标记,展出类似于正常 NSC 的全球基因表示侧面,并且能够自强并且区分功能的神经原进神经胶质并且 electrophysiologically。为酷氨酸 hydroxylase (TH ) 积极的导出 iNSC 的神经原污点, γ -aminobutyric 酸,和胆碱 acetyltransferase。另外, iNSCs 能熬过并且产生跟随移植进有牙齿的回转的触处。iNSCs 的产生可以为疾病建模和再生药有重要含意。 | Chao Sheng Qinyuan Zheng Jianyu Wu Zhen Xu Libin Wang Wei Li Haijiang Zhang Xiao-Yang Zhao Lei Liu Ziwei Wang Changlong Guo Hua-Jun Wu Zhonghua Liu Liu Wang Shigang He Xiu-Jie Wang Zhiguo Chen Qi Zhou | 2012 | Cell Research2012，22，1： | 31 |

| 3 | 通过接收函数分析得到的中国大陆莫霍面深度和Vp/Vs比的统一图显示文摘中国大陆由多个地质构造单元复杂拼合而成,自中生代以来经历了强烈而广泛的构造变形。为了更好地理解其地质构造,我们对2009~2010年期间798个宽频带台站记录的共83509个远震波形进行了系统的接收函数分析,其中749个台站是中国地震台网中心数字化固定台站,其他49个台站是在西藏中北部临时部署的台站。每个台站下方的莫霍面深度和Vp/Vs比由标准的远震接收函数H-k叠加方法计算所得。得到的莫霍面深度变化总体上与各种深震探测剖面的结果一致。本文将我们的结果与以往接收函数研究的结果组合起来生成了中国大陆莫霍面深度和Vp/Vs变化的高分辨率图。与以往的研究结果相比,此项新研究涉及更多的台站以及由此生成的莫霍面深度图具有更高的横向分辨率,尤其是在中国东部地区。总的来说,中国大陆莫霍面深度的变化与主要构造单元具有显著的相关性。例如,在中国东部著名的重力梯度线上莫霍面深度有显著的变化。一般来说,Vp/Vs比值图显示出在青藏高原下面、重力梯度带上以及某些火山下面具有相对高的异常。 | Rizheng He Xuefeng Shang Chunquan Yu Haijiang Zhang Robert D.Van der Hilst 李万金 郑雪刚(译) 田宝峰(校) | 2016 | 世界地震译丛2016，47，3： | 0 |
| 4 | Research progress on rare earth up-conversion and near-infrared Ⅱ luminescence in biological applications显示文摘Rare earth luminescence has attracted widespread attention for several decades, among which nearinfrared(NIR) light-related up-conversion luminescence and NIR-Ⅱ luminescence are widely used in the biomedical field. The NIR-related luminescence is widely studied due to the excellent performance, such as good biocompatibility, deep tissue penetration depth, low self-fluorescence and minimal light damage to organisms. In this review, we mainly introduce the mechanism for rare earth up-conversion luminescence, NIR-Ⅱ luminescence and conclude their advantages compared with traditional luminescence.These excellent priorities provide the basis for NIR-related luminescence bioimaging in vivo. Additionally,we hilglight the scheme for the sensitive detection of substances in organisms and various methods for biological therapy. In spite of the existing research, it is outlined that NIR-related luminescence has great potential to be applied in different aspects, expanding perspectives and future challenges of research in related fields. Based on the current scientific achievements, this review can provide reference for research in the areas mentioned above, expand the research direction and arouse a broad interest in different disciplines to pay attention to rare earth luminescence. | Miao Yang Haijiang Gong Dan Yang Lili Feng Shili Gai Fangmei Zhang He Ding Fei He Piaoping Yang | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 5 | An Improved Prediction Model of Vortex Shedding Noise from Blades of Fans显示文摘The main source of the noise of an axial flow fan is the fluctuating pressure field on blade surfaces caused by the shedding of vortices at the trailing edge of blades.An analytical model to predict the vortex shedding noise generated at the trailing edge of blades of axial flow fans was proposed by Lee in 1993.In this model,for mathematical convenience,an idealized vortex street is considered.However,the agreement between the analytical results and the experimental data needs to be improved because of the simplification about the Karman vortex street in the wake of blade.In the present study,a modified model is proposed based on the prediction model by Lee.The boundary layer theory is used to analyze and calculate the boundary layer development on both the pressure and the suction sides of blades.Considering the effect of boundary layer separation on the location of noise source,the predicted overall sound pressure level compares favorably with the experimental data of an axial fan.In the calculation of A-weighted sound pressure level(La),considering the effect of static pressure on radiate energy,the predicted broadband noise with the modified model compares favorably with the experimental data of a multiblade centrifugal fan. | DOU Huashu LI Zhehong LIN Peifeng WEI Yikun CHEN Yongning CAO Wenbin HE Haijiang | 2016 | Journal of Thermal Science2016，25，6： | 0 |
