| 1 | Bank Credit, Firm Entry and Exit, and Economic Fluctuations in China显示文摘这研究探索变得更坏的银行信用质量怎么影响公司入口和出口决定,并且广泛的边缘变化怎么放大金融、工艺的震动的传播到真实经济(即,在广泛的边缘的变化) 。用向量 autoregression (增值商) 当模特儿,我们的实验证据显示那败坏的中国人存条件有的信用对到市场的网公司入口的重要否定影响。在因袭的事实后面探索潜在的机制,我们建立展示固定生产费用,损失相关的银行信用质量震动和由银行网价值的水平限制总数信用供应的内长的资产负债表限制的一个动态随机的一般平衡(DSGE ) 模型。模型模拟显示金融限制和广泛的边缘变化的相互作用在真实经济上放大银行信用震动的影响。当银行经历损失相关的金融震动时,银行信用紧缩外部资助费用,它增加公司。当公司期望收入不是足够的盖住固定生产费用时,一些公司退出从或停止进入市场。作为结果,经济显示严重衰退和慢恢复。 | Ling Feng Yizhong Guan Zhivuan Li | 2014 | Frontiers of Economics in China-Selected Publications from Chinese Universities2014，9，4： | 2 |
| 2 | abrication of CDs hybrid MIL-68(In) derived In2O_(3)eIn_(2)S_(3) hollow tubular heterojunction and their exceptional self-powered PEC aptasensing properties for ampicillin detecting显示文摘A visible-light-driven self-powered photoelectrochemical(PEC)aptasensor was developed for ampicillin(AMP)detecting based on carbon dots(CDs)hybrid MIL-68(In)-derived In2O_(3)eIn_(2)S_(3) hollow tubular heterojunction(CDs/In2O_(3)eIn_(2)S_(3)).In_(2)S_(3) nanosheets uniformly grew in-situ on the surface of In2O_(3) hollow tubes,forming a close contact heterogeneous interface,which significantly promoted the transfer and separation of photo-generated carriers,and provided a large specific surface area and rich active sites for the PEC aptasensing platform.Furthermore,the CDs/In2O_(3)eIn_(2)S_(3)/ITO electrode,which was obtained by dipping assembly,showed remarkable and stable photoelectric signals at zero-bias under visible light irradiation.The amino-functionalized AMP aptamer was fixed on the working electrode as a biological recognition element,and the concentration of AMP was determined by observing the change in photocurrent intensity caused by the specific capture of AMP molecules in solution.Under optimized conditions,the developed PEC aptasensor displayed a relatively wide linear range from 0.001 ng mL^(-1) to 300 ng mL^(-1),as well as a low detection limit(LOD)of 0.06 pg mL^(-1).Besides,the novel self-powered PEC AMP-aptasensor exhibited excellent reproducibility,good stability and selectivity,which open a potential avenue for antibiotic residues detection in environmental media. | Tao Yan Yixuan Feng Xiang Ren Jinkai Li Yizhong Lu Meng Sun Liangguo Yan Qin Wei Huangxian Ju | 2021 | Journal of Materiomics2021，7，4： | 2 |

| 5 | In situ optical spectroscopic understanding of electrochemical passivation mechanism on sol–gel processed WO_(3) photoanodes显示文摘A prevailing understanding on electrochemical activation of photoelectrodes is that electrochemical treatment leads to increased charge carrier densities thereby improved photoelectrode performances.Contrary to this understanding,in this study enhanced photoactivity of WO_(3) photoanode upon electrochemical treatment is ascribed to an extraordinary mechanism of surface trap passivation.The associated mechanism is analyzed by in situ optical spectroscopy,using which the optical property changes of WO_(3) electrode during electrochemical treatment are monitored.The results suggest surface W^(5+)species,the origin of surface traps on WO_(3) photoanodes,are converted to W^(6+) ions by electrochemical treatment.This study demonstrates the particular ability of the electrochemical strategy to passivate surface traps of photoanodes,and also shows the advantages of in situ optical spectroscopy to investigate the real-time electronic structure variations of electrodes during electrochemical treatment. | Jianyong Feng Xin Zhao Bowei Zhang Zhong Chen Zhaosheng Li Yizhong Huang | 2022 | Journal of Energy Chemistry2022，31，8： | 0 |
| 6 | Inhibition of Differentiation by Transforming Growth Factor β1 in Rhabdomyosarcoma Cells显示文摘OBJECTIVE To study the effect of transforming growth factor?1 (TGF-β1)on differentiation of rhabdomyosarcoma(RMS)cells METHODS RD(human embryonal RMS cell line)cells,cultured in differentiation medium containing 9-cis retinoic acid(9CRA),were treated with TGF-β1.Proliferation of the cells was examined by the MTT assay.The differentiation specific proteins(sarcomeric actin and MyHC)and myogenic transcription factors(MyoD1 and myogenin)in the RD cel s were assessed by immunofluorescence staining. RESULTS Compared to control cel s,treatment with lower concentrations of TGF-?1(0.1 and 0.2 ng/ml)induced an increase in OD values after 4 d(P<0.01),whereas higher concentrations of TGF-?1(2 and 5 ng/ml)led to a reduction of cell viability(P<0.01).After exposure to 9CRA,the viability of the cells decreased significantly(P<0.01),while sarcomeric actin,MyHC and myogenin were induced.These changes were antagonized by TGF-β1(0.1 ng/ml).No changes were observed in expression of MyoD1. CONCLUSION The RMS cells,derived from myogenic progenitors are committed to a myogenic fate,but are arrested in the differentiation course by the addition of TGF-?1 which represses some of the myogenic transcription factors. | Shouli Wang Huihua Yao Zhenghong Qin Shigang Li Yizhong Feng Xiuzhen Wang Min Deng Lingling Guo Lifeng Zhang | 2007 | Chinese Journal of Clinical Oncology2007，4，5： | 0 |
