| 1 | IPO initial returns in China: Underpricing or overvaluation?显示文摘This paper separates the amount of IPO underpricing(primary market underpricing) and overvaluation(secondary market overvaluation) from the value of an IPO's initial return to evaluate the relative importance of these two factors and their main determinants. Using data on the IPOs of 948 Chinese firms, we find that average initial returns are 66% and that underpricing and overvaluation are between 14–22% and 44–53%, respectively, depending on the method used to assess firms' intrinsic values. In addition, while both the value of the initial return and the extent of overvaluation are significantly negatively related to post-IPO long-run stock performance, overvaluation can predict post-IPO performance better than the value of the initial return. Value uncertainty in IPOs is positively related to both underpricing and overvaluation, and both the underwriter's reputation and the existence of pricing regulation are positively related to underpricing. Investor sentiment has a positive effect on overvaluation but has no effect or a negative effect on underpricing. Overall, our results suggest that in China overvaluation accounts for a larger proportion of the initial return than underpricing,and that underpricing and overvaluation have different determinants. | Shunlin Song JinSong Tan Yang Yi | 2014 | China Journal of Accounting Research2014，，1： | 19 |
| 2 | Application of autocorrelation method on ionospheric short--term forecasting in China显示文摘Adopting the autocorrelation method in the ionospheric short-term forecasting, we put for- ward a simple and practical forecasting method― the sectional autocorrelation method, that is, for pre- dictions of one hour to four hours ahead the auto- correlation coefficient of RDF with the “iteration” method is selected, for prediction of more than four hours ahead, the autocorrelation coefficient of f0F2 with the “at once” method is used. The prediction precisions have been quantitatively estimated based on the data from Chongqing and Guangzhou Ionos- onde Stations. It is shown that the method is much improved for the predictions of one hour to four hours ahead. For the predictions of more than four hours ahead the prediction error reaches a saturation value, which is still lower than that of the “median” method. This new method could also be applied to the short-term forecasting of other ionospheric parame- ters. | LIU Ruiyuan LIU Shunlin XU Zhonghua WU Jian WANG Xianyi ZHANG Beichen HU Hongqiao | 2006 | Chinese Science Bulletin2006，51，3： | 17 |
| 3 | A long-term Global LAnd Surface Satellite(GLASS)data-set for environmental studies显示文摘Recently,five Global LAnd Surface Satellite(GLASS)products have been released:leaf area index(LAI),shortwave broadband albedo,longwave broadband emissivity,incident short radiation,and photosynthetically active radiation(PAR).The first three products cover the years 19822012(LAI)and 19812010(albedo and emissivity)at 15 km and 8-day resolutions,and the last two radiation products span the period 20082010 at 5 km and 3-h resolutions.These products have been evaluated and validated,and the preliminary results indicate that they are of higher quality and accuracy than the existing products.In particular,the first three products have much longer time series,and are therefore highly suitable for various environmental studies.This paper outlines the algorithms,product characteristics,preliminary validation results,potential applications and some examples of initial analysis of these products. | Shunlin Liang Xiang Zhao Suhong Liu Wenping Yuan Xiao Cheng Zhiqiang Xiao Xiaotong Zhang Qiang Liu Jie Cheng Hairong Tang Yonghua Qu Yancheng Bo Ying Qu Huazhong Ren Kai Yu John Townshend | 2013 | International Journal of Digital Earth2013，6，S01： | 16 |
| 4 | A dual-pass data assimilation scheme for estimating surface fluxes with FY3A-VIRR land surface temperature显示文摘In this work, a dual-pass data assimilation scheme is developed to improve predictions of surface flux. Pass 1 of the dual-pass data assimilation scheme optimizes the model vegetation parameters at the weekly temporal scale, and Pass 2 optimizes the soil moisture at the daily temporal scale. Based on ensemble Kalman filter(EnKF), the land surface temperature(LST) data derived from the new generation of Chinese meteorology satellite(FY3A-VIRR) are assimilated into common land model(CoLM) for the first time. Six sites, Daman, Guantao, Arou, BJ, Miyun and Jiyuan, are selected for the data assimilation experiments and include different climatological conditions. The results are compared with those from a dataset generated by a multi-scale surface flux observation system that includes an automatic weather station(AWS), eddy covariance(EC) and large aperture scintillometer(LAS). The results indicate that the dual-pass data assimilation scheme is able to reduce model uncertainties and improve predictions of surface flux with the assimilation of FY3A-VIRR LST data. | XU TongRen LIU ShaoMin XU ZiWei LIANG ShunLin XU Lu | 2015 | Science China Earth Sciences2015，58，2： | 9 |
| 5 | Improvement of Dark Object Method in Atmospheric Correction of hyperspectral remotely sensed data显示文摘The existing methods in atmospheric correction of hyperspectral data usually focus on removing the effects of water vapor and other absorptive gases, while this paper mainly studies the method of re- moving the influence of the aerosol and the water vapor simultaneously. Because the hyperspectral data has a larger number of bands, the conventional dark object method cannot be applied to the at- mospheric correction of the hyperspectral data which can be improved, as described in this paper, by adequately making use of spectral characteristics of the hyperspectral data with an iterative correction during the whole process. The effects of the aerosol and water vapor are eliminated at the same time finally. The improved dark object method is used to do the atomospheric correction of the Hyperion data in Yanzhou, Shandong Province as an example. And the result indicates that it can correct the atmospheric influence of the hyperspectral data quickly and remarkably. | ZHAO Xiang LIANG ShunLin LIU SuHong WANG JinDi QIN Jun LI Qing LI XiaoWen | 2008 | Science China Earth Sciences2008，51，3： | 8 |
| 6 | Preliminary evaluation of the long-term GLASS albedo product显示文摘Land surface albedo is an important parameter to describe the radiant forcing in the climate system.A long-time series of global albedo products is needed to understand the mechanism of climate change.Aiming to support global change and Earth system studies,GLASS(Global LAnd Surface Satellites)provides long-term global land surface albedo product from 1981 to 2010,which are generated from multisource remote sensing data and newly developed algorithms.It is critical to assess the quality of the GLASS product when it is released to the public.This paper first introduced the algorithms and then analyzed the integrity,accuracy,and robustness of the GLASS albedo product.The results show that the GLASS albedo product is a gapless,long-term continuous,and self-consistent data-set with an accuracy similar to that of the widely acknowledged MODIS MCD43 product.The quality flag,which is provided along with the black-sky and white-sky albedo,gives a pertinent indication of the expected uncertainty in the product. | Qiang Liua Lizhao Wang Ying Qu Nanfeng Liu Suhong Liu Hairong Tang Shunlin Liang | 2013 | International Journal of Digital Earth2013，6，S01： | 7 |
| 7 | Remote sensing of earth’s energy budget:synthesis and review显示文摘The Earth’s climate is largely determined by its energy budget.Since the 1960s,satellite remote sensing has been used in estimating these energy budget components at both the top of the atmosphere(TOA)and the surface.Besides the broadband sensors that have been traditionally used for monitoring Earth’s Energy Budget(EEB),data from a variety of narrowband sensors aboard both polar-orbiting and geostationary satellites have also been extensively employed to estimate the EEB components.This paper provides a comprehensive review of the satellite missions,state-of-the art estimation algorithms and the satellite products,and also synthesizes current understanding of the EEB and spatiotemporal variations.The TOA components include total solar irradiance,reflected shortwave radiation/planetary albedo,outgoing longwave radiation,and energy imbalance.The surface components include incident solar radiation,shortwave albedo,shortwave net radiation,longwave downward and upwelling radiation,land and sea surface temperature,surface emissivity,all-wave net radiation,and sensible and latent heat fluxes.Some challenges,and outlook such as virtual constellation of different satellite sensors,temporal homogeneity tests of long time-series products,algorithms ensemble,and products intercomparison are also discussed. | Shunlin Liang Dongdong Wang Tao He Yunyue Yu | 2019 | International Journal of Digital Earth2019，12，7： | 5 |
| 8 | Vitamin D supplementation in pregnant women or infants for preventing allergic diseases:a systematic review and meta-analysis of randomized controlled trials显示文摘Background:It is still unclear if and to what extent antenatal or infant or childhood vitamin D supplementation would affect the development of allergy diseases later in life.This study aimed to review the efficacy of vitamin D supplementation in pregnant women,infants,or children for the prevention of allergies.Methods:MEDLINE(PubMed),EMBASE(OVID),and the Cochrane Central Register of Controlled Trials were searched up to March 1,2020.We included only randomized controlled trials(RCTs).We performed a systematic review and meta-analysis for vitamin D supplementation in primary allergy prevention.These trials were assessed for risk of bias using the Cochrane Collaboration domains and the consensus was reached via discussion with the full study group.We descriptively summarized and quantitatively synthesized original data to evaluate vitamin D supplementation in primary allergy prevention by using Review Manager software for meta-analysis.Results:The search yielded 1251 studies.Seven RCTs were included in this analysis.A meta-analysis revealed that vitamin D supplementation for pregnant women or infants may not decrease the risk of developing allergic diseases,such as asthma or wheezing(supplementation for pregnant women,risk ratio[RR]:1.01,95%confidence interval[CI]:0.81-1.26,P=0.90,I^(2)=47%;supplementation for infants,RR:1.00,95%CI:0.70-1.43,P=0.99,I2=0%;supplementation for pregnant women and infants,RR:0.35,95%CI:0.10-1.25,P=0.11),eczema(supplementation for pregnant women,RR:0.95,95%CI:0.80-1.13,P=0.77,I^(2)=0%;supplementation for infants,RR:0.84,95%CI:0.64-1.11,P=0.19,I2=42%),allergic rhinitis(supplementation for pregnant women,RR:0.93,95%CI:0.78-1.11,P=0.15,I^(2)=47%),lower respiratory tract infection(LRTI)(supplementation for pregnant women,RR:0.97,95%CI:0.85-1.11,P=0.59,I^(2)=0%),or food allergy.Conclusions:Supplementation of vitamin D in pregnant women or infants does not have an effect on the primary prevention of allergic diseases. | Chao Luo Yaning Sun Zuojing Zeng Ying Liu Shunlin Peng | 2022 | Chinese Medical Journal2022，，3： | 3 |
| 9 | Enhanced Adsorption of Pb(II) Ions from Aqueous Solution by Persimmon Tannin-activated Carbon Composites显示文摘The modification of activated carbon with persimmon tannin and its application for the removal of Pb(II) ions were carried out by batch method. The effects of solution pH, contact time, temperature and initial concentration on the immobilization of persimmon tannin were studied. The experimental results showed that the experimental data of persimmon tannin and Pb(II) fitted better by Langmuir adsorption isotherm model and pseudo-second order model. The adsorption capacities of adsorbents for persimmon tannin and Pb(II) were calculated from the Langmuir isotherm model, and found to be 42.97 and 12.40 mg/g at optimum pH, respectively. It was noted that the adsorbent exhibited the best adsorption property for Pb(II) when 1.0 g activated carbon was modified by 17.32 mg persimmon tannin. The modified activated carbon is more effective than the plain activated carbon, and it is expected to be an economic and effective adsorbent for the disposal of wastewater containing Pb(II) ions. | 王勇 王富忠 WAN Tao CHENG Shunlin XU Guoqing CAO Rui GAO Ming | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，4： | 3 |
| 10 | 中国淮安地区2009年至2011年恶性肿瘤的发病率及死亡率分析(英文)显示文摘Objective: The aim of the study was to investigate the cancer incidence and mortality in Huai'an area, China, from 2009 to 2011. Methods: The data about cancer incidence and mortality were provided by Huai'an Cancer Registry, China. In- cidence and mortality rates, and standardized rates were calculated by age, gender, areas (urban and rural areas of Huai'an) and cancer sites. Results: The crude incidence rate for all cancer sites was 205.60/10 5 and the standardized incidence rate was 166.22/10 5 . Both the crude and standardized rates were higher in urban area than in rural area for both sexes. The inci- dence rates increased in people aged 40 and over, and the peak ages of incidence were between 70-75 in both males and females. The crude mortality rate for all cancer sites was 153.88/10 5 and the standardized mortality rate was 122.14/10 5 . Both the crude and standardized rates were similar in urban and rural areas for both men and women. The mortality rates were at low level under the age 50 in both sexes, but increased after the age 50, reaching the peak at the ages of 80-85 in both males and females. The top 10 most common cancer sites in rank were esophagus, stomach, lung, liver, colon-rectum, breast, pancreas, cervix uteri, brain and central nervous system, and leukemia, accounting for 87.56% of all cancers. The top 10 most leading causes of cancer death in order were cancers of esophagus, lung, liver, stomach, colon-rectum, pancreas, brain and central nervous system, leukemia, breast and lymphoma, accounting for 90.53% of all cancer deaths. Conclusion: Cancer is one kind of major diseases threatening people's health in Huai'an area, China. Cancer prevention and control should be enhanced, especially for esophageal cancer. | Guangjin Yuan Qianwen Li Yunxiang Du Shunlin Shan Zhimin Wang Enchun Pan Yuan He Ting Wang | 2012 | The Chinese-German Journal of Clinical Oncology2012，11，9： | 3 |

| 13 | Swallowtail model for predicting the global bifurcation behavior of CO oxidation reactions显示文摘Catalytic CO oxidation on platinum group metals exhibits nonlinear phenomena such as hysteresis and bifurcation.Elucidation of the nonlinear mechanisms is important for catalyst design and control of reaction routes.Previous studies have offered initial insights into the local bifurcation behavior of CO oxidation.However,since the bifurcation behavior of CO oxidation is determined by multiple parameters such as temperature,total flux,and CO fraction,it is difficult to predict the global bifurcation behavior in the resulting high-dimensional parameter space.It is for this reason that the observed nonlinear phenomena reflect just the local bifurcation features of CO oxidation.In this paper,an elementary chemical law(topological invariance) concerning the bifurcation behavior of CO oxidation on platinum group metals such as Pd(111) is found from a topological perspective.Following the elementary law,we put forward a topological approach to model the critical criteria for the reaction hysteresis and bifurcation.The model may be applied to predict the global bifurcation behavior of CO oxidation in the high-dimensional parameter space.The topological approach and the model results may be useful as a guide in thinking about the complex reaction mechanism,designing reaction routes,and actively controlling the bifurcation behavior of the CO oxidation reaction. | CUI Tao TANG ShunLin ZHANG Lei YU DaRen | 2011 | Science China Chemistry2011，54，7： | 2 |
| 14 | Improvement of cardiac function by hepatocyte growth factor via intracoronary transfection in the swine myocardial infarction model显示文摘Objective:To study the amelioration effect of Adenovirus5-mediated human hepatocyte growth factor(Ad5-HGF)on postinfarction heart failure in the swine myocardial infarction model.Methods:Twelve SuZhong young swine were randomly divided into 2 groups with 6 swine in each group:Ad5-HGF-treated group and null-Ad5 group.Four weeks after ligation at left anterior descending coronary artery in swine hearts,Ad5-HGF was transferred to the swine myocardium.Simultaneously,Gated myocardial perfusion imaging was performed to evaluate cardiac perfusion and heart function.After three weeks,Gated myocardial perfusion imaging was performed again,then the hearts were harvested and sectioned to examine the expression of HGF through ELISA.Results:High expression of human HGF was observed in the myocardium of Ad5-HGF-treated group.From 4 weeks to 7 weeks after operation,Left ventricular ejection fraction was increased in Ad5-HGF-treated group.The improvement in LVEF was greater in Ad5-HGF-treated group than that in null-Ad5 group at 7 weeks after operation.Cardiac perfusion was significantly improved in the Ad5-HGF-treated group.Conclusion:High expression of human HGF was observed in the myocardium through intracoronary transfection,which suggests that HGF can ameliorate heart function in swine with postinfarction heart failure. | Wei Wang Zhijian Yang Dongchao Ma Shunlin Xu Yourong Zhang Yuqing Zhang Liansheng Wang Bo Chen Kejiang Cao Wenzhu Ma | 2006 | Journal of Nanjing Medical University2006，20，4： | 2 |
