| 1 | 高光谱遥感在农作物长势监测中的应用显示文摘该研究是加拿大Saskatchewan Scott农作物轮作系统(ACS)研究的一部分。研究始于1994年,历时18a,评价9个可耕种农作物产量系统的可靠性。由3种处理水平(organic,reduced,high)和3种作物多样性水平(low,diversified annual grains,diversified annual perennials)结合而产生的9个农作物产量系统,被用于监测和评价加拿大牧场不同处理和不同作物种植轮作下可耕种农作物的产量。在2003年生长季共收集了3次叶面积指数和光谱反射率的数据:生长季前期(6月)、生长季旺盛期(7月)、生长季后期(8月)。叶面积指数是由LAI-2000植物冠层分析仪监测的,光谱测量是由覆盖了350-2500 nm波长范围共2215个波段的ADS便携式高光谱仪完成的。结果显示,光学测量可以用于监测农作物生长状况的差异。从生长季的早期到中期,光谱和叶面积指数在不同处理下有显著差异。7月中期是用遥感资料监测农作物长势的最佳季节;红光波段与近红外波段反射率的比值和基于这两个波段构造的归一化植被指数,是检测农作物长势的最佳植被指数。 | 郑有飞 Guo X Olfert O Brandt S Thomas G Weiss R Sproule L | 2007 | 气象与环境科学2007,30,1: | 22 |
| 2 | Identification of meta-instable stress state based on experimental study of evolution of the temperature field during stick-slip instability on a 5° bending fault显示文摘Identification of the meta-instable stress state and study of its mechanism and evolution of relevant physical fields would be of great significance for determination of potential seismic risks and estimation of critical times. In laboratory experiments, that the specimen enters the meta-instable is marked by accelerated stress release. Could we use the experimental result to identify the earthquake in natural conditions? Because the observational data from one station can only reflect the stress state beneath this station, the key problem for identification of the meta-instability is how to recognize regional stress state through observational data from many stations. In this work, we choose the evolution of the temperature field over varied deformation stages during a stick-slip event on a 5 bending fault as an example, and attempt to find the response features of the physical quantity when the fault enters the meta-instable state. We discuss the characteristics of stages for the stress build-up, stress-time process deviating from linearity before instability, meta-instability, instability, and post-instability, respectively. The result shows that the fault instability slide is a conversion process from independent activities of each fault segment to synergism activity. The instability implies completion of the synergism. The stage deviating from linearity is the onset of stress release, and it is also the onset of the synergism. At the meta-instability stages, stress release becomes dominant, while the synergism tends to finish. Therefore, the analysis of the regional overall stress state should not start from individual stations, and instead it should begin with the evolution of the whole deformation field. | MA Jin S I SHERMAN GUO YanShuang | 2012 | Science China Earth Sciences2012,55,6: | 22 |

| 4 | Percutaneous transhepatic metal versus plastic biliary stent in treating malignant biliary obstruction: a multiple center investigation显示文摘OBJECTIVE: To compare the efficacy of metal versus plastic biliary stent implantation in the treatmentof malignant biliary obstruction.METHODS: Percutaneous transhepatic self-expandable metal stent (MS, n=61) and 10F plastic stent(PS, n=34) were placed in 95 patients with malignant biliary obstruction in three hospitals of Guangdongprovince. All patients were followed up until death or at least one year after the procedure. Kaplan-Meieranalysis was used to compare the survival of the patients and the rates of stent patency.RESULTS: The 30-day mortality rate was lower in the MS group (6/61, 9.8%) than in the PS group(9/34, 26.5%, P<0.05). The 30-day reobstruction rate and the complication rate were 15.0%, 16.4%in the MS group and 32. 4%, 29. 4% in the PS group, respectively (P<0. 01). The median patencyperiod of stents and median survival period of the patients were 230 days, 224 days in the MS group and90 days, 94 days in the PS group, respectively (P<0. 01).CONCLUSION: Metal stent is clinically superior to plastic stent in the treatment of malignant biliaryobstruction. | Yuan-Xing Guo Yan-Hao Li Yong Chen Ping-Yan Chen Peng-Fei Luo Yong Li Hong Shan Zai-Bo Jiang the Department of Interventional Radiology, Nanfang Hospital, First Military Medical University, Guangzhou 510515, China Department of Medical Statistics, First Military Medical University, Guangzhou 510515, China Department of Radiology, Guangdong Provincial People’s Hospital, Guangzhou 510080, China Department of Radiology, Third Affiliated Hospital of Sun Yat-Sen University of Medical Sciences, Guangzhou 510630, China | 2003 | Hepatobiliary & Pancreatic Diseases International2003,2,4: | 8 |
| 5 | Establishment and evaluation of the system of extracorporeal liver perfusion in pigs显示文摘BACKGROUND; In recent years, extracorporeal liver per- fusion (ECLP) has been regarded as a treatment of acute liver failure ( ALF ); but the system of ECLP has many problems. The purpose of this experiment was to detect the factors affecting the system of ECLP and to establish a sta- ble and effective system of ECLP. METHODS; Livers were harvested from health pigs, ac- cording to the different styles of perfusion and oxygena- tion, which were randomly divided into 3 groups. The liv- ers in group A (n =4) were subjected to single portal vein perfusion, oxygenating perfusion blood; the livers in group B (n =4) to dual ( portal vein and hepatic artery) vessel perfusion, oxygenating blood, together; and the livers in group C ( n = 4) to dual (portal vein and hepatic artery) vessel perfusion, but oxygenating blood, separately. The perfusion time, the data of bile production, and hemody- namic parameters of extracorporeal livers in each group were tested. The histological examination of liver tissues from each group was performed at the end of perfusion. RESULTS: The perfusion time of the liver in group A is significantly shorter than in groups B and C (P<0.05). At 1 , 3 , 6 hours after perfusion, the data of bile production and hemodynamic parameters of livers in group A were sta- tistically different from those of livers in groups B and C (P<0.05). At 1, 3, 6 hours after perfusion, the data of group B were not statistically different from those of livers in group C (P>0.05). But at 12 hours after perfusion, the data of group B were statistically different from those of liv- ers in group C (P<0.01). CONCLUSION: The system of ECLP, which is performed by dual ( portal vein and hepatic artery) vessel perfusionand oxygenating blood separately, is more stable and effec- tive to keep the function of extracorporeal liver. | Jin Gong, Xi-Mo Wang, Gang Long, Zhong-Tao Guo, Tao Jiang and Shi Chen Wuhan, ChinaInstitute of Organ Transplantation, Tongji Hospital, Tongji Medical College , Huazhong University of Science and Technology, Wuhan 430030, China Department of Surgery, Tianjin People’s Hospital, Tianjin 300120, China | 2005 | Hepatobiliary & Pancreatic Diseases International2005,4,1: | 7 |
| 6 | 大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。 | 孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini | 2021 | 英国医学杂志中文版2021,24,8: | 7 |
| 7 | The magnetic properties of Serbian loess and its environmental significance显示文摘This paper reports a loess-paleosol sequence located in the Danube River basin,Serbia,which formed at least since the latest part of the early Pleistocene,and before the paleomagnetic B/M boundary.Various magnetic parameters of the Serbian V-L1-V-S4 loess-paleosol sequence have been measured and analyzed in the Titel Loess Plateau.These parameters show a very similar magnetic behavior compared with that of the Chinese loess.There is a general positive relationship between magnetic susceptibility() and pedogenesis.The main contributors to are the magnetic grains of SP(superparamagnetic) and SD(single domain) magnetic domains,while MD(multi domain) contributes only a small percentage.The difference in between loess and paleosol mainly is caused by pedogenesis.The very fine magnetic minerals increase gradually with increasing soil development(from loess to soil),and they lead to higher.The thermomagnetic curves show thatmagnetic minerals in the loess layers are magnetite and maghemite,both providing a major contribution to.In contrast the paleosol layers mainly are composed of magnetite,with almost no or a very small amount of maghemite,as implied by a reversible thermomagnetic behavior.This indicates that pedogenic conditions during V-S3 and V-S4 strong soil development have resulted in maghemite that is no longer stable,and has been resolved or converted to other stable phase minerals.This likely indicates that soil moisture during V-S3 and V-S4 development exceeded a critical condition of maghemite stability. | LIU XiuMing LIU Zhi Lü Bin MARKOVI S B CHEN JiaSheng GUO Hui MA MingMing ZHAO GuoYong FENG Hua | 2013 | Chinese Science Bulletin2013,58,3: | 7 |

| 12 | Joining Performance and Microstructure of the 2024/7075 Aluminium Alloys Welded Joints by Vaporizing Foil Actuator Welding显示文摘Vaporizing foil actuator welding(VFAW) was used for joining 2024-T3 and 7075-T6 aluminum alloy sheets, and the resulting joint microstructure was analyzed. 2024/7075 aluminum alloy pairs with suitable processing parameters can be prepared by using VFAW. Dynamic preform addresses the poor formability problem of target material and advantage of VFAW on dissimilar materials in some conditions. But with standoff sheet inserting in the flyer and target, 2024/7075 welded pairs gets the better weld strength, compared with flyer preformed method. The microstructure of the circular weld area of the welded joint showed a wave interface, in which a thin melt layer formed at the center and edge parts. The crystal grains near the bonding interface were remarkably elongated and refined. Therefore, the joining of the 2024/7075 pairs was facilitated through plastic forming and melting. | 孟正华 WANG Xu GUO Wei HU Zhili Anupam Vivek HUA Lin Glenn S DAEHN | 2019 | Journal of Wuhan University of Technology(Materials Science)2019,34,2: | 4 |

| 14 | Thermodynamic Analysis of Desulfurization and Its Connection With Deoxidation and Temperature for SPHC in JISC During LF Refining Process显示文摘The thermodynamic characteristics of desulfurization reaction (CaO)+[S]=(CaS)+[O] is analyzed based on the detailed composition of liquid steel and slag of Steel Plate Hot Commercial (SPHC) in Jiuquan Iron & Steel Corporation(JISC), where the activities of CaO, CaS and Al2O3 in molten slag are calculated by thermodynamic software FactSage for a more accurate result. The critical values of [O%]/[S%] for desulfurization at different temperature is are obtained, typically 0.09 at 1873K, which shows directly that it should deoxidize adequately for obtaining a favorable desulfurization condition. In addition, the thermodynamic analysis indicates that the actual dissolved O is much higher than that of equilibrium calculation which shows Al-O reaction in LF is far away from equilibrium, but it is perfect agreement with the computing results when taking the activity of Al2O3 as 1 that due to the inclusion component in LF is mainly Al2O3. Besides, with the temperature rise, the sulfur partition ratio increases softly meanwhile the reaction between Al and O is limited to a great degree resulting in the increase a dissolved oxygen in liquid steel that decreases the sulfur partition ratio seriously. As a result, the sulfur partition ratio appears to decrease with temperature increase in Al killed steel. | GUO Jing1, CHENG Zi-jian1,2, CHENG Shu-sen1, CHENG Ze-wei1, ZOU Ming2, MA Ming-sheng2 (1.

| 15 | Zeus robot-assisted laparoscopic cholecystectomy in comparison with conventional laparoscopic cholecystectomy显示文摘BACKGROUND: The robotic surgical system overcomes many technological obstacles of conventional laparoscopic surgery, and possesses enormous clinical applied potential. The aim of this study was to compare the efficacy of Zeus robot-assisted laparoscopic cholecystectomy with conventional laparoscopic cholecystectomy. METHODS: Forty patients undergoing elective cholecystectomy were randomly divided into two groups. Patients in group A (n=20) underwent Zeus robot-assisted laparoscopic cholecystectomy, and patients in group B (n=20) received conventional laparoscopic cholecystectomy. The parameters on operative field, operative time, the number of actions, the rate of operative errors and minimal trauma were evaluated and compared between the two groups. RESULTS: The number of cleating camera (1.1±1.0 times) and the time of adjusting the operative field (2.2±0.7 minutes) in group A were significantly less than those (4.5±1.5 times) and (7.5±1.2 minutes) in group B. The number of dissection actions (337±86 times) and the rate of operative errors (10%) in group A were less than those (389±94 times), (25%) in group B. The total operation time (104.9±20.5 minutes) and setup time (29.5±9.8 minutes) in group A were significandy longer than those (78.6±17.1 minutes), (12.6±2.5 minutes) in group B. Blood loss and postoperative hospitalization were similar. No postoperative complications occurred in both groups, and open cholecystectomy was performed in each group. CONCLUSIONS: Zeus robot-assisted cholecystectomy inherits the benefits of minimally invasive surgery. The Zeus robotic surgical system is better than conventional laparoscopic technique in controlling the operative field and can be manipulated precisely and stablely though it requires more operative time. | Han-Xin Zhou, Yue-Hua Guo, Xiao-Fang Yu, Shi-Yun Bao, Jia-Lin Liu, Yue Zhang and Yong-Gong Ren Department of Minimally Invasive Surgery, Shenzhen People’s Hospital, Jinan University 2nd Clinical Medicine College, Shenzhen 518020.

| 16 | Promising xenograft animal model recapitulating the features of human pancreatic cancer显示文摘BACKGROUND Multiple sites of metastasis and desmoplastic reactions in the stroma are key features of human pancreatic cancer(PC).There are currently no simple and reliable animal models that can mimic these features for accurate disease modeling.AIM To create a new xenograft animal model that can faithfully recapitulate the features of human PC.METHODS Interleukin 2 receptor subunit gamma(IL2RG)gene knockout Syrian hamster was created and characterized.A panel of human PC cell lines were transplanted into IL2RG knockout Syrian hamsters and severe immune-deficient mice subcutaneously or orthotopically.Tumor growth,local invasion,remote organ metastasis,histopathology,and molecular alterations of tumor cells and stroma were compared over time.RESULTS The Syrian hamster with IL2RG gene knockout(named ZZU001)demonstrated an immune-deficient phenotype and function.ZZU001 hamsters faithfully recapitulated most features of human PC,in particular,they developed metastasis at multiple sites.PC tissues derived from ZZU001 hamsters displayed desmoplastic reactions in the stroma and epithelial to mesenchymal transition phenotypes,whereas PC tissues derived from immune-deficient mice did not present such features.CONCLUSION ZZU001 hamsters engrafted with human PC cells are a superior animal model compared to immune-deficient mice.ZZU001 hamsters can be a valuable animal model for better understanding the molecular mechanism of tumorigenesis and metastasis and the evaluation of new drugs targeting human PC. | Jin-Xin Miao Jian-Yao Wang Hao-Ze Li Hao-Ran Guo Louisa S Chard Dunmall Zhong-Xian Zhang Zhen-Guo Cheng Dong-Ling Gao Jian-Zeng Dong Zhong-De Wang Yao-He Wang | 2020 | World Journal of Gastroenterology2020,26,32: | 3 |
| 17 | Global Wheat Head Detection 2021:An Improved Dataset for Benchmarking Wheat Head Detection Methods显示文摘The Global Wheat Head Detection(GWHD)dataset was created in 2020 and has assembled 193,634 labelled wheat heads from 4700 RGB images acquired from various acquisition platforms and 7 countries/institutions.With an associated competition hosted in Kaggle,GWHD_2020 has successfully attracted attention from both the computer vision and agricultural science communities.From this first experience,a few avenues for improvements have been identified regarding data size,head diversity,and label reliability.To address these issues,the 2020 dataset has been reexamined,relabeled,and complemented by adding 1722 images from 5 additional countries,allowing for 81,553 additional wheat heads.We now release in 2021 a new version of the Global Wheat Head Detection dataset,which is bigger,more diverse,and less noisy than the GWHD_2020 version. | Etienne David Mario Serouart Daniel Smith Simon Madec Kaaviya Velumani Shouyang Liu Xu Wang Francisco Pinto Shahameh Shafiee Izzat SATahir Hisashi Tsujimoto Shuhei Nasuda Bangyou Zheng Norbert Kirchgessner Helge Aasen Andreas Hund Pouria Sadhegi-Tehran Koichi Nagasawa Goro Ishikawa Sébastien Dandrifosse Alexis Carlier Benjamin Dumont Benoit Mercatoris Byron Evers Ken Kuroki Haozhou Wang Masanori Ishii Minhajul ABadhon Curtis Pozniak David Shaner LeBauer Morten Lillemo Jesse Poland Scott Chapman Benoit de Solan Frédéric Baret Ian Stavness Wei Guo | 2021 | Plant Phenomics2021,3,1: | 2 |

| 19 | Development of an educational cartoon to prevent worm infections in Chinese schoolchildren显示文摘Background:With more than two billion people infected worldwide,soil-transmitted helminths(STH)are the most widespread infections.To date,STH control efforts rely predominantly on recurrent mass drug administration(MDA),which does not prevent reinfection.Additional public health measures including novel health educational tools are required for more sustained integrated control of STH.We describe the development of an educational cartoon video(The Magic Glasses)targeting STH infections in Chinese schoolchildren and its pilot testing in China.We applied an extensive community-based mixed methods approach involving input from the target group of 9–10 year old schoolchildren and key informants,such as teachers,doctors and parents,in order to identify potential STH infection risks in the study area and to formulate key messages for the cartoon.The development of the educational cartoon included three major steps:formative research,production,and pilot testing and revision.Results:We found that most adults and approximately 50%of the schoolchildren were aware of roundworm(Ascaris)infection,but knowledge of transmission,prevention and treatment of STH was poor.Observations in the study area showed that unhygienic food practices,such as eating raw and unwashed fruit or playing in vegetable gardens previously fertilised with human faeces,posed major STH infection risks.Conclusions:It was crucial to assess the intellectual,emotional,social and cultural background of the target population prior to video production in order to integrate the key messages of the cartoon into everyday situations.Overall,our strategy for the development of the cartoon and its incorporation into a health education package proved successful,and we provide a summary of recommendations for the development of future educational videos based on our experiences in China. | Franziska A Bieri Li-Ping Yuan Yue-Sheng Li Yong-Kang He Andrew Bedford Robert S Li Feng-Ying Guo Sheng-Ming Li Gail M Williams Donald P McManus Giovanna Raso Darren J Gray | 2013 | Infectious Diseases of Poverty2013,2,1: | 2 |
