| 1 | 交易费用与农户契约选择--来自浙冀两省15县30个村梨农调查的经验证据显示文摘本文利用327份入户调查数据,依据已有的理论研究成果及经验研究证据,首先采用数据包络分析方法(DEA)测算农户生产阶段和销售阶段的技术效率,在此基础上做出交易费用是影响农户选择不同契约模式的重要因素这一基础假定,建立计量模型并运用Multi-nomial Logit回归方法进行验证。研究结果显示:农户销售阶段技术效率普遍偏低,均低于生产技术效率,但不同销售渠道的技术效率有显著差异。相对于最为传统的农户自行零售方式而言,以信息成本、谈判成本和执行成本为代表的交易成本对农户选择不同的契约方式有显著的影响,农户特征对选择不同的交易渠道影响不显著。在农产品市场体制建立和完善的过程中,为逐步解决传统农产品的卖难问题,决策部门可以适度考虑农户的信息需求以降低农户的信息搜寻成本;提高农民的组织化程度以增强农户的谈判能力和提升产品质量水平;鼓励电子商务等现代化的交易手段以降低交易的执行成本;改善道路交通条件以降低农户实际承担的交通成本。 | 黄祖辉 张静 Kevin Chen | 2008 | 管理世界2008，24，9： | 85 |
| 2 | 金融发展与地区实体经济资本配置效率——来自省级工业行业数据的证据显示文摘本文基于实体经济运行的视角主要探讨了金融系统是否发挥了改善我国地区实体经济资本配置效率的功能。文章以1999—2006年间中国30个地区27个工业行业为样本,借助Wur-gler(2000)的资本配置效率估算模型,构建了非国有部门信贷比重等衡量金融发展程度的指标,并运用系统广义矩面板估计方法等进行实证检验。结果显示:金融发展促进了中国地区实体经济资本配置效率的提高,同时当进一步考虑地方政府对银行信贷决策干预的影响时,地方政府的干预却会妨碍金融系统对中国地区实体经济资本配置效率改善功能的有效发挥。 | 李青原 李江冰 江春 Kevin X.D.Huang | 2013 | 经济学(季刊)2013，12，1： | 273 |

| 4 | Nano-Graphene Oxide for Cellular Imaging and Drug Delivery显示文摘Two-dimensional graphene offers interesting electronic,thermal,and mechanical properties that are currently being explored for advanced electronics,membranes,and composites.Here we synthesize and explore the biological applications of nano-graphene oxide(NGO),i.e.,single-layer graphene oxide sheets down to a few nanometers in lateral width.We develop functionalization chemistry in order to impart solubility and compatibility of NGO in biological environments.We obtain size separated pegylated NGO sheets that are soluble in buffers and serum without agglomeration.The NGO sheets are found to be photoluminescent in the visible and infrared regions.The intrinsic photoluminescence(PL)of NGO is used for live cell imaging in the near-infrared(NIR)with little background.We found that simple physisorption viaπ-stacking can be used for loading doxorubicin,a widely used cancer drug onto NGO functionalized with antibody for selective killing of cancer cells in vitro.Owing to its small size,intrinsic optical properties,large specifi c surface area,low cost,and useful non-covalent interactions with aromatic drug molecules,NGO is a promising new material for biological and medical applications. | Xiaoming Sun Zhuang Liu Kevin Welsher Joshua Tucker Robinson Andrew Goodwin Sasa Zaric Hongjie Dai | 2008 | Nano Research2008，1，3： | 118 |
| 5 | 氯吡格雷的使用与药物洗脱支架植入后远期临床结果显示文摘背景:近来的冠状动脉内药物洗脱支架研究提示,现行的抗血小板治疗方案可能并不足以预防后期支架内血栓形成。目的:于接受药物洗脱支架(drug-eluting stents,DESs)和裸金属支架(bare-metal stents,BMSs)治疗的冠状动脉病患者中评估氯吡格雷使用与患者远期结果的关系。设计、地点及患者:于连续患者中进行观察性研究。患者于2000年1月1日至2005年7月31日在杜克心脏治疗中心(一家位于北卡罗来纳州达累姆市的三级治疗中心)接受冠状动脉内支架治疗。于6、12、24个月时进行随访,直至2006年9月7日。研究人群包括4666例最初接受BMS(n=3165)或DES(n=1501)经皮冠状动脉介入治疗的患者。对随访6和12个月没有事件(没有死亡、心肌梗死或血管重建手术)的患者进行界标分析(landmark analysis)。在这些时间点上根据支架类型以及自我报告之氯吡格雷的使用情况将患者分为4组:DES使用氯吡格雷组、DES不用氯吡格雷组、BMS使用氯吡格雷组以及BMS不用氯吡格雷组。主要观测指标:随访24个月时死亡、非致命性心肌梗死以及死亡或心肌梗死之复合终点。结果:在6个月时没有事件发生的DES组患者(637例使用、579例未使用氯吡格雷)中,氯吡格雷的使用是随访24个月校正死亡率较低(使用2.0%比未使用5.3%;差异,-3.3%;95%CI,-6.3%至-0.3%;P=0.03)以及死亡或心肌梗死发生率较低(3.1%比7.2%;差异,-4.1%;95%CI,-7.6%至-0.6%;P=0.02)的显著预测指标。然而,在BMS组患者中(417例使用、1976例未用氯吡格雷),死亡(3.7%比4.5%;差异,-0.7%;95%CI,-2.9%至1.4%;P=0.50)以及死亡或心肌梗死发生率(5.5%比6.0%;差异,-0.5%;95%CI,-3.2%至2.2%;P:0.70)没有差异。在12个月随访没有事件发生的DES组患者(252例使用、276例未用氯吡格雷)中,氯吡格雷的使用依然可以预测24个月死亡(0%比3.5%;差异,-3.5%;95%CI,-5.9%至-1.1%;P=0.004)以及死亡或心肌梗死发生率(0%比4.5%;差异,-4.5%;95%CI,-7.1%至-1.9%;P〈0.001)较低。然而,在BMS组患者中(346例使用、1644例未用氯吡格雷),在死亡(3.3%比2.7%;差异,0.6%;95%CI,1.5%至2.8%;P=0.57)以及死亡或心肌梗死(4.7%比3.6%;差异,1.0%;95%CI,-1.6%至3.6%;P=0.44)发生方面,依然没有差异。结论:在接受DES治疗的患者中,延长氯吡格雷的使用可以使死亡以及死亡或心肌梗死的发生率下降。然而,使用氯吡格雷的适宜期限只能通过大型临床随机试验确定。 | Eric L Eisenstein, DBA Kevin J.

| 6 | Carbon Nanotubes in Biology and Medicine:In vitro and in vivo Detection,Imaging and Drug Delivery显示文摘Carbon nanotubes exhibit many unique intrinsic physical and chemical properties and have been intensively explored for biological and biomedical applications in the past few years.In this comprehensive review,we summarize the main results from our and other groups in this field and clarify that surface functionalization is critical to the behavior of carbon nanotubes in biological systems.Ultrasensitive detection of biological species with carbon nanotubes can be realized after surface passivation to inhibit the non-specific binding of biomolecules on the hydrophobic nanotube surface.Electrical nanosensors based on nanotubes provide a label-free approach to biological detection.Surface-enhanced Raman spectroscopy of carbon nanotubes opens up a method of protein microarray with detection sensitivity down to 1 fmol/L.In vitro and in vivo toxicity studies reveal that highly water soluble and serum stable nanotubes are biocompatible,nontoxic,and potentially useful for biomedical applications.In vivo biodistributions vary with the functionalization and possibly also size of nanotubes,with a tendency to accumulate in the reticuloendothelial system(RES),including the liver and spleen,after intravenous administration.If well functionalized,nanotubes may be excreted mainly through the biliary pathway in feces.Carbon nanotube-based drug delivery has shown promise in various In vitro and in vivo experiments including delivery of small interfering RNA(siRNA),paclitaxel and doxorubicin.Moreover,single-walled carbon nanotubes with various interesting intrinsic optical properties have been used as novel photoluminescence,Raman,and photoacoustic contrast agents for imaging of cells and animals.Further multidisciplinary explorations in this field may bring new opportunities in the realm of biomedicine. | Zhuang Liu Scott Tabakman Kevin Welsher Hongjie Dai | 2009 | Nano Research2009，2，2： | 50 |

| 8 | 新疆B型烟粉虱对不同类型杀虫剂的抗性与分析显示文摘应用浸叶法研究了新疆B型烟粉虱对4类不同作用机制杀虫剂的抗药性。结果表明,被测种群对氯氰菊酯和联苯菊酯的抗性指数分别为2100~6200和1000~2200,属于高抗性;对氯化烟酰类杀虫剂产生了低至中等抗性,对吡虫啉的抗性指数为4~86,且抗性指数呈上升趋势,对噻虫嗪的抗性指数为10~22,对啶虫脒的敏感性最佳;对昆虫生长调节剂吡丙醚的抗性指数为22~54;对阿维菌素仍然表现敏感。由此认为,拟除虫菊酯类杀虫剂在新疆已不再适用于烟粉虱的防治,而对受抗药性影响较小的氯化烟酰类杀虫剂(如吡虫啉、噻虫嗪和啶虫脒)、昆虫生长调节剂吡丙醚以及阿维菌素等新型杀虫剂,仍然可以限制性地在不同化合物间交替使用。 | 马德英 Ian Denholm Kevin Gorman 罗万春 | 2007 | 植物保护学报2007，34，3： | 31 |
| 9 | Chronic hepatitis B infection in pregnancy显示文摘There are no standard guidelines to follow when a patient with chronic hepatitis B infection becomes pregnant or desires pregnancy. Topics to consider include which patients to treat, when to start treatment, what treatment to use and when to stop treatment. Without any prophylaxis or antiviral therapy, a hepatitis B surface antigen and E antigen positive mother has up to a 90% likelihood of vertical transmission of hepatitis B virus(HBV) to child. Standard of care in the United States to prevent perinatal transmission consists of administration of hepatitis B immune globulin and HBV vaccination to the infant. The two strongest risk factors of mother to child transmission(MTCT) of HBV infection despite immunoprophylaxis are high maternal HBV viral load and high activity of viral replication. The goal is to prevent transmission of HBV at birth by decreasing viral load and/or decreasing activity of the virus. Although it is still somewhat controversial, most evidence shows that starting antivirals in the third trimester is effective in decreasing MTCT without affecting fetal development. There is a growing body of literature supporting the safety and efficacy of antiviral therapies to reduce MTCT of hepatitis B. There are no formal recommendations regarding which agent to choose. Tenofovir, lamivudine and telbivudine have all been proven efficacious in decreasing viral load at birth without known birth defects, but final decision of which antiviral medication to use will have to be determined by physician and patient. The antivirals may be discontinued immediately if patient is breastfeeding, or within first four weeks if infant is being formula fed. | Jennifer R Lamberth Sheila C Reddy Jen-Jung Pan Kevin J Dasher | 2015 | World Journal of Hepatology2015，7，9： | 32 |
| 10 | New Trends in Olefin Production显示文摘Most olefins (e.g., ethylene and propylene) will continue to be produced through steam cracking (SC) ofhydrocarbons in the coming decade. In an uncertain commodity market, the chemical industry is investingvery little in alternative technologies and feedstocks because of their current lack of economic viability,despite decreasing crude oil reserves and the recognition of global warming. In this perspective, some of themost promising alternatives are compared with the conventional SC process, and the major bottlenecks ofeach of the competing processes are highlighted. These technologies emerge especially from the abundanceof cheap propane, ethane, and methane from shale gas and stranded gas. From an economic point of view,methane is an interesting starting material, if chemicals can be produced from it. The huge availability ofcrude oil and the expected substantial decline in the demand for fuels imply that the future for proventechnologies such as Fischer-Tropsch synthesis (FFS) or methanol to gasoline is not bright. The abundance ofcheap ethane and the large availability of crude oil, on the other hand, have caused the SC industry to shiftto these two extremes, making room for the on-purpose production of light olefins, such as by the catalyticdehydrogenation of orooane. | Ismael Amghizar Laurien A.

| 12 | Conceptualizing and Measuring Economic Resilience of Resource-based Cities: Case Study of Northeast China显示文摘This paper develops a conceptual model and an indicator system for measuring economic resilience of resource-based cities based on the theory of evolutionary resilience and the related concepts of persistence, adaptation, and transformation. Nineteen resource-based cities in Northeast China were analyzed using the indicator system. The results showed that Liaoning and Jilin provinces had higher economic resilience than Heilongjiang Province. Panjin, Benxi, and Anshan in Liaoning Province were the top three cities, while Shuangyashan and other coal-based cities in Heilongjiang Province ranked last. Metals-and petroleum-based cities had significantly higher resilience than coal-based cities. The differences in persistence, adaptability, transformation, and resilience among resource-based cities decreased since the introduction of the Northeast Revitalization Strategy in 2003. Forestry-based cities improved the most in terms of resilience, followed by metals-based and multiple-resource cities; however, resilience dropped for coal-based cities, and petroleum-based cities falling the most. The findings illustrate the importance and the way to develop a differentiated approach to improve resilience among resource-based cities. | TAN Juntao ZHANG Pingyu LO Kevin LI Jing LIU Shiwei | 2017 | Chinese Geographical Science2017，27，3： | 27 |
| 13 | high-entropy silicide:(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2)显示文摘A high-entropy metal disilicide,(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2),has been successfully synthesized.X-ray diffraction(XRD),energy dispersive X-ray spectroscopy(EDX),and electron backscatter diffraction(EBSD)collectively show the formation of a single high-entropy silicide phase.This high-entropy(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2) possesses a hexagonal C40 crystal structure with ABC stacking sequence and a space group of P6222.This discovery expands the known families of high-entropy materials from metals,oxides,borides,carbides,and nitrides to a silicide,for the first time to our knowledge,as well as demonstrating that a new,non-cubic,crystal structure(with lower symmetry)can be made into highentropy phase.This(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2) exhibits high nanohardness of 16.7±1.9 GPa and Vickers hardness of 11.6±0.5 GPa.Moreover,it has a low thermal conductivity of 6.9±1.1Wm^(-1) K^(-1),which is approximately one order of magnitude lower than that of the widely-used tetragonal MoSi_(2) and ~1/3 of those reported values for the hexagonal NbSi_(2) and TaSi_(2) with the same crystal structure. | Joshua Gild Jeffrey Braun Kevin Kaufmann Eduardo Marin Tyler Harrington Patrick Hopkins Kenneth Vecchio Jian Luo | 2019 | Journal of Materiomics2019，5，3： | 27 |
| 14 | Coarctation of the aorta:Management from infancy to adulthood显示文摘Coarctation of the aorta is a relatively common form of congenital heart disease, with an estimated incidence of approximately 3 cases per 10000 births. Coarctation is a heterogeneous lesion which may present across all age ranges, with varying clinical symptoms, in isolation, or in association with other cardiac defects. The first surgical repair of aortic coarctation was described in 1944, and since that time, several other surgical techniques have been developed and modified. Additionally, transcatheter balloon angioplasty and endovascular stent placement offer less invasive approaches for the treatment of coarctation of the aorta for some patients. While overall morbidity and mortality rates are low for patients undergoing intervention for coarctation, both surgical and transcatheter interventions are not free from adverse outcomes. Therefore, patients must be followed closely over their lifetime for complications such as recoarctation, aortic aneurysm, persistent hypertension, and changes in any associated cardiac defects. Considerable effort has been expended investigating the utility and outcomes of various treatment approaches for aortic coarctation, which are heavily influenced by a patient's anatomy, size, age, and clinical course. Here we review indications for intervention, describe and compare surgical and transcatheter techniques for management of coarctation, and explore the associated outcomes in both children and adults. | Rachel D Torok Michael J Campbell Gregory A Fleming Kevin D Hill | 2015 | World Journal of Cardiology2015，7，11： | 27 |
| 15 | Determination of contact parameters for discrete element method simulations of granular systems显示文摘Both linear-spring-dashpot (LSD) and non-linear Hertzian-spring-dashpot (HSD) contact models are commonly used for the calculation of contact forces in Discrete Element Method (DEM) simulations of granular systems. Despite the popularity of these models, determination of suitable values for the contact parameters of the simulated particles such as stiffness, damping coefficient, coefficient of restitution, and simulation time step, is not altogether obvious. In this work the relationships between these contact parameters for a model system where a particle impacts on a flat base are examined. Recommendations are made concerning the determination of these contact parameters for use in DEM simulations. | Kevin Francis Malone | 2008 | Particuology2008，6，6： | 23 |

| 17 | Helicobacter pylori associated gastric intestinal metaplasia:Treatment and surveillance显示文摘Gastric cancer(GC) is one of the leading causes of cancer related death in the world, particularly in East Asia. According to the Correa's cancer cascade, noncardia GC is usually developed through a series of mucosal changes from non-atrophic gastritis to atrophic gastritis(AG), intestinal metaplasia(IM), dysplasia and adenocarcinoma. Atrophic gastritis and IM are therefore generally considered to be pre-neoplastic gastric lesions. Helicobacter pylori(H. pylori) infection is an important initiating and promoting step of this gastric carcinogenesis cascade. Emerging long-term data showed that eradication of H. pylori reduced the risk of subsequent cancer development. It however remains confusing whether eradication of the bacterium in individuals with pre-neoplastic gastric lesions could regress these changes as well as in preventing cancer. Whilst H. pylori eradication could likely regress AG, the presence of IM may be a point of no return in this cascade. Hence, surveillance by endoscopy may be indicated in those with extensive IM or those with incomplete IM, particularly in populations with high GC risk. The optimal interval and the best tool of surveillance endoscopy remains to be determined in future studies. | Kevin Sze-Hang Liu Irene Oi-Ling Wong Wai K Leung | 2016 | World Journal of Gastroenterology2016，22，3： | 23 |
| 18 | Contribution of oxidative stress to pulmonary arterial hypertension显示文摘Recent data implicate oxidative stress as a mediator of pulmonary hypertension (PH) and of the associated pathological changes to the pulmonary vasculature and right ventricle (RV). Increases in reactive oxygen species (ROS), altered redox state, and elevated oxidant stress have been demonstrated in the lungs and RV of several animal models of PH, including chronic hypoxia, monocrotaline toxicity, caveolin-1 knock-out mouse, and the transgenic Ren2 rat which overexpresses the mouse renin gene. Generation of ROS in these models is derived mostly from the activities of the nicotinamide adenine dinucleotide phosphate oxidases, xanthine oxidase, and uncoupled endothelial nitric oxide synthase. As disease progresses circulating monocytes and bone marrow-derived monocytic progenitor cells are attracted to and accumulate in the pulmonary vasculature. Once established, these inflammatory cells generate ROS and secrete mitogenic and fibrogenic cytokines that induce cell proliferation and fibrosis in the vascular wall resulting in progressive vascular remodeling. Deficiencies in antioxidant enzymes also contribute to pulmonary hypertensive states. Current therapies were developed to improve endothelial function, reduce pulmonary artery pressure, and slow the progression of vascular remodeling in the pulmonary vasculature by targeting deficiencies in either NO (PDE-type 5 inhibition) or PGI 2 (prostacyclin analogs), or excessive synthesis of ET-1 (ET receptor blockers) with the intent to improve patient clinical status and survival. New therapies may slow disease progression to some extent, but long term management has not been achieved and mortality is still high. Although little is known concerning the effects of current pulmonary arterial hypertension treatments on RV structure and function, interest in this area is increasing. Development of therapeutic strategies that simultaneously target pathology in the pulmonary vasculature and RV may be beneficial in reducing mortality associated with RV failure. | Vincent G DeMarco Adam T Whaley-Connell James R Sowers Javad Habibi Kevin C Dellsperger | 2010 | World Journal of Cardiology2010，2，10： | 21 |
