| 1 | Seismic damage of highway bridges during the 2008 Wenchuan earthquake显示文摘Many highway bridges were severely damaged or completely collapsed during the 2008 Wenchuan earthquake.A fi eld investigation was carried out in the strongly affected areas and over 320 bridges were examined.Damage to some representative highway bridges is briefly described and a preliminary analysis of the probable causes of the damage is presented in this paper.The most common damage included shear-flexural failure of the pier columns,expansion joint failure,shear key failure,and girder sliding in the transversal or longitudinal directions due to weak connections between girder and bearings.Lessons learned from this earthquake are described and recommendations related to the design of curved and skewed bridges,design of bearings and devices to prevent girder collapse,and ductility of bridge piers are presented.Suggestions for future seismic design and retrofi tting techniques for bridges in moderate to severe earthquake areas are also proposed. | Han Qiang Du Xiuli Liu Jingbo Li Zhongxian Li Liyun Zhao Jianfeng | 2009 | Earthquake Engineering and Engineering Vibration2009,8,2: | 60 |
| 2 | Potential and challenges of tannins as an alternative to in-feed antibiotics for farm animal production显示文摘Naturally occurring plant compounds including tannins, saponins and essential oils are extensively assessed as natural alternatives to in-feed antibiotics.Tannins are a group of polyphenolic compounds that are widely present in plant region and possess various biological activities including antimicrobial,anti-parasitic, anti-viral, antioxidant, anti-inflammatory, immunomodulation, etc.Therefore, tannins are the major research subject in developing natural alternative to in-feed antibiotics.Strong protein affinity is the well-recognized property of plant tannins, which has successfully been applied to ruminant nutrition to decrease protein degradation in the rumen, and thereby improve protein utilization and animal production efficiency.Incorporations of tannin-containing forage in ruminant diets to control animal pasture bloat, intestinal parasite and pathogenic bacteria load are another 3 important applications of tannins in ruminant animals.Tannins have traditionally been regarded as 'anti-nutritional factor' for monogastric animals and poultry, but recent researches have revealed some of them, when applied in appropriate manner, improved intestinal microbial ecosystem, enhanced gut health and hence increased productive performance.The applicability of plant tannins as an alternative to in-feed antibiotics depends on many factors that contribute to the great variability in their observed efficacies. | Qianqian Huang Xiuli Liu Guoqi Zhao Tianming Hu Yuxi Wang | 2018 | Animal Nutrition2018,,2: | 54 |

| 5 | Effects of Water-table Depth and Soil Moisture on Plant Biomass, Diversity, and Distribution at a Seasonally Flooded Wetland of Poyang Lake, China显示文摘Hydrological regime has been widely recognized as one of the major forces determining vegetation distribution in seasonally flooded wetland. Poyang Lake, the largest freshwater lake in China, has been encountering dramatic changes in hydrological conditions in last decade, which greatly influenced the wetland vegetations. To explore the relationships between hydrology and vegetation distribution, water-table depth, soil moisture, species composition, diversity and biomass were measured at a seasonally flooded wetland section at Wucheng National Nature Reserve. Three plant communities, Artemisia capillaris, Phragmites australis and Carex cinerascens communities, were examined which are zonally distributed from upland to lakeshore with decreasing elevation. Canonical correspondence analysis(CCA), spearmen correlation and logistic regression were adopted to analyze the relationships between vegetation characteristics and hydrological variables of water-table depth and soil moisture. Results show that significant hydrological gradient exist along the wetland transect. Water-table demonstrates a seasonal variation and is consistently deepest in A. capillaris community(ranging from –0.5 m above ground to +10.3 m below ground), intermediate in P. australis community(–2.6 m to +7.8 m) and shallowest in C. cinerascens community(–4.5 m to +6.1 m). Soil moisture is lowest and most variable in A. capillaris community, highest and least variable in P. australis community, and intermediate and moderate variable in C. cinerascens community. The CCA ordination indicated that variables of water-table depth and soil moisture are strongly related to community distribution, which explained 81.7% of the vegetation variations. Species diversity indices are significantly positively correlated with soil moisture and negatively correlated with moisture variability, while above- and belowground biomass are positively correlated with moisture. Above- and belowground biomass present Gaussian models along the gradient of average water-table depth in growing season, while species diversity indices show bimodal patterns. The optimal average water-table depths for above- and belowground biomass are 0.8 m and 0.5 m, respectively, and are 2.2 m and 2.4 m for species richness and Shannon-Wiener indices, respectively. Outcomes of this work improved the understandings of the relationship between hydrology and vegetation. | XU Xiuli ZHANG Qi TAN Zhiqiang LI Yunliang WANG Xiaolong | 2015 | Chinese Geographical Science2015,25,6: | 24 |

| 8 | Numerical simulation of powder transport behavior in laser cladding with coaxial powder feeding显示文摘Laser cladding with coaxial powder feeding is one of the new processes applied to produce well bonding coating on the component to improve performance of its surface. In the process, the clad material is transported by the carrying gas through the coaxial nozzle, generating gas-powder flow. The powder feeding process in the coaxial laser cladding has important influence on the clad qualities. A 3D numerical model was developed to study the powder stream structure of a coaxial feeding nozzle. The predicted powder stream structure was well agreed with the experimental one. The validated model was used to explore the collision behavior of particles in the coaxial nozzle, as well as powder concentration distribution. It was found that the particle diameter and restitution coefficient greatly affect the velocity vector at outlet of nozzle due to the collisions, as well as the powder stream convergence characteristics below the nozzle. The results indicated a practical approach to optimize the powder stream for the coaxial laser cladding. | LIU Hao HE XiuLi YU Gang WANG Zhong Bin LI ShaoXia ZHENG CaiYun NING WeiJian | 2015 | Science China(Physics,Mechanics & Astronomy)2015,58,10: | 17 |

| 12 | Western medication plus Traditional Chinese Medicine preparations in patients with chronic heart failure:a prospective,single-blind,randomized,controlled,and multicenter clinical trial显示文摘OBJECTIVE: To assess the efficacy and safety in patients with chronic heart failure(CHF) of Western medication plus Traditional Chinese Medicine(TCM) preparations.METHODS: This prospective, single-blind, randomized, controlled, and multicenter clinical trial began on September 17, 2008, and was completed on June 25, 2011. A total of 340 inpatients, aged 40-79 years, with exacerbating CHF from 10 hospitals were enrolled and randomly allocated within 24 h of admission. The trial included three intervention periods. During hospitalization, the control group received western medication for CHF and the treatment group received Danhong injection with Shenfu injection or Shenmai injection. After discharge,all patients were treated with Qiliqiangxin capsules and Buyiqiangxin tablets or a placebo for 6 months. After the 6-month intervention, both groups received only continuous western medication. The primary endpoint was all-cause mortality.The efficacy assessments were as follows: B-type natriuretic peptide(BNP), Lee's HF score, the 6-minute walking test(6 MWT), left ventricular ejection fraction(LVEF), and the Minnesota Living with Heart Failure Questionnaire(MLHFQ). The safety assessments were as follows: blood and urine routine examination, hepatic and renal function, electrolytes in blood and adverse events.RESULTS: Compared with the control group, the treatment group showed a 30.99% reduction in all-cause mortality and an improved survival rate.The treatment group showed greater improvement in 6 MWT(P = 0.02) than the control group on discharge, after 12-month follow-up, there was a time-group interaction for MLHFQ(P = 0.03). Incidence rate of adverse events and other relevant safety indexes were not statistically significant between the two groups.CONCLUSION: Western medication plus TCM treatment can increase 6-minute walking distance(improve exercise tolerance) and quality of life with heart failure patients. | Wang Xianliang Hou Yazhu Mao Jingyuan Zhao Yingqiang Niu Tianfu Yuan Ruyu Wang Yonggang Cui Jin-rong Shi Le Jia Xiuli Fan Ruihong Lin Qian Zhang Yan Li Zhijun Shang Hongcai Wang Baohe Wang Hongwu Wang Henghe Cui Xiaolei Soh Shanbin Ruan Jishou Zhang Boli | 2017 | Journal of Traditional Chinese Medicine2017,37,6: | 15 |
| 13 | Preparation of Zn-doped TiO_2 nanotubes electrode and its application in pentachlorophenol photoelectrocatalytic degradation显示文摘Zn-doped titanium oxide (TiO2) nanotubes electrode was prepared on a titanium plate by direct anodic oxidation and immersing method in sequence. Field emission scanning electron microscopy (FESEM) showed that the Zn-doped TiO2 nanotubes were well aligned and organized into high density uniform arrays with diameter ranging from 50 to 90 nm. The length and the thickness were about 200 and 15 nm respectively. TiO2 anatase phase was identified by X-ray diffraction (XRD). X-ray photoelectronspec-troscopy (XPS) indicated that Zn ions were mainly located on the surface of TiO2 nanotubes in form of ZnO clusters. Compared with TiO2 nanotubes electrode,about 20 nm red shift in the spectrum of UV-vis absorption was observed. The degradation of pentachlorophenol (PCP) in aqueous solution under the same condition (initial concentration of PCP: 20 mg/L; concentration of Na2SO4: 0.01 mol/L and pH: 7.03) was carried out using Zn-doped TiO2 nanotubes electrode and TiO2 nanotubes electrode. The degradation rates of PCP using Zn-doped TiO2 nanotubes electrode were found to be twice and 5.8 times as high as that using TiO2 nanotubes electrode by UV radiation (400 μw/cm2) and visible light radiation (4500 μw/cm2),respectively. 73.5% of PCP was removed using Zn-doped TiO2 nanotubes electrode against 48.5% removed using TiO2 nanotubes electrode in 120 min under UV radiation. While under visible light radiation,the degradation efficiency of PCP was 18.4% using Zn-doped TiO2 nano-tubes electrode against 3.2% using TiO2 nanotubes electrode in 120 min. The optimum concentration of Zn doping was found to be 0.909%. The PCP degradation efficiencies of the 10 repeated experiments by Zn-doped TiO2 nanotubes electrode were rather stable with the deviation within 3.0%. | ZHAO HuiMin CHEN Yue QUAN Xie RUAN XiuLi | 2007 | Chinese Science Bulletin2007,52,11: | 14 |

| 15 | Influence of Long-Term Fertilization on Selenium Accumulation in Soil and Uptake by Crops显示文摘Continuous applications of organic and inorganic fertilizers can affect soil and food quality with respect to selenium(Se) concentrations.A long-term(over 20 years) experimental field study,started in 1989,was conducted to investigate the changes in soil Se fractions and its uptake by crops,as affected by different fertilizer practices,in the North China Plain with an annual crop rotation of winter wheat and summer maize.The long-term experiment was arranged in a complete randomized block design consisting of 4replications with 7 fertilizer treatments:1) organic compost(OC),2) half organic compost plus half N-P-K chemical fertilizers(OC+ NPK),3) N-P-K fertilizers(NPK),4) N-P fertilizers(NP),5) P-K fertilizers(PK),6) N-K fertilizers(NK),and 7) an un-amended control.Soil samples from the surface(20 cm) were collected in 1989,1994,1999,2004 and 2009 to characterize Se and other soil properties.In 2009,the average soil Se concentrations in the treatments(149 ± 8 μg kg^(-1)) were higher than those in the soil samples collected in 1989 at the beginning of the experiment(112 ± 4 μg kg^(-1)),and decreased in the order of OC > OC + NPK > NPK≈NP > PK ≈NK > control.Sequential extraction showed the oxidizable fraction(50.06%± 3.94%) was the dominant form of Se in the soil,followed by the residual fraction(24.12%± 2.89%),exchangeable fraction(15.09%± 4.34%) and Fe-Mn oxides fraction(10.73%± 4.04%).With an increase of soil K,the exchangeable Se concentrations in the soil increased.The Se concentrations in the soil tillage layer(0-20 cm) were mainly related to soil organic carbon(SOC),although different contributions came from atmospheric deposition,irrigation and fertilizers.With the accumulation of SOC,the uptakes of soil Se by two crops were inhibited.For the OC and OC + NPK treatments,Se concentrations in wheat grains were lower than the critical standard of Se in stable food(100 μg kg^(-1)).Additionally,Se concentrations in grains were also decreased by the deficiencies of major soil nutrients,especially P. | WANG Qingyun ZHANG Jiabao ZHAO Bingzi XIN Xiuli DENG Xihai Hailin ZHANG | 2016 | Pedosphere2016,26,1: | 12 |
| 16 | Major and trace element geochemistry of the mid-Bay of Bengal surface sediments: implications for provenance显示文摘The major and trace elements in 110 surface sediment samples collected from the middle of the Bay of Bengal(mid-Bay of Bengal) are analyzed to investigate provenance. Si levels are highest, followed by Al, and the distributions of these two elements are identical. The average CIA*(chemical index of alteration) value is 72.07,indicating that the degree of weathering of the sediments in the study area is intermediate between those of sediments of the Himalayan and Indian rivers. Factor analyses and discrimination function analyses imply that the two main provenances are the Himalayan and the Indian continent. The inverse model calculation of the Tinormalized element ratios of the Bay of Bengal sediments indicate an estimated average contribution of 83.5%and 16.5% from the Himalayan and peninsular Indian rivers to the study area, respectively. The Himalayan source contributes more sediment to the eastern part of the study area, whereas the western part receives more sediment from the Indian Peninsula than did the eastern part. The primary mechanisms for deposition of sediments in the study area are the transport of Himalayan matter by turbidity currents and river-diluted water and the transport of Indian matter to the study area by a surface circulation in the Bay of Bengal, particularly the East India Coastal Current. | LI Jingrui LIU Shengfa FENG Xiuli SUN Xingquan SHI Xuefa | 2017 | Acta Oceanologica Sinica2017,36,3: | 12 |
| 17 | A SURVEY OF STACKELBERG DIFFERENTIAL GAME MODELS IN SUPPLY AND MARKETING CHANNELS显示文摘Stackelberg differential game models have been used to study sequential decision making in noncooperative games in diverse fields.In this paper,we survey recent applications of Stackelberg differential game models to the supply chain management and marketing channels literatures.A common feature of these applications is the specification of the game structure:a decentralized channel composed of a manufacturer and independent retailers,and a sequential decision procedure with demand and supply dynamics and coordination issues.In supply chain management,Stackelberg differential games have been used to investigate inventory issues,wholesale and retail pricing strategies,and outsourcing in dynamic environments.The underlying demand typically has growth dynamics or seasonal variation.In marketing,Stackelberg differential games have been used to model cooperative advertising programs,store brand and national brand advertising strategies,shelf space allocation,and pricing and advertising decisions.The demand dynamics are usually extensions of the classical advertising capital models or sales-advertising response models.We begin by explaining the Stackelberg differential game solution methodology and then provide a description of the models and results reported in the literature. | Xiuli HE Ashutosh PRASAD Suresh P.

| 18 | Spatial gradient distributions of thermal shock-induced damage to granite显示文摘In this study,we attempted to investigate the spatial gradient distributions of thermal shock-induced damage to granite with respect to associated deterioration mechanisms.First,thermal shock experiments were conducted on granite specimens by slowly preheating the specimens to high temperatures,followed by rapid cooling in tap water.Then,the spatial gradient distributions of thermal shock-induced damage were investigated by computed tomography(CT)and image analysis techniques.Finally,the influence of the preheating temperature on the spatial gradients of the damage was discussed.The results show that the thermal shock induced by rapid cooling can cause more damage to granite than that induced by slow cooling.The thermal shock induced by rapid cooling can cause spatial gradient distributions of the damage to granite.The damage near the specimen surface was at a maximum,while the damage inside the specimen was at a minimum.In addition,the preheating temperature can significantly influence the spatial gradient distributions of the thermal shock-induced damage.The spatial gradient distribution of damage increased as the preheating temperature increased and then decreased significantly over 600C.When the preheating temperature was sufficiently high(e.g.800C),the gradient can be ignored. | Lifeng Fan Jingwei Gao Xiuli Du Zhijun Wu | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020,12,5: | 11 |
| 19 | Interface issues of lithium metal anode for high-energy batteries: Challenges, strategies, and perspectives显示文摘Lithium(Li)metal is considered as one of the most promising anode materials for next-generation high-energy-density storage systems.However,the practical application of Li metal anode is hindered by interfacial instability and air instability due to the highly reactivity of Li metal.Unstable interface in Li metal batteries(LMBs)directly dictates Li dendrite growth,“dead Li”and low Coulombic efficiency,resulting in inferior electrochemical performance of LMBs and even safety issues.In addition,its sensitivity to ambient air leads to the severe corrosion of Li metal anode,high requirements of production and storage,and increased manufacturing cost.Plenty of efforts in recent years have overcome many bottlenecks in these fields and hastened the practical applications of high-energy-density LMBs.In this review,we focus on emerging methods of these two aspects to fulfill a stable and low cost electrode.In this perspective,design artificial solid electrolyte interphase(SEI)layers,construct three-dimensional conductive current collectors,optimize electrolytes,employ solid-state electrolytes,and modify separators are summarized to be propitious to ameliorate interfacial stability.Meanwhile,ex situ/in situ formed protective layers are highlighted in favor of heightening air stability.Finally,several possible directions for the future research on advanced Li metal anode are addressed. | Yiyao Han Bo Liu Zhen Xiao Wenkui Zhang Xiuli Wang Guoxiang Pan Yang Xia Xinhui Xia Jiangping Tu | 2021 | InfoMat2021,3,2: | 11 |
