| 1 | Continuous unidirectional solidification of QAl9-4 Cu-Al alloy显示文摘A continuous unidirectional solidification equipment with the advantages of electric slag remelting, induction heating, continuous casting and unidirectional solidification was built to study the QAl9 4 Cu Al alloy. The results show that the electro slag induction continuous unidirectional solidification process can be used for the steady continuous unidirectional solidification of QAl9 4, and revitalizes the down pulling continuous unidirectional solidification process; that the temperature distribution in the mold wall reflects that of the molten metal in the mold, thus the temperature distribution in the mold wall can be used to control the electric slag induction continuous unidirectional solidification process; and that the mutual matching of the technological parameters is the key to stabilize the solidification process. | Chang Guowei(常国威) Yuan Junping(袁军平) Wang Zidong(王自东) Wu Chunjing(吴春京) Hu Hanqi(胡汉起) Miao Zhimin(苗治民) | 1999 | 中国有色金属学会会刊:英文版1999,9,3: | 8 |
| 2 | Overview of advances in improving uniformity and water use efficiency of sprinkler irrigation显示文摘Water is the scarcest resource and the importance of the judicious use of water in the agricultural sector for sustaining agricultural growth and the retardation of environmental degradation needs no further elaboration.The successes of using sprinkler irrigation to develop new lands,point the way forward to a much greater role for the development of future land reclamation projects.Water use efficiency through a proper improvement of water management techniques and other production factors are essential to boost on-farm productivity.Various factors affecting uniformity and water use efficiency in sprinkler irrigation have been outlined in this research,highlighting possible ways to improve such essential parameters in crop production.The study emphasizes on an irrigation system that works adequately in applying water to stay within the root zone,making the water always available in sufficient quantities to meet the crop water needs.It suggests practical ways of managing irrigation systems within tolerable limits not neglecting the effects of wind which is a major contributing factor to non uniformity in sprinkler irrigation. | Ransford Opoku Darko Yuan Shouqi Liu Junping Yan Haofang Zhu Xingye | 2017 | International Journal of Agricultural and Biological Engineering2017,10,2: | 8 |

| 4 | Robust L_2-L_∞ control for uncertain singular systems with time-varying delay显示文摘We study the problem of L2-L1 control for a class of uncertain singular systems with time-delay and norm-bounded parameter uncertainties in this paper. A new delay-dependent robust stability criterion is obtained in terms of linear matrix inequalities (LMIs). Based on this criterion, a state feedback controller is designed to guarantee that the closed-loop system is regular, impulse free and stable with a prescribed L2-L1 performance satisfied for all admissible parameter uncertainties. A simulation example is included to illustrate the effectiveness of the proposed method. | Lin Li Yingmin Jia Junping Du Shiying Yuan | 2008 | Progress in Natural Science:Materials International2008,18,8: | 5 |
| 5 | Oxidation behavior of Mo-Si-B alloys at medium-to-high temperatures显示文摘Continuous exploration of high-temperature structural materials is being driven by the needs of gasturbine engines capable of withstanding the high-temperature environment.Relatively low melting points of currently applied superalloys restrain the further improvement of service tempe ratures.With higher melting tempe ratures above 2000℃,Mo-Si-B alloys are regarded as a new generation of ultrahightemperature structural materials.However,oxidation is a concern for the industrial application of Mo-Si-B alloys.Therefore,an in-depth understanding of the oxidation mechanisms may contribute to solving this issue,whereas relevant reviews about their recent advances are lacking.In the current work,a comprehensively systematic review about the oxidation behaviors of Mo-Si-B alloys is described for this purpose. | Kunming Pan Yanping Yang Shizhong Wei Honghui Wu Zhili Dong Yuan Wu Shuize Wang Laiqi Zhang Junping Lin Xinping Mao | 2021 | Journal of Materials Science & Technology2021,,1: | 5 |

| 7 | Gender associates with both susceptibility to infection and pathogenesis of SARS-CoV-2 in Syrian hamster显示文摘Epidemiological studies of the COVID-19 patients have suggested the male bias in outcomes of lung illness.To experimentally demonstrate the epidemiological results,we performed animal studies to infect male and female Syrian hamsters with SARS-CoV-2.Remarkably,high viral titer in nasal washings was detectable in male hamsters who presented symptoms of weight loss,weakness,piloerection,hunched back and abdominal respiration,as well as severe pneumonia,pulmonary edema,consolidation,and fibrosis.In contrast with the males,the female hamsters showed much lower shedding viral titers,moderate symptoms,and relatively mild lung pathogenesis.The obvious differences in the susceptibility to SARS-CoV-2 and severity of lung pathogenesis between male and female hamsters provided experimental evidence that SARS-CoV-2 infection and the severity of COVID-19 are associated with gender. | Lunzhi Yuan Huachen Zhu Ming Zhou Jian Ma Rirong Chen Yao Chen Liqiang Chen Kun Wu Minping Cai Junping Hong Lifeng Li Che Liu Huan Yu Yali Zhang Jia Wang Tianying Zhang Shengxiang Ge Jun Zhang Quan Yuan Yixin Chen Qiyi Tang Honglin Chen Tong Cheng Yi Guan Ningshao Xia | 2021 | Signal Transduction and Targeted Therapy2021,6,4: | 3 |
| 8 | Ambulatory blood pressure profile and stroke recurrence显示文摘Objectives To establish a new ambulatory blood pressure(ABP)parameter(24-hour ABP profile)and evaluated its performance on stroke outcome in ischaemic stroke(IS)or transient ischaemic attack(TIA)patients.Methods The prospective cohort consisted of 1996 IS/TIA patients enrolled for ABP monitoring and a 3-month follow-up for stroke recurrence as outcome.Profile groups of systolic blood pressure(SBP)were identified via an advanced functional clustering method,and the associations of the profile groups and conventional ABP parameters with stroke recurrence were examined in a Cox proportional hazards model.Results Three discrete profile groups(n=604,781 and 611 in profiles 1,2 and 3,respectively)in 24-hour ambulatory SBP were identified.Profile 1 resembled most to the normal diurnal blood pressure pattern;profile 2 also dropped at night,but climbed earlier and with higher morning surge;while profile 3 had sustained higher nocturnal SBP without significant nocturnal SBP decline.The incidence of stroke recurrence was 2.9%,3.9%and 5.5%in profiles 1,2 and 3,respectively.After adjustment for covariates,profile 3 was significantly associated with higher risk of stroke recurrence with profile 1 as reference(HR 1.76,95%CI:1.00 to 3.09),while no significant difference was observed between profiles 2 and 1(HR 1.22,95%CI:0.66 to 2.25).None of conventional ABP parameters showed significant associations with the outcome.Conclusions Ambulatory 24-hour SBP profile is associated with short-term stroke recurrence.Profiles of ABP may help improve identification of stroke recurrence by capturing the additive effects of individual ABP parameters. | Jie Xu Fei Jiang Anxin Wang Hui Zhi Yuan Gao Junping Tian Jinglin Mo Zimo Chen An-Ding Xu Benyan Luo Bo Hu Yuqing Zhang Xingquan Zhao Yilong Wang Hao Li Haipeng Shen Yongjun Wang | 2021 | Stroke & Vascular Neurology2021,6,3: | 3 |
| 9 | Delay-dependent H2 control for discrete time-delay systems with D-stability constraints显示文摘This paper studies the problem of H2 control for a class of discrete time-delay systems with D-stability constraints. The corresponding suffcient conditions are given in terms of linear matrix inequalities. In particular, the conditions are delay-dependent, and so they are less conservative. The obtained controller can provide an upper bound for the H2 cost function. A numerical example is given to illustrate the proposed method. | Man Sun Yingmin Jia Junping Du Shiying Yuan | 2008 | Progress in Natural Science:Materials International2008,18,3: | 2 |
| 10 | Long- versus short-interval follow-up after resection of hepatocellular carcinoma: a retrospective cohort study显示文摘Background:Average postoperative follow-up intervals vary in patients undergoing hepatocellular carcinoma(HCC)resection because of limited evidence regarding the optimal interval.We aimed to compare the associations of long-versus short-interval follow-up with survival and recurrence in risk-stratified HCC patients.Methods:We performed a retrospective cohort study between 2007 and 2014.In total,1227 patients treated by curative resection of Barcelona Clinic Liver Cancer stage A or B HCC were stratified as having a low(n=865)or high(n=362)risk of early recurrence(within the first 2 years after resection)based on prognostic factors identified by the least absolute shrinkage and selection operation algorithm.Patients were further classified into long-interval(every 4-6 months)and short-interval(every 2-4 months)follow-up subgroups based on follow-up within 2 years after resection(low risk,long vs.short:n=390 vs.n=475;high-risk,long vs.short:n=149 vs.n=213).Results:The short-interval follow-up did not prolong overall survival in either the low-risk(hazard ratio[HR]=1.152;95%confidence interval[CI]0.720-1.843)or high-risk(HR=1.213;95%CI 0.702-2.094)patients.Early recurrence occurred in 401 patients.For high-risk patients,the short-interval follow-up subgroup exhibited smaller intrahepatic recurrence than did the long-interval group(2.6 vs.3.5 cm,respectively,P=0.045).However,no significant difference in the rate of Barcelona Clinic Liver Cancer stage 0/A recurrence was found between the long-and short-interval follow-up groups in either low-or high-risk patients(63.1%vs.68.2%,respectively,P=0.580;31.3%vs.41.5%,respec-tively,P=0.280).The rate of curative intent treatment for recurrence(34.5%vs.39.7%,respectively,P=0.430;14.6%vs.20.3%,respectively,P=0.388)was also similar between the follow-up groups for low-and high-risk patients.Conclusions:Shortening the postoperative follow-up interval from every 4-6 months to every 2-4 months within the first 2 years after resection did not increase the rate of curative intent treatment or prolong the overall survival of patients with Barcelona Clinic Liver Cancer stage A or B HCC. | Wei He Yun Zheng Ruhai Zou Jingxian Shen Junping Yang Jiliang Qiu Qiang Tao Wenwu Liu Zhiwen Yang Yuanping Zhang Binkui Li Yunfei Yuan | 2018 | Cancer Communications2018,38,1: | 2 |
| 11 | Optimization of movable irrigation system and performance assessment of distribution uniformity under varying conditions显示文摘The evaluation of the performance of distribution uniformity by linearly moved irrigation system(LMIS)should consider the impacts of non uniformity of the water on crop yield.With increasing pressures to improve water use efficiency,plant productivity and farm profitability,questions continue to be raised concerning the future direction of irrigated agriculture.This study therefore aimed at evaluating water distribution under LMIS newly designed by the National Research Centre of Fluid Machinery Engineering and Technology,Jiangsu University,China.This article reports the real distribution of irrigation water under the LMIS with respect to sprinkler height above the ground surface as well as the consequence of different operating pressures.Water distribution coefficients used in the performance assessment were Christiansen’s coefficient of uniformity(CU),distribution uniformity(DU),scheduling coefficients(Sc)and the coefficient of variation(CV).The results showed that the mean CU ranged from 82.30%to 93.17%,and mean DU ranged from 70.39%to 88.44%.Also Sc values ranged from 1.13 to 1.42 with CV values ranging from 10.3%to 22.5%.The optimum method and results in this study can provide a reference to the operations for saving water and cost in the application of LMIS. | Yuan Shouqi Ransford Opoku Darko Zhu Xingye Liu Junping Tian Kun | 2017 | International Journal of Agricultural and Biological Engineering2017,10,1: | 2 |
| 12 | Agrobacterium tumefaciens-mediated transformation of modern rose(Rosa hybrida)using leaf-derived embryogenic callus显示文摘Rose(Rosa hybrida)is widely used for cut flowers and as garden plants.Stable and efficient transformation system is required for functional genomics of rose.Here,we established an efficient transformation method for rose using Agrobacterium tumefaciens-mediated transformation of embryogenic callus.Expanding rose leaves were used as explants to induce somatic embryos,which were subjected to transformation with A.tumefaciens strain GV3101 using Green Fluorescence Protein(GFP)as a marker gene.It took about 8 months to generate transgenic shoots from embryogenic callus.PCR,RT-PCR,Southern and Western blotting,as well as stereoscopic fluorescence microscopy analysis demonstrated that GFP transgenes integrated stably into the rose genome.According to our data,a transformation efficiency of up to 6%can be achieved by following this optimized protocol. | Guoqin Liu Yuan Yuan Hui Jiang Ying Bao Guogui Ning Liangjun Zhao Xiaofeng Zhou Hougao Zhou Junping Gao Nan Ma | 2021 | Horticultural Plant Journal2021,7,4: | 1 |
| 13 | Comparison of droplet distributions from fluidic and impact sprinklers显示文摘To adapt to the trend toward low-energy precision irrigation, the droplet distributions for two new prototype sprinklers, outside signal sprinkler(OS) and fluidic sprinkler(FS), were compared with impact sprinkler(IS). A laser precipitation monitor was used to measure the droplet distributions. Droplet size and velocity distributions were tested under four operating pressures for nozzles 1.5 m above the ground. For the operating pressures tested, the mean OS, FS and IS droplet diameters ranged from 0 to 3.4, 0 to 3.5, 0 to 4.0 mm, respectively.The mean OS and FS droplet velocities ranged from 0 to6.3 m$s–1, whereas IS ranged from 0 to 6.3 m$s–1. Being gas-liquid fluidic sprinklers, droplet distributions of the OS and FS were similar, although not identical. IS mostly produced a 0.5 mm larger droplet diameter and a 0.5 m$s–1greater velocity than OS and FS. A new empirical equation is proposed for determination of droplet size for OS and FS, which is sufficiently accurate and simple to use. Basic statistics for droplet size and velocity were performed on data obtained by the photographic methods. The mean droplet diameter(arithmetic, volumetric and median)decreased and the mean velocity increased in operating pressure for the three types of sprinkler. | Xingye ZHU Shouqi YUAN Junping LIU Xingfa LIU | 2015 | Frontiers of Agricultural Science and Engineering2015,2,1: | 1 |
| 14 | An international Delphi consensus statement on metabolic dysfunction-associated fatty liver disease and risk of chronic kidney disease显示文摘Background:With the rising global prevalence of fatty liver disease related to metabolic dysfunction,the association of this common liver condition with chronic kidney disease(CKD)has become increasingly evident.In 2020,the more inclusive term metabolic dysfunction-associated fatty liver disease(MAFLD)was proposed to replace the term non-alcoholic fatty liver disease(NAFLD).The observed association between MAFLD and CKD and our understanding that CKD can be a consequence of underlying metabolic dysfunction support the notion that individuals with MAFLD are at higher risk of having and developing CKD compared with those without MAFLD.However,to date,there is no appropriate guidance on CKD in individuals with MAFLD.Furthermore,there has been little attention paid to the link between MAFLD and CKD in the Nephrology community.Methods and Results:Using a Delphi-based approach,a multidisciplinary panel of 50 international experts from 26 countries reached a consensus on some of the open research questions regarding the link between MAFLD and CKD.Conclusions:This Delphi-based consensus statement provided guidance on the epidemiology,mechanisms,management and treatment of MAFLD and CKD,as well as the relationship between the severity of MAFLD and risk of CKD,which establish a framework for the early prevention and management of these two common and interconnected diseases. | Dan-Qin Sun Giovanni Targher Christopher D.Byrne David C.Wheeler Vincent Wai-Sun Wong Jian-Gao Fan Herbert Tilg Wei-Jie Yuan Christoph Wanner Xin Gao Michelle T.Long Mehmet Kanbay Mindie H.Nguyen Sankar D.Navaneethan Yusuf Yilmaz Yuli Huang Rino A.Gani Pierluigi Marzuillo Jérôme Boursier Huijie Zhang Chan-Young Jung Jin Chai Luca Valenti George Papatheodoridis Giovanni Musso Yu-Jun Wong Mohamed El-Kassas Nahum Méndez-Sánchez Silvia Sookoian Michael Pavlides Ajay Duseja Adriaan G.Holleboom Junping Shi Wah-Kheong Chan Yasser Fouad Junwei Yang Sombat Treeprasertsuk Helena Cortez-Pinto Masahide Hamaguchi Manuel Romero-Gomez Mamun Al Mahtab Ponsiano Ocama Atsushi Nakajima Chunsun Dai Mohammed Eslam Lai Wei Jacob George Ming-Hua Zheng | 2023 | Hepatobiliary Surgery and Nutrition2023,12,3: | 1 |
| 15 | Calibration and validation of AquaCrop for deficit and full irrigation of tomato显示文摘The objective of this study was to calibrate and test AquaCrop for tomato(Lycopersicon esculentum)grown under deficit and full irrigation.Two field experiments were carried out in the tropical humid coastal savanna zone in Mfantseman district of the Central Region of Ghana.Data from the first experiment were used to calibrate the model while data obtained from the second experiment were used to validate the model.The calibrated AquaCrop model concentrated on its performance to predict crop yield and seasonal crop water requirement(ETc).Four treatments were investigated:T1(no irrigation after plant establishment),T2(50%ETc restoration),T3(100%ETc restoration up to beginning of flowering,then 50%ETc restoration)and T4(100%ETc restoration).The results revealed that AquaCrop was able to simulate the yield of tomato for T2-T4 with the exception of Treatment T1 which was simulated with the highest deviation of 45.1%.On the other hand,the model was able to simulate the seasonal water requirements to an appreciable degree in both experiments.It must be pointed out that the calibration of AquaCrop suffered from a lack of data on the progress of crop canopy cover which is a very important parameter used in developing the model. | Ransford Opoku Darko Yuan Shouqi Yan Haofang Liu Junping Agnes Abbey | 2016 | International Journal of Agricultural and Biological Engineering2016,9,3: | 1 |

| 20 | Study of Ce-modified antibacterial 316L stainless steel显示文摘316L stainless steel is widely used for fashion jewelry, but it can carry a large number of bacteria and bring the risk of infection since the steel has no antimicrobial performance. In this paper, the effects of Ce on the antibacterial property, corrosion resistance and processability of 316L were studied by microscopic observation, thin- film adhering quantitative bacteriostasis, and electrochemical and mechanical tests. The results show that a trace of Ce can distribute uniformly in the matrix of 316L and slightly improve its corrosion resistance in artificial sweat. With an increase in Ce content, the Ce is prone to form clustering, which degrades the corrosion resistance and the processability. The Ce-containing 316L exhibits Hormesis effect against S. aureus. A small Ce addition stimulates the growth of S. aureus. As the Ce content increases, the modified 316L exhibits an improved antibacterial efficacy. The more Ce is added, the better antibacterial capability is achieved. Overall, if the 316L is modified with Ce alone, it is difficult to obtain the optimal combination of corrosion resistance, antibacterial performance and processability. In spite of that, 0.15 wt.%-0.20 wt.% Ce around is inferred to be the best trade-off. | Yuan Junping Li Wei Shen Keya | 2012 | China Foundry2012,9,4: | 1 |
