| 1 | Simulation of the Whole Process of Ship-Bridge Collision显示文摘The simulation of the whole ship-bridge collision process can be effectively carried out by nonlinear dynamic finiteelement method. Based on the simple description of the theory, a scenario of a 40000 DWT oil tanker colliding with abridge across the Yangtze River is designed for simulation. The technology of structure modeling and the determination ofrelated parameters are introduced. The deformation of the bulb bow, the history of collision force change, the exchange ofcollision energy and the stress distribution of the bridge pier are described in detail, which are of great value to bridge de-sign and bridge pier damage estimation, Some mechanical characters in the process of ship-bridge collision are described.More accurate results can be produced by finite element method than that by empirical formulas and simplified analyticalmethods. | LIU Jiancheng(刘建成) GU Yongning(顾永宁) | 2002 | China Ocean Engineering2002,17,3: | 15 |

| 3 | Phase demodulation method based on a dual-identical-chirped-pulse and weak fiber Bragg gratings for quasi-distributed acoustic sensing显示文摘A phase demodulation method for quasi-distributed acoustic sensing(DAS)systems based on a dual-identicalchirped-pulse and weak fiber Bragg gratings(WFBGs)is proposed.Compared to the use of Rayleigh backscattering light in optical fibers,the implementation of WFBGs can contribute to obtaining an optical signal with a higher signal-to-noise ratio(SNR).The dual-identical-chirped-pulse is generated by a time-delay fiber,and the sinusoidal carrier is generated by the interference between the two chirped pulses reflected by adjacent WFBGs.The phase of the sinusoidal carrier represents the dynamic strain change posed on the sensing fiber.Discrete Fourier transform is used to directly retrieve the phase information.The performance of the phase demodulation from interference signals under different sinusoidal carrier frequencies and SNRs is numerically investigated.The piezoelectric transducer is employed to emulate the sound in the experiment to verify the effectiveness of our method.It is shown that the dynamic strain can be well reconstructed at the end of a 101.64 km fiber when the signal SNR is down to 3.234 d B.Our proposed method enables the application of the long-distance sensing in quasi-DAS systems. | Guanhua Liang Junfeng Jiang Kun Liu Shuang Wang Tianhua Xu Wenjie Chen Zhe Ma Zhenyang Ding Xuezhi Zhang Yongning Zhang Tiegen Liu | 2020 | Photonics Research2020,8,7: | 6 |

| 5 | Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery. | Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018,30,5: | 5 |
| 6 | Tenofovir Alafenamide Fumarate,Tenofovir Disoproxil Fumarate and Entecavir:Which is the Most Effective Drug for Chronic Hepatitis B?A Systematic Review and Meta-analysis显示文摘Background and Aims:The therapeutic effect of tenofovir alafenamide fumarate(TAF),tenofovir disoproxil fumarate(TDF)and entecavir(ETV)on chronic hepatitis B(CHB)patients remains inconsistent.The aim of this study was to explore the differences in virological responses to TAF,TDF and ETV in patients with CHB.Methods:Literature searches were conducted of the PubMed,EMBASE,and the Cochrane Library databases to identify randomized controlled trials and observational studies published up to July 21,2020.Statistical comparisons of virological response between TDF,ETV,and TAF were carried out with pooled odds ratio(OR)values.Results:The virological response in TDF-treated CHB patients was notably superior to that of the ETV-treated CHB patients after 12-weeks[OR=1.12,95%confidence interval(CI):0.89–1.41],24-weeks(OR=1.33,95%CI:1.11–1.61),48-weeks(OR=1.62,95%CI:1.16–2.25),72-weeks(OR=1.43,95%CI:0.78–2.62),and 96-weeks(OR=1.56,95%CI:0.87–2.81)treatment.No significant difference was observed for the virological responses in CHB patients after 48-weeks treatment with TAF or TDF.The virological response in TDF+ETV-treated CHB patients was superior to that of TDF-treated CHB patients after 24-weeks,48-weeks(OR=1.54,95%CI:1.17–2.02),96-weeks,and 144-weeks.Conclusions:The virological response in TDF-treated CHB patients was superior to that in ETV-treated CHB patients,but there was no significant difference between TAF and TDF.In addition,the therapeutic effect of TDF+ETV was superior to TDF alone. | Xuefeng Ma Shousheng Liu Mengke Wang Yifen Wang Shuixian Du Yongning Xin Shiying Xuan | 2021 | Journal of Clinical and Translational Hepatology2021,9,3: | 3 |

| 8 | Coordinated Damping Optimization Control of Sub-synchronous Oscillation for DFIG and SVG显示文摘Currently, the power electronics-based devices, includinglarge-scale non-synchronized generators and reactivepower compensators, are widely used in power grids. This helpsintroduce the coupling interactions between the devices andthe power grid, resulting in a new sub-synchronous oscillationphenomenon. It is a critical element for the stability operation ofthe power grid and its devices. In this paper, the sub-synchronousoscillation phenomenon of the power grid connected with largescalewind power generation is analyzed in detail. Then, inorder to damp the sub-synchronous oscillation, a coordinateddamping optimization control strategy for wind power generatorsand their reactive power compensators is proposed. The proposedcoordinated control strategy tracks the sub-synchronousoscillation current signal to correct the corresponding controlsignal, which increases the damping of power electronics. Theresponse characteristics of the proposed control strategy areanalyzed, and a self-optimization parameter tuning method basedon sensitivity analysis is proposed. The simulation results validatethe effectiveness and the availability of the proposed controlstrategy. | Xinshou Tian Yongning Chi Yan Li Haiyan Tang Chao Liu Yuanyuan Su | 2021 | CSEE Journal of Power and Energy Systems2021,7,1: | 3 |
| 9 | Development of wind-energy modeling technology and standards显示文摘To ensure the stable operation of power systems with large proportions of wind power,China has published a series of national,industry,and enterprise standards for wind power.The increase in the number of standards and the expansion of their application scope have given rise to a situation where multiple standards overlap and conflict with regard to the establishment of models and their applicability,resulting in unclear standard application scenarios.Therefore,it is imperative to analyze the development of wind-turbine and wind-farm modeling,along with the relevant standards.This paper presents the methods for wind-turbine modeling,the equivalent model of wind farms based on the general model of wind turbines,and the technical provisions and application scenarios involved in the relevant domestic and international standards.The adaptability of the relevant standards is examined.The results of this study are helpful for advancing wind power generation in China and ensuring the safe and stable operation of large-scale wind power systems. | Cong Wang Yan Li Yiwen Fan Yongning Chi Hongchang Qi Hongzhi Liu | 2022 | Global Energy Interconnection2022,5,2: | 3 |

| 14 | Structure and electrochemical properties of low-cobalt La_(1-x)Li_xNi_(3.2)Co_(0.3)Al_(0.3) (0≤x≤0.2) hydrogen storage electrode alloys显示文摘The structure and electrochemical properties of a new low cobalt hydrogen storage electrode alloys La1-xLixNi3.2Co0.3Al0.3 (0≤x≤0.2) were investigated with a different additions of Li in replacement of La. With the increase of Li contents the maximum discharge capacity increases from 240 mAh·g-1(x=0) to 328.4 mAh·g-1(x=0.1) and the cycle stability is improved correspondingly. The capacity decay can remain 28.6% (x=0.2) after 230 charge/discharge cycles. The high rate discharge(HRD) ability of the alloys(x≤0.1) is improved and the best HRD is 34.1%(x=0.1) under the discharge current density 1200 mA·g-1. It is found that the prepared alloys are basically composed of LaNi5 as matrix phase and LaNi3 as second phase(x≤0.1). But the abundance of LaNi3 phase dramatically decreases with increasing x. When x=0.2, a new phase Al(NiCo)3 is formed. | WEI Xuedong LIU Yongning ZHANG Peng | 2006 | Rare Metals2006,25,z1: | 2 |

| 17 | Spheroidization process in large-deformed high-carbon steel显示文摘In this study,the spheroidization process of large-deformed steel under various conditions was researched. Steel with a high carbon content(1.0% C)was first treated thermomechanically using multipass rolling.Then it underwent spheroidization treatments at different heating temperatures,using various heating times and cooling rates.Spheroidization processes with a lower heating temperature,shorter heating time,or faster cooling rate than those of the traditional process all showed good results,indicating that the spheroidization process was promoted significantly by the large deformation process.Grain refinement and fragmentation of cementite,along with the large deformation process,promoted this spheroidization process. | LIAN Fuliang LIU Yongning | 2014 | Baosteel Technical Research2014,8,1: | 2 |
| 18 | Research progress on distribution,sources,identification,toxicity,and biodegradation of microplastics in the ocean,freshwater,and soil environment显示文摘Microplastics(MPs)are distributed in the oceans,freshwater,and soil environment and have become major pollutants.MPs are generally referred to as plastic particles less than 5 mm in diameter.They consist of primary microplastics synthesized in microscopic size manufactured production and secondary microplastics generated by physical and environmental degradation.Plastic particles are long-lived pollutants that are highly resistant to environmental degradation.In this review,the distribution and possible sources of MPs in aquatic and terrestrial environments are described.Moreover,the adverse effects of MPs on natural creatures due to ingestion have been discussed.We also have summarized identification methods based on MPs particle size and chemical bond.To control the pollution of MPs,the biodegradation of MPs under the action of different microbes has also been reviewed in this work.This review will contribute to a better understanding of MPs pollution in the environment,as well as their identification,toxicity,and biodegradation in the ocean,freshwater,and soil,and the assessment and control of microplastics exposure. | Qinghui Sun Juan Li Chen Wang Anqi Chen Yanli You Shupeng Yang Huihui Liu Guibin Jiang Yongning Wu Yanshen Li | 2022 | Frontiers of Environmental Science & Engineering2022,16,1: | 2 |
| 19 | Study on the Carry Capacity of Edible Jellyfish Fishery in Liaodong Bay显示文摘Jellyfish fishing is a special type of fishery that mainly exists in some countries of East and Southeast Asia. China has the largest jellyfish fishery yield in the world with an annual harvest of around 300 thousand tons. Liaodong Bay is the most important jellyfish fishery ground in China. However, due to the high benefits of jellyfish fishery, which leads to illegal and out-of-season jellyfish fishing occurring each year in Liaodong Bay. Illegal jellyfish fishery in Liaodong Bay is a typical example of the tragedy of the commons. The key problem is that fishermen seek to an illegally initiate jellyfish fishing as early as possible. In this paper, basing on the data of edible jellyfish's biology and ecology, we mainly analyzed the history of jellyfish fishery in China, especially in Liaodong bay, and then we calculated the carry capacity of edible jellyfish in Liaodong Bay which is about 300 thousand tons one year. This number is equal to the recent annual yield of edible jellyfish in China. Furthermore, basing on the carry capacity and reasonable quotas price analysis, we set up a Jellyfish fishing quotas and deficit quotas buyback system which could be a suitable and effective solution for jellyfish fishery management and development in Liaodong Bay at the underlying roots. Although China is the first country with edible jellyfish aquaculture, the annual yield of jellyfish aquaculture is only one fifth of jellyfish fishing. So, there is a very bright developing prospect about edible jellyfish aquaculture in China. | YOU Kui BIAN Yongning MA Caihua CHI Xupeng LIU Zhiqiang ZHANG Yuyu | 2016 | Journal of Ocean University of China2016,15,3: | 1 |
