| 1 | Evaluation model for service life of dam based on time-varying risk probability显示文摘For many dam projects in China, the 50-year designed life time is coming to an end. It is urgent to study the theory and method to evaluate the dam service life. In this paper, firstly, the probability theory of fuzzy event and time-varying effect theory are used to analyze the time-variety of various risk factors in the process of dam operations. A method is proposed to quantify the above time-variety and a model to describe the fuzzy time-varying risk probability for the dam structure is also built. Secondly, the information entropy theory is used to analyze the uncertain degree relationship between the characteristic value of membership function and fuzzy risk probability, and a mathematical method is presented to calculate the time-varying risk probability accordingly. Thirdly, the relation mode between time-varying risk probability and service life is discussed. Based on this relation mode and the acceptable risk probability of dams in China, a method is put forward to evaluate and forecast the dam service life. Finally, the proposed theory and method are used to analyze one concrete dam. The dynamic variability and mutation feature of the dam risk probability are analyzed. The remaining service life of this dam is forecasted. The obtained results can provide technology support for the project management department to make treatment measures of engineering and reasonably arrange reinforce cost. The principles in this paper have wide applicability and can be used in risk analysis for slope instability and other fields. | SU HuaiZhi WEN ZhiPing HU Jiang WU ZhongRu | 2009 | Science China(Technological Sciences)2009,52,7: | 23 |

| 3 | High-resolution geochemistry records of climate changes since late-glacial from Dajiuhu peat in Shennongjia Mountains,Central China显示文摘A peat core with depths of 297 cm was obtained from the Dajiuhu Basin(31°29′27″N,109°59′45″E,1760 m)in Hubei Province,Central China.10 AMS ages provide a time control and reveal that this core spans the past about 16.0 kaBP(calibrated age)(1 4C age:13.3 kaBP).Multi-proxy indexes analysis of geochemistry shows the following character of climate and environmental changes since about 16 kaBP:(1) The climate during the late-glacial period was cold and wet as a whole,but fluctuated continually.11.4- 12.6 cal.kaBP,12.6-15.2 cal.kaBP and 15.2-16 kaBP were corresponding respectively to the Younger Drays,Bφlling-Allerφd Warm Period and the Oldest Drays.(2)Inheriting the some climate characteristics of the late-glacial,the climate during the early-Holocene was wet and temperature increased gradually,during which an obvious dry event around 10.6 cal.kaB appeared.(3)The climate during the mid-Holocene was genarally warm and wet.During 9.2-7.5 kaBP,temperature increased gradually, precipitation was less comparatively and the 8.2 kaBP cold event which might be representative in the globe was reflected markedly.Then,multi-proxy records were relatively stable during 6.7-4.2 kaBP, which shows the best water and thermal condition in the Holocene Optimum.(4)Around 4.2 kaBP,the climate and environment transform from warm and wet to cool and dry,which may result in the collapse of the Neolithic Culture and midwifery the civilization of Xia Dynasty in this region.After 0.9 kaBP,the climate turned cool and wet.Climate and environmental changes archived in Dajiuhu peat respond to the global changes since the late-glacial period and can be contrasted to the changes recorded in other high-resolution archives from the East Asia Monsoon region,which take on the variety model that the monsoon strengthened abruptly after the late-glacial,was strong during the early Holocene,subse- quently declined and became weak after the middle Holocene with dry climate.According to our analysis,the driving mechanism should be the response of solar radiation changes in the East Asia Monsoon region at middle latitudes. | MA ChunMei ZHU Cheng ZHENG ChaoGui WU ChunLin GUAN Yong ZHAO ZhiPing HUANG LinYan HUANG Run | 2008 | Chinese Science Bulletin2008,53,S1: | 19 |
| 4 | Counteraction of ABA-Mediated Inhibition of Seed Germination and Seedling Establishment by ABA Signaling Terminator in Arabidopsis显示文摘Seed germination and seedling establishment are important for the reproductive success of plants,but seeds and seedlings typically encounter constantly changing environmental conditions.By inhibiting seed germination and post-germinative growth through the PYR1/PYL/RCAR ABA receptors and PP2C co-receptors,the phytohormone abscisic acid(ABA)prevents premature germination and seedling growth under unfavorable conditions.However,little is known about how the ABA-mediated inhibition of seed germination and seedling establishment is thwarted.Here,we report that ABA Signaling Terminator(ABT),a WD40 protein,efficiently switches off ABA signaling and is critical for seed germination and seedling establishment.ABT is induced by ABA in a PYR1/PYL/RCAR-PP2C-dependent manner.Overexpression of ABT promotes seed germination and seedling greening in the presence of ABA,whereas knockout of ABT has the opposite effect.We found that ABT interacts with the PYR1/PYL/RCAR and PP2C proteins,interferes with the interaction between PYR1/PYL4 and ABI1/ABI2,and hampers the inhibition of ABI1/ABI2 by ABA-bound PYR1/PYL4,thereby terminating ABA signaling.Taken together,our results reveal a core mechanism of ABA signaling termination that is critical for seed germination and seedling establishment in Arabidopsis. | Zhijuan Wang Ziyin Ren Chunhong Cheng Tao Wang Hongtao Ji Yang Zhao Zhiping Deng Liya Zhi Jingjing Lu Xinying Wu Shimin Xu Mengmeng Cao Hongtao Zhao Liu Liu Jiankang Zhu Xia Li | 2020 | Molecular Plant2020,13,9: | 10 |
| 5 | A primary study of the correlation between the net air-sea heat flux and the interannual variation of western North Pacific tropical cyclone track and intensity显示文摘A singular value decomposition (SVD) analysis is carried out to reveal the relationship between the interannual variation of track and intensity of the western North Pacific tropical cyclones (WNPTCs) in the tropical cyclone (TC) active season (July-November) and the global net air-sea heat flux (Q net ) in the preceding season (April-June). For this purpose, a tropical cyclone track and intensity function (TIF) is defined by a combination of accumulated cyclone energy (ACE) index and a cyclone track density function. The SVD analysis reveals that the first mode is responsible for the positive correlation between the upward heat flux in the tropical central Pacific and the increased activity of western North Pacific (WNP) TIF, the second mode for the positive correlation between the upward heat flux in the North Indian Ocean and the northeastward track shift of WNPTCs and the third mode for the negative correlation between the upward heat flux in mid-latitude central Pacific and the northwest displacement of the WNP TC-active center. This suggests that Q net anomalies in some key regions have a substantial remote impact on the WNP TC activity. | WU Liang WEN Zhiping HUANG Ronghui | 2011 | Acta Oceanologica Sinica2011,30,6: | 9 |
| 6 | Geological characteristics and tectonic signifcance of unconformities in Mesoproterozoic successions in the northern margin of the North China Block显示文摘Several stratigraphic breaks and unconformities exist in the Mesoproterozoic successions in the northern margin of the North China Block.Geologic characters and spatial distributions of fve of these unconformities,which have resulted from different geological processes,have been studied.The unconformity beneath the Dahongyu Formation is interpreted as a breakup unconformity,representing the time of transition from continental rift to passive continental margin.The unconformities beneath the Gaoyuzhuang and the Yangzhuang formations are considered to be the consequence of regional eustatic fuctuations,leading to the exposure of highlands in passive margins during low sea-level stands and transgressive deposition on coastal regions during high sea-level stands.The unconformity atop the Tieling Formation might be caused by uplift due to contractional deformation in a back-arc setting,whereas the uplift after the deposition of the Xiamaling Formation might be attributed to a continental collision event.It is assumed that the occurrences of these unconformities in the Mesoproterozoic successions in the northern margin of the North China Block had a close bearing on the assemblage and breakup of the Columbia and Rodinia supercontinents. | Yongqiang Qu Jianguo Pan Shouxian Ma Zhiping Lei Lin Li Guoli Wu | 2014 | Geoscience Frontiers2014,5,1: | 7 |
| 7 | Ge-on-Si modulators operating at mid-infrared wavelengths up to 8 μm显示文摘We report mid-infrared Ge-on-Si waveguide-based PIN diode modulators operating at wavelengths of 3.8 and8 μm. Fabricated 1-mm-long electro-absorption devices exhibit a modulation depth of >35 dB with a 7 V forward bias at 3.8 μm, and a similar 1-mm-long Mach–Zehnder modulator has a Vπ· L of 0.47 V · cm. Driven by a 2.5 Vpp RF signal, 60 MHz on-off keying modulation was demonstrated. Electro-absorption modulation at 8 μm was demonstrated preliminarily, with the device performance limited by large contact separation and high contact resistance. | TIANTIAN LI MILOS NEDELJKOVIC NANNICHA HATTASAN WEI CAO ZHIBO QU CALLUM GLITTLEJOHNS JORDI SOLER PENADES LORENZO MASTRONARDI VINITA MITTAL DANIEL BENEDIKOVIC DAVID JTHOMSON FREDERIC YGARDES HEQUAN WU ZHIPING ZHOU GORAN ZMASHANOVICH | 2019 | Photonics Research2019,7,8: | 5 |

| 9 | Modeling CO_2 miscible flooding for enhanced oil recovery显示文摘The injection of fuel-generated CO2 into oil reservoirs will lead to two benefits in both enhanced oil recovery (EOR) and the reduction in atmospheric emission of CO2. To get an insight into CO2 miscible flooding performance in oil reservoirs, a multi-compositional non-isothermal CO2 miscible flooding mathematical model is developed. The convection and diffusion of CO2-hydrocarbon mixtures in multiphase fluids in reservoirs, mass transfer between CO2 and crude, and formation damages caused by asphaltene precipitation are fully considered in the model. The governing equations are discretized in space using the integral finite difference method. The Newton-Raphson iterative technique was used to solve the nonlinear equation systems of mass and energy conservation. A numerical simulator, in which regular grids and irregular grids are optional, was developed for predicting CO2 miscible flooding processes. Two examples of one-dimensional (1D) regular and three-dimensional (3D) rectangle and polygonal grids are designed to demonstrate the functions of the simulator. Experimental data validate the developed simulator by comparison with 1D simulation results. The applications of the simulator indicate that it is feasible for predicting CO2 flooding in oil reservoirs for EOR. | Ju Binshan Wu Yu-Shu Qin Jishun Fan Tailiang Li Zhiping | 2012 | Petroleum Science2012,9,2: | 5 |
| 10 | Effects of Rice-Fish Co-culture on Oxygen Consumption in Intensive Aquaculture Pond显示文摘Rice-fish co-culture has gained increasing attention to remediate the negative environmental impacts induced by intensive aquaculture. However, the effect of rice-fish co-culture on oxygen depletion has rarely been investigated. We constructed a rice-fish co-culture system in yellow catfish(Pelteobagrus fulvidraco) and freshwater shrimp(Macrobrachium nipponense) ponds using a new high-stalk rice variety, and conducted a field experiment to investigate the effect of rice-fish co-culture on water parameters and oxygen consumption. The results showed that rice-fish co-culture reduced the nutrients(total nitrogen, ammonia-N, total phosphorous and potassium) and the dissolved oxygen content in fish and shrimp ponds. However, they showed similar seasonal change of dissolved oxygen in the water of fish and shrimp ponds. Rice-fish co-culture reduced the total amount of oxygen consumption and optimized the oxygen consumption structure in pond. The respiration rates in water and sediment were significantly reduced by 66.1% and 31.7% in the catfish pond, and 64.4% and 38.7% in the shrimp pond, respectively, by additional rice cultivation. Rice-fish co-culture decreased the proportions of respiration in sediment and water, and increased the proportion of fish respiration. These results suggest that rice-fish co-culture is an efficient way to reduce hypoxia in intensive culture pond. | LI Fengbo SUN Zhiping QI Hangying ZHOU Xiyue XU Chunchun WU Dianxin FANG Fuping FENG Jinfei ZHANG Ning | 2019 | Rice science2019,26,1: | 4 |
| 11 | Development characteristics of the fault system and its control on basin structure, Bodong Sag, East China显示文摘The Bodong Sag,located in the Bohai Sea,offshore China,is one of the most petroliferous basins in China.Based on three dimensional seismic reflection data and time slice data,we analyze the fault system of the Bodong area in detail,establish the fault structure pattern of different types and summarize the distribution of the fault system.It is concluded that the development characteristics of the Cenozoic fault system are in accordance with the dextral stress field of the Tanlu Fault,which displayed a brush structure with NNE strike-slip faults as its principal faults,NE-trending extensional faults as secondary faults and EW-trending faults as minor faults.Faults can be divided into (1) strike-slip type,(2) extensional type,(3) strike-slip extensional type and (4) extensional strike-slip type.The spatial structures of different faults have obvious differences because of the fault properties and activity intensity.The fault system at different stages shows tremendous differences because of the transition of the Tanlu Fault from sinistral strike-slip to dextral strike-slip,the transition between extension and strike-slip,and the transition from mantle upwelling to thermal subsidence.According to the controlling effect of faults on basin structure,the Cenozoic basin experienced four evolutionary stages,(a) transition stage from sinistral strike-slip to dextral strike-slip,(b) strike-slip extensional faulted stage,(c) extensional strike-slip faulted stage and (d) strike-slip depression stage.The identification of temporal and spatial differences of faults could be used as a significant guideline for oil and gas exploration in the Bodong area. | Wu Zhiping Cheng Yanjun Yan Shiyong Su Wen Wang Xin Xu Changgui Zhou Xinhuai | 2013 | Petroleum Science2013,10,4: | 4 |

| 13 | Transverse mode instability mitigation in a high-power confined-doped fiber amplifier with good beam quality through seed laser control显示文摘In this work,a confined-doped fiber with the core/inner-cladding diameter of 40/250μm and a relative doping ratio of 0.75 is fabricated through a modified chemical vapor deposition method combined with the chelate gas deposition technique,and subsequently applied in a tandem-pumped fiber amplifier for high-power operation and transverse mode instability(TMI)mitigation.Notably,the impacts of the seed laser power and mode purity are preliminarily investigated through comparative experiments.It is found that the TMI threshold could be significantly affected by the seed laser mode purity.The possible mechanism behind this phenomenon is proposed and revealed through comprehensive comparative experiments and theoretical analysis.Finally,a maximum output power of 7.49 kW is obtained with the beam quality factor of approximately 1.83,which is the highest output power ever reported in a forward tandem-pumped confined-doped fiber amplifier.This work could provide a good reference and practical solution to improve the TMI threshold and realize high-power high-brightness fiber lasers. | Hanshuo Wu Haobo Li Yi An Ruixian Li Xiao Chen Hu Xiao Liangjin Huang Huan Yang Zhiping Yan Jinyong Leng Zhiyong Pan Pu Zhou | 2022 | High Power Laser Science and Engineering2022,10,6: | 3 |

| 15 | Organic–inorganic hybrid perovskite scintillators for mixed field radiation detection显示文摘Sensitive and fast detection of neutrons and gamma rays is vital for homeland security,high-energy physics,and proton therapy.Fast-neutron detectors rely on light organic scintillators,andγ-ray detectors use heavy inorganic scintillators and semiconductors.Efficient mixed-field detection using a single material is highly challenging due to their contradictory requirements.Here we report hybrid perovskites(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)that combine light organic cations and heavy inorganic skeletons at a molecular level to achieve unprecedented performance for mixed-field radiation detection.High neutron absorption due to a high density of hydrogen,strong radiative recombination within the highly confined[PbX_(6)]^(4-)layer,and sub-nanometer distance between absorption sites and radiative centers,enable a light yield of 41000 photons/MeV,detection pulse width of 2.97 ns and extraordinary linearity response toward both fast neutrons andγ-rays,outperforming commonly used fast-neutron scintillators.Neutron energy spectrum,time-of-flight based fast-neutron/γ-ray discrimination and neutron yield monitoring were all successfully achieved using(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)detectors.We further demonstrate the monitoring of reaction kinetics and total power of a nuclear fusion reaction.We envision that molecular hybridized scintillators open a new avenue for mixed-field radiation detection and imaging. | Mengling Xia Guangda Niu Linyue Liu Runlong Gao Tong Jin Pengying Wan Weicheng Pan Xianpeng Zhang Zuoxiang Xie Sam Teale Zenghua Cai Jiajun Luo Shan Zhao Haodi Wu Shiyou Chen Zhiping Zheng Qingguo Xie Xiaoping Ouyang Edward HSargent Jiang Tang | 2022 | InfoMat2022,4,9: | 2 |
| 16 | Intercellular adhesion molecule-5 protects PAJU cells during in vitro ischemia following cerebral infarction显示文摘BACKGROUND: Intercellular adhesion molecule-5 (ICAM-5) relieves the damage of beta-amyloid protein to PAJU cells. However, little is known about how ICAM-5 works as a neurotrophic factor, or whether ICAM-5 lessens neuronal damage under ischemic conditions following cerebral infarction. OBJECTIVE: To investigate the effects of ICAM-5 on PAJU cells growth in serum-free medium under ischemic conditions following cerebral infarction. DESIGN, TIME AND SETTING: The cytological in vitro study was performed at the Central Laboratory, Second Xiangya Hospital, Central South University, China, in June 2009. MATERIALS: Human ICAM-5 gene transfected into PAJU-TLN cells was supplied by the Life Science College, Helsinki University, Finland. Empty vector transfected PAJU-NEO cells were established by the Gene Center, Second Xiangya Hospital, Central South University, China. METHODS: PAJU-TLN cells transfected with human ICAM-5 or empty vector were incubated in serum-free medium. MAIN OUTCOME MEASURES: Phase contrast microscopy was used to observe changes in PAJU cell morphology. 3-(4, 5-dimethylthiazolzyl)-2, 5-diphenyltetrazolium bromide was used to determine cell viability. Hoechst 33258 was used to stain cell nuclei. Flow cytometry was utilized to measure the apoptosis rate of both PAJU-TLN and PAJU-NEO cells. RESULTS: Both PAJU-TLN and PAJU-NEO cells were injured by cultivating in serum-free medium, but the survival rate of PAJU-TLN cells was significantly higher. CONCLUSION: ICAM-5 protects PAJU-TLN cells from serum deprivation-induced apoptosis, induces the outgrowth of PAJU cells, and diminishes their morphologic impairment. | Weijun Zhou Heping Yang Xiang Wang Yi Peng Dapeng WU Xiaojie Zhang Zhiping Hu | 2010 | Neural Regeneration Research2010,5,3: | 2 |
| 17 | Alleviating the crosstalk effect via a fine-moulded light-blocking matrix for colour-converted micro-LED display with a 122% NTSC gamut显示文摘One of the major challenges when fabricating high gamut colour-converted micro-light-emitting diodes(LEDs)displays is severe crosstalk effect among adjacent pixels because of the wide view-angle feature of micro-LED chips.In this study,potential factors that contribute to the crosstalk effect were systematically simulated.We observed that precisely filling the space between each micro-LED chip with a light blocking matrix(LBM)can be a promising solution to alleviate this risk.After careful investigations,a press-assisted moulding technique was demonstrated to be an effective approach of fabricating the LBM.Nevertheless,experimental observations further revealed that residual black LBM on the surface of micro-LEDs severely reduces the brightness,thereby compromising the display performance.This problem was successfully addressed by employing a plasma etching technique to efficiently extract the trapped light.Eventually,a top-emitting blue micro-LED-based backlight fine-moulded with a black LBM was developed and combined with red and green quantum dot colour-conversion layers for full-colour display.The colour gamut of our manufactured display prototype can cover as high as 122%that of the National Television Standards Committee. | Yongming Yin Zhiping Hu Muhammad Umair Ali Miao Duan Yongwei Wu Ming Liu Wenxiang Peng Jun Hou Dongze Li Xin Zhang Hong Meng | 2022 | Light(Advanced Manufacturing)2022,3,3: | 2 |
| 18 | Hydraulic characteristics of converse curvature section and aerator in high-head and large discharge spillway tunnel显示文摘The hydraulic characteristics and cavitation erosion near the converse curvature section in the high-head and large discharge spillway tunnel have been important issues of concern to the hydropower project.In this paper,the evolutions of hydraulic elements such as pressure,flow velocity,wall shear stress,etc.in the converse curvature section are analyzed and the impacts of bottom aerator on hydraulic characteristics are discussed,with the commercial software FLUENT6.3 as a platform and combining the k-model and VOF method.The flow pattern in the converse curvature section of spillway tunnel is given by the three-dimensional numerical simulation.It indicates that the pressure changes rapidly with great pressure gradient from the beginning to the end of the curve.It also shows that the shear stress on side wall just downstream the end of the converse curvature curve is still increasing;the aeration cavity formed downstream the bottom aerator may cause the side wall pressure decreased to worsen the cavitation characteristics near the side wall.By means of the physical model experiment,the three-dimensional aerator composed of side wall baffling aerator and bottom aerator is studied,the baffling aerator suitable for the water flow conditions with water depth of 6.0 to 8.0 m and flow velocity of 35 to 50 m/s is proposed. | LIU ZhiPing 1,2,ZHANG Dong 2,ZHANG HongWei 2 &WU YiHong 1,2 1 State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin,Beijing 100038,China 2 China Institute of Water Resources and Hydropower Research,Beijing 100038,China | 2011 | Science China(Technological Sciences)2011,54,S1: | 2 |
