1Advances in studying interactions between aerosols and monsoon in China显示文摘Scientific issues relevant to interactions between aerosols and the Asian monsoon climate were discussed and evaluated at the 33 rd 'Forum of Science and Technology Frontiers' sponsored by the Department of Earth Sciences at the Chinese Academy of Sciences. Major results are summarized in this paper. The East Asian monsoon directly affects aerosol transport and provides a favorable background circulation for the occurrence and development of persistent fog-haze weather. Spatial features of aerosol transport and distribution are also influenced by the East Asian monsoon on seasonal, inter-annual, and decadal scales. High moisture levels in monsoon regions also affect aerosol optical and radiative properties. Observation analyses indicate that cloud physical properties and precipitation are significantly affected by aerosols in China with aerosols likely suppressing local light and moderate rainfall, and intensifying heavy rainfall in southeast coastal regions. However, the detailed mechanisms behind this pattern still need further exploration. The decadal variation in the East Asian monsoon strongly affects aerosol concentrations and their spatial patterns. The weakening monsoon circulation in recent decades has likely helped to increase regional aerosol concentrations. The substantial increase in Chinese air pollutants has likely decreased the temperature difference between land and sea, which favors intensification of the weakening monsoon circulation. Constructive suggestions regarding future studies on aerosols and monsoons were proposed in this forum and key uncertain issues were also discussed.WU GuoXiong LI ZhanQing FU CongBin ZHANG XiaoYe ZHANG RenYi ZHANG RenHe ZHOU TianJun LI JianPing LI JianDong ZHOU DeGang WU Liang ZHOU LianTong HE Bian HUANG RongHui 2016Science China Earth Sciences2016,59,1:16

3Numerical simulation of leading edge cavitation within the whole flow passage of a centrifugal pump显示文摘In this paper, the periodically unsteady pressure field and head-drop phenomenon caused by leading edge cavitation have been investigated numerically by computational fluid dynamics (CFD) in a single stage centrifugal pump. A CFD model for cavitation steady and unsteady simulation has been calculated using the k-ω SST turbulence model combining with a multiphase approach, based on a homogeneous model assumption. A truncated form of Rayleigh-Plesset equation is used as a source term for the inter-phase mass transfer. The CFD computational region includes the suction cone, impeller, side chambers and volute, as well as suction and pressure pipes. The results were compared with experimental data under non-cavitation and cavitation conditions and a good agreement was obtained for the global performance, the experimental data of the head and the efficiency are 34.04 m and 74.42% at BEP, respectively, the predicted head is 34.31 m and the predicted efficiency is 73.75%. The analysis of inner flow pattern shows that the vortex flow generation in the rear of cavity region is the main reason of the head-drop. Obvious increasing can be observed for the amplitude of the pressure fluctuation at the blade passing frequency with different cavitation situations, and subpeak can be found. Besides, the effects of unsteady flow in the side chambers cannot be neglected for accurately predicting the inner flow of the pump. These results imply that this numerical method is suitable for the cavitating flow in the pump.LI XiaoJun YUAN ShouQi PAN ZhongYong YUAN JianPing FU YanXia 2013Science China(Technological Sciences)2013,56,9:14
42018 update of expert consensus statement on antiplatelet therapy in East Asian patients with ACS or undergoing PCI显示文摘East Asians are the most populous race in the world and their health status is an important global issue.Compared with Caucasian populations, East Asian patients have a different benefit/risk ratio when using antithrombotic treatment. Despite this observation, treatment strategies in East Asian patients are mostly based on the American and European guidelines. Despite a lower platelet inhibitory response to clopidogrel, East Asian patients show a similar or even a lower rate of ischemic event occurrence and higher bleeding risk compared with Caucasian patients. For potent P2Y_(12) inhibitors(ticagrelor and prasugrel),East Asian patients have shown less favorable net clinical benefits compared with Caucasian patients,which may be related to differences in pharmacokinetic/pharmacodynamic profiles and therapeutic zone of antiplatelet effect. This updated consensus mainly focuses on state-of-the-art and current controversies in the East Asian population. In addition, when East Asian patients are administered potent P2Y_(12) receptor inhibitors, the strategies and ongoing trials to overcome the related hurdles are discussed.Yong Huo Young-Hoon Jeong Yanjun Gong Daowen Wang Ben He Jiyan Chen Guosheng Fu Yundai Chen Jianping Li Yi Li Shinya Goto Udaya S.Tantry Paul A.Gurbel Jong-Hwa Ahn Hyo-Soo Kim Myung Ho Jeong Yaling Han Sidney C.Smith Jr. Junbo Ge 2019Science Bulletin2019,64,3:12
5A Dormant Multi-Controller Model for Software Defined Networking显示文摘In order to improve the scalability and reliability of Software Defined Networking(SDN),many studies use multiple controllers to constitute logically centralized control plane to provide load balancing and fail over.In this paper,we develop a flexible dormant multi-controller model based on the centralized multi-controller architecture.The dormant multi-controller model allows part of controllers to enter the dormant state under light traffic condition for saving system cost.Meanwhile,through queueing analysis,various performance measures of the system can be obtained.Moreover,we analyze the real traffic of China Education Network and use the results as the parameters of computer simulation and verify the effects of parameters on the system characteristics.Finally,a total expected cost function is established,and genetic algorithm is employed to find the optimal values of various parameters to minimize system cost for the deployment decision making.FU Yonghong BI Jun WU Jianping CHEN Ze WANG Ke LUO Min 2014China Communications2014,11,3:11

7Simulation and Experimental Investigation of Jetting Penetrator Charge at Large Stand-off Distance显示文摘In order to study and apply the penetration performance of jetting penetrator charge at long stand-off distance, three jetting penetrator charges(JPC), including spherical cone liner, truncated wide-angle liner and spherical segment liner, are designed. The numerical simulation analysis of the formation, elongation and penetration processes of rod-like jet is conducted by using LS-DYNA software. And the penetrating test is carried out at long stand-off distance. The test results show that the rod-like jet formed by the optimized spherical segment liner can pierce through a 90mm thick 45# steel target at 20 charge diameters(CD) stand-off distance when the charge detonation mode is a central point initiation, and the penetration depth can be up to 1.6CD. It is concluded that, at 20 CD stand-off distance, the penetration performance of JPC with spherical segment liner is the best, that of truncated wide-angle liner takes second place, and that of spherical cone liner is the worst.FU Jianping CHEN Zhigang HOU Xiucheng LI Shuqiang LI Shoucang WANG Jingwen 2013Defence Technology(防务技术)2013,9,2:9
8Aerosol characteristics and impacts on weather and climate over the Tibetan Plateau显示文摘With themostmassive snow and ice globally between 60°S and 60°S ,the Tibetan Plateau(TP),also called the third pole of the world,plays significant roles in the weather,climate and lives in South Asia and East Asia and even the world[1–3].Investigating the variation of weather and the climate system over the TP has long been carried out,which is significant for fresh water supplies for over 1.4 billion people in Asia.Actually,the‘Third Pole Environment’program was initiated to call international efforts to understand both climate and environment changes on the plateau[1],which has already shown rapid warming and intensified cryospheric melt and water cycle.Chuanfeng Zhao Yikun Yang Hao Fan Jianping Huang Yunfei Fu Xiaoye Zhang Shichang Kang Zhiyuan Cong Husi Letu Massimo Menenti 2020National Science Review2020,7,3:7
9Interactive effects of understory removal and fertilization on soil respiration in subtropical Eucalyptus plantations显示文摘Aims It has been well recognized that understory vegetation plays an important role in driving forest ecosystem processes and functioning.In subtropical plantation forests,understory removal and fertiliza-tion have been widely applied;however,our understanding on how understory removal affects soil respiration and how the process is regulated by fertilization is limited.Here,we conducted an under-story removal experiment combined with fertilization to evaluate the effects of the two forest management practices and their inter-actions on soil respiration in subtropical forest in southern China.Methods The study was conducted in a split-plot design with fertilization as the whole-plot factor,understory removal as the subplot factor and block as the random factor in subtropical Eucalyptus plantations.In total,there were four treatments:control with unfertilized and intact understory(CK),understory removal but without fertilization(UR),with fertilization but without understory removal(FT)and with fertilization+understory removal(FT+UR).Eucalyptus above-and belowground biomass increment,fine root biomass,soil tempera-ture,soil moisture and soil respiration were measured in the present study.understory respiration(Ru)was quantified in different ways:Ru=RCK−Ru or Ru=RFT−R(FT+u);fertilization increased soil respiration(RFI)was also quantified in different ways:RFI=RFT−RCK or RFI=R(FT+u)−Ru.Important Findingsover a 2-year experiment,our data indicate that understory removal significantly decreased soil respiration,while fertilization increased soil respiration.understory removal decreased soil respiration by 28.8%under fertilization,but only 15.2%without fertilization.Fertilization significantly increased soil respiration by 23.6%with the presence of understory vegetation,and only increased by 3.7%when understory was removed,indicating that fertilization increased soil respiration mainly by increasing the contribution of the understory.our study advances our understanding of the interactive effects of understory management and fertilization on soil respiration in subtropical plantations.Songze Wan Chenlu Zhang Yuanqi Chen Jie Zhao Xiaolin Zhu Jianping Wu Lixia Zhou Yongbiao Lin Zhanfeng Liu Shenglei Fu 2015Journal of Plant Ecology2015,8,3:6

11The rational design of multiple molecular module-based assemblies for simultaneously improving rice yield and grain quality显示文摘Rice is one of the most important staple food for over half of the world's population,and a substantial increase in productivity and quality of rice grain will be required to feed a growing human population.Grain size and shape are the two important components contributing to grain yield and quality,because they impact both yield potential and end-use quality.Over the past 50 years。Kun Wu Xiaopeng Xu Nan Zhong Haixiang Huang Jianping Yu Yafeng Ye Yuejin Wu Xiangdong Fu 2018Journal of Genetics and Genomics2018,45,6:4
12Repeated febrile convulsions impair hippocampal neurons and cause synaptic damage in immature rats: neuroprotective effect of fructose-1,6-diphosphate显示文摘Fructose-1,6-diphosphate is a metabolic intermediate that promotes cell metabolism. We hypothesize that fructose-1,6-diphosphate can protect against neuronal damage induced by febrile convulsions. Hot-water bathing was used to establish a repetitive febrile convulsion model in rats aged 21 days, equivalent to 3–5 years in humans. Ninety minutes before each seizure induction, rats received an intraperitoneal injection of low- or high-dose fructose-1,6-diphosphate(500 or 1,000 mg/kg, respectively). Low- and high-dose fructose-1,6-diphosphate prolonged the latency and shortened the duration of seizures. Furthermore, high-dose fructose-1,6-diphosphate effectively reduced seizure severity. Transmission electron microscopy revealed that 24 hours after the last seizure, high-dose fructose-1,6-diphosphate reduced mitochondrial swelling, rough endoplasmic reticulum degranulation, Golgi dilation and synaptic cleft size, and increased synaptic active zone length, postsynaptic density thickness, and synaptic interface curvature in the hippocampal CA1 area. The present findings suggest that fructose-1,6-diphosphate is a neuroprotectant against hippocampal neuron and synapse damage induced by repeated febrile convulsion in immature rats.Jianping Zhou Fan Wang Jun Zhang Hui Gao Yufeng Yang Rongguo Fu 2014Neural Regeneration Research2014,9,9:4

15Application of Grey Associative Analysis to the Assessment of Regional Water Security显示文摘The assessment of water security is an important content in the security management of water resources due to the fact that the state of water security directly affects both the sustainable development of regional economy and the improvement on the living quality of mankind. Grey associative analysis is introduced and applied to assessment of water security on the basis of grey characteristics of the assessment index system of water security. As a case study shows, grey associative analysis is used for evaluating water security of some provinces in China, and the satisfactory assessment results are obtained. The sequence of provinces in China with regard to water security from good to poor is obtained and, moreover, the water security level of each region is also confirmed. The results obtained accord with the actual state of each region. They are of practical significance and can be used to guide the management of regional water security and a sustainable development of the economy therein. At the same time, the results demonstrate that grey associative analysis provides a new method for assessing waterZhang Yanmin~1, Dong Qianjin~1, Wang Xianjia~1, Wang Jianping~2, Fu Chun~3(1.State Key Laboratory of Water Resources and Hydropower Engineering Science, Wuhan University, Wuhan 430072, China 2.College of Economics and Management, China Three Gorges University, Yichang 443002, China 3.

16Characterization and Proteomic Analysis of Novel Rice Lesion Mimic Mutant with Enhanced Disease Resistance显示文摘Lesion mmic mutants(LMMs)are plants that spontaneously form lesions without pathogeninfection or external stimulus and exhibit resistance to pathogens.Here,a rice LMM was created by ethylmethane sulfonate mutagenesis,named as hpil(hydrogen peroxide induced lesion).Diaminobenzidineand trypan blue staining showed that large amounts of H_(2)O_(2) were produced and cell death was occurredat and around the parts of lesion mimic in the rice leaves.The phenotype of hpil is controlled by a singlerecessive gene,localized at a 2 Mb interval on chromosome 2.The data suggested that hpil is a novelLMM with enhanced bacterial and fungal disease resistance,and multiple pathogenesis-related proteins(PRs)were up-regulated.The proteomes of leaves at three positions(different degrees of lesion mimicseverity)were characterized in hpil compared with its wild type plant.Differentially expressed proteinswere detected by two dimensional difference gel electrophoresis and 274 proteins were identified byMALDITOF/TOFTM.These proteins were related to metabolic process,cellular process and response tostimulus,with mostly down-regulated in hpil leaves.Many of these proteins were related to the Calvincycle,photosynthetic electron transport chain,glycolysis/gluconeogenesis and phosphonates pathways.Some resistance-related proteins including 14-3-3 proteins,OsPR10 and antioxidases such asperoxidase,superoxide dismutase and ascorbate peroxidase were up-regulated in leaves with lesionmimic.These results provide the foundation for cloning of the target gene and shed light on themechanism involved in autaimmunity of rice.Yang Yong Lin Qiujun Chen Xinyu Liang Weifang Fu Yuwen Xu Zhengjin Wu Yuanhua Wang Xuming Zhou Jie Yu Chulang Yan Chengqi Mei Qiong Chen Jianping 2021Rice science2021,28,5:2
17Formation and Optical Properties of ZnO:ZnFe_(2)O_(4) Superlattice Microwires显示文摘Pure ZnO hexagonal microwires and Fe(Ⅲ)-doped ZnO microwires(MWs)with a novel rectangular cross section were synthesized in a confined chamber by a convenient one-step thermal evaporation method.An oriented attachment mechanism is consistent with a vapor-solid growth process.Photoluminescence(PL)and Raman spectroscopy of the Fe(Ⅲ)-doped ZnO MWs and in situ spectral mappings indicate a quasi-periodic distribution of Fe(Ⅲ)along a one-dimensional(1-D)superlattice ZnO:ZnFe_(2)O_(4) wire,while PL mapping shows the presence of optical multicavities and related multimodes.The PL spectra at room temperature show weak near-edge doublets(376 nm and 383 nm)and a broad band(450-650 nm)composed of strong discrete lines,due to a 1-D photonic crystal structure.Such a 1-D coupled optical cavity material may find many applications in future photonic and spintronic devices.Yun Li Guozhang Dai Chunjiao Zhou Qinglin Zhang Qiang Wan Limin Fu Jianping Zhang Ruibin Liu Chuanbao Cao Anlian Pan Yunhong Zhang Bingsuo Zou 2010Nano Research2010,3,5:2

19Balancing selection and wild gene pool contribute to resistance in global rice germplasm against planthopper显示文摘Interactions and co-evolution between plants and herbivorous insects are critically important in agriculture.Brown planthopper(BPH)is the most severe insect of rice,and the biotypes adapt to feed on different rice genotypes.Here,we present genomics analyses on 1,520 global rice germplasms for resistance to three BPH biotypes.Genome-wide association studies identified 3,502 single nucleotide polymorphisms(SNPs)and 59 loci associated with BPH resistance in rice.We cloned a previously unidentified gene Bph37 that confers resistance to BPH.The associated loci showed high nucleotide diversity.Genome-wide scans for trans-species polymorphisms revealed ancient balancing selection at the loci.The secondarily evolved insect biotypes II and III exhibited significantly higher virulence and overcame more rice varieties than the primary biotype I.In response,more SNPs and loci evolved in rice for resistance to biotypes II and III.Notably,three exceptional large regions with high SNP density and resistance-associated loci on chromosomes 4 and 6 appear distinct between the resistant and susceptible rice varieties.Surprisingly,these regions in resistant rice might have been retained from wild species Oryza nivara.Our findings expand the understanding of long-term interactions between rice and BPH and provide resistance genes and germplasm resources for breeding durable BPH-resistant rice varieties.Cong Zhou Qian Zhang Yu Chen Jin Huang Qin Guo Yi Li Wensheng Wang Yongfu Qiu Wei Guan Jing Zhang Jianping Guo Shaojie Shi Di Wu Xiaohong Zheng Lingyun Nie Jiaoyan Tan Chaomei Huang Yinhua Ma Fang Yang Xiqin Fu Bo Du Lili Zhu Rongzhi Chen Zhikang Li Longping Yuan Guangcun He 2021Journal of Integrative Plant Biology2021,63,10:2
