| 1 | Three-dimensional path planning for unmanned aerial vehicle based on interfered fluid dynamical system显示文摘This paper proposes a method for planning the three-dimensional path for low-flying unmanned aerial vehicle(UAV) in complex terrain based on interfered fluid dynamical system(IFDS) and the theory of obstacle avoidance by the flowing stream. With no requirement of solutions to fluid equations under complex boundary conditions, the proposed method is suitable for situations with complex terrain and different shapes of obstacles. Firstly, by transforming the mountains, radar and anti-aircraft fire in complex terrain into cylindrical, conical, spherical, parallelepiped obstacles and their combinations, the 3D low-flying path planning problem is turned into solving streamlines for obstacle avoidance by fluid flow. Secondly, on the basis of a unified mathematical expression of typical obstacle shapes including sphere, cylinder, cone and parallelepiped, the modulation matrix for interfered fluid dynamical system is constructed and 3D streamlines around a single obstacle are obtained. Solutions to streamlines with multiple obstacles are then derived using weighted average of the velocity field. Thirdly, extra control force method and virtual obstacle method are proposed to deal with the stagnation point and the case of obstacles' overlapping respectively. Finally, taking path length and flight height as sub-goals, genetic algorithm(GA) is used to obtain optimal 3D path under the maneuverability constraints of the UAV. Simulation results show that the environmental modeling is simple and the path is smooth and suitable for UAV. Theoretical proof is also presented to show that the proposed method has no effect on the characteristics of fluid avoiding obstacles. | Wang Honglun Lyu Wentao Yao Peng Liang Xiao Liu Chang | 2015 | Chinese Journal of Aeronautics2015，28，1： | 27 |
| 2 | Long-term cycles in the carbon reservoir of the Quaternary ocean: a perspective from the South China Sea显示文摘In recent years,long-term,high-resolution records from the deep sea and ice-cores have ofered new research opportunities for Quaternary science.Paleoclimate studies are no longer restricted to individual glacial cycles,but extend to long-term(≥105 yr)processes across those cycles.Ocean Drilling Program Leg 184 of the South China Sea in 1999 uncovered well-preserved sediment sections,in which three long-term cycles in Pleistocene carbon isotope(δ13C)sequence have been found and demonstrated to be common in the global ocean.Subsequent discoveries conirm the existence of long-term processes of 105yr in both the hydrologic(ice-sheet changes)and carbon(biogeochemical changes)cycles,posing the question whether the two processes are related.he present review shows that the long-eccentricity cycles prevail throughout theδ13C and other biogeochemical records in geologic history,and 400-kyr cycles in the oceanicδ13C sequence before the Quaternary can be hypothetically explained by changes in ratio between particulate and dissolved organic carbon(POC/DOC)in the ocean,depending on the monsoon-controlled nutrient supply.his is a‘DOC hypothesis’.However,ocean restructuring at 1.6 Ma marked by the isolation of a sluggish abyss under the Southern Ocean has obscured the long-eccentricity 400-kyr signal in oceanicδ13C.he last million-year period has experienced two major changes in the climate regime,namely the mid-Pleistocene transition(MPT)centered at 0.9 Ma and the mid-Brunhes event(MBE)around 0.4 Ma.he MPT and MBE were preluded byδ13C maxima-III(δ13Cmax-III)~1.0 Ma andδ13Cmax-II~0.5 Ma,respectively.Together with similar hydroclimatic phenomena over corresponding glacial cycles,the two groups of hydrologic and biogeochemical events appear to have been driven largely by oceanographic changes in the Southern Ocean.herefore,we interpret that the long-term biogeochemical processes originating from the Southern Ocean must have played a crucial role in Quaternary ice-sheet waxing and waning. | PinXian Wang QianYu Li Jun Tian ZhiMin Jian ChuanLian Liu Li Li WenTao Ma | 2014 | National Science Review2014，1，1： | 23 |
| 3 | Effect of exposure to ambient PM2.5 pollution on the risk of respiratory tract diseases: a meta-analysis of cohort studies显示文摘The International Agency for Research on Cancer and the World Health Organization have designated airborne particulates,including particulates of median aerodynamic diameter < 2.5um(PM_(2.5)),as Group 1 carcinogens.It has not been determined,however,whether exposure to ambient PM_(2.5) is associated with an increase in respiratory related diseases.This meta-analysis assessed the association between exposure to ambient fine particulate matter(PM_(2.5)) and the risk of respiratory tract diseases,using relevant articles extracted from PubMed,Web of Science,and Embase.In results,of the 1,126 articles originally identified,35(3.1%) were included in this meta-analysis.PM_(2.5)was found to be associated with respiratory tract diseases.After subdivision by age group,respiratory tract disease,and continent,PM_(2.5) was strongly associated with respiratory tract diseases in children,in persons with cough,lower respiratory illness,and wheezing,and in individuals from North America,Europe,and Asia.The risk of respiratory tract diseases was greater for exposure to traffic-related than non-traffic-related air pollution.In children,the pooled relative risk(RR) represented significant increases in wheezing(8.2%),cough(7.5%),and lower respiratory illness(15.3%).The pooled RRs in children were 1.091(95%CI:1.049,1.135) for exposure to<25 μg/m^3 PM_(2.5),and 1.126(95%CI:1.067,1.190) for exposure to > 25 μg/m^3 PM_(2.5).In conclusion,exposure to ambient PM_(2.5) was significantly associated with the development of respiratory tract diseases,especially in children exposed to high concentrations of PM_(2.5). | Qian Liu Cheng Xu Guixiang Ji Hui Liu Wentao Shao Chunlan Zhang Aihua Gu Peng Zhao | 2017 | The Journal of Biomedical Research2017，31，2： | 16 |
| 4 | Biofunctional magnesium coated Ti6Al4V scaffold enhances osteogenesis and angiogenesis in vitro and in vivo for orthopedic application显示文摘The insufficient osteogenesis and osseointegration of porous titanium based scaffold limit its further application.Early angiogenesis is important for scaffold survival.It is necessary to develop a multifunctional surface on titanium scaffold with both osteogenic and angiogenic properties.In this study,a biofunctional magnesium coating is deposited on porous Ti6Al4V scaffold.For osseointegration and osteogenesis analysis,in vitro studies reveal that magnesium-coated Ti6Al4V co-culture with MC3T3-E1 cells can improve cell proliferation,adhesion,extracellular matrix(ECM)mineralization and ALP activity compared with bare Ti6Al4V cocultivation.Additionally,MC3T3-E1 cells cultured with magnesium-coated Ti6Al4V show significantly higher osteogenesisrelated genes expression.In vivo studies including fluorochrome labeling,micro-computerized tomography and histological examination of magnesium-coated Ti6Al4V scaffold reveal that new bone regeneration is significantly increased in rabbits after implantation.For angiogenesis studies,magnesium-coated Ti6Al4V improve HUVECs proliferation,adhesion,tube formation,wound-healing and Transwell abilities.HUVECs cultured with magnesium-coated Ti6Al4V display significantly higher angiogenesis-related genes(HIF-1αand VEGF)expression.Microangiography analysis reveal that magnesium-coated Ti6Al4V scaffold can significantly enhance the blood vessel formation.This study enlarges the application scope of magnesium and provides an optional choice to the conventional porous Ti6Al4V scaffold with enhanced osteogenesis and angiogenesis for further orthopedic applications. | Peng Gao Bo Fan Xiaoming Yu Wenwen Liu Jie Wu Lei Shi Di Yang Lili Tan Peng Wan Yulin Hao Shujun Li Wentao Hou Ke Yang Xiaokang Li Zheng Guo | 2020 | Bioactive Materials2020，5，3： | 15 |
| 5 | The effects of Xingnao Jieyu capsules on post-stroke depression are similar to those of fluoxetine显示文摘The Xingnao Jieyu capsule has been shown to effectively relieve neurologic impairments and lessen depression. It remains poorly understood whether this capsule can be used to treat post-stroke depression. Thus, in the present study, we established a rat model of post-stroke depression using left middle cerebral artery occlusions in combination of chronic unpredictable stress and solitary housing during development. Experimental rats received intragastric perfusion with 0.82, 0.41, and 0.20 g/kg Xingnao Jieyu capsules separately dissolved in 2 mL distilled water. Fluoxetine served as a positive control. The treatment was conducted over 28 days. Sugar water consumption test, open-field test, real-time fluorescent quantitative PCR and immunohistochemical staining results demonstrated that intragastric perfusion with various doses of Xingnao Jieyu capsules increased sugar water consumption, voluntary behaviors and synaptotagmin mRNA and protein expression in rats with post-stroke depression. These therapeutic effects were similar to those of fluoxetine. These results indicate that Xingnao Jieyu capsules upregulate synaptotagmin expression in hippocampi of rats with post-stroke depression, and exert antidepressant effects. | Yongmei Yan Wentao Fan Li Liu Ru Yang Wenjia Yang | 2013 | Neural Regeneration Research2013，8，19： | 13 |

| 8 | Electron Beam Melted Beta-type Ti–24Nb–4Zr–8Sn Porous Structures With High Strength-to-Modulus Ratio显示文摘Electron beam melting(EBM)has been used to manufactureβ-type Ti–24Nb–4Zr–8Sn porous components with 70%porosity.EBM-produced components have favorable structural features(i.e.smooth strut surfaces,fewer defects)and an(α+β)-type microstructure,similar to that subjected to aging treatment.EBM-produced components exhibit more than twice the strength-to-modulus ratio of porous Ti–6Al–4V components having the same porosity.The processing–microstructure–property relationship and deformation behavior of EBM-produced components are discussed in detail.Such porous titanium components composed of non-toxic elements and having high strength-to-modulus ratio are highly attractive for biomedical applications. | Yujing Liu Shujun Li Wentao Hou Shaogang Wang Yulin Hao Rui Yang Timothy B.Sercombe Lai-Chang Zhang | 2016 | Journal of Materials Science & Technology2016，32，6： | 9 |

| 10 | The localization of type 2 diabetes susceptibility gene loci in northern Chinese Han families显示文摘We conducted a genome-wide scan, in which 358 well distributed fluorescent dye-labeled microsatellite marker sets were applied in 32 Chinese Han type 2 diabetes families from Northern China to search for the susceptibility gene loci. The data collected from screening all the chromosomes of genome were genotyped by using genescan and genotyping software, then, parametric and non-parametric multipoint test, and affected sib-pair analysis as well, were used to analyze the data. We identified some susceptibility gene loci residing in chromosomes 1,12,18,20, respectively, or precisely, located around D1S214, D1S207, D1S218, D1S235, D12S336, D18S61 and D20S118. The comparison of this result with those from other regions and races reflected the complexity and heterogeneity of type 2 diabetes. | ZHAO Jinying WANG Heng XIONG Momiao HUANG Wei ZUO Jin CHEN Zhu QIANG Boqin SUN Qi LI Yuxiu LIU Qiuying DU Weinan CHEN Jialun DING Wei YUAN Wentao ZHAO Yang XU Hongyan JIN Li FANG Fude | 2000 | Chinese Science Bulletin2000，45，19： | 8 |
| 11 | Sensitivity-enhanced surface plasmon resonance sensor utilizing a tungsten disulfide (WS_2) nanosheets overlayer显示文摘Tungsten disulfide(WS_2), as a representative layered transition metal dichalcogenide(TMDC) material, possesses important potential for applications in highly sensitive sensors. Here, a sensitivity-enhanced surface plasmon resonance(SPR) sensor with a metal film modified by an overlayer of WS_2 nanosheets is proposed and demonstrated. The SPR sensitivity is related to the thickness of the WS_2 overlayer, which can be tailored by coating a WS_2 ethanol suspension with different concentrations or by the number of times of repeated post-coating.Benefitting from its large surface area, high refractive index, and unique optoelectronic properties, the WS_2 nanosheet overlayer coated on the gold film significantly improves the sensing sensitivity. The highest sensitivity(up to 2459.3 nm∕RIU) in the experiment is achieved by coating the WS_2 suspension once. Compared to the case without a WS_2 overlayer, this result shows a sensitivity enhancement of 26.6%. The influence of the WS_2 nanosheet overlayer on the sensing performance improvement is analyzed and discussed. Moreover, the proposed WS_2 SPR sensor has a linear correlation coefficient of 99.76% in refractive index range of 1.333 to 1.360. Besides sensitivity enhancement, the WS_2 nanosheet overlayer is able to show additional advantages, such as protection of metal film from oxidation, tunability of the resonance wavelength region, biocompatibility, capability of vapor,and gas sensing. | HAO WANG HUI ZHANG JIANGLI DONG SHIQI HU WENGUO ZHU WENTAO QIU HUIHUI LU JIANHUI YU HEYUAN GUAN SHECHENG GAO ZHAOHUI LI WEIPING LIU MIAO HE JUN ZHANG ZHE CHEN YUNHAN LUO | 2018 | Photonics Research2018，6，6： | 8 |
| 12 | Conductive Polyaniline/Cellulose/Graphite Composite Films with High Thermal Stability and Antibacterial Activity显示文摘Functional composite films were successfully prepared from cellulose, graphite(GP), and polyaniline(PANI) using a combination of physical and chemical processes. Cellulosewasdissolved in N-methylmorpholine-N-oxide monohydrate(NMMO) and regenerated in water to form the matrix. GP was dispersed in the NMMO solvent prior to the dissolution of the cellulose, and PANI was deposited on the surfaces of the cellulose/GP films by in situ chemical polymerization. The structures of the PANI/cellusose/GP composite films were investigated using X-ray diffraction analysis, Fourier transform infrared spectroscopy, scanning electron microscopy(SEM), and SEM/energy-dispersive X-ray spectroscopy. The mechanical strengths, thermal stabilities, conductivities, and antibacterial activities of the films were studied in detail. The results showed that GP formed a multilayered structure in the cellulose matrix and that the PANI nanoparticles were tightly wrapped on the film surface. The film thickness increased from 40 mm to 100 mm after the addition of GP and PANI. The tensile strength of the composite films was 80~107 MPa, with the elongation at break being 3%~10%. The final residual weight of the composite films was as high as 65%, and the conductivity of the composite films reached 14.36 S/m. The cellulose matrix ensured that the films were flexible and exhibited desirable mechanical properties, while the GP filler significantly improved the thermal stability of the films. The PANI coating acted as a protective layer during burning and provided good electrical conductivity and antibacterial activity against Escherichia coli; both of these characteristics were slightly enhanced by the incorporation of GP. These PANI/cellulose/GP composite films should be suitable for use in electronics, antistatic packing, and numerous other applications. | JingHuan Chen JinGang Liu WenTao Zhang Kun Wang XueRen Qian RunCang Sun | 2017 | Paper And Biomaterials2017，2，1： | 7 |

| 14 | Mammalian ALKBH1 serves as an N^6-mA demethylase of unpairing DNA显示文摘N^6-methyladenine(N^6-mA)of DNA is an emerging epigenetic mark in mammalian genome.Levels of N^6-mA undergo drastic fluctuation during early embryogenesis,indicative of active regulation.Here we show that the 2-oxoglutarate-dependent oxygenase ALKBH1 functions as a nuclear eraser of N^6-mA in unpairing regions(e.g.,SIDD,Stress-Induced DNA Double Helix Destabilization regions)of mammalian genomes.Enzymatic profiling studies revealed that ALKBH1 prefers bubbled or bulged DNAs as substrate,instead of single-stranded(ss-)or double-stranded(ds-)DNAs.Structural studies of ALKBH1 revealed an unexpected“stretch-out”conformation of its“Flip1”motif,a conserved element that usually bends over catalytic center to facilitate substrate base flipping in other DNA demethylases.Thus,lack of a bending“Flip1”explains the observed preference of ALKBH1 for unpairing substrates,in which the flipped N^6-mA is primed for catalysis.Co-crystal structural studies of ALKBH1 bound to a 21-mer bulged DNA explained the need of both flanking duplexes and a flipped base for recognition and catalysis.Key elements(e.g.,an ALKBH1-specificα1 helix)as well as residues contributing to structural integrity and catalytic activity were validated by structurebased mutagenesis studies.Furthermore,ssDNA-seq and DIP-seq analyses revealed significant co-occurrence of base unpairing regions with N^6-mA in mouse genome.Collectively,our biochemical,structural and genomic studies suggest that ALKBH1 is an important DNA demethylase that regulates genome N^6-mA turnover of unpairing regions associated with dynamic chromosome regulation. | Min Zhang Shumin Yang Raman Nelakanti Wentao Zhao Gaochao Liu Zheng Li Xiaohui Liu Tao Wu Andrew Xiao Haitao Li | 2020 | Cell Research2020，30，3： | 6 |
| 15 | The mass-balance characteristics and sensitivities to climate variables of Laohugou Glacier No.12,western Qilian Mountains,China显示文摘Due to global warming, glaciers on the Tibetan Plateau(TP) are experiencing widespread shrinkage; however, the mechanisms controlling glacier variations across the TP are still rather unclear, especially on the northeastern TP. In this study, a physically based, distributed surface-energy and mass-balance model was used to simulate glacier mass balance forced by meteorological data. The model was applied to Laohugou No. 12 Glacier, western Qilian Mountains, China, during2010~2012. The simulated albedo and mass balance were validated and calibrated by in situ measurements. The simulated annual glacier-wide mass balances were-385 mm water equivalent(w.e.) in 2010/2011 and-232 mm w.e. in 2011/2012,respectively. The mean equilibrium-line altitude(ELA) was 5,015 m a.s.l., during 2010~2012, which ascended by 215 m compared to that in the 1970 s. The mean accumulation area ratio(AAR) was 39% during the two years. Climatic-sensitivity experiments indicated that the change of glacier mass balance resulting from a 1.5 °C increase in air temperature could be offset by a 30% increase in annual precipitation. The glacier mass balance varied linearly with precipitation, at a rate of130 mm w.e. per 10% change in total precipitation. | JiZu Chen ShiChang Kang Xiang Qin WenTao Du WeiJun Sun YuShuo Liu | 2017 | Research in Cold and Arid Regions2017，9，6： | 6 |
| 16 | Effects of stick-slip on stress intensity factors for subsurface short cracks in rolling contact显示文摘This paper theoretically investigates the effects of stick-slip in rolling contact zone on stress intensity factors(SIFs)for subsurface short cracks.New mathematical models for SIFs including stick-slip ratio are deduced in two cases.One is a subsurface short crack parallel to surface,and the numerical analysis shows that the value of KⅡincreases with the increase of stick-slip ratio;the other is a subsurface short crack perpendicular to the surface,and the numerical analysis indicates that the positive value of KⅠdecreases with the increase of stick-slip ratio.As △KⅠand △KⅡare necessary to evaluate the fatigue crack propagation rate or fatigue lifetime,the influences of stick-slip ratio on them are then discussed.It is found that the maximum variations of △KⅠand △KⅡare both around 3.0%due to stick-slip ratio variation. | LIU WenTao ZHANG Yun FENG ZhiJing ZHAO JingShan | 2013 | Science China(Technological Sciences)2013，56，10： | 6 |
| 17 | Response of the sediment geochemistry of the Changjiang River(Yangtze River) to the impoundment of the Three Gorges Dam显示文摘Based on the measurement of major and trace elements in suspended sediments in the low reaches of the Changjiang River during throughout a whole hydrologic year, the origins, seasonal variations, and fluxes of multielements and the human impacts on multielements transport processes have been analyzed along with the influence of weathering in the Changjiang River basin. The results show that most element contents were high in both autumn and winter and low in summer, which was largely caused by the dilution of discharge. Weathering detritus in the Changjiang River basin is the main source of most elements in suspended sediments. However, riverine pollution could bring more loadings of Cd, Pb, As and Zn into river water than it did a few decades ago. The annual average fluxes of Cd, Pb and Zn, which are major contamination elements, to the sea were 179 ± 21 tons/year, 7810 ± 675 tons/year, and 12,000 ± 1320 tons/year,respectively, in which approximately 8.7%, 11.9% and 2.7% of their loadings, respectively,were contributed by pollution inputs. Element exports mainly occurred in the summer(44.4%–57.4%) in the lower part of the Changjiang River. A general relationship between sediment retention and element content suggests a positive feedback mechanism for the decreased number of particles, in which element riverine loadings are reduced due to the enhanced trapping effect by the Three Gorges Dam(TGD). Compared to those in 1980,current element shares of the Changjiang River compared to the global budget have declined due to the construction of the TGD. | Hao Wang Xiangbin Ran Jingxi Li Jun Liu Wentao Wu Menglu Li Jiaye Zang | 2019 | Journal of Environmental Sciences2019，31，9： | 6 |

| 19 | Hierarchical porous cellulose/lanthanide hybrid materials as luminescent sensor显示文摘Photoluminescent hybrid materials containing carboxymethyl cellulose and lanthanide ions(Eu3+, Tb3+)were prepared by a facile method under ambient conditions. Lanthanide ions were covalently grafted to the cellulose framework through coordination with the carboxylic groups of the cellulose. Hybrid materials were fabricated as hydrogel and aerogel. As shown by SEM and pore parameters, aerogel materials which were obtained by supercritical CO_2 drying show hierarchical porous structure. The photoluminescence spectrum of the hybrid materials shows the characteristic red emission of Eu3+ ion and green emission of Tb^(3+). Further luminescent investigations reveal that these hybrid materials can detect Fe^(3+) with relative selectivity and high sensitivity, which suggests that the hybrid materials could be a promising luminescent probe for selectively sensing Fe^(3+) ion. | Wentao Fan Jiaojiao Du Junfeng Kou Zeyu Zhang Fengyi Liu | 2018 | Journal of Rare Earths2018，36，10： | 5 |
