| 1 | Saturation attack based route planning and threat avoidance algorithm for cruise missiles显示文摘According to the characteristic of cruise missiles,navigation point setting is simplified,and the principle of route planning for saturation attack and a concept of reference route are put forward.With the help of the shortest-tangent idea in route-planning and the algorithm of back reasoning from targets,a reference route algorithm is built on the shortest range and threat avoidance.Then a route-flight-time algorithm is built on navigation points.Based on the conditions of multi-direction saturation attack,a route planning algorithm of multi-direction saturation attack is built on reference route,route-flight-time,and impact azimuth.Simulation results show that the algorithm can realize missiles fired in a salvo launch reaching the target simultaneously from different directions while avoiding threat. | Guanghui Wang Xuefeng Sun Liping Zhang Chao Lv | 2011 | Journal of Systems Engineering and Electronics2011,22,6: | 11 |
| 2 | Effect of groundwater depth on riparian plant diversity along riverside-desert gradients in the Tarim River显示文摘Aims Riparian plant diversity is sensitive to changes in groundwater in arid regions.However,little is known about how plant diversity responds to changes in environment along riverside-desert gradi-ents in riparian ecosystem.Our objectives were to(i)identify ri-parian plant diversity along riverside-desert gradients in Tarim desert riparian forests,(ii)analyze the impact of environment variables on plant diversity,(iii)determine the optimum groundwater depth for different plant life-forms.Methods Six transects 90 quadrats(with each size 100 m×100 m)distributed vertically to river bed along riverside-desert gradients~30 km in length were surveyed.At each quadrat,the morphological features of riparian plant communities were measured,and the groundwater depth,soil water,soil salinity,soil nutrient were also monitored at same sites.Important Finding Three distinct vegetation communities were identified based on cover and richness in the tree,shrub and herb layers:the riparian zone,the transitional zone and the desert margin zone.Twelve spe-cies were indicators of the three vegetation communities.Riparian plant diversity was influenced by groundwater depth,distance from river,soil moisture content,soil salinity and soil nutrient by redundancy analysis.In response to groundwater depth,the op-timal groundwater depths for species diversity,evenness and shrub cover were 2.8,2.7 and 3.7 m,respectively.Therefore,maintaining high plant diversity requires managers to ensure stable groundwater depth for different plant life-forms rather than for some of them. | Yong Zeng Chengyi Zhao Jun Li Yan Li Guanghui Lv Tong Liu | 2019 | Journal of Plant Ecology2019,12,3: | 7 |
| 3 | Carbon uptake and change in net primary productivity of oasis-desert ecosystem in arid western China with remote sensing technique显示文摘Arid and semi-arid ecosystems exhibit a spatially complex biogeophysical structure. According to arid western special climate-vegetation characters, the fractional cover of photosynthetic vegetation (PV), non-photosynthetic vegetation (NPV), bare soil and water are unmixed, using the remote sensing spectral mixture analysis. We try the method to unmix the canopy funation structure of arid land cover in order to avoid the differentiation of regional vegetation system and the disturbance of environmental background. We developed a modified production efficiency model NPP-PEM appropriate for the arid area at regional scale based on the concept of radiation use efficiency. This model refer to the GLO-PEM and CASA model was driven with remotely sensed observations, and calculates not just the conversion efficiency of absorbed photosynthetically active radiation but also the carbon fluxes that determine net primary productivity (NPP). We apply and validate the model in the Kaxger and Yarkant river basins in arid western China. The NPP of the study area in 1992 and 1998 was estimated based on the NPP-PEM model. The results show that the improved PEM model, considering the photosynthetical activation of heterogeneous functional vegetation, is in good agreement with field measurements and the existing literature. An accurate agreement (R2 = 0.85, P<0.001) between the estimates and the ground-based measurement was obtained. The spatial distribution of mountain-oasis-desert ecosystem shows an obvious heterogeneous carbon uptake. The results are applicable to arid ecosystem studies ranging from characterizing carbon cycle, carbon flux over arid areas to monitoring change in mountain-oasis-desert productivity, stress and management. | ZHANG Jie PAN Xiaoling GAO Zhiqiang SHI Qingdong LV Guanghui | 2006 | Journal of Geographical Sciences2006,16,3: | 4 |
| 4 | Influence of soil microorganisms and physicochemical properties on plant diversity in an arid desert of Western China显示文摘Soil microorganisms and physicochemical properties are considered the two most influencing factors for maintaining plant diversity.However,the operational mechanisms and which factor is the most influential manipulator remain poorly understood.In this study,we examine the collaborative influences of soil physicochemical properties(i.e.,soil water,soil organic matter(SOM),salinity,total phosphorus and nitrogen,pH,soil bulk density and fine root biomass)and soil microorganisms(fungi and bacteria)on plant diversity across two types of tree patches dominated by big and small trees(big trees:height≥7 m and DBH≥60 cm;small trees:height≤4.5 m and DBH≤20 cm)in an arid desert region.Tree patch is consists of a single tree or group of trees and their accompanying shrubs and herbs.It was hypothesized that soil physicochemical properties and microorganisms affect plant diversity but their influence differ.The results show that plant and soil microbial diversity increased with increasing distances from big trees.SOM,salinity,fine root biomass,soil water,total phosphorus and total nitrogen contents decreased with increasing distance from big trees,while pH and soil bulk density did not change.Plant and soil microbial diversity were higher in areas close to big trees compared with small trees,whereas soil physicochemical properties were opposite.The average contribution of soil physicochemical properties(12.2%-13.5%)to plant diversity was higher than microbial diversity(4.8%-6.7%).Salinity had the largest negative affect on plant diversity(24.7%-27.4%).This study suggests that soil fungi constrain plant diversity while bacteria improve it in tree patches.Soil physicochemical properties are the most important factor modulating plant diversity in arid desert tree patches. | Xiaodong Yang Yanxin Long Binoy Sarkar Yan Li Guanghui Lv Arshad Ali Jianjun Yang Yue-E.Cao | 2021 | Journal of Forestry Research2021,32,6: | 2 |

| 7 | Age and geochemistry of Early Ordovician A-type granites in the Northeastern Songnen Block,NE China显示文摘Early Ordovician A-type granites in the northeastern(NE) Songnen Block NE China were studied to better understand the geodynamic settings in this region.This research presents new zircon U–Pb ages and wholerock geochemical data for the Early Ordovician granites in the NE Songnen Block. Zircon U–Pb dating indicates that the granite in the Cuibei, Hongxing, and Meixi areas in the NE Songnen Block formed in the Early Ordovician with ages of 471–479 Ma. The granites show geochemical characteristics of high SiO2 and K2 O compositions and low FeOT, MgO, CaO, and P2 O5 compositions. They belong to a high K calc-alkaline series and display a weak peraluminous featurPe with A/CNK values of 0.98–1.14. The rocks have aREE composition of 249.98–423.94 ppm,and are enriched in LREE with(La/Yb)Nvalues of2.87–9.87, and display obvious Eu anomalies(d Eu =0.01–0.29). Trace elements of the studied granites are characterized by enrichment in Rb, Th, U, Pb, Hf, and Sm,and depletion of Ba, Nb, Ta, and Sr. They display geochemical features of high Zr +Y + Nb+Ce values(324–795 ppm) and Ga/Al ratios consistent with A-type granites. Based on particular geochemical features, such as high Rb/Nb(7.98–24.19) and Y/Nb(1.07–3.43), the studied A-type granites can be further classified as an A2-type subgroup. This research indicates that the Early Ordovician A-type granites were formed by the partial melting of ancient crust in an extensional setting. Lower Sr/Y and(Ho/Yb)Nratios indicate that plagioclase and amphibole are residual in the source, and garnet is absent, implying that the magma was generated at low levels of pressure. By contrast, the contemporaneous granites in the SE Xing'an Block suggest a subduction-related tectonic setting, and its adakitic property indicates a thickened continental crust.We suggest that the Paleo-Asian Ocean plate between the Xing'an and Songnen blocks subducted northward during the Early Ordovician. Meanwhile, the NE Songnen Block was exposed to a passive continental margin tectonic setting. | Changzhou Deng Deyou Sun Guangyi Sun Changlu Lv Zhen Qin Xianquan Ping Guanghui Li | 2018 | Acta Geochimica2018,37,6: | 1 |
| 8 | Cooperative NHC/Photoredox Catalysis:Three-Component Reaction of Aroyl Fluorides,Styrenes and Oxalates显示文摘Cooperative NHC/photoredox catalysis has emerged as an important research field in recent years.Herein,this article describes the use of cesium salt derivatives of tert-alcohols as alkyl radical precursors in a three-component reaction with styrene and aromatic acyl fluorides to synthesizeα-arylalkyl aryl ketones.The aroyl fluoride reacts with the NHC catalyst,leading to the formation of an acyl azolium ion.This acyl azolium ion can then be reduced by the photoredox catalyst,generating the corresponding ketyl radical anion.The C-radical generated from oxalate oxidation undergoes an addition reaction with the styrene derivative,followed by cross-coupling of the addition radical with the ketone radical,which is fragmented by NHC to give the target ketone. | Zheng Lin Guanghui Lv Jianghong Liu Jiangyan Tang Binsong Mu Jian Chen Tianle Huang Zhongzhen Yang Yong Wu | 2024 | Chinese Journal of Chemistry2024,42,5: | 0 |

| 10 | 无水乙醇在颅内巨大高血运脑膜瘤中的应用(英文)显示文摘Objective:We evaluated the microsurgical effects of intratumoral injection ethanol into intracranial tumors,in particular,those with highly vascularized large meningiomas. Methods: Twelve patients presented with large meningioma,anhydrous ethanol was intraoperatively injected at an average volume of 15.4 mL followed by microscopic tumor resection. Results: Tumors in the injected sites became pallor to various extent and sclerous,leading to significantly decreased hemorrhage on the surface and cut. The average intraoperative hemorrhage was 88 mL. Complete tumor resection was achieved in 11 out of 12 patients; however,only 1 patient had 91.6% of the tumor resected. None of these patients had any postoperative complications. Conclusion: Intratumoral injection of anhydrous ethanol is a safe,convenient,and effective approach to diminish intraoperative bleeding for highly vascularized large meningiomas. | Guanghui Wang Jiman Li Hong Zhang Yuping Wu Yangcheng Lv Jiang Zhu | 2010 | The Chinese-German Journal of Clinical Oncology2010,9,6: | 0 |
| 11 | Paternally imprinted LATE-FLOWERING2 transcription factor contributes to paternal-excess interploidy hybridization barriers in wheat∞显示文摘Interploidy hybridization between hexaploid and tetraploid genotypes occurred repeatedly during genomic introgression events throughout wheat evolution,and is commonly employed in wheat breeding programs.Hexaploid wheat usually serves as maternal parent because the reciprocal cross generates progeny with severe defects and poor seed germination,but the underlying mechanism is poorly understood.Here,we performed detailed analysis of phenotypic variation in endosperm between two interploidy reciprocal crosses arising from tetraploid(Triticum durum,AABB)and hexaploid wheat(Triticum aestivum,AABBDD).In the paternal‐versus the maternal‐excess cross,the timing of endosperm cellularization was delayed and starch granule accumulation in the endosperm was repressed,causing reduced germination percentage.The expression profiles of genes involved in nutrient metabolism differed strongly between these endosperm types.Furthermore,expression patterns of parental alleles were dramatically disturbed in interploidy versus intraploidy crosses,leading to increased number of imprinted genes.The endosperm‐specific TaLFL2 showed a paternally imprinted expression pattern in interploidy crosses partially due to allele‐specific DNA methylation.Paternal TaLFL2 binds to and represses a nutrient accumulation regulator TaNAC019,leading to reduced storage protein and starch accumulation during endosperm development in paternal‐excess cross,as confirmed by interploidy crosses between tetraploid wild‐type and clustered regularly interspaced palindromic repeats(CRISPR)–CRISPR‐associated protein 9 generated hexaploid mutants.These findings reveal a contribution of genomic imprinting to paternal‐excess interploidy hybridization barriers during wheat evolution history and explains why experienced breeders preferentially exploit maternal‐excess interploidy crosses in wheat breeding programs. | Guanghui Yang Man Feng Kuohai Yu Guangxian Cui Yan Zhou Lv Sun Lulu Gao Yumei Zhang Huiru Peng Yingyin Yao Zhaorong Hu Vincenzo Rossi Ive De Smet Zhongfu Ni Qixin Sun Mingming Xin | 2023 | Journal of Integrative Plant Biology2023,65,12: | 0 |
| 12 | Controlled moderative sulfidation-fabricated hierarchical heterogeneous nickel sulfides-based electrocatalyst with tripartite Mo doping for efficient oxygen evolution显示文摘An electrocatalyst with heterogeneous nanostructure, especially the hierarchical one, generally shows a more competitive activity than that of its single-component counterparts for oxygen evolution reaction(OER), due to the synergistically enhanced kinetics on enriched active sites and reconfigured electronic band structure. Here this work introduces hierarchical heterostructures into a NiMo@NiS/MoS_(2)@Ni_(2)S_(2)/MoO_(x)(NiMoS) composite by one-pot controlled moderative sulfidation. The optimal solvent composition and addition of NaOH enable NiMoS to own loose and porous structures, smaller nanoparticle sizes, optimal phase composition and chemical states of elements, improving the OER activity of NiMoS. To achieve current densities of 50 and 100 mA cm^(-1), small overpotentials of 275 and 306 mV are required respectively, together with a minor Tafel slope of 58 mV dec^(-1), which outperforms most reported sulfide catalysts and IrO_(2). The synergistic effects in the hierarchical heterostructures expose more active sites,adjust the electronic band structure, and enable the fast charge transfer kinetics, which construct an optimized local coordination environment for high OER electrocatalytic activity. Furthermore, the hierarchical heterostructures suppress the distinct lowering of electrical conductivity and collapse of pristine structures resulted from the metal oxidation and synchronous S leaching during OER, yielding competitive catalytic stability. | Xing Yu Qingyun Lv Lulu She Long Hou Yves Fautrelle Zhongming Ren Guanghui Cao Xionggang Lu Xi Li | 2022 | Journal of Energy Chemistry2022,31,5: | 0 |
| 13 | Identifying Vital Nodes in Social Networks Using an Evidential Methodology Combining with High-Order Analysis显示文摘Identifying vital nodes is a basic problem in social network research.The existing theoretical framework mainly focuses on the lowerorder structure of node-based and edge-based relations and often ignores important factors such as interactivity and transitivity between multiple nodes.To identify the vital nodes more accurately,a high-order structure,named as the motif,is introduced in this paper as the basic unit to evaluate the similarity among the node in the complex network.It proposes a notion of high-order degree of nodes in complex network and fused the effect of the high-order structure and the lower-order structure of nodes,using evidence theory to determine the vital nodes more efficiently and accurately.The algorithm was evaluated from the function of network structure.And the SIR model was adopted to examine the spreading influence of the nodes ranked.The results of experiments in different datasets demonstrate that the algorithm designed can identify vital nodes in the social network accurately. | Meng Zhang Guanghui Yan Yishu Wang Ye Lv | 2020 | 国际计算机前沿大会会议论文集2020,,1: | 0 |
| 14 | Genome-wide identification and expression analysis of the GhIQD gene family in upland cotton(Gossypium hirsutum L.)显示文摘Background:Calmodulin(CaM)is one of the most important Ca^(2+)signaling receptors because it regulates diverse physiological and biochemical reactions in plants.CaM functions by interacting with CaM-binding proteins(CaMBPs)to modulate Ca^(2+)signaling.IQ domain(IQD)proteins are plant-specific CaMBPs that bind to CaM by their specific CaM binding sites.Results:In this study,we identified 102 GhIQD genes in the Gossypium hirsutum L.genome.The GhIQD gene family was classified into four clusters(Ⅰ,Ⅱ,Ⅲ,andⅣ),and we then mapped the GhIQD genes to the G.hirsutum L.chromosomes.Moreover,we found that 100 of the 102 GhIQD genes resulted from segmental duplication events,indicating that segmental duplication is the main force driving GhIQD gene expansion.Gene expression pattern analysis showed that a total of 89 GhIQD genes expressed in the elongation stage and second cell wall biosynthesis stage of the fiber cells,suggesting that GhIQD genes may contribute to fiber cell development in cotton.In addition,we found that 20 selected GhIQD genes were highly expressed in various tissues.Exogenous application of MeJA significantly enhanced the expression levels of GhIQD genes.Conclusions:Our study shows that GhIQD genes are involved in fiber cell development in cotton and are also widely induced by MeJA.Thw results provide bases to systematically characterize the evolution and biological functions of GhIQD genes,as well as clues to breed better cotton varieties in the future. | DOU Lingling LV Limin KANG Yangyang TIAN Ruijie HUANG Deqing LI Jiayin LI Siyi LIU Fengping CAO Lingyan JIN Yuhua LIU Yang LI Huaizhu WANG Wenbo PANG Chaoyou SHANG Haihong ZOU Changsong SONG Guoli XIAO Guanghui | 2021 | Journal of Cotton Research2021,4,1: | 0 |
| 15 | Recent advances in platelet engineering for anti-cancer therapies显示文摘Platelets contribute a major role in hemostasis by clumping and coagulation at the site of blood vessel injuries.In light of recent findings of a close relationship between platelets and immunological response,as well as interactions between platelets and cancer cells,novel engineering strategies have emerged for the integration of platelets or platelet membrane(PM)with anti-cancer therapeutics.In this review,we discuss several recent innovations that use platelets or their membranes to circumvent host immune responses and target tumor cells with high specificity to deliver a range of pharmacological,photothermal,or immunologic agents for eradication of recalcitrant tumor cells.More specifically,we compare the relative advantages of using whole platelets versus single or hybrid PM to coat nanoparticle cargoes.These cargoes range from well-established anti-tumor apoptosis-inducing agents,to relatively new photothermal agents that can induce a feedback cascade in which they induce vascular damage to the tumor which recruits more platelet-or membrane-encapsulated agents to induce further damage.We also discuss the use of engineered platelets to produce programmed cell death-inducing platelet derived microparticles.This review provides an overview and future directions for this promising platelet-based biomimetic approach to anti-cancer therapy. | Yanlin Lv Wei Wei Guanghui Ma | 2022 | Particuology2022,20,5: | 0 |
| 16 | 带蒂额肌帽状腱膜裂层颅骨瓣修复前颅底(英文)显示文摘Objective:The aim of our study was to reconstruct soft and hard tissue perforating defects of the anterior skull base in a 1-stage surgical procedure with a combined craniofacial approach. Methods:Soft and hard tissue defects of the anterior skull base were successfully reconstructed in 43 patients during a 1-stage surgery through the use of frontalis muscle galea aponeurotica skull flaps with 1 or 2 vascularized pedicles. The skull flap areas were up approximately 7cm × 14cm. Results:Intracranial infection and cerebrospinal fluid leakage were not observed in the 43 patients, and all incisions healed. Of 33 malignant tumor patients, 25 patients received follow-up examinations for longer than 2 years, and 18 patients survived for 2 years. Conclusion:Frontalis muscle galea aponeurotica skull pedicle flaps provided a constant blood supply and resulted in soft and thin tissue. The pedicle flaps, together with the external cranial bone plate, strengthened the support, but still allowed for bending and shaping. In addition, the flap harvesting approach was consistent with surgery approach, without aesthetic compromises. | Kun Liu Guanghui Wang Hong Zhang Yuping Wu Yangcheng Lv Jingsong Liu Jieke Ma Cheng Li Jiang Zhu | 2013 | The Chinese-German Journal of Clinical Oncology2013,12,6: | 0 |
