1On adjacent-vertex-distinguishing total coloring of graphs显示文摘In this paper, we present a new concept of the adjacent-vertex-distinguishing total coloring of graphs (briefly, AVDTC of graphs) and, meanwhile, have obtained the adjacent-vertex-distinguishing total chromatic number of some graphs such as cycle, complete graph, complete bipartite graph, fan, wheel and tree.ZHANG Zhongfu, CHEN Xiang’en, LI Jingwen, YAO Bing, LU Xinzhong & WANG Jianfang College of Mathematics and Information Science, Northwest Normal University, Lanzhou 730070, China Department of Computer, Lanzhou Normal College, Lanzhou 730070, China Institute of Applied Mathematics, Lanzhou Jiaotong University, Lanzhou 730070, China College of Information and Electrical Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China Institute of Applied Mathematics, Chinese Academy of Sciences, Beijing 100080, China 2005Science China Mathematics2005,48,3:173
2On the adjacent-vertex-strongly-distinguishing total coloring of graphs显示文摘For any vertex u∈V(G), let TN(U)={u}∪{uv|uv∈E(G), v∈v(G)}∪{v∈v(G)|uv∈E(G)}and let f be a total k-coloring of G. The total-color neighbor of a vertex u of G is the color set Cf(u)={f(x)|x∈TN(U)}. For any two adjacent vertices x and y of V(G)such that Cf(x)≠Cf(y), we refer to f as a k-avsdt-coloring of G('avsdt'is the abbreviation of'adjacent-vertex-strongly- distinguishing total'). The avsdt-coloring number of G, denoted by Xast(G), is the minimal number of colors required for a avsdt-coloring of G. In this paper, the avsdt-coloring numbers on some familiar graphs are studied, such as paths, cycles, complete graphs, complete bipartite graphs and so on. We proveΔ(G)+1≤Xast(G)≤Δ(G)+2 for any tree or unique cycle graph G.ZHANG ZhongFu CHENG Hui YAO Bing LI JingWen CHEN XiangEn XU BaoGen 2008Science China Mathematics2008,51,3:74
3D(β)-vertex-distinguishing total coloring of graphs显示文摘A new concept of the D(β)-vertex-distinguishing total coloring of graphs, i.e., the proper total coloring such that any two vertices whose distance is not larger than β have different color sets, where the color set of a vertex is the set composed of all colors of the vertex and the edges incident to it, is proposed in this paper. The D(2)-vertex-distinguishing total colorings of some special graphs are discussed, meanwhile, a conjecture and an open problem are presented.ZHANG Zhongfu,LI Jingwen,CHEN Xiang’en,YAO Bing, WANG Wenjie & QIU Pengxiang Institute of Applied Mathematic, Lanzhou Jiaotong University, Lanzhou 730070, China College of Mathematics and Information Science, Northwest Normal University, Lanzhou 730070, China College of Information and Electrical Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China 2006Science China Mathematics2006,49,10:54
4SHRIMP zircon U-Pb dating for volcanic rocks of the Dasi Formation in southeast Hubei Province,middle-lower reaches of the Yangtze River and its implications显示文摘The Jinniu Basin in southeast Hubei,located at the westernmost part of middle-lower val-ley of the Yangtze River,is one of the important vol-canic basins in East China. Volcanic rocks in the Jin-niu Basin are distributed mainly in the Majiashan Formation,the Lingxiang Formation and the Dasi Formation,consisting of rhyolite,basalt and basaltic andesite,(trachy)-basalt and basaltic trachy-andesite and (trachy)-andesite and (trachy)-dacite and rhyolite respectively,in which the Dasi volcanism is volumet-rically dominant and widespread. The Dasi volcanic rocks were selected for SHRIMP zircon U-Pb dating to confirm the timing of volcanism. The results indi-cate that there exist a large amount of magmatic zir-cons characterized by high U and Th contents in the volcanic rocks. The concordia ages for 13 points are 128 ± 1Ma (MSWD = 3.0). On account of the shape of zircons and Th/U ratios,this age is considered to represent the crystallization time of the Dasi volcan-ism. The volcanic rocks in the Dasi,Majiashan and Lingxiang Formations share similar trace elementand REE partition patterns as well as Sr-Nd isotopic compositions. In combination with the regional geol-ogy,it is proposed that the southeast Hubei volcanic rocks were formed mainly during the Early Creta-ceous,just like other volcanic basins in middle-lower Yangtze valley. A lithospheric extension is also sug-gested for tectonic regime in this region in the Cre-taceous Period.XIE Guiqing MAO Jingwen LI Ruiling ZHOU Shaodong YE Huishou YAN Quanren ZHANG Zusong 2006Chinese Science Bulletin2006,51,24:38
5Cas9-NG Greatly Expands the Targeting Scope of the Genome-Editing Toolkit by Recognizing NG and Other Atypical PAMs in Rice显示文摘CRISPR technologies enabling precise genome manipulation are valuable for gene function studies and molecular crop breeding. However, the requirement of a protospacer adjacent motif (PAM)y such as NGG and TTN, for Cas protein recognition restricts the selection of targetable genomic loci in practical applications of CRISPR technologies. Recently Cas9-NG, which recognizes a minimal NG PAM, was reported to expand the targeting space of genome editing in human cells, but it remains unclear whether this Cas9 variant can be used in plants. In this study, we evaluated the nuclease activity of Cas9-NG toward various NGN PAMs by targeting endogenous genes in transgenic rice. We found that Cas9-NG edits all NGG, NGA, NGT, and NGC sites with impaired activity, while the gene-edited plants were dominated by monoallelic mutations. Cas9-NG-engineered base editors were then developed and used to generate O s B Z R I gainof- function plants that can not be created by other available Cas9-engineered base editors. Moreover, we showed that a Cas9-NG-based transcriptional activator efficiently upregulated the expression of endogenous target genes in rice. In addition, we discovered that Cas9-NG recognizes NAC, NTG, NTT, and NCG apart from NG PAM. Together, these findings demonstrate that Cas9-NG can greatly expand the targeting scope of genome-editing tools, showing great potential for targeted genome editing, base editing, and genome regulation in plants.Bin Ren Lang Liu Shaofang Li Yongjie Kuang Jingwen Wang Dawei Zhang Xueping Zhou Honghui Lin Huanbin Zhou 2019Molecular Plant2019,12,7:18
6Mesozoic Large-scale Mineralization and Multiple Lithospheric Extensions in South China显示文摘华南是最重要的 polymetallic (钨,锡,铋,铜,银,锑,水银,稀罕金属,重稀土元素元素,黄金和铅锌) 在中国的省。这篇论文在华南描述中生代 large-scalemineralization 的基本特征。大规模矿化作用主要发生在三个 intervals:170-150 妈, 140-126 妈和 110-80 妈。在这些之中,第一个阶段被铜,铅锌和钨矿化作用和第三个阶段主要标记被锡,黄金,银和铀矿化作用主要描绘。钨和听矿化作用主要描绘的 140-126 妈的阶段是从第一的过渡间隔到第三个阶段。考虑到地区性的构造进化的当前的研究结果,在三个阶段的 large-scalemineralization 与有关,这被建议在华南块和北方中国块之间碰撞以后,到 E-Wdirection 的从 N-S 的构造政体的主要压力地的转移,并且球的延期由 Paleo-Pacificplate 的 subductlon 引起了的多重背弧石版印刷。MAO Jingwen XIE Guiqing LI Xiaofeng ZHANG Changqing WANG Yitian 2006Acta Geologica Sinica(English Edition)2006,80,3:13
7Design, synthesis and biological evaluation of chalcone analogues with novel dual antioxidant mechanisms as potential anti-ischemic stroke agents显示文摘Scavenging reactive oxygen species(ROS) by antioxidants is the important therapy to cerebral ischemia-reperfusion injury(CIRI) in stroke. The antioxidant with novel dual-antioxidant mechanism of directly scavenging ROS and indirectly through antioxidant pathway activation may be a promising CIRI therapeutic strategy. In our study, a series of chalcone analogues were designed and synthesized, and multiple potential chalcone analogues with dual antioxidant mechanisms were screened. Among these compounds, the most active 33 not only conferred cytoprotection of H2 O2-induced oxidative damage in PC12 cells through scavenging free radicals directly and activating NRF2/ARE antioxidant pathway at the same time, but also played an important role against ischemia/reperfusion-related brain injury in animals. More importantly, in comparison with mono-antioxidant mechanism compounds, 33 exhibited higher cytoprotective and neuroprotective potential in vitro and in vivo. Overall, our findings showed compound 33 couldemerge as a promising anti-ischemic stroke drug candidate and provided novel dual-antioxidant mechanism strategies and concepts for oxidative stress-related diseases treatment.Jiabing Wang Lili Huang Chanchan Cheng Ge Li Jingwen Xie Mengya Shen Qian Chen Wulan Li Wenfei He Peihong Qiu Jianzhang Wu 2019Acta Pharmaceutica Sinica B2019,9,2:13
8Jurassic Intra-plate Basaltic Magmatism in Southeast China:Evidence from Geological and Geochemical Characteristics of the Chebu Gabbroite in Southern Jiangxi Province显示文摘Geochemical and isotopic investigations have been carried out on the Chebu gabbroite in southern Jiangxi Province, southeast China and these results are compared with gabbro bodies along the coast of Fujian Province in order to understand their magma sources and tectonic implications. The Chebu intrusion formed at the beginning of the Middle Jurassic (172±4.3 Ma). These rocks are Ti-rich and Al-poor in major elements, characterized by strong enrichment in large-ion lithophile elements (LILE) and moderate enrichment in high field strength elements (HFSE) and light rare-earth elements (LREE), without pronounced Nb or Ta anomalies. Age-correlated Sr-Nd isotope ratios show moderately high ranges of (87Sr/86Sr)i from 0.7065 to 0.7086 and 0.5124 to 0.5125 of (143Nd/144Nd)i. The geochemical characteristics of the Chebu gabbroite suggest that it is notably different from island-arc basalt and similar to intra-plate basaltic rocks. By combining interpretations of its geological and geochemical characteristics and the regional geological development history, the Chebu gabbroitic intrusion is thought to be the product of asthenosphere upwelling and rapid lithosphere extension during a transition of tectonic systems in southeast China. The tectonic environment and source characteristics of the intrusion are different from Cretaceous gabbro bodies along the coast of Fujian Province, The former formed in a tectonic environment of rapid intra-plate lithospheric extension and the source characteristics were of a weakly enriched primitive mantle, whereas the latter originated mainly in a volcanic-magmatic arc extensional tectonic environment and the nature of the source was an enriched mantle with more subduct subducted components.XIE Guiqing MAO Jingwen HU Ruizhong LI Ruiling JIANG Guohao CAO Jinjian ZHAO Junhong 2005Acta Geologica Sinica(English Edition)2005,79,5:10
9A comparative study on source apportionment of polycyclic aromatic hydrocarbons in sediments of the Daliao River,China:Positive matrix factorization and factor analysis with non-negative constraints显示文摘Two receptor models,positive matrix factorization (PMF) and factor analysis with non-negative constraints (FA-NNC),were applied for source apportionment of polycyclic aromatic hydrocarbons (PAHs) in sediments of the Daliao River,China.The source profiles and source contributions derived from the two receptor models were comparable.For PMF,PAHs mainly came from coal combustion (43.3%),followed by biomass burning (24.3%),traffic emissions (16.7%) and coke oven (15.7%).As for FA-NNC,coal combustion (50.4%) was dominant,followed by biomass burning (21.9%),traffic emission (15.7%) and coke oven (12.0%).The source apportionment results are consistent with the results from the specific PAH diagnostic ratios and emission inventory analysis.In addition,the source apportionment results are consistent with the structure of energy material usage in Liaoning Province of China.LIU ChunHui TIAN FuLin CHEN JingWen LI XueHua QIAO XianLiang 2010Chinese Science Bulletin2010,55,10:10
10Simulation 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
11Breaking 12% efficiency in flexible organic solar cells by using a composite electrode显示文摘The performance of flexible organic solar cells(OSCs)significantly relies on the quality of transparent flexible electrode.Here,we used silver nanowires(AgNWs)with various weight ratios to dope high-conductive poly(3,4-ethylenedioxythiophene):polystyrene sulfonate(PH1000)to optimize the optical and electronic properties of PH1000 film.A high-quality flexible composite electrode PET/Ag-mesh/PH1000:AgNWs-20 with smooth surface,a low sheet resistance of 6Ω/sq and a high transmittance of 86%at 550-nm wavelength was obtained by doping 20 wt%AgNWs to PH1000(PH1000:AgNWs-20).The flexible OSCs based on the PET/Ag-mesh/PH1000:AgNWs-20 electrode delivered a power conversion efficiency(PCE)of12.07%with an open circuit voltage(Voc)of 0.826 V,a short-circuit current density(Jsc)of 20.90 m A/cm2and a fill factor(FF)of69.87%,which is the highest reported PCE for the flexible indium-tin oxide(ITO)-free OSCs.This work demonstrated that the flexible composite electrodes of PET/Ag-mesh/PH1000:AgNWs are promising alternatives for the conventional PET/ITO electrode,and open a new avenue for developing high-performance flexible transparent electrode for optoelectronic devices.Guang Zeng Jingwen Zhang Xiaobin Chen Hongwei Gu Yaowen Li Yongfang Li 2019Science China Chemistry2019,62,7:9

13Progress and perspectives of quantitative structure-activity relationships used for ecological risk assessment of toxic organic compounds显示文摘Structure-activity relationship (SAR) and quantitative structure-activity relationship (QSAR), collec- tively referred to as (Q)SARs, play an important role in ecological risk assessment (ERA) of organic chemicals. (Q)SARs can fill the data gap for physical-chemical, environmental behavioral and ecotoxicological parameters of organic compounds; they can decrease experimental expenses and reduce the extent of experimental testing (especially animal testing); they can also be used to assess the uncertainty of the experimental data. With the development for several decades, (Q)SARs in envi- ronmental sciences show three features: application orientation, multidisciplinary integration, and in- telligence. Progress of (Q)SAR technology for ERA of toxic organic compounds, including endpoint selection and mathematic methods for establishing simple, transparent, easily interpretable and portable (Q)SAR models, is reviewed. The recent development on defining application domains and diagnosing outliers is summarized. Model characterization with respect to goodness-of-fit, stability and predictive power is specially presented. The purpose of the review is to promote the development of (Q)SARs orientated to ERA of organic chemicals.CHEN JingWen LI XueHua YU HaiYing 2008Science China Chemistry2008,51,7:9
14Integrated transcriptomic and metabolomic analyses of a wax deficient citrus mutant exhibiting jasmonic acid-mediated defense against fungal pathogens显示文摘Naturally,resistant crop germplasms are important resources for managing the issues of agricultural product safety and environment deterioration.We found a spontaneous mutant of‘Newhall’navel orange(Citrus sinensis Osbeck)(MT)with broad-spectrum protections against fungal pathogens in the orchard,postharvest-storage,and artificial inoculation conditions.To understand the defense mechanism of MT fruit,we constructed a genome-scale metabolic network that integrated metabolome and transcriptome datasets.The coordinated transcriptomic and metabolic data were enriched in two sub-networks,showing the decrease in very long chain fatty acid(by 41.53%)and cuticular wax synthesis(by 81.34%),and increase in the synthesis of jasmonic acid(JA)(by 95.23%)and JA-induced metabolites such as 5-dimethylnobietin(by 28.37%)in MT.Furthermore,cytological and biochemical analyses confirmed that the response to fungal infection in MT was independent of wax deficiency and was correlated with the levels of jasmonates,and the expression of plant defensin gene PDF1.2.Results of exogenous application of MeJA and JA inhibitors such as propyl gallate proved that JA-mediated defense contributes to the strong tolerance against pathogens in MT.Our results indicated that jasmonate biosynthesis and signaling are stimulated by the fatty acid redirection of MT,and participate in the tolerance of pathogenic fungi.Yizhong He Jingwen Han Runsheng Liu Yuduan Ding Jinqiu Wang Li Sun Xiaoming Yang Yunliu Zeng Weiwei Wen Juan Xu Hongming Zhang Xiang Yan Zhaoxing Chen Zuliang Gu Hong Chen Huanqing Tang Xiuxin Deng Yunjiang Cheng 2018Horticulture Research2018,5,1:8
15Integration of GPS and low cost INS for pedestrian navigation aided by building layout显示文摘In outdoor environments,GPS is often used for pedestrian navigation by utilizing its signals for position computation,but in indoor or semi-obstructed environments,GPS signals are often unavailable.Therefore,pedestrian navigation for these environments should be realized by the integration of GPS and inertial navigation system(INS).However,the lowcost INS could induce errors that may result in a large position drift.The problem can be minimized by mounting the sensors on the pedestrian's foot,using zero velocity update(ZUPT) method with the standard navigation algorithm to restrict the error growth.However,heading drift still remains despite using ZUPT measurements since the heading error is unobservable.Also,foot mounted INS suffers from the initialization ambiguity of position and heading from GPS.In this paper,a novel algorithm is developed to mitigate the heading drift problem when using ZUPT.The method uses building layout to aid the heading measurement in Kalman flter,and it could also be combined for the initialization.The algorithm has been investigated with real feld trials using the low cost Microstrain3DM-GX3-25 inertial sensor,a Leica GS10 GPS receiver and a uBlox EVK-6T GPS receiver.It could be concluded that the proposed method offers a signifcant improvement in position accuracy for the long period,allowing pedestrian navigation for nearly40 min with mean position error less than 2.8 m.This method also has a considerable effect on the accuracy of the initialization.Feng Wenquan Zhao Hongbo Zhao Qi Li Jingwen 2013Chinese Journal of Aeronautics2013,26,5:8
16Vertically Aligned Silicon Carbide Nanowires/Boron Nitride Cellulose Aerogel Networks Enhanced Thermal Conductivity and Electromagnetic Absorbing of Epoxy Composites显示文摘With the innovation of microelectronics technology, the heat dissipation problem inside the device will face a severe test. In this work, cellulose aerogel(CA) with highly enhanced thermal conductivity(TC) in vertical planes was successfully obtained by constructing a vertically aligned silicon carbide nanowires(SiC NWs)/boron nitride(BN) network via the ice template-assisted strategy. The unique network structure of SiC NWs connected to BN ensures that the TC of the composite in the vertical direction reaches 2.21 W m^(-1) K^(-1) at a low hybrid filler loading of 16.69 wt%, which was increased by 890% compared to pure epoxy(EP). In addition, relying on unique porous network structure of CA, EP-based composite also showed higher TC than other comparative samples in the horizontal direction. Meanwhile, the composite exhibits good electrically insulating with a volume electrical resistivity about 2.35 × 10^(11) Ω cm and displays excellent electromagnetic wave absorption performance with a minimum reflection loss of-21.5 dB and a wide effective absorption bandwidth(<-10 dB) from 8.8 to 11.6 GHz. Therefore, this work provides a new strategy for manufacturing polymer-based composites with excellent multifunctional performances in microelectronic packaging applications.Duo Pan Gui Yang Hala MAbo-Dief Jingwen Dong Fengmei Su Chuntai Liu Yifan Li Ben Bin Xu Vignesh Murugadoss Nithesh Naik Salah MEl-Bahy Zeinhom MEl-Bahy Minan Huang Zhanhu Guo 2022Nano-Micro Letters2022,14,7:7
17Mechanical Properties and Stress Strain Relationship Models for Bamboo Scrimber显示文摘In order to investigate the basic mechanical properties and stress strain relationship model for bamboo scrimber manufactured based on a new technique,a large quantities of experiments have been carried out.Based on the analysis of the test results,the following conclusions can be drawn.Two main typical failure modes were classified for bamboo scrimber specimens both under tension parallel to grain and tension perpendicular to grain.Brittle failure happened for all tensile tests.The slope values for the elastic stages have bigger discreteness compared with those for the specimens under tensile parallel to grain.The failure modes for bamboo scrimber specimens under compression parallel to grain could be divided into four.Only one main failure mode happened both for the bending specimens and the shear specimens.With the COV values of 28.64 and 25.72 respectively,the values for the strength and elastic modulus under tensile perpendicular to grain have the largest discreteness for bamboo scrimber.From the point of CHV values,the relationship among the mechanical parameters for bamboo scrimber were proposed based on the test results.Compared with other green building materials,bamboo scrimber manufactured based on a new technique has better mechanical performance and could be used in construction area.Three stress strain relationship models which are four-linear model,quadratic function model,and cubic function model were proposed for bamboo scrimber specimens manufactured based on a new technique.The latter two models gives better prediction for stress strain relationship in elastic plastic stage.Haitao Li Huizhong Zhang Zhenyu Qiu Jingwen Su Dongdong Wei Rodolfo Lorenzo Conggan Yuan Hongzheng Liu Chungui Zhou 2020Journal of Renewable Materials2020,8,1:7

19Correlation of Gut Microbiome Between ASD Children and Mothers and Potential Biomarkers for Risk Assessment显示文摘Variation of maternal gut microbiota may increase the risk of autism spectrum disorders(ASDs) in offspring. Animal studies have indicated that maternal gut microbiota is related to neurodevelopmental abnormalities in mouse offspring, while it is unclear whether there is a correlation between gut microbiota of ASD children and their mothers. We examined the relationships between gut microbiome profiles of ASD children and those of their mothers, and evaluated the clinical discriminatory power of discovered bacterial biomarkers. Gut microbiome was profiled and evaluated by 16S ribosomal RNA gene sequencing in stool samples of 59 mother–child pairs of ASD children and 30 matched mother–child pairs of healthy children. Significant differences were observed in the gut microbiome composition between ASD and healthy children in our Chinese cohort. Several unique bacterial biomarkers, such as Alcaligenaceae and Acinetobacter, were identified. Mothers of ASD children had more Proteobacteria, Alphaproteobacteria, Moraxellaceae, and Acinetobacter than mothers of healthy children. There was a clear correlation between gut microbiome profiles of children and their mothers; however, children with ASD still had unique bacterial biomarkers, such as Alcaligenaceae, Enterobacteriaceae, and Clostridium. Candidate biomarkers discovered in this study had remarkable discriminatory power. The identified patterns of mother–child gut microbiome profiles may be important for assessing risks during the early stage and planning of personalized treatment and prevention of ASD via microbiota modulation.Ning Li Junjie Yang Jiaming Zhang Cheng Liang Ying Wang Bin Chen Changying Zhao Jingwen Wang Guangye Zhang Dongmei Zhao Yi Liu Lehai Zhang Jun Yang Guimei Li Zhongtao Gai Lei Zhang Guoping Zhao 2019Genomics, Proteomics & Bioinformatics2019,17,1:6
