| 2 | Spatial patterns of ephemeral plants in Gurbantünggüt Desert显示文摘In the present research,the authors measured parameters of richness,cover and importance value of ephemeral and ephemeroid plants on south-north and east-west transects in the Gurbantünggüt Desert in early spring,and investigated and analyzed the microhabitats,such as terrain,geomorphology,soil physical-chemical properties and crusts. By comparison,the regional differences in the ephemeral distribution in the desert were revealed. The species of ephemeral plants in the south and center are the richest and those in the west are the poorest in the desert. The cover of ephemeral plants in the mid-south is higher than that in the north,and that in the mid-east is higher than that in the west. The response of ephemeral plants to the spatial variation of the desert habitat forms the population-habitat gradient of ephemeral plants. The characteristics are:(1) In the habitat with higher terrain,coarser textured soil with poorer sorting and correspondingly higher organic matter and lower alkali-saline contents,Carex physoides and Eremopyrum orientale are the dominant ephemeral plants;(2) In the dry habitat with lower terrain,looser textured soil,some organic matter,alkali-saline soil,and developed crust,the ephemeral plants Alyssum linifolium and Erodium oxyrrhynchum are of characteristic of drought and alkali-saline tolerance;(3) In the habitat with lower terrain,some water and more alkali-saline soil,the ephemeral plants Neotorularia torulosa and Hypecoum parviflorum being of alkali-saline tolerance are mainly developed. However,most ephemerals are distributed in a habitat order of higher terrain,some organic,and less alkali-saline soil on the above-mentioned ephemeral population-habitat gradient. The spatial gradient of variation in desert microhabitats is small,and as a whole,the physio-logical character of mesophytism is represented by the desert ephemerals. | QIAN YiBing WU ZhaoNing ZHANG LiYun ZHAO RuiFeng WANG XiaoYan LI YouMin | 2007 | Chinese Science Bulletin2007,52,22: | 16 |
| 3 | Accurate Evaluation of Free-form Surface Profile Error Based on Quasi Particle Swarm Optimization Algorithm and Surface Subdivision显示文摘Although significant progress has been made in precision machining of free-form surfaces recently, inspection of such surfaces remains a difficult problem. In order to solve the problem that no specific standards for the verification of free-form surface profile are available, the profile parameters of free-form surface are proposed by referring to ISO standards regarding form tolerances and considering its complexity and non-rotational symmetry. Non-uniform rational basis spline(NURBS) for describing free-form surface is formulated. Crucial issues in surface inspection and profile error verification are localization between the design coordinate system(DCS) and measurement coordinate system(MCS) for searching the closest points on the design model corresponding to measured points. A quasi particle swarm optimization(QPSO) is proposed to search the transformation parameters to implement localization between DCS and MCS. Surface subdivide method which does the searching in a recursively reduced range of the parameters u and v of the NURBS design model is developed to find the closest points. In order to verify the effectiveness of the proposed methods, the design model is generated by NURBS and the measurement data of simulation example are generated by transforming the design model to arbitrary position and orientation, and the parts are machined based on the design model and are measured on CMM. The profile errors of simulation example and actual parts are calculated by the proposed method. The results verify that the evaluation precision of freeform surface profile error by the proposed method is higher 10%-22% than that by CMM software. The proposed method deals with the hard problem that it has a lower precision in profile error evaluation of free-form surface. | WEN Xiulan ZHAO Yibing WANG Dongxia ZHU Xiaochun XUE Xiaoqiang | 2013 | Chinese Journal of Mechanical Engineering2013,26,2: | 13 |
| 4 | The Coix Genome Provides Insights into Panicoideae Evolution and Papery Hull Domestication显示文摘Coix is a grass crop domesticated as early as the Neolithic era.It is still widely cultivated for both highly nutritional food and medicinal use.However,the genetic study and breeding of this crop are hindered by the lack of a sequenced genome.Here,we report de novo sequencing and assembly of the 1619-Mb genome of Coix,and annotation of 75.39%repeats and 39629 protein-coding genes.Comparative genomics analysis showed that Coix is more closely related to sorghum than maize,but intriguingly only Coix and maize had a recent genome duplication event,which was not detected in sorghum.We further constructed a genetic map and mapped several important traits,especially the strength of hull.Selection of papery hull(thin:easy dehulling)from the stony hull(thick:difficult dehulling)in wild progenitors was a key step in Coix domestication.The papery hull makes seed easier to process and germinate.Anatomic and global transcriptome analysis revealed that the papery hull is a result of inhibition of cell division and wall biogenesis.We also successfully demonstrated that seed hull pressure resistance is controlled by two major quantitative trait loci(QTLs),which are associated with hull thickness and color,respectively.The two QTLs were further fine mapped within intervals of 250 kb and 146 kb,respectively.These resources provide a platform for evolutionary studies and will facilitate molecular breeding of this important crop. | Chao Guo Yanan Wang Aiguo Yang Jun He Chaowen Xiao Shanhua Lv Fengming Han Yibing Yuan Yuan Yuan Xiaolong Dong Juan Guo YawenYang-Hailan Liu Ningzhi Zuo Yaxi Hu Kangxu Zhao Zhengbo Jiang Xing Wang Tingting Jiang Yaou Sherf Moju Cao Yuan Wang Zhaobo Long Tingzhao Rong Luqi Huang Shufeng Zhou | 2020 | Molecular Plant2020,13,2: | 11 |

| 6 | Some projectively flat (α,β)-metrics显示文摘In this paper, we study a class of Finsler metrics in the form F = α + ∈β + 2k β2/α-k2β4/3α3 , where α= (√aijyiyj) is a Riemannian metric, β = biyi is a 1-form, and ∈ and k ≠ 0 are constants. We obtain a sufficient and necessary condition for F to be locally projectively flat and give the non-trivial special solutions. Moreover, it is proved that such projectively flat Finsler metrics with the constant flag curvature must be locally Minkowskian. | SHEN Yibing ZHAO Lili | 2006 | Science China Mathematics2006,49,6: | 7 |

| 9 | A facile and general approach for the synthesis of fluorescent silica nanoparticles doped with inert dyes显示文摘A general and facile approach was developed for the synthesis of almost monodisperse fluorescent silica nanoparticles (NPs) doped with inert dyes, which are organic fluorophores that are strongly fluorescent but are hydrophobic or lack a covalent binding group. The prepared NPs were mesoporous and the dye molecules were encapsulated in the pores via hydrophobic interaction with the CTAB template. The NPs were stable and highly fluorescent in aqueous solution, and have potential applications in bioanalysis and fluorescence encoding. | MU Xue WU ChuanLiu LAI JinPing CHEN JianBin ZHENG JinSheng LI Chong ZHAO YiBing | 2011 | Chinese Science Bulletin2011,56,31: | 5 |
| 10 | Polydopamine and collagen coated micro-grated polydimethylsiloxane for human mesenchymal stem cell culture显示文摘Natural tissues contain highly organized cellular architecture.One of the major challenges in tissue engineering is to develop engineered tissue constructs that promote cellular growth in physiological directionality.To address this issue,micro-patterned polydimethylsiloxane(PDMS)substrates have been widely used in cell sheet engineering due to their low microfabrication cost,higher stability,excellent biocompatibility,and most importantly,ability to guide cellular growth and patterning.However,the current methods for PDMS surface modification either require a complicated procedure or generate a non-uniform surface coating,leading to the production of poor-quality cell layers.A simple and efficient surface coating method is critically needed to improve the uniformity and quality of the generated cell layers.Herein,a fast,simple and inexpensive surface coating method was analyzed for its ability to uniformly coat polydopamine(PD)with or without collagen on micro-grated PDMS substrates without altering essential surface topographical features.Topographical feature,stiffness and cytotoxicity of these PD and/or collagen based surface coatings were further analyzed.Results showed that the PD-based coating method facilitated aligned and uniform cell growth,therefore holds great promise for cell sheet engineering as well as completely biological tissue biomanufacturing. | Dhavan Sharma Wenkai Jia Fei Long Shweta Pati Qinghui Chen Yibing Qyang Bruce Lee Chang Kyong Choi Feng Zhao | 2019 | Bioactive Materials2019,4,1: | 4 |

| 12 | Comparison on effect of hydrophobicity on the antibacterial and antifungal activities of α-helical antimicrobial peptides显示文摘HPRP-A1, a 15-mer α-helical cationic peptide, was derived from N-terminus of ribosomal protein L1 (RpL1) of Helicobacter pylori. In this study, HPRP-A1 was used as a framework to obtain a series of peptide analogs with different hydrophobicity by single amino acid substitutions in the center of nonpolar face of the amphipathic helix in order to systematically study the effect of hydrophobicity on biological activities of -helical antimicrobial peptides. Hydrophobicity and net charge of peptides played key roles in the biological activities of these peptide analogs; HPRP-A1 and peptide analogs with relative higher hydrophobicity exerted broad spectrum antimicrobial activity against Gram-negative bacteria, Gram-positive bacteria and pathogenic fungi, but also showed stronger hemolytic activity; the change of hydrophobicity and net charge of peptides had similar effects with close trend and extent on antibacterial activities and antifungal activities. This indicated that there were certain correlations between the antibacterial mode of action and the antifungal mode of action of these peptides in this study. The peptides exhibited antimicrobial specificity for bacteria and fungi, which provided potentials to develop new antimicrobial drugs for clinical practices. | ZHAO LianJing HUANG YiBing GAO Song CUI Yan HE Dan WANG Li CHEN YuXin | 2013 | Science China Chemistry2013,56,9: | 3 |

| 15 | Protection of 3'-methoxy-puerarin against focal brain ischemia and its association with c-fos expression显示文摘The present study established a rat model of focal brain ischemia by occlusion of the middle cerebral artery covered with FeCl3, and investigated the protective effect of 3'-methoxy-puerarin. Hippocampal and cortical c-fos gene expression was determined using in situ hybridization. Results showed that 3'-methoxy-puerarin reduced neurological deficit scores, cerebral infarcted zone and water content of brain tissues, dramatically increased the activity of catalase and glutathione peroxidase in the ischemia zone of the hippocampus, increased the activity of catalase in the cortex, decreased lipid peroxide and lactic acid contents in the hippocampus and cerebral cortex, and down-regulated c-fos gene expression in brain ischemic rats. Results demonstrated that 3'-methoxy-puerarin exhibited cerebroprotective effects against focal brain ischemia, which involved c-fos gene expression. | Sha Liu Yibing Zhang Guiyou Du Yong Zhao Haifeng Cui Chunyu Cao | 2011 | Neural Regeneration Research2011,6,27: | 2 |
