| 1 | High-accuracy primary and transfer standards for radiometric calibration显示文摘The first research and experimental results obtained in China of high-accuracy radiometric calibration based on cryogenic radiometer are reported. Uncertainties of cryogenic radiometer and trap detectors at 7 wavelengths in the visible spectrum (488-786 nm) were less than 0.023% and 0.035% respectively, which proved the reasonability and possibility of establishing and transferring high-accuracy radiometric standards based on detectors. | Xiaobing Zheng Haoyu Wu Junping Zhang Yucheng Liu Wei Zhou Leyi Wang Yanli Qiao | 2000 | Chinese Science Bulletin2000，45，21： | 12 |
| 2 | How much information is needed in quantized nonlinear control?显示文摘Quantization rate is a crucial measure of complexity in determining stabilizability of control systems subject to quantized state measurements. This paper investigates quantization complexity for a class of nonlinear systems which are subjected to disturbances of unknown statistics and unknown bounds. This class of systems includes linear stablizable systems as special cases. Two lower bounds on the quantization rates are derived which guarantee input-to-state stabilizability for continuous-time and sampled-data feedback strategies, respectively. Simulation examples are provided to validate the results. | Chuang ZHENG Lin LI Leyi WANG Chanying LI | 2018 | Science China(Information Sciences)2018，61，9： | 6 |

| 4 | Substitutional doping in 2D transition metal dichalcogenides显示文摘Two-dimensional(2D)van der Waals transition metal dichalcogenides(TMDs)are a new class of electronic materials offering tremendous opportunities for advanced technologies and fundamental studies.Similar to conventional semiconductors,substitutional doping is key to tailoring their electronic properties and enabling their device applications.Here,we review recent progress in doping methods and understanding of doping effects in group 6 TMDs(MX2,M=Mo,W;X=S,Se,Te),which are the most widely studied model 2D semiconductor system.Experimental and theoretical studies have shown that a number of different elements can substitute either M or X atoms in these materials and act as n-or p-type dopants.This review will survey the impact of substitutional doping on the electrical and optical properties of these materials,discuss open questions,and provide an outlook for further studies. | Leyi Loh Zhepeng Zhang Michel Bosman Goki Eda | 2021 | Nano Research2021，14，6： | 4 |
| 5 | Preparation,characterization and biological properties of a novel bone block composed of platelet rich fibrin and a deproteinized bovine bone mineral显示文摘Alveolar bone defects caused by tooth loss often lead to challenges in implant dentistry,with a need for development of optimal bone biomaterials to predictably rebuild these tissues.To address this problem,we fabricated a novel bone block using platelet-rich fibrin(PRF)and Deproteinized Bovine Bone Mineral(DBBM),and characterized their mechanical and biological properties.The bone block was prepared by mixing DBBM,Liquid-PRF,and Solid-PRF fragments in various combinations as follows:(1)BLOCK-1 made with Solid-PRF fragments+DBBM,(2)BLOCK-2 made with Liquid-PRF+DBBM,(3)BLOCK-3 made with Solid-PRF fragments+Liquid-PRF+DBBM.The time for solidification and the degradation properties were subsequently recorded.Scanning electron microscopy(SEM)and tensile tests were carried out to investigate the microstructure and mechanical properties of each block.The bioactivity of the three groups towards osteoblast differentiation was also evaluated by culturing cells with the conditioned medium from each of the three groups including cell proliferation assay,cell migration assay,alkaline phosphatase(ALP)staining,and alizarin red staining(ARS),as well as by real-time PCR for genes encoding runt-related transcription factor 2(RUNX2),ALP,collagen type I alphal(COLIv41)and osteocalcin(OCN).BLOCK-3 made with Solid-PRF fragments+Liquid-PRF+DBBM had by far the fastest solidification period(over a 10-fold increase)as well as the most resistance to degradation.SEM and tensile tests also revealed that the mechanical properties of BLOCK-3 were superior in strength when compared to all other groups and further induced the highest osteoblast migration and osteogenic differentiation confirmed by ALP,ARS and real-time PCR.PRF bone blocks made through the combination of Solid-PRF fragments+Liquid-PRF+DBBM had the greatest mechanical and biological properties when compared to either used alone.Future clinical studies are warranted to further support the clinical application of PRF bone blocks in bone regeneration procedures. | Mengge Feng Yulan Wang Yan Wei Xiaoxin Zhang Leyi Xiao Zijjian Gong Masako Fujioka-Kobayashi Anton Sculean Richard J Miron Scott Froum Yufeng Zhang | 2022 | Fundamental Research2022，2，2： | 3 |
| 6 | Modification of Cellulose by Hydrophobic Long-chain Molecules: Advances and Prospects显示文摘Cellulose,a natural polymer material with abundant natural sources,is non-toxic,renewable,and biodegradable,making it one of the most promising green materials.Its inherent hydrophilicity dramatically limits the development and application of cellulose products.Hydrophobic modification can significantly change cellulose properties and endow it with additional functions depending on the types of modifying molecules.Controlled modification of cellulose by long-chain hydrophobic molecules is challenging.Significant advances took advantage of new reaction systems and copolymerization.This paper reviews recent innovations in long-chain cellulose hydrophobic modification.A brief value-adding assessment provides a reference for green changes of cellulose to make it fit for future applications. | Yuyuan Wang Haishan Zhang Leyi Lin Rui Wu Xiaohui Wang Junli Ren Chuanfu Liu Xiaoying Wang | 2020 | Paper And Biomaterials2020，5，3： | 3 |
| 7 | A Sensor Anonymity Enhancement Scheme Based on Pseudonym for Clustered Wireless Sensor Network显示文摘Security problem is an important issue for Wireless Sensor Network.The paper focuses on the privacy protection of WSN applications.An anonymity enhancement tactic based on pseudonym mechanism is presented for clustered Wireless Sensor Network,which provides anonymity for both the sensors within a cluster and the cluster head nodes.Simulation experiments are launched through NS2 platform to validate the anonymity performance.The theoretical analysis and empirical study imply that the proposed scheme based on pseudonym can protect the privacies of both the sensor nodes and the cluster head nodes.The work is valuable and the experimental results are convincible. | SHI Leyi FU Wenjing JIA Cong LIU Xin JIA Chunfu | 2014 | China Communications2014，11，9： | 2 |
| 8 | Early Miocene Paleoaltitude of the Tuotuohe Basin,Central-Northern Tibetan Plateau and its Tectonic Implications显示文摘Reconstruction of the paleoaltitude history of the Tibetan Plateau is critical for understanding the linkage between tectonics and its effect on regional and global climate change.Presently,most of the paleoaltitude studies are concentrated on the southern and southeastern part of the Tibetan Plateau,and few studies have been conducted in the central-northern part.In this paper we focused on the Wudaoliang Formation in the Tuotuohe Basin,central to northern Tibetan Plateau,to reconstruct paleoaltitude based on carbonate oxygen isotopes.The carbonate samples are primary or have experienced an early stage of digenesis.Based on the thermodynamic and empirical model results,the paleoaltitude of the Wudaoliang Formation is found to be around 2700–3260 m(average of 2980±280 m)in the early Miocene(~24 Ma).Integrating paleoaltitude results from Wudaoliang Basin and our results,we conclude that crustal shortening and tectonic activity were strong during the late Eocene to late Oligocene-early Miocene and relatively weak during the early Miocene in the central-northern Tibetan Plateau. | LI Leyi CHANG Hong GUAN Chong LIU Weiguo CAO Yunning | 2020 | Acta Geologica Sinica(English Edition)2020，94，5： | 2 |

| 10 | Antioxidant systems of aquatic macrophytes in three life forms:a case study in Lake Erhai,China显示文摘Antioxidant systems are vital in life activities of macrophytes. Species with diff erent life forms need to cope with distinct environments by modifying physiological characters, especially antioxidant systems. In order to find diff erences among life forms and consequence of lake eutrophication, we studied three antioxidant enzymes activity (superoxide dismutase (SOD), ascorbate oxidase (APX) and catalase (CAT)) and total soluble phenolics (TP) content in leaves of 26 macrophyte species in September 2013 in Lake Erhai, China. We found that antioxidation varied accordingly with life forms. The activities of SOD and APX in emergent macrophytes (EM) and floating-leaved macrophytes (FM) were much lower than those of submerged macrophytes (SM). On the contrary, TP content was much higher in EM and FM species. There was a negative correlation between TP and antioxidant enzyme activities (CAT and APX). The results suggested that EM and FM species rely on phenolics might to adapt to adverse environments (higher herbivores predation pressure and UV radiation intensity), while SM species more rely on antioxidant enzymes possibly due to lower demand for antioxidation and/or lack of light and inorganic C availability for phenolics synthesis. We also found FM species represent highest fitness in term of antioxidant system, which would lead to overgrowth of FM species and littoral zone bogginess during lake eutrophication. Finally, it is necessary to carry out the verification experiment under the control condition in the later stage, especially for the dominant ones in eutrophic lakes, to understand the exact adaptive mechanisms of them. | YUAN Changbo ZHU Tianshun CAO Te XI Yilong ZHANG Xiaolin NI Leyi | 2019 | Journal of Oceanology and Limnology2019，37，2： | 1 |

| 17 | A Point-to-Point Tracking Algorithm Based on the Theory of Floating Pixels显示文摘Based on the theory of floating pixels, a point-to-point tracking algorithm based on local features is presented. A novel texture-based feature set is proposed in a form of high dimensional vector which describes each single point. Point-to-point matching is applied in a way of vector operation at multiple scales. Each match is verified by variance analysis, and unreliable matches are corrected with candidates available. Experimental results demonstrate that this algorithm maintains strong robustness when target-appearance is varying and environment is complex. | WANG Shoujue JIANG Yuwen TAN Leyi | 2016 | Chinese Journal of Electronics2016，25，1： | 1 |
