| 1 | Numerical and experimental study of magnetic fluid seal with large sealing gap and multiple magnetic sources显示文摘To improve the pressure capability of magnetic fluid seal with more than a 0.25 mm single edge gap,a magnetic fluid sealing structure with multiple magnetic sources which has five permanent magnets was designed.Magnetic field distributions under the pole pieces of the magnetic fluid seal with single and multiple magnetic sources were simulated by finite element method and its sealing pressure difference could be calculated according to the theoretical formula of the magnetic fluid seal.The effects of sealing gap height and magnetic source amount on the sealing capability were investigated experimentally.The theoretical and experimental results were compared,analyzed and discussed.The results demonstrated that the magnetic fluid seal with multiple magnetic sources was an effective method to improve the sealing capability for the rotary shaft with large gaps.The theoretical results agreed well with the experimental results when the height of the single edge gap was equal to 0.4 mm.However,it was found that when the height of the single edge gap was larger than 0.4 mm,the difference between the theoretical values and experimental values increased with the gap height because part of magnetic source had less or even no effect on magnetic fluid sealing capability. | YANG XiaoLong ZHANG ZhiLi LI DeCai | 2013 | Science China(Technological Sciences)2013，56，11： | 10 |
| 2 | Differential equation dynamical system based assessment model in GNSS interoperability显示文摘With the development of Global Navigation Satellite System (GNSS),the idea of GNSS interoperability is born and has become the focus of study in the field of satellite navigation.The popularity for GNSS to augment the interoperability with the existing ones necessitates the study of the assessment algorithm of this idea.In this paper,an assessment algorithm for interoperability comprehensive benefits based on the differential equation dynamical system is discussed.There are two important aspects in GNSS that interoperability will affect:one is the performance advancement;the other one is the cost of adopting interoperability.While researching the complex relationship between the performance and cost,we found this relationship is similar as what between prey and predator in biomathematics,so the Lotka-Volterra model used to depict the prey-predator relationship is a felicitous tool.After building a differential dynamical model,we analyze the existence and stability of the positive equilibrium in the model.Then a Cost-Effective Function of GNSS is constructed based on the positive equilibrium,which is employed to assess the interoperability,qualitatively and quantitatively.Finally,the paper demonstrates the significance of the model and its application by citing a numerical example. | HAN Tao LU XiaoChun WANG Xue RAO YongNan ZOU DeCai YANG JianFei WU YangYang | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，6： | 3 |

| 4 | Low overhead design-for-testability for scan-based delay fault testing显示文摘An efficient design-for-testability (DFT) technique is proposed to achieve low overhead for scan-based delay fault testing. Existing techniques for delay test such as skewed-load or broadside make the test generation process complex and produce lower coverage for scan-based designs as compared with non-scan designs, whereas techniques such as enhanced-scan test can make the test easy but need an extra holding latch to add substantial hardware overhead. A new tri-state holding logic is presented to replace the common holding latch in enhanced-scan test to get a substantial low hardware overhead. This scheme can achieve low delay overhead by avoiding the holding latch on the critical timing scan path. What’s more, this method can also keep the state and signal activity in the combinational circuit from the scan during data scan-in operation to reduce the power dissipation. Experiment results on a set of ISCAS89 benchmarks show the efficiency of the proposed scheme. | Yang Decai Chen Guangju Xie Yongle | 2007 | Journal of Systems Engineering and Electronics2007，18，1： | 3 |

Luquan Yi and Miao Autonomous County,Yunnan Province,located in the high mountain and gorge area along Jinsha River,is one of the key counties of poverty alleviation and development with a wide range of poverty and a deep degree of poverty. The incidence of poverty is 22. 21%. Housing security is the focus,difficulty and emphasis of poverty alleviation in this county,the number of dilapidated houses is large,the type is complex,the transformation is difficult,and the implementation cost is high.Since the beginning of 2017,Luquan County has faced difficulties,explored in depth,pioneered and innovated,and completed the renovation of 54 801 dilapidated houses in an all-round way. It created a road full of characteristics and effectiveness of rural dilapidated housing transformation,and explored a set of effective scientific identification and accurate transformation models for rural dilapidated housing worthy of reference and promotion. Successful renovation of dilapidated houses,combined with industrial poverty alleviation,education poverty alleviation,health poverty alleviation and other accurate poverty alleviation measures,have made Luquan County win a decisive victory in the fight against poverty. By the end of December 2018,the incidence of poverty in the county had dropped to 0. 54%,and 115 poor villages( including 83 extremely poor villages) had successfully shaken off poverty. This paper analyzes and summarizes the concrete methods,main effects,characteristics and bright spots,successful experience,and reference significance of the scientific identification and precise transformation mode of rural dilapidated houses in this county,so as to provide a necessary reference for the transformation of rural dilapidated houses in Yunnan Province and even poor counties in similar provinces( cities and districts). | Zisheng YANG Renyi YANG Kaibo TIAN Zhenghong DAI Decai PAN Ying XIONG | 2019 | Asian Agricultural Research2019，11，2： | 3 |
| 6 | Isolation of a strong matrix attachment region (MAR) and identification of its function in vitro and in vivo显示文摘Inclusion of MARs in transgene cassettes enhances their expression and reduces position-effect variations in the transgenic host. Four new MARs (TM2, TM3, AM1 and AM2) were isolated from tobacco and Arabidopsis by PCR method. The nuclei isolated from suspension-cultured cells of rice were used to prepare nuclear matrix. With a characterized MAR (TM1) as a positive control, the Matrix-MAR interactions were tested by an in vitro binding assay to identify the DNA sequences as MARs and their binding strength to nuclear matrix in vitro was compared. The results showed that TM2 and TM3 had stronger binding strength than TM1. To determine the functions of the four new MARs in vivo, binary vectors pBI121 carrying a uidA GUS reporter gene were modified with direct repeat MARs inserted on both sides of the reporter gene cassette and were transferred into tobaccos via Agrobacterium-mediated transformation procedure. Quantitative GUS assays of the transgenic tobaccos showed that when flanking a GUS reporter gene | Kewei Zhang Jianmei Wang Guodong Yang Xingqi Guo Fujiang Wen Decai Cui Chengchao Zheng | 2002 | Chinese Science Bulletin2002，47，23： | 2 |
| 7 | An efficient papaya leaf distortion mosaic potyvirus vector for virus-induced gene silencing in papaya显示文摘Papaya(Carica papaya L.)is regarded as an excellent model for genomic studies of tropical trees because of its short generation time and its small genome that has been sequenced.However,functional genomic studies in papaya depend on laborious genetic transformations because no rapid tools exist for this species.Here,we developed a highly efficient virus-induced gene silencing(VIGS)vector for use in papaya by modifying an artificially attenuated infectious clone of papaya leaf distortion mosaic virus(PLDMV;genus:Potyvirus),PLDMV-E,into a stable Nimble Cloning(NC)-based PLDMV vector,pPLDMV-NC,in Escherichia coli.The target fragments for gene silencing can easily be cloned into pPLDMV-NC without multiple digestion and ligation steps.Using this PLDMV VIGS system,we silenced and characterized five endogenous genes in papaya,including two common VIGS marker genes,namely,phytoene desaturase,Mg-chelatase H subunit,putative GIBBERELLIN(GA)-INSENSITIVE DWARF1A and 1B encoding GA receptors;and the cytochrome P450 gene CYP83B1,which encodes a key enzyme involved in benzylglucosinolate biosynthesis.The results demonstrate that our newly developed PLDMV VIGS vector is a rapid and convenient tool for functional genomic studies in papaya. | Decai Tuo Pu Yan Guangyuan Zhao Hongguang Cui Guopeng Zhu Yang Liu Xiukun Yang He Wang Xiaoying Li Wentao Shen Peng Zhou | 2021 | Horticulture Research2021，8，1： | 2 |

| 12 | Hollow structures as drug carriers:Recognition,response,and release显示文摘Hollow structures have demonstrated great potential in drug delivery owing to their privileged structure,such as high surface-to-volume ratio,low density,large cavities,and hierarchical pores.In this review,we provide a comprehensive overview of hollow structured materials applied in targeting recognition,smart response,and drug release,and we have addressed the possible chemical factors and reactions in these three processes.The advantages of hollow nanostructures are summarized as follows:hollow cavity contributes to large loading capacity;a tailored structure helps controllable drug release;variable compounds adapt to flexible application;surface modification facilitates smart responsive release.Especially,because the multiple physical barriers and chemical interactions can be induced by multishells,hollow multishelled structure is considered as a promising material with unique loading and releasing properties.Finally,we conclude this review with some perspectives on the future research and development of the hollow structures as drug carriers. | Decai Zhao Nailiang Yang Lekai Xu Jiang Du Yang Yang Dan Wang | 2022 | Nano Research2022，15，2： | 1 |
| 13 | Precursor chemistry towards highly efficient and phase-stable red emitting CsPbI_(3) perovskite nanocrystals显示文摘All-inorganic cesium lead halide perovskite nanocrystals(CsPbX_(3),X=Cl,Br,I)have attracted considerable scientific and technological interest due to their precise bandgap tunability,high color purity and efficient luminescence.Nevertheless,their poor stability in harsh conditions such as moisture,ultraviolet(UV)light irradiation and high temperature,is a major obstacle for their further commercial applications.Herein,by simply using a new type of precursor,namely“HPbX_(3)”(X=Cl,Br,I),we can achieve the coordination equilibrium for Pb precursors during reaction and obtain high-quality perovskite nanocrystals with tremendously enhanced luminous efficiency and chemical stability based on hot-injection method.The prepared a-CsPbb nanocrystals exhibit an extremely high photoluminescence quantum yield of 96%and keep stable in air for more than two months without any post-synthesis treatment.Moreover,stability evaluations under UV light irradiation,water or thermal impact are also performed and the results show substantially improved stability of these nanocrystals as compared with the samples prepared using traditional Pbl_(2) as precursor.Through temperature-dependent(10-300 K)steady and transient spectral analysis combined with compositional measurements,it is revealed that the lower structural defect density,which is guaranteed by abundant halogen when using HPbX3 as precursor,is the most important reason for such performance enhancement. | Dejian Chen Decai Huang Mingwei Yang Kunyuan Xu Jie Hu Sisi Liang Haomiao Zhu | 2022 | Nano Research2022，15，1： | 0 |
| 14 | Engineering surface oxygen vacancy of mesoporous CeO_(2) nanosheets assembled microspheres for boosting solar-driven photocatalytic performance显示文摘Surface oxygen vacancy defects of mesoporous CeO_(2)nanosheets assembled microspheres(D-CeO_(2))are engineered by polymer precipitation,hydrothermal and surface hydrogenation strategies.The resultant D-CeO_(2)with a main pore diameter of 9.3 nm has a large specific surface area(~102.3 m^(2)/g)and high thermal stability.The mesoporous nanosheets assembled microsphere structure prevents the nanosheets from aggregation,which is beneficial to effective mass transfer and shortens the migration distance of charge carriers.After surface hydrogenation,the photoresponse extends to long wavelength region,combing with the band gap from 2.63 eV reduced to 2.39 eV.Under AM 1.5 G radiation,the photocatalytic degradation rate of tetracycline(TC)can be up to 99.99%,which is three times as high as that of pristine CeO_(2)microspheres.The excellent solar-driven photocatalytic performance can be attributed to the efficient surface oxygen vacancy engineering and the mesoporous nanosheets assembled microsphere structure,which narrows the band gap,shortens the migration distance of carriers,promotes the spatial separation of photogenerated electron-hole pairs and favors mass transfer.The strategy provides new insights for fabricating other high-efficient oxide photocatalysts. | Decai Yang Yachao Xu Kai Pan Chuanxin Yu Jiaxing Wu Mingxia Li Fan Yang Yang Qu Wei Zhou | 2022 | Chinese Chemical Letters2022，33，1： | 0 |

| 16 | 循环肿瘤细胞的检测方法及其在肺癌临床中的应用(英文)显示文摘Circulating tumor cells(CTCs) are tumor cells that enter the blood circulation after detaching from the primary tumor and can migrate to reach distant organs, where they can give rise to aggressive metastasis. Clinical studies have revealed that the presence of CTCs in peripheral blood is correlated with disease progression in lung cancer. However, as CTCs are rare cancer cells released from tumors into the bloodstream, both enrichment and sensitive detection methods are technically challenging. In order to best understand how CTCs are currently being deployed, this review mainly focuses on the different detection methods for CTCs. Furthermore, we will describe the clinical impact of circulating tumor cells in lung cancer and discuss their potential use as biomarker to guide the prognosis. | Minghui Zhang Decai Chi Shu Zhao Yan Wang Maopeng Yang Yan Wan | 2014 | The Chinese-German Journal of Clinical Oncology2014，13，10： | 0 |

| 18 | Enhanced Entropy-Based Resource Searching in Unstructured P2P Networks显示文摘How to find desired resources efficiently and accurately is one fundamental challenge of any unstructured P2 P networks, which is mainly involved some difficulties in the P2 P overlay topology, data representation in peers and routing mechanism. In this paper, we address the issue of resilient routing in unstructured P2 P networks. An efficient algorithm called Query routing tree(QRT) based on maximum mutual information is proposed to improve the performance of resource searching, which has tightly associated the resource contents of peers with the logical links in P2 P network that makes the query messages forwarded more effectively in similar peers and can hit more target resources faster. Additionally, we present an optimized routing scheme with the query conditions taken into account, to obtain the optimal routing tree with the minimal information gain from the candidate tree set so as to adapt to different query types more flexibly. The simulation results show the proposed QRT can reduce the search cost more effectively and maintain higher targets hit rate than existing typical algorithms such as Flooding, k-RW and APS. Finally, our optimized scheme is also proved to conduct high searching performance with nicer self-adaptability and scalability in unstructured P2 P networks. | GONG Weihua JIN Rong YANG Lianghuai HUANG Decai | 2015 | Chinese Journal of Electronics2015，24，2： | 0 |
| 19 | Original article Laparoscopic cholecystectomy based on Laennec approach via the cystic plate with lymphadenectomy in Calot's triangle for gallbladder neoplasms: Initial experience and technical details显示文摘Background:It is still challenging to define the exact stage of early gallbladder carcinoma with preoperative imaging.Generally,subserous gallbladder is dissected for the potential early gallbladder carcinoma,which may cause incomplete tumor resection or tumor spread especially for the patients with T2 stage.Here,we reported our experience and safety of Laennec approach via the cystic plate to dissect the whole gallbladder with lymphadenectomy in Calot's triangle for accurate diagnosis and stage in gallbladder neoplasms.Methods:The anatomical gap between Laennec capsule and the cystic plate serves as the landmark to dissect the whole gallbladder through Laennec approach.Laparoscopic cholecystectomy based on Laennec approach via the cystic plate,together with lymphadenectomy in Calot's triangle,was performed in 17 patients with gallbladder neoplasms.Results:All patients had less intraoperative bleeding,no gallbladder breakage,no bile leakage,and accurate intraoperative rapid pathological staging under the corresponding strategies.The duration of surgery was comparable to that of traditional laparoscopic cholecystectomy.Conclusion:Laparoscopic cholecystectomy based on Laennec approach via the cystic plate,together with lymphadenectomy in Calot's triangular is safe for gallbladder neoplasms.In the future,the prospective clinical trial is going on to confirm the feasibility and effectiveness of this approach. | Bin Ouyang Laizhu Zhang Yajuan Cao Zhongjie Xing Jin Peng Yang Yue Decai Yu | 2023 | iLIVER2023，2，4： | 0 |
