| 1 | 新时代中国公共体育服务的层级化建构显示文摘在新时代的背景下,以社会分层理论为立论基础和研究基点,提出了公共体育服务'层级化'的观点,文章在分析基本内涵的基础上认为,以具有多元化体育需求的公众为服务对象的公共体育服务,需要具备实效性、适切性、均等性的特征。基于这样的现实,公共体育服务的'层级化'要在规划设计层面坚持'顶层设计'与'基层地气'的结合,在政府角色层面'掌舵'与'服务'的统合,在体系运行层面坚持'整体'与'局部'的统一。可从拓宽公共体育服务来源、依恃中西方社会分层理论、进行'层级化'的规划设计和统筹布局、建立'政府+社会'的评价反馈机制、建立配套制度6个路径实现公共体育服务的层级化。 | 王洪珅 YAO Wanxiang 黄亚玲 | 2021 | 成都体育学院学报2021，47，2： | 7 |
| 2 | An Intelligent Fault Diagnosis Method of Multi-Scale Deep Feature Fusion Based on Information Entropy显示文摘For a single-structure deep learning fault diagnosis model,its disadvantages are an insufficient feature extraction and weak fault classification capability.This paper proposes a multi-scale deep feature fusion intelligent fault diagnosis method based on information entropy.First,a normal autoencoder,denoising autoencoder,sparse autoencoder,and contractive autoencoder are used in parallel to construct a multi-scale deep neural network feature extraction structure.A deep feature fusion strategy based on information entropy is proposed to obtain low-dimensional features and ensure the robustness of the model and the quality of deep features.Finally,the advantage of the deep belief network probability model is used as the fault classifier to identify the faults.The effectiveness of the proposed method was verified by a gearbox test-bed.Experimental results show that,compared with traditional and existing intelligent fault diagnosis methods,the proposed method can obtain representative information and features from the raw data with higher classification accuracy. | Zhiwu Shang Wanxiang Li Maosheng Gao Xia Liu Yan Yu | 2021 | Chinese Journal of Mechanical Engineering2021，34，4： | 4 |
| 3 | Arabidopsis ENOR3 regulates RNAi-mediated antiviral defense显示文摘Viruses can infect host plants to cause severe diseases and substantial agricultural loss, while plants have evolved RNA interference(RNAi) strategy to defend against viral infection. Despite enormous efforts, only a few host proteins in RNAi pathway were shown to mediate antiviral defense, including RNA-dependent RNA polymerase 1(RDR1), RDR6, DICER-LIKE 2(DCL2) and DCL4. In this study, we carried out a genetic screen for antiviral factors of RNAi pathway in Arabidopsis rdr6 background via inoculation with a 2 bdeficient Cucumber Mosaic Virus(CMV-D2b). We identified a mutant susceptible to CMV-D2b, referred to as enhancer of rdr6(enor) 3-1 rdr6, and found that ENOR3 encodes a functionally unknown protein with high homology to the mammalian Non Imprinted in Prader-Willi/Angelman(NIPA) magnesium transporters. ENOR3 inhibits accumulation of CMV-D2b and acts additively with RDR1, RDR6, DCL2 and DCL4 in antiviral defense. These results uncover that ENOR3 is a key component in antiviral RNAi pathway, and provide new insights into antiviral immunity. | Hua Gao Mai Yang Haitao Yang Yue Qin Biyun Zhu Gang Xu Chengyuan Xie Dewei Wu Xiaolin Zhang Wanxiang Li Jianbin Yan Susheng Song Tiancong Qi Shou-Wei Ding Daoxin Xie | 2018 | Journal of Genetics and Genomics2018，45，1： | 2 |
| 4 | Stereoselective Synthesis of Vinylboronates by Rh-Catalyzed Borylation of Stereoisomeric Mixtures显示文摘Summary of main observation and conclusion The stereoselective preparation of vinylboronates via rhodium-catalyzed borylation of E/Z mixtures of vinyl actetates is described, and this method was also extended to synthesis of vinyldiboronates. These transformations feature high functional group compatibility and mild reaction conditions. Control experiments support a mechanism that involved a Rh-catalyzed borylation-isomerization sequence. The isomerization of (Z)-vinylboronates to (E)-isomers was also demonstrated. | Shenhuan Li Jie Li Tianlai Xia Wanxiang Zhao | 2019 | Chinese Journal of Chemistry2019，37，5： | 2 |
| 5 | Three-dimensional topological insulators:A review on host materials显示文摘In recent years,three-dimensional topological insulators(3DTI) as a novel state of quantum matter have become a hot topic in the fields of condensed matter physics and materials sciences.To fulfill many spectacularly novel quantum phenomena predicted in 3DTI,real host materials are of crucial importance.In this review paper,we first introduce general methods of searching for new 3DTI based on the density-functional theory.Then,we review the recent progress on materials realization of 3DTI including simple elements,binary compounds,ternary compounds,and quaternary compounds.In these potential host materials,some of them have already been confirmed by experiments while the others are not yet.The 3DTI discussed here does not contain the materials with strong electron-electron correlation.Lastly,we give a brief summary and some outlooks in further studies. | FENG WanXiang YAO YuGui | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，12： | 2 |

| 12 | Mutually exclusive epigenetic modification on SIX6 with hypermethylation for precancerous stage and metastasis emergence tracing显示文摘Dear Editor,Aberrant DNA methylation gets involved in cancer initiation,progression,and recurrence,which in turn makes it an ideal cancer biomarker.Various methylation markers or their panels have been developed in diverse cancer types.However,the model-constructing based marker mining strategy and incompatibility of application have greatly impeded their ways to clinic.Thus,single methylation marker applicable to all/most cancer types and multiple clinical scenarios is desperately needed.The hope came from the unexpected observation that HIST1H4F was universally hypermethylated in all 17 cancer types;thus,we raised the concept of“Universal Cancer Only Marker(UCOM)”and established a paradigm for discovery and clinical application of UCOM.1 Recently,a novel UCOM,hypermethylated PCDHGB7,was identified and found to advance cervical cancer(CC)screening to the precancerous stage.2 During the screening of UCOM,we discerned a bunch of cancer cell-differentially methylated regions.1 Among them,sine oculis(SIX)homeobox family of transcription factors,which were found to function as tumorigenesis regulator by promoting epithelial-to-mesenchymal transition and metastasis recently in addition to their traditional roles in tissue formation and organogenesis,3 sparked our special attention.Herein,we interrogate whether SIX6 methylation could serve as a novel UCOM and its potential applications. | Shihua Dong Zhicong Yang Peng Xu Wanxiang Zheng Baolong Zhang Fangqiu Fu Zhanrui Mao Jianlin Yuan Haiquan Chen Wenqiang Yu | 2022 | Signal Transduction and Targeted Therapy2022，7，8： | 1 |

| 16 | Highly efficient separation of benzene+cyclohexane mixtures by extraction combined extractive distillation using imidazolium-based dicationic ionic liquids显示文摘Benzene(BEN)and cyclohexane(CYH),which have very close boiling points and a binary azeotrope,are the most difficult binary components in the separation of aromatic and non-aromatic hydrocarbons.This study further explored the separation mechanism and industrial application prospects of BEN+CYH mixtures separated by a dicationic ionic liquid(DIL)[C_(5)(MIM)_(2)][NTf_(2)]_(2) based on experimental research.The calculation results of the Conductor-like Screening model Segment Activity Coefficient(COSMO-SAC)model show that selectivity and solvent capacity of the DIL are significantly improved.The effects of different anions and cations on the micro-structure distribution and diffusion behavior of BEN+CYH system were investigated by quantum chemistry(QC)calculations and molecular dynamics(MD)simulations.The results indicate that the anion[NTf_(2)]_(2)has low polarity,uniform charge distribution,and a dual role of hydrogen bonding andπ-πbonding,and the cation[C_(5)(MIM)_(2)]^(2+) has stronger interaction with BEN and higher selectivity than conventional cations.The liquid-liquid extraction and extractive distillation(LLE-ED)process using an optimized 65 mol/mol DIL+35 mol/mol H_(2)O mixed solution as the extractant was proposed,which solved the problem of low product purity in the LLE process and high energy consumption in the ED process.Under the best operating conditions,the purity of CYH product was 99.9%,the purity of BEN product was 99.6%,the recovery rate of BEN reached 99.9%,and the recovery rate of DIL reached 99.9%.The heat-integrated LLE-ED process reduced total annual cost by 21.6%,and reduced CO_(2) emissions by 48.0%,which has broad industrial application prospects. | Wanxiang Zhang Wuji Zhao Shuhang Ren Yucui Hou Weize Wu | 2023 | Green Chemical Engineering2023，4，3： | 0 |

| 20 | Combating with extremely noisy samples in weakly supervised slot filling for automatic diagnosis显示文摘Slot filling,to extract entities for specific types of information(slot),is a vitally important modular of dialogue systems for automatic diagnosis.Doctor responses can be regarded as the weak supervision of patient queries.In this way,a large amount of weakly labeled data can be obtained from unlabeled diagnosis dialogue,alleviating the problem of costly and time-consuming data annotation.However,weakly labeled data suffers from extremely noisy samples.To alleviate the problem,we propose a simple and effective Co-WeakTeaching method.The method trains two slot filling models simultaneously.These two models learn from two different weakly labeled data,ensuring learning from two aspects.Then,one model utilizes selected weakly labeled data generated by the other,iteratively.The model,obtained by the Co-WeakTeaching on weakly labeled data,can be directly tested on testing data or sequentially fine-tuned on a small amount of human-annotated data.Experimental results on these two settings illustrate the effectiveness of the method with an increase of 8.03%and 14.74%in micro and macro f1 scores,respectively. | Xiaoming SHI Wanxiang CHE | 2023 | Frontiers of Computer Science2023，17，5： | 0 |
