| 1 | Design of Robot Welding Seam Tracking System with Structured Light Vision显示文摘Robot welding is an important developing direction of welding automation and intelligentization, and automatic seam tracking technology is one of principal research domains. Nowadays, seam tracking system with structured light vision becomes a hot research. Structured light vision seam tracking products abroad are generally very expensive and can only be applied on special occasions. In China, the research of structured light vision seam tracking system is still just on the stage of experiments. A robot real-time seam tracking system with line structured light vision is designed. The hardware system is set up, a filtering method for line structure seam image is improved, and compared with common filtering, it has better effect and characteristic of real time. Two methods, fast template matching and fast Hough transform, to recognize the image coordinates of seam center are improved. Two new image recognition methods, structure element matching and corner detecting, are proposed. The comparison of seam image recognition shows that fast template matching and corner detecting are more precise and stable than the other two methods, and corner detecting is the best in real time. A simultaneous calibration for camera parameters and robot hand-eye is also proposed, and calculation shows that the calibration is effective and feasible. The robot seam tracking tests for linear and folded lap-joint are performed, which are based on the above four image recognition methods, and the results indicate that four image recognition methods are all applicable to real-time seam tracking, and the whole system sufficed for the requirements of real-time seam tracking. Automatic seam tracking with line structured light vision is feasible and has good versatility. | LIU Suyi WANG Guorong ZHANG Hua JIA Jianping | 2010 | Chinese Journal of Mechanical Engineering2010，23，4： | 17 |
| 2 | MiR-146a-5p targeting SMAD4 and TRAF6 inhibits adipogenensis through TGF-β and AKT/mTORC1 signal pathways in porcine intramuscular preadipocytes显示文摘Background: Intramuscular fat(IMF) content is a vital parameter for assessing pork quality. Increasing evidence has shown that microRNAs(miRNAs) play an important role in regulating porcine IMF deposition. Here, a novel miRNA implicated in porcine IMF adipogenesis was found, and its effect and regulatory mechanism were further explored with respect to intramuscular preadipocyte proliferation and differentiation.Results: By porcine adipose tissue miRNA sequencing analysis, we found that miR-146a-5p is a potential regulator of porcine IMF adipogenesis. Further studies showed that miR-146a-5p mimics inhibited porcine intramuscular preadipocyte proliferation and differentiation, while the miR-146a-5p inhibitor promoted cell proliferation and adipogenic differentiation. Mechanistically, miR-146a-5p suppressed cell proliferation by directly targeting SMAD family member 4(SMAD4) to attenuate TGF-β signaling. Moreover, miR-146a-5p inhibited the differentiation of intramuscular preadipocytes by targeting TNF receptor-associated factor 6(TRAF6) to weaken the AKT/mTORC1 signaling downstream of the TRAF6 pathway.Conclusions: MiR-146a-5p targets SMAD4 and TRAF6 to inhibit porcine intramuscular adipogenesis by attenuating TGF-β and AKT/mTORC1 signaling, respectively. These findings provide a novel miRNA biomarker for regulating intramuscular adipogenesis to promote pork quality. | Que Zhang Rui Cai Guorong Tang Wanrong Zhang Weijun Pang | 2021 | Journal of Animal Science and Biotechnology2021，12，1： | 10 |
| 3 | Force-induced charge carrier storage:a new route for stress recording显示文摘Stress sensing is the basis of human-machine interface,biomedical engineering,and mechanical structure detection systems.Stress sensing based on mechanoluminescence(ML)shows significant advantages of distributed detection and remote response to mechanical stimuli and is thus expected to be a key technology of next-generation tactile sensors and stress recorders.However,the instantaneous photon emission in ML materials generally requires real-time recording with a photodetector,thus limiting their application fields to real-time stress sensing.In this paper,we report a force-induced charge carrier storage(FICS)effect in deep-trap ML materials,which enables storage of the applied mechanical energy in deep traps and then release of the stored energy as photon emission under thermal stimulation.The FICS effect was confirmed in five ML materials with piezoelectric structures,efficient emission centres and deep trap distributions,and its mechanism was investigated through detailed spectroscopic characterizations.Furthermore,we demonstrated three applications of the FICS effect in electronic signature recording,falling point monitoring and vehicle collision recording,which exhibited outstanding advantages of distributed recording,longterm storage,and no need for a continuous power supply.The FICS effect reported in this paper provides not only a breakthrough for ML materials in the field of stress recording but also a new idea for developing mechanical energy storage and conversion systems. | Yixi Zhuang Dong Tu Changjian Chen Le Wang Hongwu Zhang Hao Xue Conghui Yuan Guorong Chen Caofeng Pan Lizong Dai Rong-Jun Xie | 2020 | Light(Science & Applications)2020，9，1： | 10 |
| 4 | Graph Regularized L_p Smooth Non-negative Matrix Factorization for Data Representation显示文摘This paper proposes a Graph regularized Lpsmooth non-negative matrix factorization(GSNMF) method by incorporating graph regularization and L_p smoothing constraint, which considers the intrinsic geometric information of a data set and produces smooth and stable solutions. The main contributions are as follows: first, graph regularization is added into NMF to discover the hidden semantics and simultaneously respect the intrinsic geometric structure information of a data set. Second,the Lpsmoothing constraint is incorporated into NMF to combine the merits of isotropic(L_2-norm) and anisotropic(L_1-norm)diffusion smoothing, and produces a smooth and more accurate solution to the optimization problem. Finally, the update rules and proof of convergence of GSNMF are given. Experiments on several data sets show that the proposed method outperforms related state-of-the-art methods. | Chengcai Leng Hai Zhang Guorong Cai Irene Cheng Anup Basu | 2019 | IEEE/CAA Journal of Automatica Sinica2019，6，2： | 9 |
| 5 | Genotype variations in accumulation of cadmium and lead in celery (Apium graveolens L.) and screening for low Cd and Pb accumulative cultivars显示文摘To help reduce risks of heavy metal pollution, two pot experiments were conducted to investigate the variations, transfer potential, and stability of Cadmium (Cd) and Lead (Pb) accumulations in celery (Apium graveolens L.) and to screen for low Cd and Pb accumulative cultivars. The maximum differences in shoot Cd concentration were 4.7-fold under low-Cd exposure and 3.3-fold under high-Cd exposure. These genotype variations in Cd accumulation are sufficiently large to help reduce Cd contamination risk in soil by using the Low-Cd-Accumulative genotypes. Cd accumulation of the Low-Cd-Accumulative genotypes is significantly positive correlated with Pb accumulation. Evidence obtained proves that Cd and Pb accumulations in celery are stable and genotype-dependent at the cultivar level. The presence of high-Pb contamination in soil promoted Cd accumulation in shoots of celery. Celery is considered a species with high risks in Cd pollution and low risks in Pb pollution. Among the tested cultivars, cv. Shuanggang- kangbing (SGKB) had the lowest shoot Cd and Pb accumulating abilities, and thus is the most important material for breeding of pollution-safe cultivars (PSCs) to minimize Cd and Pb accumulations in celery. | Kun ZHANG Jianbing WANG Zhongyi YANG Guorong XIN Jiangang YUAN Junliang XIN Charlie HUANG | 2013 | Frontiers of Environmental Science & Engineering2013，7，1： | 9 |
| 6 | Multiple Dolomitization and Fluid Flow Events in the Precambrian Dengying Formation of Sichuan Basin, Southwestern China显示文摘The Precambrian Dengying Formation is a set of large-scale, extensively dolomitized, carbonate reservoirs occurring within the Sichuan Basin. Petrographic and geochemical studies reveal dolomitization was a direct result of precipitation by chemically distinct fluids occurring at different times and at different intensities. Based on this evidence, dolomitization and multiple fluid flow events are analyzed, and three types of fluid evolution models are proposed. Results of analysis show that Precambrian Dengying Formation carbonates were deposited in a restricted peritidal environment(630–542 Ma). A high temperature and high Mg^(2+) concentration seawater was a direct result of dolomitization for the micrite matrix, and for fibrous aragonite in primary pores. Geochemical evidence shows low δ^(18)O values of micritic dolomite varying from-1.29‰ to-4.52‰ PDB, abundant light rare earth elements(REEs), and low dolomite order degrees. Microbes and meteoric water significantly altered dolomite original chemical signatures, resulting in algal micritic dolomite and the fine-grained, granular, dolosparite dolomite having very negative δ^(18)O values. Finely crystalline cement dolomite(536.3–280 Ma) and coarsely crystalline cement dolomite have a higher crystallization degree and higher order degree. The diagenetic sequence and fluid inclusion evidence imply a linear correlation between their burial depth and homogenization temperatures, which closely resemble the temperature of generated hydrocarbon. Compared with finely crystalline dolomite, precipitation of coarsely crystalline dolomite was more affected by restricted basinal fluids. In addition, there is a trend toward a more negative δ^(18)O value, higher salinity, higher Fe and Mn concentrations, REE-rich. Two periods of hydrothermal fluids are identified, as the exceptionally high temperatures as opposed to the temperatures of burial history, in addition to the presence of high salinity fluid inclusions. The early hydrothermal fluid flow event was characterized by hot magnesium-and silicon-rich fluids, as demonstrated by the recrystallized matrix dolomite that is intimately associated with flint, opal, and microcrystalline quartz in intergranular or intercrystalline pores. This event was likely the result of a seafloor hydrothermal chimney eruption during Episode I of the Tongwan Movement(536.3±5.5 Ma). In contrast, later hydrothermal fluids, which caused precipitation of saddle dolomite, were characterized by high salinity(15–16.05 wt% NaCl equivalent) and homogenization temperatures(250 to 265°C), δ^(18)O values that were more enriched, and REE signatures. Geochemical data and the paragenetic sequence indicate that this hydrothermal fluid was related to extensive Permian large igneous province activity(360–280 Ma). This study demonstrates the presence of complicated dolomitization processes occurring during various paleoclimates, tectonic cycles, and basinal fluids flow; results are a useful reference for these dolomitized Precambrian carbonates reservoirs. | PENG Bo LI Zongxing LI Guorong LIU Chenglin ZHU Shifa ZHANG Wang ZUO Yinhui GUO Yingchun WEI Xiaojie | 2018 | Acta Geologica Sinica(English Edition)2018，92，1： | 5 |

| 9 | Weakened anisotropy of mechanical properties in rolled ZK60 magnesium alloy sheets with elevated deformation temperature显示文摘The rolling direction(RD) and the transverse direction(TD) samples were obtained from an as-rolled ZK60 magnesium alloy sheet with strong anisotropy of initial texture and their mechanical properties were tested at various deformation temperatures. Meanwhile, the microstructure and texture of these samples after fracture were investigated. Results revealed that a higher flow stress along the RD than that along the TD at room temperature were ascribed to the strong anisotropy of transitional texture, and this texture effect was remarkably weakened with the increase of deformation temperature. Deformation structure was dominant at 100?C, and was replaced by dynamic recrystallization structure when the deformation temperature increased to 200?C and 300?C. The texture presented a strong texture(transitional texture in the RD sample and basal texture in the TD sample) at 100?C, but its intensity visibly decreased and texture components became more disperse at 200?C and 300?C. These microstructure and texture results were employed in conjunction with calculated results to argue that raising deformation temperature could increase the activity of non-basal slip by tailoring the relative critical resolved shear stress of each deformation mode and finally result in low texture effect on mechanical anisotropy. | Wenke Wang Wenzhen Chen Wencong Zhang Guorong Cui Erde Wang | 2018 | Journal of Materials Science & Technology2018，34，11： | 3 |

| 11 | The study on three-dimensional numerical model and fronts of the Jiulong Estuary and the Xiamen Bay显示文摘Applying the methods of on-site observation and dynamic model, the research on the fronts at the Jiulong Estuary has been carried out, during which spatial and temporal distribution, dynamic characteristics and formation mechanism of salinity fronts are analyzed and discussed. The research shows that the estuarine fronts mainly lie in the area from the Jiyu Islet to the Haimen Island, outside of Yuweizai to Hulishan cross-section, the near coast of Yuweizai and the south of the Songyu-Gulangyu Channel. The fronts in the former two regions are formed directly by plume, while the one near the coast of Yuweizai is a tidal intrusion front caused by flood current and the one at the south of the Songyu-Gulangyu Channel is the result of current shear transformation. Under normal circumstances, fresh water of the Jiulong River mainly influences the inside of the Xiamen Bay, and when it is in typhoon seasons, plume front can affect the Taiwan Strait and has an effect on the biogeochemical processes in the strait. | LUO Zhibin PAN Weiran LI Li ZHANG Guorong | 2012 | Acta Oceanologica Sinica2012，31，4： | 3 |

| 13 | Peroxidase-mimicking evodiamine/indocyanine green nanoliposomes for multimodal imaging-guided theranostics for oral squamous cell carcinoma显示文摘Here,evodiamine(EVO)and the photosensitizer indocyanine green(ICG)were integrated into a liposomal nanoplatform for noninvasive diagnostic imaging and combinatorial therapy against oral squamous cell carcinoma(OSCC).EVO,as an active component extracted from traditional Chinese medicine,not only functioned as an antitumor chemotherapeutic agent but was also capable of 68Ga-chelation,thus working as a contrast agent for positron emission tomography/computed tomography(PET/CT)imaging.Moreover,EVO could exhibit peroxidase-like catalytic activity,converting endogenous tumor H2O2 into cytotoxic reactive oxygen species(ROS),enabling Chemo catalytic therapy beyond the well-known chemotherapy effect of EVO.As proven by in vitro and in vivo experiments,guided by optical imaging and PET/CT imaging,we show that the theragnostic liposomes have a significant inhibiting effect on in situ tongue tumor through photodynamic therapy combined with chemodynamic chemotherapy. | Zheng Wei Huihui Zou Gongyuan Liu Chuanhui Song Chuanchao Tang Sheng Chen Guorong Zhang Jianchuan Ran Yufeng Wang Xiteng Yin Yu Cai Wei Han | 2021 | Bioactive Materials2021，6，7： | 2 |
| 14 | Management Algorithm for Prevention of Mother-to-child Transmission of Hepatitis B Virus(2022)显示文摘The World Health Organization(WHO)has set the goal of eliminating hepatitis as a threat to public health by 2030.Blocking mother-to-child transmission(MTCT)of hepatitis B virus(HBV)is not only the key to eliminating viral hepatitis,but also a hot issue in the field of hepatitis B prevention and treatment.To standardize the clinical management of preventing MTCT of HBV and achieve zero HBV infection among infants,the Chinese Foundation for Hepatitis Prevention and Control organized experts to compile a management algorithm for prevention of MTCT of HBV based on the latest research progress and guidelines,including 10 steps of pregnancy management and postpartum follow-up,among which screening,antiviral treatment,and infant immunization are its core components. | Zhihua Liu Zhongdan Chen Fuqiang Cui Yang Ding Yunfei Gao Guorong Han Jidong Jia Jie Li Zengde Li Yingxia Liu Qing Mao Ailing Wang Wei Wang Lai Wei Jianhong Xia Qing Xie Xizhong Yang Xueru Yin Hua Zhang Liaoyun Zhang Wenhong Zhang Hui Zhuang Xiaoguang Dou Jinlin Hou | 2022 | Journal of Clinical and Translational Hepatology2022，10，5： | 2 |

| 16 | An imputed whole-genome sequence-based GWAS approach pinpoints causal mutations for complex traits in a specific swine population显示文摘Sequencing-based genome-wide association studies(GWAS) have facilitated the identification of causal associations between genetic variants and traits in diverse species. However, it is cost-prohibitive for the majority of research groups to sequence a large number of samples. Here, we carried out genotype imputation to increase the density of single nucleotide polymorphisms in a large-scale Swine F;population using a reference panel including 117 individuals, followed by a series of GWAS analyses. The imputation accuracies reached 0.89 and 0.86 for allelic concordance and correlation, respectively. A quantitative trait nucleotide(QTN) affecting the chest vertebrate was detected directly, while the investigation of another QTN affecting the residual glucose failed due to the presence of similar haplotypes carrying wild-type and mutant allelesin the reference panel used in this study. A high imputation accuracy was confirmed by Sanger sequencing technology for the most significant loci. Two candidate genes,CPNE5 and MYH3, affecting meat-related traits were proposed. Collectively, we illustrated four scenarios in imputation-based GWAS that may be encountered by researchers, and our results will provide an extensive reference for future genotype imputation-based GWAS analyses in the future. | Guorong Yan Xianxian Liu Shijun Xiao Wenshui Xin Wenwu Xu Yiping Li Tao Huang Jiangtao Qin Lei Xie Junwu Ma Zhiyan Zhang Lusheng Huang | 2022 | Science China(Life Sciences)2022，65，4： | 2 |
