| 3 | XPS Studies of Magnetic Multilayers显示文摘NiOx/N81Fe19 and Co/AlOx/Co magnetic multilayers were fabricated by reactive RF/DC magnetron sputtering on clean glass substrates and oxidized Si (100) substrates, respectively. The exchange biasing field (Hex) between NiOx, and Ni81Fe19 as a function of NiOx, oxidation states was studied by X-ray photoelectron spectroscopy (XPS). The oxidation states and the oxide thickness of Al layers in magnetic multilayer films consisting of Co/AlOx/Co were also analyzed. It is found that the Hex of NiOx/Ni81Fe19 films only depends on Ni2+ but not on Ni3+ or Ni. The bottom Co can be completely covered by depositing an Al layer thicker than 2.0 nm. The oxide layer was Al2O3, and its thickness was 1.15 nm. | Guanghua Yu, Hongchen Zhao, Jiao Teng, Chunlin Chai, Fengwu Zhu, Yang Xia, Shumin Chai Material Science and Engineering School, University of Science and Technology Beijing, Beijing 100083, China Microelectronics Center, Chinese Academy of Science, Beijin | 2001 | Journal of University of Science and Technology Beijing2001，8，3： | 2 |
| 4 | Research Progress on Effects of Stocking Density on Performance, Health and Welfare of Duck显示文摘Stocking density is an important factor for animal production performance.It appears particularly urgent and important to research systematically on stocking density for the dual restriction of environmental protection and animal welfare.This review dealt with the influence of stocking density on ducks'productivity and health through production performance,animal behavior and animal welfare,and analyzed the possible mechanism of high stocking density reducing production performance,resulting in abnormal behavior and stress,causing welfare and health problems.We consider that it might be associated with heat stress,more spatial competition(to gather the food,drinking water,sports area,etc.),as well as the quality deterioration of litter and house air caused by high stocking density.Finally,we put forward some suggestions on the study of stocking density's effects on ducks,and proposed the future work that need to be studied and problems that need to be solved imminently. | Chaowu YANG Chunlin YU Zengrong ZHANG Mohan QIU Huarui DU Qingyun LI Xiaosong JIANG Xia XIONG | 2020 | Agricultural Biotechnology2020，9，4： | 1 |
| 5 | Genetic and Breeding Progress Analysis on Five Pure Lines of Dahen Broiler显示文摘To timely modify breeding scheme and improve selection efficiency of Dahen broiler,genetic and breeding progress analysis on five pure lines was conducted. The results showed that the selection on breeding goal traits of each line was effective since 14 generations,especially the selection on growth traits did not cause adverse influence on reproductive performance. After the 6 thgeneration,main performances of each line maintained in higher level,but the breeding progress obviously declined. It illustrated that current breeding means was effective for maintaining and consolidating breeding goal traits of Dahen broiler,and it should timely adjust breeding scheme to obtain more genetic progress. | Chaowu YANG Huarui DU Zengrong ZHANG Mohan QIU Chunlin YU Lan LIU Xiaoyu JIANG Bo XIA Chenming HU Xiaoyan SONG Xia XIONG Li YANG Han PENG Qingyun LI Xiaosong JIANG | 2018 | Agricultural Biotechnology2018，7，5： | 1 |
| 6 | Astrocyte reactivity in related brain regions in a mouse model of MPTP-induced Parkinson's disease显示文摘BACKGROUND:Severe injury to dopaminergic neuronal cell bodies and their axon terminals in the substantia nigra pars compacta(SNC) has been observed in both Parkinson's disease(PD) patients or in 1-methy-4-phenyl-1,2,3,6-tetrahydropyrindine(MPTP)-induced PD animal models, but only slight injury occurs in the adjacent ventral tegmental area(VTA).The mechanisms underlying this selective injury remain poorly understood. OBJECTIVE:To comparatively observe astrocyte reactivity in the SNC,caudate putamen(CPu), VTA,and frontal association cortex(FrA). DESIGN,TIME AND SETTING:A cellular and molecular biology,randomized,controlled experiment was performed at the Institute of Neurobiology,Department of Human Anatomy, Medical School of Nantong University,between December 2006 and September 2008. MATERIALS:A total of 80 healthy adult male C57BL/6 mice were included in this study.MPTP was purchased from Sigma,USA. METHODS:Mice were randomly divided into a model group(n=64) and a sham-operated group (n=16).PD was induced in the mice from the model group by intraperitoneal injection of 20 mg/kg MPTP,once every three hours,for a total of 4 times. MAIN OUTCOME MEASURES:Tyrosine hydroxylase(TH)-immunoreactive neurons and glial fibrillary acidic protein(GFAP)-immunoreactive astrocytes were examined by dual immunofluorescence labeling.GFAP-immunoreactive astrocytes in the CPu and FrA were determined by immunofluorescent staining.GFAP mRNA expression in the SNC,CPu,VTA,and FrA was detected using real-time polymerase chain reaction.TH protein levels in the TH-immunoreactive axon terminals of the CPu and FrA were detected by Western blotting. RESULTS:Numbers of TH-immunoreactive neurons in the SNC,and TH protein level in the CPu, markedly decreased(by approximately 68%) 1 day after MPTP injection,and gradually increased at 3 days.Simultaneously,astrocyte reactivity was strengthened,in particular at 7 days.However, after MPTP injection,decreases in the numbers of TH-immunoreactive neurons in the VTA,and TH protein levels in the FrA,were less apparent(approximately 15%).Also,no obvious astrocyte reactivity was observed. CONCLUSION:In a mouse model of PD,astrocyte reactivity was apparent in the SNC and CPu, but not the VTA or FrA.In addition,astrocyte reactivity was greater in regions where injury to dopaminergic neurons was more severe. | Zhijun Zhang Chunlin Xia Yulin Dong Guangming Lü Juan Liu Lin Ding Hengjian Ni | 2009 | Neural Regeneration Research2009，4，2： | 1 |

| 8 | 中国超大城市大气中挥发性羰基化合物的健康风险评估(英文)显示文摘挥发性羰基化合物(c VOC)是大气光化学反应形成臭氧和灰霾等空气污染现象的重要前体物。超大城市是带动中国城市群快速发展的中心城市,经济发达,人口密集且数量超过1000万。在这些超大城市的大气环境中检出21种c VOC化合物,其总浓度年均值达55.6μg/m3,含量之高惊人。由于机动车尾气、工业排放、有机溶剂大量使用等原因,导致甲醛、乙醛、丙酮等三种健康危险物占据了中国城市大气c VOC总浓度的62.4%。采用日暴露水平、致癌风险和风险商等3种定量评价指标,发现北京、上海和广州大气环境中c VOC含量超标严重,具有较高的健康影响风险。在举办奥运会、亚运会和世博会等大型国际活动期间,中国式的空气质量保障运动仅能起到短期内缓解空气污染的疗效,但是难以长治久安。中国城市大气c VOC的健康风险问题应引起高度重视。 | 王伯光 Xia Ling Zhou Lei Wang Hao Zhang Chunlin Zhang Dachuan | 2014 | Social Sciences in China2014，35，3： | 1 |
| 9 | Ozone-Mediated Functionalization of Multi-Walled Carbon Nanotubes and Their Activities for Oxygen Reduction Reaction显示文摘The functionalization of multi-walled carbon nanotubes(MWCNTs)by ozone treatment has been systematically investigated by using Raman spectroscopy,transmission electron microscopy(TEM),Fourier transform infrared spectroscopy(FTIR),X-ray photoelectron spectroscopy(XPS),organic elemental analysis(OEA)and Boehm titration.The results showed that the functionalization process occurred at defective sites(opened mouths,tube caps,debris,etc.)before opening caps and truncating walls,and finally the graphitic structure was deteriorated.The surface oxygen content first increased with the treatment time but kept at around 8.0 wt%after 5 h.The analysis of the distribution of oxygen-containing groups revealed that phenolic hydroxyl was gradually converted to carboxyl and lactone.The carboxyl was found to play a pivotal role to reduce the over-potentials when we used the functionalized MWCNTs as the catalyst for oxygen reduction reaction(ORR). | Hengheng Xia Yexin Zhang Chunlin Chen Wenlin Wu Ken Yao Jian Zhang | 2016 | Journal of Materials Science & Technology2016，32，6： | 0 |

| 15 | Small RNA Sequencing Reveals Differentially Expressed piRNAs Related to Hypoxia in Tibetan Chickens显示文摘The relevance of genetic mechanism to the phenotype of hypoxic adaptation remains elusive.Tibetan chickens typically used to investigate the mechanism for the adaptation of hypoxia and the recognition of hypoxia-related piRNA remains an open issue.The purpose of this study was to illustrate whether the piRNAs were related to hypoxic adaptation.First of all,the differentially expressed piRNAs(DEpiRNAs)were identified through RNA sequencing between the Tibetan chickens and Daheng broilers.Subsequently,the target genes of DEpiRNAs were predicted and annotated by software.The network was constructed by Cytoscape.In our study,a total of 277 DEpiRNAs(33 down-regulated,244 up-regulated)were identified in the Tibetan chickens compared with the Daheng broilers.All of the 277 DEpiRNAs predicted 36658 targeted genes.Gene Ontology(GO)analysis showed that the target genes were significantly enriched in the biological process correlated with proliferation and apoptosis of cells,including cell cycle,mitochondrial outer membrane permeabilization,and positive regulation of stress-activated mitogen-activated protein kinase cascade.Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis implicated that the DEpiRNAs were mainly involved in immune and metabolism,including natural killer cell-mediated cytotoxicity,toll-like receptor signaling pathway and fatty acid metabolism.Furthermore,a predicted network with four piRNAs acted on 11 pathways via interacting with 22 target genes,in which piR-gga-1368839 regulated metabolic pathways by acting on DHCR24.In conclusion,we determined the DEpiRNAs in the Tibetan chickens and found that these piRNAs were associated with metabolism,which may be favorable for researching the biological adaptation to hypoxic stress. | Zengrong ZHANG Xiaosong JIANG Mohan QIU Chunlin YU Huarui DU Qingyun LI Han PENG Xia XIONG Xiaoyan SONG Chenming HU Jialei CHEN Chaowu YANG | 2022 | Agricultural Biotechnology2022，11，4： | 0 |
| 16 | Reading-related Brain Function Restored to Normal After Articulation Training in Patients with Cleft Lip and Palate:An fMRI Study显示文摘Cleft lip and/or palate(CLP)are the most common craniofacial malformations in humans.Speech problems often persist even after cleft repair,such that follow-up articulation training is usually required.However,the neural mechanism behind effective articulation training remains largely unknown.We used fMRI to investigate the differences in brain activation,functional connectivity,and effective connectivity across CLP patients with and without articulation training and matched normal participants.We found that training promoted task-related brain activation among the articulation-related brain networks,as well as the global attributes and nodal efficiency in the functional-connectivity-based graph of the network.Our results reveal the neural correlates of effective articulation training in CLP patients,and this could contribute to the future improvement of the post-repair articulation training program. | Liwei Sun Wenjing Zhang Mengyue Wang Songjian Wang Zhen Li Cui Zhao Meng Lin Qian Si Xia Li Ying Liang Jing Wei Xu Zhang Renji Chen Chunlin Li | 2022 | Neuroscience Bulletin2022，38，10： | 0 |
| 17 | Genetic and Breeding Progress Analysis on S06M Line of Dahen Broiler显示文摘The genetic and breeding progress of Dahen S06M line was analyzed, in order to improve the selection efficiency. The results showed that six generations of selection was effective in selecting main characters of S06M line, especially the selection of growth rate had no adverse effect on reproductive performance. All indicators of reproductive performance were improved in varying degrees during breeding, particularly the egg pro-duction at 68 weeks of age. The breeding progress of main target traits significantly slowed down after the second generation, but they still main-tained at higher levels and the characters of S06M tended to be stable. | Qiu Mohan Yang Chaowu Du Huarui Li Qingyun Xiong Xia Zhang Zengrong Hu Chenming Xia Bo Yu Chunlin Song Xiaoyan Yang Li Peng Han Jiang Xiaosong | 2018 | Animal Husbandry and Feed Science2018，10，4： | 0 |
| 18 | Fengyun-4 Geostationary Satellite-Based Solar Energy Nowcasting System and Its Application in North China显示文摘Surface solar irradiance(SSI)nowcasting(0-3 h)is an effective way to overcome the intermittency of solar energy and to ensure the safe operation of grid-connected solar power plants.In this study,an SSI estimate and nowcasting system was established using the near-infrared channel of Fengyun-4A(FY-4A)geostationary satellite.The system is composed of two key components:The first is a hybrid SSI estimation method combining a physical clear-sky model and an empirical cloudy-sky model.The second component is the SSI nowcasting model,the core of which is the derivation of the cloud motion vector(CMV)using the block-matching method.The goal of simultaneous estimation and nowcasting of global horizontal irradiance(GHI)and direct normal irradiance(DNI)is fulfilled.The system was evaluated under different sky conditions using SSI measurements at Xianghe,a radiation station in the North China Plain.The results show that the accuracy of GHI estimation is higher than that of DNI estimation,with a normalized root-mean-square error(nRMSE)of 22.4%relative to 45.4%.The nRMSE of forecasting GHI and DNI at 30-180 min ahead varied within 25.1%-30.8%and 48.1%-53.4%,respectively.The discrepancy of SSI estimation depends on cloud occurrence frequency and shows a seasonal pattern,being lower in spring-summer and higher in autumn-winter.The FY-4A has great potential in supporting SSI nowcasting,which promotes the development of photovoltaic energy and the reduction of carbon emissions in China.The system can be improved further if calibration of the empirical method is improved. | Chunlin HUANG Hongrong SHI Ling GAO Mengqi LIU Qixiang CHEN Disong FU Shu WANG Yuan YUAN Xiang′ao XIA | 2022 | Advances in Atmospheric Sciences2022，39，8： | 0 |
