| 1 | Inductance calculation for 3D microsolenoids with single-layer coils显示文摘Three-dimensional(3D) single-layer microcoils have always been a key element for electromagnetic systems;but they lack an easy and accurate method to calculate the inductance value for their complex 3D micro-structures. This paper employed a curve-fitting process to obtain the associated equation for the inductance value and geometric parameters based on the simulation results. The correction factors regarding helical pitch and wire diameter were reviewed,which are used for compensation in the Nagaoka formula. The simulation process numerically simulated the performance of the 3D microcoils using a FEM electro-magnetic-coupled analysis method. Comparison of the simulated inductance value and the Nagaoka formula was undertaken,which shows that the helical pitch and wire diameter contribute a main role in the calculation error. The derived formula was expressed in a concise form to precisely calculate the inductance value of 3D microsolenoids with single-layer coils. | LIU Keyin YANG Qing CHEN Feng ZHAO Yulong MENG Xiangwei SHAN Chao LI Yanyang | 2014 | Instrumentation2014，1，2： | 6 |
| 2 | IL-9 blockade attenuates inflammation in a murine model of methicillin-resistant Staphylococcus aureus pneumonia显示文摘Methicllin-resistant Staphylococcus aureus(MRSA)is an important etiology of pneumonia.Interleukin(L)-9 is a T helper 9(Th9)cytokine and participates in the pathogenesis of infectious diseases.Here,we investigated the role of IL9 by using an MRSA pneumonia animal model.The BALB/c mice underwent nasal inhalation with an ST239 MRSA strain to establish the mouse model of MRSA pneumonia,and a subset of mice were intravenously injected with IL9 neutral-izing antibody or immunoglobulin (lg)G.At 3 and 8 days postinfection,the peripheral blood,bronchioalveolar lavage fluid(BALF),and lung tissues were collected.The frequencies of Th9 cells and the levels of cytokines in peripheral blood,BALE and lung tissues were determined by flow cytometry and enzyme-linked immunosorbent assay(ELISA),respectively.The colony counts of MRSA in BALF and lung tissue were detected.The lung pathological changes were examined using hematoxylin and eosin staining.Data from flow cytometry,qRTPCR,and ELISA showed that MRSA infected mice exhibited higher frequency of Th9 cells and higher IL9 mRNA and protein levels in the peripheral blood,BALF and lung tissues of mice.In contrast,the neutralization of IL9 abrogated MRSA inoculation-induced Th9 cell generation and IL9 production in BALF and lung tissues.Furthermore,bacterial counting and histological examination showed that the numbers of bacteria in BALF and lungs and the lung pathological scores induced by MRSA inoculation were attenuated by the neutralization of IL9.Moreover,cell counting and ELISA results demonstrated that IL9 neutralization diminished the MRSA inoculation-induced count of neutrophils and macrophages and levels of pro-inflammatory cytokines in BALF Collectively,IL9 neutralization attenuated inflammation of MRSA pneumonia by regulating Th9/L9 expression. | Weihua Xu Keyin Tian Xiaoshuang Li Shihai Zhang | 2020 | Acta Biochimica et Biophysica Sinica2020，52，2： | 3 |
| 3 | Sculpturing spatiotemporal wavepackets with chirped pulses显示文摘Pulse shaping has become a powerful tool in generating complicated ultrafast optical waveforms to meet specific application needs.Traditionally,pulse shaping focuses on the temporal waveform synthesis.Recent interests in structuring light in the spatiotemporal domain rely on Fourier analysis.A space-to-time mapping technique allows us to directly imprint complex spatiotemporal modulation through taking advantage of the relationship between frequency and time of chirped pulses.The concept is experimentally verified through the generation of spatiotemporal optical vortex(STOV)and STOV lattice.The power of this method is further demonstrated by STOV polarity reversal,vortex collision,and vortex annihilation.Such a direct mapping technique opens tremendous potential opportunities for sculpturing complex spatiotemporal waveforms. | QIAN CAO JIAN CHEN KEYIN LU CHENHAO WAN ANDY CHONG QIWEN ZHAN | 2021 | Photonics Research2021，9，11： | 2 |

| 14 | Characters of variation of LURR during the earthquake sequence of Xinjiang显示文摘The theory of the loading/unloading response ratio (LURR) was applied to the Jiashi earthquake sequence which occurred at the beginning of 1997 in Xinjiang, and found that, before the earthquakes with relatively high magnitudes in the sequence, the ratio showed anomalies of high values. That is to say, the LURR theory can be applied to the short_term earthquake prediction in some cases, especially in the early period after a strong earthquake, such as the forecasts for some strong earthquakes in the Jiashi sequence. | Haitao Wang Keyin Peng Yongxian Zhang Yucang Wang Xiangchu Yin | 1998 | Chinese Science Bulletin1998，43，20： | 1 |
| 15 | Merging cobalt catalysis and electrochemistry in organic synthesis显示文摘There is an increasing demand of using the low-cost and sustainable cobalt to replace its noble congeners(rhodium and iridium)as reflected by the recent upsurge of cobalt catalysis in the diverse organic transformations.Since all the redox reactivity of cobalt catalysis highly relies on the capability of the interconversion between their oxidation states(most frequently+1,+2 and+3),electrochemistry perfectly meets such a require ment owing to its outstanding perfo rmance in the redox manipulation.In this review,we highlight the recent advances in the merger of cobalt catalysis and electrochemistry in organic synthesis. | Junsong Zhong Yi Yu Dongliang Zhang Keyin Ye | 2021 | Chinese Chemical Letters2021，32，3： | 1 |

| 19 | Litchi detection in the field using an improved YOLOv3 model显示文摘Due to the illumination,complex background,and occlusion of the litchi fruits,the accurate detection of litchi in the field is extremely challenging.In order to solve the problem of the low recognition rate of litchi-picking robots in field conditions,this study was inspired by the ideas of ResNet and dense convolution and proposed an improved feature-extraction network model named“YOLOv3_Litchi”,combining dense connections and residuals for the detection of litchis.Firstly,based on the traditional YOLOv3 deep convolution neural network and regression detection,the idea of residuals was to be put into the feature-extraction network to effectively avoid the problem of decreasing detection accuracy due to the excessive depths of the network layers.Secondly,under the premise of a good receptive field and high detection accuracy,the large convolution kernel was replaced by a small convolution kernel in the shallow layer of the network,thereby effectively reducing the model parameters.Finally,the idea of feature pyramid was used to design the network to identify the small target litchi to ensure that the shallow features were not lost and simultaneously reduced the model parameters.Experimental results show that the improved YOLOv3_Litchi model achieved better results than the classic YOLOv3_DarkNet-53 model and the YOLOv3_Tiny model.The mean average precision(mAP)score was 97.07%,which was higher than the 95.18%mAP of the YOLOv3_DarkNet-53 model and the 94.48%mAP of the YOLOv3_Tiny model.The frame frequency was 58 fps,which was higher than 29 fps of the YOLOv3_DarkNet-53 model.Compared with the classic Faster R-CNN model with the feature-extraction network VGG16,the mAP was increased by 1%,and the FPS advantage was obvious.Compared with the classic single shot multibox detector(SSD)model,both the accuracy and the running efficiency were improved.The results show that the improved YOLOv3_Litchi model had stronger robustness,higher detection accuracy,and less computational complexity for the identification of litchi in the field conditions,which should be helpful for litchi orchard precision management. | Hongxing Peng Chao Xue Yuanyuan Shao Keyin Chen Huanai Liu Juntao Xiong Hu Chen Zongmei Gao Zhengang Yang | 2022 | International Journal of Agricultural and Biological Engineering2022，15，2： | 0 |
| 20 | Home range and habitat use of male Reeves’s Pheasant(Syrmaticus reevesii)during winter in Dongzhai National Nature Reserve,Henan Province,China显示文摘Home range and habitat use of male Reeves’s pheasant(Syrmaticus reevesii)were studied during winter of 2001~2002 and 2002~2003 in the Dongzhai National Nature Reserve,Henan Province.Results from five individuals of Reeves’s pheasant with over 30 relocations,indicated that the average size of home range was 10.03±1.17 hm^(2) by Minimum Convex Polygon method,8.60±0.35 hm^(2) by 90%Harmonic Mean Transformation method,and 9.50±1.90 hm^(2) by 95%Fixed Kernel method.It was observed that the winter range is smaller than that in the breeding season.The mean core area of the home range was found to be 1.88±0.37 hm^(2).Although the habitat composition of the core area varied greatly for individuals,a large part of the habitats used were composed of conifer and broadleaf mixed forests,masson pine forests,fir forests,and shrubs.Habitat use within the study area was non-random,while habitats within home ranges were randomly used.Habitat use was dictated by tree diameter at breast height,shrub height and coverage at 2.0 m.The proximity between forests and shrubs were also found to be important in providing refuge for the birds during winter.Recommendations for conservation management include protecting the existing habitats in Dongzhai National Nature Reserve,increasing suitable habitat for Reeves’s Pheasant through artificial plantations(e.g.firs),and restoring some parts of the large shrub area into forests. | Xu Jiliang Zhang Xiaohui Zhang Zhengwang Zheng Guangmei Ruan Xiangfeng Zhang Keyin Xi Bo | 2006 | Frontiers in Biology2006，1，2： | 0 |
