| 2 | Preliminary Study on Magnetic Induction Intensity Induced by Plasma During Hypervelocity Impact显示文摘An experimental system has been built to produce and measure the magnetic field in the backward ejected matter during hypervelocity impact.The designs of measurement system and coil,the choice of associated equipment,and the system calibration are also described in detail.The measurement of magnetic induction intensity for different given coil positions and azimuth angles are performed with two-stage light-gas gun.On condition that impact velocities are approximately equal and incidence angles are 45°,60° and 90° respectively,the relationship between average magnetic induction intensity and impact angle at different time spans is obtained.Experimental results show that the average magnetic induction intensity with incidence angle of 90° is larger than those with incidence angles of 45°and 60°. | Tang Enling Zhang Qingming Zhang Jian | 2009 | Chinese Journal of Aeronautics2009,22,4: | 13 |
| 3 | Segmentation of Hematoxylin-Eosin stained breast cancer histopathological images based on pixel-wise SVM classifier显示文摘Hematoxylin-Eosin(HE) staining is the routine diagnostic method for breast cancer(BC), and large amounts of HE stained histopathological images are available for analysis. It is emergent to develop computational methods to efficiently and objectively analyze these images, with the aim of providing potentially better diagnostic and prognostic information for BC. This work focuses on analyzing our in-house HE stained histopathological images of breast cancer tissues. Since tumor nests(TNs) and stroma morphological characteristics can reflect the biological behaviors of breast invasive ductal carcinoma(IDC), accurate segmentation of TNs and the stroma is the first step towards the subsequent quantitative analysis. We first propose a method based on the pixel-wise support vector machine(SVM) classifier for segmenting TNs and the stroma, then extract four morphological characters related to the TNs from the images and investigate their relationships with the patients' 8-year disease free survival(8-DFS). The evaluation result shows that the classification based segmentation method is able to distinguish between TNs and stroma with 87.1% accuracy and 80.2% precision,suggesting that the proposed method is promising in segmenting HE stained IDC histopathological images. The Kaplan-Meier survival curves show that three morphological characters(number of TNs, total perimeter, and average area of TNs) in the images have statistical correlations with 8-DFS of the patients, illustrating that the segmented images can help to identify new morphological factors in IDC TNs for the prediction of BC prognosis. | QU AiPing CHEN JiaMei WANG LinWei YUAN JingPing YANG Fang XIANG QingMing MASKEY Ninu YANG GuiFang LIU Juan LI Yan | 2015 | Science China(Information Sciences)2015,58,9: | 12 |
| 4 | EXPERIMENTAL STUDY ON HIGH-SPEED CENTRIFUGAL PUMPS WITH DIFFERENT IMPELLERS显示文摘The experimental study is carded out on high-speed centrifugal pumps with three different impellers. The ex-perimental results and analysis show that high-speed centrifugal pumps with a closed complex impeller can achieve thehighest efficiency and the lowest head coefficient followed by those with half-open impeller and open-impeller, and canobtain much easily stable head-capacity characrastic curve, while those with a half-open complex impeller can't. Thecharacteristic curve with a open impeller is almost constant horizontal line before dropping sharply. The results also showthat the axial clearance between pump casing and impeller can influence greatly on the performance of centrifugal pumps. | Zhu Zuchao Chen YingState Key Laboratory of Fluid Power Transmission and Control, Zhejiang University,Hangzhou 310027, ChinaHuang Dunhui Jin Qingming Cangnan Special Pumps Co.Ltd of Zhejiang Province | 2002 | Chinese Journal of Mechanical Engineering2002,15,4: | 10 |
| 5 | Porphyromonas gingivalis disrupts vascular endothelial homeostasis in a TLR-NF-κB axis dependent manner显示文摘Cardiovascular disease is still the leading cause of mortality worldwide.Vascular endothelial dysfunction is viewed as the initial step of most cardiovascular diseases.Many studies have indicated that periodontal pathogens,especially Porphyromonas gingivalis,are closely correlated with vascular endothelial homeostasis,but the function of P.gingivalis and the underlying mechanisms are still elusive.To illuminate the effects and elucidate the mechanisms of P.gingivalis on endothelial structural integrity,we developed P.gingivalis infection models in vivo and in vitro.Endothelial cell proliferation,differentiation and apoptosis were detected.Here,we showed that P.gingivalis can impair endothelial integrity by inhibiting cell proliferation and inducing endothelial mesenchymal transformation and apoptosis of endothelial cells,which reduce the cell levels and cause the endothelium to lose its ability to repair itself.A mechanistic analysis showed that TLR antagonist or NF-κB signalling inhibitor can largely rescue the damaged integrity of the endothelium caused by P.gingivalis,suggesting that TLR-NF-κB signalling plays a vital role in vascular endothelial homeostasis destroyed by P.gingivalis.These results suggest a potential intervention method for the prevention and treatment of cardiovascular disease. | Mengru Xie Qingming Tang Shaoling Yu Jiwei Sun Feng Mei Jiajia Zhao Lili Chen | 2020 | International Journal of Oral Science2020,12,3: | 9 |

| 8 | Stress-induced CsPbBr3 nanocrystallization on glass surface:Unexpected mechanoluminescence and applications显示文摘In this work,we discovered an unexpected mechanoluminescence (ML) phenomena occurring when transforming amorphous into crystalline,due to the stress-induced precipitation of CsPbBr3 perovskite nanocrystals on glass surface.It is revealed that,unlike the conventional thermal-induced phase transformation mechanism,the breakage of bonding of glass network provides the energy for nucleation and growth,and the shear stress avoids the long-range migration of structural units for crystallization.Such unique ML phenomenon enables the visualization of dynamical force that is inaccessible by common strategy,and so,opens up some novel applications,such as the pressure-sensitive 'glassy pencil' to learn people's writing habits,and the pb^2+-detection with good sensitivity and selectivity.These findings not only demonstrate an effective route for the preparation of perovskite materials in a green,time-saving,low cost,and scalable way,enrich the knowledge of glass crystallization mechanism,but also exploit a useful avenue to quantitatively visualize the dynamical force. | Xiaoqiang Xiang Hang Lin Renfu Li Yao Cheng Qingming Huang Ju Xu Congyong Wang Xueyuan Chen Yuansheng Wang | 2019 | Nano Research2019,12,5: | 8 |
| 9 | Compact, submilliwatt, 2 × 2 silicon thermo-optic switch based on photonic crystal nanobeam cavities显示文摘We propose and experimentally demonstrate a 2×2 thermo-optic(TO) crossbar switch implemented by dual photonic crystal nanobeam(PCN)cavities within a silicon-on-insulator(SOI)platform.By thermally tuning the refractive index of silicon,the resonance wavelength of the PCN cavities can be red-shifted.With the help of the ultrasmall mode volumes of the PCN cavities,only~0.16 mW power is needed to change the switching state.With a spectral passband of 0.09 nm at the 1583.75 nm operation wavelength,the insertion loss(IL)and crosstalk(CT)performances were measured as IL(bar)=-0.2 dB,CT(bar)=-15 dB,IL(cross)=-1.5 dB,and CT(cross)=-15 dB.Furthermore,the thermal tuning efficiency of the fabricated device is as high as1.23 nm/mW. | HUANYING ZHOU CIYUAN QIU XINHONG JIANG QINGMING ZHU YU HE YONG ZHANG YIKAI SU RICHARD SOREF | 2017 | Photonics Research2017,5,2: | 8 |
| 10 | Construction and visualization of high-resolution three-dimensional anatomical structure datasets for Chinese digital human显示文摘The objective of the China Digital Human Project (CDH) is to digitize and visualize the anatomical structures of human body. In the project, a database with information of morphology, physical charac-teristics and physiological function will be constructed. The raw data of CDH which was completed in the Southern Medical University is employed. In Huazhong University of Science and Technology (HUST), the frozen section images are preprocessed, segmented, labeled in accordance with the major organs and tissues of human beings, and reconstructed into three-dimensional (3D) models in parallel on high performance computing clusters (HPC). Some visualization software for 2D atlas and 3D mod-els are developed based on the new dataset with high resolution (0.1mm×0.1mm×0.2mm). In order to share, release and popularize the above work, a website (www.vch.org.cn) is online. The dataset is one of the most important parts in the national information database and the medical infrastructure. | LI AnAn LIUQian ZENG ShaoQun TANG Lei ZHONG ShiZhen LUO QingMing | 2008 | Chinese Science Bulletin2008,53,12: | 7 |
| 11 | Q-switching of waveguide lasers based on graphene/WS_2 van der Waals heterostructure显示文摘We report on the operation of passively Q-switched waveguide lasers at 1 μm wavelength based on a graphene∕WS_2 heterostructure as a saturable absorber(SA). The gain medium is a crystalline Nd:YVO_4 cladding waveguide produced by femtosecond laser writing. The nanosecond waveguide laser operation at 1064 nm has been realized with the maximum average output power of 275 m W and slope efficiency of 37%. In comparison with the systems based on single WS_2 or graphene SA, the lasing Q-switched by a graphene∕WS_2 heterostructure SA possesses advantages of a higher pulse energy and enhanced slope efficiency, indicating the promisingapplications of van der Waals heterostructures for ultrafast photonic devices. | ZIQI LI CHEN CHENG NINGNING DONG CAROLINA ROMERO QINGMING LU JUN WANG JAVIER RODRíGUEZ VáZQUEZ DE ALDANA YANG TAN FENG CHEN | 2017 | Photonics Research2017,5,5: | 7 |
| 12 | Fabrication technique of micro/nano-scale speckle patterns with focused ion beam显示文摘The fabrication technique of micro/nano-scale speckle patterns with focused ion beam (FIB) system is studied for digital image correlation (DIC) measurement under a scanning electron microscope (SEM).The speckle patterns are fabricated by directly etching the counterpart of the specimen to the black part of a template.Mean intensity gradient is used to evaluate the quality of these SEM images of speckle patterns fabricated based on different templates to select an optimum template.The pattern size depending on the displacement measurement sensitivity is adjusted by altering the magnification of FIB according to the relation curve of the etching size versus magnification.The influencing factors including etching time and ion beam current are discussed.Rigid body translation tests and rotation tests are carried out under SEM to verify the reliability of the fabricated speckle patterns.The calculated values are in good agreement with the imposed ones. | LI YanJie XIE HuiMin LUO Qiang GU ChangZhi HU ZhenXing CHEN PengWan ZHANG QingMing | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,6: | 7 |
| 13 | Firing patterns of long-term cultured neuronal network on multi-electrode array显示文摘Spontaneous neuronal activity plays an important role in the development and plasticity of brain. To explore the developmental changes in the firing pattern of the neuronal networks in vitro, the hippocampal neurons were cultured on the multi-microelectrode array dish for over 14 weeks and the spontaneous activity was recorded. The results showed that random firing was observed in the 1st week and transformed into synchronized activity after two weeks, then tightly synchronized activity appeared in week 2 to 7 and finally the activities transformed into the random firing pattern. These results suggested three stages in the long-term development of neuronal network in vitro: the stage for connection, the stage of synchronized activity and the mature stage. Synchronized firing shown by spontaneous activity was an important phenomenon in high density cultured neuronal network and transformed patterns during development. | LI Xiangning ZHOU Wei LIU Man ZENG Shaoqun LUO Qingming | 2006 | Progress in Natural Science:Materials International2006,16,12: | 7 |
| 14 | Oxygenation,inflammatory response and lung injury during one lung ventilation in rabbits using inspired oxygen fraction of 0.6 vs.1.0显示文摘Maintaining adequate oxygenation during one-lung ventilation(OLV) requires high inspired oxygen fraction(FiO_2).However,high FiO_2 also causes inflammatory response and lung injury.Therefore,it remains a great interest to clinicians and scientists to optimize the care of patients undergoing OLV.The aim of this study was to determine and compare oxygenation,inflammatory response and lung injury during OLV in rabbits using FiO_2 of 0.6 vs.1.0.After 30 minutes of two-lung ventilation(TLV) as baseline,30 rabbits were randomly assigned to three groups receiving mechanical ventilation for 3 hours:the sham group,receiving TLV with 0.6 FiO_2;the 1.0 FiO_2 group,receiving OLV with 1.0 FiO_2;the 0.6 FiO_2 group,receiving OLV with 0.6 FiO_2.Pulse oximetry was continuously monitored and arterial blood gas analysis was intermittently conducted.Histopathologic study of lung tissues was performed and inflammatory cytokines and the mRNA and protein of nuclear factor kappa B(NF-κB) p65 were determined.Three of the 10 rabbits in the 0.6 FiO_2 group suffered hypoxemia,defined by pulse oximetric saturation(SpO_2) less than 90%.Partial pressure of oxygen(PaO_2),acute lung injury(ALI) score,myeloperoxidase(MPO),tumor necrosis factor-a(TNF-α),interleukin-6(IL-6),mRNA and protein of NF-kB p65 were lower in the 0.6 FiO_2group than in the 1.0 FiO_2 group.In conclusion,during OLV,if FiO_2 of 0.6 can be tolerated,lung injury associated with high FiO_2 can be minimized.Further study is needed to validate this finding in human subjects. | Zeping Xu Lianbing Gu Qingming Bian Pengyi Li Lijun Wang Jingyuan Zhang Yanning Qian | 2017 | The Journal of Biomedical Research2017,31,1: | 7 |
| 15 | RLS and LMS blind adaptive multi-user detection method and comparison in acoustic communication显示文摘RLS and LMS blind adaptive multi-user detection algorithm and multi-user detector was proposed to solve the problem of multi-user signal detection problem encountered in underwater acoustic communication networks.In simulation analysis,RLS and the LMS blind adaptive multi-user detector were designed and tested for synchronous and asynchronous multi-user communication process.The results of SIR comparison and MMSE comparison show that,both of the two methods can realize blind adaptive detection when any user change in multi-user communication,during this process,the training communication sequences are not needed.The RLS algorithm has about 5 dB higher in SIR compared with LMS algorithm,and the convergence velocity of RLS algorithm is also higher than LMS algorithm when the communication users change.RLS algorithm has better ability in multi-user detection than that of LMS algorithm,and it has great attraction and guiding significance for solving the problem of multiple access interference(MAI) in multi-user communication. | WANG Zhongqiu WANG Hongru MENG Qingming | 2015 | Instrumentation2015,2,2: | 7 |
| 16 | Phase I study of CAR-T cells with PD-1 and TCR disruption in mesothelin-positive solid tumors显示文摘Programmed cell death protein-1(PD-1)-mediated immunosuppression has been proposed to contribute to the limited clinical efficacy of chimeric antigen receptor T(CAR-T)cells in solid tumors.We generated PD-1 and T cell receptor(TCR)deficient mesothelin-specific CAR-T(MPTK-CAR-T)cells using CRISPR-Cas9 technology and evaluated them in a dose-escalation study.A total of 15 patients received one or more infusions of MPTK-CAR-T cells without prior lymphodepletion.No dose-limiting toxicity or unexpected adverse events were observed in any of the 15 patients.The best overall response was stable disease(2/15 patients).Circulating MPTK-CAR-T cells peaked at days 7–14 and became undetectable beyond 1 month.TCR-positive CAR-T cells rather than TCR-negative CAR-T cells were predominantly detected in effusion or peripheral blood from three patients after infusion.We further confirmed the reduced persistence of TCR-deficient CAR-T cells in animal models.Our results establish the preliminary feasibility and safety of CRISPR-engineered CAR-T cells with PD-1 disruption and suggest that the natural TCR plays an important role in the persistence of CAR-T cells when treating solid tumors. | Zhenguang Wang Na Li Kaichao Feng Meixia Chen Yan Zhang Yang Liu Qingming Yang Jing Nie Na Tang Xingying Zhang Chen Cheng Lianjun Shen Jiaping He Xun Ye Wei Cao Haoyi Wang Weidong Han | 2021 | Cellular & Molecular Immunology2021,18,9: | 7 |
| 17 | THE GLASS TRANSITION TEMPERATURE AND MICROSTRUCTURE OF POLYURETHANE/EPOXY RESIN INTERPENETRATING POLYMER NETWORKS NANOCOMPOSITES显示文摘Nanocomposites with various contents of organophilic montmorillonite (oMMT) have been prepared by adding oMMT to interpenetrating poly- mer networks (IPNs) of polyurethane and epoxy resin (PU/EP) which had been prepared by a sequential polymeric technique. DSC experiment indicates a novel phenomenon that the glass transition tem- perature (Tg) of the nanocomposites increases with the oMMT content up to 3 %, then decreases with further increasing oMMT content. In order to explain this phenomenon, crosslink density, hydrogen bond- ing in the hard segments, crystallization of the nanocomposites and the exfoliation degree of oMMT in the nanocomposites have been investigated by swelling method, FT-IR, XRD, SEM and TEM, re- spectively. The results indicate that the crosslink density and the hydrogen bonding index of the nanocomposites increase, but the crystallization de- gree of the nanocomposites decreases with increas- ing oMMT content. In addition, oMMT improves the network structure of PU/EP. | JIA Qingming ZHENG Maosheng SHEN Renjie CHEN Hongxiang | 2006 | Chinese Science Bulletin2006,51,3: | 7 |
| 18 | On-chip silicon photonic 2 × 2 mode-and polarization-selective switch with low inter-modal crosstalk显示文摘Mode-and polarization-division multiplexing offer new dimensions to increase the transmission capacity of optical communications. Selective switches are key components in reconfigurable optical network nodes. An on-chip silicon 2 × 2 mode-and polarization-selective switch that can route four data channels on two modes and two polarizations simultaneously is proposed and experimentally demonstrated for the first time, to the best of our knowledge. The overall insertion losses are lower than 8.6 d B. To reduce the inter-modal crosstalk, polarization beam splitters are added to filter the undesired polarizations or modes. The measured inter-modal andintra-modal crosstalk values are below-23.2 and-22.8 d B for all the channels, respectively. | YONG ZHANG YU HE QINGMING ZHU CIYUAN QIU YIKAI SU | 2017 | Photonics Research2017,5,5: | 7 |
| 19 | Improvement of water resistance of long afterglow SrAl_2O_4: Dy, Eu phosphor by coating with SiO_2 film显示文摘The long afterglow SrAl2O4:Dy,Eu phosphor is liable to hydrolyze in water with deterioration of the luminescent property. SrAl2O4:Dy,Eu phosphors were therefore heated at 60-90℃ in TEOS sol to form a surface gel and then heat-treated at 400℃ to obtain SiO2 coated phosphors. Observation by Transmission Electron Microscope (TEM) and X-ray photoelectron spectroscopy (XPS) shows that a thin silica film forms on the surface of the phosphors. The coating procedure can be illustrated by a four-step process and the transparent silica film can suppress the hydrolysis process, so that the luminescent properties of the phosphors are unimpaired or even better. | ZHANG Junying, CHEN Qingming, LIN Yuanhua, and ZHANG ZhongtaiState Key Laboratory of New Ceramics and Fine Processing, Department of Materials Science and Engineering, Tsinghua University,Beijing 100084, China | 2002 | Rare Metals2002,21,2: | 7 |
| 20 | Structure Analysis of Locking Mechanism of Gear-Rack Typed Ship-Lift显示文摘Contact nonlinear theory was researched. Contact problem was transformed into optimization problem containing Lagrange multiplier, and unsymmetrical stiffness matrix was transformed into symmetrical stiffness matrix. A finite element analysis (FEA) model defining more than 300 contact pairs for long nut-short screw locking mechanism of a large-scale vertical gear-rack typed ship-lift was built. Using augmented Lagrange method and symmetry algorithm of contact element stiffness, the FEA model was analyzed, and the contact stress of contact interfaces and the von Mises stress of key parts were obtained. The results show that the design of the locking mechanism meets the requirement of engineering, and this method is effective for solving large scale nonlinear contact pairs. | SHI Duanwei WU Qingming ZHANG Zhiqiang | 2006 | Wuhan University Journal of Natural Sciences2006,11,3: | 6 |
