| 1 | Acute high-altitude hypoxic brain injury Identification of ten differential proteins显示文摘Hypobaric hypoxia can cause severe brain damage and mitochondrial dysfunction,and is involved in hypoxic brain injury.However,little is currently known about the mechanisms responsible for mitochondrial dysfunction in hypobaric hypoxic brain damage.In this study,a rat model of hypobaric hypoxic brain injury was established to investigate the molecular mechanisms associated with mitochondrial dysfunction.As revealed by two-dimensional electrophoresis analysis,16,21,and36 differential protein spots in cerebral mitochondria were observed at 6,12,and 24 hours post-hypobaric hypoxia,respectively.Furthermore,ten protein spots selected from each hypobaric hypoxia subgroup were similarly regulated and were identified by mass spectrometry.These detected proteins included dihydropyrimidinase-related protein 2,creatine kinase B-type,isovaleryl-CoA dehydrogenase,elongation factor Ts,ATP synthase beta-subunit,3-mercaptopyruvate sulfurtransferase,electron transfer flavoprotein alpha-subunit,Chain A of 2-enoyl-CoA hydratase,NADH dehydrogenase iron-sulfur protein 8 and tropomyosin beta chain.These ten proteins are all involved in the electron transport chain and the function of ATP synthase.Our findings indicate that hypobaric hypoxia can induce the differential expression of several cerebral mitochondrial proteins,which are involved in the regulation of mitochondrial energy production. | Jianyu Li Yuting Qi Hui Liu Ying Cui Li Zhang Haiying Gong Yaxiao Li Lingzhi Li Yongliang Zhang | 2013 | Neural Regeneration Research2013，8，31： | 6 |
| 2 | An energy-conserving two-way coupled mode model for underwater acoustic propagation显示文摘In order to avoid the energy non-conservation in two-way sound field calculations,which results from certain approximation of non-horizontal boundary,an energy-conserving twoway coupled mode propagation model is developed.During the derivation of this model,the non-horizontal boundary condition is treated strictly instead of making an approximation.The coupling equations,which are easy to numerical implementation,are derived from the equation of motion and the equation of continuity.Moreover,the validity of this model is illustrated with several numerical examples of different bottom parameters and the equation of energy conservation.It is shown that a boundary correction is introduced by the strict formulizing of the boundary condition in this model.This boundary correction guarantees the coupling coefficients being symmetrical and makes the sound fields satisfy the energy conservation.Thus,the energy-conserving coupled model is able to handle non-horizontal boundaries adequately,and the two-way sound fields in a non-horizontal stratified media can be calculated exactly by this model. | MO Yaxiao PIAO Shengchun ZHANG Haigang LI Li | 2016 | Chinese Journal of Acoustics2016，35，2： | 5 |

| 4 | Pipe-assembly approach for ships using modified NSGA-Ⅱ algorithm显示文摘Pipe-routing for ship is formulated as searching for the near-optimal pipe paths while meeting certain objectives in an environment scattered with obstacles. Due to the complex construction in layout space, the great number of pipelines, numerous and diverse design constraints and large amount of obstacles, finding the optimum route of ship pipes is a complicated and time-consuming process. A modified NSGA-Ⅱ algorithm based approach is proposed to find the near-optimal solution to solve the problem. By simplified equipment models, the layout space is firstly divided into three dimensional(3D) grids to build its mathematical model. In the modified NSGA-Ⅱ algorithm, the concept of auxiliary point is introduced to improve the search range of maze algorithm(MA) as well as to guarantee the diversity of chromosomes in initial population. Then the fix-length coding mechanism is proposed, Fuzzy set theory is also adopted to select the optimal solution in Pareto solutions. Finally, the effectiveness and efficiency of the proposed approach is demonstrated by the contrast test and simulation. The merit of the proposed algorithm lies in that it can provide more appropriate solutions for the designers while subject certain constrains. | Sui Haiteng Niu Wentie Niu Yaxiao Zhou Chongkai Gao Weigao | 2016 | Computer Aided Drafting,Design and Manufacturing2016，26，2： | 2 |
| 5 | Integration of two-dimensional morphology and porous surfaces to boost methanol electrooxidation performances of PtAg alloy nanomaterials显示文摘As an attempt to minimize the usage amounts of noble metals in catalysis,PtAg alloy nanocrystals with a porous nanosheet morphology were fabricated through a galvanic replacement reaction.During the reaction,ascorbic acid was added to the solution to protect the Ag triangular nanoplates from being totally etched. Structural characterizations indicated that the obtained nanocrystals had thin porous basal planes and winding edges with abundant bulges.Such unique two-dimensional porous architectures endowed this nanomaterial with plenty of catalytically active sites and structural benefits in electron and mass moving, as well as morphology stability.Electrochemical tests proved that the PtAg porous nanosheets had superior catalytic activity and durability towards methanol electrooxidation in basic media.Specifically,the mass and specificactivities of the PtAg porous nanosheets were 4.5and 2.7times higher than those of a commercial Pt/C catalyst.In addition to the special structures,the introduction of Ag enhanced the catalytic performances of the PtAg porous nanosheets. | Changshuai Shang Yaxiao Guo Erkang Wang | 2018 | Nano Research2018，11，12： | 2 |
| 6 | Estimation of transpiration coefficient and aboveground biomass in maize using time-series UAV multispectral imagery显示文摘Estimating spatial variation in crop transpiration coefficients(CTc) and aboveground biomass(AGB)rapidly and accurately by remote sensing can facilitate precision irrigation management in semiarid regions. This study developed and assessed a novel machine learning(ML) method for estimating CTc and AGB using time-series unmanned aerial vehicle(UAV)-based multispectral vegetation indices(VIs)of maize under several irrigation treatments at the field scale. Four ML regression methods: multiple linear regression(MLR), support vector regression(SVR), random forest regression(RFR), and adaptive boosting regression(ABR), were used to address the complex relationship between CTcand VIs. AGB was then estimated using exponential, logistic, sigmoid, and linear equations because of their clear mathematical formulations based on the optimal CTcestimation model. The UAV VIs-derived CTcusing the RFR estimation model yielded the highest accuracy(R^(2)= 0.91, RMSE = 0.0526, and n RMSE = 9.07%). The normalized difference red-edge index, transformed chlorophyll absorption in reflectance index, and simple ratio contributed significantly to the RFR-based CTcmodel. The accuracy of AGB estimation using nonlinear methods was higher than that using the linear method. The exponential method yielded the highest accuracy(R^(2)= 0.76, RMSE = 282.8 g m, and n RMSE = 39.24%) in both the 2018 and 2019 growing seasons. The study confirms that AGB estimation models based on cumulative CTcperformed well under several irrigation treatments using high-resolution time-series UAV multispectral VIs and can support irrigation management with high spatial precision at a field scale. | Guomin Shao Wenting Han Huihui Zhang Yi Wang Liyuan Zhang Yaxiao Niu Yu Zhang Pei Cao | 2022 | The Crop Journal2022，10，5： | 2 |

| 13 | A coupled-mode sound propagation model with complex effective depth显示文摘A coupled-mode sound propagation model with complex effective depth is presented,in order to involve the effect of branch line integral for acoustic field in a range-dependent waveguide.The equations of motion and continuity are used to obtain the coupled equations,which satisfy boundary conditions in the waveguide with varying topography and contain one coupling matrix.Meanwhile,the couplings between discrete and continuous spectrum are dealt with based on complex effective depth theory.Numerical simulations show that the accuracy of transmission loss is improved by the coupled mode model when eigenvalues of trapped modes are located near the branch point.The acoustic field in a non-horizontally stratified waveguide can be calculated efficiently and accurately by this model,and the energy corresponding to trapped modes,leaky modes and branch line integral can be considered adequately. | MO Yaxiao PIAO Shengchun ZHANG Haigang LI Li | 2014 | Chinese Journal of Acoustics2014，33，4： | 0 |

| 15 | On the accurate characterization of quantum-dot light-emitting diodes for display applications显示文摘Quantum dot light-emitting diodes(QLEDs)are a class of high-performance solution-processed electroluminescent(EL)devices highly attractive for next-generation display applications.Despite the encouraging advances in the mechanism investigation,material chemistry,and device engineering of QLEDs,the lack of standard protocols for the characterization of QLEDs may cause inaccurate measurements of device parameters and invalid comparison of different devices.Here,we report a comprehensive study on the characterizations of QLEDs using various methods.We show that the emission non-uniformity across the active area,nonLambertian angular distributions of EL intensity,and discrepancies in the adopted spectral luminous efficiency functions could introduce significant errors in the device efficiency.Larger errors in the operational-lifetime measurements may arise from the inaccurate determination of the initial luminance and inconsistent methods for analyzing the luminance-decay curves.Finally,we suggest a set of recommended practices and a checklist for device characterizations,aiming to help the researchers in the QLED field to achieve accurate and reliable measurements. | Wangxiao Jin Yunzhou Deng Bingbing Guo Yaxiao Lian Baodan Zhao Dawei Di Xiaowei Sun Kai Wang Shuming Chen Yixing Yang Weiran Cao Song Chen Wenyu Ji Xuyong Yang Yuan Gao Shuangpeng Wang Huaibin Shen Jialong Zhao Lei Qian Fushan Li Yizheng Jin | 2022 | npj Flexible Electronics2022，6，1： | 0 |
| 16 | Transient axonal glycoprotein-1 induces apoptosisrelated gene expression without triggering apoptosis in U251 glioma cells显示文摘Previous studies show that transient axonal glycoprotein-1, a ligand of amyloid precursor protein, increases the secretion of amyloid precursor protein intracellular domain and is involved in apoptosis in Alzheimer's disease. In this study, we examined the effects of transient axonal glycoprotein-1 on U251 glioma cells. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay showed that transient axonal glycoprotein-1 did not inhibit the proliferation of U251 cells, but promoted cell viability. The terminal deoxynucleotidyl transferase dUTP nick end labeling assay showed that transient axonal glycoprotein-1 did not induce U251 cell apoptosis. Real-time PCR revealed that transient axonal glycoprotein-1 substantially upregulated levels of amyloid precursor protein intracellular C-terminal domain, and p53 and epidermal growth factor receptor mRNA expression. Thus, transient axonal glycoprotein-1 increased apoptosis-related gene expression in U251 cells without inducing apoptosis. Instead, transient axonal glycoprotein-1 promoted the proliferation of these glioma cells. | Haigang Chang Shanshan Song Zhongcan Chen Yaxiao Wang Lujun Yang Mouxuan Du Yiquan Ke Ruxiang Xu Baozhe Jin Xiaodan Jiang | 2014 | Neural Regeneration Research2014，9，5： | 0 |
