1Particulate flow modelling in a spiral separator by using the Eulerian multi-fluid VOF approach显示文摘The Euler-Euler model is less effective in capturing the free surface of flow film in the spiral separator,and thus a Eulerian multi-fluid volume of fluid(VOF)model was first proposed to describe the particulate flow in spiral separators.In order to improve the applicability of the model in the high solid concentration system,the Bagnold effect was incorporated into the modelling framework.The capability of the proposed model in terms of predicting the flow film shape in a LD9 spiral separator was evaluated via comparison with measured flow film thicknesses reported in literature.Results showed that sharp air–water and air-pulp interfaces can be obtained using the proposed model,and the shapes of the predicted flow films before and after particle addition were reasonably consistent with the observations reported in literature.Furthermore,the experimental and numerical simulation of the separation of quartz and hematite were performed in a laboratory-scale spiral separator.When the Bagnold lift force model was considered,predictions of the grade of iron and solid concentration by mass for different trough lengths were more consistent with experimental data.In the initial development stage,the quartz particles at the bottom of the flow layer were more possible to be lifted due to the Bagnold force.Thus,a better predicted vertical stratification between quartz and hematite particles was obtained,which provided favorable conditions for subsequent radial segregation.Lingguo Meng Shuling Gao Dezhou Wei Qiang Zhao Baoyu Cui Yanbai Shen Zhenguo Song 2023International Journal of Mining Science and Technology2023,33,2:2

3Edge preserving super-resolution infrared image reconstruction based on L1-and L2-norms显示文摘超级决定(SR ) 增加图象分辨率的一种广泛地使用的技术正在使用算法的方法。然而,保存本地边结构和视觉质量在红外线(红外) 因为他们的劣势, SR 图象正在质问例如详细的缺乏,差的对比,和模糊的边。传统、先进的方法维持量的措施,但是他们主要没能保存边和视觉质量。这份报纸基于高频率层特征建议一个算法。这个算法在重建过程集中于 IR 图象边质地。IR 图象的吝啬的坡度由建议算法重建了的试验性的结果表演分别地基于 L1 标准, L2 标准,和传统的混合标准比传统的算法的到 1.5, 1.4,和 1.2 次增加了。重建的图象的山峰 signal-to-noise 比率,结构的类似索引,和视觉效果也改善了。Shaosheng DAI Dezhou ZHANG Junjie CUI Xiaoxiao ZHANG Jinsong LIU 2017Frontiers of Optoelectronics2017,10,2:1
4Enhanced detection of ppb-level NO_(2)by uniform Pt-doped ZnSnO_(3)nanocubes显示文摘ZnSnO_(3) nanocubes(ZSNCs)with various Pt concentrations(i.e.,1 at%,2 at%,and 5 at%)were synthesized by a simple one-pot hydrothermal method.The microstructures of pure and Pt-doped ZSNCs were characterized by X-ray diffractometry,scanning electron microscopy,transmission electron microscopy,energy-dispersive X-ray spectroscopy,and X-ray photoelectron spectroscopy.Results showed that the pure ZSNCs have a perovskite structure with a side length of approximately 600 nm;this length was reduced to 400 nm after Pt doping.Following doping,PtO_(x)(PtO and PtO_(2)) nanoparticles with a diameter of approximately 5 nm were uniformly coated on the surface of the ZSNCs.Systematic investigation of the gas-sensing abilities of the nanocubes showed that the Pt-doped ZSNCs have excellent sensing properties toward nitrogen dioxide(NO_(2)) gas in the operating temperature range of 75-175℃.Among the sensors prepared,that based on 1 at%Pt-doped ZSNCs exhibited the best response of 16.0 toward 500 ppb NO_(2) at 125℃;this response is over 11 times higher compared with that of pure ZSNCs.The enhanced NO_(2) sensing mechanism of the Pt-doped ZSNCs may be attributed to the synergistic effects of catalytic activity and chemical sensitization by Pt doping.Yaoyu Yin Yanbai Shen Sikai Zhao Ang Li Rui Lu Cong Han Baoyu Cui Dezhou Wei 2022International Journal of Minerals,Metallurgy and Materials2022,29,6:0
5Study on infrared image super-resolution reconstruction based on an improved POCS algorithm显示文摘Aiming at the disadvantages of the traditional projection onto convex sets of blurry edges and lack of image details,this paper proposes an improved projection onto convex sets(POCS) method to enhance the quality of image super-resolution reconstruction(SRR).In traditional POCS method,bilinear interpolation easily blurs the image.In order to improve the initial estimation of high-resolution image(HRI) during reconstruction of POCS algorithm,the initial estimation of HRI is obtained through iterative curvature-based interpolation(ICBI) instead of bilinear interpolation.Compared with the traditional POCS algorithm,the experimental results in subjective evaluation and objective evaluation demonstrate the effectiveness of the proposed method.The visual effect is improved significantly and image detail information is preserved better.Shaosheng Dai Junjie Cui Dezhou Zhang Qin Liu Xiaoxiao Zhang 2017Journal of Semiconductors2017,38,4:0
6Mechanisms of autophagy function and regulation in plant growth,development,and response to abiotic stress显示文摘Autophagy is an evolutionarily conserved degradation pathway of lysosomes(in mammals)and vacuoles(in yeasts and plants)from lower yeasts to higher mammals.It wraps unwanted organelles and damaged proteins in a double-membrane structure to transport them to vacuoles for degradation and recycling.In plants,autophagy functions in adaptation to the environment and maintenance of growth and development.This review systematically describes the autophagy process,biological functions,and regulatory mechanisms occurring during plant growth and development and in response to abiotic stresses.It provides a basis for further theoretical research and guidance of agricultural production.Yongbo Li Xiangmin Xu Guang Qi Dezhou Cui Chen Huang Xinxia Sui Genying Li Qingqi Fan 2023The Crop Journal2023,11,6:0
