针对偏振光谱图像融合方法在地物混杂背景遥感探测中多尺度变换融合图像存在边缘轮廓细节模糊、对比度不佳的问题,提出一种基于非下采样轮廓波变换的稀疏表示与引导滤波器相结合的图像融合方法,以改善融合图像的质量和视觉效果。首先,该方法通过非下采样轮廓波变换对光谱图像和偏振图像进行多尺度多方向分解,进而将图像分解成不同子带内的特征信息。其次,低频子带采用稀疏表示融合,从而降低融合图像中物体对比度损失。此外,采用引导滤波器融合高频子带,以增强图像轮廓细节信息。最后,对低频与高频融合系数进行非下采样轮廓波逆变换,最终得出融合图像。分析表明融合图像对比度相对于原始光谱图像与偏振度图像分别提升了54.5%和15.4%,更容易区分混杂背景下阴影中的物体。基于此方法对偏振光谱成像仪所采集的不同波长下的光谱与偏振图像进行融合,并实现真彩还原。真彩还原图像证明此融合方法在保留混杂背景下的环境信息的同时实现了物体和背景的有效区分,有效提高了偏振光谱遥感探测成像的图像质量,有助于提升偏振光谱遥感探测成像中图像信息的完整性和真实性,扩大其在复杂环境遥感探测和图像识别中的应用范围。

The dispersion relation and electromagnetic polarization of the plasma waves are comprehensively studied in cold electron, proton, and heavy charged particle plasmas. Three modes are classified as the fast, intermediate, and slow mode waves according to different phase velocities. When plasmas contain positively-charged particles, the fast and intermediate modes can interact at the small propagating angles, whereas the two modes are separate at the large propagating angles. The near-parallel intermediate and slow waves experience the linear polarization, circular polarization, and linear polarization again, with the increasing wave number. The wave number regime corresponding to the above circular polarization shrinks as the propagating angle increases. Moreover, the fast and intermediate modes cause the reverse change of the electromagnetic polarization at the special wave number. While the heavy particles carry the negative charges, the dispersion relations of the fast and intermediate modes are always separate, being independent of the propagating angles. furthermore, this study gives new expressions of the three resonance frequencies corresponding to the highly-oblique propagation waves in the general three-component plasmas, and shows the dependence of the resonance frequencies on the propagating angle, the concentration of the heavy particle, and the mass ratio among different kinds of particles.

Owing to their exceptional properties, high-entropy alloys(HEAs) and high-entropy materials have emerged as promising research areas and shown diverse applications. Here,the recent advances in the field are comprehensively reviewed,organized into five sections. The first section introduces the background of HEAs, covering their definition, significance,application prospects, basic properties, design principles, and microstructure. The subsequent section focuses on cutting-edge high-entropy structural materials, highlighting developments such as nanostructured alloys, grain boundary engineering,eutectic systems, cryogenic alloys, thin films, micro-nano-lattice structures, additive manufacturing, high entropy metallic glasses, nano-precipitate strengthened alloys, composition modulation, alloy fibers, and refractory systems. In the following section, the emphasis shifts to functional materials, exploring HEAs as catalysts, magneto-caloric materials, corrosion-resistant alloys, radiation-resistant alloys, hydrogen storage systems, and materials for biomedicine. Additionally, the review encompasses functional high-entropy materials outside the realm of alloys, including thermoelectric, quantum dots, nanooxide catalysts, energy storage materials, negative thermal expansion ceramics,and high-entropy wave absorption materials. The paper concludes with an outlook, discussing future directions and potential growth areas in the field. Through this comprehensive review,researchers, engineers, and scientists may gain valuable insights into the recent progress and opportunities for further exploration in the exciting domains of high-entropy alloys and functional materials.

成员各美其美,美人之美,美美与共,社会方能天下大同,但现实中成员各美其美易,而美人之美以及美美与共难,因而严重制约社会与组织的良性发展。难以美人之美与美美与共对成员后果如何、原因何在、怎样化解以及约束如何等,日渐成为学界和业界亟待解决的问题。基于此,本研究旨在基于情感事件理论,探究多元包容型人力资源实践(DIHRP)通过工作场所人际资本化对员工趋避情绪影响的内在作用机制和边界条件。通过413对员工及其同事配对数据的实证研究发现:(1)DIHRP显著负向影响恶意嫉妒,而显著正向影响积极共情;(2)工作场所人际资本化在DIHRP与恶意嫉妒和积极共情之间有显著中介作用;(3)多元构成调节DIHRP对工作场所人际资本化的正向影响,多元构成程度越高,DIHRP对工作场所人际资本化的正向影响越强;(4)任务依赖性不仅调节工作场所人际资本化对恶意嫉妒和积极共情的影响,还进一步调节DIHRP通过工作场所人际资本化对恶意嫉妒和积极共情的间接作用,即在任务依赖性程度越高,工作场所人际资本化对恶意嫉妒和积极共情的影响越强,DIHRP通过工作场所人际资本化对恶意嫉妒和积极共情的间接作用越强。

智能电网的建设思路决定了远郊变电站异常入侵监测的无人化趋势,促进了变电站异常入侵智能检测方法的快速发展。现阶段尚未拥有该场景下异常入侵目标数据集,且现有的目标检测方法也未针对变电站边缘计算端进行轻量化优化设计,不适用于需要全天候实时监测的变电站边缘设备。针对上述问题,从实际应用需求出发,构建变电站异常入侵目标数据集(Dataset for Anomaly Invasion Targets in Substations,SAITD),基于YOLOv5s模型提出适用于变电站边缘检测设备的轻量化异常入侵目标检测网络YOLOv5-Substation。添加微小尺度目标特征提取层与上采样轻量化算子CARAFE,在扩大感受野的同时,充分保留特征图中多尺度目标的语义信息,从架构端提高原有模型的检测精度。基于知识蒸馏模型,使用网络剪枝(Network-slimming)策略对原有模型进行轻量化改进,在保证原模型检测精度的同时,加速模型推理。仿真实验表明,轻量化后的边缘端计算模型精度相较于YOLOv5s提高了3.3%,推理速度提升了41.9%,可为智能电网的全速运行提供强有力的数据基础、技术支撑与安全保障。
