无人机目标跟踪可应用于消防、军事等重要领域，已成为计算机视觉领域热门研究课题之一。现有的无人机目标跟踪算法大多基于传统RGB相机结合深度学习算法，但此类算法一方面无法避免无人机机体抖动造成的运动模糊，另一方面因传统RGB相机在低光照或过曝光场景下成像质量较差，难以跟踪目标，为此提出采用无人机搭载DAVIS事件相机的方法进行目标跟踪。设计了基于事件与灰度图的双模态融合跟踪网络，用Vicon运动捕捉系统制作了无人机视角下的目标跟踪Event-APS 28数据集，实现了在复杂光照场景下对目标物的有效跟踪。

距骨外侧突骨折（FLPT）在所有骨折类型中占比较低，容易漏诊或误诊。FLPT损伤机制多样，足部背屈、 内翻、外翻、外旋、轴向撞击等都可导致。FLPT 常用的分型方法包括 Hawkins 分型、McCrory-Bladin 分型、Boack 分 型、Tinner-Sommer分型以及最新的张英泽分型。临床上对FLPT的诊断首选X线检查，但由于足部副骨和骨赘较为 常见，在X线片上与其他骨折鉴别困难，因此常常需要进一步通过CT检查进行判断。FLPT的主要治疗方式包括石 膏外固定、闭合或切开复位内固定、骨块切除和关节融合等。大部分患者FLPT经治疗后预后良好，并且随着关节镜 技术日益成熟，患者预后优良率明显提升。 [ABSTRACT FROM AUTHOR]

Multi-spectral remote sensing technology can retrieve water quality parameters based on remote sensing band information, reduce monitoring costs, improve monitoring speed and quality, and provide a new way for large-scale water environment monitoring. Through analyzing the correlation of Sentinel-2 multi-spectral images and measured water quality data of the Xiaolangdi Reservoir on the Yellow River, an inversion model of water quality parameters in the best spectral band was established, and the remote sensing inversion of chemical oxygen demand（COD), total phosphorus（TP), total nitrogen（TN） and ammonia nitrogen（NH3-N） of the Xiaolangdi Reservoir was carried out. The accuracy and stability of inversion models were verified and the spatial distribution of each water quality parameter was inverted. The results show that among the four water quality parameter inversion models, the precision and stability of COD model is the highest, followed by TP, TN and the lowest is NH3-N, the COD concentration at the outlet and some edges of the reservoir is relatively higher and the concentrations of TN, TP and NH3-N in the center of the reservoir are higher than those at the edges.

Reorganization processing is an important means to improve the structural performance of low-strength wood. This study focused on laminated veneer lumber (LVL) produced through the reorganization processing of poplar wood. Specifically, the transverse compressive properties of the full surface, local surface, and end-point local surface of LVL under high-humidity conditions were investigated from the aspects of stress mode, pressure-bearing direction, and reinforcement method. The results indicated that moisture treatment had a substantial influence on the transverse compressive performance of poplar-based LVL, with the full surface compression under wet conditions being 33% of that under dry conditions. Under similar environmental conditions, the transverse compression of LVL was primarily associated with its compression location and compression direction. During local surface compression, the pressure-bearing face received significant support from the surrounding wood fibers. Notably, the local surface compressive strength was the highest when the pressure-bearing face was parallel to the veneer layers. Under dry conditions, the compressive strength of the local surface was 1.2 times that of the end-point local surface and 1.4 times that of the full surface. The compression differed notably with varying compression directions. When the pressure-bearing face was perpendicular to the veneer layer, the LVL was susceptible to early delamination or buckling failure. Under high-humidity conditions, the higher moisture content softened the LVL, but the strong support provided by self-tapping screws helped to reinforce its compression. In conclusion, the transverse compressive strength of poplar-based LVL exhibited sensitivity to environmental humidity. Therefore, in engineering applications, it is advisable to maintain a dry environment and ensure that the pressure-bearing face is parallel to the LVL. [ABSTRACT FROM AUTHOR]
