感动是一种由外部刺激引发的非自主性、即时产生的情感状态,通常由强烈的事件触发。感动体验包括寒战、流泪和内心温暖等一系列主观感受,背后可能涉及交感神经系统与副交感神经系统的交替激活。目前,研究者主要从公共共享关系的增强、依恋情感的作用以及核心价值观的凸显三个方面阐释感动的产生。未来研究可进一步探讨感动情感的生成机制,提供更直接的实证证据,并关注其文化差异及其在个人成长与社会治理中的应用。

Virtual simulation technology is of great importance for the teleoperation of lunar rovers during the exploration phase, as well as the design of locomotion systems, performance evaluation, and control strategy verification during the R&D phase. The currently used simulation methods for lunar rovers have several disadvantages such as poor fidelity for wheel-soil interaction mechanics, difficulty in simulating rough terrains, and high complexity making it difficult to realize mobility control in simulation systems. This paper presents an approach for the construction of a virtual simulation system that integrates the features of 3D modeling, wheel-soil interaction mechanics, dynamics analysis, mobility control, and visualization for lunar rovers. Wheel-soil interaction experiments are carried out to test the forces and moments acted on a lunar rover’s wheel by the soil with a vertical load of 80 N and slip ratios of 0, 0.03, 0.05, 0.1, 0.2, 0.3, 0.4, and 0.6. The experimental results are referenced in order to set the parameters’ values for the PAC2002 tire model of the ADAMS/Tire module. In addition, the rough lunar terrain is simulated with 3DS Max software after analyzing its characteristics, and a data-transfer program is developed with Matlab to simulate the 3D reappearance of a lunar environment in ADAMS. The 3D model of a lunar rover is developed by using Pro/E software and is then imported into ADAMS. Finally, a virtual simulation system for lunar rovers is developed. A path-following control strategy based on slip compensation for a six-wheeled lunar rover prototype is researched. The controller is implemented by using Matlab/Simulink to carry out joint simulations with ADAMS. The designed virtual lunar rover could follow the planned path on a rough terrain. This paper can also provide a reference scheme for virtual simulation and performance analysis of rovers moving on rough lunar terrains.

针对钢材表面缺陷尺度不一,现有检测算法多尺度特征处理能力较差、精度有待提高的问题,提出了一种面向钢材表面缺陷检测的改进型算法,命名为ADP-YOLOv8。首先,提出了一种自适应权重下采样(Adaptive weight downsampling)模块,其通过加权组合不同的下采样特征图,增强了模型对缺陷信息的关注;然后,通过改进特征提取网络中的C2F模块,加强从网络高层的可扩展感受野中提取特征;最后,引入可编程梯度信息(PGI)模块,通过其多级辅助信息组件逐步整合不同尺度的特征,有效提高了模型对不同尺度缺陷敏感性。所提出方法的平均精度为79.3%,相比基准模型提高了3.5%;检测速度为163.2frame/s。相比其他主流的目标检测算法,改进后的检测器在性能上更具优势,展示出了在检测精度、速度和模型体积方面的良好平衡。

For adaptation to ever-changing environments,plants have evolved elaborate metabolic systems coupled to a regulatory network for optimal growth and defense. Regulation of plant secondary metabolic pathways such as glucosinolates(GSLs) by defense phytohormones in response to different stresses and nutrient deficiency has been intensively investigated, while how growth-promoting hormone balances plant secondary and primary metabolism has been largely unexplored. Here, we found that growth-promoting hormone brassinosteroid(BR) inhibits GSLs accumulation while enhancing biosynthesis of primary sulfur metabolites, including cysteine(Cys) and glutathione(GSH) both in Arabidopsis and Brassica crops, fine-tuning secondary and primary sulfur metabolism to promote plant growth. Furthermore, we demonstrate that of BRASSINAZOLE RESISTANT 1(BZR1), the central component of BR signaling, exerts distinct transcriptional inhibition regulation on indolic and aliphatic GSL via direct MYB51 dependent repression of indolic GSL biosynthesis, while exerting partial MYB29 dependent repression of aliphatic GSL biosynthesis. Additionally, BZR1 directly activates the transcription of APR1 and APR2 which encodes rate-limiting enzyme adenosine 5′-phosphosulfate reductases in the primary sulfur metabolic *** summary, our findings indicate that BR inhibits the biosynthesis of GSLs to prioritize sulfur usage for primary metabolites under normal growth *** findings expand our understanding of BR promoting plant growth from a metabolism perspective.
