研发一种包含电加热和水冷却的快速热循环成型技术,以改善采用超临界氮气为物理发泡剂的注塑微孔发泡聚甲醛(POM)盖板的表面质量.通过优化设计,整个模具型腔表面的温度均匀性得到明显改善.定量研究模腔表面温度(T_M)对注塑微孔发泡POM盖板的泡孔结构和表面质量的影响,并分析相关的机理.结果表明,提高T_M可减小微孔发泡POM盖板的未发泡皮层厚度,但使其泡孔的直径少量增加、分布均匀性降低.使T_M从40提高至150℃可明显改善微孔发泡POM盖板的表面质量、减小表面粗糙度达85%,而不会明显增加成型周期.T_M取150℃时可消除常规注塑微孔发泡存在的制品表面缺陷.T_M要适当高(约130℃)以在改善微孔发泡POM盖板表面质量的同时保持良好的泡孔结构.

Autonomous robots have garnered extensive utilization in diverse fields. Among the critical concerns for autonomous systems, path planning holds paramount importance. Notwithstanding considerable efforts in its development over the years, path planning for autonomous systems continues to grapple with challenges related to low planning efficiency and inadequate obstacle avoidance response in a timely *** study proposes a novel and systematic solution to the path planning problem within intricate office buildings. The solution consists of a global planner and a local planner. To handle the global planning aspect, an adaptive clustering-based dynamic programming rapidly exploring random tree(ACDP-RRT) algorithm is proposed. ACDP-RRT effectively identifies obstacles on the map by leveraging geometric *** obstacles are then represented as a collection of sequentially arranged convex polygons, optimizing the sampling region and significantly enhancing sampling efficiency. For local planning, a network decoupling actor-critic(ND-AC) algorithm is employed. The proposed ND-AC simplifies the local planner design process by integrating planning and control loops into a neural network(NN) trained via an end-to-end model-free deep reinforcement learning(DRL) framework. Moreover, the adoption of network decoupling(ND) techniques leads to an improved obstacle avoidance success rate when compared to conventional actor-critic(AC)-based methods. Extensive simulations and experiments are conducted to demonstrate the effectiveness and robustness of the proposed approach.

Objective: Radix Bupleuri and Radix Paeoniae Alba are referred to as Chai-Hu and Bai-Shao, respectively, in Chinese. We used molecular docking and network pharmacological approaches to explore the active components of this Chinese herb combination which is commonly used for treating Alzheimer's disease(AD), the Chai-Hu and Bai-Shao pair(CBP). Materials and Methods: The active compounds and action targets of Chai-Hu and Bai-Shao were identified in the Traditional Chinese Medicine Systems Pharmacology database, and the Therapeutic Target Database, Drug Bank, Gen Cards, Dis Ge NET, and Online Mendelian Inheritance in Man databases were used to identify therapeutic targets in patients with AD. To identify a common target of CBP in the treatment of AD, we used the Metascape tool to perform Gene Ontology function enrichment and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses. In addition, CBP-AD protein–protein interaction(PPI) and herb-component-target networks were created using Cytoscape 3.8.2. Molecular docking was verified using Auto Dock tools. Results: We identified 20 active compounds of CBP, 202 active targets, 1,323 disease targets, and 117 active compound disease intersection targets;the PPI network showed that the top eight key targets were AKT1, interleukin(IL) 6, JUN, MAPK1, tumor necrosis factor, TP53, vascular endothelial growth factor, and epidermal growth factor. These act mainly on the fluid shear stress, atherosclerosis, IL-17, hypoxia-inducible factor-1, and nonalcoholic fatty liver disease pathways, among others, which control immune inflammation, cell proliferation, and apoptosis. Based on molecular docking results, the active components of CBP bind well to its key targets. Conclusion: Our results indicated that CBP was effective for treating AD by reducing the expression of inflammatory factors, promoting cell proliferation and differentiation, and preventing nerve cell death and anti-neuronal cell apoptosis.
