在我国新一轮基础教育课程改革中,跨学科主题学习因其有利于突破学科边界解决复杂问题备受瞩目,成为未来数字人才培养的重要途径。如何“跨”?“跨”到什么程度?这成为当前一线课程与教学直面的新挑战。为了厘清跨学科主题学习设计的逻辑理路,适当借鉴发达国家跨学科课程与教学的有益经验,研究分析了加拿大教育强省安大略省于2022年发布的科学与技术课程标准文本。通过文本分析发现,安大略省高度重视STEM跨学科主线在课程架构中的统领作用,把跨学科大概念理解作为课程与教学的内在机理,并采用跨学科和融合学习两种形式开展教学。汲取其启示,跨学科主题学习首先要理解跨学科意蕴,聚焦核心素养育人目标,其次,探索出适合我国国情的跨学科主题学习设计理路,包括:立足本体学科提取学科大概念,形成“学科大概念群”;聚合学科学习与真实生活,形成“跨学科主题群”;设计“问题链—任务簇—证据集”,在问题解决中实现跨学科融合。

为了实现前沿压电催化水污染控制技术、大型仪器分析技术与实践操作能力培养的有机结合,设计了一个综合水污染控制工程实验——BaTiO_(3)优化制备及压电催化性能分析。通过对BaTiO_(3)进行不同时间的热处理,有效优化BaTiO_(3)压电催化降解染料性能。利用电子顺磁共振波谱仪(ESR)分析降解过程中自由基的生成,并借助猝灭实验明确不同自由基在染料降解过程中的作用。结果表明,对BaTiO_(3)进行2 h热处理可有效提高其压电催化降解罗丹明B(RhB)染料的性能。ESR检测分析反应体系能产生羟基自由基、单线态氧和超氧自由基,而猝灭实验结果表明羟基自由基在染料降解过程中起主导作用。

Iron is indispensable for the viablility of nearly all living organisms, and it is imperative for cells, tissues, and organisms to acquire this essential metal sufficiently and maintain its metabolic stability for survival. Disruption of iron homeostasis can lead to the development of various diseases. There is a robust connection between iron metabolism and infection, immunity, inflammation, and aging, suggesting that disorders in iron metabolism may contribute to the pathogenesis of arthritis. Numerous studies have focused on the significant role of iron metabolism in the development of arthritis and its potential for targeted drug therapy. Targeting iron metabolism offers a promising approach for individualized treatment of arthritis. Therefore, this review aimed to investigate the mechanisms by which the body maintains iron metabolism and the impacts of iron and iron metabolism disorders on arthritis. Furthermore, this review aimed to identify potential therapeutic targets and active substances related to iron metabolism, which could provide promising research directions in this field.

人的生命权利伴随着现代性的发展逐渐被凸显,而作为现代性发展的时代产物,生命政治学表现出对人作为现代主体的自然生命权利的价值审思。在此意义上,科威尔立足于生态中心主义的价值观将人置于整个生态系统的集合中,其生态社会主义理论无论对生态危机的揭示,还是对作为危机根源的资本逻辑的批判,都表现出对人的生命权利的政治关怀,具有丰富的生命政治意蕴。科威尔不仅从理论维度揭露了资本与危机对人的生命世界的渗入以及“资本力场”对人的生命权利的异化,而且从实践维度提出了资本主义视域下人的生命政治回归的基本构想,即通向生态社会主义社会以实现对人的生命权利的本质占有。因此,科威尔生态社会主义理论以资本逻辑批判与生命逻辑建构为主题,蕴含着以批判“资本力场”对人的生命权利异化为核心,以克服生命权利异化从而实现人的生命解放为应然旨归的生命政治逻辑。

Medicinal and dietary plants provide numerous nutritional and functional compounds and also have various potential health benefits to humanity. The specific and efficient techniques for accurate identification of nutritional compounds and functional metabolites is crucial for the development of functional foods from medicinal and dietary plants. Nuclear magnetic resonance (NMR) and mass spectrometry (MS) are indispensable and essential technologies that provide an unsurpassed wealth of untargeted identification， quantitative and qualitative analysis， and structural information in the study of food and plant products. In the past decade， the rapid development of modern analytical technology has led to the emergence of new approaches and strategies for natural products discovery. Especially the application of novel NMR- and MS-based identification and dereplication strategies aided by artificial intelligence and machine learning algorithms have brought about a significant shift in the natural products discovery process. These developments and changes in the natural products filed have given us insights into how to accurately target and mining nutritional， functional， and bioactive compounds. Thus， we have summarized recent research on novel NMR and MS based strategies and methods focusing on functional compounds， accurate identification and efficient discovery mainly in medicinal and dietary plants. This review could provide a comprehensive perspective for a better understanding of novel strategies and methods based on NMR and MS technologies， which could provide valuable insights and ideas for functional compounds mining.

为解决针对RRT*算法的搜索效率低下,冗余点过多,路径代价等问题,提出一种改进型RRT*算法。改进步长确定机制,通过全局自适应取代人工设置固定步长;采用分区采样点拒绝策略,通过减少重复地区的采样,减少搜索树冗余节点,提高搜索效率。对规划路径进行路径优化,减少路径代价与路径节点。通过设计两张障碍散乱与路径狭窄的地图与一张三维空间地图进行仿真实验,实验结果表明,改进型RRT*算法的搜索能力显著高于标准RRT*,对于环境有良好的鲁棒性与适应性。
