Despite the rapid progress in the study of planar Hall effect (PHE) in recent years, all the previous works only showed that the PHE is connected to local geometric quantities, such as Berry curvature. Here, for the first time, we point out that the PHE in magnetic Weyl semimetals is directly related to a global quantity, namely, the Chern number of the Weyl point. This leads to a remarkable consequence that the PHE observation predicted here is robust against many system details, including the Fermi energy. The main difference between non-magnetic and magnetic Weyl points is that the latter breaks time-reversal symmetry T , thus generally possessing an energy tilt. Via semiclassical Boltzmann theory, we investigate the PHE in generic magnetic Weyl models with energy tilt and arbitrary Chern number. We find that by aligning the magnetic and electric fields in the same direction, the trace of the PHE conductivity contributed by Berry curvature and orbital moment is proportional to the Chern number and the energy tilt of the Weyl points, resulting in a previously undiscovered quantized PHE plateau by varying the Fermi energy. We further confirm the existence of PHE plateaus in a more realistic lattice model without T symmetry. By proposing a new quantized physical quantity, our work not only provides a new tool for extracting the topological character of the Weyl points but also suggests that the interplay between topology and magnetism can give rise to intriguing physics.

Corrosion poses a major threat to the safety of transportation pipelines. Therefore, it is crucial to have an in-depth understanding of corrosion mechanisms in pipeline steels for the effective management of pipeline integrity. Conducting research on corrosion mechanisms relies on the use of efficient and reliable corrosion monitoring and analysis techniques. The advancements in corrosion monitoring techniques specifically designed for the localized corrosion monitoring were aimed to be introduced, and a comprehensive overview of recent progress in understanding the localized corrosion mechanisms in pipeline steels was provided. Based on the different corrosive environments encountered, the localized corrosion issues inside pipelines are classified into two categories: localized corrosion primarily influenced by electrochemical processes and localized corrosion controlled by both electrochemical and mechanical factors. Additionally, a thorough analysis of the synergistic effects between micro-cell and macro-cell currents, as well as the interplay of mechanics and electrochemistry is presented. Finally, recommendations for future research on the mechanisms of internal localized corrosion in pipelines are provided.

背景:治疗后交叉韧带胫骨附着点撕脱骨折的最佳手术技术仍值得商榷。随着关节镜手术的应用与成熟,它在后交叉韧带胫骨附着点撕脱骨折的诊疗中有很大前景。目的:综述关节镜技术在后交叉韧带胫骨附着点撕脱骨折治疗中的应用与进展,包括不同关节镜治疗方法、手术入路、胫骨隧道设计、缝合材料选择以及内固定植入物选择等。方法:通过计算机对中国知网、PubMed、Web of Science及ScienceDirect等数据库中的相关文献进行检索,检索时间为2003年1月至2023年11月,中文检索词为“后交叉韧带,后十字韧带,撕脱骨折,关节镜”;英文检索词为“posterior cruciate ligament,avulsion,fracture,tibia,arthroscopic,operation,fixation,treatment”。共纳入97篇文献进行综述。结果与结论:关节镜技术提供了一种可靠的治疗方式来治疗后交叉韧带胫骨附着点撕脱骨折。根据入路、缝合材料类型以及用于缝合的入路和胫骨隧道数量等不同,关节镜技术可以分为关节镜下缝线固定结合自体移植物增强重建、关节镜下多交叉带缝合桥固定、关节镜下高强度缝线固定以及关节镜下直接前后缝合悬吊固定等几类。在各种研究中,常用的临床结果评估指标包括关节活动度、Lysholm评分、国际膝关节文献委员会评分及KT-2000关节测量仪差等,研究显示关节镜手术后末次随访时上述指标检测结果较术前显著改善,影像学随访结果显示关节镜手术都取得了令人满意的结果。在随访过程中,接受关节镜技术治疗后的各类交叉韧带胫骨附着点撕脱骨折患者都未出现严重并发症,例如创伤性关节炎、神经血管损伤、围手术期伤口感染、血栓形成以及骨折不愈合等。

基于2006—2022年A股上市公司样本,以《反垄断法》的实施作为准自然实验,运用双重差分模型考察了我国调整市场竞争关系的具体部门法规范实施对企业专利创新的影响。结果发现,相比竞争性企业,《反垄断法》的实施显著抑制了垄断性企业的专利创新活动,抑制效应通过降低企业研发费用进行传导,地区知识产权保护的增强可以显著削弱政策的抑制效应。进一步异质性分析结果表明,《反垄断法》的实施并不存在选择性执法现象,且对抑制国有企业创新激励有更显著的作用;《反垄断法》的实施在政府干预程度高的地区、高新技术产业抑制效果更强。研究发现丰富了反垄断规制对企业创新能力影响的相关研究,为政府干预中性提供了证据。

推动地方政府参与减贫合作是澜湄区域减贫的重要方式。面对制度环境的复杂和参与主体的多元,区域减贫合作需要增加治理的韧性,以提升贫困治理的效能。韧性治理所包含的地方转向和自下而上的理念,契合了地方政府在国际合作中地位逐渐凸显的时代特征和实践逻辑。以中国地方政府参与澜湄减贫合作为例,从“环境-主体”“地方-全球”和“结构-行为”维度对其逻辑机理进行分析,研究发现,现行澜湄多层权力结构为地方政府参与区域减贫提供了动力机制,但地方政府丰富的减贫经验没有进一步向制度转化,地方在对接区域结构方面也存在权力障碍和资源缺乏等问题。据此,应在提升地方政府自我学习和自我组织能力的基础上,促进其在区域多边体系中发挥政策创新和制度扩散的作用,并增强其资源能力。
