Explore the lane change trajectory pattern driven by full-time domain trajectory data

引用

Journal of Traffic and Transportation Engineering(English Edition) 2024年

作者： Min Zhang Yuhan Nie Bo Wang Chi Zhang Yuming Zhou yijing Zhao School of Transportation Engineering， Chang'an University Engineering Research Center of Highway Infrastructure Digitalization， Ministry of Education School of Highway Chang'an University School of Civil and Environmental Engineering， Nanyang Technological University

Due to the increasing density and complexity of the highway network， a deep understanding of the characteristics of lane changing (LC) behavior is crucial for road refinement design. The emergence of full time domain trajectory big data provides unprecedented opportunities for in-depth research on highway safety geometry design. This article proposes a method framework for extracting LC trajectory patterns to explore the combination trajectory patterns during the LC process. This article achieves subdivision in driving mode detection by using the Adaptive Pruned Exact Linear Time (APELT) algorithm to detect change points， taking into account the short sequence features of LC. In order to achieve the classification of segmented fragments， we report a clustering technique based on similarity matching (SM)， which can effectively avoid the problem of excessive distortion in similarity measurement. The results indicate that APELT technology has certain advantages in F1 score and accuracy of LC pattern recognition， which is more in line with reality. The kappa score based on similarity matching is greater than 0.8， indicating high accuracy of pattern recognition. This study provides a novel data mining method for a comprehensive understanding of lane changing behavior under full time domain big data， which will provide reference for road design in complex scenes.

Hydrogen sulfide reduces oxidative stress in Huntington's disease via Nrf2

Neural Regeneration Research 2025年第6期20卷 1776-1788页

The pathophysiology of Huntington's disease involves high levels of the neurotoxin quinolinic acid. Quinolinic acid accumulation results in oxidative stress, which leads to neurotoxicity. However, the molecular and cellular mechanisms by which quinolinic acid contributes to Huntington's disease pathology remain unknown. In this study, we established in vitro and in vivo models of Huntington's disease by administering quinolinic acid to the PC12 neuronal cell line and the striatum of mice, respectively. We observed a decrease in the levels of hydrogen sulfide in both PC12 cells and mouse serum, which was accompanied by down-regulation of cystathionine β-synthase, an enzyme responsible for hydrogen sulfide production. However, treatment with NaHS(a hydrogen sulfide donor) increased hydrogen sulfide levels in the neurons and in mouse serum, as well as cystathionine β-synthase expression in the neurons and the mouse striatum, while also improving oxidative imbalance and mitochondrial dysfunction in PC12 cells and the mouse striatum. These beneficial effects correlated with upregulation of nuclear factor erythroid 2-related factor 2 expression. Finally, treatment with the nuclear factor erythroid 2-related factor 2inhibitor ML385 reversed the beneficial impact of exogenous hydrogen sulfide on quinolinic acid-induced oxidative stress. Taken together, our findings show that hydrogen sulfide reduces oxidative stress in Huntington's disease by activating nuclear factor erythroid 2-related factor 2,suggesting that hydrogen sulfide is a novel neuroprotective drug candidate for treating patients with Huntington's disease.

居民个人认定标准是国际税法与域外税法确立的一项重要税收管辖权规则。但各辖区实施不同标准容易引发重复征税问题,法律解释的差异更使跨境所得税收管辖权的征管形势日趋复杂。本文通过考察域外居民个人认定标准,对居民个人认定标准的制度肇源、演变与适用等问题进行分析,并从围绕“定居”概念修正住所标准、补充居住时间标准的辅助性测试、增加双重税收居民冲突协调程序等方面提出完善我国《个人所得税法》居民税收管辖权的具体建议。

爱尔兰作家保罗·林奇的2023年布克奖获奖小说《先知之歌》通过讲述主人公埃莉什一家从普通民众沦为难民的经历,反映出当下部分地区难民的真实遭遇和失序的政治局势。本文拟从小说内容与社会现实的结合中推演林奇的现实主义创作路径。林奇在爱尔兰历史中获取了真实的创作素材,并以都柏林为试验场,意图在都柏林的动荡中揭示个体生命在失序状态下的脆弱不安以及潜藏的恐怖主义因素。他以模拟、再现、超越现实的写作策略来观照难民的普遍境况,期待达成一种高度适配当下的现实主义,并以此引发“彻底共鸣”效果。但是,这种对难民以一概全式的再现仍然暴露出林奇在探索现实主义与当下现实的磨合方式时所产生的矛盾,这亦启示读者需以更为客观的视角看待难民危机。

岳麓秦简“家弗能入而环者”之“环”,不当释为“还债”,与债务追偿相关的文书或律令所见“环”和“环书”,应是指退还文书、校券及相关欠债凭证,引申含义则是拒绝履行来文申请。与文书退回相关的词汇有“环”和“却”,两者含义相近但绝不相同,各有其特定的使用场景和语汇内涵。通过对“环书”“却书”的分析,发现文书从发出到退回再复请是个动态生成的过程,文书的性质、构成和形态随着文书运作不断发生变化。秦代还通过律令对文书退回的原因、用语、退回文书的处理机制等方面进行规范,以此提高文书处理的效率,推动地方政务有序运转。

随着数字经济和实体经济深度融合,从企业数字化转型视角探究民生问题显得尤为重要。以2012—2019年中国A股上市公司为研究样本,通过文本分析识别企业数字化转型,验证了企业数字化转型对劳动力就业规模和薪酬水平的正向影响。但不同技能劳动力需求呈现结构性差异,非国有企业、生产效率较低以及融资约束较大的企业更有可能采用数字技术替代劳动,尤其是替代低技能劳动。研究结果揭示了企业数字化转型对劳动力就业的促进效应和替代效应,为推动经济高质量发展和“稳就业”目标实现提供政策启示。
