SAD-ReID: Semantically-anchored dynamics for unsupervised vehicle re-identification

<title>Abstract</title> Unsupervised vehicle re-identification (Re-ID) is pivotal for scalable intelligent transportation systems but faces significant challenges from severe noise accumulation. Traditional clustering-based methods often suffer from error propagation during onlin...

Copper/Iron-CocatalyzedSynthesis of FunctionalizedQuinazolines from gem -Difluoroalkenes and Amidines

Abstract A novel and efficient method for synthesizing functionalized acyl quinazolines has been developed via CuCl2·2H2O/FeBr3-cocatalyzed cascade cyclization of amidines with readily accessible gem-difluoroalkenes. The reaction proceeds in DMF under an air atmosphere, affording...

破解教育生产“黑箱”：学龄人口变化背景下义务教育资源配置效率的时空演化研究

学龄人口持续缩减与空间分布格局重塑，给义务教育资源配置效率提升带来严峻挑战。本文基于教育生产函数理论、新制度经济学与空间均衡理论，运用三阶段DEA模型与Malmquist生产率指数，测度2013—2022年中国31省域义务教育资源配置效率并分析其时空演化。研究发现：第一，剔除环境因素与随机干扰后，全国...

Evidence from Chinese Cities on the Effect of the COVID-19 Pandemic on the Resilience of Intercity Population Flow Networks

Abstract The rapidly spreading coronavirus disease 2019 (COVID-19) pandemic significantly affected population flows between cities and triggered a chain reaction within global urban networks. Using 366 Chinese cities as a case study, this study developed a dynamic and comprehensi...

An AHP-MAP Framework for Transparent and Evidence-Calibrated Evaluation of Technology-Transfer Performance in New R&D Institutions

Evaluating technology-transfer performance in new R&amp;D institutions requires an evaluation system that remains auditable while allowing empirical calibration with observed outcomes. This study proposes an AHP-MAP framework that combines the analytic hierarchy process with maxi...

Longitudinal Relation Between Childhood Maltreatment and Problematic Gaming in Early Adolescents: The Mediating Roles of Self-Control and Sex Differences

Childhood maltreatment has been linked to heightened risk for problematic gaming among adolescents, yet the self-regulatory processes underlying this association remain insufficiently understood. Drawing on the dual-mode model of self-control, the present three-wave longitudinal...

Exploring the coupling coordination of urban resilience and urban low-carbon in the Yellow River Basin

Against the backdrop of intensifying global climate change and increasingly prominent resource constraints, achieving synergies between resilience enhancement and low-carbon urban development has become a critical issue for advancing sustainable urban development. To address this...
