Shunting operation is the core link of railway station transportation organization, whose efficiency directly determines the turnover speed of trains, the utilization rate of station facilities and the overall operational efficiency of the railway network. With the rapid growth of rail freight and passenger transport volume, the traditional shunting operation mode, which relies on manual experience and backward equipment, has been difficult to adapt to the demand of modern railway intelligent de...

Against the backdrop of frequent global supply chain disruptions, intensifying geopolitical games, and the global call for carbon neutrality, the China-Europe Railway Express (CER Express) has evolved from a “channel construction” stage to a critical period of quality improvement and efficiency optimization. As the core logistics carrier of the Belt and Road Initiative (BRI), it has become a key link in stabilizing Eurasian trade and enhancing supply chain resilience. Based on the analysis frame...

Background: Managing teeth with open apices, particularly after trauma, failed root canal treatment and the presence of apical periodontitis, poses significant clinical challenges. Apexification using Mineral Trioxide Aggregate (MTA) has emerged as a predictable technique. Case summary: A 23-year-old patient presented with persistent fistula between the central and the lateral incisor, previously treated and associated with a resorbed open apex and apical radiolucency. Non-surgical retreatment w...

In this work, we prove that the quintic energy critical wave inside a cylindrical convex domain$\Omega \subset {ℝ}^3$with smooth boundary$\partial \Omega \ne \varnothing$is well-posed in energy space. The dispersive estimates found in [1] and the St...

This study aims to explore the application path and practical effect of the deep integration of the BOPPPS teaching model and virtual simulation technology in the teaching of “Medical Imaging Examination Technology”. In response to the long-standing core pain points in the teaching of this course, such as expensive equipment, scarce practical opportunities, high risks, and the disconnection between theory and practice, a new teaching system is constructed with the BOPPPS six-stage teaching model...

Taking the attitudinal system in Martin’s Appraisal Theory as the analytical framework, this study takes news reports in The Economist’s dedicated China column from 2020 to 2025 as the research corpus. Adopting an integrated method of corpus-based quantitative annotation and critical discourse analysis, this paper examines the distribution patterns of attitudinal resources, discursive strategies, and the mechanism through which China’s national image is constructed. The findings show that the co...

This study examines Boris Johnson’s inaugural address delivered on 24 July 2019 through the lens of transitivity within the framework of Systemic Functional Grammar. Situated at a critical stage of the Brexit process, the speech provides an analytically significant case for exploring how linguistic resources construct political authority during institutional transition. By combining quantitative analysis of process-type distribution with qualitative clause-level interpretation, this study identi...

Stimulant utilization is increasing among university students globally due to pressure to improve their academic performance. The current work looks at the link between stimulant knowledge, attitudes toward use and academic pressure among undergraduates at the University of Energy and Natural Resources (UENR). The study adopted two psychological theories, Planned Behaviour and Strain, and employed the cross-sectional questionnaire for data collection. Data were obtained from 234 undergraduates a...

This study investigates how VR technology transforms the translation of culture-loaded terms from linguistic conversion to multimodal meaning production. Using the “Qi Culture VR Museum” as a case study, we demonstrate that VR enables an active process of meaning reconstruction through “perceptual construction” and “context generation.” By integrating multimodal analysis with critical theory, this research develops an “immersive translation” model to analyze how concepts like “Jixia Academy” are...

This study aimed to investigate the lipid-lowering effect of Red Glutinous Sorghum (RGS) in high-fat diet-induced obese mice. Mice were randomly divided into a normal control group (NC, n = 6, normal diet) and a high-fat diet group (HFD, n = 12, high-fat diet) and fed for 9 weeks to establish an obesity model. After successful model establishment, the HFD-fed mice were randomly reassigned to either the HFD group (n = 6, high-fat diet) or the RGS group (n = 6, RGS-diet) for a 7-week intervention ...
