Language assessment literacy for CLIL: in-service teachers’ practices, perspectives, and (Re)learning needs

This study investigated Taiwanese in-service CLIL teachers’ understanding of language assessment concepts and identified their training needs in designing assessment in CLIL contexts. A total of 161 teachers participating in CLIL professional development programs were involved. D...

A Database-Centered Geospatial Infrastructure for Autonomous Vehicle Digital Twins: A Framework Integrating Semantic ODD Layers, Runtime Telemetry, and 3D Urban Context

Autonomous Vehicle (AV) Digital Twins require persistent geospatial infrastructures that connect semantic, spatial, temporal, environmental, road-reference, and 3D urban information across simulation and visualization. This study proposes a database-centered framework integrating...

Artificial Grain Boundaries Created by Freestanding Membrane Transfer Reveal Angle‐Dependent Ferroelectric Switching and Leakage in BaTiO 3

ABSTRACT Grain boundaries (GBs) strongly influence polycrystalline ferroelectrics, but their discrete effects are difficult to isolate because of nanoscale heterogeneity. Here, we use freestanding membrane transfer to fabricate artificial GBs with controlled, experimentally acces...

Understanding ongoing processes of terrestrial mud diapirism through absolute gravimetry and geodetic approaches in SW Taiwan: implications for geological hazards

Mud diapirs and mud volcanoes are widespread geological features driven by subsurface seepage or extrusion of liquid and over-pressured mudstone. These formations pose significant hazards due to the emission of flammable gases, formation of mudflows, and release of atmospheric me...

Cross-cultural measurement of social overload and social networking sites exhaustion: Rasch and DIF evidence from Ghana, Hong Kong, Türkiye

Social media research increasingly examines the psychological costs of constant connectivity, yet the cross-cultural comparability of widely used social overload and Social Networking Sites (SNS) exhaustion measures remains insufficiently tested. This study examined the dimension...

Preparing future nurses for person-centred mental health care through AI-assisted gamified learning: a mixed-methods study

Preparing nursing students to deliver person-centred mental health care requires not only psychiatric knowledge but also positive attitudes toward people with mental illness and the capacity for reflective thinking. This study evaluated an AI-assisted gamified mobile learning sys...

Engineering metal‐organic framework‐based smart porous nanoplatforms for targeted therapy and theranostic applications

Abstract Metal‐organic frameworks (MOFs) are materials that have recently emerged with the potential for various biomedical applications. Through engineering MOFs to contain various components and functionalities, they have progressed from porous materials to “smart” MOFs that ca...

Loneliness among community-dwelling older adults during the early stage of the Covid-19 pandemic in Taiwan: exploring community-level and individual-level predictors

Loneliness has arisen in policy agenda as a major societal challenge in many western countries. However, little empirical evidence has been provided on loneliness of community-dwelling older adults in Taiwan, a fast-ageing society in east Asia. This study aimed to describe the st...

Enhanced discrepancy-aware visual inspection with a single global threshold for industrial assembly

Automated optical inspection is widely used in industrial assembly, but collecting sufficient real defective samples and pixel-level annotations is difficult because critical faults such as missing components, loose fastening, and positional deviations are rare in production. Thi...

Enhanced resistive switching behavior in RF-sputtered Sm2Hf2O7 thin films through controlled process conditions

Sm 2 Hf 2 O 7 RRAM devices were developed via RF sputtering, and key factors including film thickness, thermal treatment, and post-metallization annealing were systematically evaluated in terms of their impact on switching characteristics. The pyrochlore structure of Sm 2 Hf 2 O...

Thermodegradation kinetics of hemicelluloses, cellulose, and lignin: A review of mechanistic interpretation and hybrid predictive frameworks

Understanding the thermodegradation kinetics of individual lignocellulosic components is essential for resolving inconsistencies in biomass decomposition modeling and improving predictive accuracy. This review aims to: (1) compare the kinetic models of different lignocellulosic c...

Chelating Agent-Mediated Pathways for PFOA Degradation and Defluorination in Fe3O4-Catalyzed H2O2 Reactions

Abstract Perfluorooctanoic acid (PFOA), a widely used per- and polyfluoroalkyl substance, is persistent in the environment and linked to health concerns, leading to strict regulations and the need for remediation strategies. This study explores PFOA degradation using magnetite (F...

Integrating SVR and STAR-BME for groundwater level forecasting and spatiotemporal mapping in the Choushui River alluvial fan, Taiwan

Abstract Groundwater is an essential water resource in the Choushui River alluvial fan, Taiwan, where intensive groundwater abstraction has caused severe land subsidence and groundwater management challenges. Accurate groundwater level forecasting and regional groundwater assessm...

Phototropic and skototropic growth in inorganic films

We report herein phototropic growth toward, and skototropic growth away from, an incoherent, unstructured, low-intensity light stimulus in the deposition of nonliving, inorganic material. Fundamental light–matter interactions yield growth of inorganic deposits with ordered mesost...

Associations between MoodSensing smartphone application use and psychiatric readmissions and emergency department visits among patients with bipolar disorder in Taiwan

Introduction This study examined the association between the frequency of MoodSensing smartphone application (MS app) use and psychiatric readmissions and emergency department visits among patients with bipolar disorder. Methods A 6-month prospective observational pilot study was...

Molecular Heptazine–Platinum Complexes to Model Metal–Support Coordination in Platinized Graphitic Carbon Nitride: Insights into Catalyst Stability and Support Suitability

Abstract Solid support materials are crucial in heterogeneous catalysis for stabilizing active metallic species. Among potential support materials, heptazine-based “graphitic carbon nitride” or “gC3N4” has received significant research attention due to its abundant nitrogen sites...

Arsenic-endemic regions correlate with elevated tumor mutational burden and genomic alterations in urothelial carcinoma

Purpose: Urothelial carcinoma includes upper tract urothelial carcinoma (UTUC) and urothelial carcinoma of the bladder (UCB). In Taiwan, the incidence of UTUC is disproportionately high. Environmental carcinogens such as arsenic may contribute to this pattern. This study aimed to...

MALT lymphoma mimicking IgG4-related disease

A 75-year-old man presented with left eye fullness, proptosis, and bilateral lacrimal gland enlargement with elevated serum IgG4 levels, initially suggesting IgG4-related disease. However, lacrimal gland biopsy revealed MALT lymphoma. This case highlights the overlapping clinical...

Annual geospatial foundation model embeddings for landslide susceptibility assessment in Taiwan

Landslide susceptibility models (LSMs) must identify unstable terrain before failure is visible, yet it remains unclear whether compact geospatial foundation-model embeddings encode such pre-event information. We evaluate the efficacy of annual 64-dimensional AlphaEarth Foundatio...
