Temporal analysis of area and elevation changes in forest fires in İzmir Province (1995–2025)

The intensifying thermal and hydrological stress in the Mediterranean climate zone increases the spatial extent of forest fires and alters their topographic ascent dynamics. This study investigates the spatial acceleration and vertical elevation shifts of forest fires in İzmir Pr...

Baseline Liver Metabolic Health in Newly Diagnosed People Living with HIV Compared with HIV-Negative Controls: Cross-Sectional Findings from the Prospective MASHIV-TR Cohort

Metabolic dysfunction-associated steatotic liver disease (MASLD) is an important comorbidity in people living with HIV (PLWH), yet most data derive from individuals receiving antiretroviral therapy (ART). In the baseline cross-sectional analysis of the prospective multicentre MAS...

Trust in the Digital Home: Media Parenting Profiles, Digital Parental Awareness and Implications for Child and Family Social Work

ABSTRACT Digital transformations increasingly shape children's everyday lives, positioning parents as key mediators of digital risk, opportunity and trust within the family context. In early childhood, where children cannot independently regulate digital environments, parental me...

Physics-guided attention neural network for interpretable and robust photovoltaic fault classification with strict external validation

Accurate and interpretable fault diagnosis in photovoltaic (PV) systems is essential for improving operational reliability and reducing energy losses. This study proposes a Physics-Guided Attention Neural Network (PGANN) for three-class PV fault classification, including Open-cir...

Predicting BOD5 Removal Efficiency in a Constructed Wetland from Satellite and Meteorological Data Using Interpretable Machine Learning

Constructed wetlands (CWs) offer a low-cost and sustainable option for wastewater treatment, but their performance is commonly assessed through infrequent, periodic field sampling that yields temporally sparse records. This study evaluated whether five-day biochemical oxygen dema...

Buying With Envy or Buying with Control? The Role of Self-Control in Envious Purchase

In recent years’ phenomena such as social comparison changes consumers’ decisions and behaviors. Aligning with this notion, consumers who actively compare themselves with others might eventually feel envy. Envy is recognized as a negative emotion affecting purchase intention. In...

Artistic self-efficacy scale for middle school students: Development, validity, reliability, and measurement invariance evidence

This study developed an artistic self-efficacy scale for students in Grades 5–8 and examined its psychometric properties in visual arts education. A quantitative scale-development and validation design was used. Separate groups of experts and middle school students participated i...

Association between trabecular microarchitecture and impaction pattern in unilateral maxillary canines: CBCT-based fractal analysis

Alveolar bone characteristics have been suggested as potential contributors to maxillary canine impaction; however, the relationship between trabecular bone microarchitecture and impaction pattern remains unclear. This study aimed to compare alveolar trabecular microarchitecture...

Longitudinal Anti-HBs Monitoring and Seroprotection Patterns in Rituximab-Treated Patients with Pemphigus Vulgaris: A Retrospective Cohort Study

Rituximab induces prolonged B-cell depletion and may alter protective antibody levels, but longitudinal antibody to hepatitis B surface antigen (anti-HBs) patterns in pemphigus vulgaris remain poorly characterized. This study evaluated anti-HBs levels and seroprotection after rit...
