Self-Perceived Knowledge, Self-Efficacy, and Reported Integration of Generative Artificial Intelligence Among University Faculty: An Exploratory Profile Analysis

Generative artificial intelligence (GAI) adoption in higher education raises questions about the relationships among perceived knowledge, confidence, attitudes, and reported teaching practices. A cross-sectional study of 149 faculty members at an Ecuadorian public university exam...

Habitat Risk Assessment for the Tidal Marshes and Flats of Huildad Bay, Isla Grande de Chiloé, Chile

The tidal marsh and tidal flats in the intertidal zones of Chiloé, Chile are highly productive ecosystems that provide essential ecosystem services and preserve local biodiversity. However, they face increasing pressure from human activities. This study evaluated the cumulative r...

Association between muscle quality index and time to stand up from the prone position in community-dwelling older adults

Both muscle strength and muscle quality are essential factors for preserving autonomy and functionality in older adults (OA). However, the relationship between muscle quality index (MQI) and the time to stand up from the prone position (SPP) in this population is unknown. The pri...

Landmark-defined two-dimensional lung configuration in women with osteogenesis imperfecta type III: an exploratory geometric morphometric pilot study

Osteogenesis imperfecta (OI) type III is a rare disorder in which severe thoracic deformity may alter pulmonary anatomy. This exploratory pilot study assessed whether the relative two-dimensional configuration of four reproducible pulmonary landmarks differs between adult women w...

A review of autonomous and low cost sensor systems for surface water quality monitoring with implications for local decision making

Preserving water quality has become a critical priority due to the increasing pressure on water resources from population growth, production activities and climate change. This article reviews recent studies on water quality monitoring in lakes, rivers and reservoirs, with a focu...

Dietary Patterns, Micronutrient Adequacy, and Metabolic Vulnerability in Alzheimer’s Disease: A Critical Narrative Review

Dietary factors may influence cognitive aging and Alzheimer’s disease (AD), but observational associations, mechanistic findings, and intervention effects should not be considered equivalent evidence. This critical narrative review examines how dietary patterns, micronutrient ade...

Evolution of striking dominance in Ultimate Fighting Championship: A cross-temporal analysis of factors associated with victory

This study examined the evolution of action frequencies associated with victory in UFC bouts across three distinct eras (2003–2004, 2013–2014, and 2023–2024). A total of 1722 fights were analyzed: Early Era (2003–2004; n = 77), Transition Era (2013–2014; n = 813), and Modern Era...

Across the vast sweep of the Amazon Basin, thousands of rivers, streams and floodplain lakes flow in an immense, interconnected waterscape— home to an unparalleled diversity of freshwater fishes. More than 2,700 species have so far been recorded, with dozens more added each year...

Chile-ED-Resp: A Curated and Reproducible Weekly Hospital Dataset for Respiratory Emergency-Demand Forecasting in Chile

Respiratory emergencies create recurrent seasonal pressure on hospital services, yet reproducible forecasting research is often hindered by the effort required to retrieve, interpret, harmonize, and document public administrative data. Chile-ED-Resp is a curated secondary dataset...

E2(η6–Be6H6) (E = Si–Pb): Doubly Aromatic Inverse-Sandwich Complexes

Abstract We report E2(η6-Be6H6) (E═Si, Ge, Sn, Pb), a new family of doubly aromatic inverse sandwich clusters in which a tetrel diatomic is sandwiched between a beryllium hydride ring. All four members adopt a singlet D6h global minimum, separated from the nearest competing isome...
