Instruments for Assessing Professional Reasoning in Occupational Therapy: A Systematic Review

Following PRISMA-COSMIN 2024 guidelines, this systematic review assessed the quality of evidence for quantitative instruments (OMIs) designed to measure professional reasoning in occupational therapy students and professionals between 2016 and 2025. Thirteen OMIs (~1,500 particip...

Origin of Pleistocene bonebeds at the GNL Quintero site (GNLQ1): New taphonomic evidence from a wetland mammal assemblage in the submerged landscapes of central Chile

The underwater bonebed of GNL Quintero 1 (GNLQ1) site located nearshore at Quintero Bay on the central coast of Chile (32° S), offers an unparalleled view of submerged Late Pleistocene environments in the South American Pacific continental shelf. By updating the site taphonomic h...

Can community energy become nuclear?

Community energy projects are typically associated with renewable, local, democratic and decentralised initiatives. The emergence of Small Modular Reactors and Microreactors challenges this historical gap between nuclear energy and energy communities by raising the possibility th...

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...

Emergence of pedagogical reasoning in Biology teachers upon observing a feedback practice in biodiversity

The study investigates the emergence of pedagogical reasoning among in-service Biology teachers as they observe a video-recorded feedback practice focused on biodiversity. Unlike cognitivist perspectives, we conceive pedagogical reasoning as a situated and relational process that...

Culture-Agnostic and Culture-Specific Analyses of Semantic Fluency in Korean and English Speakers With Alzheimer's Disease

PURPOSE: This study investigated cross-linguistic and cultural influences on semantic fluency in monolingual Korean- and English-speaking individuals with Alzheimer's disease (AD) by contrasting culture-agnostic and culture-specific analytic frameworks. We focused on how cultural...

Nonlocal Hamilton–Jacobi Equations on a network with Kirchhoff type conditions

In this article, we consider nonlocal Hamilton–Jacobi Equations on networks with Kirchhoff type conditions for the interior vertices and Dirichlet boundary conditions for the boundary ones: we provide general existence and comparison results in the case when the nonlocal operator...

Zinc Is Probably Not Accumulated as Zinc Sulfide, and Is Co-Released with Glutathione to the Culture Medium, in the Marine Alga Ulva compressa

The mechanisms involved in zinc (Zn) accumulation in response to a sulfur donor (NaHS) and a sulfur acceptor (hypotaurine) were analyzed in the marine alga Ulva compressa. The alga was cultivated with 10 μM of Zn, with 10 μM of Zn and increasing concentrations of NaHS for 0 to 7...

Functional Properties of Brosimum alicastrum Seed Flour Gels: Impact of Temperature, Concentration, and Additives on Rheology, Viscoelasticity, and Texture

Ramón seed flour (RSF), obtained from the drought- and hurricane-resistant Brosimum alicastrum, is a promising sustainable ingredient with high productivity and a favorable nutritional profile, but its functional properties remain poorly understood. This study characterized the r...

When does brand purpose stop creating brand equity? The moralizations trap of strategic self-sabotage

Purpose This study aims to conceptualize article challenges the assumption that brand purpose inherently strengthens brand equity. Drawing on hybrid logics theory, brand meaning theory and event system theory, the study examines the conditions under which brand purpose shifts fro...

Unimodular gravity with arbitrary diffusion function: a dynamical system reconstruction approach

Abstract We investigate cosmological diffusion models in unimodular gravity within a dynamical systems reconstruction framework. By treating the logarithmic slope of the diffusion sector as an invertible dynamical variable, the diffusion function can be systematically reconstruct...

Error Bounds for Physics Informed Neural Networks in Generalized KdV Equations Placed on Unbounded Domains

In this paper we study a rigorous setting for the numerical approximation via deep neural networks of the generalized Korteweg-de Vries (gKdV) model in one dimension, for subcritical and critical nonlinearities, and assuming that the domain is the unbounded real line. The fact th...

First report of Pantoea agglomerans causing Walnut Blight in Juglans regia L. in Chile

Walnut (Juglans regia L.) is Chile’s most cultivated nut tree, with 43,236 ha in 2024 and 62.8% of total tree nut export value (ODEPA, 2024). In summer 2024, symptoms were observed on walnut leaves and fruits in several Chilean regions: Metropolitana (Melipilla; 33°41´S, 71°12′W)...

An exact L2 criterion for periodic neutral equations with distributed delay

We establish a complete characterization of strong periodic solvability for linear neutral differential equations with distributed delay in Hilbert spaces. Our main result shows that strong well-posedness in the natural square-integrable setting is entirely determined by the inve...

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,...

Cellular stress leading to epithelial cell dysfunction in Sjögren’s syndrome

Cells are highly compartmentalized entities composed of membranous and nonmembranous structures, where organelles such as the endoplasmic reticulum (ER), Golgi apparatus, nucleus, mitochondria, lysosomes, peroxisomes, endosomes, and plasma membrane are organized. The plasma membr...

Late Holocene environmental dynamics and their influence on human occupation in the Santiago basin (33°S), Central Chile

Fluvial-alluvial deposits provide high-resolution records for reconstructing paleoenvironments and deciphering archaeological site-formation processes. Despite their prevalence in the Mediterranean-climate region of central Chile, a significant research gap persists in linking pr...

On Lp-spaces of functions with values in locally convex spaces

We study Lusin-measurable functions with values in locally convex spaces. In particular, the behavior of pointwise limits of sequences of Lusin-measurable functions and exhibit pathological phenomena arising in the nonmetrizable setting. Moreover, we establish approximation and d...

Attention-Based LSTM Forecasting of O3, NO2, and NO Concentrations in Eastern Santiago, Chile

In Santiago, Chile, the 8 h average atmospheric ozone (O3) concentration frequently exceeds the national air quality standard of 61 ppbv (parts per billion by volume). Due to local meteorological and topographic conditions, the highest ozone levels are observed at the Las Condes...

Modeling and numerical simulation of premixed combustion using the k−ɛ turbulence model

Combustion is a chemical process through which the chemical energy is converted into heat via exothermic reactions. Understanding and optimizing combustion phenomena is crucial for efficient energy conversion across a wide range of engineering applications. In recent decades, CFD...
