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...

A Posteriori Error Analysis of a Mixed FEM for the Coupled Brinkman-Forchheimer/Darcy Problem

We consider a mixed variational formulation recently proposed for the coupling of the Brinkman-Forchheimer and Darcy equations and develop the first reliable and efficient residual-based a posteriori error estimator for the 2D version of the associated conforming mixed finite ele...

The Role of Emotion on Autobiographical Memory in a Second Language: A Systematic Narrative Review

Aims and Objectives: This systematic narrative review synthesises 13 peer-reviewed studies examining how emotional valence and intensity influence autobiographical memory retrieval in a second language (L2) versus the first language (L1). It investigates how the language of retri...

CIF-MEREC: A Novel Algorithm Integrating Circular Intuitionistic Fuzzy Sets and MEREC for Multi-Criteria Decision-Making

Multi-criteria decision-making (MCDM) under collective expert uncertainty requires methodscapable of capturing both individual concordance and inter-evaluator disagreementwhile deriving objective criterion weights from the data. Existing Circular IntuitionisticFuzzy (CIF) approac...

Effects of traditional and cluster resistance training using four multi-joint exercises on neuromuscular performance in striking combat sport athletes

Abstract Background This randomized 6-week intervention study compared the effects of traditional and cluster resistance training on neuromuscular performance in non-professional striking combat sport athletes. Methods Twenty-four participants were allocated to a traditional trai...

Environmental Impact Shaping a Firm's Zero Leverage Decision: Analysing Debt Demand and Supply Determinants

ABSTRACT Zero‐leverage firms remain a puzzle in corporate finance. We propose a supply‐side mechanism linking environmental impact to debt access. Because creditors favour firms with high negative externalities and strong cash flows, environmentally friendly firms with high initi...

Maxwell kinematical algebras and 3D gravities

Abstract In this paper, we present a Maxwell extension of kinematical Lie algebras by promoting the contraction method underlying the Bacry and Lévy-Leblond cube to a semigroup expansion framework. Within this approach, we show that both non- and ultra-relativistic Maxwell algebr...

Association between fluid balance, muscle strength, and muscle quality in critically ill patients: a retrospective observational study

Abstract Background Intensive Care Unit–acquired weakness (ICUAW) is a frequent complication that significantly impairs functional recovery in critically ill patients. Fluid overload during critical illness has been associated with adverse outcomes, but its relationship with peri...

Team learning: the role of facilitation in Debriefing

Purpose This study aims to examine how facilitation influences high-quality debriefings as a vehicle for team learning and reflexivity in organizational contexts. Design/methodology/approach We employed an interpretive qualitative design with 23 work teams (n = 112) from diverse...

Effects of Zinc Supplementation on Glycemic Control, Insulin Resistance, Inflammation and Oxidative Stress in Diabetes: A Systematic Review and Meta‐Analysis of Randomized Controlled Trials

ABSTRACT Objectives Diabetes mellitus (DM) is a chronic metabolic disorder characterized by insulin resistance, impaired insulin secretion, and increased cardiometabolic and inflammatory burden. Zinc plays a key biological role in insulin synthesis, storage, signalling and antiox...

Inspection-Oriented Predictive Quality Modeling for MDF Manufacturing Using Industrial Process Data and Machine Learning

Continuous medium-density fiberboard (MDF) production presents a persistent quality-assurance problem: destructive laboratory tests return results too late to prevent off-specification material from accumulating before a corrective response is possible. This study develops an ins...
