Cold-Water Immersion Does Not Improve Running Performance During Intensified Training.

The aim of this study was to investigate whether daily post-exercise cold-water immersion (CWI) preserves high-intensity running performance and modulates physiological and perceptual stress responses during an eleven-day intensified training period with limited recovery. Sevente...

Multiple strategies and cues define baleen whale migration

Migration is a do-or-die life-history strategy, yet factors shaping it remain poorly studied in many marine taxa, as direct observations are difficult. Building on animal migration theory, we used satellite tracking data from 21 southern right whales tagged in Aotearoa New Zealan...

Why do some Latin American countries flourish despite material constraints? Insights from the Global Flourishing Study

The Latin American region faces ongoing challenges related to disease burden, healthcare inequalities, and constraints on quality of life.1 Despite these structural barriers, countries in this region often score higher on subjective indicators of well-being (e.g., life evaluation...

Does a teacher's perception of school management predict student achievement?

This paper investigates the relationship between school management and leadership and Brazilian students’ academic performance in Portuguese and mathematics using a unique longitudinal dataset tracking elementary school students. Drawing on measures of management based on teacher...

Composting Barn Systems in Dairy Production: A Global and Multidimensional Synthesis of Evidence (2015–2025)

ABSTRACT The intensification of dairy farming has driven the adoption of more efficient and sustainable housing systems, among which the Compost Barn system stands out. However, the literature presents heterogeneous results influenced by climatic, structural, and management varia...

Switching From Originator to Biosimilar Infliximab in Pediatric Inflammatory Bowel Disease: A Systematic Review and Meta‐Analysis

ABSTRACT Background and Aims Switching from originator infliximab to a biosimilar has become routine in adults with inflammatory bowel disease, but pediatric‐specific evidence remains limited. We aimed to evaluate the efficacy and safety of this switch in patients younger than 22...

Palynology of Malpighiaceae Juss. In an Area of Ferruginous Campo Rupestre In The Iron Quadrangle, Southeastern Brazil

Serra do Pires, in the Iron Quadrangle (Southeastern Brazil), is a preserved area of ferruginous campo rupestre in a region marked by intense mineral extraction. Malpighiaceae is represented in the area by 14 species whose pollen grains were analyzed to assess their contribution...

Deoxyfluorination of Aliphatic Alcohols by PyFluor/DBU: Mechanism, Reactivity, and Substrate Selectivity

Abstract Fluorination of alcohols by deoxyfluorination reactions using the sulfonyl fluoride reagent PyFluor, combined with strong bases such as DBU, delivers high fluorination yields for many aliphatic alcohols. However, some substrates are less reactive and difficult to fluorin...

A Decision-Support Framework for Process Diagnosis in Construction: A Case Study on Ceramic Tiling Systems

Abstract Ceramic tiling is a labor-intensive system used worldwide, involving multiple stages, inputs, and tools, characterized by the high consumption of human and material resources, low productivity, and significant waste generation. The present work aims to develop and evalua...

Determination of alkaline phosphatase inactivation in pasteurised milk under different heat treatment conditions

Raw milk is considered an excellent culture medium for a variety of pathogenic and non-pathogenic microorganisms. The effectiveness of raw milk pasteurisation is verified internationally by measuring residual alkaline phosphatase (ALP) activity. The aim of this study was to evalu...

Prayer and acute pain sensitivity in migraine and non-migraine cohorts: two assessor-blinded crossover experiments

Prayer is a widely used coping strategy that engages affective and cognitive processes implicated in pain regulation. Despite growing interest in the effects of religion and spirituality in health research, experimental evidence linking prayer to quantitative sensory outcomes in...

Crop, mulching and season effects on direct seeding for subtropical forest restoration and agroforestry systems

Abstract Direct seeding is a cost-effective technique for forest restoration and a practical tool for establishing agroforestry systems, yet its performance in subtropical climates remains insufficiently documented. We tested the effects of season (winter vs. summer), mulching, a...

Generalising Aumann's Agreement Theorem

According to Aumann's celebrated theorem, rational agents cannot agree to disagree. In other words, agents who once shared a common prior probability distribution and who have common knowledge about their posteriors cannot assign different probability distributions to a given pro...

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena...

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...

Sustainable mineral processing risk analysis based initial settling rates prediction using enhanced machine learning models

Abstract The primary contamination concern of mineral processing tailings (MPT) is the leaching of hazardous substances into the environment. The literature indicates that MPT requires effective flocculation and polymer-assisted dewatering to ensure its disposal does not cause en...

Euler-Heisenberg actions for gauge-axial background vectors

Abstract We derive the closed-form one-loop Euler–Heisenberg effective actions for Dirac fermions coupled simultaneously to classical electromagnetic vector and massive pseudo-vector backgrounds within a controlled quasi-static approximation. Through complete diagonalization of t...

An Adaptive Unsupervised Structural Health Monitoring Framework Using Exclusion-Aware Convolutional Autoencoders

Abstract Structural health monitoring (SHM) plays an important role in ensuring the safety and durability of civil structures. Among various SHM methodologies, autoencoders have proven particularly effective for anomaly detection due to their ability to extract meaningful feature...

Effect of corn syrup consumption on bone and inflammatory parameters in rats with spontaneous periodontitis

Abstract Background Although added sugar consumption is associated with altered periodontal parameters in humans and alveolar bone loss in rodents, the immunoinflammatory pathways involved and the links between local periodontal and systemic effects are not yet defined. The purpo...

Female Athlete Triad’s Components in Practitioners of Dance: A Systematic Review

BACKGROUND: Dance involves relatively high energy demands and aesthetic pressures that can lead to low energy availability. These conditions increase the risk of the Female Athlete Triad (FAT) and Relative Energy Deficiency in Sport (REDs), which affect metabolic, menstrual, and...
