Network science in sports

Network science has become a central methodological framework for the study of complex systems, with applications across social, biological, and technological domains. Its strength lies in formalizing such systems as collections of interacting units, whose collective behavior dep...

Pedagogical Interventions That Support Self-Regulated Learning in Secondary School Students: A Systematic Literature Review

Self-regulation of learning (SRL) is a key skill for secondary school students, placing them as active and conscious agents of their own learning. It enables learners to plan, monitor, and evaluate their progress, fostering autonomy and responsibility. Teachers play a crucial rol...

Beyond Modified Transudates: Diagnostic Performance of the Feline Infectious Peritonitis Effusion Index on the Sysmex XN-1000V

The antemortem clinical and clinicopathological diagnosis of feline infectious peritonitis (FIP) remains challenging, particularly when effusions deviate from the classically protein-rich, low-to-moderate-cellularity phenotype. The FIP Effusion Index, defined as the ratio of delt...

The Canine Leishmaniosis Proteinogram: A Reference Serum Electrophoretic Atlas of 5544 Dogs over 18 Years

Serum protein capillary electrophoresis can characterise dysproteinaemia in dogs tested for canine leishmaniosis (CanL) as an integrated clinicopathological phenotype of humoral immune activation. This retrospective laboratory-based study evaluated serum protein electrophoretic p...

Endometrial Preparation for Frozen Embryo Transfer: Protocols and Pregnancy Outcomes.

Frozen embryo transfer (FET) has become widely used over the past decade, largely because of advances in vitrification techniques. To optimize pregnancy rates in FET cycles, accurate synchronization between embryo development and endometrial receptivity is essential. However, the...

Running Constraints Shape Multifractal Movement Complexity Beyond Physiological and Mechanical Load: A Pilot Study

Movement variability reflects adaptive neuromuscular reorganisation, but linear metrics alone cannot capture its temporal structure. This pilot study examined how running variations shape physiological and mechanical load responses using linear and nonlinear metrics. Fifteen recr...

Changes in Aerobic and Muscle-Strengthening Physical Activity and Self-Reported Morbidity Among University Students During the COVID-19 Pandemic: A Cross-Sectional Study

The COVID-19 pandemic substantially affected lifestyle behaviors among university students, potentially increasing their vulnerability to chronic noncommunicable diseases (NCDs). This cross-sectional study investigated associations between self-reported changes in the frequency o...

Characterization of Uniaxial Compressive Strength and Point Load Index and Their Correlation in Compact and Porous Building Stones: Insights from the Effects of Stone Heterogeneity

The point load index (PLI) is a low-cost and rapid test widely used for the indirect evaluation of uniaxial compressive strength (UCS). However, its accuracy in predicting UCS may differ between compact and porous stones. This study investigated the performance of the PLI for UCS...

Zoonotic Sarcocystis hominis and Sarcocystis heydorni in a Bovine Carcass: First Report in Portugal

During routine meat inspection, eosinophilic myositis-like lesions were detected in the masseter muscles of a 55-month-old bovine, leading to partial condemnation of the head. The lesions appeared as multiple round, yellowish-green areas, suggestive of a parasitic aetiology. Hist...

Runtime Firmware Update for 32-Bit Microcontrollers with Instruction Cache Under Concurrent Task Execution

Smart sensor devices increasingly require remote firmware updates to deploy new functionality, security patches and algorithmic improvements without interrupting services. Runtime firmware updates remain a significant challenge in embedded sensing systems, particularly in real-ti...

Transferability of Intra- and Inter-Sectoral Coordination Between Training Tasks and Official Matches in Semi-Professional Football Players

Background: This study examined training-to-match transferability of positional coordination in semi-professional football players, comparing responses between defensive and midfield/offensive positional sectors. Methods: Twenty-nine players were monitored during the 2023–2024 se...

Innovating from within: How does intrapreneurship influence the performance of public institution employees?

Purpose This study aims to analyze how intrapreneurship influences commitment to work, employee satisfaction, innovative behaviour and employee performance in public organizations. Design/methodology/approach To develop this study, a structured questionnaire was applied to a samp...

Movement of European freshwater mussels under simulated dewatering conditions

Freshwater ecosystems are exposed to altered hydrological regimes due to climate change and poor water management, resulting in frequent and intense dewatering events. Freshwater mussels (Unionida) are particularly vulnerable to rapid water-level declines. Dewatering can lead to...

An Initial Integration of Constructs That Account for Moral Actions: Moral Foundations, Values, and Character Strengths

Morality has been described as a psychological system comprising sets of values, practices, institutions, and psychological mechanisms that work together to support moral/socially positive behavior. Nonetheless, there have been relatively few efforts to integrate these diverse co...

Life Cycle Assessment of Anaerobic Digestion Pathways for Winery Residues: Influence of Functional Unit Selection on Wastewater Treatment and Grape Pomace Valorization

Winery activities generate large amounts of residues requiring sustainable management. Anaerobic digestion offers opportunities for resource recovery while reducing the environmental burdens associated with these residues. This study presents a gate-to-gate Life Cycle Assessment...

Negative Life Events and Entrepreneurial Propensity: The Mediating Role of Resilience and Locus of Control

This study aims to assess how negative life events, social norms, and need for achievement influence entrepreneurial propensity, and to examine whether resilience and locus of control mediate these relationships. To carry out this study, a quantitative methodology was used throug...

Integrated metabolomic response of grapevine fruit to foliar silicon and kaolin applications under summer stress

Climate change is intensifying drought and heat stress in Mediterranean vineyards, compromising grape composition and wine quality. Foliar applications of silicon (Si) and kaolin (Kl) have emerged as short-term sustainable strategies to enhance vine resilience; however, their com...
