The Contribution of DAS to the Routine Monitoring of Seismicity in Oceanic Islands: The Case for Faial (Azores)

Distributed acoustic sensing (DAS) deployed on submarine telecom cables is bound to revolutionize the earthquake monitoring routine currently performed by seismic network operators, particularly in domains where most seismic activity originates offshore. In this work, we analyze...

Molecular mechanism of complement interference by Streptococcus pyogenes nuclease A

Abstract Bacteria deploy virulence factors to subvert host immunity; yet the molecular details of these interactions often remain limited. Here, we reveal the structure and host interactome of the Streptococcus pyogenes nuclease A (SpnA). We characterize the structure and dynamic...

Zinc dimethacrylate-modified epoxy coating for corrosion protection and self-healing

Corrosion-related asset losses and safety risks are increasing the need for smarter protective coating strategies. In this work, zinc dimethacrylate (ZDMA) was incorporated into epoxy coatings for enhanced corrosion protection for carbon steel. The successful integration of ZDMA...

Ethnobotanical and phytochemical insights into native and naturalized plants for cashew pest control in Guinea-Bissau

Abstract Essential oils are increasingly recognized as ecofriendly alternatives to synthetic pesticides, especially in tropical regions with high pest pressure and limited crop protection resources. This study evaluates native and naturalized plants in Guinea-Bissau— Ageratum con...

Trade fairs as relational network spaces: catalysing sustainable innovation. A study in the footwear industrial network

Purpose This paper aims to investigate how trade fairs (TFs), conceptualised as relational network spaces (RNS), catalyse sustainable innovation (SI) through changes in business relationship dynamics. It investigates how interactions at TFs stimulate SI at three analytical levels...

Regional-Scale Multi-Hazard Assessment of Earthquake-Induced Road Network Disruption

Recent earthquakes have shown that earthquake-induced landslides and liquefaction can severely disrupt transportation systems and generate significant direct and indirect losses. Still, these secondary hazards are rarely incorporated into regional road-network disruption assessme...

Producing Post-Conflict Urban Dili (Timor-Leste): Temporal Misalignment of Planning, Legislation and Budgeting Systems

Post-conflict cities are often understood as an outcome of fragmented governance, where coordination is limited, power is centralized and where spatial planning and urban development are often neglected and under-resourced across governance scales. This paper examines how tempora...

ERGA-BGE Reference Genome: Corema album ((L.) D. Don, 1830) - the Portuguese crowberry, endemic to the Iberian Peninsula.

Corema album is a perennial, dioecious shrub endemic to the Atlantic coast of the Iberian Peninsula and the Azores. It inhabits coastal dune ecosystems from Galicia to the Strait of Gibraltar, where it plays an important ecological role. The goal of this study was to assemble and...

Experimental Assessment of Predamage Effects and Analytical Prediction of Debonding Load in FRCM Shear-Strengthened RC Beams

Abstract This study investigates the shear behavior of reinforced concrete (RC) beams strengthened with unanchored polyparaphenylene benzobisoxazole fabric-reinforced cementitious matrix (PBO-FRCM) U-wrap systems, with particular emphasis on debonding-controlled failure mechanism...

Central nervous system manifestations in hereditary transthyretin amyloidosis: a cross-sectional study with 151 patients

Abstract Background Central nervous system (CNS) dysfunction is increasingly recognized in hereditary transthyretin (ATTRv) amyloidosis. We aimed to characterize CNS manifestations and assess associations with clinical variables and plasma neurofilament light chain (NfL), using h...

Typology and critical analysis of structural and institutional barriers to sustainable intensification education in Nigeria and Ghana: A systematic review

Background The ongoing issues of food insecurity, poverty, and environmental degradation in West Africa make sustainable intensification (SI) essential. To combat these challenges, scholars and policymakers increasingly agree that training and education in SI is necessary, partic...

Generational changes in lung function in adults from several world regions: results from the Burden of Obstructive Lung Disease study

This study estimated birth cohort effects on lung function using BOLD (Burden of Obstructive Lung Disease) data from 28 569 adults born between 1902 and 1976 across 41 sites in 34 countries. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1 ) and the FEV 1 /FVC...

Deciphering the genomic signatures of climate vulnerability across 77 sheep breeds

Abstract Among domesticated species, sheep ( Ovis aries ) have achieved a wide geographic distribution due to their mobility, rusticity and ability to adapt to diverse environments and climatic conditions. Here, we characterise the genome-wide diversity of >1,000 sheep representi...

Ageing of Goat Meat: Physicochemical Aspects, Sensory Changes and Quality Improvement Strategies

Goat meat ageing is a promising strategy for improving meat quality and adding value to meat from adult animals. This review aimed to provide an integrated overview of goat meat ageing, focusing on biochemical, technological, physicochemical, sensory and microbiological aspects....

Navigating the New Ecology of Uncertainty: Governance, Leadership, and the Path to Institutional Resilience

ABSTRACT : Crisis management has consolidated itself as an indispensable strategic competence in a context marked by systemic volatility, global interdependence, and technological acceleration. The contemporary ecology of uncertainty—characterized by disruptive geopolitical pheno...

Event-triggered neural network adaptive hybrid attitude control

In this paper, we develop an adaptive controller for rigid-body attitude tracking systems that combines a neural network architecture with an event-triggered mechanism. We design a quaternion-based nonlinear controller that employs a neural network to compensate for state-based d...

Characterization of the Healthy Ocular Mycobiome of Purebred Lusitano Horses Using Oxford Nanopore Long-Read Sequencing

The ocular surface represents a unique microbial ecosystem continuously exposed to environmental microorganisms; however, the fungal component of the healthy equine ocular microbiome remains poorly characterized. This study aimed to characterize the ocular surface mycobiome of 12...

Enhancing interpretability in metabolomics: ranking metabolites by their impact on graph neural network predictions

Abstract A key step in the biological interpretation of untargeted metabolomics data is the ranking of compounds by importance, usually using statistical significance or impact on classification as the basis for importance assignment. However, current approaches treat metabolites...

A quantitative framework for evaluating overburden disturbance and surface subsidence induced by coal seam mining

Abstract Coal seam mining inevitably causes varying degrees of disturbance to the overlying strata and surface environment, necessitating the establishment of a scientific and systematic quantitative assessment framework for overburden disturbance. This study introduces a compreh...

Cavell and Deleuze: Genre as Medium, Death as Image

This paper proposes the concept of the “death-image” as a point of convergence between the film-philosophies of Stanley Cavell and Gilles Deleuze. While Cavell and Deleuze are rarely brought together—given Cavell’s emphasis on ordinary language, skepticism, and ethics, and Deleuz...
