Global scripts for local policies: Front-of-pack nutrition labeling in Latin America

This article examines the remarkable similarity and near-simultaneity of the front-of-pack nutrition labeling regulations adopted across Latin America over the past two decades. Drawing on the world society theory, we argue that this convergence cannot be adequately explained as...

Deterministic Promotion of Findings in Agentic Offensive Security: Verifier Oracles over LLM-as-Judge

This research presents RootViel, an agentic offensive-security platform built on the MINERVA engine, introducing a deterministic approach to verifying security findings generated by autonomous AI agents. The work addresses a fundamental limitation of contemporary multi-agent secu...

Water relations and leaf area dynamics in a short-rotation coppice willow plantation during the growing season

In short-rotation coppice (SRC) willow (Salix spp.) bioenergy plantations, productivity is mainly determined by water availability and light interception. Thus, the aims of this work were: to analyse the effects of water availability (irrigated and rainfed), planting density (13,...

Orthoptera assemblages in subtropical paddy fields: role, effect of plant phenology, and cultivation area

Abstract Irrigated rice crops are considered artificial wetlands, with high productivity and biodiversity, especially in insect populations such as orthopterans. Although these predominantly herbivorous insects include several species of agricultural concern, their occurrence and...

The auditory region of Acarechimys minutissimus (Rodentia, Hystricognathi) from the Early Miocene of the Argentinean Patagonia: considerations in the evolution of Pan-Octodontoidea

The auditory region of mammals is a crucial source of anatomical, biological, and evolutionary information. Despite the taxonomic diversity and ecological importance of caviomorph rodents, the auditory morphology of their fossil representatives remains poorly known. Here we descr...

The Semantic Refinement Pattern: A Distributed Architecture for LLM-Enhanced Smart Contract Security Analysis

Static analysis tools for software security produce high volumes of findings with significant false positive rates, requiring substantial manual triage. We present the Semantic Refinement Pattern, a software architecture where traditional analysis tools execute in parallel while...

Physicochemical and sorption properties of Jerusalem artichoke flour and their implications for storage stability

Jerusalem artichoke flour (JAF) has emerged as a sustainable ingredient with significant prebiotic potential due to its inulin content; however, the relationship between its physicochemical properties and functional stability remains insufficiently understood. This study provides...

Leaf Developmental Stage at Harvest Affects Postharvest Senescence and Quality Parameters of Kale

Background: Kale is a vegetable of the Brassicaceae family recognized for its high nutritional value. After harvest, kale leaves undergo senescence, characterized by the loss of green color due to chlorophyll degradation. This deterioration affects organoleptic quality and consum...

Are nocturnal home and ambulatory blood pressure measurements clinically interchangeable during high-risk pregnancy?

Nocturnal blood pressure is a strong predictor of adverse maternal–fetal outcomes, particularly preeclampsia. While 24-h ambulatory blood pressure monitoring (ABPM) is the reference method for nocturnal blood pressure assessment, home blood pressure monitoring (HBPM) devices capa...

Satellite telemetry suggests significant regional variation in post-fledging survival of Adélie penguins

Abstract Post-fledging periods represent one of the most vulnerable stages for juvenile seabirds. Adélie penguins Pygoscelis adeliae must quickly develop foraging skills while minimizing predation risk immediately after fledging. In the Antarctic Peninsula (AP) region, where popu...

Cost–Accuracy Trade-Offs in Unpaved Rural Road Condition Assessment: Visual Indices and Smartphone-Based IRI in the Ecuadorian Andes

More than 90% of the road network of Loja, Ecuador, is unpaved and lacks an official condition metric. Low-cost measures relate to the IRI on pavements, but not demonstrably on unpaved roads. A 15 km Andean corridor was surveyed in one dry season with four visual–manual indices (...

Conserved Epithelial Remodeling Programs Underlie Pediatric Juvenile Colorectal Polyps Associated with Allergic Sensitization

Juvenile colorectal polyps (JP) are the most common polypoid lesions of the colon in children and the leading cause of lower gastrointestinal bleeding in pediatric patients. Although histologically classified as benign hamartomatous lesions, they arise in a context of allergic se...

Genome skimming reveals a multipartite mitochondrial genome in the parasitic nematode Dioctophyme renale

Abstract Background Dioctophyme renale , known as the “giant kidney worm,” is a parasitic nematode of significant medical and biological importance due to its large size and complex interactions with various mammals, including humans, causing dioctophymiasis. Despite its importan...

Environmentally friendly corrosion protection for aluminum using an Acacia mearnsii tannin-based primer

This study evaluates the anticorrosive potential of mimosa tannin, a natural extract from Acacia mearnsii bark, on aluminum in neutral chloride environments. Electrochemical techniques, including linear polarization resistance, open circuit potential, and potentiodynamic polariza...

Quantifying Heartbeat Micro-Fragmentations Post-Myocardial Infarction Using Wavelet Entropy and Complexity

Cardiovascular diseases are recognized as one of the leading causes of mortality, with myocardial infarction (MI) being a critical condition that disrupts the heart’s electrical conduction due to myocardial tissue damage. The aim of this study is to examine two key phases followi...

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, partic...

KINOTECA: A Navigator of Chemical Datasets with Reported Kinase Inhibitory Activity

Protein kinases are the most intensively targeted protein family for small-molecule drugs, and the large volume of inhibitory-assay data reported for them makes the family particularly well suited to data-driven and machine-learning approaches to drug discovery. This data, howeve...

Improved Purification and Quantitative Kinetics Monitoring of Triatoma virus Infection of Rhodnius prolixus

Chagas disease control relies on chemical interventions, currently compromised by insecticide resistance. Triatoma virus (TrV) emerges as a biological candidate, requiring standardized methodologies to purify, quantify, and relate viral doses to biological effects in triatomines....

Intravascular ultrasound–guided versus angiography-guided endovascular interventions for peripheral artery disease: a systematic review and meta-analysis

Abstract Background Endovascular revascularization is a cornerstone therapy for peripheral artery disease (PAD), typically guided by angiography, which may underestimate vessel size and lesion complexity. The clinical benefit of intravascular ultrasound (IVUS) guidance remains un...

Spin Waves without Spin Waves: A Case for Soliton Propagation in Starling Flocks

Collective turns in starling flocks propagate linearly with negligible attenuation, indicating the existence of an underdamped sector in the dispersion relation. According to linear response theory, beside granting linear propagation of the phase perturbations, the real part of t...
