Hidden in historical sources: Rediscovering the thorny oyster (Spondylus gaederopus Linnaeus, 1758) in art, archives, and cultural knowledge

The thorny oyster ( Spondylus gaederopus ), a Mediterranean bivalve prised during prehistoric times for its distinctive spiny purple shell, has since been overlooked in cultural and scientific records. Frequently depicted in Early Modern still-life paintings, particularly in Ital...

Assessing dengue knowledge, attitudes and preventive practices in France and Italy: A cross-sectional study using participatory surveillance cohorts

The dengue virus, transmitted by Aedes mosquitoes, causes an estimated 100–390 million infections annually worldwide. With no treatment available, mitigation and prevention involve reducing mosquito breeding and limiting feeding opportunities. Due to changing climate conditions,...

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain. This limits me...

Process-oriented evaluation of machine learning and physics-based models for wave parameter prediction under extreme conditions in a fetch-limited sea

Machine learning approaches are increasingly used for wave prediction, yet their ability to represent the physical processes governing extreme waves in fetch-limited seas remains insufficiently understood. This study evaluates four machine learning models for reconstructing signi...

Micro-scale organization of non-cyanobacterial diazotrophs drives nitrogen fixation in marine particles

Abstract Dinitrogen (N₂) fixation supplies reactive nitrogen to the ocean, and non-cyanobacterial diazotrophs (NCDs) are increasingly recognized as contributors. Marine particles have been theorized as hotspots where low oxygen and labile carbon favor N₂ fixation by NCDs, but emp...

The Balbi operational model, a simplified physical model for surface fires. Part I – modelling

Background Previously published versions of the ‘Balbi model’ describing surface fire propagation consist of a set of equations based on simplified conservation laws. Their main equation calculating the fire rate of spread (ROS) relied on an iterative process to account for the e...

The Balbi operational model, a simplified physical model for surface fires spread. Part II – model parameterisation and evaluation

Background The ‘Balbi model’ is a simplified physical model for surface fires which provides the main physical characteristics of a fire front and its rate of spread (ROS) as a function of general environmental conditions. In the first part of this work, we describe a simplificat...

Improved recipes for peculiar velocity power spectra using Evolution Mapping

Abstract We present new fitting functions for the velocity divergence auto- and cross-power spectra, Pθθ(k) and Pδθ(k), calibrated on gravity-only N-body simulations. By applying the Evolution Mapping framework, we revise existing prescriptions to introduce a physically motivated...

Fewer players, bigger opportunity: How structural rule modifications shape physical and technical demands in youth rugby union

Purpose Youth rugby governing bodies have progressively revised competition formats to align game demands with children's developmental characteristics. However, empirical evidence remains limited on whether these structural modifications increase children's locomotor and technic...

Magnetic Field Tuning of Modulated Magnetic Orders in CrOCl at the Two‐Dimensional Limit

Chromium oxychloride is a van der Waals magnet with intrinsic competing exchange interactions, including a strong antiferromagnetic one, source of a very rich magnetic phase diagram, with ferrimagnetic, antiferromagnetic, and canted states, up to high magnetic fields. We investig...

Entropy maximization and weak Gibbsianity of quasi-free fermionic states

Abstract In their 1972 study of approach to equilibrium, Lanford and Robinson showed that gauge-invariant quasi-free states of lattice fermions maximize entropy among all translation-invariant states with a fixed two-point function and suggested that the maximizer is unique. In s...
