Take a Break, Take Notes? The Relationship Between Pauses, Note-Taking, and Learning Performance in Instructional Videos

Although pauses in instructional videos can enhance learning, previous studies have shown that learners barely use this function. However, these studies have not examined the role of note-taking in pause use. This study investigated whether note-taking is associated with pause us...

Thalamocortical network dynamics can explain visual impulse responses and perceptual echoes

Although temporal information is ubiquitous in natural vision, the cortex shows strong intrinsic rhythmicity. Recent electroencephalogram (EEG) studies have revealed a component of the visual impulse response function (IRF) resembling a narrow alpha-band (7–13 Hz) filter with a s...

‘My Soul of Combined Saltpeter’. The Penal Colony Journal of Jean Claude Romand

Having fought in the Lyon uprising of November 1831, tailor and republican activist Jean Claude Romand (1798–1874) was sentenced to the Toulon penal colony from 1833 to 1838. There, the man who would later claim credit for coining the Canut motto – ‘Live working or die fighting’...

Global propagation of analyticity and unique continuation for semilinear waves

In this article, we develop a new method to prove both global propagation of analyticity and unique continuation in finite time for solutions of semilinear wave-type equations with analytic nonlinearity. It combines control theory techniques and Galerkin approximation, inspired b...

A 45-year high-resolution wave hindcast for the Fijian archipelago: mean climate, spectral characteristics, and long-term trends

Fiji’s coastal communities are highly exposed to ocean waves that drive erosion, inundation and shoreline change. Yet the Fijian archipelago lacks a comprehensive, wave-climate assessment at a resolution that represents island effects appropriately. To address this gap, we presen...

Quantification of absolute IgG concentration in bat sera

Abstract Bats are endowed with a remarkable capacity to withstand important pathogens through evolutionary adaptations in their immune systems. Antibodies are essential component of the adaptive immune response and serve as a crucial biomarker, indicating both present and past pa...

Episodic super-Eddington accretion as a clue to Overmassive Black Holes in the early Universe

Abstract Early JWST observations are providing growing evidence for a ubiquitous population of accreting supermassive black holes (BHs) at high redshift, many of which appear overmassive compared to the empirically-derived local scaling relation between black hole mass and host g...

Clinical Variability and Genotype‐Driven Outcomes in CHRND ‐Related Congenital Myasthenic Syndrome

BACKGROUND: Congenital myasthenic syndromes (CMS) caused by pathogenic variants in CHRND, encoding the δ-subunit of the nicotinic acetylcholine receptor (AChR), are rare, and data on genotype-phenotype correlations and long-term outcomes are limited. METHODS: We performed a retro...

Urbanisation and habitat loss favour thermophilic and monogynous ant species

Environmental changes such as urbanisation and related habitat loss and fragmentation profoundly impact ecological communities by altering habitats, resources, and microclimates. Yet, the impacts of the resulting environmental conditions on metacommunity dynamics, ranging from sp...

Multi-analytical study of the effects of secondary working and recycling in Roman glass

The impact of secondary processing and recycling on the composition and redox equilibrium in archaeological glass remains difficult to assess. This paper reports the results of a multi-analytical study of glass finds from a Roman villa in southwestern France, revealing varying mi...

Lie structures in homotopy and isotopy calculi

Abstract We establish compatibility of Lie structures that appear in homotopy calculus of functors and isotopy calculus of embeddings. On one hand, we give a new proof of the Johnson–Arone–Mahowald result describing the layers of the Goodwillie tower of the identity functor, and...

ViroSeek: a viral detection pipeline for second-generation sequencing

Abstract Arbovirus emergences represent a rising public health issue and are exacerbated by climate change and globalization. Virome analysis has become a key approach for monitoring and managing infectious diseases, yet existing tools often remain technically complex and inacces...

Delivery of multiple PspA fragments by CyaA toxoid induces broad protection against Streptococcus pneumoniae

Abstract Streptococcus pneumoniae is a leading cause of lower respiratory tract (LRT) infections and invasive pneumococcal diseases (IPD). Conjugate vaccines are effective against IPD and nasal colonization but offer coverage limited to serotypes included in the formulations. Pne...

A strong-coupling theory for polarizable symmetrically charged walls with counterions only

A pair of parallel polarizable planar walls at a distance d is considered. The walls are symmetrically charged with a uniform surface charge density, neutralized by mobile point counterions moving between them. The case of repulsive particle images is studied in the strong-coupli...

Magma-induced midcrustal flow and high-temperature metamorphism: Insights from the early Mesozoic Yunkai massif (South China) and tectonic implications

The way in which partial melting weakens the middle continental crust and triggers lateral flow is fundamental to understanding orogenic processes, yet the specific roles of magmatic heat and deformation remain debated. We addressed this issue through an integrated study of the e...

Post launch spectral and radiometric performances of MAJIS, the VIS-NIR imaging spectrometer of JUICE

Abstract. The post-launch spectral and radiometric performances of MAJIS, the VISNIR imaging spectrometer of the ESA Jupiter Icy Moon Explorer (JUICE), have been evaluated using observations performed during the Lunar-Earth Gravitational Assist (LEGA) of 19–20 August 2024 and obs...

Active learning strategies for the estimation of a feasible set defined from a vector output black-box simulator

Many industrial problems require the use of black-box numerical simulators, for which it is essential to determine the set of so-called feasible input parameters. A set of parameters is feasible if the output of the code on these parameters satisfies given constraints, for exampl...

Universal bound on microwave dissipation in superconducting circuits

Improving the coherence of superconducting qubits is essential for advancing quantum technologies. While superconductors are theoretically perfect conductors, they consistently exhibit residual energy dissipation when driven by microwave currents, limiting coherence times. Here,...

Ecosystem-scale biogenic volatile organic compound fluxes over rapeseed by eddy-covariance

Abstract. Biogenic volatile organic compounds (BVOCs) are key precursors of ozone and secondary organic aerosols, yet their emissions from croplands remain poorly characterized. Here, we report what is, to our knowledge, the first ecosystem-scale quantification of BVOC fluxes ove...

LFD (v1.0): latent-compression-free generative diffusion with geological priors and geophysical regularization for implicit structural modeling

Abstract. Diffusion models provide a promising way to model the distribution of implicit structural models, potentially improving generalization across surveys. However, existing diffusion Transformer pipelines scale poorly to high-dimensional geophysical data because noise- or v...
