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...

Covalently Linked Peptides and Membrane Potential Enable CyaA Segment Translocation
The adenylate cyclase toxin (CyaA) from Bordetella pertussis intoxicates host cells by directly translocating its N-terminal catalytic domain across the plasma membrane; however, the forces driving this unique process remain poorly defined. Here, we dissect the membrane transloca...

A source of high-energy photons, ions, and positrons can be attained with the interaction of ultra-intense femtosecond laser pulses with advanced nanostructured targets. We present and characterise a numerical model that mimics the foam deposition process on solid substrates, as...

A New Scale of Function Spaces Characterizing Homogeneous Besov Spaces
Abstract We introduce and study a new scale of function spaces that characterize the homogeneous Besov spaces $$\dot{\text {B}}^{\beta }_{p,q}$$ B ˙ p , q β , hence completing earlier work by Ullrich. These new spaces include the ones introduced by Barton and Mayboroda, and syste...

Abstract. Prediction of shallow landslides at the regional scale generally relies on statistical analyses of landslide inventories. Rainfall-duration thresholds and susceptibility maps are among the most common approaches to anticipate future landslide occurrences. However, the o...

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...

Abstract. Ground-based and satellite atmospheric observations are essential for reducing uncertainties in methane (CH4) emissions by atmospheric inversion, particularly in data-sparse regions such as Africa. However, adding new observation sites does not yield linear improvements...

Discrete adjoint gradient computation for multiclass traffic flow models on road networks
Abstract This paper applies a discrete adjoint gradient computation method for a multi-class traffic flow model on road networks. Vehicle classes are characterized by their specific velocity functions, which depend on the total traffic density, resulting in a coupled hyperbolic s...

Abstract Genomic regions of reduced recombination can preserve linkage among co-adapted alleles, facilitating local adaptation despite high connectivity. Such regions—often generated by chromosomal inversions—may be especially important in highly dispersive marine taxa yet remain...

Impact of chronic doxycycline treatment in a mouse model of tauopathy
Tauopathies are neurodegenerative disorders characterized by the accumulation of hyperphosphorylated tau, leading to synaptic dysfunction, neuroinflammation, and both cognitive and motor impairments. Doxycycline (Doxy), a tetracycline antibiotic commonly used to treat bacterial i...

Abstract Covalent organic frameworks are a family of porous crystalline structures gaining attention due to their promising applications. However, despite significant efforts, the synthesis and understanding of uniform and specific morphologies remain a challenge. Herein, we repo...

Predicting driving performance from resting-state EEG using explainable gradient boosting
Abstract Sleep deprivation substantially impairs driving performance, underscoring the need for Electroencephalography (EEG)-derived markers associated with driving-performance vulnerability under varying levels of sleepiness. In this study, resting-state EEG signals were recorde...

In arid desert environments, photovoltaic (PV) arrays not only serve as clean energy suppliers, but also act as physical barriers to mitigate wind-blown sand movement. Based on the Real-Space Cellular Automaton Laboratory (ReSCAL), this study explores the coupled effects of PV ar...

Use of waste marble powder as a cement substitute in three-dimensionally printable mortars
The potential of Tunisian marble waste as a sustainable partial substitute for cement in mortars for three-dimensional printing (3DP) for construction applications was explored. Marble powder (MP) generated from cutting and finishing processes was characterised through X-ray diff...

TSPO: a conserved mitochondrial conduit linking cellular homeostasis to disease
Abstract The translocator protein (TSPO) is an evolutionarily conserved 18 kDa protein localised to the outer mitochondrial membrane and increasingly recognised as a multifunctional regulator of cellular homeostasis. Although initially identified as the peripheral benzodiazepine...

Potential glacier contributions to the 2024 La Bérarde flood
Abstract. On 20–21 June 2024, an unprecedented flood of the Etançons river caused important damage to the village of La Bérarde (Écrins, France). An analysis of the event showed that the flood was caused by the combination of an intense rain-on-snow event at high altitude and the...

Flow past an asymmetrically confined cylinder of shear-thinning viscoelastic polymer solutions has been experimentally investigated. We show that the flow asymmetry induced by the asymmetric geometry is enhanced at Weissenberg numbers (Wi) above unity; that is, the flow in the no...

Abstract Super duplex stainless steels (SDSSs) are well known for their good mechanical properties and corrosion resistance inherited from the dual-phase microstructure with equivalent proportion of ferrite and austenite. The development of additive manufacturing has given rise t...

Abstract. Living and fossil benthic foraminifera are widely used as bioindicators of ecosystem quality, but their analysis is time-consuming. With the help of artificial intelligence, models for the automatic identification of fossil planktonic foraminifera and, more recently, be...

Abstract Biodiversity loss is accelerating globally, yet species are not equally affected, and public perceptions of extinction risk often diverge from scientific assessments. Understanding what shapes public perceptions is critical for effective conservation communication, parti...
