Domain‐Wall Circulation Gating and Pinning via Compositional Engineering of Cylindrical Nanowires

ABSTRACT Spintronic devices based on cylindrical magnetic nanowires have been proposed as a route toward three–dimensional (3D) information storage and processing by harnessing the controlled motion of domain walls (DWs). In this geometry, the Bloch‐point wall (BPW) is the charac...

Minimizer Density Revisited: Models and Multiminimizers

High-throughput sequence analysis commonly relies on k-mers and sampling schemes to improve scalability and data locality. Among these, local schemes are widely used and are typically evaluated by their density, the expected fraction of selected positions. Minimizers are the most...

Breaking the Blend: A multi-tracer kinematic decomposition method for IFS data applied to disentangling the AGN outflow and circumnuclear ring in NGC 5728 with JWST

Abstract Integral field spectroscopy (IFS) of the central kiloparsecs of active galactic nuclei (AGN) reveals a mixture of spatially coincident emission from star-formation and AGN feedback exciting the interstellar medium. Disentangling these components remains a challenge, as m...

Antarctic sea ice over the past 130 000 years – Part 2: A review of its role in the Earth system

Abstract. Antarctic sea-ice cover reached historically low levels in 2023, consistent with the simulated decrease in sea-ice extent in response to anthropogenic warming. Antarctic sea ice is closely linked to multiple components of the Earth system, thus its demise could precipit...

Characterization of Thermal Recovery Activation in Fast Photochromic Flavoprotein Charge-Transfer Complexes

Abstract A promising fast, negative, red-absorbing photochromic system based on an intraprotein intermolecular charge transfer (CT) complex between a flavin cofactor and a substrate-analogue inhibitor MXA (methylthioacetate or methylselenoacetate; X = S, Se) within monomeric sarc...

Novel geometrical test of cosmological expansion from photometric data

In tomographic cosmic-shear observations, the Bernardeau, Nishimichi, Taruya (BNT) transform allows us to build weak lensing transformed maps for which the contribution from low-redshift lenses is nulled. As this transformation depends specifically on the expansion rate of the Un...

Scenario-Based Dynamic Assessment of Rooftop Solar Photovoltaic and Heat Pump Systems for Low-Emission French Single-Family Houses

Achieving the European Union’s (EU) climate neutrality targets requires residential buildings to reduce operational carbon emissions, while increasing on-site renewable generation. However, the relative contributions of rooftop photovoltaic (PV) systems with battery storage and h...

Flexibility of the TRMT10C N-Terminal Domain Helix Explored by Molecular Dynamics Simulations

Abstract The human mitochondrial tRNA methyltransferase TRMT10C contains a 41-residue long positively charged α-helix in its N-terminal domain, interacting with tRNAs from the anticodon to the T-loops. Here, we investigated the flexibility of this N-terminal long α-helix using co...

Clinical and ecological significance of bacterial dormancy in human pathogens

SUMMARY Bacteria can enter a transient state of reduced metabolic activity to survive temporary unfavorable conditions. This phenomenon, sometimes referred to as dormancy, growth arrest, or quiescence, enables pathogen survival inside and outside of their host, with major clinica...

Challenges in reconstructing seasonally driven landslide motion from optical satellite data: insights from the Del Medio catchment, NW Argentina

Optical satellite images are a valuable resource for studying slow-moving landslides from space. However, monitoring displacement through pairwise image correlation and time-series inversion presents several challenges, including the impact of seasonality on measurement accuracy....

Validation of a new morphological diagnostic criterion in Mauritian giant tortoises of the genus Cylindraspis ( Cryptodira, Testudinidae ) thanks to paleoproteomics

A collection of Cylindraspis Fitzinger, 1835, subfossils from Mare aux Songes (Mauritius, 4,200 years BP) has recently been described. At the end of this preliminary description, only some of the 216 tortoise bones could be identified using anatomical criteria and the question of...

Probable vestibular paroxysmia mimicking benign paroxysmal positional vertigo of the superior semicircular canal in the presence of a neurovascular conflict: a case report and review of the literature

Positional vertigo is a frequent complaint in otology and vestibular physiotherapy, arising from functional or structural causes affecting the peripheral or central vestibular systems. Although benign paroxysmal positional vertigo (BPPV) is the most common form, other etiologies...

Benchmarking a new urban scheme in the ORCHIDEE 2.2 land surface model

Urban areas change natural surface energy and water balances, yet some land surface models still represent cities as natural surfaces. In this study, we present the development of a one-tile urban scheme for the ORCHIDEE land surface model, designed to improve the representation...

Geometry-enforced topological chiral fermions in amorphous chiral metals

Since the prediction and observation of topological Weyl semimetals (chiral TSMs), there have been enormous efforts to characterize further condensed matter realizations of chiral fermions. These efforts were dramatically accelerated by the subsequent discovery of a profound link...

Sensitive reverse transcription-digital droplet PCR-based discrimination of hepatitis delta virus RNAs reveals differential effects of interferon-α on viral RNA species

Hepatitis delta virus (HDV) replication relies on the production of distinct viral RNA species, including genomic (HDV-G), antigenomic (HDV-AG) and mRNAs (HDV mRNAs), which differ in abundance and function. However, the lack of sensitive and quantitative approaches allowing their...

Deciphering coccolith formation: advanced microscopy insights from the biomineralization of Gephyrocapsa huxleyi

Abstract Coccolithophores are unicellular marine phytoplankton that produce complex and intricately shaped mineralized scales called coccoliths. Coccoliths are produced in an intracellular vesicle where crystal nucleation occurs, from which several individual calcite units develo...

Long-term preservation of early-formed silicate reservoirs in the deep mantle: New insight from 146Sm-142Nd systematics in Hawaiian basalts

Short-lived radiogenic isotope systems provide unique constraints on the preservation of early-formed reservoirs in Earth's mantle. We present the largest high-precision μ 142 Nd dataset for a single hotspot, comprising 55 analyses of 29 shield-stage tholeiitic basalts from the H...

Changes in students’ self-perceived interprofessional collaborative skills following participation in the student health service program

Interprofessional collaboration is recognized as a key component of effective healthcare systems. In France, the Student Health Service (SHS) is the only mandatory and universal interprofessional training experience in health curricula. However, evidence regarding its impact on i...

Bony labyrinth taxonomic identification and long-term evolution of livestock in the Southwest and Central Asia

Abstract Southwest and Central Asia were pivotal regions for the domestication and dispersal of domestic herbivores. Here we investigate long-term variation in bony labyrinth morphology of domestic bovids (sheep, goats and cattle) across the last 10 000 years. We focused on the o...

Collective adsorption of pheromones at the water–air interface

Abstract Understanding the phase behaviour of pheromones and other messaging molecules remains a significant and largely unexplored challenge, even though it plays a central role in chemical communication. Here, we present all-atom molecular dynamics simulations to investigate th...
