A Dichalcogenide-Protected Pt@Au12@Ag8 Nanocluster
Abstract Precise control over the location of heterometal atoms in alloy nanoclusters is essential for understanding how metal distribution governs superatomic structure and properties. Herein we show that PtAg20[S2P(OPr)2]12 (PtAg20) can serve as a structurally defined precursor...

Deep learning reveals ecological decoupling and rate heterogeneity in Hymenoptera wing evolution
Quantifying biomorphological evolution and integrating phenotypic data into large-scale ecological and evolutionary studies are often limited by the scalability, subjectivity, and poor interpretability of existing methods. We introduce HAIKA (Hierarchical Attention-based Interpre...

Ice Converts Phenols into Persistent Mineral-Bound Polymers
Abstract Freezing fundamentally alters how minerals transform dissolved phenols in cold environments. As water freezes, solutes are excluded from the crystal lattice and concentrated into microscopic pockets of unfrozen liquid, creating reaction conditions far more extreme than t...

Wavelength-Selective Magneto-Optical Diodes Based on Rare-Earth Chiral Molecular Crystals
Abstract Chiral materials, integrating structural breaking of mirror-symmetry, exhibit physical properties that cannot be observed in centrosymmetric analogues. Among these properties, optical magneto-chiral anisotropy, the nonreciprocal absorption of light shown by chiral magnet...

Advancements in sustainable cement technology rely on the use of supplementary cementitious materials to enhance performance and reduce environmental impact. Mineral additives such as fly ash (FA), blast-furnace slag, silica fume and limestone are commonly used to lower clinker c...

The geometry of gametic dispersal in a flying mammal, Rhinolophus hipposideros
Abstract Dispersal influences population and evolutionary dynamics, in a manner that depends on by which dispersal strategies gene flow occurs. In some species, mating partners move exclusively for mating, dispersing genes but not individuals. This is the case in many bat species...

Autoimmune and inflammatory diseases associated with T-cell clonal expansion
Autoimmune and inflammatory diseases (AID) result from a breakdown of immune tolerance, often driven by T-cell dysregulation and sometimes associated with clonal T-cell expansion. While T-cell large granular lymphocyte leukemia (LGL-L) is a well-defined clonal disorder commonly a...

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...

Antichains for Concurrent Parameterized Games
Concurrent parameterized games involve a fixed yet arbitrary number of players. They are described by finite arenas in which the edges are labeled with languages that describe the possible move combinations leading from one vertex to another (n players yield a word of length n)....

Design principle for mitigating moisture-induced degradation in 2D halide perovskites
We establish a conceptual framework which explains and mitigates moisture-induced degradation in 2D perovskites. Degradation proceeds along defined pathways across the spacer cation iodide (A′I or A′I2)-PbI2-H2O ternary phase diagram as moisture intercalates into the perovskite....

Transarterial embolization in musculoskeletal care: an indication-stratified narrative review
Abstract Background Transarterial embolization (TAE) is increasingly used across a broad spectrum of musculoskeletal conditions, ranging from established hemostatic and tumor-related indications to emerging pain-directed procedures for degenerative joint disease and chronic infla...

TAIL EXPECTILE ESTIMATION IN THE SEMIPARAMETRIC GENERALIZED PARETO MODEL
Expectiles have received increasing attention as a market risk measure that is both coherent and elicitable. They are defined as a least squares analog to quantiles. Their estimation from heavy-tailed loss data in an extreme value framework is an important and difficult problem,...

Nonlocal Hamilton–Jacobi Equations on a network with Kirchhoff type conditions
In this article, we consider nonlocal Hamilton–Jacobi Equations on networks with Kirchhoff type conditions for the interior vertices and Dirichlet boundary conditions for the boundary ones: we provide general existence and comparison results in the case when the nonlocal operator...

Unsupervised anomaly detection (UAD) based on deep generative modelling has been increasingly investigated for identifying pathological brain abnormalities without requiring voxel-level annotations. By learning the distribution of healthy anatomy and generating pseudo-healthy rec...

Design of Small Circularly Polarized Luminescence-Active Planar-Chiral Azaboroles
Abstract We report an enantioselective approach toward new planar-chiral azaboroles bearing the [2.2]paracyclophane unit and studies of their (chir)optical properties. Fusing the planar-chiral scaffold with a B,N-heterocycle led to the formation of a set of three substances, all...

Building-block synthesis as a determinant of antibiotic persistence
Reduced antibiotic target activity is a major driver of antibiotic treatment failure. While this has mostly been linked to the presence of low-energy bacteria, a recent study by Taher and colleagues suggests that reduced building-block synthesis can also promote antibiotic surviv...

Our article studies the main features of a constitutionalism trend reflected in the influence of private interest groups over jurisdictional expansion and interpretative advances operated by the European Court of Human Rights. We posit that liberal interests’ litigation bears pot...

Deterministic mean field games on networks and related optimal control problems
We study deterministic mean field games and related optimal control problems, with finite time horizon and a network as state space. An agent controls her velocity and, when she occupies a vertex, she can either remain still or enter any adjacent edge. The costs are continuous in...

WKB for semiclassical operators: How to fly over caustics (and more)
The method initiated by Wentzel, Kramers, and Brillouin to find approximate solutions to the Schrödinger equation lies at the origin of the spectacular development of microlocal and semiclassical analysis. When used naively, the approach appears to break down at caustics, but Mas...

Abstract Direct X-ray detection in two-dimensional (2D) hybrid metal-halide perovskites is dictated by the interplay between organic spacer chemistry, crystal structure, and charge transport. Among these materials, the metformin (MF2+)-based perovskite MFPbI4 has recently emerged...
