Abstract Electrochemical hydrogenation of lignin-derived aromatics offers a route to biomass upgrading, but controlling methoxy retention versus cleavage remains challenging. Here, we compare carbon-supported Rh, Pt, Ru, and Pd catalysts for guaiacol conversion under identical co...

Neural machine translation (NMT) can produce fluent output while systematically deforming domain-critical terminology in metrological standards. Under GUM (JCGM 100:2008) Annex D.1.1, an incomplete definition of the measurand is a possible source of measurement uncertainty; termi...

Bulk metallic glasses (BMGs) are distinguished by amorphous atomic structures that confer superior mechanical performance; however, the evolution of these properties in ternary bulk configurations remains insufficiently explored. In this study, we employed large-scale molecular d...

Isogeometric analysis for explicit wave propagation in poroelastic media
For higher-order discretizations of explicit dynamics problems, Isogeometric Analysis (IGA) has several favorable properties as compared to classical Finite Element Analysis (FEA). While FEA produces spurious modes at orders beyond linear, this is not the case for IGA. Consequent...

Continuous-Wave SOFISM with SPAD Array Detection
We present a continuous-wave (CW) implementation of super-resolution optical fluctuation imaging with image scanning microscopy (SOFISM) using a pixelated single-photon avalanche diode (SPAD) detector camera. In a scanning-based geometry, SOFISM requires fluorescence fluctuations...

Oxygen deficiency and valency reconstruction in multiferroic V-doped HfO 2
The interplay of oxygen deficiency and vanadium multiple valency in the candidate multiferroic V-doped P c a 2 1 hafnia HfO 2 is studied by first-principles calculations. Low-lying V majority gap states accept electrons from oxygen-vacancy donors, reducing their formation energy,...

Abstract Room temperature HERFD XAS (High Energy Resolution Fluorescence Detected X-ray Absorption Spectroscopy) data collected on the stable Fe(III)Fe(III) (ox) and Fe(II)Fe(II) (red) states of the soluble methane monooxygenase hydroxylase (sMMOH) from Methylosinus trichosporium...

Engineering ordered two-dimensional defect phases to strengthen structural alloys
Defects in crystals are usually considered to be consequences of deformation, but they can also be engineered as strengthening features. Planar defects can strengthen structural alloys but usually form only during deformation or service, limiting control over their density, stabi...

Meta-analytic structural equation modeling (MASEM) is a flexible modeling framework that combines the strengths of meta-analysis and structural equation modeling. Despite the increasing popularity of the MASEM technique, its usage and scope are limited to relatively simple meta-a...

Dimensionality-Driven Charge Stabilization of Group-IV Color Centers in Diamond Ultrathin Films
Abstract Neutral group-IV vacancy (XV, X = Si, Ge, Sn, and Pb) centers in diamond are promising solid-state spin-photon interfaces owing to favorable spin coherence and inversion-symmetry-protected optical transitions. However, stabilizing their neutral charge state typically req...

Regular and chaotic dynamics of nonlinear optomechanical systems controlled by modulated light
The nonlinear dynamics of a mechanical resonator in an optomechanical system with linear, quadratic and cubic photon-vibration interactions (with respect to mechanical displacements) in a modulated driving field under conditions of adiabatic elimination of the optical field is st...

Preserving T cell cytotoxic function during ex vivo expansion remains a major challenge for adoptive cancer immunotherapy. A synthetic immune niche (SIN) composed of immobilized CCL21 and ICAM1 was shown to improve T cell expansion while preserving cytotoxicity; however, it remai...

Discovering the axiverse via fifth forces
If the Universe is described by string theory or other extensions of the Standard Model, several light, axion-like states are predicted to exist. However, most experiments only search for one of these states. We show that searches for fifth forces can't assume a non-relativistic...

Institutional context and the employment effects of artificial intelligence in European SMEs
Using novel data from the Survey on Access to Finance of Enterprises covering the last quarter of 2025 and an Inverse Probability Weighted Regression Adjustment approach, we assess the conditional treatment effects of artificial intelligence (AI) use on the likelihood of employme...

High-accuracy correlated four-component relativistic electronic structure methods are typically formulated in terms of integrals over molecular orbitals (MOs). Consequently, an efficient and scalable strategy is required to deal with the complexity of transforming relativistic tw...

Spectral theory of energy-selective quantum search with Ising Hamiltonian phase oracles
We develop an exact spectral-response theory for the Grover-type iterate \(W_T=D_ξ\exp(-\ii T H)\), in which the evolution generated by a diagonal Ising Hamiltonian is used directly as a continuous phase oracle. An energy-grouped recurrence and its generating-function solution sh...

This article discusses endophytic fungi isolated from the medicinal plant Althaea officinalis L. (marshmallow), their ability to produce secondary metabolites, and the possible biological activity of these metabolites. Althaea officinalis L. is a pharmacologically valuable plant...

Seasonal surface melt onset and firn freeze-up across the central Wrangell and St. Elias Mountains
Abstract. High-elevation alpine firn is increasingly influenced by surface melt and meltwater retention, yet the spatial extent and timing of these processes remain poorly quantified. Here we present spatially distributed estimates of seasonal surface melt onset and firn freeze-u...

Quantum optics of chiral and antichiral waveguide arrays
We study single-photon scattering by atoms in arrays of one-way waveguides. We investigate both chiral and antichiral arrays, where the one-way waveguides are aligned in the same and opposite directions, respectively. In the chiral array, reciprocity is broken: one of the (spatia...

Temporal cavity solitons generated in monochromatically driven dispersive Kerr resonators offer an attractive avenue for on-chip optical frequency comb generation. Key to many of their applications is to understand how noise -- both technical and quantum -- affects the soliton st...
