Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

Small, EarlyView.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

Dimuons from neutrino-nucleus collisions in the semi-inclusive DIS approach

Journal of High Energy Physics
We present a next-to-leading order perturbative QCD calculation of dimuon production in neutrino-nucleus collisions. This process is typically calculated by assuming it to be proportional to inclusive charm production, which requires an effective ...

Raman Microspectroscopy for Structural Indication in Ultrafast Laser Writing

Small Methods, EarlyView.
Raman microspectroscopy is demonstrated as an in situ, phase‐specific probe for femtosecond laser fabrication in diamond. Multiple spectral indicators are systematically evaluated and correlated with electrical performance, establishing a robust methodology for process monitoring.

Towards unifying perturbative and Holographic Light-Front QCD via holomorphic coupling

Journal of High Energy Physics
We construct a QCD coupling A $$ \mathcal{A} $$ (Q 2) in the Effective Charge (ECH) scheme of the canonical part d(Q 2) of the (inelastic) polarised Bjorken Sum Rule (BSR) Γ ¯ 1 p − n $$ {\overline{\Gamma}}_1^{\textrm{p}-\textrm{n}} $$ (Q 2).

AstroECP: towards more practical electron channeling contrast imaging

Journal of Applied Crystallography, EarlyView.
We explore and address many of the major challenges associated with using electron channeling contrast imaging in a scanning electron microscope, with the goal of more easily revealing and characterizing crystalline defects such as dislocations.Electron channeling contrast imaging (ECCI) is a scanning electron microscope based technique which enables ...

An FONLL prescription with coexisting flavor number PDFs

Journal of High Energy Physics
We present a new prescription to account for heavy quark mass effects in the determination of parton distribution functions (PDFs) based on the FONLL scheme.

Complete N f 2 $$ {N}_f^2 $$ contributions to four-loop pure-singlet splitting functions

Journal of High Energy Physics
The scale evolution of parton distributions is determined by universal splitting functions. As a milestone towards the computation of these functions to four-loop order in QCD, we compute all contributions to the pure-singlet quark-quark splitting ...

Absolute scaling of small‐ and wide‐angle X‐ray scattering images recorded with short duration X‐ray pulses on a large area fiber‐taper X‐ray detector

Journal of Synchrotron Radiation, EarlyView.
An X‐ray scattering setup designed to capture small‐ and wide‐angle X‐ray scattering on a single, large area detector features a partially transmissive beamstop that facilitates non‐invasive recording of X‐ray beam position and intensity during acquisition of X‐ray scattering images.

Forward production of a Drell-Yan pair and a jet at small x at next-to-leading order

Journal of High Energy Physics
We perform the analytical next-to-leading order calculation of the process p + A γ ∗ + jet + X, at forward rapidities and low x. These kinematics justify a hybrid approach, where a quark from the ‘projectile’ proton scatters off the gluon distribution of
