A Peridynamic Framework for Modeling Progressive Failure in Porous Sandstone Indentation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A state‐based peridynamic model is proposed to simulate the failure mechanisms in porous rocks, using Bentheim sandstone as a specific example. Experimental observations reveal a transition from brittle to ductile failure under increasing triaxial compression. This behavior is attributed to pore compaction. The peridynamic model is enhanced to

Diffractive deep inelastic scattering at NLO in the dipole picture

Journal of High Energy Physics
We compute the transverse and longitudinal diffractive structure functions to full next-to-leading order accuracy in the dipole picture of deep inelastic scattering. Our calculation uses the standard light-cone perturbation theory method for the partonic

Lanthanide‐Doped NaGdF4 Nanoparticles as Versatile Luminescent Labels for Cathodoluminescence Mapping

physica status solidi (b), EarlyView.
This study presents a synthesis method for lanthanide‐doped NaGdF4 particles in an aqueous environment. Clearly distinct cathodoluminescence (CL) spectra were observed for europium‐ and thulium‐doped nanoparticles, stable for up to 100 s of excitation time.

Auger Parameter Analysis for TiN and AlN Thin Films via Combined In Situ XPS and HAXPES

Surface and Interface Analysis, EarlyView.
ABSTRACT Auger parameter analysis provides in‐depth information about electronic and chemical bonding properties of TiN and AlN thin films, which are relevant across a wide range of technologies. Meaningful interpretation and analysis of Auger parameter of these materials have been hindered due to, among other reasons, the absence of reliable ...

Weizsäcker-Williams gluon helicity distribution and inclusive dijet production in longitudinally polarized electron-proton collisions

Journal of High Energy Physics
It is well-known that the back-to-back (correlation) limit of inclusive quark-antiquark dijet production in unpolarized high energy electron-proton collisions can probe the Weizsäcker-Williams (WW) gluon transverse momentum-dependent distribution (TMD ...

Quantitative Model of Internal Analyzer Scattering in a Hemispherical Electron Analyzer and Its Application to Improve the Accuracy of the Transmission Function

Surface and Interface Analysis, EarlyView.
ABSTRACT Internal scattering within hemispherical electron analyzers (HEA) is common when operating at low pass energies, where the instrument resolution of X‐ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy experiments are at their best.

On multi-propagator angular integrals

Journal of High Energy Physics
We study multi-propagator angular integrals, a class of phase-space integrals relevant to processes with multiple observed final states and a test-bed for transferring loop-integral technology to phase-space integrals without reversed unitarity.

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

Small, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Born-Oppenheimer renormalization group for high energy scattering: the setup and the wave function

Journal of High Energy Physics
We develop an approach to QCD evolution based on the sequential Born-Oppenheimer approximations that include higher and higher frequency modes as the evolution parameter is increased.

Unlocking Energy Potential: Exploiting Anionic Redox Activity in Na‐Based Layered Oxides

Small, EarlyView.
Anionic redox in Na‐based layered oxide cathodes unlocks additional capacity beyond conventional transition‐metal redox limits, enabling high‐energy sodium‐ion batteries. This review elucidates coupled cationicanionic redox mechanisms across P2‐, O3‐, and related structural phases, while critically addressing key challenges such as voltage hysteresis ...
