Mechanoluminescence of a Ba4Si6O16:Eu2+, Ho3+‐Containing Glass‐Ceramic: Experiments Under Different Loading Modes and Modeling

physica status solidi (a), Volume 223, Issue 10, 22 May 2026.
A glass‐ceramic from the BaO‐SiO2 chemical system emits light under mechanical loading provided it was submitted to UV irradiation prior to mechanical loading. This phenomenon is known as elasto‐mechanoluminescnence and, in the present case, it occurs thanks to the incorporation of a few percents of europium and holmium and an original synthesis route ...

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Stress Field and Megathrust Strength in the Western Hellenic Subduction System: Insights From the 2024 Mw 5.9 Strofades Earthquake Sequence, Greece

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A M5.9 earthquake occurred on 29 March 2024, offshore near the Strofades Islands, in the western Hellenic Subduction System. Here we present high‐precision earthquake locations and focal mechanisms that suggest the rupture of a NNE‐SSW striking, left‐lateral strike‐slip fault.

Antarctic Geothermal Heat Flow, Crustal Conductivity and Heat Production Inferred From Seismological Data

Geophysical Research Letters
Geothermal heat flow is a key parameter in governing ice dynamics, via its influence on basal melt and sliding, englacial rheology, and erosion. It is expected to exhibit significant lateral variability across Antarctica.

L'atténuation intrinsèque des ondes sismiques. Première partie : Définitions et mesures Intrinsic Attenuation of Seismic Waves. Part 1: Definitions and Measurements

Oil & Gas Science and Technology, 2006
La notion d'atténuation acoustique est séparée en deux types, à savoir l'atténuation intrinsèque, liée au milieu poreux et à ses fluides saturants et l'atténuation extrinsèque liée à la géométrie du milieu poreux.

Regional Adjustments to NGA‐West2 Ground‐Motion Models for Turkey

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1313-1332, May 2026.
ABSTRACT This paper presents a ground‐motion model updating (GMMU) framework to adjust NGA‐West2 models for predicting a set of intensity measures in Turkey, including peak ground acceleration (PGA), peak ground velocity (PGV), and pseudo‐spectral acceleration (PSA) at periods ranging from 0.01 to 10 s. The GMMU framework integrates bias identification

Estudio de la sensibilidad a la velocidad de deformación en régimen superplástico del inconel 718 mediante ensayos con perturbación cíclica de la velocidad de deformación

Boletín de la Sociedad Española de Cerámica y Vidrio, 2004
The imposition of a sinusoidal perturbation of variable frequency to the strain rate of a material subjected to a monotonic tensile test is an easy technique to study the kinetics of plastic deformation that has been scarcely used.

Ground‐Motion Characterization for the 2025 U.S. National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands

Earthquake Spectra, Volume 42, Issue 2, May 2026.
We develop the ground‐motion characterization (GMC) for the 2025 U.S. National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands (NSHM‐PRVI) for earthquakes in active crustal, subduction interface, and subduction intraslab regimes. Using ground‐motion models (GMMs) from the Next‐Generation Attenuation (NGA)‐West2 and NGA‐Subduction ...
