Who Cares: Why the Israeli–Palestinian Conflict Matters (More) to Some EU Member States

JCMS: Journal of Common Market Studies, Volume 64, Issue 4, Page 1287-1309, July 2026.
Abstract What drives the salience of the Israeli–Palestinian conflict amongst EU member states? This article employs domestic foreign policy theories to explain the factors underlying variation in salience, estimated analysing all country statements made at the United Nations General Assembly between 1993 and 2017.

Frequency‐Dependent Acoustic Reflection Coefficients of Flat Ground Assessed Using the Sonic Boom From the OSIRIS‐Rex Sample Return Capsule Recorded on Free Flying Balloons

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Low frequency sound can travel great distances in planetary atmospheres. When these waves reflect off the air/ground interface, energy may be absorbed or transferred to mechanical waves in the subsurface. This study describes the direct and reflected acoustic wave generated by the re‐entry of the OSIRIS‐REx Sample Return Capsule captured on a ...

Optimization design of anti-creep reinforcement structure for solid rocket motor propellant grain

Jixie qiangdu
To address the creep issue that arises during the long-term vertical storage of solid rocket motor (SRM), a method was proposed that involved embedding a specially shaped functional combustible core model (reinforcement structure)into the propellant ...

A Non‐Reciprocal Architected Porous Medium

Advanced Functional Materials, Volume 36, Issue 47, 11 June 2026.
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Rejuvenated Amorphous Alloys: Processing Methods, Microstructures and Mechanical Properties

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Three rejuvenation methods – mechanical and thermal rejuvenation, and other rejuvenation routes such as ultrasonic processing – can be used to modify structures of glassy alloys, especially atomic clusters, and therefore enhances plasticity and activates work‐hardening behaviors.

Internal ballistics of solid rocket motor

, 2021
The ability to accurately model the operation of a solid rocket motor before undergoing multiple firing tests is essential. The analysis of the internal ballistics of a solid rocket motor results in a depiction of the flow properties inside the chamber, and thus, the overall motor performance.
