Tetragonal distortion of the multiferroic compound α‐LiFe5O8 from first‐principles calculations

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1307-1318, August 2026.
First‐principles calculations suggest the tetragonal space group P43212 for the multiferroic compound α‐LiFe5O8, with a direct band gap smaller than that in its widely known cubic space group P4332. The tetragonal lattice distortion a > c is explained by relatively strong antiferromagnetic exchange interactions parallel to the c axis and by Fe–O–Fe ...

Muscle Mitochondrial Oxidative Capacity and Cognitive Decline Over up to a Decade: Sex Differences

Aging Cell, Volume 25, Issue 8, August 2026.
Skeletal muscle mitochondrial oxidative capacity is linked to cognition and predicts cognitive decline primarily in men. Underlying mechanisms appear to differ by sex, likely through a metabolic‐drive pathway in men and a hematologic‐inflammatory pathway in women.

South Korea's THAAD Decision at the Domestic–International Nexus: Preferences, Information, and Constraints

Pacific Focus, Volume 41, Issue 2, Page 175-188, August 2026.
ABSTRACT South Korean President Park Geun‐hye's 2016 decision to authorize the deployment of the U.S. Forces Korea THAAD system—and Beijing's subsequent economic and diplomatic coercion—marked a decisive inflection point in Seoul's China policy.

Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

Plant, Cell &Environment, Volume 49, Issue 8, Page 5689-5702, August 2026.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

Atomic Simulations of Volatile Coverage on Silicate Surfaces

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Understanding how surface processes shape exosphere formation on airless bodies is limited by how surface properties influence the ejection of volatiles such as Na. Recent studies show that retention and release are sensitive to surface binding energy (SBE), motivating the need for SBE values as a function of mineral type and surface coverage.

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Modern thermoplastic (hot glue) versus organic-based adhesives and haft bond failure rate in experimental prehistoric ballistics

, 2021
The prehistoric production of composite technologies throughout human evolution was facilitated greatly by the use of adhesives. One such technology was projectile weaponry, which used adhesive to attach a stone point to a wooden shaft.

BALLISTICS FOR THE NEUROSURGEON

Neurosurgery, 2008
Craniocerebral injuries from ballistic projectiles are qualitatively different from injuries in unconfined soft tissue with similar impact. Penetrating and nonpenetrating ballistic injuries are influenced not only by the physical properties of the projectile, but also by its ballistics. Ballistics provides information on the motion of projectiles while
