Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The strength and ductility trade‐off in titanium matrix composites (TMCs) is a critical factor limiting their widespread application. In this study, a (TiB + TiC)/Ti–6Al–4V composite with an optimal balance between strength and ductility was engineered via multi‐directional forging.

Individual Uncertainty and Policy Compliance During the COVID‐19 Pandemic
Risk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.ABSTRACT Ample scholarship examines the extent to which public policies in representative democracies reflect the priorities and needs of the public, often finding that individuals are unaware of many policy issues and policy responses. This may be especially true when issues of risk and scientific uncertainty are involved, which can be difficult for ...

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, Volume 37, Issue 3, Page 365-374, June 2026.ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.
