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.

ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
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.

ABSTRACT Soft‐magnetic materials (SMMs) are indispensable for electrification and sustainable energy systems, yet their inherent mechanical fragility fundamentally limits applications under severe mechanical stresses. Enhancing the yield strength of SMMs is essential to prevent the degradation in magnetic performance and failure from plastic ...

Abstract Wildlife reintroductions are socioecological processes entailing the intentional movement of organisms by people. In animal reintroductions, there is growing recognition of the importance of human dimensions and efforts to integrate these into reintroduction projects. To conceptually reframe reintroductions as processes of renewed coexistence (
