Pseudoriemannian metrics on spaces of bilinear structures

open access: yes, 1991
The space of all non degenerate bilinear structures on a manifold $M$ carries a one parameter family of pseudo Riemannian metrics. We determine the geodesic equation, covariant derivative, curvature, and we solve the geodesic equation explicitly.

Sociolinguistic variation in the rhythm of Nigerian English speech

open access: yesWorld Englishes, Volume 45, Issue 1, Page 125-143, March 2026.
Abstract There is a dearth of research on speech rhythm in Nigerian English, and scholars have differing views on its nature, ranging from being syllable‐timed to tone‐timed. Apart from the fact that the majority of few available studies were conducted more than a decade ago, the exact nature of speech rhythm in Nigerian English remains contentious ...

Injectable Dual‐Crosslinked Poly(oligo(Ethylene Glycol) Methacrylate) Hydrogels Inspired by Mussel Adhesion for Cutaneous Wound Healing and Functional Tissue Regeneration

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 5, 2 February 2026.
Injectable POEGMA‐DA hydrogels, dual‐crosslinked via dopamine self‐polymerization and dynamic hydrazone bonds, provide a safer alternative to invasive wound closure methods and toxic bioadhesives. Mimicking skin‐like mechanics, they achieve effective tissue adhesion for acute dermal wounds, supporting improved healing outcomes, including reducing ...

Targeting Adipose Tissue Function Protects Against Heart Failure with Preserved Ejection Fraction

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
This study explores the role adipose tissue (AT) phenotypes have in determining cardiovascular outcomes in an obesity‐related heart failure with preserved ejection fraction (HFpEF) model. Pharmacological induction of thermogenesis promoted resilience to HFpEF‐induced remodeling of AT and conferred cardioprotection. Surgical and genetic models confirmed

S-regular functions which preserve a complex slice

open access: yes, 2018
We study global properties of quaternionic slice regular functions (also called s-regular) defined on symmetric slice domains. In particular, thanks to new techniques and points of view, we can characterize the property of being one-slice preserving in ...

Novel Application of UHPLC–MS, HRMS, and 2D‐NMR for Structural Elucidation of Eletriptan Hydrobromide and Its Novel Degradation Products

open access: yesBiomedical Chromatography, Volume 40, Issue 2, February 2026.
ABSTRACT A stability‐indicating UHPLC–MS method was developed to investigate the stress degradation behavior of eletriptan hydrobromide under ICH‐recommended acidic, alkaline, neutral, oxidative, thermal, and photolytic conditions. Significant degradation was observed only under acidic and oxidative stress.
