Chronic and acute mediators of passive viscoelasticity in human skeletal muscle fibres

open access: yesExperimental Physiology, Volume 110, Issue 12, Page 1948-1965, December 1, 2025.
Abstract The cellular viscoelastic modulus in skeletal muscle tissue responds dynamically to chronic stressors, such as age and exercise. Passive tissue mechanics can also be sensitive to acute stimuli, such as mechanical loading and/or activation‐induced muscle fatigue.

A-manifolds on a principal torus bundle over an almost Hodge A-manifold base

open access: yes, 2015
An A-manifold is a manifold whose Ricci tensor is cyclic-parallel, equivalently it satisfies ∇X Ric(X, X) = 0. This condition generalizes the Einstein condition.

Digital Platforms for Sustainable Development: Unveiling the Psychology of Green Food Choices

open access: yesCorporate Social Responsibility and Environmental Management, Volume 32, Issue 6, Page 8258-8279, November 2025.
ABSTRACT Digital platforms are reshaping consumer engagement with sustainable food, offering new cognitive, social, and technological contexts for green purchasing. This study explores the psychological mechanisms and social dynamics that drive green food purchase intentions in digital environments.

Локально ϕ-симетричні узагальнені форми простору Сасакяна

open access: yes, 2013
The aim of the present paper is to find necessary and sufficient conditions for locally ϕ-symmetric generalized Sasakian-space forms to have constant scalar curvature, η -parallel Ricci tensor, and cyclic parallel Ricci tensor.

A Study on Trans-para-Sasakian Manifolds

open access: yes
In the current paper, we make the first contribution to investigate conditions under which three-dimensional trans-para-Sasakian manifold has η-parallel Ricci tensor and cyclic parallel Ricci tensor.

Riemannian manifolds with Einstein-like metrics [PDF]

open access: yes, 1985
In this thesis, we investigate properties of manifolds with Riemannian metrics which satisfy conditions more general than those of Einstein metrics, including the latter as special cases. The Einstein condition is well known for being the Euler- Lagrange
