Friedmann-like universes with torsion [PDF]
The European Physical Journal C, 2018 We consider spatially homogeneous and isotropic cosmologies with non-zero torsion. Given the high symmetry of these universes, we adopt a specific form for the torsion tensor that preserves the homogeneity and isotropy of the spatial surfaces.

Newton-Cartan Gravity and Torsion [PDF]
, 2017 We compare the gauging of the Bargmann algebra, for the case of arbitrary torsion, with the result that one obtains from a null-reduction of General Relativity.

The stability of anisotropic cylindrical shells under torsion in spatial position [PDF]
Acta Scientiarum Polonorum. Architectura, 2020 In the present paper, an infinite system of homogeneous differential equations in the Cauchy normal form was obtained to solve the problem of the stability of cylindrical anisotropic layered shells under the action of external torque, based on the ...

Cosmological hyperfluids, torsion and non-metricity [PDF]
The European Physical Journal C, 2020 We develop a novel model for cosmological hyperfluids, that is fluids with intrinsic hypermomentum that induce spacetime torsion and non-metricity. Imposing the cosmological principle to metric-affine spaces, we present the most general covariant form of

Weighted Homology of Bi-Structures over Certain Discrete Valuation Rings
Mathematics, 2021 An RNA bi-structure is a pair of RNA secondary structures that are considered as arc-diagrams. We present a novel weighted homology theory for RNA bi-structures, which was obtained through the intersections of loops.

Multivariable Regression Strength Model for Steel Fiber-Reinforced Concrete Beams under Torsion
Materials, 2021 Torsional behavior and analysis of steel fiber reinforced concrete (SFRC) beams is investigated in this paper. The purpose of this study is twofold; to examine the torsion strength models for SFRC beams available in the literature and to address properly

Dyssynchronous Left Ventricular Activation is Insufficient for the Breakdown of Wringing Rotation
Frontiers in Physiology, 2022 Cardiac resynchronization therapy is a valuable tool to restore left ventricular function in patients experiencing dyssynchronous ventricular activation. However, the non-responder rate is still as high as 40%.
