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.

Optically Levitated Nanodumbbell Torsion Balance and GHz Nanomechanical Rotor. [PDF]
Physical Review Letters, 2018 Levitated optomechanics has great potential in precision measurements, thermodynamics, macroscopic quantum mechanics, and quantum sensing. Here we synthesize and optically levitate silica nanodumbbells in high vacuum.

Improved side-chain torsion potentials for the Amber ff99SB protein force field
Proteins: Structure, Function, and Bioinformatics, 2010 Recent advances in hardware and software have enabled increasingly long molecular dynamics (MD) simulations of biomolecules, exposing certain limitations in the accuracy of the force fields used for such simulations and spurring efforts to refine these ...

Analytic torsion and Reidemeister torsion [PDF]
Proceedings of the National Academy of Sciences, 1977 We announce a proof of the conjecture of Ray and Singer that for a compact Riemannian manifold the analytic torsion and Reidemeister torsion are equal. The proof involves studying the heat equation for certain manifolds M, equipped with metrics g u , 0 < u

Testicular Torsion in the Emergency Room: A Review of Detection and Management Strategies
Open Access Emergency Medicine, 2020 Testicular torsion is a challenging and time-sensitive diagnosis that is encountered frequently in daily practice, especially in the emergency room. A thorough history, the presence of a painful and swollen testis and testicular ultrasonography plays a ...

Comparison of the refined analytic and the Burghelea-Haller torsions [PDF]
, 2007 The refined analytic torsion associated to a flat vector bundle over a closed odd-dimensional manifold canonically defines a quadratic form $\tau$ on the determinant line of the cohomology.

Torsion of the undescended testis in a healthy adult male [PDF]
Srpski Arhiv za Celokupno LekarstvoIntroduction. Torsion of undescended testis (UDT) in adults is rare, with only several published cases so far, and represents a urological emergency. Case outlines. We present a case of UDT torsion in 31-year-old, otherwise healthy, man who had rightside

Journal of Engineering and Sustainable Development, 2020 Researches concerning internal torsional strengthening of box beams are very little, since few researchers may study such method of strengthening. This research adopts employing of internal Framed Steel Stiffening Ribs (FSSRs) to strengthen reinforced ...

Gravitational field around a screwed superconducting cosmic string in scalar-tensor theories [PDF]
, 2001 We obtain the solution that corresponds to a screwed superconducting cosmic string (SSCS) in the framework of a general scalar-tensor theory including torsion.
