Non-minimal bridge positions of torus knots are stabilized

, 2010
We show that any non-minimal bridge decomposition of a torus knot is stabilized and that $n$-bridge decompositions of a torus knot are unique for any integer $n$. This implies that a knot in a bridge position is a torus knot if and only if there exists a

T-Duality via Gerby Geometry and Reductions [PDF]

, 2015
We consider topological T-duality of torus bundles equipped with S^{1}-gerbes. We show how a geometry on the gerbe determines a reduction of its band to the subsheaf of S^{1}-valued functions which are constant along the torus fibres.

A Novel Ground Distance Protection Algorithm for Non-Uniform Power Transmission Lines

Energies
In this paper, the performance of a conventional distance protection relay employing a single ground compensation factor (k0) per protection zone is investigated for non-uniform transmission lines consisting of mixed overhead line and underground cable ...

Gravitational potential of a homogeneous circular torus: new approach

, 2012
The integral expression for gravitational potential of a homogeneous circular torus composed of infinitely thin rings is obtained. Approximate expressions for torus potential in the outer and inner regions are found. In the outer region a torus potential

The dust covering factor in active galactic nuclei [PDF]

, 2016
The primary source of emission of active galactic nuclei (AGNs), the accretion disc, is surrounded by an optically and geometrically thick dusty structure ('the so-called dusty torus').

Epidemiologic evaluation of torus fractures of radius in Turkey and comparison of different immobilization modalities

Medicine Science, 2022
Torus fracture of the distal radius is one of the most common pediatric fractures. Though inherently stable, the literature lacks data about the complications or refracture rates after these fractures.

The Tubby Torus as a Quotient Group

Axioms, 2020
Let E be any metrizable nuclear locally convex space and E ^ the Pontryagin dual group of E. Then the topological group E ^ has the tubby torus (that is, the countably infinite product of copies of the circle group) as a quotient group if

Symplectic torus actions with coisotropic principal orbits [PDF]

, 2006
In this paper we completely classify symplectic actions of a torus $T$ on a compact connected symplectic manifold $(M, \sigma)$ when some, hence every, principal orbit is a coisotropic submanifold of $(M, \sigma)$. That is, we construct an explicit model,
