Groups Factorized by Pairwise Permutable Abelian Subgroups of Finite Rank [PDF]
It is proved that a group which is the product of pairwise permutable abelian subgroups of finite Prüfer rank is hyperabelian with finite Prüfer rank; in the periodic case the Sylow subgroups of such a product are described.

Introduction and objectives: Accurate measurement of femoral torsion is essential to diagnosing, correct surgical decision-making, and the preoperative planning of derotational osteotomies in a subgroup of anterior knee pain patients and patellofemoral ...

General relativity as a biconformal gauge theory
We consider the conformal group of a space of dimn=p+q, with SO(p,q) metric. The quotient of this group by its homogeneous Weyl subgroup gives a principal fiber bundle with 2n-dim base manifold and Weyl fibers.

A note on torsion-free locally cyclic quasinormal subgroups [PDF]
A subgroup \(H\) of a group \(G\) is said to be \textit{quasinormal} if \(HX=XH\) for all subgroups \(X\) of \(G\). A well-known theorem by \textit{R. Maier} and \textit{P. Schmid} [Math. Z. 131, 269-272 (1973; Zbl 0259.20017)] shows that every core-free quasinormal subgroup of a finite group \(G\) lies in the hypercentre of \(G\). This result fails to

Structure of Finite-Dimensional Protori
A Structure Theorem for Protori is derived for the category of finite-dimensional protori (compact connected abelian groups), which details the interplay between the properties of density, discreteness, torsion, and divisibility within a finite ...

Objectives To assess the feasibility of flexion-abduction-external rotation (FABER) magnetic resonance imaging (MRI) of the hip to visualize changes in the ischiofemoral interval and ability to provoke foveal excursion over the acetabular rim.

The Pinsker subgroup of an abelian group with respect to an endomorphism was introduced in the context of algebraic entropy. Motivated by the nice properties and characterizations of the Pinsker subgroup, we generalize its construction in two directions.

Background and purpose — In hip arthroplasty, acetabular inclination and anteversion—and also femoral stem torsion—are generally assessed by eye intraoperatively. We assessed whether visual estimation of cup and stem position is reliable.
