Free subgroups with torsion quotients and profinite subgroups with torus quotients

open access: yesRendiconti del Seminario Matematico della Università di Padova, 2020
Here “group” means abelian group. Compact connected groups contain \delta -subgroups, that is, compact totally disconnected subgroups with torus quotients, which are essential ingredients in the important Resolution Theorem, a description of compact groups. Dually, full free subgroups of

VERMONT: Vessel Fractional Flow Reserve (vFFR) Assessment of Stenosis Severity: A Prospective Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Vessel fractional flow reserve (vFFR) is an angiogram‐based technique validated in early studies; however, data on its real‐time diagnostic performance and integration into routine workflow remain limited. Aims The VERMONT study evaluated the diagnostic accuracy and time efficiency of real‐time vFFR versus conventional wire‐based ...

Visual intraoperative estimation of cup and stem position is not reliable in minimally invasive hip arthroplasty

open access: yesActa Orthopaedica, 2016
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.

Curvature and torsion pseudotensors of coaffine connection in tangent bundle of hypercentred planes manifold

open access: yesДифференциальная геометрия многообразий фигур, 2020
The hypercentered planes family, whose dimension coincides with dimension of generating plane, is considered in the projective space. Two principal fiber bundles arise over it.

Dimensional reduction of higher derivative heterotic supergravity

open access: yesJournal of High Energy Physics, 2022
Higher derivative couplings of hypermultiplets to 6D, N = (1, 0) supergravity are obtained from dimensional reduction of 10D heterotic supergravity that includes order α′ higher derivative corrections.

Entropy in a category

open access: yes, 2011
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.

Phenotype characterization of heart failure with preserved ejection fraction in medical device and surgical trials

open access: yesESC Heart Failure, EarlyView.
This systematic review identified 24 clinical trials of medical device and surgical interventions for HFpEF, with 16 demonstrating at least safety and feasibility, but little evidence of long‐term benefit. Phenotype‐based responses suggest that certain interventions may benefit specific HFpEF subgroups, yet most trials suffered from heterogeneous ...

Distortion maps for supersingular genus two curves

open access: yesJournal of Mathematical Cryptology, 2009
Distortion maps are a useful tool for pairing based cryptography. Compared with elliptic curves, the case of hyperelliptic curves of genus g > 1 is more complicated, since the full torsion subgroup has rank 2g.
