Locally compact groups and locally minimal group topologies

Fundamenta Mathematicae, 2019
Summary: Minimal groups are Hausdorff topological groups \(G\) satisfying the open mapping theorem with respect to continuous isomorphisms, i.e., every continuous isomorphism \(G\rightarrow H\), with \(H\) a Hausdorff topological group, is a topological isomorphism.

The chemistry of the most metal-rich damped Lyman α systems at z ∼ 2 – II. Context with the Local Group [PDF]

, 2015
Using our sample of the most metal-rich damped Lyman $\alpha$ systems (DLAs) at z$\sim2$, and two literature compilations of chemical abundances in 341 DLAs and 2818 stars, we present an analysis of the chemical composition of DLAs in the context of the ...

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Line-of-Sight Mass Estimator and the Masses of the Milky Way and Andromeda Galaxy

Universe
The total mass of a galaxy group, such as the Milky Way (MW) and the Andromeda Galaxy (M 31), is typically determined from the kinematics of satellites within their virial zones. Bahcall and Tremaine (1981) proposed the v2r estimator as an alternative to

Cotton leaf segmentation with composite backbone architecture combining convolution and attention

Frontiers in Plant Science, 2023
Plant leaf segmentation, especially leaf edge accurate recognition, is the data support for automatically measuring plant phenotypic parameters. However, adjusting the backbone in the current cutting-edge segmentation model for cotton leaf segmentation ...

SENSITIVE 21 cm OBSERVATIONS OF NEUTRAL HYDROGEN IN THE LOCAL GROUP NEAR M31 [PDF]

, 2015
Very sensitive 21 cm H i measurements have been made at several locations around the Local Group galaxy M31 using the Green Bank Telescope at an angular resolution of 9.′1, with a 5σ detection level of NH i = 3.9 × 1017 cm−2 for a 30 km s−1 line. Most of

Probing the kinematics of the Local Group with chemically enriched gas in the HESTIA simulations

Astronomy & Astrophysics
We present a study of the gas kinematics within the HESTIA project, a state-of-the-art set of simulations of the Local Group, with a particular focus on the velocity patterns of different ions and the large-scale motion of gas and galaxies towards the ...

The Tidal Evolution of Local Group Dwarf Spheroidals

, 2007
(Abridged) We use N-body simulations to study the evolution of dwarf spheroidal galaxies (dSphs) driven by galactic tides. We adopt a cosmologically-motivated model where dSphs are approximated by a King model embedded within an NFW halo.

Local uncertainty inequalities for locally compact groups [PDF]

Transactions of the American Mathematical Society, 1988
Let G G be a locally compact unimodular group equipped with Haar measure m m , G ^ \hat G its unitary dual and μ \mu the Plancherel measure (or something closely akin to it) on G ^ \hat G . When
