Stellar dynamics and dark matter in Local Group dwarf galaxies
Nature Astronomy, 2022When interpreted within the standard framework of Newtonian gravity and dynamics, the kinematics of stars and gas in dwarf galaxies reveals that most of these systems are completely dominated by their dark matter halos.

Local Group Invariance for Heart Rate Estimation from Face Videos in the Wild
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2018We study the impact of prior knowledge about invariance for the task of heart rate estimation from face videos in the wild (e.g. in presence of disturbing factors like rigid head motion, talking, facial expressions and natural illumination conditions ...

The purpose of this note is to generalize a result of Gulliksen, Ribenboim and Viswanathan which characterized local group rings when both the ring and the group are commutative.We assume throughout that all rings are associative with identity. If R is a ring we call R local if R/J(R) is a division ring where J(R) denotes the Jacobson radical of R.

Summary: For any integer \(n\neq 0,1\), a group is said to be \(n\)-Bell if it satisfies the law \([x^n,y]=[x,y^n]\). In this paper we prove that every finitely generated locally graded \(n\)-Bell group embeds into the direct product of a finite \(n\)-Bell group and a torsion-free nilpotent group of class \(\leq 2\).

Locally compact transformation groups
Transactions of the American Mathematical Society, 1961In ?1 of this paper it is shown that a variety of conditions implying nice behavior for topological transformation groups are, in the presence of separability, equivalent. In ?2 the continuity properties of the stability subgroups are studied. The conditions of ?1 exclude the line acting on the torus in such a way that each orbit is dense. They exclude

Interconnection Locality and Group Locality
EUROCON 2005 - The International Conference on "Computer as a Tool", 2005The interconnection locality is the behavior of a network around the origin and it is firstly understood as neighborhood. The group locality, which we try to define in this paper, is another point of view on the networks locality, opposite, in some way, to the globality.
