A Groupoid Approach to Discrete Inverse Semigroup Algebras [PDF]
, 2009 Let $K$ be a commutative ring with unit and $S$ an inverse semigroup. We show that the semigroup algebra $KS$ can be described as a convolution algebra of functions on the universal \'etale groupoid associated to $S$ by Paterson.

International Journal of Distributed Sensor Networks, 2022 As the most important segment of the spindle unit angular contact ball bearing, the preload significantly influences the bearing characteristics. Thus, the thermal-induced preload derived from the thermal expansion of spindle unit components also affects

The almost isomorphism relation for simple regular rings [PDF]
, 1992 A longstanding open problem in the theory of von Neumann regular rings is the question of whether every directly finite simple regular ring must be unit-regular. Recent work on this problem has been done by P. Menal, K.C . O'Meara, and the authors.

Additive unit structure of endomorphism rings and invariance of modules [PDF]
, 2016 We use the type theory for rings of operators due to Kaplansky to describe the structure of modules that are invariant under automorphisms of their injective envelopes. Also, we highlight the importance of Boolean rings in the study of such modules. As a

Complex fermatean neutrosophic graph and application to decision making
Decision Making: Applications in Management and Engineering, 2023 A new growing area of neutrosophic set (NS) theory called complex neutrosophic sets (CNS) provides useful tools for dealing with uncertainty in complex valued physical variables that are observed in the actual world.

Novel Miniaturized Equal/Unequal HMSIW Filtering Power Dividers Based on the Evanescent Mode Technique [PDF]
Radioengineering, 2021 In this paper, three miniaturized equal/unequal filtering power dividers (FPDs) applying the half-mode substrate integrated waveguide (HMSIW) and metamaterial concepts are offered. The operational method of the presented structures is based on the theory

Crystal structure and DFT study of (E)-N-[2-(1H-indol-3-yl)ethyl]-1-(anthracen-9-yl)methanimine
Acta Crystallographica Section E: Crystallographic Communications, 2017 The title compound, C25H20N2, (I), was synthesized from the condensation reaction of anthracene-9-carbaldehyde and tryptamine in dry ethanol. The indole ring system (r.m.s.

Plasmon-induced transparency in ring-bar meta-atom
AIP Advances, 2018 We introduce an approach for constructing a scalable metamaterial structure, which is composed of a ring and a bar in a unit cell, and supports singular plasmon-induced transparency. The composite multilayered structure consists of coupled meta-atom with
