Goldie's Theorem for Alternative Rings [PDF]
Proceedings of the American Mathematical Society, 1994 It is known that the socle of a semiprime Goldie ring is generated by a central idempotent and that a prime Goldie ring with a nonzero socle is a simple artinian ring. We prove the extension of these results to alternative rings. We also give an analogue of Goldie’s theorem for alternative rings.

Veronese representation of projective Hjelmslev planes over some quadratic alternative algebras [PDF]
, 2020 We geometrically characterise the Veronese representations of ring projective planes over algebras which are analogues of the dual numbers, giving rise to projective Hjelmslev planes of level 2 coordinatised over quadratic alternative algebras.

Fretting Characteristics of Rubber X-Ring Exposed to High-Pressure Gaseous Hydrogen
Energies, 2022 The rubber ring is an essential component of high-pressure hydrogen storage systems. However, the fretting damage can lead to the seal failure of the rubber ring, which may cause hydrogen leakage.

Scaffold searching: automated identification of similar ring systems for the design of combinatorial libraries [PDF]
, 2003 Rigid ring systems can be used to position receptor-binding functional groups in 3D space and they thus play an increasingly important role in the design of combinatorial libraries.

Currents and pseudomagnetic fields in strained graphene rings [PDF]
, 2013 We study the effects of strain on the electronic properties and persistent current characteristics of a graphene ring using the Dirac representation. For a slightly deformed graphene ring flake, one obtains sizable pseudomagnetic (gauge) fields that may ...

Pseudo-ring tests resolution for dynamic single faults in word-oriented memory
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2018 This paper presents single dynamic faults and methods for their detection. Such dynamic faults as dRDF, dDRDF and dIRF are considered in detail. Also, pseudo-ring testing and the principles of single dynamic faults detecting by pseudo-ring tests are ...

Blocking-cyclization technique for precise synthesis of cyclic polymers with regulated topology
Nature Communications, 2018 Cyclic polymers can be usually accessed by ring-expansion and ring-closure approaches. Here, the authors report an alternative blocking-cyclization technique which enables the tunable synthesis of multicyclic polymers via commercial Ru-based Grubbs ...

Ternary Generalized Jordan Ring Homomorphisms on Ternary Non-Archimedean Banach Algebras [PDF]
Sahand Communications in Mathematical AnalysisIn this paper, we introduce the notion of the ternary generalized Jordan ring homomorphism on ternary non-Archimedean Banach algebras. Utilizing alternative fixed point methods, we establish the generalized Hyers-Ulam stability of ternary generalized ...
