Triangular Regions Representations for Matching Images With Viewpoint Changes
IEEE Access, 2022 This paper proposes triangular region representations based on keypoints detected in images with viewpoint changes. The strongest keypoints in the reference and query images are allocated individually using a previously published contourlet-based ...

Triangular matrix representations of ring extensions
Journal of Algebra, 2003 AbstractIn this paper we investigate the class of piecewise prime, PWP, rings which properly includes all piecewise domains (hence all right hereditary rings which are semiprimary or right Noetherian). For a PWP ring we determine a large class of ring extensions which have a generalized triangular matrix representation for which the diagonal rings are ...

Universal Proteomic Signature After Exercise‐Induced Muscle Injury in Muscular Dystrophies
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Several neuromuscular disorders (NMDs) are characterized by progressive muscle damage and are marked by the elevation of circulating muscle proteins from activity‐related injury. Despite a diverse array of genetic drivers, many NMDs share similar patterns of exercise intolerance and higher concentrations of muscle injury proteins ...

Bounds for the norm of lower triangular matrices on the Cesàro weighted sequence space
Journal of Inequalities and Applications, 2017 This paper is concerned with the problem of finding bounds for the norm of lower triangular matrix operators from l p ( w ) $l_{p}(w)$ into c p ( w ) $c_{p} (w)$ , where c p ( w ) $c_{p}(w)$ is the Cesàro weighted sequence space and ( w n ) $(w_{n})$ is ...

Images of linear polynomials on upper triangular matrix algebras [PDF]
arXiv, 2023 The Fagundes-Mello conjecture asserts that every multilinear polynomial on upper triangular matrix algebras is a vector space, which is an improtant variation of the old and famous Lvov-Kaplansky conjecture. The goal of the paper is to give a description of the images of linear polynomials with zero constant term on the upper triangular matrix algebra ...

Some extensions of right N-semilocal rings
Journal of Scientific Research in ScienceIn this paper, we study the necessary and sufficient conditions for the formal triangular matrix ring, the generalized upper triangular matrix ring, the trivial Morita context, and the Morita context to be right N-semilocal, right N-semiperfect, right N ...

Triangular Decomposition of Matrices in a Domain [PDF]
Computer Algebra in Scientific Computing. LNCS 9301, Springer,
Switzerland, 2015, P.290-304, 2017 Deterministic recursive algorithms for the computation of matrix triangular decompositions with permutations like LU and Bruhat decomposition are presented for the case of commutative domains. This decomposition can be considered as a generalization of LU and Bruhat decompositions, because they both may be easily obtained from this triangular ...
