Minimum distances of error‐correcting codes in incidence rings
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 13, Page 827-833, 2003., 2003 The main theorem of this paper gives a formula for the largest minimum distance of error‐correcting codes considered as ideals in incidence rings defined by directed graphs.

Isomorphism of generalized triangular matrix‐rings and recovery of tiles
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 9, Page 533-538, 2003., 2003 We prove an isomorphism theorem for generalized triangular matrix‐rings, over rings having only the idempotents 0and 1, in particular, over indecomposable commutative rings or over local rings (not necessarily commutative). As a consequence, we obtain a recovery result for the tile in a tiled matrix‐ring.

Veterinary Dermatology, Volume 35, Issue 4, Page 418-431, August 2024.Background – Diagnosis of canine adverse food reactions (AFRs) is based on vague criteria, such as ‘>50% improvement’ during elimination diet trial (EDT) followed by ‘deterioration’ during provocation test (PT). Objective – The objective of the study was to use predefined criteria to evaluate response during EDT [i.e., Owner Global Assessment of ...

Tilting Modules Under Special Base Changes
, 2018 Given a non-unit, non-zero-divisor, central element $x$ of a ring $\Lambda$, it is well known that many properties or invariants of $\Lambda$ determine, and are determined by, those of $\Lambda / x \Lambda$ and $\Lambda_x$.

Characterizing Jordan derivations of matrix rings through zero products [PDF]
, 2013 Let $\Mn$ be the ring of all $n \times n$ matrices over a unital ring $\mathcal{R}$, let $\mathcal{M}$ be a 2-torsion free unital $\Mn$-bimodule and let $D:\Mn\rightarrow \mathcal{M}$ be an additive map. We prove that if $D(\A)\B+ \A D(\B)+D(\B)\A+ \B D(\

Prime Structures in a Morita Context
, 2018 In this paper, we study on the primeness and semiprimeness of a Morita context related to the rings and modules. Necessary and sufficient conditions are investigated for an ideal of a Morita context to be a prime ideal and a semiprime ideal.
