Additive Jordan derivations of reflexive algebras
Journal of Mathematical Analysis and Applications, 2007 AbstractAdditive Jordan derivations of certain reflexive algebras are investigated. In particular, additive Jordan derivations of nest algebras on Banach spaces are shown to be additive derivations.

Macrocycles of Saxitoxin: Insights into the Structure of Zetekitoxin AB
ChemBioChem, EarlyView.Synthetic macrocycles of (+)‐saxitoxin, the causative agent of paralytic shellfish poisoning, have been prepared. These are designed to mimic the macrocyclic core of the proposed structure for zetekitoxin AB. Interestingly, these synthetic macrocycles do not form the C12 hydrate as commonly observed in this family of toxins, casting doubt on the ...

Some conditions under which Jordan derivations are zero
Journal of Taibah University for Science, 2017 In the current article, we obtain the following results: Let A be an algebra and P be a semi-prime ideal of A. Suppose that d:Aâ(A/P) is a Jordan derivation such that dim{d(a)|aâA}â¤1. If d(P)={0}, then d is zero.

Commuting Jordan derivations over a Ring with idempotents [PDF]
arXivThis paper explores the behaviour of commuting Jordan derivations over prime rings with non-trivial idempotents and demonstrates that they become zero maps. Further, it establishes this result for commuting Jordan higher derivations over prime rings under specific conditions.

Left derivable or Jordan left derivable mappings on Banach algebras [PDF]
arXiv, 2015 Let d be a linear mapping from a unital Banach algebra A into a unital left A-module M, and w in Z(A) be a left separating point of M. We show that the following three conditions are equivalent: (i) d is a Jordan left derivation; (ii) d is left derivable at w; (iii) d is Jordan left derivable at w. Let A be a Banach algebra with the property (B), and M

ChemBioChem, Accepted Article.Aromatic ring flips are a hallmark of protein dynamics. They are mediated by either transient “breathing” motions in which the protein expands into the solvent or by transient internal rearrangement of void spaces. Therefore, they are excellent reporters of such transient protein fluctuations.

On Jordan superderivations and Jordan super-biderivations of trivial extensions and triangular matrix rings [PDF]
arXivTriangular matrix rings are example of trivial extensions. In this article we describe the Jordan superderivations of the trivial extensions and upper triangular matrix rings. We deduce then that any Jordan superderivation of an upper triangular matrix ring, under some conditions, is a derivation, and any Jordan super-biderivation of a trivial ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Studies on the relationship between board diversity and CSR disclosure have shown mixed results. This study investigates the relationship between board diversity attributes and CSR disclosure, as well as the various cultural conditions influencing board diversity–CSR disclosure relationships through meta‐analysis based on data from 45 ...
