Jordan derivations revisited

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 2005
Let d be a Jordan derivation from a ring A into an A-bimodule M. Our main result shows that the restriction of d to the ideal of A generated by certain higher commutators of A is a derivation. This general statement is used for proving that under various additional conditions d must be a derivation on A.

Rethinking Chlorine: Essential Chemical or Replaceable Risk?

open access: yesChemSusChem, EarlyView.
Chlorine is essential for the production of plastics and pharmaceuticals but poses significant safety and environmental risks. Herein, processes are presented that substitute chlorine or reduce its demand. Where indispensable, trichloride‐ and bichloride‐based ionic liquids could enhance safety and streamline the integration of renewable energy ...

(,)- Strongly Derivations Pairs on Rings

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2016
        Let R be an associative ring. In this paper we present the definition of (s,t)- Strongly derivation pair and Jordan (s,t)- strongly derivation pair on a ring R, and study the relation between them.

Recent Green and Sustainable Pd‐Catalyzed Aminations

open access: yesChemSusChem, Accepted Article.
Pd‐catalyzed aminations, while a powerful and commonly employed method of C‐N bond construction, often relies on unsustainable technologies that utilize: egregious organic solvents, high temperatures, long reaction times, and high catalyst loadings, especially of palladium.

Longitudinal monitoring of class‐switched memory‐B cell proportions identifies plausible germinal center failure in patients with suspected immune disorders

open access: yesCytometry Part B: Clinical Cytometry, EarlyView.
Abstract A reduced proportion of peripheral class‐switched memory B cells (CSM‐B cells) is presumed to indicate ineffective germinal activity. The extent that this finding corresponds to a plausible germinal center failure pathophysiology in patients not diagnosed with CVID or hyper IgM syndrome is not known.

Generalized Jordan derivations of unital algebras [PDF]

open access: yesarXiv
Let $A$ be a unital algebra over a field $F$ with $\operatorname*{char} (F)\neq2$. In this paper we introduce a new concept of a generalized Jordan derivation, covering Jordan centralizers and Jordan derivations, as follows: a linear map $f:A\rightarrow A$ is a generalized Jordan derivation if there exist linear maps $g;h:A\rightarrow A$ such that $f ...

Smithian–Spathian carbonate geochemistry in the northern Thaynes Group influenced by multiple styles of diagenesis

open access: yesThe Depositional Record, Volume 11, Issue 2, Page 616-636, April 2025.
While the Smithian–Spathian boundary carbon isotopic excursion has been traditionally interpreted as capturing global carbon cycle behaviour, recent studies have suggested that at least some Early Triassic carbon isotopic excursions may incorporate influences from authigenic or early diagenetic processes.
