σ-derivations on generalized matrix algebras
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020 Let be a commutative ring with unity, 𝒜, be -algebras, be (𝒜, )-bimodule and 𝒩 be (, 𝒜)-bimodule. The -algebra 𝒢 = 𝒢(𝒜, , 𝒩, ) is a generalized matrix algebra defined by the Morita context (𝒜, , , 𝒩, ξ𝒩, Ω𝒩).

Local triple derivations on real C*-algebras and JB*-triples [PDF]
, 2013 We study when a local triple derivation on a real JB*-triple is a triple derivation. We find an example of a (real linear) local triple derivation on a rank-one Cartan factor of type I which is not a triple derivation.

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)
The Anatomical Record, EarlyView.Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Higher Derivations on Lie Ideals
Trends in Computational and Applied Mathematics, 2002 In this paper we present a brief proof of a recently proved result [5, Corollary 1.4]. The main result states that if R is a prime ring of characteristic different of 2 and U is a Lie ideal of R where U 6½ Z(R), the center of R, u2 2 U for all u 2 U, and

Local triple derivations on C*-algebras [PDF]
, 2012 We prove that every bounded local triple derivation on a unital C*-algebra is a triple derivation.

The Anatomical Record, EarlyView.Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Odd and even derivations, transposed Poisson superalgebra and 3-Lie superalgebra [PDF]
Proceedings of the Estonian Academy of SciencesOne important example of a transposed Poisson algebra can be constructed by means of a commutative algebra and its derivation. This approach can be extended to superalgebras; that is, one can construct a transposed Poisson superalgebra given a ...

Triality Groups Associated with Triple Systems and their Homotope Algebras
Annales Mathematicae Silesianae, 2021 We introduce the notion of an (α, β, γ) triple system, which generalizes the familiar generalized Jordan triple system related to a construction of simple Lie algebras. We then discuss its realization by considering some bilinear algebras and vice versa.

Dental crown morphological variation and heterodonty in carcharhiniform sharks
The Anatomical Record, EarlyView.Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Jordan higher derivations revisited
Gulf Journal of Mathematics, 2014 In this note, we consider the question of when a Jordan higher derivation of an arbitrary ring degenerates to a higher derivation. Furthermore, several applications to specific rings or algebras are presented.
