Identities with Skew Derivations [PDF]
, 2000 We solve affirmatively a problem, raised by Kharchenko, on identities with compositions of skew derivations: We define the notion of trivial identities with compositions of skew derivations, which is unique in a certain sense.

Reverse derivations and generalized reverse derivations in semirings [PDF]
, 2023 In this article we extend the results on reverse derivation in rings to semirings. First we dispose of reverse derivations in prime semirings analogous to Herstein's result [7].

Remarks on second-order quadratic systems in algebras
Electronic Journal of Differential Equations, 2017 This paper is an addendum to our earlier paper [8], where a systematic study of quadratic systems of second order ordinary differential equations defined in commutative algebras was presented.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background General pediatricians often evaluate hematologic and oncologic presentations before subspecialty consultation, yet the 2025 Accreditation Council for Graduate Medical Education (ACGME) pediatric requirements reduce inpatient pediatric hematology/oncology (PHO) time, raising questions about resident readiness.

f-DERIVATIONS AND (f; g)-DERIVATIONS OF MV -ALGEBRAS [PDF]
, 2013 Recently, the algebraic theory of MV -algebras is intensively studied. In this paper, we extend the concept of derivation of $MV$-algebras and we give someillustrative examples.

Metrics for investigations into L2 knowledge of derivational affixes
Vocabulary Learning and InstructionKnowledge of derivational affixes makes an important contribution to second language learners' success when reading. Yet while the effects of some learner variables (L2 proficiency, L1 background) have been investigated, there has been little research ...

Notes on Semiprime Ideals with Symmetric Bi-Derivation
AxiomsIn this paper, we prove many algebraic identities that include symmetric bi-derivation in rings which contain a semiprime ideal. We intend to generalize previous results obtained for semiprime rings with symmetric derivation using semiprime ideals in ...
