Jordan Centralizer Maps on Trivial Extension Algebras
Demonstratio Mathematica, 2020 The structure of Jordan centralizer maps is investigated on trivial extension algebras. One may obtain some conditions under which a Jordan centralizer map on a trivial extension algebra is a centralizer map. As an application, we characterize the Jordan

Analysis of the effect of stabilizer configuration on reamer vibration suppression [PDF]
Science ProgressDownhole severe vibration of reamers while drilling is a critical bottleneck restricting drilling safety and efficiency. Existing studies often neglect the coupled effects of cutter dynamic wear on vibration and lack systematic quantitative analysis of ...

Design and In Vitro Validation of an Orthopaedic Drill Guide for Femoral Stem Revision in Total Hip Arthroplasty [PDF]
IEEE Journal of Translational Engineering in Health and MedicineObjective: Cemented total hip arthroplasty (THA) demonstrates superior survival rates compared to uncemented procedures. Nevertheless, most younger patients opt for uncemented THA, as removing well-fixed bone cement in the femur during revisions is ...

Numerical analysis on the centralization effect of improved horizontal well casing centralizer
Frontiers in Energy Research, 2023 Horizontal well technology is a promising method for oil and gas development. During cementing operations in horizontal wells, it was found that conventional casing centralizers could not meet the requirements for casing cementing in expanded wellbores ...

The structure of groups with cyclic commutator subgroups indecomposable to a subdirect product of groups [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021 The article studies finite groups indecomposable to subdirect product of groups (subdirectly irreducible groups), commutator subgroups of which are cyclic subgroups.

Quasi Centralizers and Inner Derivations in a Closed Ideal of a Complex Banach Algebra [PDF]
مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2004 In this paper we show that, for an ideal J of a unital complex Banach algebra A, we have (i) under certain conditions the ? -quasi centralizer, the quasi centralizer, and the centralizer of J are all identical, and so they are subsets of the ?

McKay Centralizer Algebras [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 For a finite subgroup G of the special unitary group SU2, we study the centralizer algebra Zk(G) = EndG(V⊗k) of G acting on the k-fold tensor product of its defining representation V = C2.

A note on Jordan left *-centralizers on prime and semiprime rings with involution
Journal of Taibah University for Science, 2017 The aim of this note is to give alternative and short proofs for some results to Ali et al. in [3] by using the relationship between the concepts of Jordan left *-centralizer and right centralizer on a 2-torsion free semiprime rings endowed with ...

ACENTRALIZERS OF GROUPS OF ORDER p3 [PDF]
Journal of Algebraic Systems, 2023 Suppose that $G$ is a finite group. The acentralizer $C_G(\alpha)$ of an automorphism $\alpha$ of $G$,is defined as the subgroup of fixed points of $\alpha$, that is $C_G(\alpha)= \{g \in G \mid \alpha(g)=g\}$.In this paper we determine the ...
