Multiplicative Lie n-derivations of triangular rings
, 2012 We introduce the notion of a multiplicative Lie n-derivation of a ring, generalizing the notion of a Lie (triple) derivation. The main goal of the paper is to consider the question of when do all multiplicative Lie n-derivations of a triangular ring T ...

Complete blocked triangular matrix rings
, 1993 Thesis (M. Sc.) -- University of Stellenbosch, 1993.An exposition is given of a paper by M.S. Li and J.M. Zelmanowitz in which complete blocked triangular matrix rings over division rings are characterized by conditions analogous to those of the ...

Strongly clean triangular matrix rings with endomorphisms
, 2013 A ring $R$ is strongly clean provided that every element in $R$ is the sum of an idempotent and a unit that commutate. Let $T_n(R,σ)$ be the skew triangular matrix ring over a local ring $R$ where $σ$ is an endomorphism of $R$. We show that $T_2(R,σ)$ is strongly clean if and only if for any $a\in 1+J(R), b\in J(R)$, $l_a-r_{σ(b)}: R\to R$ is ...

Products of three triangular matrices over commutative rings
, 2002 We characterize commutative rings with 1 over which any n×n matrix A can be written as LUM, where L,M are lower triangular, U is upper triangular and L and U have all their diagonal entries ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells
Advanced Materials, EarlyView.This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Derivations of upper triangular matrix rings
Linear Algebra and its Applications, 1993 Let \(R\) be a ring with unity. The authors consider derivations of the ring \(T_ n(R)\), the ring of \(n\times n\) upper triangular matrices over \(R\). For a derivation \(d\) of \(R\), \(\overline{d}\) denotes the derivation that is induced by \(d\) on \(T_ n(R)\).

Advanced Materials, EarlyView.Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the
