Automorphisms of real Lie algebras of dimension five or less [PDF]
, 2013 The Lie algebra version of the Krull-Schmidt Theorem is formulated and proved. This leads to a method for constructing the automorphisms of a direct sum of Lie algebras from the automorphisms of its indecomposable components.

The Chandra view of the 3C/FRI sample of low luminosity radio-galaxies [PDF]
, 2006 We present results from Chandra observations of the 3C/FRI sample of low luminosity radio-galaxies. We detected a power-law nuclear component in 12 objects out of the 18 with available data.

Quasi-minimal Lorentz Surfaces with Pointwise 1-type Gauss Map in Pseudo-Euclidean 4-Space
, 2015 A Lorentz surface in the four-dimensional pseudo-Euclidean space with neutral metric is called quasi-minimal if its mean curvature vector is lightlike at each point.

Jordanian Quantum Algebra ${\cal U}_{\sf h}(sl(N))$ via Contraction Method and Mapping [PDF]
, 2001 Using the contraction procedure introduced by us in Ref. \cite{ACC2}, we construct, in the first part of the present letter, the Jordanian quantum Hopf algebra ${\cal U}_{\sf h}(sl(3))$ which has a remarkably simple coalgebraic structure and contains the

Modelling and analysis of biochemical signalling pathway cross-talk [PDF]
, 2010 Signalling pathways are abstractions that help life scientists structure the coordination of cellular activity. Cross-talk between pathways accounts for many of the complex behaviours exhibited by signalling pathways and is often critical in producing ...

Minimal Lorentz Surfaces in Pseudo-Euclidean 4-Space with Neutral Metric
, 2018 We study minimal Lorentz surfaces in the pseudo-Euclidean 4-space with neutral metric whose first normal space is two-dimensional and whose Gauss curvature $K$ and normal curvature $\varkappa$ satisfy the inequality $K^2-\varkappa^2 >0$. Such surfaces we

ALL THAT GLITTERS: THE MANY OBJECTS OF ROME'S MUSEUM OF CIVILIZATIONS
History and Theory, EarlyView.ABSTRACT This review article examines the various methodologies practiced by Rome's Museum of Civilizations (Museo delle Civiltà ) to discuss the contemporary curatorial approaches of traditional ethnographic museums. It adopts a historical and comparative perspective to situate the diverse collections within ongoing debates about art restitution.

Why people use digital payments: Evidence from micro data in Peru
Latin American Journal of Central Banking, 2021 Financial inclusion and digital payment use remain low in Peru. There is extensive literature on the determinants of deposit account access as a measure of financial inclusion, but few studies focus on digital payment use, and none addresses the Peru ...

Timelike Bertrand Curves in Semi-Euclidean Space [PDF]
, 2010 In this paper, it is proved that, no special timelike Frenet curve is a Bertrand curve in $\mathbb{E}_2^4$ and also, in $\mathbb{E}_\nu^{n+1}$ $ ({n \ge 3})$, such that the notion of Bertrand curve is definite only in $\mathbb{E}_1^2$ and $\mathbb{E}_1^3$
