Automorphisms of real Lie algebras of dimension five or less [PDF]
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.

Minimal Lorentz Surfaces in Pseudo-Euclidean 4-Space with Neutral Metric
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

Modelling and analysis of biochemical signalling pathway cross-talk [PDF]
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 ...

Why people use digital payments: Evidence from micro data in Peru
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]
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 $\mathbb{E}_1^3$

CBDC and Trust in A Central Bank: Transitivity Of Preferences Vs. The Privacy Paradox
The privacy and anonymity of transactions are considered some of the biggest challenges when designing Central Bank Digital Currencies (CBDC). While many surveys show that people strongly prefer privacy in their transactions, behavioral theories suggest ...

Fine group gradings of the real forms of $sl(4,\C)$, $sp(4,\C)$, and $o(4,\C)$
We present an explicit description of the 'fine group gradings' (i.e. group gradings which cannot be further refined) of the real forms of the semisimple Lie algebras $sl(4,\C)$, $sp(4,\C)$, and $o(4,\C)$. All together 12 real Lie algebras are considered,

Finite-Dimensional Representations of the Quantum Superalgebra U$_{q}$[gl(2/2)]: I. Typical representations at generic $q$ [PDF]
In the present paper we construct all typical finite-dimensional representations of the quantum Lie superalgebra $U_{q}[gl(2/2)]$ at generic deformation parameter $q$.

The Birds of the Highlands of South-West Saudi Arabia and adjacent parts of the Tihama: July 2010 [PDF]
The objective of the survey was to compare habitats and bird life in the Asir region, particularly Jebal Souda and the Raydah escarpment protected area of the Saudi Wildlife Commission, and adjacent regions of the tihama, with those observed in July 1987
