Archaeological Prospection, EarlyView.ABSTRACT The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small ...

On the Gauss Map of Surfaces of Revolution with Nonlightlike Axis in Minkowski 3-Space
Abstract and Applied Analysis, 2014 We study surfaces of revolution with a nonlightlike axis in 3-dimensional Minkowski space and classify such surfaces in terms of the Gauss map G that satisfies the condition ΔhG=ΛG, with Λ being a 3×3 real matrix.

Batteries &Supercaps, EarlyView.This study presents the synthesis of an anthraquinone oligomer linked by amide bonds that demonstrate a long cycle battery performance. Oligomers connected by amide bonds undergo hydrolysis, rendering them easily biodegradable. The concept provides a guideline for a future material design of sustainable batteries. With the increasing demand for energy,

Convex Combinations of Minimal Graphs
International Journal of Mathematics and Mathematical Sciences, 2012 Given a collection of minimal graphs, 𝑀1,𝑀2,…,𝑀𝑛, with isothermal parametrizations in terms of the Gauss map and height differential, we give sufficient conditions on 𝑀1,𝑀2,…,𝑀𝑛 so that a convex combination of them will be a minimal graph.

Quantum groups, Yang–Baxter maps and quasi-determinants
Nuclear Physics B, 2018 For any quasi-triangular Hopf algebra, there exists the universal R-matrix, which satisfies the Yang–Baxter equation. It is known that the adjoint action of the universal R-matrix on the elements of the tensor square of the algebra constitutes a quantum ...

ChemistryEurope, EarlyView.Reacting Bis2GaBr (Bis = CH(SiMe3)2) with Bis2AlH selectively yields Bis2GaH, a monomeric hydride in solution, characterized by diffusion ordered spectroscopy NMR, infrared spectroscopy and indirectly via hydrogallation. A one‐pot route enables frustrated Lewis pairs Bis2EOPtBu2 (E = Al, Ga), with the gallium analog splitting H2 and showing a dynamic ...

Planar and Pyramidal Pentacoordinate Selenium Atoms
Chemistry – A European Journal, EarlyView.Planar (D5h) and pyramidal (C5v) dianionic clusters, SeM5X52− (M = LiK; X = FBr), showcase pentacoordinate selenium atoms stabilized by geometric confinement and electrostatic interactions with surrounding alkali and halogen atoms. Abstract A systematic computational exploration of the dianionic systems SeM5X52− (M = Li─Cs; X = F─I) was conducted to ...

Dimer models and conformal structures
Communications on Pure and Applied Mathematics, EarlyView.Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

A special case of rational θs for terminating θ-expansions [PDF]
Surveys in Mathematics and its Applications, 2013 There have been quite a few generalizations of the usual continued fraction expansions over the last few years. One very special generalization deals with θ-continued fraction expansions or simply θ-expansions introduced by Bhattacharya and Goswami [A ...
