Generalized Rainbow Connection of Graphs and their Complements
Discussiones Mathematicae Graph Theory, 2018 Let G be an edge-colored connected graph. A path P in G is called ℓ-rainbow if each subpath of length at most ℓ + 1 is rainbow. The graph G is called (k, ℓ)-rainbow connected if there is an edge-coloring such that every pair of distinct vertices of G is ...

Anti-Ramsey theory on complete bipartite graphs
AKCE International Journal of Graphs and Combinatorics, 2020 We consider quadruples of positive integers with and such that every proper edge-coloring of the complete bipartite graph contains a rainbow subgraph. We show that every such quadruple with and satisfies this property and find an infinite sequence where ...

Journal of Synchrotron Radiation, EarlyView.This work demonstrates that standard ARPES datasets often hinder correct comparison with band structure calculations due to intrinsic mixing of energy and momentum. It proposes an angle‐based approach that preserves true k‐space mapping, enabling more accurate and intuitive comparison with calculated electronic structures.Angle‐resolved photoemission ...

Chromatic Spectrum of $K_s$-WORM Colorings of $K_n$ [PDF]
Computer Science Journal of Moldova, 2020 An {\it $H$-WORM} coloring of a simple graph $G$ is the coloring of the vertices of $G$ such that no copy of $H\subseteq G$ is monochrome or rainbow. In a recently published article by one of the authors \cite{All1}, it was claimed that the number of $r$

Vertex rainbow colorings of graphs
Discussiones Mathematicae Graph Theory, 2012 In a properly vertex-colored graph G, a path P is a rainbow path if no two vertices of P have the same color, except possibly the two end-vertices of P. If every two vertices of G are connected by a rainbow path, then G is vertex rainbow-connected. A proper vertex coloring of a connected graph G that results in a vertex rainbow-connected graph is a ...

Molecular structure and nickel‐binding capacity of Proteus mirabilis UreE
Acta Crystallographica Section D, EarlyView.This study presents a 2.0 Å resolution crystal structure and determined the nickel‐binding capacity of the P. mirabilis nickel chaperone UreE. UreE is essential for the delivery of nickel to the metalloenzyme urease, which is key for the ability of P. mirabilis to cause urinary‐tract infections.UreE is a nickel chaperone that is required for the safe ...

Flap Anatomies and Victorian Veils: Penetrating the Female Reproductive Interior
Gender &History, EarlyView.ABSTRACT This article examines the reappearance in the early nineteenth century of anatomical flapbooks in the context of obstetrical education in Britain, America and France. It asks why liftable paper flaps were reintroduced at this time after their disappearance from medical atlases in the eighteenth century.

International Journal of Urban and Regional Research, EarlyView.Abstract The Beqaa Valley in Lebanon has become increasingly polluted, and residents are attributing illness to improper waste disposal and dumping. This article explores local epistemologies of pollution’s causes and effects in three films, which were researched and produced by local residents of Bar Elias, a small town in the Beqaa, which has rapidly
