On maximal Roman domination in graphs: complexity and algorithms
RAIRO Oper. Res.For a simple undirected connected graph G = (V,E), a maximal Roman dominating function (MRDF) of G is a function f : V (G) → {0,1,2} with the following properties: (i) For every vertex v ∈ {v ∈ V |f(v) = 0}, there exists a vertex u ∈ N(v) such that f(u) =

Advanced Energy Materials, EarlyView.Herein, by employing a reference electrode, the durability of anion exchange membrane water electrolyzer (AEMWE) under intermittent condition is demonstrated to be governed by the stability of the cathode catalyst. By encapsulating NiMo catalyst with carbon shells, the oxidation‐induced irreversible transformation to inactive hydroxide is prevented ...

Signed double Italian domination
AIMS Mathematics, 2023 A signed double Italian dominating function (SDIDF) on a graph $ G = (V, E) $ is a function $ f $ from $ V $ to $ \{-1, 1, 2, 3\} $, satisfying (ⅰ) $ \sum_{u\in N[v]}f(u)\ge1 $ for all $ v\in V $; (ⅱ) if $ f(v) = -1 $ for some $ v\in V $, then there ...

The Chemistry and Biology of the Tetrodotoxin Natural Product Family
Angewandte Chemie International Edition, Accepted Article.Tetrodotoxin is a neurotoxic marine alkaloid, first isolated in 1909 from pufferfish and named after the biological order tetraodontiformes. Since its structural elucidation in 1964, it has attracted the interest of synthetic organic chemists due to its exceptional polarity, complex architecture, and important biological activity.

The Distance Roman Domination Numbers of Graphs
Discussiones Mathematicae Graph Theory, 2013 Let k be a positive integer, and let G be a simple graph with vertex set V (G). A k-distance Roman dominating function on G is a labeling f : V (G) → {0, 1, 2} such that for every vertex with label 0, there is a vertex with label 2 at distance at most k ...

Restrained roman domination in graphs [PDF]
Transactions on Combinatorics, 2015 A Roman dominating function (RDF) on a graph G = (V,E) is defined to be a function satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 2. A set S V is a Restrained dominating set if every

A Multifaceted Spatial Analysis of Tomb Distribution in Blemmyan Berenike (Eastern Desert of Egypt)
Archaeological Prospection, EarlyView.ABSTRACT This study examines the spatial and visual organisation of tombs in the post–Roman Berenike located in Egypt's Eastern Desert. Archaeological surveys, remote sensing, geophysical methods, excavations and GIS‐based analyses are used for a comprehensive understanding of the spatial patterns and cultural significance behind the positions and ...
