Impact of Some Graph Operations on Double Roman Domination Number
, 2019 Given a graph $G=(V,E)$, a function $f:V\rightarrow \{0,1,2,3\}$ having the property that if $f(v)=0$, then there exist $ v_{1},v_{2}\in N(v)$ such that $f(v_{1})=f(v_{2})=2$ or there exists $ w \in N(v)$ such that $f(w)=3$, and if $f(v)=1$, then there exists $ w \in N(v)$ such that $f(w)\geq 2$ is called a double Roman dominating function (DRDF).

Food Safety and Health, EarlyView.Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Notes on double Roman domination edge critical graphs [PDF]
Given a graph G = (V, E), a double Roman dominating function (DRDF) on a graph G is a function f : V → {0, 1, 2, 3} satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 3 or two vertices v1

International Journal of Gynecology &Obstetrics, EarlyView.Abstract Objectives Spontaneous premature ovarian insufficiency (POI) is a condition characterized by the cessation of ovarian function before age 40, unrelated to medical interventions. It affects approximately 3.5% of women worldwide and can result in significant emotional, physical, and social consequences.

Upper Bounds for Double Roman Domination and [k]-Roman Domination of Cylindrical Graphs Cm☐Pn
AxiomsRoman-type domination parameters form an important class of graph invariants that model protection and resource allocation problems on networks. Among them, [k]-Roman domination provides a unified framework that generalizes Roman, double Roman, and ...

Psychological Contracts With Purpose: A Review and Path Forward
Journal of Organizational Behavior, EarlyView.ABSTRACT This review advances the understanding of psychological contracts (PCs) that include third‐party beneficiaries and transcend self‐interested goals, which we term “PCs with purpose.” PC theory has challenged the assumption that social exchange relies solely on balanced rewards and inducements, highlighting that individuals may wish to ...
