On the Total Double Roman Domination

open access: yesIEEE Access, 2019
Let G = (V, E) be a simple graph. A double Roman dominating function (DRDF) on G is a function f from the vertex set V of G into {0, 1, 2, 3} such that if f (u) = 0, then u must have at least two neighbors assigned 2 or one neighbor assigned 3 under f ...

Complexity of Roman {2}-domination and the double Roman domination in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
For a simple, undirected graph a Roman {2}-dominating function (R2DF) has the property that for every vertex with f(v) = 0, either there exists a vertex with f(u) = 2, or at least two vertices with The weight of an R2DF is the sum The minimum weight of ...

The ‘Pierre Duhem Thesis.’ A Reappraisal of Duhem’s Discovery of the Physics of the Middle Ages [PDF]

open access: yes, 2015
Pierre Duhem is the discoverer of the physics of the Middle Ages. The discovery that there existed a physics of the Middle Ages was a surprise primarily for Duhem himself.

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

open access: yesAngewandte Chemie, EarlyView.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.

Quasi total double Roman domination in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
A quasi total double Roman dominating function (QTDRD-function) on a graph [Formula: see text] is a function [Formula: see text] having the property that (i) if f(v) = 0, then vertex v must have at least two neighbors assigned 2 under f or one neighbor w

On the weak Roman domination number of lexicographic product graphs

open access: yes, 2018
A vertex $v$ of a graph $G=(V,E)$ is said to be undefended with respect to a function $f: V \longrightarrow \{0,1,2\}$ if $f(v)=0$ and $f(u)=0$ for every vertex $u$ adjacent to $v$.

Opiate of Christ; or, John's Gospel and the Spectre of Class [PDF]

open access: yes, 2016
This article applies a Libertarian Marxist lens to the Gospel of John. In doing so, it highlights the agrarian-aristocratic class struggle that is refracted in the text and also seeks to problematize hierarchi- cal and authoritarian ideologies. Its point

Strong Equality of Perfect Roman and Weak Roman Domination in Trees [PDF]

open access: yes, 2019
Let G=(V,E) be a graph and f:V⟶{0,1,2} be a function. Given a vertex u with f(u)=0, if all neighbors of u have zero weights, then u is called undefended with respect to f.
