Acyclic domination [PDF]

open access: yes, 1988
summary:For a graphical property $\mathcal{P}$ and a graph $G$, a subset $S$ of vertices of $G$ is a $\mathcal{P}$-set if the subgraph induced by $S$ has the property $\mathcal{P}$. The domination number with respect to the property $\mathcal{P}$, is the

On domination in graphs [PDF]

open access: yes, 2005
For a finite undirected graph G on n vertices two continuous optimization problems taken over the n-dimensional cube are presented and it is proved that their optimum values equal the domination number γ of G.

Inequalities involving independence domination, $f$-domination, connected and total $f$-domination numbers [PDF]

open access: yes, 2000
summary:Let $f$ be an integer-valued function defined on the vertex set $V(G)$ of a graph $G$. A subset $D$ of $V(G)$ is an $f$-dominating set if each vertex $x$ outside $D$ is adjacent to at least $f(x)$ vertices in $D$.

SIGNED 2-DOMINATION IN CATERPILLARS [PDF]

open access: yes, 2003
summary:A caterpillar is a tree with the property that after deleting all its vertices of degree 1 a simple path is obtained. The signed 2-domination number $\gamma ^2_{\mathrm s}(G)$ and the signed total 2-domination number $\gamma ^2_{\mathrm {st}}(G)$

Restrained roman domination in graphs [PDF]

open access: yesTransactions 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

The Number of Minimum Dominating Sets in Pn × P2 [PDF]

open access: yes, 2010
A set S of vertices in a graph G is said to be a Smarandachely k-dominating set if each vertex of G is dominated by at least k vertices of S.

In Palantir we trust? Regulation of data analysis platforms in public security

open access: yesBig Data & Society
Organizations increasingly rely on digital technologies to perform tasks. To do so, they have to integrate data banks to make the data usable. We argue that there is a growing, academically underexplored market consisting of data integration and analysis

Survey on Roman {2}-Domination

open access: yesMathematics
The notion of Roman {2}-domination was introduced in 2016 as a variant of Roman domination, a concept inspired by a defending strategy used by the emperor Constantine (272–337 AD) to protect the Roman Empire.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.
