DOMINATION AND EDGE DOMINATION IN TREES [PDF]

Ural Mathematical Journal, 2020
Let \(G=(V,E)\) be a simple graph. A set \(S\subseteq V\) is a dominating set if every vertex in \(V \setminus S\) is adjacent to a vertex in \(S\). The domination number of a graph \(G\), denoted by \(\gamma(G)\) is the minimum cardinality of a dominating set of \(G\). A set \(D \subseteq E\) is an edge dominating set if every edge in \(E\setminus D\)

Evaluation of the cardioprotective effect of l-carnitine and silymarin in cancer patients receiving anthracycline-containing chemotherapy [PDF]

Journal of Bioscience and Applied Research, 2020
Aim: Anthracycline-induced cardiotoxicity is the most common constraint of its use in the treatment of various types of cancer. This study aimed to investigate the benefits of the addition of the l-carnitine / silymarin to anthracycline chemotherapy in ...

Domination versus edge domination [PDF]

Discrete Applied Mathematics, 2020
We propose the conjecture that the domination number $γ(G)$ of a $Δ$-regular graph $G$ with $Δ\geq 1$ is always at most its edge domination number $γ_e(G)$, which coincides with the domination number of its line graph. We prove that $γ(G)\leq \left(1+\frac{2(Δ-1)}{Δ2^Δ}\right)γ_e(G)$ for general $Δ\geq 1$, and $γ(G)\leq \left(\frac{7}{6}-\frac{1}{204 ...

Sesquiterpenes dominate monoterpenes in northern wetland emissions [PDF]

Atmospheric Chemistry and Physics, 2020
We have studied biogenic volatile organic compound (BVOC) emissions and their ambient concentrations at a sub-Arctic wetland (Lompolojänkkä, Finland), which is an open, nutrient-rich sedge fen and a part of the Pallas-Sodankylä Global Atmosphere Watch ...

A big encapsulated adrenal mass with well-circumscribed margin

Urology Case Reports, 2021
We present a case on adrenal schwannomas. The CT shows enhancement of distal adrenal gland lesion. We named it rabbit tail sign. Adrenal schwannomas are rare and presents a very small proportion of retroperitoneal schwannomas. It tends to be misdiagnosed

Dominating Sets and Domination Polynomials of Paths [PDF]

International Journal of Mathematics and Mathematical Sciences, 2009
Let G = (V, E) be a simple graph. A set S⊆V is a dominating set of G, if every vertex in V\S is adjacent to at least one vertex in S. Let be the family of all dominating sets of a path Pn with cardinality i, and let . In this paper, we construct , and obtain a recursive formula for d(Pn, i).

Exotic herbivores dominate Australian high‐elevation grasslands

Conservation Science and Practice, 2022
Invasive species are major drivers of ecosystem degradation globally. How invasive herbivore impacts differ from native herbivore impacts remains understudied.

Efficacy of l-carnitine and silymarin administration on the health-related quality of life in 120 patients with cancer undergoing anthracycline-based chemotherapy [PDF]

Journal of Medical and Life Science, 2020
Objectives: To investigate changes after adding L-carnitine and silymarin compared to anthracycline chemotherapy alone on the health-related quality of life (HRQoL) of women with breast cancer receiving anthracycline-based chemotherapy.

Domination and Fractional Domination in Digraphs

The Electronic Journal of Combinatorics, 2018
In this paper, we investigate the relation between the (fractional) domination number of a digraph $G$ and the independence number of its underlying graph, denoted by $\alpha(G)$. More precisely, we prove that every digraph $G$ on $n$ vertices has fractional domination number at most $2\alpha(G)$ and domination number at most $2\alpha(G) \cdot \log{n}$.

Domination Reliability [PDF]

The Electronic Journal of Combinatorics, 2012
In this paper, we propose a new network reliability measure for some particular kind of service networks, which we refer to as domination reliability. We relate this new reliability measure to the domination polynomial of a graph and the coverage probability of a hypergraph.
