Sugars dominate the seagrass rhizosphere
Nature Ecology & Evolution, 2022 Seagrasses are among the most efficient sinks of carbon dioxide on Earth. While carbon sequestration in terrestrial plants is linked to the microorganisms living in their soils, the interactions of seagrasses with their rhizospheres are poorly understood.

α-cyanobacteria possessing form IA RuBisCO globally dominate aquatic habitats
The ISME Journal, 2022 RuBisCO (ribulose 1,5-bisphosphate carboxylase/oxygenase) is one the most abundant enzymes on Earth. Virtually all food webs depend on its activity to supply fixed carbon.

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).

Iron colloids dominate sedimentary supply to the ocean interior
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Phytoplankton assimilate carbon dioxide, produce oxygen, and nourish food webs on a scale that impacts planetary processes but are limited by iron deficiency over much of the global surface ocean. Therefore, we must understand processes that

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 $2\alpha(G) \cdot \log{n}$.

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.

Domination in functigraphs [PDF]
Discussiones Mathematicae Graph Theory, 2012 Let $G_1$ and $G_2$ be disjoint copies of a graph $G$, and let $f: V(G_1) \rightarrow V(G_2)$ be a function. Then a \emph{functigraph} $C(G, f)=(V, E)$ has the vertex set $V=V(G_1) \cup V(G_2)$ and the edge set $E=E(G_1) \cup E(G_2) \cup \{uv \mid u \in V(G_1), v \in V(G_2), v=f(u)\}$.

Secretory Cells Dominate Airway CFTR Expression and Function in Human Airway Superficial Epithelia.
American Journal of Respiratory and Critical Care Medicine, 2020 RATIONALE Identification of the specific cell types expressing CFTR is required for precision medicine therapies for cystic fibrosis (CF). However, a full characterization of CFTR expression in normal human airway epithelia is missing.

Relating domination, exponential domination, and porous exponential domination
Discrete Optimization, 2017 The domination number $γ(G)$ of a graph $G$, its exponential domination number $γ_e(G)$, and its porous exponential domination number $γ_e^*(G)$ satisfy $γ_e^*(G)\leq γ_e(G)\leq γ(G)$. We contribute results about the gaps in these inequalities as well as the graphs for which some of the inequalities hold with equality.
