Some progress on the mixed roman domination in graphs

, 2021
Let G = (V, E) be a simple graph with vertex setxs V and edge set E. A mixed Roman dominating function of G is a function f : V ∪ E → {0, 1, 2} satisfying the condition that every element x ∈ V ∪ E for which f(x) = 0 is adjacent or incident to at least ...

Connected Roman Hop Dominating Functions in Graphs

European Journal of Pure and Applied Mathematics
Let $G$ be a connected graph. A hop Roman dominating function $f:V(G)\to \{0,1,2\}$ is a connected hop Roman dominating function (CHRDF) on $G$ if the set $\{u\in V(G): f(u)\neq 0\}$ induces a connected subgraph of $G$. The of weight of a CHRDF f is given by $\omega_G^{cRh}(f)=\sum_{v\in V(G)}f(v)$ and the minimum weight among all connected hop Roman ...

Prevalence of Cam Femoroacetabular Lesions in Medieval (1200‐1600 CE) and Postmedieval (1600‐1850 CE) Dutch Skeletal Collections

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate medieval and postmedieval Dutch skeletal collections for signs of cam impingent. Methods The medieval collections from Alkmaar Paardenmarkt and Klaaskinderkerke and the postmedieval period from Middenbeemster were studied. Standard osteological methods for sex and age estimation were used. From digital photographs of the femora, the

Lower bounds on the Roman and independent Roman domination numbers

, 2016
A Roman dominating function (RDF) on a graph G is a function f : V (G) → (0, 1,2) satisfying the condition that every vertex u with f(u) = 0 is adjacent to at least one vertex v of G for which f(v) = 2.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

Biological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Utterance evolution: the road to generative, combinatorial communicators

Biological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

Independent double Roman domination in graphs

AKCE International Journal of Graphs and Combinatorics, 2020
For a graph G = (V,E), a double Roman dominating function has the property that for every vertex with f(v) = 0, either there exists a vertex , with f(u) = 3, or at least two neighbors having f(x) = f(y) = 2, and every vertex with value 1 under f has at ...

Corruption Control and Corporate Hazardous Waste Emissions: Cross‐Country Evidence and the Moderating Role of Agenda 2030

Business Strategy and the Environment, EarlyView.
ABSTRACT The aim of this study is to examine the impact of corruption control, as a public institutional mechanism, on hazardous waste emissions of private sector entities. We also examine the extent to which Agenda 2030 moderates the relationship. We analyse data from the top 500 global companies.

Roman {2}-Domination

, 2016
In this paper, we initiate the study of a variant of Roman dominating functions. For a graph G=(V,E), a Roman {2}-dominating function f:V→{0,1,2} has the property that for every vertex v∈V with f(v)=0, either v is adjacent to a vertex assigned 2 under f,
