On hop Roman domination in trees

open access: yesCommunications in Combinatorics and Optimization, 2019
Summary: Let \(G=(V,E)\) be a graph. A subset \(S\subset V\) is a hop dominating set if every vertex outside \(S\) is at distance two from a vertex of \(S\). A hop dominating set \(S\) which induces a connected subgraph is called a connected hop dominating set of \(G\).

Complement Activation Linked to Type II Interferon Signaling in Still Disease

open access: yesArthritis &Rheumatology, EarlyView.
Objective Still disease (SD) is an autoinflammatory syndrome characterized by innate immune dysregulation. Although complement can drive inflammation, its involvement in SD remains to be defined. Thus, we aimed to assess complement activation in SD. Methods Complement was assessed using transcriptomic, proteomic, and in vitro approaches. RNA sequencing

Weak Roman domination in graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2011
0(w) = f(w) if w 2 V − fu,vg, has no undefended vertex. The weight of f is w(f) = P v2V f(v). The weak Roman domination number, denoted by r(G), is the minimum weight of a WRDF in G. In this paper, we characterize the class of trees and split graphs for which r(G) = (G) and find r-value for a caterpillar, a 2 n grid graph and a complete binary tree.

The situated professional: Preservice teachers' profiling of globally competent teachers and visions of their ‘possible professional self’

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In response to globalisation, teacher education programmes worldwide are tasked with preparing globally competent teachers (GCTs). Prevailing conceptions of global competence are largely derived from Western‐centric humanistic, neoliberal and transformative narratives, creating a complex landscape for teacher identity formation.

Perfect Roman and Perfect Italian Domination of Cartesian Product Graphs

open access: yesScientific Journal of King Faisal University: Basic and Applied Sciences
For a graph G=(V,E), a function f:V→{0,1,2} is a perfect Roman dominating function (PRDF) on G if every v∈V with f(v)=0 is adjacent to exactly one vertex u with f(u)=2. The sum ∑_(v∈V)^▒f (v) is the weight w(f) of f.

Chilean science teachers' conceptualisations of disability when teaching students with autism

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This study examines how Chilean secondary science teachers conceptualise disability when teaching students with autism in integrated classroom settings. Grounded in critical disability studies, the research employs a qualitative story‐completion method, using a fictional classroom scenario to prompt teachers to construct narratives that reveal

A note on the edge Roman domination in trees

open access: yesElectronic Journal of Graph Theory and Applications, 2017
A subset $X$ of edges of a graph $G$ is called an \textit{edgedominating set} of $G$ if every edge not in $X$ is adjacent tosome edge in $X$. The edge domination number $\gamma'(G)$ of $G$ is the minimum cardinality taken over all edge dominating sets of

Heat stress in spermatogenesis: a redox‐dependent decision network linking ROS, autophagy, and regulated cell death

open access: yesBiological Reviews, EarlyView.
ABSTRACT Heat stress (HS) is an increasing threat to male reproductive health, disrupting spermatogenesis through complex and interdependent cellular responses within the seminiferous epithelium. Although excessive reactive oxygen species (ROS) production is a hallmark of HS, ROS also act as central regulators of cell fate decisions beyond their role ...

Navigating the Double Edge of Product‐Service Systems: User Behavior, Adoption, and Rebound Effects

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Product‐service systems (PSS) have been considered a promising approach to operationalizing the circular economy. Although many studies have outlined the potential sustainability gains of PSS solutions, it is still unclear what factors drive PSS adoption and how behavioral changes result in rebound effects, undermining their potential ...

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
