[k]-Roman Domination in Digraphs
, 2023 Let D=(V(D),A(D)) be a finite, simple digraph and k a positive integer. A function f:V(D)→{0,1,2,…,k+1} is called a [k]-Roman dominating function (for short, [k]-RDF) if f(AN−[v])≥|AN−(v)|+k for any vertex v∈V(D), where AN&

Mathematics Interdisciplinary ResearchLet G=(V(G),E(G)) be a graph and h be a function defined from V(G) to {0,1,2,3}. A vertex x with h(x)=0 is said to be undefended with respect to $h$ if it has no neighbor assigned 2 or 3 under h.

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

Biological 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
Business 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 ...

Double domination in lexicographic product graphs [PDF]
, 2020 [EN] In a graph G, a vertex dominates itself and its neighbours. A subset S subset of V(G) is said to be a double dominating set of G if S dominates every vertex of G at least twice.
