Domination parameters with number 2: interrelations and algorithmic consequences
, 2016 In this paper, we study the most basic domination invariants in graphs, in which number 2 is intrinsic part of their definitions. We classify them upon three criteria, two of which give the following previously studied invariants: the weak $2$-domination

The tradition of an ancient Greek colony in Malta [PDF]
, 1983 The persistent tradition of a Greek colonization of the Maltese Islands in ancient times was inspired mainly by ancient literary allusions. These are basically 1) the identification of the Homeric island of Ogygia, Calypso's refuge, with Malta; 2) the ...

How 1st‐Tier Suppliers Respond to Green Public Procurement Policies: An Empirical Analysis
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This article analyses how 1st‐tier suppliers to public organisations respond operationally to Green Public Procurement (GPP) policies. Through a multiple case study of 12 Italian firms operating in different sectors, we develop a classification of suppliers' responses, identifying two interrelated macro‐types: internal operations realignment ...

A Note on Roman Domination of Digraphs
Discussiones Mathematicae Graph Theory, 2019 A vertex subset S of a digraph D is called a dominating set of D if every vertex not in S is adjacent from at least one vertex in S. The domination number of a digraph D, denoted by γ(D), is the minimum cardinality of a dominating set of D.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Iterative solvers are advantageous for handling nonlinear structural analysis problems. The iterative solvers often require updating the stiffness matrix, which limits their application in static and pseudo‐dynamic hybrid simulations because: (1) updating the stiffness matrix of a system involving a physical specimen is challenging; (2 ...

Signed Total Roman Domination in Digraphs
Discussiones Mathematicae Graph Theory, 2017 Let D be a finite and simple digraph with vertex set V (D). A signed total Roman dominating function (STRDF) on a digraph D is a function f : V (D) → {−1, 1, 2} satisfying the conditions that (i) ∑x∈N−(v)f(x) ≥ 1 for each v ∈ V (D), where N−(v) consists ...

Food Safety and Health, EarlyView.Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Bounds on the restrained Roman domination number of a graph
Communications in Combinatorics and Optimization, 2016 A {\em Roman dominating function} on a graph $G$ is a function $f:V(G)\rightarrow \{0,1,2\}$ satisfying the condition that every vertex $u$ for which $f(u) = 0$ is adjacent to at least one vertex $v$ for which $f(v) =2$.
