On global offensive alliance in zero-divisor graphs [PDF]
arXiv, 2021 Let $\G(V,E)$ be a simple graph without loops nor multiple edges. A nonempty subset $S \subseteq V$ is said a {\em global offensive alliance} if every vertex $v \in V- S$ satisfies that $\d_S(v) \geq \d_{\overline{S}}(v)+1$. The {\em global offensive alliance number} $\g^o(\Gamma)$ is defined as the minimum cardinality among all global offensive ...

Reentrant phase transitions and defensive alliances in social dilemmas with informed strategies [PDF]
EPL 110 (2015) 38003, 2015 Knowing the strategy of an opponent in a competitive environment conveys obvious evolutionary advantages. But this information is costly, and the benefit of being informed may not necessarily offset the additional cost. Here we introduce social dilemmas with informed strategies, and we show that this gives rise to two cyclically dominant triplets that ...

Arthritis Care &Research, EarlyView.Objective This study aimed to identify themes contributing to resilience in childhood‐onset systemic lupus erythematosus (cSLE), distinguish between profiles of resilience, and examine how they relate to underlying themes and patient characteristics. Methods We conducted a mixed‐methods study of 21 patients with cSLE aged 11 to 19 years at a Canadian ...

Offensive Alliances in Graphs [PDF]
arXiv, 2022 A set $S\subseteq V$ of vertices is an offensive alliance in an undirected graph $G=(V,E)$ if each $v\in N(S)$ has at least as many neighbours in $S$ as it has neighbours (including itself) not in $S$. We study the classical and parameterized complexity of the Offensive Alliance problem, where the aim is to find a minimum size offensive alliance.

Arthritis Care &Research, EarlyView.Objective Autoimmune rheumatic diseases commonly affect individuals of childbearing age, with historically increased adverse pregnancy outcomes in this group. The advent of disease‐modifying antirheumatic drugs (DMARDs) has fostered more suitable conditions for pregnancy; however, this is accompanied by challenges in ensuring safe use in reproductive ...

Alliances and Conflict, or Conflict and Alliances? Appraising the Causal Effect of Alliances on Conflict [PDF]
arXiv, 2019 The deterrent effect of military alliances is well documented and widely accepted. However, such work has typically assumed that alliances are exogenous. This is problematic as alliances may simultaneously influence the probability of conflict and be influenced by the probability of conflict.

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide
Advanced Functional Materials, EarlyView.An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Spectral study of alliances in graphs [PDF]
Discussiones Mathematicae Graph Theory 27 (1) (2007) 143-157, 2006 In this paper we obtain several tight bounds on different types of alliance numbers of a graph: (global) defensive alliance number, global offensive alliance number and global dual alliance number. In particular, we investigate the relationship between the alliance numbers of a graph and its algebraic connectivity, its spectral radius, and its ...
