A defensive alliance in a graph is a set $S$ of vertices with the property that every vertex in $S$ has at most one moreneighbor outside of $S$ than it has inside of $S$. A defensive alliance $S$ is called global if it forms a dominating set. The global defensive alliance number of a graph $G$ is the minimum cardinality of a global defensive alliance in $G$. In this article we study the global ...

for many years, the prevailing notion of security has been associated with the ‘realist’ militaryside of conflict management, understood as ‘national security’. for us the term does not just mean theinterplay of deterring, compelling, defensive and offensive force in the pursuit of a self-defined nationalinterest. above all, and at a fundamental level it includes the safety and quality of life ...

Several investigations demonstrated that anxiety is the most common mental health disorder worldwide affected about one in 13 people. Anxiety disorders are more commonly reported in Western societies but it is also a main health problem in non-Western countries as stress and anxiety levels have drastically increased over the last two decades. Several wars in Middle Eastern countries in the last...

in his perspective “navigating between stealth advocacy and unconscious dogmatism: the challenge of researching the norms, politics and power of global health,” ooms argues that actions taken in the field of global health are dependent not only on available resources, but on the normative premise that guides how these resources are spent. this comment sets out how the application of a predomina...

‎the global fom and gmres algorithms are among the effective‎ ‎methods to solve sylvester matrix equations‎. ‎in this paper‎, ‎we‎ ‎study these algorithms in the case that the coefficient matrices‎ ‎are real symmetric (real symmetric positive definite) and extract‎ ‎two cg-type algorithms for solving generalized sylvester matrix‎ ‎equations‎. ‎the proposed methods are iterative projection metho...

this study proposes a modified version of cultural algorithms (cas) which benefits from rule-based system for influence function. this rule-based system selects and applies the suitable knowledge source according to the distribution of the solutions. this is important to use appropriate influence function to apply to a specific individual, regarding to its role in the search process. this rule ...

the cuckoo search algorithm is a recently developedmeta-heuristic optimization algorithm, which is suitable forsolving optimization problems. to enhance the accuracy andconvergence rate of this algorithm, an improved cuckoo searchalgorithm is proposed in this paper. normally, the parametersof the cuckoo search are kept constant. this may lead todecreasing the efficiency of the algorithm. to cop...

medical mobilities offer both opportunities and challenges. this tension follows the same ratio as many other historic fora, but offers at the same time a sustainable equilibrium. multi-disciplines are, therefore, the key to the medical lifeworld for the global health and well-being of transnational health users around the globe.
