Gravity’s Rainbow: Modeling the World Trade Network

Abstract. The gravity model, long the empirical workhorse for modeling international trade, has recently been put on firmer theoretical foundations (Anderson and van Wincoop, 2003; Helpman, Melitz and Rubinstein, 2008). These theoretical models emphasize how economic conditions in the rest of the world affect bilateral trade. Nevertheless, standard applications of the gravity model ignore the n...

Molecular Dynamics Simulation of the Melting Process in Au15Ag40 Nanoalloys

In this study the operations of melting of Au15Ag40 nanoalloy have been studied using the molecular dynamic simulations through the Gupta multiparticle potential and the nonergodicity of simulations is eliminated by the multiple histogram method. The melting characteristics are determined by the analysis of variations in the potential energy. The calculations indicate that the melting of Au15Ag...

Rainbow Matchings and Rainbow Connectedness

Aharoni and Berger conjectured that every collection of n matchings of size n+1 in a bipartite graph contains a rainbow matching of size n. This conjecture is related to several old conjectures of Ryser, Brualdi, and Stein about transversals in Latin squares. There have been many recent partial results about the Aharoni-Berger Conjecture. The conjecture is known to hold when the matchings are m...

Development of International Trade in Health Services in the Legal System of World Trade Organization

The World Trade Organization, as one of the youngest international organizations following its 50th activity of predecessor means the General Agreement on Tariffs and Trade in the Multilateral Trade System, through the establishment of a General Agreement on Trade in Services, regulated the domain of International Trade in services and by designating Integrated legal framework for the advanceme...
