The spectrum of the QCD Dirac operator and chiral random matrix theory: the threefold way. Abstract We argue that the spectrum of the QCD Dirac operator near zero virtuality can be described by random matrix theory. As in the case of classical random matrix ensembles of Dyson we have three different cases: the chiral orthogonal ensemble (chGOE), the chiral unitary ensemble (chGUE) and the chira...

On modeling door-to-door parcel delivery services in Iran

Parcel delivery is a complex logistic service, as it serves many small or medium-sized customers who may send or receive parcels. Modeling such delivery system needs to integrate two different research areas of hub location and vehicle routing. As it totally depends on the network and the linkage of the nodes, in this paper, some door-to-door service providers are taken into account to provide ...

We review the main reasons pushing us beyond the SM and we argue in favor of new physics at the electroweak scale (hence experimentally accessible at present or near–future machines). We focus on the appealing possibility that such new physics is given by a super-symmetric (SUSY) extension of the SM. We discuss the minimal case, Constrained Minimal Supersymmetric SM, and more general (maybe mor...

Conventional pharmacologic treatments for major depressive disorder (MDD) generally take several weeks to several months to have a clinically meaningful effect. This time lag to response constitutes a major burden for patients and contributes to increased morbidity and mortality. Two published studies in patients with MDD have now provided evidence for rapid and robust antidepressant efficacy o...
