Energy Cooperatives (ECoops), the most prominent example for Communities, are attributed great importance energy transition both through engagement of end-consumers and increase local renewable sources. We conducted an exploratory (spatial) data analysis to study which indicators European Social Progress Index Quality Life co-occure with presence ECoops. Results show that these indexes their su...

Let I be an instance of binary boolean CSP. Consider the problem of deciding whether one can remove at most k constraints of I such that the remaining constraints are satisfiable. We call it the Almost CSP problem. This problem is NP-complete and we study it from the point of view of parameterized complexity where k is the parameter. Two special cases have been studied: when the constraints are...

Diquark-antidiquark states are expected to exist as a natural complement of mesons and baryons. Although they were predicted long ago, and some candidates were found experimentally, none has, as yet, been reliably identied. We suggest that the search for the so-called C(1480)-meson in reactions such as photoproduction N ! N and KN ! should provide a decisive way to settle this issue. Estimates ...

We point out that in a large class of superstring–inspired E(6) models, either an e+e− collider operating at a center–of–mass energy √ s = 1.5 TeV or higher must detect the pair production of charged or neutral exotic leptons, or an e+e− collider with √ s ≥ 300 GeV must discover at least one light neutral Higgs boson with invisible branching ratio exceeding 50%. If neither of these two signals ...

We point out that in a large class of superstring{inspired E(6) models, either an e + e ? collider operating at a center{of{mass energy p s = 1:5 TeV or higher must detect the pair production of charged or neutral exotic leptons, or an e + e ? collider with p s 300 GeV must discover at least one light neutral Higgs boson with invisible branching ratio exceeding 50%. If neither of these two sign...

In recent years we are witnessing enormous development of e-government, which has brought about great changes in our society. This study examines the relationship between the levels of egovernment and the quality of government information access, pointing out that e-government principles are based on the assumption that government information should be accessed among all kinds of organizations....
