After a brief historical comment on the study of BRS(or BRST) symmetry , we discuss the quantization of gauge theories with Gribov copies. A path integral with BRST symmetry can be formulated by summing the Gribov-type copies in a very specific way if the functional correspondence between τ and the gauge parameter ω defined by τ(x) = f(Aμ(x)) is “globally single valued”, where f(A ω μ(x)) = 0 s...

We read with interest the ‘Journal Club’ section in the September 2016 issue of Indian Pediatrics, which commented on a randomized controlled trial on association between the Safe Delivery App and quality of care and perinatal survival in Ethiopia [1]. The commentary from an evidence-based-medicine viewpoint [2] rightly suggests that there are limited randomized controlled trials and systematic...

This paper reviews the theory, phenomenology, and observational constraints on the coupling parameters of Einstein-aether gravity, i.e. General Relativity coupled to a dynamical unit timelike vector field. Several new remarks and a discussion of open issues are included.

since the verbs of and have similar use and play an important role in arabic grammar, it was useful to study both and discuss about their functions. following the discussion we found that there is five different functions for :first, it is an imperfect verb, (that give the noun an nominative case and the comment an objective case) arabic grammar experts disagree if it has a verb function or a n...

The invisible hands of peer reviewers play a determining role in the eventual fate of submissions to international English-medium journals. This study builds on the assumption that non-native researchers and prospective academic authors may find the whole strive for publication, and more specifically, the tough review process, less threatening if they are aware of journal reviewers’ expectation...

The axioms for "independent choices" presented in van Lambalgen [1992] are strengthened here, so that they can be seen as introducing a new type of indiscernibles in set theory. The resulting system allows for the construction of natural inner models. The article is organised as follows. Section 1 introduces the axioms, some preliminary lemmas are proved and the relation with the axiom of choic...
