In this paper we report whether conserved currents can be sensibly defined in supersym-metric minisuperspaces. Our analysis deals with a k = +1 FRW model. Supermatter in the form of scalar supermultiplets is included. We show that conserved currents cannot be adequately established except for some very simple scenarios. More details can be found in ref. 3,5. N=1 supergravity 1 constitutes a " s...

The usual formulation of quantum theory is rather abstract (it employs complex Hilbert spaces, Hermitian operators, the trace rule, and unitary or superoperator evolution). It is natural to ask why the formalism is like this. In this paper we will show that, for finite dimensional systems, this rather abstract formalism follows from a set of reasonable axioms. These axioms might well have been ...

Applications of atmospheric science are relevant to a range of themes within science and society; application to entomology is the main focus of this meeting. The talks are designed to appeal to the broader scientific community by showcasing areas of science that encompass both disciplines. The audience will hear about exciting topics within weather and climate change, how they are applied to e...

We read with great interest the article (November, 2000) by Drs Vural and Tas,demir [1]. We have several concerns regarding the paper. As the authors emphasized, posterior left ventriculectomy or Batista procedure is an important surgical option for severe or end-stage heart failure. We think the amount and extension of resected viable muscle segment is a very crucial point for this special pro...
