Shor’s quantum factoring algorithm and the efficient simulation of quantum evolutions by quantum computers are compelling evidence that quantum physics will change the landscape of information science in the future. Despite great progress in the last two decades, the construction of a large scale quantum computer is still in its infancy, largely due to decoherence. A revolutionary idea that eme...

Wadge reducibility in the Baire and Cantor spaces is very important in descriptive set theory. We consider Wadge reducibility in so called φ-spaces which are topological counterpart of the algebraic directed-complete partial orderings. It turns out that in many spaces the Wadge reducibility behaves worse than in the classical case but there exist also interesting examples of spaces with a bette...

As been recently pointed out, physically relevant models derived from string theory require the presence of non-vanishing form fluxes besides the usual geometrical constraints. In the case of NS-NS fluxes, the Generalized Complex Geometry encodes these informations in a beautiful geometrical structure. On the other hand, the R-R fluxes call for supergeometry as the underlying mathematical frame...

The concept of the good death has been widely considered. However, perspectives those affected have not received sufficient attention. In our empirical study, we conducted interviews with 32 people who were confronted dying; these either terminally ill, elderly or else bereaved carers. findings show that for this group people, dying is just a physical process, but also psychological, social and...
