A new approach of analyzing GRB light curves

We estimated the Txx quantiles of the cumulative GRB light curves using our recalculated background. The basic information of the light curves was extracted by multivariate statistical methods. The possible classes of the light curves are also briefly discussed.Comment: 4 pages, 8 figure

The Transformation of Hungarian Production Cooperatives and Future Consequences

This research examines the transformation of Hungarian agricultural production cooperatives. In contrast to early expectations, cooperatives did not experience much membership loss. Rather, the enterprises held together, although they downsized. The distribution of collective assets occurred quickly and created much tension. The sector experienced a severe decapitalization, and the efficiency of the sector fell. There was a sharp rise in unemployment. Sales and marketing were disrupted. Thus, the cooperatives transformed in a very hostile situation. They survived, and some prospered, yet, in general, they remain vulnerable to adverse economic developments. Healthy cooperatives will be vital to the success of smaller private farms.Agribusiness,

On Renyi entropies characterizing the shape and the extension of the phase space representation of quantum wave functions in disordered systems

We discuss some properties of the generalized entropies, called Renyi entropies and their application to the case of continuous distributions. In particular it is shown that these measures of complexity can be divergent, however, their differences are free from these divergences thus enabling them to be good candidates for the description of the extension and the shape of continuous distributions. We apply this formalism to the projection of wave functions onto the coherent state basis, i.e. to the Husimi representation. We also show how the localization properties of the Husimi distribution on average can be reconstructed from its marginal distributions that are calculated in position and momentum space in the case when the phase space has no structure, i.e. no classical limit can be defined. Numerical simulations on a one dimensional disordered system corroborate our expectations.Comment: 8 pages with 2 embedded eps figures, RevTex4, AmsMath included, submitted to PR
