POLDIS is a Monte Carlo program for polarized (semi-inclusive) deep inelastic scattering (DIS). Unpolarized DIS events are generated with the existing lepto-production event generators LEPTO for DIS and AROMA for Heavy Flavor production. The relevant spin asymmetries are computed at partonic level to first order in αs for each generated event, and are then convoluted with the corresponding rati...

Multiple input/multiple output (MIMO) is a hot topic in wireless communication and has great advantage in capacity. We investigate the influence of antenna topology on MIMO capacity and by comparing three topology schemes we find that selecting a proper antenna topology increases the capacity evidently. Three schemes under study are the traditional point-to-point concentrated antenna topology (...

In deeply inelastic lepton-nucleus scattering (DIS), the average jet transverse momentum is broadened because of the multiple scattering in the nuclear medium. The size of jet broadening is proportional to the multi-parton correlation functions inside nuclei. We show that at leading order, jet broadening in DIS and nulcear enhancement in di-jet momentum imbalance and DrellYan 〈q2 T 〉 share the ...

The executed study evaluated the influence of manual and speech input on driving quality, stress and strain situation and user acceptance when using a Driver Information System (DIS). The study is part of the EU-project SENECA. 16 subjects took part in the investigations. A car was equipped with a modified DIS to carry out the evaluation in real traffic situations. The used DIS is a standard pr...

The vast majority of lichenicolous fungi are relatively host-specific, nonvirulent ascomycetes and heterobasidiomycetes. A few known lichenicolous homobasidiomycetes (mushroom-forming fungi) generally exhibit broad host ecologies and in some cases, high virulence. Many produce conspicuous sclerotia or bulbils, thought to be adaptive in dispersal and survival. To more clearly understand the evol...

a case with two simultaneous dens invaginations (dis) and one dens evagination (de) in a permanent maxillary lateral incisor is reported for the first time in a 21-year-old girl. de known as talon cusp of the anterior teeth is a rare entity and its co-existence with di has been reported scarcely in the literature. simultaneous occurrence of two dis with one de has not been reported elsewhere. u...

Data integration consists in providing a uniform access to a set of heterogeneous sources through a common representation called global schema. In this paper we present DIS@DIS, a data integration system that adopts innovative techniques for query answering in a complex integration environment. In particular, DIS@DIS is able to deal with integrity constraints, which are used to enhance the expr...
