A model-independent search for deviations from the Standard Model prediction is performed in e(+) p and e(-) p collisions at HERA using H1 data corresponding to an integrated luminosity of 117 pb(-1). For the first time all event topologies involving isolated electrons, photons, muons, neutrinos and jets with high transverse momenta are investigated in a single analysis. Events are assigned to exc

Popular AbstractStudier om undomars arbetsmotivation och inställning till arbete fokuserar ofta på skolundomar, vilket kan ge idealiserade bilder eftersom dessa ungdomar ännu inte försökt ta sig in på arbetsmarknaden. Verica Stojanovics avhandling fokuserar emellertid på ”äldre” (20-29 åriga) svenska och danska ungdomar som varit arbetslösa i några månader eller mer och hunnit känna av hur det är My aim is to show how unemployed youth, in Sweden and Denmark, during the years 1992-1996, were coping with their situation as unemployed, by focusing on their motivation for work, their conception of work, and their alternative action. Swedish youth have for a number of decades lived with a labour market policy which has had full employment as a goal and included active measures. Danish youth hav

The error-correcting capability of tailbiting codes generated by convolutional encoders is described. In order to obtain a description beyond what the minimum distance d min of the tailbiting code implies, the active tailbiting segment distance is introduced. The description of correctable error patterns via active distances leads to an upper bound on the decoding block error probability of tailbi

The hypothesis that spatial-memory specialization affects the size of the hippocampus has become widely accepted among scientists. The hypothesis comes from studies on birds primarily in two families, the Paridae (tits, titmice and chickadees) and the Corvidae (crows, nutcrackers, jays, etc.). Many species in these families store food and rely on spatial memory to relocate the cached items. The hi

An integrated technique for test scheduling and scan-chain division under power constraints is proposed in this paper. We demonstrate that optimal test time can be achieved for systems tested by an arbitrary number of tests per core using scan-chain division and we define an algorithm for it. The design of wrappers to allow different lengths of scan-chains per core is also outlined. We investigate

Human skin fibroblasts in different growth states were incubated with [3H]glucosamine and/or Na(2)35SO4 and extracted with Triton X-100 for various periods of time. Free heparan-sulphate oligosaccharides and protein-bound heparan-sulphate chains were separated by chromatography on octyl-Sepharose and analyzed. A pool of endogenously produced oligosaccharides, present in the cultured cells and isol

PURPOSE: To report an interim analysis of the registry data and evaluate the performance of Trufill DCS Orbit coils in terms of the stability of initial aneurysmal occlusion. MATERIALS AND METHODS: From May 1, 2004, to February 1, 2006, 291 patients with ruptured or unruptured aneurysms were enrolled in a multiple-center global registry from 37 centers in the United States, Europe, and Latin Ameri

Energy consumption is today an important design issue for all kinds of digital systems, and essential for the battery operated ones. An important fraction of this energy is dissipated on the processors running the application software. To reduce this energy consumption, one may, for instance, lower the processor clock frequency and supply voltage. This, however, might lead to a performance degrada

We review applications of high-order harmonic generation in different fields of physics, from spectroscopic studies of atoms and molecules, to interferometry and plasma diagnostics and nonlinear optics.

The blood group ABO genotypes of 138 group O individuals with three different ethnic origins in Brazil were determined, including Whites, Blacks and Amerindians. Several previously undescribed O alleles were found, predominantly in the Black group, in which about a third of the samples did not conform to previously known O allele structures. It has been well documented for the first time that some

I will discuss some aspects of modeling diffractive final states with event generators. In the first part of the talk I will discuss multiple scatterings in hard diffraction in hadron collisions and its effects on gap survival and hadronization corrections. In the second part I will argue that the study of the 'pomeron remnant' in hard diffraction at HERA may be the best way of distinguishing reso
