Using two-pulse photon echo excitation a strong resonance in the measured homogeneous dephasing time as a function of magnetic field is observed in the H-3(4)-D-1(2) transition of Pr3+:YAlO3. The resonance could only be observed at low excitation energies since it otherwise was masked by excitation intensity dependent extra dephasing processes in the crystal. Thus intensity dependent dephasing pro

The use of test-coverage measures (e.g., block-coverage to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test-coverage helps achieve higher defect-coverage and therefore improves software quality. In practice, data often show that defect-coverage and test-coverage grow over time, as additional testing is performed. How

The paper gives an overview of the planned orbit correc- tion system for the 3 GeV storage ring at the MAX IV lab- oratory, a light source facility currently under construction in Lund, Sweden[1, 2]. The ring will have a vertical beam size in the 1-4μm range in the insertion device (ID) straight sections depending on coupling[3], which places high re- quirements on the orbit stability. To meet thi

The gene for the human glandular kallikrein, prostate-specific antigen, has been cloned. The sequence of 7130 nucleotides encompassing the gene and 633 bp of 5' and 639 bp of 3' flanking DNA has been determined. The translation initiation site was slightly heterogeneous, yielding 5' non-translated leader sequences of 41 and 35 bp. The gene is divided into five exons, with introns located at positi

A decomposition of the field of the wave equation in three dimensions is suggested. This wave splitting decomposes the field into two components such that in free space simple propagation properties are obtained. The inhomogeneous region is assumed to have a phase velocity variation that varies only in the radial coordinate r from the origin. The suggested wave splitting is a generalization of the

A direct search for lepton-flavour-violating H -> mu tau decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the H -> mu tau(had) channel, where tau(had) is a hadronically decaying tau-lepton. The search is based on the data sample of proton-proton collisions collected by the ATLAS experiment corresponding to an integrated lum

BACKGROUND: Preterm birth remains the major risk factor for the development of intraventricular hemorrhage, an injury that occurs in 25% of very low birth weight infants. Intraventricular hemorrhage is thought to be venous in origin and intrinsic thromboses in the germinal matrix are likely to play a triggering role. Antithrombin, a glycoprotein synthesized in the liver, is the major plasma inhibi

This volume provides an overview of applications of conceptual spaces theory, beginning with an introduction to the modeling tool that unifies the chapters. The first section explores issues of linguistic semantics, including speakers negotiation of meaning. Further sections address computational and ontological aspects of constructing conceptual spaces, while the final section looks at philosophi

Residential fires are often unequally distributed over residentialareas. In a Swedish research project - Residential fires in the metropolitanareas - underlying factors behind residential fires are analyzed in thecities of Malmö, Gothenburg and Stockholm. A central researchquestion is how geographical differences between residential fires andunderlying socio-economic factors in the cities can be a

The laminar burning velocity is a fundamental property of combustiblemixtures important for kinetic model validation as well as for practicalapplications. Many efforts are directed towards its accurate determination.The heat flux method is one of the commonly recognized methodsfor measuring laminar burning velocity, however, the information on theaccuracy of the method is scattered in the literatu
