For the C*-crossed product C*(Sigma) associated with an arbitrary topological dynamical system Sigma = (X, sigma), we provide a detailed analysis of the commutant, in C*(Sigma), of C(X) and the commutant of the image of C(X) under an arbitrary Hilbert space representation (pi) over tilde of C*(E), In particular, we give a concrete description of these commutants, and also determine their spectra.
Monte Carlo simulation is frequently employed to compute p-values for test statistics with unknown null distributions. However, the computations can be exceedingly time-consuming, and, in such cases, the use of pre-computed simulations can be considered to increase speed. This approach is attractive in principle, but complicated in practice because the size of the pre-computed data can be prohibit
Objective. The first successful pregnancy after heart transplantation was reported in 1988. Worldwide experience with heart and heart/lung transplanted (H-HLTx) pregnant women is limited. To expand this knowledge the collaborating Nordic thoracic transplant centers wanted to collect information on all such pregnancies from their centers. Design. Information was retrospectively collected on all H-H
Magnetic materials with high magnetic coercivity (Hc), magnetic anisotropy (Ku) and low Gilbert damping (α) are of great importance for future spintronics devices. For instance, for spin-transfer-torque (STT) memory devices low α and high Ku are desired. Such a combination of material properties includes a built in contradiction since both Ku and α are dependent on the spin-orbit interaction (SO);
Ischemic heart disease is the leading cause of death in high-income parts of the world and is caused mainly by atherosclerosis in the coronary arteries. The rupture of an atherosclerotic plaque with subsequent platelet activation and clot formation can lead to myocardial infarction (MI). Atherosclerosis is a complex process, which involves the accumulation and oxidation of low-density lipoprotein
Three species of Caloplaca are described as new to science: Caloplaca caesiosorediata Arup & van den Boom, a corticolous species and two saxicolous species, Caloplaca catillarioides Arup & van den Boom, and C. caesioisidiata Arup & van den Boom, all from the archipelago of Cape Verde. They are dark-fruited and have a pale to dark greyish crustose thallus. None of the new species are ph
BACKGROUND: Agriculture consistently ranks as one of the highest risk industries in North America and Europe. In addition to vehicle injuries and other injuries that occur on farms, farm vehicle drivers are also involved in collisions involving tractors and other slow-moving vehicles (SMVs) on public roads. These collisions often lead to injuries among farmers, family members, farm workers, and ot
The MAX IV Laboratory in Lund is currently operating two storage rings, the 1.5 GeV MAX II and the 700MeV MAX III, as well as constructing the new facility MAX IV, which will house a 1.5 GeV and a 3 GeV ring. At the MAX II synchrotron there are three hard X-ray beamlines at which crystallography can be performed: I711, I811 and I911. Beamline I711 is mainly used for powder diffraction. I811 is an
Hypoxia is a well-described phenomenon in the offshore waters of the Baltic Sea with both the spatial extent and intensity of hypoxia known to have increased due to anthropogenic eutrophication, however, an unknown amount of hypoxia is present in the coastal zone. Here we report on the widespread unprecedented occurrence of hypoxia across the coastal zone of the Baltic Sea. We have identified 115
Popular Abstract in Swedish Denna avhandling undersöker de svenska hushållens förväntningar, approximerade av de enkätfrågor som ligger till grund för Konjunkturbarometern. Data har tillhandahållits av Konjunkturinstitutet, och täcker åren 1995-2011. Det första kapitlet utgör en introduktion till ämnet. I kapitlet relateras en del av den mycket stora forskningslitteraturen till avhandlingens övergThis thesis investigates survey expectations from the Economic Tendency Survey for households, provided by the Swedish National Institute of Economic Research, for the years 1995-2011. The first chapter relates a part of the research literature to the overall purpose of the thesis, which is to investigate rational properties of empirical expectations. The second chapter presents the results of con
In 2011 a field survey of the bryophyte vegetation and flora of Stora Alvaret, the largest continuous alvar area in Sweden situated on the Baltic island of Öland (SE Sweden), was initiated. A number of transects crossing the alvar area from west to east will be surveyed. The aim of the investigation is to try and elucidate the realtionship between the bryophyte flora and environmental parameters s
The aim of this article is to reflect on the evolution of total quality management (TQM) as the most widespread quality management approach during the last 25 years. However, during the first 10 years of the new millennium, the term TQM seems to have lost its attractiveness in Western parts of the world and instead new terms such as Business Excellence, Organisational Excellence, Six Sigma, and Le
The purpose of this study is to compare the value of statistical life (VSL) estimates for traffic, drowning, and fire accidents. Using a choice experiment in a mail survey of 5,000 Swedish respondents we estimated the willingness to pay for risk reductions in the three accidents. In the experiment respondents were asked a series of questions, whether they would choose risk reducing investments whe
The long-term sustainability of a software product depends on more than developing features. Priorities are placed on aspects that support the development of software, like software product quality (eg. ISO 9126), project constraints — time and cost, and even the development of intellectual capital (IC). A greater focus on any one aspect takes priority from another, but as each aspects delivers a
