The Davies transformation is a method to transform the steering vector of a uniform circular array (UCA) to one with Vandermonde form. As such, it allows techniques such as spatial smoothing for direction-of-arrival (DOA) estimation in a correlated signal environment, developed originally for uniform linear arrays, to be applied to UCAs. However, the Davies transformation can be highly sensitive t

High-spin states in the mass A~60 region were populated using the state-of-art gamma-ray spectrometers Gammasphere, Euroball, and GASP in conjunction with dedicated ancillary detectors. In particular, the 59Cu nucleus was studied in several experiments, and a very extensive level scheme was determined. It comprises more than 320 transitions connecting about 150 excited states. Relative to mass, it

A novel approach of applying priorities to memory allocation is presented and it is shown how this can be used to enhance the robustness of real-time applications. The proposed mechanisms can also be used to increase performance of systems with automatic memory management by limiting the amount of garbage collection work. A way of introducing priorities for memory allocation in a Java system witho

This study was undertaken to find out if about 25% right cardiac output is sufficient for preservation of lung function during prolonged periods of venoarterial extracorporeal membrane oxygenation. Six healthy pigs weighing 57 kg were subjected to 18-hour venoarterial extracorporeal membrane oxygenation. During this period 1200 ml/min venous blood was delivered to the lungs through the pulmonary a

OBJECTIVE - To estimate the prevalence of and the cardiovascular risk associated with the metabolic syndrome using the new definition proposed by the World Health Organisation (WHO). RESEARCH DESIGN AND METHODS - A total of 4,483 subjects aged 35-70 years participating in a large family study of type 2 diabetes in Finland and Sweden (the Botnia study) were included in the analysis of cardiovascula

Objective: To evaluate meat intake patterns in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts. Design and setting: 24-Hour dietary recalls were assessed within the framework of a prospective cohort study in 27 centres across 10 European countries by means of standardised computer-assisted interviews. Subjects: In total, 22 924 women and 13 031 men aged 35-74 years.

Popular Abstract in Swedish Denna avhandling handlar om hur man kan mäta små mängder av ett antal intressanta molekyler i en vattenlösning med hjälp av infrarödspektroskopi. Det är viktigt att kunna bestämma mängden av olika spårämnen i en vattenlösning i en rad olika tillämpningar. Några viktiga exempel på sådana tillämpningar är inom sjukvården för diagnostiska ändamål, bland annat för blodprovsThis thesis treats various aspects of the measurement of trace components in aqueous solutions with Fourier transform infrared spectroscopy. This technique has several applications from such diverse fields as dairy industry and biomedical optics. The use of infrared spectroscopy for trace component quantification is made difficult by the large absorption of water which dominates the spectrum. The

BACKGROUND AND PURPOSE: The aim of the study was to determine the prevalences of carotid artery disease and major and minor potential cardioembolic sources (1) in patients with cerebral infarction and age-matched control subjects and (2) in different clinical subtypes of cerebral infarction. METHODS: A series of 166 consecutive patients with cerebral infarction and 59 control subjects was examined

The electronic properties of quantum dot (QD) arrays are strongly influenced by the Coulomb interaction of electrons within the dot as well as with those in neighbouring dots. In this paper, we investigate this behaviour taking into account screening by a free electron gas in the vicinity of the QDs. We find pronounced effects for standard capacitance - voltage ( CV) measurements of QD structures

The changes in plasma gastrin-releasing peptide (GRP), arginine vasopressin (AVP), neuropeptide Y (NPY), corticotropin releasing hormone (CRH), galanin, ACTH, cortisol, delta sleep-inducing peptide (DSIP), adrenaline, noradrenaline and pancreatic polypeptide (PP) were measured after 5 and 15 minutes of acute insulin-induced moderate hypoglycaemia (2.0 mmol/l) in 10 patients with Type 1 diabetes me

We have performed an eight-band k center dot p model calculation on the current-voltage (I-V) curves associated with interband magnetotransport in a double-barrier broken-gap heterostructure using the Burt-Foreman multiband envelope function theory and the scattering matrix approach. In a sample with very thin barriers, the broadening Gamma(0) of a virtual bound state with energy E-0 can be very l

The intra-molecular, proton-coupled electron transfer from a tyrosine residue to covalently linked tris-bipyridine ruthenium(III) complexes in aqueous solution (Ru-III-TyrOH --> Ru-II-TyrO(.) + H+) is studied in two complexes. The Ru-III-TyrOH state is generated by laser flash-induced photo-oxidation in the presence of the electron acceptor methyl viologen. The reaction is shown to follow either a

Glioblastoma multiforme (GBM) and other high-grade brain tumours are typically characterized by complex chromosome abnormalities and extensive intratumour cytogenetic heterogeneity. The mechanisms behind this diversity have been little explored. In this study, we analysed the pattern of chromosome segregation at mitosis in 20 brain tumours. We found an abnormal segregation of chromatids at mitosis
