Continues positive airway pressure (CPAP) is recommended for treatment of sleep apnoea (SA) in patients with congestive heart failure (CHF) but is not easily tolerated resulting in poor patient compliance. Mandibular advancement device (MAD) is designed to inhibit pharyngeal airway (PAW) obstruction and may be a valuable alternative. It has been proposed that MAD exerts its effect by increasing PA

The hindered diffusion and binding of proteins of different sizes (lysozyme, BSA and IgG) in an agarose gel is described using adsorption kinetic and diffusional data together with an experimentally determined pore size distribution in the gel. The validity of the pore model, including variable diffusion coefficients and porosities is tested against experimental confocal microscopy data. No fittin

A computer program for evaluating colour factors of QCD Feynman diagrams is presented, and illustrative examples on how to use the program to calculate nontrivial colour factors are given. The program and the discussion in this paper is based on a diagrammatic approach to colour factors.

BEAST is a Bidirectional Efficient Algorithm for Searching code Trees. In this paper, it is used for decoding block codes over the additive white Gaussian noise (AWGN) channel. If no constraints are imposed on the decoding complexity (in terms of the number of visited nodes during the search), BEAST performs maximum-likelihood (ML) decoding. At the cost of a negligible performance degradation, BEA

The high-resolution far-infrared spectrum of the intermolecular HC1 libration band v(4)(1) of the OC-H(35)C1 heterodimer is recorded in the gas phase by means of Fourier transform IR spectroscopy in a static multipass absorption cell at 137 K using a synchrotron radiation source. This is the first direct observation of an intermolecular vibration band of the OC-HC1 dimer in the gas phase. The rota

We studied the A-band photodissociation of bromoiodomethane, CH2BrI, in acetonitrile solution at room temperature by femtosecond pump-probe spectroscopy, Initiated by the 266 nm light, this reaction leads to the CH2Br-I isomer, most likely produced via in-cage recombination of the CH,Br and I photofragments. The isomer is formed vibrationally excited with a time constant of similar to7.5 ps and th

Primary headaches (e.g. migraine and cluster headache), the symptoms of which is associated with cranial vascular activity, is likely to be dependent on a primary central nervous system dysfunction. To further our understanding of the mechanisms behind primary headaches, we investigated the central projections of sensory nerves from three cranial vessels by tract-tracing techniques. In papers I-I

Background: Airway inflammation is associated with an increased expression and release of inflammatory reactants that regulate processes of cell migration, activation and degranulation. The purpose of this study was to quantify bronchial lavage (BAL) fluid and serum levels of chemokine (IL-8), secretory leukocyte protease inhibitor (SLPI), soluble intracellular adhesion molecules-1 (sICAM-1) and s

A supramolecular complex composed of Ru(II) tris-bipyridine, tyrosine, and dipicolylamine was synthesized and characterized. This complex was attached to TiO2 nanocrystalline films via ester groups at the Ru(II) chromophore, and photoinduced multistep electron transfer was investigated by laser flash photolysis and electron paramagnetic resonance techniques. Following ultrafast electron injection

In 1999, seven dark-bellied brent geese Branta bemicla bemicla were followed during spring migration from western Europe to Arctic Russia using satellite telemetry. For six of the birds we were also able to monitor their summer stay at the Taymyr Peninsula, and for five birds part of their autumn migration was recorded. In this article, we report on site use during summer and spring/autumn migrati

De senaste åren har bjudit på en veritabel revolution beträffande tekniken i fordon. Utvecklingen av kraftfulla, billiga och pålitliga mikroprocessorer har öppnat dörren för avancerad datorbaserad styrning av en mångfald fordonsfunktioner. Mycket av den nya tekniken syns inte på utsidan av fordonen, men innebär väsentliga förbättringar för miljö, säkerhet, ekonomi och bekvämlighet.

Texas has rapidly emerged as one of the leading wind power markets in the United States. This development can be largely traced to a well-designed and carefully implemented renewables portfolio standard (RPS). The RPS is a new policy mechanism that has received increasing attention as an attractive approach to support renewable power generation. Though replacing existing renewable energy policies

We introduce a novel soft antenna selection approach for multiple antenna systems through a joint design of both RF (radio frequency) and baseband signal processing. When only a limited number of frequency converters are available, conventional antenna selection schemes show severe performance degradation in most fading channels. To alleviate those degradations, we propose to adopt a transformatio
