A new class of block codes with low state complexity of their conventional trellis representations called double zero-tail terminated convolutional codes (DZT codes) is introduced. It is shown that there exist DZT-codes meeting the Varshamov-Gilbert bound on the minimum distance and having asymptotically optimal state complexity. Two ways of constructing DZT-codes are considered. Examples of DZT-c

In a cross-sectional study of diabetic patients diagnosed at or after 30 years, and with different stages of retinopathy, factors such as duration of diabetes, treatment mode, metabolic control, blood pressure, and clinical signs of nephropathy were examined. The different stages of retinopathy used were absence of retinopathy, simplex, and severe retinopathy. Patients with simplex and severe reti

Lyme borreliosis (LB) is the most common vector-borne disease in the northern hemisphere, and southern Sweden is a highly endemic area. In over 70% of the cases, LB is represented by the non-disseminated cutaneous form erythema migrans (EM). This thesis has its focus on EM from a primary health care perspective in southern Sweden, including aspects on epidemiology, the clinical picture, gender dif

Graft copolymers containing poly(ethylene oxide) side chains on a polystyrene backbone have been synthesized. Styrene copolymers synthesized by free radical mechanism and containing between 5 and 15 mol % acrylamide or methacrylamide were used as backbones. The amide groups in the copolymers were ionized by using potassium tert-butoxide or potassium naphthalene, and grafting was achieved by utiliz

A method of analyzing & describing the acoustic properties of fricatives is developed & applied to the fricatives & to the fricative components of the affricates of Standard Chinese. The method consists of making f spectra using the Fast Fourier Transform & analyzing the spectra in terms of critical bands. Three measures are proposed for characterizing the fricative spectra: the ce

Myeloperoxidase ( MPO) is one of the major target antigens of antineutrophil cytoplasmic autoantibodies ( ANCA) found in patients with small-vessel vasculitis and pauci-immune necrotizing glomerulonephritis. To date, the target epitopes of MPO-ANCA remain poorly defined. Human MPO-ANCA do not typically bind mouse MPO. We utilized the differences between human and mouse MPO to identify the target r

A dispersion experiment, where the tracer SF6 Was released from line sources, was carried out within a young pine forest. Line sources made of silicone tubes were installed at different heights and distances from a tower. Vertical concentration profiles were measured on the tower and the samples were analysed with a gas chromatograph. The measured concentration profiles were compared to those calc

This article traces the reception of the the Swedish film Ingeborg Holm in 1913. The film created a fierce debate regarding the Swedish poor laws. This debate eventually led to changes in the law in 1918.

Objective: To relate the pattern of neuropsychological impairments among schizophrenic patients to case history data and disease characteristics in a cross-sectional study of unselected patients, and to integrate these data with two previous longitudinal studies of neuropsychological impairments among schizophrenic patients. Method: One hundred consecutive schizophrenic patients were studied with

BACKGROUND: The role of cell adhesion molecules and transmigration of PMNs through the endothelial barrier is probably essential in intestinal ischemia and reperfusion (I/R)-induced gut barrier dysfunction. Although cytokines are released in I/R, it is unclear whether cytokines directly increase permeability or if this phenomenon requires both expression of cell adhesion molecules and PMN adhesion

Popular Abstract in Swedish Trälimfogar är en väsentlig del av modern träkonstruktionsteknik. För att höja förädlingsvärdet hos träråvaran, tillverkas idag flera olika sorters produkter vilka är beroende av limfogar. Exempel på sådana produkter är limträ och fanerträ (LVL). Ett annat exempel där limfogar används är vid inlimning av skruvar eller stänger för sammanfogning eller förstärkning av limtThis thesis, which is a compilation of seven papers, concerns the mechanical testing, numerical analysis and constitutive modelling of wood-adhesive bonds in timber engineering. Applications such as finger-joints, glued-laminated timber and glued-in rods are considered. The experimental studies include the testing of the fracture characteristics of wood-adhesive bonds, including both wood-to-wood

This paper describes the development and optimization of an amperometric biosensor for monitoring ethanol in beverages. The biosensor is constructed by cross-linking a quinoprotein alcohol dehydrogenase (QH-ADH) to an Os-complex-modified poly(vinylimidazole) redox polymer using poly(ethylene glycol) diglycidyl ether. The optimum biosensor configuration was evaluated by changing the ratio between e

A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm2. A fundamental oscillation frequency of 800 MHz
