Recently two new classes of low-rate codes have been presented. The first class is the super-orthogonal turbo codes (SOTCs) and the second is the maximum free distance (MFD) convolutional codes. In this paper we present an evaluation of the performance vs. arithmetic decoding complexity for these codes and compare them with the previously reported super-orthogonal convolutional codes (SOCCs). For
This thesis concerns the prediction of the fluid mechanical conditions in some specific large vessels in the human body. Large vessels are special in the way that the Reynolds number is relatively high and in the case of arteries the flow is pulsatile. The aim is to contribute to the knowledge of flow patterns in large vessels, and ways to predict and measure fluid mechanical parameters such as sh

Popular Abstract in Swedish Hemolytiskt uremiskt syndrom (HUS) och trombotiskt trombocytopen purpura (TTP) är allvarliga sjukdomar hos barn och vuxna. HUS kännetecknas av mikroangiopatisk hemolytisk anemi (blodbrist med nedbrytning av röda blodkroppar), trombocytopeni (låga blodplättar) och akut njursvikt. Det är den vanligaste orsaken till akut njursvikt hos barn. Typisk HUS utlöses av tarminfektThis study investigated the pathogenesis of hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). (1) The relative roles of lipopolysaccharide and Shiga-like toxin-2 were studied in a mouse model of Escherichia coli O157:H7 infection. Both factors were found to be important for the virulence of the strain and contributed in an additive manner. The mouse model mimicked cert
Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. Most of the energy potential of the degraded material is conserved in the methane, thus providing a renewable energy carrier, which c
The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. Limitation of carbon dioxide and other emissions through emission regulations, carbon taxes, an
This study investigates the topic of forgiveness of sins in the mission of the historical Jesus. Gospel material that pertains to the question is authenticated by the use of criteria for historicity and interpreted within the wider context of first-century Judaism as part of a broader reconstruction of Jesus’ career as a healer and prophet. Questions posed and answered concern the historical plaus
ABSTRACT: BACKGROUND: The two-step dilute acid hydrolysis (DAH) of softwood is costly in energy demands and capital costs. However, it has the advantage that hydrolysis and subsequent removal of hemicellulose-derived sugars can be carried out under conditions of low severity, resulting in a reduction in the level of sugar degradation products during the more severe subsequent steps of cellulose hy
The relationship between a reported history of trauma and dissociative symptoms has been explained in 2 conflicting ways. Pathological dissociation has been conceptualized as a response to antecedent traumatic stress and/or severe psychological adversity. Others have proposed that dissociation makes individuals prone to fantasy, thereby engendering confabulated memories of trauma. We examine data
Differently homogenised and heat treated potato pulp, used as a dietary fibre additive in low-fat sausages, gave rise to an enhanced instrumentally and sensory measured firmness and compactness, respectively. This is believed to be due to the high content of insoluble fibre, which creates a fibrous network that enhances the texture of the sausage, while not interfering with the meat protein networ
Motion estimation in a series of consecutive images is used in a variety of areas, e.g. video compression and investigation of tissue characteristics and organ function in medical images. Several methods exist both for estimating motions on a pixel level, e.g. block-matching in which two blocks in consecutive images are compared by an evaluation metric, and on a sub-pixel level. In this paper, we
Popular Abstract in Swedish Tumörer i ben och mjukdelar är vanliga men utgör endast 1 % av alla maligna neoplasier. De elakartade tumörerna är ofta utmanande att diagnostisera pga deras relativt likartade morfologi samt att de är ovanliga. Således är all tilläggsinformation värdefull och genetiska analysmetoder kan bidra med information som är användbar och i vissa fall tom avgörande för diagnostiTumors of bone and soft tissue are common but only constitute 1 % of all malignant tumors. The malignant tumors are often difficult to diagnose due to their rarity and morphological resemblance between subtypes. This makes the diagnostic process challenging. Thus, there is a need for ancillary techniques, such as genetic analyses, not only for diagnostic purposes, but also for obtaining informatio
The effect of modulating the structure of thin pentacene (C22H14) films by a nanopatterned inert substrate, known as hexagonal boron nitride nanomesh, is reported. Films of different thickness are grown and characterized by x-ray absorption, core-level photoemission, low-energy electron microscopy, microbeam low-energy electron diffraction, and scanning tunneling microscopy. Initially the pentacen
The polarizability and other properties have been studied for F(-), Cl(-), Br(-), and HCOO(-) in water using a combined quantum chemical statistical mechanics simulation model that explicitly takes into account the Pauli repulsion as well as the electrostatic coupling between the QM system and the classical surroundings. It is shown that the surrounding molecules significantly reduce both the pola
Polyphenolic substances, such as flavonoids, attract considerable interest due to their ability to act as antioxidants. The vast majority of studies published deal with the nutritional, biochemical, or chemical structure aspects of these substances while few reports exist on the physico-chemical properties as well as solution behavior of the substances. In this article we report on the precipitati
