This licentiate thesis is in the field of biomedical signal processing with main focus on processing of cardiac signals measured on the body surface or invasively from patients with atrial fibrillation (AF). The first part addresses spatial analysis of AF using VCG data synthesized from the 12-lead ECG. Two parameters each are extracted to characterize the spatial orientation as well as the spatia

A family of active distance measures for general convolutional codes is defined. These distances are generalizations of the extended distances introduced by Thommesen and Justesen (1983) for unit memory convolutional codes. It is shown that the error correcting capability of a convolutional code is determined by the active distances. The ensemble of periodically time-varying convolutional codes is

In the course of human immunodeficiency virus (HIV) disease, CCR5-utilizing HIV type 1 (HIV-1) variants (R5), which typically transmit infection and dominate its early stages, persist in approximately half of the infected individuals (nonswitch virus patients), while in the other half (switch virus patients), viruses using CXCR4 (X4 or R5X4) emerge, leading to rapid disease progression. Here, we u

En vanligt förekommande utmaning i högre utbildning är översiktskurser med snäva tidsramar och heterogena studentgrupper. Artikeln vill peka på den positiva potentialen i sådana omständigheter genom att presentera ett konkret exempel på ett arbetssätt som har visat sig framgångsrikt inom skådespelarutbildningens musikundervisning: tonsättningsuppgifter som konceptualiseras individuellt och realise

Abstracts Purpose: The purpose of this work was to contribute to a better understanding of challenges and solutions to equitable provision of assistive technologies in resource limited environments by (i) describing sources of awareness, types of providers and costs of assistive technologies; (ii) describing common reasons for not possessing assistive technologies; and (iii) comparing these source

Artikeln behandlar den antinazistiska tidningen "Trots allt" under andra världskriget och upphovsmannen Ture Nerman. Den politiska situationen och dess betydelse för tidningen diskuteras.

Objective: The incidence of type 1 diabetes shows a large variation worldwide, but whether the causes are environmental or genetic has not been settled. We examine here the incidence of type 1 diabetes among second-generation immigrants and adoptees from abroad to disentangle genetic/ethnic vs. environmental influence, assuming adoptees from abroad have similar environmental exposures compared wit

A statistical model based on four kallikrein markers (total prostate-specific antigen [tPSA], free PSA [fPSA], intact PSA, and human kallikrein-related peptidase 2) in blood can predict risk of Gleason score ≥7 (high-grade) cancer at prostate biopsy.

A discussion on whether and why archaeology is important, with Mårup Church (Denmark) as point of departure. The church will soon fall into the sea. Why is it crucial to save or document this church? Rhetorical catchwords, cultural mangagement, archaeology, history and social anthropology are presented and critically examined.

Abstract in SpanishResumen: Interpretar a Peirce no constituyo más que el primer momento de una investigación seria de la iconicidad. También hay que tener en cuenta las aportaciones de la fenomenología de Husserl, de la psicología de percepción y de las ciencias cognoscitivas. Sobre todo, las antinomias interiores a la teoría semiótica y los argumentos críticos formulados entorno a la iconicidad

Objective. To study the kinetics of lipid micro-emboli during cardiac surgery. Design. Eleven pigs were studied. Seven of these were put on extracorporeal circulation. A shed blood phantom consisted of blood, saline and radioactive triolein was added to the circuit. Both venous and arterial blood samples were taken at short intervals. Four animals were used to study renal kinetics without extracor
