We present rational rate k/n punctured convolutional codes (n up to 8, k=1, ···, n-1, and constraint length ν up to 8) with good performance. Many of these codes improve the free distance and (or) weight spectra over previously reported codes with the same parameters. The tabulated codes are found by an exhaustive (or a random) search
Objectives: On account of the increasing worldwide problems associated with overweight and obesity, the aim of the present study was to examine BMI change over 5 years in relation to different lifestyle-, demographic- and psychosocial work-related factors. METHODS: A cohort of 9913 persons responded to an identical survey in 2000 and 2005. BMI change over the period was examined in relation to gen
Popular Abstract in Swedish Med utvecklingen av lasern tillkom ett diagnostiserningsverktyg för forskning inom medicin, biologi, fysik, kemi mm. En laser är i princip en ljuskälla som skickar ut ljus med synnerligen välbestämd färg och riktning. Ljus som har en viss färg kan påverka vissa molekyler och atomer. Under vissa förutsättningar svarar dessa ämnen genom att i sin tur skicka ut ljus i en aLaser based diagnostic tools have had an exploding impact on fundamental as well as applied research in a number of disciplines, such as biomedicine, physical chemistry etc over the last decades. Whereas fundamental research often investigate phenomena in extreme conditions, applied research aims at performing in-situ measurements, in order to understand the many aspects and entangled phenomena th
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
