The present study introduces sparse modeling for the estimation of propagation patterns in intracardiac atrial fibrillation (AF) signals. The estimation is based on the partial directed coherence (PDC) function, derived from fitting a multivariate autoregressive model to the observed signals. A sparse optimization method is proposed for estimation of the model parameters, namely, the adaptive grou
Background: Computed tomography angiography (CTA) of intracranial arteries has high demands on image quality. Important parameters influencing vessel enhancement are injection rate, concentration of contrast media and tube voltage. Purpose: To evaluate the impact of an increase of contrast media concentration from 300 to 400 mg iodine/mL (mgI/mL) and the effect of a decrease of tube voltage from
Four recombinant Saccharomyces cerevisiae strains with enhanced xylose growth (TMB3400, C1, C5 and BH42) were compared with two control strains (TMB3399, TMB3001) through genome-wide transcription analysis in order to identify novel targets for inverse metabolic engineering. A subset of 13 genes with changed expression levels in all improved strains was selected for further analysis. Thirteen vali
Recent literature on L2 vocabulary testing points to a move away from discrete vocabulary testing towards more embedded and integrative approaches. This paper investigates if the way vocabulary is currently tested at English departments at Swedish universities follows this trend. The survey shows that a great majority of universities use discrete and selective vocabulary tests and that the multipl
Utbildning har förmodligen aldrig haft en mer upphöjd ställning än under de senaste decennierna. Samtidigt befinner sig skolan, eller snarare skolinstitutionen, i kris. Krisen har medfört att lärarna mer definieras som en del av problemet än av lösningen. Försöken att styra läraren i riktning mot en ”maktens lärare”, en anställd som lojalt gör det uppdragsgivaren vill, har därför också stått högt

Determining vaccine dose-level protection is essential to minimize program costs and increase mass vaccination program feasibility. Currently, a 3-dose vaccination schedule is recommended for both the quadrivalent and bivalent human papillomavirus (HPV) vaccines. Although the primary goal of HPV vaccination programs is to prevent cervical cancer, condyloma related to HPV types 6 and 11 is also pre

Abstract in German Sogenannte sexuelle Minderheiten haben in Kanada grundlegende Veränderungen ihres rechtlichen und gesellschaftlichen Status erarbeitet. Zumindest bis in die 1960er Jahre galten schwule Männer auf Grund ihrer ‘Tendenzen’ als Gefahr für die nationale Sicherheit und als leichte Beute für (kommunistische) Erpressung. Gegenwärtig ermöglicht die kanadische Gesetzgebung die Ehe für gle
Background and purpose: Leucocyte infiltration is a rate-limiting step in the pathophysiology of acute pancreatitis (AP) although the adhesive mechanisms supporting leucocyte-endothelium interactions in the pancreas remain elusive. The aim of this study was to define the role of lymphocyte function antigen-1 (LFA-1) in regulating neutrophil-endothelium interactions and tissue damage in severe AP.
Whereas most research in SLA assumes the relationship between the first language (L1) and the second language (L2) to be unidirectional, this study investigates the possibility of a bidirectional relationship. We examine the domain of manner of motion, in which monolingual Japanese and English speakers differ both in speech and gesture. Parallel influences of the L1 on the L2 and the L2 on the L1
Vad händer när en spricka i putsen utsätts för hydrostatiskt vattentryck? Kan vatten transporteras i isoleringen? Hur påverkar horisontella och vertikala isolerskarvar vattenledningen? Kan vatten transporteras i gränsskiktet mellan puts och isolering? Vad händer om vatten når isolerhållarna? Kan vatten nå bakomliggande stomme? I ett forskningsprojekt vid Lunds tekniska högskola har experimentella
