Studies investigating risk factors associated with atrial fibrillation (AF) have mostly focused on AF presence and burden, disregarding the temporal distribution of AF episodes although such information can be relevant. In the present study, the alternating, bivariate Hawkes model was used to characterize paroxysmal AF episode patterns. Two parameters: the intensity ratio µ, describing the dominat
The frequency of fibrillatory waves (f-waves), Ff, exhibits significant variation over time, and previous studies suggest that some of this variation is related to respiratory modulation through the autonomic nervous system. In this study, we tested the hypothesis that this variation (?Ff) could be related to acetylcholine concentration ([ACh]) release pattern. Electrocardiograms were recorded fro
The present study addresses the problem of respiratory rate estimation from ECG-derived respiration (EDR) signals during paroxysmal atrial fibrillation (AF). Novel signal-to-noise ratios between various components of the ECG including the influence of respiration, measured by QRS ensemble variance, the amplitude of fibrillatory waves (f-waves), and the QRS amplitude are introduced to characterize
En översiktlig presentation av av tre äldre skräckserietidningar för en yngre kvinnlig publik: brittiska Spellbound (1976-1978), brittiska Misty (1978-1980) och tyska Vanessa (1982-1990).
Facing increasing pressure to decarbonize, innovation within the shipping sector has turned to low-and zero carbon solutions. In this paper we investigate how the development and implementation of biodiesel and liquefied biogas (LBG) in Norwegian coastal shipping has been influenced by the technological alignment with fossil fuels. We understand this influence to emanate from the (mis)match of bioFacing increasing pressure to decarbonize, innovation within the shipping sector has turned to low-and zero carbon solutions. In this paper we investigate how the development and implementation of biodiesel and liquefied biogas (LBG) in Norwegian coastal shipping has been influenced by the technological alignment with fossil fuels.

Pulmonary vein isolation (PVI) is considered a standard treatment of paroxysmal atrial fibrillation aiming to restore and maintain sinus rhythm. The purpose of this study is to analyse how the PVI treatment affects the electrical conduction pattern in the atria. We have compared the morphology of P wave loops extracted from the vectorcardiogram (VCG) before and after PVI. Ten patients suffering fr
Background: It is unclear if a non-radical diagnostic biopsy entails a higher risk for metastasis and poorer survival for patients with cutaneous head and neck melanoma (cHNM). Aims/objectives: To assess whether or not initial diagnostic biopsy modality and radicality (clear, positive, or narrow histopathological margins) influence recurrence and survival in patients with cHNM. Materials and metho
Over the last decade, representations of the rainbow were repeatedly disputed in Poland, revealing the country’s ongoing socio-political changes and its drift away from the generally liberal and secular values of the European mainstream. These cases show a political growth and an increasing social diffusion of Polish ‘national paleoconservatism.’ The aim of this article is to (1) discuss the intel
The optical and electrochemical properties of a series of polyoxometalate (POM) oxoclusters decorated with two bodipy (boron-dipyrromethene) light-harvesting units were examined. Evaluated here in this polyanionic donor-acceptor system is the effect of the solvent and associated counterions on the intramolecular photoinduced electron transfer. The results show that both solvents and counterions ha
In this paper, an aerosol-based process is proven for imparting antibacterial property to textiles. Nanoparticles of copper and silver are produced by means of glow discharge between two electrodes in nitrogen at atmospheric pressure and passed through fabrics of cotton and polyester which act as filter media. The bactericidal performance of the nanofinished fabrics is assessed against Gram-positi
In this paper we propose a design methodology to partition dataflow applications on a multi clock domain architecture. This work shows how starting from a high level dataflow representation of a dynamic program it is possible to reduce the overall power consumption without impacting the performances. Two different approaches are illustrated, both based on the post-processing and analysis of the ca
Decision-making is central to Software Product Management (SPM) and includes deciding on requirements priorities and the content of coming releases. Several algorithms for prioritization and release planning have been proposed, where humans with or without machine support enact a series of steps to produce a decision outcome. Instead of applying some specific algorithm to find an acceptable soluti
Parser generators are an indispensable tool for rapid language devel- opment. However, they often fall short of the finesse of a hand-crafted parser, built with the language semantics in mind. One area where generated parsers have pro- vided unsatisfactory results is that of error recovery. Good error recovery is both natural, giving recovery suggestions in line with the intention of the programme
Background: Emergency Department crowding is associated with increased morbidity and mortality but no measure of crowding has been validated in Sweden. We have previously derived and internally validated the Skåne Emergency Department Assessment of Patient Load (SEAL) score as a measure of crowding in Emergency Departments (ED) in a large regional healthcare system in Sweden. Due to differences in
An increased incidence of narcolepsy type 1 (NT1) was observed in Scandinavia following the 2009–2010 influenza Pandemrix vaccination. The association between NT1 and HLA-DQB1*06:02:01 supported the view of the vaccine as an etiological agent. A/H1N1 hemagglutinin (HA) is the main antigenic determinant of the host neutralization antibody response. Using two different immunoassays, the Luciferase I
