The purpose of this study was to develop techniques to quantify the propagation pattern of the electrical activation during atrial fibrillation (AF) along a one-dimensional catheter. Taking intra-atrial signal organization aspects into account, the atrial activations are detected and combined into wavefronts. Parameters describing wavefront consistency and activation order along the catheter are d

In this study we investigated the potential neuroprotective effect of 2-oxoglutarate (2-OG) on the hippocampus in the transient vessel occlusion ischemia model in the Mongolian gerbil. The morphological and biochemical studies were performed at 7 days after occlusion of carotid arteries. The acute reduction of NeuN-positive neurons in the CA1 pyramidal layer of the hippocampus was accompanied by i

Several studies have shown excess risk for a number of comorbidities in patients with psoriasis compared with the general population, but data on cause-specific mortality in this patient population are limited. The aim of this study was to estimate the associations of psoriasis and 12 specific causes of death and all-cause mortality in patients with mild and severe psoriasis. The study was based o

A measurement is presented of the cross section for the production of a W boson with one or two jets, of which at least one must be a b-jet, in pp collisions at root s = 7 TeV. Production via top decay is not included in the signal definition. The measurement is based on 35 pb(-1) of data collected with the ATLAS detector at the LHC. The W + b-jet cross section is defined for jets reconstructed wi

The crystal structures of the binary cadmium-rich complex metal alloys NiCd6+delta (-0.32 <= delta <= 0.35) and NiCd1+delta (0 <= d <= 0.05) were studied by means of single crystal X-ray diffraction. The partitioning of the NiCd6+delta structure into clusters grouped around all 16 high symmetry points of the face centered cubic cell leads to the identification of two partial structures forming rep

To identify susceptibility loci for classical Hodgkin's lymphoma (cHL), we conducted a genome-wide association study of 589 individuals with cHL (cases) and 5,199 controls with validation in four independent samples totaling 2,057 cases and 3,416 controls. We identified three new susceptibility loci at 2p16.1 (rs1432295, REL, odds ratio (OR) = 1.22, combined P = 1.91 x 10(-8)), 8q24.21 (rs2019960,

In this thesis, the Wideband Sparse Exponential Mode Analysis (WSEMA) estimator is introduced. It combines two recently developed techniques, the wideband dictionary and the Sparse Exponential Mode Analysis (SEMA) to make for an efficient estimator. WSEMA estimates the parameters of decaying sinusoids, without a priori-information about the number of modes present in the signal. WSEMA works with a

Unmanned vehicles need robust systems to ensure the safety of the vehicle and its environment. Being able to find and avoid perilous situations is paramount to such a system. In this paper we suggest an unsupervised image-based anomaly detection algorithm using a variational autoencoder and a superpixel segmentation algorithm, which is adapted to the maritime obstacle detection task. The algorithm

Bombus terrestris is one of the most commonly used insect models to investigate visually guided behavior and spatial vision in particular. Two fundamental measures of spatial vision are spatial resolution and contrast sensitivity. In this study, we report the threshold of spatial resolution in B. terrestris and characterize the contrast sensitivity function of the bumblebee visual system for a dua

Uppsatsen handlar om ogiltigförklaring och skadestånd inom ramen för ämnet tvister om uppsägnings- och avskeds giltighet. Uppsatsen använder en kombination av rättsdogmatisk och rättsanalytisk metod. Syftet med uppsatsen är att klargöra, problematisera och jämföra gällande rätt med LAS-utredningens- och överenskommelsens förslag inom ramen för uppsatsens ämne. Syftet är vidare att analysera potent

A well-ordered surface oxide grown on Fe(110) has been studied using scanning tunneling microscopy (STM), low energy electron diffraction, low energy electron microscopy, and core level photoelectron spectroscopy. The iron oxide film exhibits wide terraces and is formed after exposure to 100-1000 L at 1 x 10(-6) mbar O-2 and 400 degrees C. Two domains, mirror symmetric in the Fe(110)-lattice mirro

In the present work, the formation of complex coacervate micelles and aggregates of the oppositely charged diblock copolymers poly(N-isopropylacrylamide)27-b-poly((3-acrylamidopropyl)trimethylammoniumchloride)15 [PNIPAAM27-b-PAMPTMA15(+)] and poly(N-isopropylacrylamide)27-b-poly(2-acrylamido-2-methyl-1-propanesulfonic sodium)15 [PNIPAAM27-b-PAMPS15(-)] in aqueous solution have been studied at diff

Droughts affect ecosystems at multiple time scales, but their sub-seasonal legacy effects on vegetation activity remain unclear. Combining the satellite-based enhanced vegetation index MODIS EVI with a novel location-specific definition of the growing season, we quantify drought impacts on sub-seasonal vegetation activity and the subsequent recovery in the Northern Hemisphere. Drought legacy effec
