Analysis of atrial rhythm is important in the treatment and management of patients with atrial fibrillation. Several algorithms exist for extracting the atrial signal from the electrocardiogram (ECG) in atrial fibrillation, but there are few reports on how well these techniques are able to recover the atrial signal. We assessed and compared three algorithms for extracting the atria] signal from th

The class I genes of the major histocompatibility complex (Mhc) are here investigated for the first time in a passerine bird. The great reed warbler is a rare species in Sweden with a few semi-isolated populations. Yet, we found extensive Mhc class I variation in the study population. The variable exon 3, corresponding to the alpha(2) domain, was amplified from genomic DNA with degenerated primers

Med utgångspunkt i ett fall, en ryttare som drunknade då han försökte ta sig över Helgeån, diskuteras hur drunkningar utreddes i början av 1700-talet

Background and Purpose - Depression after stroke is often described as underdiagnosed and undertreated. However, there are few data on self-reported depression and use of antidepressants in stroke patients at large. Materials and Methods - In the Swedish national quality assessment register, Riks-Stroke, 15 747 stroke survivors are recorded. They were asked about depressive mood and antidepressant

The effect of different molecular weight polystyrenes (PS) on the phase behavior of sodium 1,4-bis(2-ethylhexyl) sulfosuccinate (AOT)/water/cyclohexane oil-continuous microemulsions was investigated. The surfactant-covered water droplets were treated as a pseudocomponent in the mixture, and ternary polymer/droplet/oil phase diagrams were established as a function of microemulsion droplet radius (2

The prognostic value of histopathological response to preoperative radiotherapy (50 Gy) in radically resected oral carcinomas was studied in 39 consecutive patients. Microvessel density (MVD) was evaluated for relation to radioresponse and outcome. Resected tumour tissue was examined histopathologically and response to radiotherapy was scored according to induced morphological changes. Pretreatmen

I denna rapport beskrivs några av de mekanismer som kan leda till sprickbildning. Rapporten behandlar enbart de fuktrelaterade mekanismerna. Samma mekanismer kan även relateras till temperaturrörelser. Det som förorsakar sprickor är förhindrade rörelser hos putsen.

Sediment-dispersed extraterrestrial chromite grains (63-355 mu m) have been recovered in a section across the Arenig-Llanvirn transition in the Killerod quarry in southeastern Scania. Previous studies of the same stratigraphic interval in the Orthoceratite Limestone at Kinnekulle, ca. 350 km to the north in Vastergotland, have shown a two orders of magnitude increase in extraterrestrial chromite b

Popular Abstract in Swedish Idag lagras allt fler kartor digitalt och nya metoder krävs för att förbättra denna digitala hantering. Ett område som studerats under senare tid är automatiska metoder för kartografisk generalisering. Kartografisk generalisering innebär att man förenklar informationen i en karta för att göra den mer lättläst i den önskade skalan. Denna avhandling beskriver en optimerinCartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. Two topics are treated: optimisation methods in graphic generalisation, and propagation of updates between cartographi

The DTMROC-S is a 16-channeI front-end chip developed for the signal processing of the ATLAS straw tube detector, TRT. Due to a highly radioactive environment, the chip is fabricated in a commercial 0.25μm CMOS technology hardened by layout techniques and, in addition, a special methodology was used to improve the circuit's robustness against Single Events Effects (SEE) caused by ionizing particle

Pharmacy-grade exogenous lung surfactant preparations of bovine and porcine origin, dispersed in physiological electrolyte solution have been studied. The organization and dynamics at the air/water interface at physiological temperature was analysed by neutron reflection. The results show that a well-defined surface phase is formed, consisting of a multilayer structure of lipid/protein bilayers al

Shore and shoreline evolution both due to natural and human-induced causes or factors can be variable over a wide range of different temporal and/or spatial scales. Our capability to understand and especially predict this variability is still limited. This can lead to misinterpretation of coastal change information, which hampers informed decision making and the subsequent design and implementatio

The relationship among CCR5 genotype, cytomegalovirus infection, and disease progression and death was studied among 159 human immunodeficiency virus (HIV)-infected patients with hemophilia. One patient (0.6%) had the CCR5Delta32/CCR5Delta32 genotype (which occurs in similar to2% of the Scandinavian population) and a rapid disease course. His HIV V3 region contained genotypic features attributable

We performed ultrasound measurements (QUS) of the calcaneus in a population-based setting on 280 healthy children, aged 11-16 years, from a small urban area in southern Sweden. The results are compared with dual-energy X-ray absorptiometry (DXA) measurements in the total body, the lumbar spine and the hip, as well as single-energy X-ray absorptiometry (SXA) of the forearm. Normative data and corre

We consider algorithms for simulation of iterated Itô integrals with application to simulation of stochastic differential equations. The fact that the iterated Itô integral I_{ij}(t_n,t_n+h)=\int_{t_n}^{t_n+h} \int_{t_n}^{s} dW_{i}(u)dW_{j}(s) conditioned on W_i(t_n+h)-W_i(t_n) and W_j(t_n+h)-W_j(t_n), has an infinitely divisible distribution is utilised for the simultaneous simulation of $I_{ij}(
