A priori modeling for gradient based inverse scattering algorithms

This paper presents a Fisher information based Bayesian approach to analysis and design of the regularization and preconditioning parameters used with gradient based inverse scattering algorithms. In particular, a one-dimensional inverse problem is considered where the permittivity and conductivity profiles are unknown and the input data consist of the scattered field over a certain bandwidth. A p

Techniques to reduce radiation for patients and operators during aortic endografting.

Endovascular aortic repair of aortic pathologies has become widely spread among vascular surgeons. Much focus has been directed at perfecting and developing endovascular procedures to treat evermore-complex issues. Much less focus has been directed at the radiation hazards to patients as well as operators and staff when such procedures are performed. Radiation exposure must be used according to th

Treatment of Uncertainty in Risk Based Regulations and Standards for Risk Analysis

The role of quantitative risk analysis as a foundation for decision making, regarding hazardous activities and establishments, has gained increased importance during the last decades. When performing a quantitative risk analysis, a wide range of uncertainties will inevitably be introduced during the process. The impact of these uncertainties must somehow be addressed if the analysis is to serve as

Comparison of antibody assays for detection of autoantibodies to Ro 52, Ro 60 and La associated with primary Sjögren's syndrome.

Anti-Ro(52/60) and anti-La constitute the hallmark autoantibodies in primary Sjögren's syndrome, being present in 40-70% of sera. Several anti-Ro/La assays exist, but antibody detection appears to be assay-specific, thus the aim of this study was to compare several anti-Ro/La assays. In total, 96 sera from individuals with primary Sjögren's syndrome and 114 healthy controls were tested for anti-Ro

Växandets gestaltning i Peter Pohls romansvit om Micke

Popular Abstract in Swedish "Växandets gestaltning i Peter Pohls romansvit om Micke" behandlar barndomsskildringarna "Regnbågen har bara åtta färger" (1986) och "Medan regnbågen bleknar" (1989) samt ungdomsromanerna "Vilja växa" (1994), "Vi kallar honom Anna" (1987) och "Klara papper är ett måste" (1998). Till sviten förbinds sagor ur "De Stora Penslarnas Lek" (1989) och dikter ur "Minns det" (199Peter Pohl was born in Germany in 1940 but grew up in Stockholm, a setting reflected in many of his books. Pohl, a researcher at the Royal Technical University in Stockholm, made his fiction debut with the multi-prize-winning novel "Janne, min vän" (1985), and is internationally acclaimed for, among other things, the way in which his teenage novels highlight existential questions. The purpose of t

Spelet på fältet: relationen mellan ämnet idrott och hälsa i gymnasieskolan och idrott på fritiden

This study deals with physical education (PE) in secondary school. The purpose of the study is to analyze the relationship between PE in secondary schools and leisure time sports. Questions were directed towards discovering what PE teachers recognise as valuable in their teaching, and how physical education is related to factors that characterize the field of sports. The teaching practice of Physi

Dynamic covariation between gene expression and proteome characteristics.

Cells react to changing intra- and extracellular signals by dynamically modulating complex biochemical networks. Cellular responses to extracellular signals lead to changes in gene and protein expression. Since the majority of genes encode proteins, we investigated possible correlations between protein parameters and gene expression patterns to identify proteome-wide characteristics indicative of

Temperature dependence of misfit strains of β-hydrides of zirconium

The misfit strains of both the isotopic forms of zirconium hydrides, viz., δ-ZrHx and δ-ZrDx, precipitated in zirconium were computed in the temperature range of 298–773 K and for 1.5 ≤ x ≤ 1.7, using the methodology proposed by Carpenter. Misfit strains along (0 0 0 1) plane and normal to it were observed to increase with increase in temperature for both the isotopic forms of hydrides. For a give

Findings in multi-detector row CT with portal phase enhancement in patients with mesenteric venous thrombosis.

There exists no systematic evaluation on the findings in multi-detector row computed tomography (MDCT) with portal phase enhancement in patients with mesenteric venous thrombosis (MVT). Patients with MVT between 2004 and 2006 were identified at Malmö University Hospital, Sweden. Thirty patients had MVT. Median age was 58 years (interquartile range, 46-72), and 57% (17) were men. MDCT with portal p

Sensor-augmented pump therapy lowers HbA(1c) in suboptimally controlled Type 1 diabetes; a randomized controlled trial.

Aims To investigate the efficacy of sensor-augmented pump therapy vs. multiple daily injection therapy in patients with suboptimally controlled Type 1 diabetes. Methods In this investigator-initiated multi-centre trial (the Eurythmics Trial) in eight outpatient centres in Europe, we randomized 83 patients with Type 1 diabetes (40 women) currently treated with multiple daily injections, age 18-65 y

Thyroid-Associated Ophthalmopathy after Treatment for Graves' Hyperthyroidism with Antithyroid Drugs or Iodine-131.

Context: Previous randomized trials have suggested an association between radioiodine treatment for Graves' hyperthyroidism and thyroid-associated ophthalmopathy (TAO). Objectives: The aim of the study was to compare the occurrence of worsening or development of TAO in patients who were treated with radioiodine or antithyroid drugs. Design: We conducted a randomized trial (TT 96) with a follow-up
