Majoriteten av iranierna i Sverige reser ofta till Iran, vilket gör att de enkelt är måltavlor för den islamiska regimen som kan använda sig av dem för att samla in information om andra iranier i Sverige, skriver Ardavan Khoshnood.

I TV-programmet »Uppdrag granskning« påstods nyligen (16 mars 2004) att det är livsviktigt för patienter med akut hjärtinfarkt att bo i närheten av rätt sjukhus. Frågan är när geografiska skillnader i dödlighet blir så pass stora och säkra att de har betydelse för den enskilda patienten. När man studerar skillnader i dödlighet mellan olika sjukhus bör man om möjligt också beakta landstingens roll.

The t(6;9) translocation is found in a subset of patients with acute myeloid leukemia (AML) and is associated with a poor prognosis. The translocation results in the formation of the DEK-NUP214 fusion protein containing almost the entire nuclear protein DEK and two thirds of the nucleoporin NUP214. The molecular mechanisms behind the leukemic conversion of cells expressing the fusion protein DEK-N

Defective insulin secretion is a central feature in diabetes mellitus and results from reduced pancreatic beta-cell mass as well as aberrant beta-cell function. The pathophysiology of diabetes is incompletely known, but a strong hereditary component is suggested. This thesis investigates the genetic and cellular basis for impaired insulin release by employing a number of cell-physiological and bio

This PhD thesis consists of four separate papers. What these papers have in common is that Bayesian Econometrics, in combination with Markov chain Monte Carlo (MCMC) methods, is applied to study various problems in financial economics. The first two papers are further related in that they both deal with portfolio selection and estimation risk, as are the last two papers in that they both deal with

The search for an enzyme as a reagent for selective bioanalytical detection of the neurotoxic amino acid, beta-N-oxalyl-L-,alpha,beta-diaminopropionic acid, beta-ODAP (found in grass pea, Lathyrus sativus) led to its redox catalytic reaction by glutamate oxidase (GluOx). Homogeneous kinetic studies and an immobilized GluOx reactor-based flow-injection assay were initially made for beta-ODAP with s

This thesis considers models for describing high energy particle collisions. Existing phenomonological models are modified and new implementations made in order to achive a better description of states with several hard jets. To predict final state hadrons, parton showers are used together with pheonomenological hadronization models. These models describe a wide range of observables, but have the

Major Intrinsic Proteins (MIPs, also called Aquaporins, AQPs) are channel forming membrane proteins. Although initially functionally characterized and named after their water channeling property in human red blood cells, it has become increasingly evident that MIPs are present in all types of organisms and transport a variety of small, uncharged molecules besides water. MIPs have a highly conserve

This doctoral thesis has signal processing of eye-tracking data as its main theme. An eye-tracker is a tool used for estimation of the point where one is looking. Automatic algorithms for classification of different types of eye movements, so called events, form the basis for relating the eye-tracking data to cognitive processes during, e.g., reading a text or watching a movie. The problems with t

Popular AbstractI takt med att svenska företag har ökat sina utlandssatsningar med bland annat direktinvesteringar på utländska marknader har också efterfrågan av internationell rörlighet bland den svenska kvalificerade arbetskraften ökat. En del av detta behov rör tidsbegränsade utlandsposteringar av svensk arbetskraft på så kallade ’expats-kontrakt’. Ofta utgår samhällsdebatten från en uppfattni

The field of computer graphics refers to the use of computers to generate realistic-looking images from virtual scenes. Graphics processing units use an algorithm known as rasterization to compute images of scenes viewed from a virtual camera. The commonly used pinhole camera model does not account for the imperfections that stem from the physical limitations in real-world cameras. This includes,

2022 has not been a good year for Facebook (Meta) so far. The stock price is plunging, the company is still under fire for the extent of misinformation on the platform, and the number of users are decreasing for the first time in the US. Marketing and technology analysts are speculating whether Facebook reached its peak and began losing the competition against other rising platforms like TikTok.Ye

Gender-fair language planning aims to increase linguistic inclusion of underrepresented groups, for example by using paired pronouns (he/she) instead of generic masculine forms (he). However, using paired binary forms might evoke a normative gender bias where words lead to stronger associations to individuals with normative gender expressions than to individuals with non-normative gender expressio

In a long-term prospective follow-up in patients randomized to an ileal or colonic conduit, with implantation of one ureter using antireflux technique and the other without, the fall in the mean total GFR exceeded the expected age-related decline. The fall in the mean separate GFR did not differ between refluxing and antirefluxing anastomosis. Patients with a continent caecal reservoir (antireflux

This thesis describes the development and selected applications of a global vegetation model, BIOME4. The model is applied to problems in high-latitude vegetation distribution and climate, trace gas production, and isotope biogeochemistry. It demonstrates how a modeling approach, based on principles of plant physiology and ecology, can be applied to interdisciplinary problems that cannot be adequa
