Many stream ciphers use irregular clocking to introduce nonlinearity to the keystream. We present three distinguishers on irregularly clocked linear feedback shift registers. The general idea used is to find suitable linear combinations of keystream bits, here called samples, that are drawn from a biased distribution. We describe how to place windows around the estimated positions around members

Sexual health problems are common for women with Rheumatoid Arthritis, RA. Sexual health is covered in the International Classification of Functioning, Disability and Health (ICF) by two different fields: sexual function and intimate relationships, which are included in the ICF core sets for RA. Most patients with RA are female, and there are differences concerning sexual health between women and

Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING Smärtor i övre högra delen av buken och/eller gulsot är de mest vanliga symptomen relaterade till lever och gallvägssjukdomar. Den vanligaste orsaken till gallvägssjukdom är sten i gallblåsa och gallvägar som kan leda till inflammation av gallblåsa, gallvägar, lever och bukspottkörtel. Andra sjukdomar är tumörer i nämnda organ. SymptomThe diagnostic value of modern fast pulse sequences and breath-hold technique was evaluated in a prospective study of patients with suspected biliary diseases. The cost-effectiveness of MRI compared to ultrasound was calculated. Characteristics of acute cholecystitis and cholangitis were evaluated, the appearance of bile in MRCP with reference to its chemical and physical properties was studied, a

In this thesis I investigate genetic variation in clonal plants within the wind-pollinated plant family Cyperaceae and, in particular, in species of Carex. Clonal diversity and the spatial distribution of clones (genets) within populations was investigated in Carex bigelowii (in Iceland and Scandinavia) and C. arenaria (within the species' entire distributional range in W Europe). Both species re

Popular Abstract in Swedish 1: Tomas Åkerud, doktorand vid Lunds Universitet, har utvecklat en metod för att mäta hur snabbt läkemedelsmolekyler och fettsyror (de naturliga bindarna) tar sig in i och lämnar bindingsfickan i ett protein som är viktigt för fettsyrametabolismen i människa. Proteinet, adipocyt-fettsyrabindande protein (A-FABP), har som funktion att transportera fettsyror, som inte är Nuclear magnetic resonance spectroscopy (NMR) has been used to determine the kinetics of ligand binding to the adipocyte fatty acid-binding protein (A-FABP), as well as the oligomerisation and inter- and intramolecular dynamics of the low molecular weight-protein tyrosine phosphatase (LMW-PTP) in solution. NMR spectroscopy is sensitive to dynamic processes on timescales ranging from picoseconds t

We studied in chimeric EGFP-Photinus luciferase HeLa cells the expression of fluorescence and luminescence in different cell culture conditions (medium with or without Serum, static or dynamic conditions, in suspension or on microcarriers) as a model to follow the productivity of a recombinant protein. By studying the effect of Butyrate known as general but unpredictable stimulating agent for prot

The number of electrically driven loads in a modern vehicle is constantly increasing. Many loads that former were mechanically driven will in the future be driven by electricity. This implies that a number of electronic systems have to be packed together in the limited space in a vehicle. When different electronic systems are placed close to each other, there is always a risk for electromagnetic i

The aim of this thesis was to elucidate the mechanisms by which planktivorous fish can affect planktonic communities in lakes and how they may affect benthic communities through their effects on planktonic communities. In a laboratory experiment, nutrients released by fish increased algal biomass and altered phytoplankton community structure, suggesting that fish can affect phytoplankton by direct
