We consider model predictive control (MPC) problems with linear dynamics, polytopic constraints, and quadratic objective. The resulting optimization problem is solved by applying an accelerated gradient method to the dual problem. The focus of this paper is to provide bounds on the number of iterations needed in the algorithm to guarantee a prespecified accuracy of the dual function value and the

Recent finds of the leafcutting bee Megachile lagopoda (Linnaeus) in Åhus, Scania in Southern Sweden are presented. This species has drastically decreased in Sweden since 1970, and is now considered vulnerable (VU) on the Swedish redlist.

This article is concerned with the correlation between credibility and the concept of sovereignty in international law and their relationship to truth. Empirically, the authors focus on the credibility assessment informing the refugee determination procedure operated by the Office of the UN High Commissioner of Refugees. The authors do not provide a rationalised explanation of credibility assessme

Context. A long-held vision has been to realize diffraction-limited optical aperture synthesis over kilometer baselines. This will enable imaging of stellar surfaces and their environments, and reveal interacting gas flows in binary systems. An opportunity is now opening up with the large telescope arrays primarily erected for measuring Cherenkov light in air induced by gamma rays. With suitable s

Autoantibodies against the newly established autoantigen in type 1 diabetes, zinc transporter 8, ZnT8, are presented as two types, ZnT8RAb and ZnT8WAb. The rs13266634 variant of the SLC30A8 gene has recently been found to determine the type of ZnT8Ab. The aim of this study was to explore the impact of this genetic variant and the ZnT8Ab on the residual beta-cell function during disease progression

Specific parameters of the neuronal tissue microstructure, such as axonal diameters, membrane permeability and intracellular water fractions are assessable using diffusion MRI. These parameters are commonly estimated using analytical models, which may introduce bias in the estimated parameters due to the approximations made when deriving the models. As an alternative to using analytical models, a

Type 2 diabetes (T2D) is a disease characterised by varying degrees of defect in insulin secretion and insulin sensitivity and associated with increased morbidity and mortality. Optimal glycaemic control reduces the progression of diabetic complications. Over time, there is a steady deterioration of glycaemic control that raises the need for effective therapy targeted at the underlying defects in

Objective . To evaluate the clinical performance in a paediatric population of the Lund-Malmo creatinine-based glomerular filtration rate (GFR) prediction equations, primarily developed for adults. Material and methods . Iohexol clearance was used as the gold standard in 85 paediatric Caucasian patients (0.3-17 years; 37 F/48 M). One Lund-Malmo equation was based on age and gender (LM) and one inc

In this paper a particular case of grammatical gender agreement system is discussed, concerning the referent of young females or small children. These referents are grammatically treated as neuter nouns, disregarding their biological sex. This is termed gender disagreement. It is argued here that this is due to the older classification of nouns based on active and inactive distinction, stemming fr

This correspondence deals with the construction of minimum Euclidean distance precoders for multiple-input multiple-output (MIMO) systems with up to four transmit antennas. By making use of a state-of-the-art technique for optimization over the unitary group, we can numerically optimize the MIMO precoders. The correspondence then proceeds by identifying the obtained precoders as well-known lattice

Background: To offer minimized risk-adapted adjuvant treatment on a community and nationwide basis for patients with clinical stage 1 (CS1) nonseminomatous germ-cell testicular cancer (NSGCT). The aim was to reduce the risk of relapse and thereby reducing the need of later salvage chemotherapy while maintaining a high cure rate. Patients and methods: From July 1995 to January 1998, a total of 232

This randomized clinical trial assessed the effectiveness of multisystemic therapy (MST) for 156 youths who met the diagnostic criteria for conduct disorder. Sweden's 3 largest cities and I small town served as the recruiting area for the study. A mixed factorial design was used, with random allocation between MST and treatment as usual groups. Assessments were conducted at intake and 7 months aft

Mature aggrecan is generally C-terminally truncated at several sites in the CS (chondroitin sulfate) region. Aggrecanases and MMPs (matrix metalloproteinases) have been suggested to be responsible for this digestion. To identify whether calpain, a common intracellular protease, has a specific role in the proteolysis of aggrecan we developed neoepitope antibodies (anti-PGVA, anti-GDLS and anti-EDLS

The lectin, phytohaemagglutinin (PHA), from red kidney beans has been shown as an inducer of growth and precocious gastrointestinal (Cl) maturation in suckling animals, thus better preparing piglets for the weaning procedure. PHA exposure results in the release of gut peptide hormones and/or activation of the Cl immune system. The aim of this study was to elucidate the mechanisms of PHA provocatio

Popular Abstract in Swedish Skador i knäleden är vanligt förekommande och främre korsbandsskada drabbar i Sverige årligen mer än 8 per 10 000 personer i åldern 10-64 år. Följderna av skadan kan bli bestående funktionsnedsättning med bl.a. instabilitet, plötsliga och smärtsamma knäledsvikningar och ökad risk för nya skador. Cirka hälften av patienterna utvecklar ledsvikt (artros) 10-15 år efter denThe purpose of this thesis was to increase the understanding of altered movement patterns in individuals with anterior cruciate ligament (ACL) injury in order to improve ACL rehabilitation, and to develop an observational instrument termed Test for Substitution Patterns (TSP) for standardized, quantifiable scoring of altered movement patterns in legs and trunk. In all, 142 participants, 93 with A

A search for long-lived particles is performed using a data sample of 4.7 fb(-1) from proton-proton collisions at a centre-of-mass energy. root s = 7 TeV collected by the ATLAS detector at the LHC. No excess is observed above the estimated background and lower limits, at 95% confidence level, are set on the mass of the long-lived particles in different scenarios, based on their possible interactio

This study compares the children and adult response to a novel postural challenge. One group of children (n = 13, age 7-9) and one adult reference group (n = 12 age 15-32) were subjected to vibration induced body sway and posturography with both open and closed eyes for 5 consecutive days. There was a gradual decrease of induced body sway over time in both groups (p < 0.001) between the subsequent
