We analyze the impact of mutual coupling on the capacity of MEMO systems with compact antenna arrays. Existing studies present conflicting views on the effect of mutual coupling. This is, in part, due to their different scopes and underlying assumptions of the system setups. In this paper, we aim to give a comprehensive picture by first examining the impact of mutual coupling on three capacity-rel
Popular Abstract in Swedish En god näringstillförsel är viktigt för att ett barn ska växa och utvecklas tillfredställande. De första 2-3 åren innebär en kraftig tillväxt och optimalt kostintag är därför extra viktigt under denna perioden. Barnets vikt tredubblas först året och längden ökar med 50 %. Hjärnan har en kraftig tillväxt de första 3 åren. Således är näringsbehoven relativt sett störst deThe overall aim of this thesis was to describe the prevalence of iron deficiency (ID) and factors influencing iron status and iron intake among otherwise healthy children. The specific aim in paper I+II was to describe the prevalence of ID among 2 ½-year-old children in relation to intake of cow's milk and follow-on formula. The design in the first two papers were cross-sectional and 367 2 ½-year-
The development of new binders used for coatings has traditionally been driven by a combination of the need for technical improvements and increased environmental awareness, together with stricter legislation regarding VOC (volatile organic compound) emissions. One interesting way to achieve new types of binders is to combine already existing ones, thereby exploiting the positive properties of bot
Solving the simplified model of the Hartree-Fock Bogoliubov equation in coordinate space with the correct asymptotic boundary conditions, the spin-orbit splitting, occupation probabilities, effective pair-gap, mean square radius, and spin-response function are studied for weakly bound p neutrons. As the binding energy of p3∕2 neutrons becomes small or approaches zero, the spin-orbit splitting p3∕2
A constitutive model for diffusionless phase transitions in elastoplastic materials undergoing large deformations is developed. The model takes basic thermodynamic relations as its starting point and the phase transition is treated through an internal variable (the phase fractions) approach. The usual yield potential is used together with a transformation potential to describe the evolution of the
BACKGROUND: Markedly decreased or absent gastric acid production is associated with a number of clinically significant conditions, and identification of patients with hypo/achlorhydria may be important. However, current methods of assessing impaired acid secretion are unreliable, time-consuming, and/or complex. The aim of this prospective study was to evaluate a modified endoscopic Congo red test
Popular Abstract in Swedish En av hjärnans mest fascinerande egenskaper är dess förmåga att ständigt anpassa sig till nya utmaningar och förändringar i den yttre eller inre miljön. Denna formbarhet, eller plasticitet, sker på olika nivåer från små förändringar på molekylnivå till antalet av eller styrkan i förbindelser mellan nervceller och mängden transmittorsubstans de utsöndrar. De senaste deceNew neurons are spontaneously generated in two regions of the adult brain, the hippocampus and the subventricular zone/olfactory bulb. The objective of this thesis was to study potential implications for adult neurogenesis in Alzheimer's (AD) and Parkinson's diseases (PD). PD is characterized by degeneration of dopaminergic neurons in the substantia nigra. It has been suggested that new dopaminer
Together with its ligand, stem cell factor, the receptor tyrosine kinase c-Kit is a key controlling receptor for a number of cell types, including hematopoietic stem cells, mast cells, melanocytes and germ cells. Gain-of-function mutations in c-Kit have been described in a number of human cancers, including testicular germinomas, acute myeloid leukemia and gastrointestinal stromal tumors. Stimulat
Affinity proteins were covalently immobilised on silicon microchips with overall dimensions of 13.1 x 3.2 mm, comprising 42 porous flow channels of 235 mum depth and 25 pm width, and used to develop microfluidic immunosensors based on horseradish peroxidase (HRP), catalysing the chemiluminescent oxidation of luminol/p-iodophenol (PIP). Different hydrophilic polymers with long flexible chains (poly
The possibility to simulate lepton number violating supersymmetric models has been introduced into the recently updated Pythia event generator, now containing 1278 decay channels of SUSY particles into SM particles via lepton number violating interactions. This generator has been used in combination with the AtlFast detector simulation to study the impact of lepton number violation (4) on event to
Concerns over the threats of terrorism, piracy, and armed robbery against ships resulted in a number of International Maritime Organization (IMO) initiatives in the 1980s and 1990s including, inter alia, the establishment of an anti-piracy program, the development of guidelines for ship security, and the adoption of the Convention for the Suppression of Unlawful Acts Against the Safety of Maritime
After infection with Borrelia burgdorferi, humans and mice under certain conditions develop arthritis. Initiation of inflammation is dependent on the migration of innate immune cells to the site of infection, controlled by interactions of a variety of adhesion molecules. In this study, we used the newly synthesized compound S18407, which is a prodrug of the active drug S16197, to analyze the funct
