We consider a multiple input multiple output (MIMO) system wherein channel correlation as well as noisy channel estimation are both taken into account. For a given block fading duration, pilot-assisted channel estimation is carried out with the aid of a minimum mean square error estimator. The pilot sequences and data are jointly optimized to maximize the ergodic capacity while fulfilling a total
Projektet NOA finansierades av Europeiska socialfonden (Växtkraft, Mål 3) och vände sig till långtidssjukskrivna vid Försäkringskassan i Malmö mellan åren 2005-2007. Utvärderingen av projektet har en formativ och en summativ del och bygger på intervjuer med kursdeltagare, projektledare, arbetspsykologer och outplacementkonsulter. Deltagarna beskriv utbytet av projektet på olika sätt. En del betona
Using exact dispersion relations for electromagnetic wave propagation in layered, periodic media, consisting of two phases, we derive explicit asymptotic solutions for small wavenumbers. These solutions are compared to the numerical solutions of the exact dispersion relations, and applications to homogenization problems are discussed. The results can be used as test cases for homogenization techni
A search for narrow baryonic resonances decaying into Ξ-π- or Ξ-π+ and their antiparticles is carried out with the H1 detector using deep inelastic scattering events at HERA in the range of negative photon four-momentum transfer squared 2 < Q2 < 100 GeV2. No signal is observed for a new baryonic state in the mass range 1600–2300 MeV in either the doubly charged or the neutral decay channels. The k
A method for determining transition matrices for inhomogeneous dielectric shells is presented. The source can be either inside or outside the shell. The method is based upon expansions of the electric and magnetic fields in vector spherical harmonics. The expansion coefficients in the shell satisfy a system of linear ordinary differential equations in the radial direction. The expansion coefficien
Reflektioner i text och bild kring ett tioårigt samarbetsprojekt mellan konstnärerna Inger Bergström, Elizabet Christiansson, Tarika Lennerbjörk och Maria Wahlgren. Artikeln fokuserar särskilt på konstens och forskningens hantverk utifrån utställningen Researcher in Residence på Kunstindustrimuseum 2005.
Moraxella catarrhalisis a human respiratory pathogen that causes acute otitis media in children and is associated with exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD). The first step inM. catarrhaliscolonization is adherence to the mucosa, epithelial cells, and extracellular matrix (ECM). The objective of this study was to evaluate the role ofM. catarrhalisint
Distinct tissue-specific mechanisms mediate insulin action in fasting and postprandial states. Previous genetic studies have largely focused on insulin resistance in the fasting state, where hepatic insulin action dominates. Here we studied genetic variants influencing insulin levels measured 2 h after a glucose challenge in >55,000 participants from three ancestry groups. We identified ten new lo
This communication describes a two unit antisense RNA cassette system for use in gene silencing. Cassettes consist of a recognition unit and an inhibitory unit which are transcribed into a single RNA that carries sequences of non-contiguous complementarity to the chosen target RNA. The recognition unit is designed as a stem-loop for rapid formation of long- lived binding intermediates with target
