A theoretical and experimental analysis of iterative decoding of low-density convolutional (LDC) codes is given. Two families are investigated: homogeneous LDC codes and a convolutional code version of turbo-codes.

PURPOSE OF REVIEW: Moraxella catarrhalis is an emerging human-specific pathogen responsible for upper and lower respiratory tract infections. Understanding the events in the complex pathogenesis and underlying mechanisms during M. catarrhalis infection is a key to the development of novel therapeutics and vaccines. RECENT FINDINGS: Several novel findings have been reported on Moraxella pathogenesi

Kommentarer och bakgrund till faksimilutgåva av den lundensiska studentpublikationen "Hej!!!" (1892).

How are public spaces regulated in tourist cities? In this doctoral dissertation I seek to answer this question by exploring the intersections between urban tourism and public space regulation. I argue that public space regulation substantially differs from the tourist to the non-tourist zone. This thesis contradicts the common belief that public space regulation may vary from city to city, but re

Background: The safety and efficacy of the Promus Element stent have been recently demonstrated in a selected population from one randomized trial. The aim of this study was to describe the initial clinical experience with the everolimus eluting platinum chromium stent (Promus Element) in unselected patients from a real life nationwide registry. Methods: The Promus Element DES was compared to all

Lung scintigraphy is primarily used to diagnose pulmonary embolism. Ventilation imaging is often performed using Tc-99m-DTPA or Technegas, an ultrafine dispersion of Tc-99m-labeled carbon. Despite the common use of these radioaerosols, they have not been compared in an intraindividual study, and not with ventilation-perfusion (V/P) SPECT. The aim of the present head-to-head study was to systematic

A robust and stable film comprising n-octylpyridinum hexafluorophosphate ([C8Py][PF6]) and 1:12 phosphomolybdic acid (PMo12) was prepared on glassy carbon electrodes modified with multiwall carbon nanotubes (GCE/MWCNTs) by dip-coating. The cyclic voltammograms of the GCE/MWCNTs/[C8Py][PF6]-PMo12 showed three well-defined pairs of redox peaks due to the PMo12 system. The surface coverage for the im

Nowadays, the same piece of code should run on different architectures, providing performance guarantees in a variety of environments and situations. To this end, designers often integrate existing systems with ad-hoc adaptive strategies able to tune specific parameters that impact performance or energy—for example, frequency scaling. However, these strategies interfere with one another and unpred

Only a minority of patients treated with antipsychotics in clinical studies continue their treatments throughout a longer study period. Few studies address this issue from a lifetime perspective. In this naturalistic study, we aimed at analysing the prescription pattern of antipsychotic drugs among a sample of Swedish patients with a diagnosis of psychotic illness, from the first contact with psyc

A strongly coupled dipolar fluid confined in a sphere has been examined by Monte Carlo simulations using a modified distance-dependent pair interaction to emulate retardation effects. The effective dipole-dipole interaction and a property closely related to Kirkwood's g-factor have been analyzed for potentials with different distances at which the retardation effects became effective. The retardat

Complex hydrides are very promising candidates for future light-weight solid state hydrogen storage materials. The present work illustrates detailed characterization of such novel hydride materials on different size scales by the use of synchrotron radiation and neutrons. The comprehensive analysis of such data leads to a deep understanding of the ongoing processes and mechanisms. The reaction pat
