Most works published on iterative CDMA receivers assume perfect channel knowledge or very simple channel models like the flat-fading channel. We want to extend the scope to multipath propagation scenarios and suggest an iterative scheme with channel estimation in the uplink of a chip-synchronous CDMA system. Channel estimates rely on pilot symbols and a posteriori probabilities on code bits of a S
We evaluated the influence of the brown rot fungus Hygrophoropsis aurantiaca on P solubility in the humus layer of a podzolic forest soil. This fungus is known to exude large amounts of oxalic acid that may stimulate weathering of minerals and increase dissolution of humus, which in turn may increase P availability in the soil surrounding the fungus. Humus was inoculated using small wooden pieces
Background: Body weight and body mass index (BMI) are positively related to risk of colon cancer in men, whereas weak or no associations exist in women. This discrepancy may be related to differences in fat distribution between sexes or to the use of hormone replacement therapy (HRT) in women. Methods: We used multivariable adjusted Cox proportional hazards models to examine the association betwee
This study was performed to evaluate if microarray technology can identify genes using their transcriptionally defective mutant alleles. Three barley (Hordeum vulgare L.) mutant strains, xantha-h57, xantha-f27 and xantha-g28, with mutations in the genes encoding the three subunits of the chlorophyll biosynthetic enzyme magnesium chelatase, were used in a reconstruction experiment. The mutation xan
Introduction: The study tested whether four commonly used patient-rated outcomes are explained by only one factor, reflecting a general appraisal tendency of patients. Method: Quality of life, needs and symptoms were rated by 92 patients in community mental health care at baseline and after 18 months and 6 years follow-up periods. At follow ups treatment satisfaction was also assessed. Scores and
Objective To compare sonographic endometrial characteristics in in-vitro fertilization (IVF) cycles between women who conceive and those who do not. Methods Thirty-five women undergoing IVF treatment participated in the study. Using three-dimensional (3D) power Doppler ultrasound, we assessed endometrial patterns, volume and vascularization, after follicle stimulating hormone (FSH) stimulation but
The MLL gene in chromosome band 11q23 is frequently rearranged in acute lymphoblastic and acute myeloid leukemias. To date, more than 50 different chromosomal regions are known to participate in translocations involving 11q23, many of which affect MLL. The pathogenetically important outcome of these rearrangements is most likely the creation of a fusion gene consisting of the 5' part of the MLL ge
Background Because of current cost restrictions, we studied the effect of a shorter hospital stay on function, pain and quality of life (QOL) after total hip replacement (THR). Patients and methods 50 patients from two hospitals were randomized into a study group (SG) of 27 patients receiving preoperative and postoperative education programs, as well as home visits from an outpatient team, and a c
Most patients referred to physiotherapy with low back pain are without a precise medical diagnosis. Identification of subgroups of non-specific low back pain patients may improve clinical outcomes and research efficiency. A pathoanatomic classification system has been developed, classifying patients with non-specific low back pain into 12 different syndromes and three subcategories based on histor
Essay regarding current debates in Sweden about the various functions of art criticism in relation to the public sphere. Language: Swedish.
Play audiometry is part of the general developmental screening covering 4-year-old children in the city of Malmo (Sweden). In an open study, 10% of the cohort was tested with transient-evoked otoacoustic emissions (TEOAEs), using the ILO88 system. The aim was to reveal a hearing loss exceeding 25 dB HL in 4-year-old children. As the first step in determining whether emissions can be used as an eff

Background. During pregnancy and parturition a remodeling within the extracellular matrix of the cervix and the corpus uteri occurs, which is of fundamental importance to a normal labor. The aim of this study is to identify the major proteoglycans in corpus uteri of non-pregnant subjects. Methods. From human uterine tissue proteoglycans were extracted and purified using CsCl-density gradient centr
Prompt proton decay lines in Cu-58 have been studied by means of high-resolution in-beam particle-gamma coincidence spectroscopy using the GAMMASPHERE Ge-detector array in conjunction with a dedicated set of ancillary detectors including four DeltaE-E silicon-strip telescopes. High-spin states in Cu-58 have been populated via the heavy-ion fusion-evaporation reaction Si-28(Ar-36, 1alpha1p1n) at 14
