A text in channel coding, decoding algorithms, and compression of data and speech, designed for both classroom and research use. There is a special emphasis on the algorithms employed in the field.

Background. HIV-infected mothers can transmit their infection to their children in utero or at delivery (vertical transmission). There have been cases of children who were reported as acquiring infection vertically and later clearing the infection. We report the frequency of this phenomenon in a European cohort study. Methods. In four centres of the European Collaborative Study of children born to

The characterization of naturally occurring mutations is one way to approach functionally significant domains of polypeptides. About 10 mutations have been reported in factor XIII (FXIII) A-subunit deficiency, but very little is known about the effects of the mutations on the expression or the structure of this enzyme. In this study, the recent crystallization of FXIII A-subunit and determination

Vertical InAs/GaSb nanowire TFETs with diameters of 20 nm and 25 nm have been fabricated and characterized. The influence of diameter, gate-placement, and nanowire numbers have been studied. The best device shows a subthreshold swing of 68 mV/dec at VDS = 0.3 V and 26 μA/μm at VDS = 0.3 V and VGS = 0.5 V. It achieves a self-gain larger than 100 with high transconductance efficiency.

The objective of this study was to describe the natural history of HIV-1 RNA load in vertically HIV-1-infected children. HIV-1 RNA in 156 plasma or serum samples (1-14, median 4 from each child) from 32 vertically HIV-1-infected children was detected with the NASBA® technique (Organon Teknika, The Netherlands). Twenty-one children were prospectively followed from birth, and 11 were identified and

To summarize, prophylactic treatment of hemophilia begun at an early age has been gaining acceptance as the optimal therapeutic option in an increasing number of hemophilia centers in the developed world in recent years. In all too many parts of the world, however, this option must be viewed as a long-range goal in hemophilia care, since national economic resources are insufficient for regular pro

The actual reproductive choices made by slightly over a quarter of all the carriers of severe or moderate haemophilia in Sweden were investigated and compared with those of a randomly selected age-matched group of women who were not carriers of haemophilia. In general, the 105 carriers had the same number of children as other women of similar age. However, carriers who did not choose prenatal diag

Purpose: We present clinical and laboratory data on 18 children from 12 hemophilia treatment centers in the United States, Canada, and Europe with the purpose of disseminating information regarding a recently recognized, potentially life-threatening complication of treatment in very young children with hemophilia B. Patients and Methods: Twelve hemophilia centers from the United States, Canada, an

Human activities have been marred for ages by conflicts of interest. This is no less true in the field of science. In the early years of the Nobel Prizes, little attention was focused on this aspect, but awareness steadily grew. In particular, this concerned Swedes nominated for Nobel Prizes, who were most likely themselves members of the Royal Swedish Academy of Sciences, but whose fellows at the

The aim of the study was to investigate the feasibility of optimizing prophylactic dosing of factor VIII by the use of individual pharmacokinetic data. Twenty-one patients were enrolled in a randomized cross-over study on standard dosage regimens vs. dosing according to pharmacokinetic principles. The study period was 2 x 6 months. Using single-dose pharmacokinetic data for each patient, plasma fa

We demonstrate an artificial three-dimensional (3D) electrical active human neuronal network system, by the growth of brain neural progenitors in highly porous low density electrospun poly-ε-caprolactone (PCL) fiber scaffolds. In neuroscience research cell-based assays are important experimental instruments for studying neuronal function in health and disease. Traditional cell culture at 2D-surfac

The main focus of the work presented in this thesis is on experimental studies oflaser acceleration of protons and other positive ions from solid targets. The topic is explored from three different angles: firstly, the development of diagnostics adapted to the ion pulses, secondly, the characterization of the source of the energetic particles and, finally, the application of laser-accelerated prot

The performance of X-ray and neutron grating interferometers is characterised by their visibility, which is a measure for the maximum achievable contrast. In this study we show how the real grating geometry in a grating interferometer with three gratings impacts the interference and self projection that leads to visibility in the first place. We quantify the individual contributions of wavelength

In his study of Carl Michael Bellman literary historian Gustaf Ljunggren (1823-1905) compared the Swedish poet not only to the traditional object of comnaprison, the ancient Greek poet Anacreon, but also to the Persian fourteenth-century poet Hafiz.This article revisits Ljunggren's work in light of recent discussions about world literature and the role of historical scale in literary studies.

Introduction The Göttingen minipig is a promising model for pharmacological safety assessment and for translational research in cardiology. We have examined the main ion currents in cardiomyocytes of the minipig heart. Methods Cardiac cells were isolated from different cardiac regions (endo-, mid- and epicardial left ventricle and right ventricle) from Göttingen minipigs and examined using the who
