When searching for convolutional codes and tailbiting codes of high complexity it is of vital importance to use fast algorithms for computing their weight spectra, which corresponds to finding low-weight paths in their code trellises. This can be efficiently done by a combined search in both forward and backward code trees. A bidirectional efficient algorithm for searching such code trees (BEAST)

The present work is one of nine parts making up the archaeological project The Öresund Fixed Link. The book begins with an account of all the features and artefacts that are considered to have belonged to the ideological sphere within the project. The focus is on two sites, one located on the coast, the other in the outer hummocky landscape. As regards remains on the coast, this work concentrates

The possibilities and limitations of the rediagonalization method for detection and removal of virtual interactions at bandcrossings are explored in the framework of the cranked Nilsson-Strutinsky shell model. Improvements of the method are suggested.

Modern treatment decision making in medicine is recommended to be evidence based. In order to have a high grade of evidence, the studies should have sufficient power, be randomized and double blinded. Moreover, the evaluation parameters should be solid and reproducible. While there is a lot focus on primary study design much less is focused on patient eligibility and to what extent the patients in

OBJECTIVE: To compare the neonatal outcome in planned vaginal delivery and planned cesarean section in term singleton pregnancies with breech presentation in a Scandinavian clinic with a high rate of vaginal breech delivery. METHODS: A retrospective study including 1050 term singleton breech pregnancies delivered at a Swedish tertiary referral center during 1988 to 2000. For 699 patients (67%) a v

During the last decades (-)-deprenyl has become the golden standard of MAO-B inhibitors. It possesses dopamine potentiating and antioxidant properties; however, its effects cannot be explained solely by the enzyme inhibitory action. (-)-Deprenyl prevents the toxicity of certain selective neurotoxins and recently it was demonstrated to increase cell-cell adhesion as well. The complexity of its phar

OBJECTIVE. To ascertain whether carotid intraplaque haemorrhage (IH) in patients undergoing carotid artery surgery is a predictor of increased cardiac mortality over a 5.5 year follow-up. DESIGN AND SUBJECTS. Carotid artery plaques were obtained at surgery from 47 consecutive patients (41 men, six women), median age 67 (range 48-81) years, with symptoms of carotid transient ischaemic attacks (TIAs

Streptococcus pyogenes, the most significant streptococcal species in clinical medicine, expresses surface proteins with affinity for several human plasma proteins. Here we report that kininogens, the precursors to the vasoactive kinins, bind to the surface of S. pyogenes. M protein, a surface molecule and a major virulence factor-in these bacteria, occurs in > 80 different serotypes. Among 49 str

BACKGROUND: Bilharzia-associated bladder cancer (BAC) is a major health problem in countries where urinary schistosomiasis is endemic. Characterization of the genetic alterations in this cancer might enhance our understanding of the pathogenic mechanisms of the disease but, in contrast to nonbilharzia bladder cancer, BAC has rarely been the object of such scrutiny. In the present study, we aimed t

Intellectual capital has gained increasing attention concerning both research and more practically oriented applications during the past five years. Intellectual Capital and other knowledge management tools are topics that have emerged in the light of a broader trend of redirecting the foundation of competitive advantage from the company’s tangible assets to its intangibles such as knowledge base,

A disaccharide scaffold based on galabiose (Gal1–4Gal) was synthesized. Four different acceptors were evaluated in the -galactosylation and a relationship between the nucleophilicity, yield, and /-selectivity was found. The scaffold contains two orthogonal derivatisation sites, i.e. at O-2′ and the anomeric position, and as proof of concept, one derivatised galabioside was synthesized. Compounds b
