Two constructions of binary concatenated convolutional codes are considered. In our previous work [Proc. 4th Int. Symp. Commun. Theory Appl., Lake District, UK (1997)] such codes were called woven convolutional codes. In the present paper, asymptotic lower bounds on active distances of woven convolutional codes are investigated. It is shown that these distances can be bounded from below by linearl

Software for recognition of handwriting has been available for several decades now and research on the subject have produced several different strategies for producing competitive recognition accuracies, especially in the case of isolated single characters. The problem of recognizing samples of handwriting with arbitrary connections between constituent characters (emph{unconstrained handwriting})

Roads and pavements covered with ice and snow during winter in the Nordic and other cold regions are slippery, which result in the prevalence of slip and fall accidents among not only the public, but also outdoor workers. Literature and injury statistics revealed that the most frequently specified contributory factor for occupational slip, trip and fall accidents in Sweden is snow and ice. Road ac

White matter (WM) changes are frequently seen on structural imaging in AD but the clinical relevance of these changes is uncertain. Frontal WM pathology is often observed upon neuropathological examination in AD. Since frontal cortical/sub-cortical pathology is known to relate to executive dysfunction, the aim was to elucidate if frontal WM changes in AD correlated with executive dysfunction. In a

The aim of this study was to investigate whether the compression force used with conventional mammography can be reduced with breast tomosynthesis (BT), without adversely affecting the visualisation of normal and pathological structures. Forty-five women were examined with BT using full (same as for 2D mammography) and half compression force. Both examinations were performed with the same acquisit

BACKGROUND: IgA nephropathy (IgAN), the most common glomerulonephritis worldwide, is characterized by mesangial deposits containing predominantly IgA. IgAN commonly occurs or exacerbates after upper respiratory tract infections such as streptococcal pharyngitis. Certain group A streptococci express M proteins with IgA-binding regions (IgA-BRs). We have previously shown that these IgA-BRs co-locali

I. Levi has advocated a decision-theoretic account of belief revision. We argue that the game-theoretic framework of Interrogative Inquiry Games, proposed by J. Hintikka, can extend and clarify this account. We show that some strategic use of the game rules (or ‘policies’) generate Expansions, Contractions and Revisions, and we give representation results. We then extend the framework to represent

Popular Abstract in Swedish Syftet med den aktuella forskningen är att ge en bättre förståelse av förmaksflimmer, den vanligaste rytmrubbningen i hjärtat som drabbar så många som var tionde över 70 år. Mekanismerna för förmaksflimmer är långt ifrån kartlagda, vilket bland annat leder till att behandlingen är standardiserad istället för att den beror på de mekanismer som styr varje enskild patientsThis doctoral thesis is in the field of biomedical signal processing with focus on methods for the analysis of atrial fibrillation (AF). Paper I of the present thesis addresses the challenge of extracting spatial properties of AF from body surface signals. Different parameters are extracted to estimate the preferred direction of atrial activation and the complexity of the atrial activation pattern

The institutional landscape of the EU has been transformed through the establishment of agencies and changes brought by the Lisbon Treaty. This article seeks to contribute to our conceptual and empirical understanding of European agencies post-Lisbon. It maps the current European agencies according to timing of establishment, size, functions, governance structures and financial arrangements, and d

Scand J Caring Sci; 2009 Utilization of medical healthcare among people receiving long-term care at home or in special accommodation Aim: To investigate the utilization of medical healthcare, hospital care and outpatient care, during a 1-year period in relation to informal care, multimorbidity, functional status and health complaints and to long-term care at home or in special accommodation among

Cutaneous human papillomaviruses (HPV) are common in nonmelanoma skin cancers, benign skin lesions, and healthy skin. Increased seroprevalences for cutaneous HPV among nonmelanoma skin cancer patients have been described. To determine whether antibodies to cutaneous HPV are related to presence of the virus and/or to skin disease, we collected serum and biopsies from both lesions and healthy skin f
