This paper presents theory andalgorithms for system identification suitable for the framework of behavioral system theory. An algorithm basedon algebraic system theory and realization theory (Ho-Kalman realization) in a subspace model identification framework is presented. The novel approach taken consists of the formulation of input-output data as an impulse response model and the subsequent appl

The aim of this study was to develop all algorithm to automatically calculate infarct transmurality based oil a non dichotomous infarct classification, and to compare with manual delineation. Global transmurality as calculated by the computer algorithm were significantly smaller than the consensus delineation of three observers (p < 0.05). On a regional basis in 6 sectors of each slice the variabi

Weikerts doktorsavhandling i historia definierar offerkyrkor som »en kyrka som av tradition har ansetts besitta en särskild kraft, vilket gjorde att en gåva – eller offer – där ansågs öka chansen till bönhörelse». De flesta finns i Skara och Växjö stift. Sin höjdpunkt nådde offrandet under slutet av 1600-talet och början av 1700-talet. Givarnas ursprung och attityderna vid visitationer har undersö

We give some new examples of bounded multilinear forms on the Hilbert spaces l(2) and L-2(0, infinity). We characterize those which are compact or Hilbert-Schmidt. In particular, we study m-linear forms (m >= 3) on l(2) which can be regarded as the multilinear analogue of the famous Hilbert matrix. We also determine the norm of the permanent on K-n, where K = R or C.

The purpose of this article is to propose a constrained lexical semantic definition of referential metonymy within a model of meaning as ontology and construal. Due to their various types of lexical-referential pairings, 3 types of construals that are frequently referred to as metonymy in the cognitive literature are distinguished as metonymization, facetization, and zone activation. Metonymizatio

Objective. Cardia, non-cardia and intestinal and diffuse subtypes of gastric cancer may have different trends and etiological factors. However, the available information is not always collected in population cancer registries, and heterogeneous criteria have been applied for the histopathological classification of tumors. We describe the pathological features of incident gastric and esophageal can

In this paper we examine C. I. Lewis’s view on the role of coherence – what he calls “congruence” – in the justification of beliefs based on memory or testimony. Lewis has two main theses on the subject. His negative thesis states that coherence of independent items of evidence has no impact on the probability of a conclusion unless each item has some credibility of its own. The positive thesis sa

This report presents an analysis of three major fires in Sweden. Two of the fires concerns the industry and the third is a fire in a assembly hall. The study is based on available written material. The quality and reliability varies, and appears to depend on the aim, interest and competence of the investigator. In some cases, the information is sufficient to assess the performance of an automatic

The aim of the present study was to analyse quantitatively, on a cat gastrocnemius preparation in vivo, the effects of i.a. or i.v. administered glyceryl trinitrate (GTN), sodium nitroprusside (SNP) or nitric oxide (NO dissolved in saline) on vascular resistance (tone) in the following consecutive vascular sections: Large-bore arterial resistance vessels (> 25 microns), small arterioles (< 25 micr

Genetic changes underlie tumor progression and may lead to cancer-specific expression of critical genes. Over 1100 publications have described the use of comparative genomic hybridization (CGH) to analyze the pattern of copy number alterations in cancer, but very few of the genes affected are known. Here, we performed high-resolution CGH analysis on cDNA microarrays in breast cancer and directly c

Ureterostomia in situ was performed to reduce the nervous reflex activation of the bladders without concomitant hypertrophy. In muscle strips of these disused and non-hypertrophied bladders, supersensitivity to methacholine was demonstrated, which did not increase between 1 and 3 weeks. The supersensitivity did not increase further by combining urinary diversion with section of the preganglionic b
