An integrated method for clustering of QRS complexes is presented which includes basis function representation and self-organizing neural networks (NN's). Each QRS complex is decomposed into Hermite basis functions and the resulting coefficients and width parameter are used to represent the complex. By means of this representation, unsupervised self-organizing NNs are employed to cluster the data
En diskussion om historieskrivning i amerikansk film med utgångspunkt i Mats Jönssons doktorsavhandling i filmvetenskap, Film och historia. Historisk Hollywoodfilm 1960-2000.
In this study we present the genetic analysis of freshly collected garlic landraces (Allium sativum L.) along an eco-geographical transect from northeastern to western Iran covering seven different provinces using ISSR and RAPD markers. A total of 52 polymorphic loci were detected among 31 landrace populations. The percentage of polymorphic bands, the mean effective number of alleles, and the mean
A common assessment of postural control often involves subjects standing on a compliant surface, such as a foam block, to make balance tests more challenging. However, the physical properties of the foam block used by different researchers can vary considerably. The objective of this study was to provide an initial approach for investigating whether two of the foam properties, i.e. density and ela
Atherosclerosis is a chronic inflammatory disease characterized by accumulation of oxidized lipoproteins, increased cell death and hypertrophic degeneration of the arterial intima. The disease process is associated with local formation of modified self antigens that are targeted by both innate and adaptive immune responses. Although it remains to be firmly established it is likely that these autoi
Popular Abstract in Swedish Många av dagens stora folksjukdomar, såsom cancer, diabetes och hjärt-kärlsjukdomar, kopplas i allt högre grad samman med olika riskfaktorer som beror på förändringar i arvsmassan. Dessa nya kopplingar har möjliggjorts tack vare den extrema utveckling av genetiska mätmetoder som har skett under de senaste 15 åren. Med de nya metoderna kan förekomsten och aktiviteten hosThis thesis deals with methods for extracting robust and relevant information from high-dimensional data sets, and statistically guided visualization methods for representing the data in an informative and easily accessible way. High-dimensional data sets are becoming increasingly prevalent in many different scientific disciplines. In this thesis, we focus particularly on so called "omics" data. T
Venous thrombosis is a major medical problem annually affecting millions of individuals worldwide. It is a typical multifactorial disease, the pathogenesis involving both environmental and genetic risk factors. A single point mutation in the gene of coagulation factor V (FV), which results in the replacement of Arg506 with a Gln (FV Leiden) is the most common genetic risk factor known to date. The
Översättning av ett reportage från Roths resa i Sovjetunionen 1926.
Systemic or intracerebral delivery of neural stem and progenitor cells (NSPCs) and activation of endogenous NSPCs hold much promise as potential treatments for diseases in the human CNS. Recent studies have shed new light on the interaction between the NSPCs and cells belonging to the innate and adaptive arms of the immune system. According to these studies, the immune cells can be both beneficial
To evaluate relationships between lipid-lowering therapy, inflammation, and 3-year mortality in critical limb ischemia (CLI), 259 consecutive CLI patients underwent evaluation of medication, tumor necrosis factor-alpha, interleukin-6 (IL6), neopterin, high-sensitivity C-reactive protein (hs-CRP), 8-epi-PGF2alpha, and endothelin-1. Mortality was assessed after 3 years. Sixty-one patients (24%) were
A rate R=5/20 hypergraph-based woven convolu- tional code with overall constraint length 67 and constituent con- volutional codes is presented. It is based on a 3-partite, 3-uniform, 4-regular hypergraph and contains rate R=3/4 constituent convolutional codes with overall constraint length 5. Although the code construction is based on low-complexity codes, the free distance of this construction, c
Persons with a Middle Eastern background represent a minority in Sweden which has significantly increased in size over recent years. The purpose of the present study was to explore the elements that shape the experiences and perceptions of clients with a Middle Eastern background living by Muslim norms who received occupational therapy in mental health care at the time of participating in the stud
BACKGROUND.: To prepare a highly immunized recipient for heart transplantation, reduction of high levels of cytotoxic antibodies against human leukocyte antigen (HLA) was deemed essential to prevent antibody-mediated graft failure. METHODS.: Antibodies were analyzed by lymphocytotoxic and solid-phase assays. The pretransplant desensitization treatment protocol included daily tacrolimus and mycophe
