Modelling and Forecasting Short-Term Interest Rate Volatility: A Semiparametric Approach

This paper employs a semiparametric procedure to estimate the diffusion process of short-term interest rates. The Monte Carlo study shows that the semiparametric approach produces more accurate volatility estimates than models that accommodate asymmetry, levels e¤ect and serial dependence in the conditional variance. Moreover, the semiparametric approach yields robust volatility estimates even if

Dating Components of Human Atherosclerotic Plaques

Rationale: Atherosclerotic plaques that give rise to acute clinical symptoms are typically characterized by degradation of the connective tissue and plaque rupture. Experimental studies have shown that mechanisms to repair vulnerable lesions exist, but the rate of remodeling of human plaque tissue has not been studied. Objective: In the present study, we determined the biological age of different

Writing in Deconstruction vs Speech in Structuralism (Jacques Derrida vs Ferdinand de Saussure)

Speech is already in itself a writing. Any concept that is to name, to stay for the abstract or concrete reality is made up of a mental trace. There is always a sleepy-waiting yet ever present trace at the origin of the representation and the naming of any ontological phenomenon. The trace is itself The apriori ontology – and this is how writing is pre-eminent to the later formal verbalization of

Comparison of Gen-Probe Transcription-Mediated Amplification, Abbott PCR, and Roche PCR Assays for Detection of Wild-Type and Mutant Plasmid Strains of Chlamydia trachomatis in Sweden

The clinical performance of two nucleic acid amplification assays targeting the cryptic plasmid and two assays targeting rRNA molecules in Chlamydia trachomatis was examined. First-catch urine samples from Malmoe, Sweden, were tested for C. trachomatis with the Abbott real-time PCR assay m2000 and an in-house PCR for the new variant strain of C. trachomatis with a deletion in the cryptic plasmid.

'An entirely different culture and an alien race' : Scandinavian Ukrainian encounters on the Canadian prairies, 1910-1940

While contacts between Scandinavia and Kievan Rus’ in recent history have been limited, and Scandinavian, and Scandinavian-Canadian attitudes to Ukrainians were long characterized by an aggressive hostility and racist stereotypes. The image of the “Galician” merged with stereotypes of Russians, which have a long tradition in Scandinavia and Germany. “Galicians” became synonymous with backwardness,

Iterative receivers with channel estimation for MIMO and multi-user OFDM systems

Popular Abstract in Swedish Idag tar de flesta för givet att man när och var som helst kan komma åt sin e-post, ladda upp bilder till Facebook eller söka kunskap på Wikipedia från sin mobiltelefon eller dator. Den trådlösa teknologi som gjort detta möjligt har utvecklats oerhört det senaste årtiondet, men behöver utvecklas ännu mer för att möta det ökande behovet av trådlös kommunikation. I dennaThe traffic in wireless networks has been showing an exponential growth over the last decade. In order to meet the demand, and support a continuation of this growth, the scarce radio resources need to be efficiently used. The use of multiple antenna (MIMO) systems and iterative (turbo) receivers has significantly improved the realizable system performance. Still, many challenges exist in the devel

Styra med mål - en process utan slut?

I Lomma kommun gör man det, Universitetssjukhuset Mas (UMAS) likaså. Även Hässleholms sjukhusorganisation (Hässleholms sjukhus) gör det. Styr med mål. Det kan vi konstatera efter att precis ha avslutat en rapport som handlar om att framgångsrikt styra med mål. Rapporten har Föreningen Sveriges Kommunalekonomer finansierat. För er som vill läsa hela rapporten finns den att hämta på www.kef.se. Rapp

Alternative Lead Systems for Diagnostic Electrocardiography: Validation and Clinical Applicability

Popular Abstract in Swedish Standard-12-avlednings-EKG är fortfarande ett av de viktigaste och vanligaste redskapen för att diagnostisera hjärtsjukdom trots att ett flertal olika undersökningstekniker har utvecklats under åren. Vid standard-EKG används 10 elektroder, 6 på bröstkorgen och 4 distalt på armar och ben. Inom både industrin och akademin har många års arbete lagts ned på utveckling av deThe standard 12-lead electrocardiogram (ECG) remains one of the most important and most frequently used tools for diagnosing cardiac diseases, although several different examination modalities in cardio¬logy have been developed over the years. The standard ECG uses 10 electrodes placed on well-defined positions on the body, 6 on the torso and 4 distally on the limbs. Both industry and academia hav

Element analysis of the eutardigrades Richtersius coronifer and Milnesium cf. asiaticum using particle induced X-ray emission (PIXE)

Semi-terrestrial tardigrades are well-known for their tolerance to a variety of environmental extremes, including desiccation, freezing and radiation. Despite several attempts to reveal the genetic and molecular mechanisms behind the resilience of tardigrades, it is still unknown how these animals are able to maintain the integrity of their cellular components under severe stress. Quantitative or

On Feminist Activist Aesthetics

This article discusses some trends in critical theory and activist aesthetics in contemporary feminist performing arts in Sweden. The 2000s have witnessed at least two “turns” in feminist theory, namely the affective turn and the social, or as it is called here, the solidarity turn. The status of poststructuralist theory has been widely debated and Marxist, class-based analyses have returned to th

Private eco-brands and green market development: towards new forms of sustainable governance in food retailing

This study seeks to analyze the role of retail eco-brands in the development of markets for sustainability certified food products. Building on insights from the New Institutional Economics (NIE) paradigm, but also broader literature in the supply chain management and marketing research, we suggest that private eco-branding and third-party certification can be explained as private institutional ar

Long-term simulations of subaerial beach erosion and overwash during storms

During severe storms, high waves and water levels can reach the subaerial portion of the beach and cause significant morphological change at elevations where the waves cannot reach under typical sea conditions. Coastal dunes may suffer direct wave impact and erode, increasing the likelihood of overwash and breaching, potentially flooding low-lying areas behind the dunes. Barrier islands are also v

Influence of the minimum chip thickness on the obtained surface roughness during turning operations

Considerable efforts have been put into analyzing the obtained surface roughness during turning operations. However, knowledge is still lacking on how to model the arithmetic mean surface roughness Ra through using a general model applicable for all workpiece materials and process parameters. Further, the influence of the minimum chip thickness on the obtained surface roughness needs to be clarifi

A Comparative Analysis of the Mechanism of Toll-Like Receptor-Disruption by TIR-Containing Protein C from Uropathogenic Escherichia coli.

The TIR-containing protein C (TcpC) of uropathogenic Escherichia coli strains is a powerful virulence factor by impairing the signaling cascade of Toll-like receptors (TLRs). Several other bacterial pathogens like Salmonella, Yersinia, Staphylococcus aureus but also non-pathogens express similar proteins. We discuss here the pathogenic potential of TcpC and its interaction with TLRs and TLR-adapte

Effects of season, water and predation risk on patch use by birds on the African savannah

Birds from semi-arid regions may suffer dehydration during hot, dry seasons with low food availability. During this period, both energetic costs and water requirements for thermoregulation increase, limiting the scope of activity. For granivorous birds feeding on dry seeds, this is a major challenge and availability of water may affect the value of food. Water availability could (1) increase the v

On Hardware Implementation of Discrete-Time Cellular Neural Networks

Cellular Neural Networks are characterized by simplicity of operation. The network consists of a large number of nonlinear processing units; called cells; that are equally spread in the space. Each cell has a simple function (sequence of multiply-add followed by a single discrimination) that takes an element of a topographic map and then interacts with all cells within a specified sphere of intere
