Popular Abstract in Swedish Avhandlingens bidrag ligger inom området för Markov regimskiftesmodeller i tidsserieanalys. Den består av fem separata uppsatser som specifikt undersöker två statistiska frågeställningar, samt applicerar metodologin på fyra olika makroekonomiska områden. De två huvudsakliga statistiska bidragen rör (i) utvecklandet av ett flexibelt test baserat på simulering för att utrThis dissertation studies statistical properties and applications of the Markov switching models for economic time series in five separate papers. The two main statistical themes are (i) the task of choosing the number of states to use in the model, and (ii) inference on time-varying transition probabilities. Our empirical applications span a wide array of topics in international finance and macro

Natural killer (NK) cells are large granular lymphocytes that are components of the innate immune system. These cells are key players in the defense against viral and other microbial infections and cancer and have an important function during pregnancy, autoimmunity and allergy. Furthermore, NK cells play important roles in hematopoietic stem cell (HSC) transplantation by providing the graft versu

Introduction: Asthma is a complex, heterogeneous and mutifactorial disease and represents a major health problem in Westernised countries. The airway epithelium, with its direct physical contact with luminal triggers, has a major role in determining the nature of inflammation that develops in asthmatic airways. Objective: The present review aims to provide a brief overview of the numerous ways the

BACKGROUND: Rye and wheat bran were treated with several xylanases and endoglucanases, and the effects on physicochemical properties such as solubility, viscosity, water-holding capacity and particle size as well as the chemical composition of the soluble and insoluble fractions of the bran were studied. A large number of enzymes with well-defined activities were used. This enabled a comparison be

Philadelphia (Ph) chromosome-positive leukemia is characterized by the BCR/ABL1 fusion protein that affects a wide range of signal transduction pathways. The knowledge about its downstream target genes is, however, still quite limited. To identify novel BCR/ABL1-regulated genes we used global gene expression profiling of several Ph-positive and Ph-negative cell lines treated with imatinib. Followi

Background There are limited data available on tumour subtype-specific familial risks for nervous-system tumours. We aimed to provide such data at the population level. Methods We used data from the nationwide Swedish and Norwegian databases on familial cancer to calculate standardised incidence ratios (SIRS) for the familial risk of developing a nervous-system tumour in offspring born after 1931

Soot formation in a turbulent jet diffusion flame is modeled using an unsteady flamelet approach in post-process. In the present work, we apply a detailed kinetic soot model with a sectional method, and study the evolution of the particle size distribution. Detailed information on the evolution of the soot particle size distribution function is acquired. It is found that the particle size distribu

Today, the underlying theoretical and methodological foundations as well as implementations in the field of accessibility are largely based on plans, metrics and heuristics. There is an obvious tension between these norms and those of the overall spirit of the times, which leans heavily towards improvisations, diversity, and ever-changing affordances. The parallel evolution of human computer inter

The high number of /-expressing T cells found in the epithelial lining layer suggests that they form a first line of defence against invading pathogens. To evaluate the role of / T cell-receptor (TCR)-expressing cells in cutaneous infection caused by Staphylococcus aureus, mice lacking /-expressing T cells (TCR/) were inoculated intradermally with S. aureus, and compared with S. aureus-infected co

Fiberförstärkta plastkonstruktioners inverkan på risknivå ombord på stora passagerarfartyg Användning av fiberförstärkta plastkonstruktioner (FRP) inom den marina sektorn har blivit alltmer intressant ur ett hållbarhetsperspektiv. Problemet med FRP som byggnadsmaterial är att det är brännbart, vilket på grund av tradition och reglering gör det svårt att övergå från, det mer traditionella materialeThe main objective of this project was to determine how a FRP composite structure performs compared to a steel structure in regard to fire safety and risk level during an evacuation. More specifically the objective was to study how the differences in the thermal properties influence the smoke layer height, visibility and the temperature of the gases in the early stages of a fire. This was done by
