For rotating Bose-Einstein condensates, the occurrence of vortices has been much discussed in the Gross-Pitaevskii approach. Here, we study vortex formation in finite systems with few particles for weak and repulsive two-body interactions, by numerical diagonalization. Vortex formation is surprisingly similar for both (spinless) bosonic and fermionic particles. Breaking the rotational invariance o

The hematopoietic stem cell (HSC) is the prototype organ-regenerating stem cell (SC), and by far the most studied type of SC in the body. Currently, HSC-based therapy is the only routinely used SC therapy; however, advances in the field of embryonic SCs and induced pluripotent SCs may change this situation. Interest into in vitro generation of HSCs, including signals for HSC expansion and differen

Pressure overload activates cardiac fibroblasts leading to excessive production of extracellular matrix which may contribute to compromised heart function. The activated fibroblast acquires smooth muscle-like features such as expression of smooth muscle alpha-actin (SMA) and SM22 and is therefore referred to as myofibroblast. The molecular mechanisms underlying mechanical stress-induced myofibrobl

This thesis argues that general subordinators, such as the Germanic THAT and IF, denote propositional modality. Propositional modality stands for the “speaker’s attitude to the truth-value or factual status of the proposition” (Palmer 2001:24) and is otherwise expressed by moods such as the indicative-subjunctive and epistemic-evidential modal markers. One obvious connection between markers of pro

The clinical knowledge of factors related to the spread of pain on the body has increased and understanding these factors is essential for effective pain treatment. This population-based study examines local (LP), regional (RP), and widespread pain (WSP) on the body regarding comorbidities, pain aspects, and impact of pain and elucidates how the spread of pain varies over time.

Popular Abstract in Swedish Avhandlingen består av fem stycken artiklar som analyserar och estimerar finansiella prisprocesser. Alla artiklarna handlar också om stokastiska volatilitetsprocesser som estimeras med Bayesiansk statistik och Markov Chain Monte Carlo (MCMC) metoder. Det första pappret utvecklar en modell för att mäta den amerikanska och de regionala europeiska aktiemarknadernas påverkThis dissertation consists of five papers concerned with the estimation and analysis of financial price processes. The first paper develops a stock price model and analyzes the impact of the US and the regional European stock markets on the local European countries’ stock markets. Among several things, we find that the dependencies among the stock markets do not increase during periods of distress

The atomic distances in hexagonal polytypes of III-V compound semiconductors differ from the values expected from simply a change of the stacking sequence of (111) lattice planes. While these changes were difficult to quantify so far, we accurately determine the lattice parameters of zinc blende, wurtzite, and 4H polytypes for InAs and InSb nanowires, using X-ray diffraction and transmission elect

Research has shown that families experience poor involvement in needs assessment of older people while little is known about municipal care managers' views of family participation. The aim was to explore how municipal care managers view families' participation in and influence on needs assessment of older people receiving public home help. Individual interviews (n = 26) were conducted with care ma

Optical computing has been pursued for decades as a potential strategy for advancing beyond the fundamental performance limitations of semiconductor-based electronic devices, but feasible on-chip integrated logic units and cascade devices have not been reported. Here we demonstrate that a plasmonic binary NOR gate, a 'universal logic gate', can be realized through cascaded OR and NOT gates in four

This document describes the package CHIRON which includes two libraries, chironitself and jbnumlib. chiron is a set of routines useful for two-loop numerical results in chiral perturbation theory (ChPT). It includes programs for the needed one-and two-loop integrals as well as routines to deal with the ChPT parameters. The present version includes everything needed for the masses, decay constants

The consequences of climate change for bird populations have received much attention in recent decades, especially amongst cavity-nesting songbirds, yet little has been written on ducks (Anatidae) despite these being major elements of wetland diversity and important quarry species. This paper reviews the major known consequences of climate change for birds in general, and relates these to the limi

Detection, immobilization and purification of carbohydrates can be done using molecular probes that specifically bind to targeted carbohydrate epitopes. Carbohydrate binding modules (CBMs) are discrete parts of carbohydrate hydrolyzing enzymes that can be engineered to bind and detect specifically a number of carbohydrates. Design and engineering of CBMs has benefited greatly from structural studi

This thesis explores contemporary modes of video activism for a radical politics of the Left. It offers an analytical contribution to media and communication that promotes an understanding of radical online video as modes of political engagement in contemporary online environments. By focusing on YouTube as one of the most prevalent spaces in which radical video is screened and experienced today,

Biomarker identification is of utmost importance for the development of novel diagnostics and therapeutics. Here we make use of a translational database selection strategy, utilizing data from the Human Protein Atlas (HPA) on differentially expressed protein patterns in healthy and breast cancer tissues as a means to filter out potential biomarkers for underlying genetic causatives of the disease.

Weak separability is an important concept in many fields of economic theory. This chapter uses Monte Carlo experiments to investigate the performance of newly developed nonparametric revealed preference tests for weak separability. A main finding is that the bias of the sequentially implemented test for weak separability proposed by Fleissig and Whitney (2003) is low. The theoretically unbiased Sw

In this letter we report on high-frequency measurements on vertically standing III-V nanowire wrap-gate MOSFETs (metal-oxide-semiconductor field-effect transistors). The nanowire transistors are fabricated from InAs nanowires that are epitaxially grown on a semi-insulating InP substrate. All three terminals of the MOSFETs are defined by wrap around contacts. This makes it possible to perform high-
