Inte, nog och visst i mittfält och fundament

I denna uppsats behandlas satsadverbialen inte, nog och visst. De undersöks, var för sig, i två positioner i satsen, nämligen fundamentet och den typiska satsadverbials¬positionen (A1). Syftet är att beskriva adverbialens möjliga betydelser i respektive position. Utifrån hur de, i olika talsituationer och kontexter, inverkar på talarens inställning till satsens proposition i fundamentet och i A1,

When more poor means less poverty: On income inequality and purchasing power

We show theoretically that the poor can benefit from price changes induced by higher income inequality. As the number of poor increases, the market for products aimed toward the poor grows, and such products become more profitable. As a result, there are circumstances where an increase in income inequality associates with higher purchasing power of the poor. Using cross-country data on the price o

Weak localization in FeSe1-xTex superconducting thin films

We have investigated the magneto-resistivity (MR) of FeSe1-xTex superconducting films on MgO substrate. The MR of pure FeSe and slightly Te-substituted films demonstrates regular Lorentz-type magnetic field dependence, MR similar to B-2. In highly Te-substituted samples, however, negative MR contribution due to the weak-localization effect gradually dominates at low temperature, which is consisten

Finding Risk Groups by Optimizing Artificial Neural Networks on the Area under the Survival Curve Using Genetic Algorithms

We investigate a new method to place patients into risk groups in censored survival data. Properties such as median survival time, and end survival rate, are implicitly improved by optimizing the area under the survival curve. Artificial neural networks (ANN) are trained to either maximize or minimize this area using a genetic algorithm, and combined into an ensemble to predict one of low, interme

A note on the use of the LLC panel unit root test

One of the single most cited studies within the field of nonstationary panel data analysis is that of LLC (Levin et al. in J Econom 98:1-24, 2002), in which the authors propose a test for a common unit root in the panel. Using both theoretical arguments and simulation evidence, we show that this test can be misleading unless it is based on the same bandwidth selection rule used by LLC.

Lifestyle Risk Factors for Ischemic Stroke and Transient Ischemic Attack in Young Adults in the Stroke in Young Fabry Patients Study

Background and Purpose-Although many stroke patients are young or middle-aged, risk factor profiles in these age groups are poorly understood. Methods-The Stroke in Young Fabry Patients (sifap1) study prospectively recruited a large multinational European cohort of patients with cerebrovascular events aged 18 to 55 years to establish their prevalence of Fabry disease. In a secondary analysis of pa

Uptake of pulse injected nitrogen by soil microbes and mycorrhizal and non-mycorrhizal plants in a species-diverse subarctic heath ecosystem

N-15 labeled ammonium, glycine or glutamic acid was injected into subarctic heath soil in situ, with the purpose of investigating how the nitrogen added in these pulses was subsequently utilized and cycled in the ecosystem. We analyzed the acquisition of N-15 label in mycorrhizal and non-mycorrhizal plants and in soil microorganisms, in order to reveal probable differences in acquisition patterns

Chronic Total Occlusions in Sweden - A Report from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR)

Introduction: Evidence for the current guidelines for the treatment of patients with chronic total occlusions (CTO) in coronary arteries is limited. In this study we identified all CTO patients registered in the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) and studied the prevalence, patient characteristics and treatment decisions for CTO in Sweden. Methods and Results: Between Ja

Calcium-induced mitochondrial permeability transition in CNS-derived mitochondria - Pharmacological aspects of specificity and toxicity in neuroprotection

Mitochondria are the main site for energy conversion in the cell. Under certain circumstances, such as excess calcium retention or production of reactive oxygen species, a pore forms at contact sites between the outer and the normally impermeable inner mitochondrial membrane. The ensuing osmotic mitochondrial swelling and loss of bioenergetic function is referred to as the mitochondrial permeabili

Band Structure Effects on the Scaling Properties of [111] InAs Nanowire MOSFETs

We have investigated the scaling properties of [111] InAs nanowire MOSFETs in the ballistic limit. The nanowire band structure has been calculated with an Sp(3)d(5)s* tight-binding model for nanowire diameters between 2 and 25 nm. Both the effective band gap and the effective masses increase with confinement. Using the atomistic dispersion relations, the ballistic currents and corresponding capaci

Change in prostate volume during extreme hypo-fractionation analysed with MRI.

Hypo-fractionated external beam radiotherapy with narrow CTV-PTV margins is increasingly applied for prostate cancer. This demands a precise target definition and knowledge on target location and extension during treatment. It is unclear how increase in fraction size affects changes in prostate volume during treatment. Our aim was to study prostate volume changes during extreme hypo-fractionation

Morphology-Function Relationships and Repeatability in the Sperm of Passer Sparrows

Sperm performance is likely to be an important determinant of male reproductive success, especially when females copulate with multiple males. Understanding sperm performance is therefore crucial to fully understand the evolution of male reproductive strategies. In this study, we examined the repeatability of sperm morphology and motility measures over three breeding seasons, and we studied relati
