For a fixed analytic function g on the unit disc, we consider the analytic paraproducts induced by g, which are formally defined by Tgf(z)=∫0zf(ζ)g′(ζ)dζ, Sgf(z)=∫0zf′(ζ)g(ζ)dζ, and Mgf(z)=g(z)f(z). We are concerned with the study of the boundedness of operators in the algebra Ag generated by the above operators acting on Hardy, or standard weighted Bergman spaces on the disc. The general question

Purpose: To investigate changes in levetiracetam (LEV) serum concentration/dose ratio (C/D-ratio) in relation to pregnancy. Methods: Altogether 21 consecutive pregnancies in 20 women with epilepsy receiving LEV during gestation were studied retrospectively. The main target variable was the C/D-ratio before and during pregnancy, and in the post partum period. Secondary target variables were changes

Aims Short-term ambulatory electrocardiogram (ECG) monitoring is often used to assess premature atrial complex (PAC) and premature ventricular complex (PVC) frequency, but the diagnostic reliability is unknown. The objective of this study was to study the day-to-day variability of PAC and PVC frequency. Methods We used 14-day full-disclosure mobile cardiac telemetry recordings without atrial fibri

Layered materials have attracted significant attention in recent years due to the diverse electronic properties arising from different structural variations. Here, we present angle-resolved photoemission spectroscopy measurements conducted on the topological material Sb4Te3. This material consists of a composite stacking of two distinct topological materials: the three-dimensional (3D) topological

Technological advancements into the nanoscale have made it necessary to perform solid mechanical calculations on devices being produced on this scale. Traditionally, the field of continuum mechanics has been used to perform calculations in the field of solid mechanics, but the ubiquity of faster computers have opened up the field of peridynamics as an alternative. Peridynamic theory models materia

I den här studien utforskas hur makt uttrycks genom språket i den Sydkoreanska filmen Parasit. Likt andra populärkulturella fenomen producerar och reproducerar Parasit en bild av ett samhälle. I samband med det speglas interaktioner mellan individer och uttryck för hur deras relationer skapas. För att få en god förståelse för språkanvändningen i filmen Parasit görs en kvalitativ innehållsanalys av

Osteoarthritis is the most common form of arthritis and is expected to become even more prevalent worldwide with an increasingly older and more obese population. The degenerative joint disease, causing pain, swelling and stiffness in the joints, has a complex etiology and knowledge of the pathophysiological mechanisms is still limited. Recent studies have however reported that the meniscus plays a

The goal of the thesis is to create a method that can be used to smooth data functions so that they are more easily readable and interpretable, through curve fitting. So as to do that, we adapt the smoothing spline method, which uses discrete data, to continuous data.

Med hjälp av netnografisk metod undersöker jag fenomenet tematiska köp-och säljgrupper på Facebook. Tematiska köp-och säljgrupper kan förklaras som nätverk bestående av medlemmar som dels köper, byter och säljer varor med varandra och dels interagerar kring ett gemensamt intresse för vissa varor och märken. Studien tar avstamp i den svenska köp-och säljgruppen Labels we love (svenskt/danskt/snyggt

Biological control is a form of agricultural practice, where a pest’s natural predators are introduced or favored in the agricultural landscape to increase predation on the pests. This increase in predation is beneficial for production but can also drive co-evolutionary adaptation and even diversification within the pest communities which, in turn, may lead to predator responses and diversificatio

The effects of global warming are apparent and the work towards a sustainable future is underway. In order to reduce the environmental impact caused by the transportation sector, a transition from fossil fuels to those based on renewable resources are important. Using agricultural land to produce raw materials, e.g. wheat or corn, for biofuel is controversial as it competes with food production. F

Investments are essential to any economy. Therefore, governments aim to increase the level of total investments done within a country. Investments improve the economy and the productivity of the country. For this reason, it is important to understand which factors can influence investments on a national scale. The primary aim of this study is to investigate factors that could reasonably be exp

Today we depend on data based services, for example in logistics, at warehouses, and accounting services. When a data based service is delayed it can depend on its servers being overloaded, leading to economic losses. To prevent this, it is necessary to have appropriate monitoring tools that can make the system administrators aware of when performance thresholds have been breached and servers are

The goal and ambition of this thesis has been to investigate a topic that could lead to a possible solution to the environmental crisis we are witnesses of. Replacement of fossil fuels is an essential step towards a renewable society that needs to be taken. This thesis will investigate one of those possible solutions, production of a biofuel from a renewable source. A large amount of research with

Attosecond pulses obtained via high harmonic generation often suffer from chromatic aberration. This is inherent from the generation process as a consequence of the spatial profile of the driving laser pulses. Consequently, the focus positions and divergences of consecutive harmonics vary, leading to chromatic aberration which prevents high-quality refocusing as is critically required for applicat
