Accurate density matrix simulation of nuclear spin systems is critical for quantifying magnetic resonance spectroscopy (MRS) data, as well as for simulation studies designed to optimize acquisition parameters. Although a variety of packages exist to achieve this result, no currently available software is capable of computing a large number of spatial points in a reasonable time frame. Here we pres

The rapid development of wearable biomedical systems now enables real-time monitoring of electroencephalography (EEG) signals. Acquisition of these signals relies on electrodes. These systems must meet the design challenge of selecting an optimal set of electrodes that balances performance and usability constraints. The search for the optimal subset of electrodes from a larger set is a problem wit

Syftet med uppsatsen är att ta reda på vilka betydelsefulla ”triggers” som leder till internationell expansion, samt vilka viktiga faktorer som påverkar företagets internationaliseringsprocess. Sex snabbväxande svenska företag intervjuas. Ingen slutsats har kunnat ges generellt för alla företag, men vi har haft tillräckligt med underlag för att få en bra förståelse för vilka som är de vanligaste t

Phytase (EC 3.1.3.-) hydrolyzes phytate (IP6) present in cereals and grains to release inorganic phosphate (Pi), thereby making it bioavailable. The most commonly used method to assay phytase, developed nearly a century ago, measures the Pi liberated from IP6. This traditional end point assay is time consuming and well known for its cumbersomeness in addition to requiring extra caution for handlin

In this work, a new copolymer synthesized in our laboratory is used as physically adsorbed coating for capillary electrophoresis (CE). The copolymer is composed of ethylpyrrolidine methacrylate (EPyM) and methylmethacrylate (MMA). The capillary coating is easily obtained by simply flushing into the tubing an EPyM/MMA solution. It is demonstrated that the composition of the EPyM/MMA copolymer toget

Bridge splitting in chloroform of the orthometalated chloro-bridged complex [Pt(mu-Cl)(2-Me2NCH2C6H4)](2) (1), with ethene, cyclooctene, allyl alcohol and phosphine according to 1 + 2L --> 2 [PtCl(2-Me2NCH2C6H4)(L)], where L = C2H4 (3a), C8H14, (3b), CH2CHCH2OH (3c), and PPh3 (4a and 4b) gives monomeric species with L coordinated trans or cis to aryl. With olefins the thermodynamically stable isom

Grouping of genes into clusters according to their expression levels is important for deriving biological information, e.g., on gene functions based on microarray and other related analyses. The paper introduces the selection of the number of clusters based on the minimum description length (MDL) principle for the selection of the number of clusters in gene expression data. The main feature of the

Syfte: Syftet med uppsatsen är att undersöka om en signifikant skillnad i riskaversion råder mellan de två populationerna, där den ena arbetar för en fast lön och den andra för en provisionsbaserad lön. Även de oberoende variablerna som antas ligga till grund för en individs riskaversion kommer att undersökas. Metod: En tvärsnittsstudie genomfördes av två populationer med hjälp av en internetbasePurpose: The purpose of this thesis is to investigate whether there is a significant difference in risk aversion between the two populations, where one is working for a fixed salary, and the other for a commission-based salary. Independent variables that may represent the individual's risk aversion will also be examined. Methodology: A cross-sectional study of two populations was carried out

Collaborative robots have been designed to perform tasks where human cooperation may occur. Additionally, undesired collisions can happen in the robot’s environment. A contact classifier may be needed if robot trajectory recalculation is to be activated depending on the source of robot–environment contact. For this reason, we have evaluated a fast contact detection and classification method and we

This thesis discusses the provisions of the Rotterdam Rules on electronic transport records. Among the issues addressed are the current law on bills of lading and attempts at establishing systems issuing electronic bills of lading. The theses then goes on to discuss and analyse the provisions on electronic transport records in detail, their history and objective, along with related provisions on t

Background – Advancing the development of highly efficacious and long-lasting malaria vaccines is hampered by incomplete knowledge of protective immune mechanisms and an absence of established correlates of immunity. Antibody avidity is frequently evaluated as an indicator of a high-quality or protective antibody response to vaccination. However, the importance of avidity in vaccine-induced immuni

Streptococcus pyogenes is an exclusively human pathogen that can provoke mild skin and throat infections but can also cause fatal septicemia. This gram-positive bacterium has developed several strategies to evade the human immune system, enabling S. pyogenes to survive in the host. These strategies include recruiting several human plasma proteins, such as the complement inhibitor, C4b-binding prot
