Massive multiple input multiple output (MIMO) is a revolutionary communication technique, where large numbers of antennas are employed at the base stations to increase the spectral efficiency, reliability and data rate of the system. Moreover, in multi-user MIMO (MU-MIMO) multiple users can be served by the base stations on the same time-frequency resource. Distributed antenna system (DAS) is a fo

Mass spectrometry confirmed that the entire denitrification system of Thiosphaera pantotropha is present under aerobic conditions. Acetate-dependent oxygen uptake is totally inhibited by 0.3mM cyanide. Nitrate reduction by cells grown with and without nitrate was inhibited by 10 and 15mM azide, respectively. The nitrous oxide reductase was totally inhibited by 1% acetylene or 0.125mM cyanide. This

A general, unstructured mathematical model has been used to describe the behaviour of nutrient-limited growth of two bacteria in a continuous co-culture. The experimental system consisted of a two-membered mixed culture of the heterotrophic nitrifier/aerobic denitrifier, Thiosphaera pantotropha, and the autotrophic nitrifier, Nitrosomonas europaea, competing for ammonia in chemostat culture. The o

This work treats multi-pitch estimation, and in particular the common misclassification issue wherein the pitch at half of the true fundamental frequency, here referred to as a sub-octave, is chosen instead of the true pitch. Extending on current methods which use an extension of the Group LASSO for pitch estimation, this work introduces an adaptive total variation penalty, which both enforce grou

Jag avser att redogöra för sambandet, eller förhållandet, mellan formlerna 1+1=♥ och (∀a) (Ǝb) (∀c) [[(cϵa) u λ (c)] → (cϵ b)]. Då den förra formeln är hämtad från ett internetforum för personer diagnostiserade med adhd och deras anhöriga, så är den senare hämtad från den franske filosofen Alain Badious (2005a) mängdteori vari han närmar sig en ontologi om varat. Mitt eget avhandlingsprojekt rör d

Lesions of ERBB2, PTEN, and PIK3CA activate the phosphatidylinositol 3-kinase (PI3K) pathway during cancer development by increasing levels of phosphatidylinositol-3,4,5-triphosphate (PIP(3)). 3-Phosphoinositide-dependent kinase 1 (PDK1) is the first node of the PI3K signal output and is required for activation of AKT. PIP(3) recruits PDK1 and AKT to the cell membrane through interactions with the

Identification and relative quantification of hundreds to thousands of proteins within complex biological samples have become realistic with the emergence of stable isotope labeling in combination with high throughput mass spectrometry. However, all current chemical approaches target a single amino acid functionality (most often lysine or cysteine) despite the fact that addressing two or more amin

This dissertation examines the changing time allocation of men and women at the turn of the 21st century in Sweden, an interesting case given its strong position concerning female labor force participation, maternal employment, and gender equality. The aim is to examine to what extent gender and parenthood affect various types of time allocation, both in the labor market and household, and provide

Aim: To investigate patterns of somatic inpatient ICD-10 diagnoses in people with intellectual disabilities (ID) 55 years and older in relation to age over an 11-year period, and to compare these patterns with a general population sample. Method: The study was based on Swedish national registers. The ID group (n=7936) comprised people who were aged 55 or above in 2012. They were age- and sexmatche

Aim: Life expectancy of people with intellectual disability (ID) has increased along with that in the general population. The aims were to estimate prevalence of older people with intellectual disabilities (ID) during 2004-2012, and identify differences in prevalence across counties in Sweden. Method: Individuals aged 55+ years were identified through two national registers; the LSS register and t

Background: Tyrosine kinase inhibitors (TKIs) have increased survival dramatically for patients with chronic myeloid leukemia (CML), but continuous administration of these drugs may elicit long-term toxicity. Objective: To investigate the incidence of vascular events in patients with CML treated with first-and second-generation TKIs. Design: Retrospective cohort study using nationwide population-b

BACKGROUND: Long commutes by car are stressful. Most research studying health effects of commuting have summarized cross-sectional data for large regions. This study investigated whether the levels of stress and individual characteristics among 30–60 min car commuters were similar across different places within the county of Scania, Sweden, and if there were changes over time. METHODS: The study p

Distributed averaging is one of the simplest and most widely studied network dynamics. Its applications range from cooperative inference in sensor networks, to robot formation, to opinion dynamics. A number of fundamental results and examples scattered through the literature are gathered here and some original approaches and generalizations are presented, emphasizing the deep interplay between the

Governments increasingly rely on the use of market instruments to tackle climate change and help decarbonize a deeply fossil fuel-dependent economy. This dissertation examines this trend as one instance of the ‘commodification of carbon’, or the process through which emission reductions are made into commodities and then traded on the market. It engages the commodification framework and related th

Locally induced, magnetic order on the surface of a topological insulator nanowire could enable room-temperature topological quantum devices. Here we report on the realization of selective magnetic control over topological surface states on a single facet of a rectangular Bi2Te3 nanowire via a magnetic insulating Fe3O4 substrate. Low-temperature magnetotransport studies provide evidence for local

This study investigated if mental reinstatement of an encoding context during retrieval increases memory accessibility. Participants performed a cued-recall memory task where the overlap between encoding and retrieval context and the nature of context reinstatement (mental versus physical) were manipulated. Memory performance improved when the encoding-retrieval context overlapped in a comparable
