With the rapid growth of mobile communication systems, massive multiple-input multiple-output (MIMO) technology plays a key role in enhancing communication systems to meet growing data traffic demands. However, scaling the technology further challenges the system designers to balance design tradeoffs in order to provide efficient and low-cost communication systems. This requires efficient hardware
The biogeophysical forcing resulting from the change in land-surface properties (such as albedo) is of particular interest as it can increase, decrease, or offset the biogeochemical forcing resulting from the changes in atmospheric greenhouse gas concentrations due to deforestation, forest management, or reforestation/afforestation (i.e., land-use/land-cover change, LULCC). Moreover, the biogeophy
Purpose: We aimed to investigate the incidence and clinical features of Streptococcus dysgalactiae peripartum infections (SDPI), and to investigate the distribution of emm-types in relation to disease severity and the genetic relatedness of isolates from hospital clusters. Materials and methods: Patients with growth of S. dysgalactiae in a genital or wound culture, collected between January 2014 a
BACKGROUND: Both hospitalised (H) and non-hospitalised (NH) individuals may have different symptoms and impairments after COVID-19. We aimed to explore symptoms, mental and physical health after initial COVID-19 for both groups of individuals and the association between physical and mental impairments in relation to self-rated health status and to identify different cluster profiles.METHODS: Parti
Background: Despite recommendations by EU, surveillance of Lyme neuroborreliosis (LNB) is still not fully implemented in all member states, Sweden being one of them. Laboratory-based notifications on positive Borrelia antibody index (AI) in paired cerebrospinal fluid-serum samples alone have been suggested for surveillance of LNB. Objectives: We aim to describe the epidemiology of Lyme borreliosis
Early vision is the process occurring before any semantic interpretation of an image takes place. Motion estimation, object segmentation and detection are all parts of early vision, but recognition is not. Some models in early vision are easy to perform inference with---they are tractable. Others describe the reality well---they have high fidelity. This thesis improves the tractability-fidelity tr
Popular Abstract in Swedish Deponier (soptippar) har förändrats kraftigt de senaste decennierna. Detta beror främst på ändrad lagstiftning vilken i sin tur till stor del bygger på en önskan att skydda miljön. Dock har lag¬stiftningen implementerats utan riktig kännedom om dess konsekvenser för utsläppen från deponier på lång sikt. För att öka förståelsen för konsekvenserna genomfördes det forskninWaste management in Europe has changed, mainly as a result of stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. The biogeochemistry of landfills has changed due to their reduced organic content. The research pres
Summertime measurements of CO2 and CH4 fluxes were carried out over a range of high-arctic ecosystem types in the valley Zackenbergdalen since 1996 using both chamber and eddy covariance methodology. The net ecosystem CO2 exchange and CH4 flux data presented reveal a high degree of inter-annual variability within the dominant vegetation types in the valley, but also show distinct differences betwe
Background. Fast and accurate work-up is crucial to ensure the best possible treatment and prognosis for patients with head and neck cancer. The presence or absence of neck lymph node metastases is important for the prognosis and the choice of treatment. Clinical lymph node (N)-staging is done by palpation and diagnostic imaging of the neck. We investigated the current practice of the initial radi
All notified MRSA cases in SkAyenne County have been followed since 2000. We have investigated the MRSA epidemiology over time, method of acquisition, whether some spa types are more prone to spread, and/or cause more infections, and the connection between spa type and country of acquisition/origin. All cases between 2000 and 2010 were included. Infection or colonization and the presence of PVL ge
This paper reviews the evidence for an association between atypical subtrochanteric fractures and long-term bisphosphonate use. Clinical case reports/reviews and case-control studies report this association, but retrospective phase III trial analyses show no increased risk. Bisphosphonate use may be associated with atypical subtrochanteric fractures, but the case is yet unproven. A Working Group o
Background-The number of circulating blood monocytes impacts atherosclerotic lesion size, and in mouse models, elevated levels of high-density lipoprotein cholesterol suppress blood monocyte counts and atherosclerosis. We hypothesized that individuals with mild renal dysfunction at increased cardiovascular risk would have reduced high-density lipoprotein levels, high blood monocyte counts, and acc
In the study reported here we examined the short-term effects (1-3 years) of slash retention (SR) and the long-term effects (13-15 years) of wood-ash application (A) on fine roots and mycorrhizae in a 40-year-old Norway spruce forest in southwest Sweden. Soil cores were used to obtain estimates of the biomass (g m(-2)) of roots in three diameter classes (< 0.5, 0.5-1 and 1-2 mm), root length densi
The growing proportion of green energy in the electricity grids brings with it a growing need of grid stabilizing resources to counteract the inherent intermittency of renewable energy resources. This is where the grid scale energy storages come in handy. They efficiently offset the intermittencies of solar, wind etc. resources by energy arbitrage and peak shifting. This thesis looks into the econ
Quality Indicators: Help or hinder? - The study examines the National Board of Health and Welfare's construction of quality in women's shelters in relation to women's safety and security. The study is based on the quality indicators developed by the National Board of Health and Welfare on behalf of the government. The National Board of Health and Welfare is an authority in Sweden with
The purpose of this master’s thesis is to gain in-depth knowledge about how the provision of digital books via the e-book service Biblio functions in Swedish public libraries and how this activity can be understood through the library's mission of promoting the development of a democratic society. To gather the empirical material for this study, we have conducted semi-structured interviews wit

Autoimmune diseases are complex and characterized by the loss of self-tolerance to self-antigens, leading to an immune attack on target tissues of the body. Psoriasis (Ps) and psoriasis arthritis (PsA) are poorly understood autoimmune diseases with unknown genetic and environmental sources. It has been previously demonstrated that a single intra peritoneal injection of mannan induces an acute infl
Agriculture is an essential economic activity which sustains the livelihood of millions of people around the world. Maize is one of the most grown, consumed and traded cereals in the world mostly because of its adaptability to varied environmental conditions. Maize farming depends on climatic factors like temperature, rainfall and radiation to thrive but this also means that it is very susceptible
Dams are pervasive features of the river systems in the United States. More than 80,000 large dams, and as many as 2.5 million small dams, are spread throughout every major watershed in the country. While this vast number of dams has made a considerable contribution to development, recognition of the environmental impacts has significantly increased. Furthermore, over 25% of the nation's dams
