This article investigates digital predistortion (DPD) linearization of hybrid beamforming large-scale antenna transmitters. We propose a novel DPD processing and learning technique for an antenna sub-array, which utilizes a combined signal of the individual power amplifier (PA) outputs in conjunction with a decorrelation-based learning rule. In effect, the proposed approach results in minimizing t
The main concern of this book is to determine when the gap in living standards between the East and the West emerged. Why did Europe experience industrialization and modern economic growth before China, India, or Japan? This is one of the most fundamental questions in Economic history and one that has provoked intense debate. The established view, dating back to Adam Smith, is that the gap emerged
Urban Squares suggests a specific and fresh take on agorology – the study of urban squares. The approach is one of recording everyday life and focusing on different ways to describe and investigate the public life and space of urban squares. The book comprises four empirical case studies of squares focusing especially on the urban material culture and spatio-temporal changes of these squares. The
Popular Abstract in Swedish Intresset för biobränsle som en alternativ energiresurs har ökat eftersom utsläppen av CO2, NOx och SO2 bör sänkas. Användningen av biobränsle i en trycksatt fluidiserad bädd förbrännare/förgasare är därför en teknik som är lovande. En fluidiserad bädd har en rad fördelar såsom effektiv värmeöverföring, bränsleflexibilitet och låg förbränningstemperatur. Trots sina fördIncreasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. However, this is not a problem-free technique, since the flue gas can contain ammonia, NOx and tar. The fluidised bed can
This book explores the historical, biblical, christological, trinitarian, and ecclesiological dimensions of soteriology in Jewish-Christian relations.
B cell homeostasis is regulated by multiple signaling processes, including nuclear factor-kappaB (NF-kappaB), BAFF-, and B cell receptor signaling. Conditional disruption of genes involved in these pathways has shed light on the mechanisms governing signaling from the cell surface to the nucleus. We describe a novel mouse strain that expresses solely and excessively a naturally occurring splice va
This thesis investigates the relationship between eye movements, mental imagery and memory retrieval in four studies based on eye-tracking experiments. The first study is an investigation of eye movements during mental imagery elicited both visually and verbally. The use of complex stimuli and the development of a novel method where eye movements are recorded concurrently with verbal data enabled
Objective: The etiology of abdominal aortic aneurysm (AAA) includes atherosclerotic, inflammatory, immunological and coagulatory mechanisms. The aim of this study was to evaluate associations between markers for some of these mechanisms and AAA-size, in order to identify markers which might later be evaluated in relation to aneurysm growth. Material and methods: Prospectively 360 AAA-patients and
Microcystis blooms are implicated in toxic algal blooms worldwide due to the production of toxins microcystins. Blooms have caused poisoning of humans and other animals, and annually contribute to economic loss. The biological role of microcystin synthesis by the genus Microcystis remains an unanswered question. Consequently, the factors that select for microcystin producing (toxic) phenotypes ove
The main aim of this thesis is to analyse the climate adaptation strategies regarding water resources in the regional context of the three major riparians of the Euphrates and Tigris rivers: Turkey, Syria and Iraq. The objectives are: to base the analysis on the criteria benefit, consequences and limits to the social as well as the technical factors affecting the water availability and to use WW-H
In this study, a hydrochemical and biological investigation, and a vulnerability assessment were conducted on the Los Bambinos aquifer during the spring of 2020. A literature study on previous studies conducted in the area was also made. This aquifer is located on the southwestern slope of the Barva volcano, northeast of Alajuela, Costa Rica. The hydrochemical investigation found the groundwater t
The broader goal of this project was to investigate what kind of effects the accumulation of polyhydroxyalkanoates (PHA) in the marine environment might have on the microbial world. Bacteria were isolated from biofilms fouling PHA pellets placed in the sediment-water interface; the goal was to isolate PHA degraders that were also sulphate reducers. Eleven strains were isolated and for three of the
Urban inequalities are one of the most important questions in contemporary times. One urban area that is struggling with inequalities is Malmö, the third largest city in Sweden. The new comprehensive plan for Malmö from 2018, states that a socially balanced city is necessary for further development of Malmö, to tackle inequalities the plan states that all citizens need to be able to shape society
This pre- and post-measure interventional study attempted to create a positive attitude shift in environmental attitudes of 80 students using the choice blindness (CB) manipulation. It is a novel approach that first manipulates the participants’ answers and secondly asks the subjects to justify the answer they did not choose, to elicit attitude change. The second condition utilised a persuasive te
Stora magmatiska provinser återfinns långt tillbaka i jordens geologiska historia, från Arkeikum till Kenozoikum, och kan ha en stor påverkan på det globala klimatet. Den hög-arktiska stora magmatiska provinsen (HALIP) bildades under tidig Krita och rester av denna storskaliga magmatism kan observeras i hela Arktis. Relativt få U-Pb åldrar har än så länge blivit analyserade och mer geokronologisk Large Igneous Provinces are widespread in the geological record, from the Archean to the Cenozoic, and can have a significant impact on the global climate. The High Arctic Large Igneous Province (HALIP) was emplaced during the Early Cretaceous, and remnants of this large-scale magmatism can be found all over the circum-Arctic. Relatively few high-precision U-Pb ages have been analyzed to date, and
Wearing Hanfu(汉服) is an emerging phenomenon in urban landscapes in Mainland China. On the other hand, Hanfu is a relatively obscure focus of study in academia. Born in the social context of nostalgia and traditional learning, Hanfu has grown into a clothing culture popular among the younger generations. By asking the question, how young people in the Hanfu cultural community perceive and express t
This paper empirically explores 10 years of play-by-play data from the seasons 2011-2021 from National Basketball Association with a comprehensive dataset with 2.7 million shots to test for a hot hand, (i.e., predictability in future outcomes) using three separate models. I find proof for its existence in all short-term categories using panel data as well as when adjusting for shot difficulty usin
This thesis examines the intersection between the cultural sector and international development in Mozambique, focusing on the practical implications of the increased attention given to the sector and the depoliticization processes that have emerged. Three research questions are addressed: - What are the practical implications of the increased attention given to the cultural sector by internationa
