Massive MIMO is one of the leading technologies for connecting very large numbers of energy-constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes into groups that can communicate simultaneously such that the mutual interference is minimized. Here we propose node partitioning strategies that do not require full c
We report on the preparation of high performance field-effect transistors (FETs) based on large areas of aligned films of a TTF derivative, namely, tetrakis-(octadecylthio)-tetrathiafulvalene (TTF-4SC18). TTF-4SC18 assembles into one-dimensional stacks in which the long alkyl chains promote intermolecular π-π overlapping due to their extremely closely packed nature. The films were prepared from so
Background: Creativity is a multifaceted, complex, activity, and as such is an overarching function of the brain rather than being confined to a specific structure or region. Alzheimer's disease effects several cognitive domains involved in the creative process of producing art. Objective: We analyze the art of a well-known Swedish visual artist who suffered from Alzheimer's disease to determine i
How do humans construct their mental representations of the passage of time? The universalist account claims that abstract concepts like time are universal across humans. In contrast, the linguistic relativity hypothesis holds that speakers of different languages represent duration differently. The precise impact of language on duration representation is, however, unknown. Here, we show that langu
Providing humoral immunity, antibody-secreting plasma cells and their immediate precursors, the plasmablasts, are generated in systemic and mucosal immune reactions. Despite their key role in maintaining immunity and immunopathology, little is known about their homeostasis. Here we show that plasmablasts and plasma cells are always detectable in human blood at low frequency in any unimmunized dono
Fungi are among the most diverse and ecologically important kingdoms in life. However, the distributional ranges of fungi remain largely unknown as do the ecological mechanisms that shape their distributions1,2. To provide an integrated view of the spatial and seasonal dynamics of fungi, we implemented a globally distributed standardized aerial sampling of fungal spores3. The vast majority of oper
Introduction: Social robots are accompanied by high expectations of what they can bring to society and in the healthcare sector. So far, promising assumptions have been presented about how and where social robots are most relevant. We know that the industry has used robots for a long time, but what about social uptake outside industry, specifically, in the healthcare sector? This study discusses w
In language acquisition it is important to imitate the native speakers of the language. For the young child it is natural to imitate both the language and the behaviour of the culture. Imitation, or adaptation (Markham 1997), is also useful in second language acquisition to learn how to pronounce the words and to learn the prosody of the language. For most people it is difficult to learn to speak
Risk and vulnerability analyses are a required decision support tool in processes to improve societal safety and crisis preparedness at national, regional and local levels in several European states. Analyses result in risk images, which are the stakeholders’ views of events that must be addressed in planning processes related to topics such as land use and crisis management. Hence, risk and vulne
This dissertation shows how the intersection between German and Yiddish became an important but largely forgotten site of literary production in the long twentieth century. Beginning in the late eighteenth century, German and Yiddish came to be associated with divergent trajectories of Jewish modernity and were often understood to represent either side of a series of charged dichotomies, such as W
Couplings of microscopic stochastic models to deterministic macroscopic ordinary and partial differential equations are commonplace in numerous applications such as catalysis, deposition processes, polymeric flows, biological networks and parametrizations of tropical and open ocean convection. In this paper we continue our study of the class of prototype hybrid systems presented in [8]. These mode
This evaluation field study aims to study the LM International/Läkarmissionens and Adventist Development and Relief Agency (ADRA) Kenya’s project against Female Genital Mutilation/Cutting (FGM/C) in southwestern Kenya, a crime against human rights and a severe problem in parts of Kenya. The laws against FGM/C have had limited effect in the region, so the groundwork is more important than ever. The
The aim for this thesis is to find out what aspects are important to create a good sound environment at home. In order to do this three different sound environments has been studied in the literature review: hospitals, schools/pre-schools and offices. Important acoustical parameters was picked out and a method for evaluating the sound environment at home was carried out. The main subject was to fi
Kandidatuppsatsen undersöker vilka arbetstagargrupper som omfattas av kategorierna i undantagskretsen, 1 § andra stycket LAS, och vilka centrala konsekvenser det medför. Det finns fem kategorier av arbetstagare som undantas från lagen (1982:80) om anställningsskydd och uppsatsen undersöker vilka arbetstagare som omfattas av varje kategori. Uppsatsen redogör för dem centrala konsekvenser som medföThe bachelor thesis investigates which groups of employees that are included by the categories in the exception circuit in 1 § second subparagraph LAS and what central consequences it entails. There are five categories of employees that are excluded from LAS and the thesis investigates which employees are included in each category. The thesis describes the central consequences that entails with t
How do professional counselors understand and rationalize their responsibility to report child maltreatment when worried about a child? The aim of this study was to analyze how school counselors and health care counselors talk about their obligation to report child maltreatment to the social services, and how their reasoning affects the protection of children in Sweden. The method chosen was quali
Våld i samband med fotbollsmatcher har länge varit ett problem i Sverige. Den 30 mars 2014 nådde det sin kulmen när en Djurgårdssupporter misshandlades till döds i samband med en match mot Helsingborgs IF, vilket blev starten för en kris som drabbade både Helsingborgs IF och dess supporterförening Kärnan. Studien, som fokuserar på medlemsorganisationers kriskommunikation och organisations-samarbetFootball-related violence has been a problem in Sweden for a long time. On 30 March 2014 it reached its climax when a Djurgården supporter was killed in connection with a match against Helsingborgs IF, which started a crisis that affected both Helsingborgs IF and its supporters' association Kärnan. This study, which focuses on member organizations’ crisis communication and interorganizational
The aim of this study is to examine the determinants of capital structure via a cross-country comparison between the U.S.A. and Sweden. With the consideration of firm specific factors, the main focus is on researching country effect and macroeconomic impacts on firms’ financing policy. Including both country and macroeconomic factors in the research allows for having a new approach on the topic. T
This study treats Swedish university students view on responsibility for human rights that are affected badly by the global trading environment. Human rights can no longer be seen as a local matter between the state and the individual, as globalization, technology and new ways to communicate has given the world tools to both contributing to the violation and the promotion of human rights globally.
The higher education system of countries is an important area that determines the countries drive for development. This thesis aims to scrutinize the higher education system in Georgia and how the system translates and resonates with Georgia’s development. Several questions have been raised in light of the several reforms that have greeted the higher education system in Georgia and these questions
Due to changes in land use, as well as impacts from the climate change, our inland waters are now exposed to problems such as eutrophication and brownification. This complicates management to develop clean drinking water, as well as it leads to anoxic bottoms and reduces primary production. This literature review aims to see if wetlands can work as a natural filter to reduce both nutrients (nitrog
