In the age of miniaturization where the physical systems approach the nanoscale limit andwhere more complex materials are created there is necessity for understanding in terms ofquantum mechanics. The understanding then opens and gives possibilities for manipulationand engineering of such systems and thus practical applications.Quantum mechanics states that the electron cannot be characterized as In this thesis we focus on improvements of the description of the electron-electron correlation effects in nonequilibrium nanosystems. We mainly focus on developments of two nonequilibrium methods, namely the formalism of Nonequilibrium Green’s Function and Time Dependent Density Functional Theory and we explore the possibility to improve existing approximations in these theories. A smaller part o

Internet Metaphors and Norms. To what extent is digital “openness” also creating a modern “Panopticon”? I.e. to what extent is the conceptual imaginary of relevance for the legitimacy of modern data practices in terms of privacy? This paper argues that conceptual battles around what the Internet is and the digital development means are significant battles. The metaphorical descriptions of the inte

B-cell malignancies (BCM) originate from the same cell of origin, but at different maturation stages and have distinct clinical phenotypes. Although genetic risk variants for individual BCMs have been identified, an agnostic, genome-wide search for shared genetic susceptibility has not been performed. We explored genome-wide association studies of chronic lymphocytic leukaemia (CLL, N = 1,842), Ho

Background: An early report on the molecular subtyping of muscle-invasive bladder cancer (MIBC) by gene expression suggested that response to neoadjuvant chemotherapy (NAC) varies by subtype. Objective: To investigate the ability of molecular subtypes to predict pathological downstaging and survival after NAC. Design, setting, and participants: Whole transcriptome profiling was performed on pre-NA

Background: PSP is a neuropathologically defined disease entity. Clinical diagnostic criteria, published in 1996 by the National Institute of Neurological Disorders and Stroke/Society for PSP, have excellent specificity, but their sensitivity is limited for variant PSP syndromes with presentations other than Richardson's syndrome. Objective: We aimed to provide an evidence- and consensus-based rev

Mitochondrial genomes are separated from the nuclear genome for most of the cell cycle by the nuclear double membrane, intervening cytoplasm, and the mitochondrial double membrane. Despite these physical barriers, we show that somatically acquired mitochondrial-nuclear genome fusion sequences are present in cancer cells. Most occur in conjunction with intranuclear genomic rearrangements, and the f

The discovery, at the beginning of the 20th century, that elements can transform into other elements, due to the spontaneous decay of an instable to a stable atomic nuclei, gave rise to a powerful source for age information in many fields of earth science. For impact structures, it is crucial to establish well-defined and precise ages in order to understand how impact events affect the Earth’s geoThe discovery, at the beginning of the 20th century, that elements can transform into other elements, due to the spontaneous decay of an instable to a stable atomic nuclei, gave rise to a powerful source for age information in many fields of earth science.

At the time of cancer diagnosis, body mass index (BMI) is inversely correlated with lung cancer risk, which may reflect reverse causality and confounding due to smoking behavior. We used two-sample univariable and multivariable Mendelian randomization (MR) to estimate causal relationships of BMI and smoking behaviors on lung cancer and histological subtypes based on an aggregated genome-wide assoc

The aim of the study presented in this report was to investigate what cues cyclists use to interpret the intention of motor vehicles (MVs) they interact with. This was done with help of on-site observations of cyclists’ interactions with motor vehicles (MV) at signalised intersections with different bicycle infrastructure facilities: A) no dedicated cycle facility, B) cycle lane and C) cycle path.The aim of the study presented in this report was to investigate what cues cyclists use to interpret the intention of motor vehicles (MVs) they interact with.

The ubiquitous skin colonist Staphylococcus epidermidis elicits a CD8+ T cell response pre-emptively, in the absence of an infection1. However, the scope and purpose of this anticommensal immune programme are not well defined, limiting our ability to harness it therapeutically. Here, we show that this colonist also induces a potent, durable and specific antibody response that is conserved in human

Background:With a rapidly ageing population, the number of wrist fractures will rise dramatically in the super-elderly (>80 years) group. In previous published studies regarding mortality after wrist fractures elderly are often defined using a rather wide age-span, the threshold has been set to somewhere between 50-70 years. However, elderly defined as a group this way is probably too imprecise. D

Popular Abstract in Swedish Förmågan hos levande vävnader att läka skador är en basal faktor för överlevnad och utgör grundförutsättningen för all kirurgisk verksamhet. Det finns lokala skillnader beträffande celltyper och tidsförlopp, men mycket talar för att sårläkningsprocessen är principiellt likartad i alla vävnader. Sårläkning indelas i olika faser, varav den första utgöres av en inflammatorWound healing is a multistep process with an initial inflammatory response, followed by synthesis of extracellular matrix components and finalized by a repair phase. One main goal was to determine the impact and adhesive mechanisms of neutrophil recruitment in anastomotic healing in the colon. Passive immunization against CD18 abolished anastomotic accumulation of neutrophils, whereas no effect on

Popular Abstract in English The work presented here is about methods that will enable more precise estimates of soil and rock parameters related to seismic hazard mapping, in particular when resources are limited. This will allow for evaluating the seismic risk in countries where earthquakes are frequent and large budgets are not available. Particularly, the study of ground response due to the eneIn sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. In common practice the active MASW method is implemented using a sledgehammer source and a linear receiver spread. This method is lim
