In order to reduce the current hadronic uncertainties in the theory prediction for the anomalous magnetic moment of the muon, lattice calculations need to reach subpercent accuracy on the hadronic-vacuum-polarization contribution. This requires the inclusion of O(α) electromagnetic corrections. The inclusion of electromagnetic interactions in lattice simulations is known to generate potentially la
First-order perturbations of homogeneous and hypersurface orthogonal locally rotationally symmetric class II cosmologies with a cosmological constant are considered in the framework of the 1+1+2 covariant decomposition of spacetime. The perturbations, which are of perfect fluid type, include general scalar, vector, and tensor modes and extend some previous works in which vorticity perturbations we
Extended scalar and fermion sectors offer new opportunities for generating the observed strong hierarchies in the fermion mass and mixing patterns of the Standard Model (SM). In this work, we elaborate on the prospects of a particular extension of the Inert Higgs doublet model where the SM hierarchies are generated sequentially by radiative virtual corrections in a fully renormalisable way, i.e. w
In the spectrum of an emission-line region ejected from the massive star Eta Carinae, called the strontium filament (SrF), forbidden lines from many elements, in particular [Sr II] and [Ti II], are observed. These lines are strong in this specific region and valuable for plasma diagnostics. Forbidden lines are not easily produced in laboratory light sources and the atomic parameters for these line
The detection of electromagnetic (EM) emission following the gravitational wave (GW) event GW170817 opened the era of multi-messenger astronomy with GWs and provided the first direct evidence that at least a fraction of binary neutron star (BNS) mergers are progenitors of short Gamma-Ray Bursts (GRBs). GRBs are also expected to emit very-high energy (VHE, > 100 GeV) photons, as proven by the recen
High-energy gamma rays are promising tools to constrain or reveal the nature of dark matter, in particular Weakly Interacting Massive Particles. Being well into its pre-construction phase, the Cherenkov Telescope Array (CTA) will soon probe the sky in the 20 GeV - 300 TeV energy range. Thanks to its improved energy and angular resolutions as well as significantly larger effective area when compare
The Gaia spacecraft presents an unprecedented opportunity to reveal the population of long period (a > 1 au) exoplanets orbiting stars across the H-R diagram, including white dwarfs. White dwarf planetary systems have played an important role in the study of planetary compositions, from their unique ability to provide bulk elemental abundances of planetary material in their atmospheres. Yet, very
In this work we calculate the cross sections for the hadroproduction of a single top quark or antiquark in association with a Higgs (tHj) or Z boson (tZj) at NLO QCD+EW accuracy. In the case of tZj production we consider both the case of the Z boson undecayed and the complete final state tℓ+ℓ−j, including off-shell and non-resonant effects. We perform our calculation in the five-flavour-scheme (5F
Bone scintigraphy images are used to investigate the presence of metastases in patients with prostate cancer. An analysis of these images indicates the proportion of cancer in the bones; the Bone Scan Index (BSI). This value is an important prognostic factor used to predict the future for the patients. It is common to extend the examination with a combination of SPECT and CT images to be able to s
Global disease transmission is an important area, since knowledge of the time of the onset of an epidemic in a region might help authorities to save many lives. In this thesis I have used a deterministic model with eight parameters, of which two were time dependent, for spreading of the SARS disease. My model is an extension of a model by Colizza and co-workers, where I have added a Heaviside step
This rapport is a study in advance of a possible up and coming restoration of the old observatory in Lund. The rapport is based on the possibility that it will be restored to accommodate modern facilities and suit the needs and demands we have on a modern building regarding installations and accessibility. This rapport describes in detail how to transform and renovate the old observatory to house
Cambodia has struggled with discrimination and stigmatization for many years. This text examines the view of the Cambodian state on discrimination in relation to child health. The material that is studied is Cambodia’s combined second and third state report to the committee for the Convention of the Rights of the Child. The theoretical background to this examination is the discussion of redistribu
Immunohistochemical expression of CD40 is seen in 60-70% of diffuse large B-cell lymphoma (DLBCL) and is associated with a superior prognosis. By using gene expression profiling we aimed to further explore the underlying mechanisms for this effect. Ninety-eight immunohistochemically defined CD40 positive or negative DLBCL tumors, 63 and 35 respectively, were examined using spotted 55K oligonucleot

Våldtäktsbrottet är ett brott som i de allra flesta fall sker bakom stängda dörrar. Som konsekvens av detta blir bevissituationen svår, eftersom ord står mot ord. I de allra flesta fall finns varken vittnen eller annan direkt bevisning som kan styrka åtalet, vilket innebär att den enda direkta bevisningen i många fall består av en målsägandeutsaga. Det övergripande syftet med denna uppsats har varRape is a crime that in most cases occurs behind closed doors. As a consequence, the question of evidence is difficult, since often words are against words. In the vast majority of cases, there are neither witnesses nor other direct evidence that can substantiate the prosecution, meaning that the only direct evidence in many cases consists of the victim’s statement. The overall purpose of this the
