Breast tomosynthesis (BT) is an X-ray imaging technique recently introduced as an alternative or complement to standard digital mammography (DM) in breast imaging and breast cancer screening. In BT, a set of projection images is acquired over a limited angular range and reconstructed into a volume of slice images. The method includes many possible combinations of acquisition parameters that have t
Background: To assess the quality of life of people with dementia, measures are required for self-rating by the person with dementia, and for proxy rating by others. The Quality of Life in Alzheimer's Disease scale (QoL-AD) is available in two versions, QoL-AD-SR (self-rating) and QoL-AD-PR (proxy rating). The aim of our study was to analyse the inter-rater agreement between self- and proxy rating
We investigated multivoxel proton magnetic resonance spectroscopy (1H-MRS) biometrics for preoperative differentiation and prognosis of patients with brain metastases (MET), low-grade glioma (LGG) and high-grade glioma (HGG). In total, 33 patients (HGG, 14; LGG, 9; and 10 MET) were included. 1H-MRS imaging (MRSI) data were assessed and neurochemical profiles for metabolites N-acetyl aspartate (NAA
Avhandlingen behandlar den socialistiska respektive den liberala internationella fredsrörelse som agerade under kvartsseklet före första världskrigets utbrott 1914.During the 25 years before the First World War in 1914 two different kinds of peace movements, one bourgeois-liberal and one socialist, were organised to fight militarism and war. The two movements – represented by the International Peace Bureau and the Second International, respectively – grew in size between 1889 and 1914. At the beginning of 1914, IPB organized over 200 peace associations, repr
Background and Purpose- We evaluated deep learning algorithms' segmentation of acute ischemic lesions on heterogeneous multi-center clinical diffusion-weighted magnetic resonance imaging (MRI) data sets and explored the potential role of this tool for phenotyping acute ischemic stroke. Methods- Ischemic stroke data sets from the MRI-GENIE (MRI-Genetics Interface Exploration) repository consisting
Popular Abstract in Swedish Prosodi och intonation är viktiga delar i det mänskliga talet. I system för text-till-talomvandling och automatisk taligenkänning måste prosodiska modeller inkluderas för att uppnå acceptabla resultat. Denna avhandling bidrar till modelleringen av svensk prosodi ur lexikalt och akustiskt perspektiv. Tre aspekter av lexikal modellering av prosodi studeras. Vi skisserar Prosody and intonation are very important ingredients of human speech. In speech technology, text-to-speech (TTS) and automatic speech recognition (ASR) systems must incorporate prosodic models in order to reach acceptable performances. We contribute to the modelling of Swedish prosody in a speech technology context from lexical and acoustic angles. Three aspects of lexical prosodic modelling are
The doctoral thesis seeks to discuss the transition between Viking Age and early medieval settlement and the establishment of the historical villages, based on archaeological material collected in Halland. The development is described in terms of three general periods of change: Period 1, c. 800–1000, consisting of farms with three-aisled longhouses. Period 2, c. 1000–1150, a transitional period w
Particles can be used to stabilize multi-phase systems known as Pickering emulsions. The aim of this thesis was to investigate how starch particles affect emulsion properties. Starch granules were used individually as well as in binary mixtures. To obtain a wide variety of starch properties granules were selected based on botanic variation (quinoa, oat, waxy barley, waxy maize and potato). The pro
Introduction: In a cold,wet, or windy environment, cold exposure can be considerable for an injured or ill person. The subsequent autonomous stress response initially will increase circulatory and respiratory demands, and as body core temperature declines, the patient’s condition might deteriorate. Therefore, the application of adequate insulation to reduce cold exposure and prevent body core cool
Demand for plant products has increased in recent years. To produce a vegetable yogurt with good taste and with the right consistency is problematic without the milk protein casein. Product development of a vegetable yoghurt type product was made. Collaboration with Veg of Lund AB was performed on their currently existing products My Foodie blueberries, raspberry and sea buckthorn with a focus on
Evaporation is one of the main components of the hydrological cycle, and its estimation is crucial and important for water resources management issues. Access to a reliable estimator tool for evaporation simulation is important in arid and semi-arid areas such as Iran, which lose more than 70% of their received precipitation by evaporation. Current research employs the Bayesian Regularization (BR)
Intrinsically disordered proteins are distinguished by a lack of distinct three-dimensional structure, existing instead as an ensemble of heterogenous structures. In this research, the effect of crowding on these proteins is investigated using a combined approach of experiment and computer simulation, mainly using coarse-grained simulation models to make simulation computationally feasible at the
Quasi-elastic neutron scattering (QENS) and small angle neutron scattering (SANS), in combination with isotopic contrast variation, have been used to determine the structure and dynamics of three-component lipid membranes, in the form of vesicles, comprising an unsaturated [palmitoyl-oleoyl-phosphatidylcholine (POPC) or dioleoyl-phosphatidylcholine (DOPC)], a saturated phospholipid (dipalmitoyl-ph
Background: Lignosulfonates are significant wood chemicals with a $700 million market, produced by sulfite pulping of wood. During the pulping process, spent sulfite liquor (SSL) is generated, which in addition to lignosulfonates contains hemicellulose-derived sugars—in case of hardwoods primarily the pentose sugar xylose. The pentoses are currently underutilized. If they could be converted into v
Bacterial exopolysaccharides (EPS) have emerged as one of the key players in the field of heavy metal-contaminated environmental bioremediation. This study aimed to characterize and evaluate the metal biosorption potential of EPS produced by a novel Psychrobacillus strain, NEAU-3TGS, isolated from an iron ore deposit at Tamra iron mine, northern Tunisia. Genomic and pan-genomic analysis of NEA
Corrosion of embedded steel reinforcement is the prime influencing factor that deteriorates the structural performance and reduces the serviceability of reinforced concrete (RC) structures, especially during earthquakes. In structural elements, RC columns play a vital role in transferring the superstructure's load to the substructure. The deterioration of RC columns can affect the structures' over
Streptococcus bovis/Streptococcus equinus complex (SBSEC) is a common cause of infective endocarditis (IE). For IE-pathogens, the capacity to activate and aggregate platelets is believed to be an important virulence mechanism. While the interactions between bacteria and platelets have been described in detail for many Gram-positive pathogens, little research has been carried out with SBSEC in this
Mikrober finns överallt, runt omkring oss i vår miljö och inuti våra kroppar. De som lever tillsammans med djur har mycket stor påverkan på värdens hälsa och evolutionära fitness. Från ett djurs perspektiv är vissa mikrober goda, andra onda, och vissa har ingen större påverkan på hälsan, men egentligen beror dessa egenskaper på sammanhanget, eftersom det är vanligt att mikrober byter strategi tillThe microbes living inside hosts have highly important consequences for host health and fitness. From the host’s perspective, some microbes exhibit mutualistic tendencies, others parasitic, and some commensal, but this is context-dependent and opportunistic lifestyles are widespread in nature. Our knowledge of how hosts interact molecularly with different microbes is, however, poor, and little res
Aims. We aim to constrain the mixing processes in low-mass stars by investigating the behaviour of the Li surface abundance after the main sequence. We take advantage of the data from the sixth internal data release of Gaia-ESO, IDR6, and from the Gaia Early Data Release 3, EDR3s. Methods. We selected a sample of main-sequence, sub-giant, and giant stars in which the Li abundance is measured by th
