In this study, we investigate which factors affect the false positive fraction (FPF) for digital breast tomosynthesis (DBT) compared to digital mammography (DM) in a screening population by using classification and regression trees (C&RT) and binary marginal generalized linear models. The data was obtained from the Malmö Breast Tomosynthesis Screening Trial, which aimed to compare the performa
Palaeoecological analysis of peat deposits from a small bog at Lingarden, southern Sweden, have been used to examine the nature and timing of vegetation changes and anthropogenic activity associated with a nearby rock carving located close to the edge of the wetland. This study is the first of its type to investigate the environmental context of rock carvings in southern Sweden. Debate has tended
The atmospheric concentration of elemental carbon (EC) in Europe during the six-year period 2005-2010 has been simulated with the EMEP MSC-W model. The model bias compared to EC measurements was less than 20% for most of the examined sites. The model results suggest that fossil fuel combustion is the dominant source of EC in most of Europe but that there are important contributions also from resid
In this paper, the freeze-thaw stability of mayonnaise type oil-in-water emulsions is studied. The emphasis of the experiments have been on the properties of the dispersed oil phase as only small, or no effects, were observed from initial experiments on changing the properties of the aqueous phase within the investigated ranges. Different vegetable oils are investigated in order to relate the comp
This paper concerns the operational activities of the public security organs of the People’s Republic of China (PRC) during the immediate post-1949 period of regime consolidation. The main part of the paper is a case-study of a 1950 pilot scheme to recruit agents in critical sectors of industry and trade in the city of Yingkou in Northeast China, a scheme in due course subsumed under a nationwide
The early modern period has so far received little attention from archaeologists and anthropologists in Sweden. This study explores demographic patterns, social differences, family structure and mobility in a 16th-century skeletal population (n=102) from a preindustrial mining community (Salberget) in Bergslagen, Sweden, using a bioarchaeological perspective. Methodologically, the results of stron
The Storo greenstone belt in Godthabsfjord, southern West Greenland consists of juxtaposed rock units of different age and origin, and hosts gold mineralisation that is associated with arsenopyrite along a contact between lithological units and along the axial plane of a large fold core. The age and origin of the gold is debatable, but in this paper, we present new arsenopyrite Re-Os and zircon U-
Understanding the genetic consequences of changes in population size is fundamental in a variety of contexts, such as adaptation and conservation biology. In the study presented here, we have performed a replicated experiment with the plant Nigella degenii to explore the quantitative genetic effects of a single-founder bottleneck. In agreement with additive theory, the bottleneck reduced the mean
The Vel antigen is present on red blood cells (RBCs) from all humans except rare Vel-negative individuals who can form antibodies to Vel in response to transfusion or pregnancy. These antibodies may cause severe hemolytic reactions in blood recipients. We combined SNP profiling and transcriptional network modeling to link the Vel-negative phenotype to SMIM1, located in a 97-kb haplotype block on c
The final ATLAS Run 1 measurements of Higgs boson production and couplings in the decay channel H -> ZZ* -> l(+)l(-)l(+)l'(-), where l, l' = e or mu, are presented. These measurements were performed using pp collision data corresponding to integrated luminosities of 4.5 and 20.3 fb(-1) at center-of-mass energies of 7 and 8 TeV, respectively, recorded with the ATLAS detector at the LHC. The H -> ZZ
The use of ground-source heat pumps for heating and domestic hot water in dwellings is common in Sweden. The combination with solar collectors has been introduced to reduce the electricity demand in the system. In order to analyze different systems with combinations of solar collectors and ground-source heat pumps, computer simulations have been carried out with the simulation program TRNSYS. Larg
Popular Abstract in Swedish Vård och behandling av akut postoperativ och cancer-relaterad smärta: Patienters erfarenheter och uppfattningar i förhållande till hälsorelaterad livskvalitet och smärtans dimensioner Trots att det finns effektiva behandlingsmetoder för patienter med postoperativ smärta och cancer-relaterad smärta så lider många patienter av smärta. Denna avhandling beskriver patienterThis thesis describes patients in acute postoperative pain as well as patients with acute cancer-related pain in palliative care, and their experiences and perceptions of pain management in relation to HRQOL and the multidimensionality of pain. A combination of qualitative and quantitative methods was chosen. Data were collected using interviews and questionnaires; APS, SF:36 and a new developed q
Mycorrhizal symbioses are formed between plant root systems and compatible fungal hyphae that results in a complex mixed structure. They are found in all ecosystems and with the majority of land plants such as forest trees or crops that are of commercial interest. Mutual exchange of nutrients between the two symbionts is central to the successful functioning of the symbioses. In order to understan
In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two var
Popular Abstract in Swedish Syftet med den här studien var att undersöka det strukturella underlaget för förslagen att makrofager och gaserna kvävemonooxid (NO) och kolmonoxid (CO), som bildas av kvävemonooxidsyntaser (NOS) respektive hemeoxygenaser (HO), är viktiga för att en perifer nerv ska regenerera. Det finns stöd för dessa hypoteser eftersom andra har visat att förhållanden som stör den invThe purpose of this study was to investigate the suggestions that macrophages, and the systems generating nitric oxide (NO) and carbon monoxide (CO), i.e. nitric oxide synthases (NOS) and heme oxygenases (HO), could be important for peripheral nerve regeneration. Immunocytochemistry was used to visualise invading and resident macrophages, inducible NOS (iNOS), two isoforms of HO (HO-1 and HO-2),
OBJECTIVE: We examined the association between total tooth loss and bone mineral density to determine whether the former can be used as a surrogate marker of the latter. DESIGN: A community based cross-sectional survey. SETTING: The community-study area of the Faculty of Medicine, Galle. PARTICIPANTS: A group of randomly selected 327 women volunteers aged 32 to 97 years. MEASUREMENTS: Anthropometr
We present a new type of nanometer-scale semiconductor nonlinear device, called self-switching device (SSD). The device was realized by simply etching insulating grooves into a semiconductor, between which a narrow channel with a broken symmetry was formed. Because of the asymmetry in the channel boundary, an applied voltage V not only changes the potential profile along the channel direction, but
