Validation strategies for the interpretation of microstructure imaging using diffusion MRI

Extracting microanatomical information beyond the image resolution of MRI would provide valuable tools for diagnostics and neuroscientific research. A number of mathematical models already suggest microstructural interpretations of diffusion MRI (dMRI) data. Examples of such microstructural features could be cell bodies and neurites, e.g. the axon's diameter or their orientational distribution for

Endometrial cancer off-line staging using two-dimensional transvaginal ultrasound and three-dimensional volume contrast imaging : Intermethod agreement, interrater reliability and diagnostic accuracy

Objectives: The aim is to estimate agreement between two-dimensional transvaginal ultrasound (2D-TVS) and three-dimensional volume contrast imaging (3D-VCI) in diagnosing deep myometrial invasion (MI) and cervical stromal involvement (CSI) of endometrial cancer and to compare the two methods regarding inter-rater reliability and diagnostic accuracy. Methods: Fifteen ultrasound experts assessed off

What does maintenance of infrastructure mean for pedestrians and cyclists – A knowledge summary

This report summaries knowledge concerning the impact of the maintenance of bicycle and pedestrian infrastructure. The aim of the literature review was to compile existing knowledge on operation and maintenance of the transport infrastructure for pedestrians and cyclists, the highlight how operation andmaintenance affect pedestrians and cyclists, in terms of accessibility, safety and security.

Effects of the Urban Environment on Oxidative Stress in Early Life : Insights from a Cross-fostering Experiment

As urban areas expand rapidly worldwide, wildlife is exposed to a wide range of novel environmental stressors, such as increased air pollution and artificial light at night. Birds in highly polluted and/or urbanized habitats have been found to have increased antioxidant protection, which is likely important to avoid accumulation of oxidative damage, which can have negative fitness consequences.

The small people in the big picture : Children in Swedish working-class novels of the 1930s

When the story of Scandinavian literature is being told in an international context, the Swedish proletarian novels of the 1930s are frequently held up as the more important of the regional canon. 1 In these celebrated novels, childhood and children are at the center-so much so, that I would suggest that the child is one of the more prominent motifs of Swedish literature between the two World Wars

Thermal design of an electric road system

Electric road systems (ERS) have the potential to be the next step in charging infrastructure for electric vehicles. To be able to dynamically charge electric vehicles, would not only extend the electric vehicles range but also reduce their need for large battery packs. Despite the relatively high efficiency of the ERS, the generated losses result in a great amount of heat, making the thermal prop

Stockholm the narcissistic capital of sweden

Since 2005, a Stockholm-based place branding network has tried to convince the world that Stockholm is the Capital of Scandinavia. Not surprisingly, the brand has been subject to massive criticism from its Scandinavian neighbours, but also internally from within the Stockholm region. Instead of listening to this critique, however, the network continues with its deceitful activities and retains its

Societal cost of electrifying all danish road transport

Electric Road Systems (ERS) have emerged as an alternative to deal with the main drawbacks that battery electric vehicles present (i.e., higher cost, short driving range, long charging times, etc.). This paper analyses the societal cost of electrifying all road transport in Denmark under four different scenarios. The first scenario considered in this study is based on todays approach of having ele

Resonance Enhancement with Antenna Modeling

This paper develops theory for an iterative experimental approach to use one or more antennas to identify resonances of a scattering system, which could consist of the antennas and one or more scattering objects. We include realistic mathematical models for the antennas and for target(s), and we show that the resonances include effects from the antennas and wave propagation as well as the target s

Inledning

Många medarbetare i offentlig sektor upplever att de inte får chansatt hjälpa medborgare som de skulle vilja. De vittnar om hur vårtsätt att styra och leda välfärdssektorn i dag alltför ofta leder tillmotsatta effekter mot de önskade. Bland annat handlar det omstora mängder mål och indikatorer i styrningen, ökad administrativbörda, detaljreglering, stuprörstänkande och krympande handlingsutrymmefö

Vad är tillitsbaserad styrning och ledning?

Grundidén med tillitsbaserad styrning och ledning är att öka kvaliteteni offentligt finansierade tjänster genom att öka handlingsutrymmeti mötet mellan medborgare och medarbetare. I detta kapitelutvecklas ett ramverk för att visa hur idén om tillit kan översättas ikonkret praktik. Uttrycket tillitsbaserad styrning och ledning definierasoch jag förklarar hur det ska förstås som ett samspel mellanku
