We present experimental data on the time and radius-dependent length distributions of Au-catalyzed InAs nanowires grown by metal organic vapor phase epitaxy. We show that these distributions are not as sharp as commonly believed. Rather, they appear to be much broader than Poissonian from the very beginning and spread quickly as the nanowires grow. We develop a model that attributes the observed b

We study System Optimum Dynamic Traffic Assignment (SO-DTA) for realistic traffic dynamics controlled by variable speed limits, ramp metering, and routing controls. We consider continuous-time cell-based Dynamic Network Loading models that include the Cell Transmission Model with FIFO rule at the diverge junctions as well as non-FIFO diverge rules. We consider SO-DTA formulations in which the tota

Disrupted high school experiences, including dropout, are educational consequences for many youth with histories of homelessness. Using an ecological resilience prediction model (ERPM) based on the literature on resilience in at-risk youth, the study followed 82 youth who were initially homeless for a 2-year period, to identify predictors of participating in school. Female sex and increased durati

A complex interplay between the microbiota and the host immune system is evidenced to shape the immune system throughout life, but little is known about the microbial effect on key players of the adaptive immune system, the B2 B cells. In the presented study, we have evaluated the effect of commensal bacteria on B cell ontogeny and function, with the focus on B2 B cells of spleen and Peyer's patch

Postnatal intestinal development is a very dynamic process characterized by substantial morphological changes that coincide with functional adaption to the nutritional change from a diet rich in fat (milk) to a diet rich in carbohydrates on from weaning. Time-resolved studies of intestinal development have so far been limited to investigation at the transcription level or to single or few proteins

The general objective of this thesis was to increase the knowledge of how mental health and school performance are associated and how interventions may be designed and implemented to enhance the two.The data used in the four quantitative studies on which this thesis is based were derived from two age cohorts of students attending 14 elementary schools in two cities in the southern part of Sweden.

Aim: To describe drug use and healthcare utilisation among persons with intellectual disabilities (ID) and dementia in comparison to persons with ID only and dementia only. Method: From the group of persons with ID (n=7936), 216 individuals with dementia were identified. 81 persons with dementia were identified from a general population sample matched by age and sex. Information on outcomes was co

Background: Several countries have increased patients' abilities to choose their health care providers, frequently under the assumption that patients are themselves the best agents to make such decisions. In parallel, national and regional health authorities have enhanced access to Internet based information sources (IBIS) to assist patients in making an informed choice. Relatively little, however

Several strategic interactions over social networks display both negative and positive externalities at the same time. E.g., participation to a social media website with limited resources is more appealing the more of your friends participate, while a large total number of participants may slow down the website (because of congestion effects) thus making it less appealing. Similarly, while there a

Recently observed Arctic greening trends from normalized difference vegetation index (NDVI) data suggest that shrub growth is increasing in response to increasing summer temperature. An increase in shrub cover is expected to decrease summer albedo and thus positively feed back to climate warming. However, it is unknown how albedo and NDVI are affected by shrub cover and inter-annual variations in

The aim of this article is to analyze reported changes in outdoor mobility, increased/unchanged/decreased, for a sample of older people (>62 years) in two regions in Sweden, who have transitioned from a two-person to a single-person household during the two years since the study was conducted. The target group (N=162) consists of all people who had transitioned to a single-person household in a ra

Catalysis is a powerful tool to highly efficient production of desired newchemicals by acceleration of a chemical reaction rate. Special compounds used forthis purpose are called catalysts; they induce a change in the chemicalenvironment without being consumed during the process. Catalysis affects manyfields of life leading to a decrease of the energy use, less pollution, fewer sideproducts and loCatalysis is a powerful tool to highly efficient production of desired newchemicals by acceleration of a chemical reaction rate.

This dissertation examines the changing time allocation of men and women at the turn of the 21st century in Sweden, an interesting case given its strong position concerning female labor force participation, maternal employment, and gender equality. The aim is to examine to what extent gender and parenthood affect various types of time allocation, both in the labor market and household, and provide

Aim: Life expectancy of people with intellectual disability (ID) has increased along with that in the general population. The aims were to estimate prevalence of older people with intellectual disabilities (ID) during 2004-2012, and identify differences in prevalence across counties in Sweden. Method: Individuals aged 55+ years were identified through two national registers; the LSS register and t
