   Abstract : By 2020 there will be 50 billion connected devices over the Internet. With the fast-increasing data traffic demand in both fixed and mobile networks, network operators need to migrate networks towards next generation solutions. READ MORE

4. 2. The roles of demography and natural selection in shaping genome-wide variation of Norway spruce

   Author : Xi Wang; Pär K. Ingvarsson; Carolina Bernhardsson; Xiao-Ru Wang; Nathaniel Street; Tanja Pyhäjärvi; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; whole-genome resequencing; variant calling; genetic linkage map; nucleotide diversity; natural selection;

   Abstract : Understanding the relative contribution of genetic drift, natural selection, and mutation to genetic variation, and quantifying adaptive evolution and the effects of natural selection in species are enduring goals of evolutionary genetics. Norway spruce (Picea abies) is one of the most important conifer species that dominates from both an ecological and economical point of view in many boreal ecosystems. READ MORE

5. 3. Hybridization and Evolution in the Genus Pinus

   Author : Baosheng Wang; Xiao-Ru Wang; Sally Aitken; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adaptation; biogeography; coalescent simulation; cytoplasmic genome; demographic history; genetic diversity; hybridization; migration; Pinus; population structure; selection; speciation; evolutionär genetik; evolutionary genetics;

   Abstract : Gene flow and hybridization are pervasive in nature, and can lead to different evolutionary outcomes. They can either accelerate divergence and promote speciation or reverse differentiation. The process of divergence and speciation are strongly influenced by both neutral and selective forces.

6. 4. Aspects of Moment Testing when p>n

   Author : Zhizheng Wang; Thomas Holgersson; Miguel Fonseca; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-dimensional data; Asymptotic distribution; Kolmogorov condition; Monte Carlo simulation; Hypothesis testing; Skewness and kurtosis; Statistics Econometrics; Statistik;

   Abstract : This thesis concerns the problem of statistical hypothesis testing for mean vector as well as testing for non-normality in a high-dimensional setting which is called the Kolmogorov condition. Since we consider mainly the first and the second moment in testing for mean vector and we utilize the third and the fourth moment in testing for non-normality, this thesis concerns a more general moment testing problem.

7. 5. On the role of mast cells in chemokine-induced leukocyte recruitment

   Author : Yusheng Wang; Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemokines; mast cells; TNF-alpha; dexamethasone; P-selectin; E-selectin; activation; Medicine human and vertebrates ; endothelial cells; adhesion; Neutrophil; Medicin människa och djur ; recruitment;

   Abstract : Leukocyte recruitment is considered to playa key role in numerous inflammatory diseases. Tissue accumulation of Jeukocytes is a multi-steps process comprising rolling, adhesion and transmigration. READ MORE
