  1. 1. Random tournaments and random circuits

    Författare :Pontus Andersson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Mathematics; Poisson-Dirichlet distribution; random circuit decomposition; random tournament; subgraph count; MATEMATIK; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : This thesis is devoted to two different topics in the area of probabilistic combinatorics: asymptotic behaviour of subgraph counts in a random tournament and random circuit decompositions of complete graphs.Let Tn be a random tournament on n vertices, chosen uniformly from all 2(n2) such tournaments, and let D be an arbitrary directed graph.

  2. 2. Laser Photodetachment of Negative Ions - Fundamental Research and Applications

    Författare :Pontus Andersson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Negative Ions; Laser Spectroscopy; Photodetachment; Electron Affinity; Mass Spectrometry; Radiative Lifetime; Storage Rings; Mass Spectrometry;

    Sammanfattning : Photodetachment studies of atomic and molecular negative ions in the gas phase are presented. Negative ions are loosely bound quantum systems whose existence is strongly dependent on the correlations between the electrons. LÄS MER

    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; TGF-beta; cytoskeleton; GTPases; mitogen-activated protein kinase kinase 3; TGF-beta-activated kinase 1; Apoptosis; Smad7; beta-catenin; p38 MAPK; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Transforming growth factor-β (TGF-β) is a member of a large superfamily of cytokines which participate in many different types of cellular processes, such as growth inhibition, cell migration, differentiation, cell adhesion, wound healing and immunosuppression. Alterations of TGF-β superfamily signalling results in several different disorders, including bone disease, vascular disease and cancer. LÄS MER
