  1. 1. Random tournaments and random circuits

    Författare :Pontus Andersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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.

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

    Författare :Pontus Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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

  4. 3. The Swedish Jews and the victims of Nazi terror, 1933–1945

    Författare :Pontus Rudberg; Lars M. Andersson; Margaret Hunt; Torkel Jansson; Bernard Wasserstein; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Modern Jewish history; Holocaust studies; Sweden; the Jewish community of Stockholm; refugees; humanitarian aid; Historia; History;

    Sammanfattning : This dissertation aims to provide new knowledge about Jewish responses to the Nazi persecutions and the Holocaust. This has been done through a study of the actions of the Jewish minority in Sweden during the Nazi era. LÄS MER

  5. 4. Mechanisms for TGF-β-Mediated Regulation of the Actin Filament System and Apoptosis

    Författare :Sofia Edlund; Pontus Aspenström; Maréne Landström; Tommy Andersson; Uppsala universitet; []
    Nyckelord :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

  7. 5. Exploring Road Traffic Interactions Between Highly Automated Vehicles and Vulnerable Road Users

    Författare :Victor Fabricius; Pontus Wärnestål; Jonas Andersson; Barry Brown; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automated driving system; Vulnerable road user; Traffic interaction; User Experience;

    Sammanfattning : Understandings of road traffic interactions are largely based on human-human interactions. However, the development of vehicles controlled by highly auto- mated driving systems (ADS) would introduce a radically novel type of road user. LÄS MER
