  2. 1. Asymptotic and universal spectral estimates with applications in many-body quantum mechanics and spectral shape optimization

    Author : Simon Larson; Ari Laptev; Stefan Steinerberger; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spectral theory; shape optimization; semiclassical asymptotics; spectral inequalities; quantum mechanics; Mathematics; Matematik;

    Abstract : This thesis consists of eight papers primarily concerned with the quantitative study of the spectrum of certain differential operators. The majority of the results split into two categories. READ MORE

  4. 2. Communication and Cooperation : A Study of the Relationship Between Political Communication and Large-scale Collective Action

    Author : Stefan Linde; Simon Matti; Sverker Jagers; Carina Lundmark; Lisa Dellmuth; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Collective Action; Political Communication; Climate Change; Political Science; Statsvetenskap;

    Abstract : This thesis investigates the importance of communication for individual cooperation in large-scale collective action dilemmas. In small-scale collective action, where participants have the possibility to meet face-to-face, communication has been shown to drastically increase levels of cooperation. READ MORE

  5. 3. Exploring the tissue-specific nature of the Wnt cell signaling system : The complex world of cell communication and the search for the Achilles heel of cancer

    Author : Simon Söderholm; Claudio Cantù; Mikael Benson; Stefan Hoppler; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wnt signaling; β-catenin; Development; Cancer; Stem cells; Omics; Bioinformatics;

    Abstract : The Wnt signaling pathway is a biological mechanism for cell-cell communication found across all species of the animal kingdom. This pathway plays a major role in virtually all stages of embryonic development, and it governs central aspects of stem cell biology, regeneration, and tissue homeostasis. READ MORE

  6. 4. Towards energy-based fracture modelling for crashworthiness applications

    Author : Simon Jonsson; Jörgen Kajberg; Stefan Golling; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : The automotive industry is currently adapting to progessively more stringent emission and safety regulations imposed by governmental agencies. This introduces significant design difficulties due to the conflicting nature of passenger safety in automotive manufacturing, namely that increased crashworthiness generally leads to heavier vehicles, which in turn leads to more severe crashes.

  7. 5. Ashes to ashes : Applications of tephrochronology in Scandinavia

    Author : Simon A. Larsson; Stefan Wastegård; Britta Sannel; Christine Lane; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tephrochronology; tephrostratigraphy; tephra; palaeoclimate; Last Glacial–Interglacial Transition; Scandinavia; naturgeografi; Physical Geography;

    Abstract : The project presented in this thesis provides two examples of applications of tephrochronology in Scandinavia. The usage of tephra deposits preserved in sediments—i.e. READ MORE
