    In October 2008, Iceland experienced the fastest and deepest financial crisis recorded in modern times when all three major banks went bankrupt in less than 2 weeks. The purpose of this follow-up study is to examine potential changes in participation ...
  • Jónasson, Jón Torfi (Springer Nature, 2016-10-20)
    The point of departure of the paper is that there are profound social, cultural, technological, scientific and environmental changes which occur at most local but also at global levels of the modern world. From these will stem huge challenges in all ...

    Abstract Psoriasis is a chronic immune-mediated inflammatory skin disease with profound effects on psychosocial wellbeing. Narrowband UVB phototherapy is a known effective treatment for chronic plaque psoriasis and previous studies suggest an ...
  • Uzdin, Valery M.; Potkina, Maria N.; Lobanov, Igor S.; Bessarab, Pavel; Jónsson, Hannes (Elsevier BV, 2017-09)
    The stability of magnetic skyrmions against thermal fluctuations and external perturbations is investigated within the framework of harmonic transition state theory for magnetic degrees of freedom. The influence of confined geometry and atomic scale ...
