  1. 1. My first-passage : target search in physics and biology

    Författare :Markus Nyberg; Ludvig Lizana; Martin Rosvall; Carlos Mejia-Monasterio; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; first-passage; mean first-passage time; mean first-arrival time; random walk; diffusion; zero-crossing; persistence; survival probability; network; resetting; teoretisk fysik; Theoretical Physics;

    Sammanfattning : Random walks and diffusing particles have been a corner stone in modelling the random motion of a varying quantity with applications spanning over many research fields. And in most of the applications one can ask a question related to when something happened for the first time. That is, a first-passage problem. LÄS MER

  2. 2. At first blush : the impact of shyness on early adolescents' social worlds

    Författare :Nejra Besic; Margaret Kerr; Håkan Stattin; Ray Crozier; Örebro universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; shyness; adolescence; social relationships; friends; peers; parents; social identity; socialization; problem behaviors; Psychology; Psykologi; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Social sciences; Socialvetenskap; Psykologi; Psychology;

    Sammanfattning : Shyness as a behavioral characteristic has been in focus of research in psychology for a number of decades. Adolescent shyness has, however, been relatively overlooked compared with studies conducted on children and adults. LÄS MER

  3. 3. The first injustice : Socio-economic inequalities in birth outcome

    Författare :Marit Gisselmann; Denny Vågerö; Magnus Nermo; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Sweden; socio-economic inequalities; birth outcome; infant mortality; low birthweight paradox; working conditions; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : Adverse birth outcomes like preterm birth and infant mortality are unevenly distributed across socio-economic groups. Risks are usually lowest in groups with high socio-economic status and increase with decreasing status. LÄS MER

  5. 5. Polar molecules in crystalline and surface environments : From first principles

    Författare :Maria Alfredsson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : With the knowledge of the composition and structure of a chemical system, be it a molecule, a two-dimensional surface or a three-dimensional crystal, it is now possible to predict the specific properties of the compound under consideration via computational studies. Molecular and periodic Hartree-Fock and DFT calculations have been used as a tool to study polar molecules and how their properties respond to the molecular environment in a crystal or on an ionic surface.
