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
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

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.
