Significant extensions to the high-spin excitation spectrum of the N = 91, 92, 93 isotopes Dy-157,Dy-158,Dy-159 have been achieved using the high-efficiency gamma-ray spectrometers Euroball and Gammasphere. These nuclei were populated via weak 3n or alpha xn exit channels in fusion evaporation reactions. In Dy-157, the yrast band has been extended to I-pi = (2)/(101+) (tentatively to (2)/(105+)) w

An introduction to a book on village formation and village structure during the Middle Ages in Scania, that puts the following studies in a wider framework focussing on issues of aristocratization and urbanization and on larger cycles of expansion and regression in the Eurasian world. The text also argues that the Swedish or Nordic periodization of the Middle Ages should be abandoned in favour of

Several physical phenomena cannot be described with a linear model. We present a couple of such phenomena related to electromagnetics, and give several examples of how they can be modeled mathematically. The emphasis is on different representations of the constitutive functional and the analysis of its combination with the time-domain Maxwell equations.

We have grown InAs quantum dots on the {110} cleaved edges of (001) GaAs wafers. The lattice mismatch drives the formation of the quantum dots in a Stranski-Krastanow growth mode. We have investigated the properties of the resulting structures by atomic force microscopy, scanning electron microscopy, transmission electron microscopy and low-temperature cathodoluminescence. The growth of GaAs on th
