We study statistical properties of the 0+ spectrum of 208Pb in the energy region Ex ≤ 20 MeV. We use the Skyrme interaction SLy4 as our model Hamiltonian to create a single-particle spectrum and to analyze excited states. The finite-rank separable approximation for the particle–hole interaction enables us to perform the calculations in large configuration spaces. We show that while the position of
In a sample data system we are essentially restricted to control signals which are constant over the sampling interval. The purpose of this report is to analyze the effect of this restriction. The situation where the admissible control signals are piecewise continuous is used as a reference case and the problem is approached from a variational formulation of the control problem where the object o
Ultrafast extreme-ultraviolet (XUV) and X-ray sources are revolutionizing our ability to follow femtosecond processes with ångström-scale resolution. The next frontier is to simultaneously control the direction, duration and timing of such radiation. Here, we demonstrate a fully functional opto-optical modulator for XUV light, similar to modulators available at infrared (IR) and visible wavelength
Distributed computing infrastructures have a long history, starting with pools of PCs and clusters three decades ago, briefly passing a stage of HPC Grids, and now converging to fully virtualised facilities. The Nordic Tier-1, prototype of which was launched back in 2003 to serve CERN needs, is a small-scale model of a distributed infrastructure, and thus an interesting case for studying experienc
We have characterized the dissolved state of microcrystalline cellulose (MCC) in cold alkali [2.0 M NaOH(aq)] solutions using a combination of small angle X-ray (SAXS) and static light scattering (SLS), (Formula presented.)H NMR, NMR self-diffusion, and rheology experiments. NMR and SAXS data demonstrate that the cellulose is fully molecularly dissolved. SLS, however, shows the presence of large c
This study examines the sharing of research tools among academic scientists in the life sciences and materials sciences in Japan. First, this study investigates material transfer, or the sharing of research tools, based on individual-level negotiation. Statistical analyses suggest that supplier-side scientists decide whether or not to fulfill requests for material transfer on the basis of: expecte
PurposeThe purpose of this paper is to examine the transition of a place brand identity from a cultural anthropological perspective. More specifically, the paper analyses the ritual features and magical qualities of the development process of a regional brand in Scandinavia.Design/methodology/approachThe study consists of an exploratory, longitudinal single case study of regional branding. An abdu
