Wobbling excitations at high spins in A~160

We found that in 156Dy and 162Yb the lowest odd spin gamma-vibrational states transform to the wobbling excitations after the backbending, associated with the transition from axially-symmetric to nonaxial shapes. The analysis of quadrupole electric transitions determines uniquely the sign of the gamma-deformation in both nuclei after the transition point.Comment: 6 pages, 4 figure

Map-based multicriteria analysis to support interactive land use allocation

This article focuses on the use of map-based multicriteria analysis to develop a negotiation support tool for land use allocation. Spatial multicriteria analysis is used to make explicit trade-offs between objectives and to provide guidance and feedback on the land use changes negotiated by the participants. Digital maps are the means of communication among workshop participants, and an interactive mapping device (the 'Touch table') is used as the interface. Participants are informed about the relevant trade-offs on the map and use this information to change the land use maps. The approach is tested during a negotiation session as part of the land use planning process of the Bodegraven polder, a peat meadow area in the Netherlands. © 2011 Copyright Taylor and Francis Group, LLC

Quantum theta functions and Gabor frames for modulation spaces

Representations of the celebrated Heisenberg commutation relations in quantum mechanics and their exponentiated versions form the starting point for a number of basic constructions, both in mathematics and mathematical physics (geometric quantization, quantum tori, classical and quantum theta functions) and signal analysis (Gabor analysis). In this paper we try to bridge the two communities, represented by the two co--authors: that of noncommutative geometry and that of signal analysis. After providing a brief comparative dictionary of the two languages, we will show e.g. that the Janssen representation of Gabor frames with generalized Gaussians as Gabor atoms yields in a natural way quantum theta functions, and that the Rieffel scalar product and associativity relations underlie both the functional equations for quantum thetas and the Fundamental Identity of Gabor analysis.Comment: 38 pages, typos corrected, MSC class change

Reliability of voluntary step execution behavior under single and dual task conditions

<p>Abstract</p> <p>Background</p> <p>The current study investigated the repeatability (test-retest reliability) of ground reaction force parameters recorded during a voluntary step execution under single (motor task) and dual task (motor and cognitive task) conditions for healthy adults and elderly individuals as well as the number of trials required to produce repeatable results.</p> <p>Methods</p> <p>Twenty-four healthy adults (21–63 years old) and 16 elderly adults (66–87 years) performed a voluntary rapid step execution following a tap on their heel while standing on a force platform under single and dual task conditions on three separate occasions. The first two tests were performed 30–60 minutes apart and the third test was performed a week later. Variables analyzed from the ground reaction force data included onset latency of step initiation (initiation phase), preparation and swing phases, foot-off and foot-contact times.</p> <p>Results</p> <p>Intraclass correlation coefficients (ICC(2,1)) were good to excellent across all parameters and test conditions for the pooled population and for elderly (0.74–0.92 and 0.62–0.88, respectively) except for the swing phase duration where lower values were seen (0.54–0.60 and 0.32–0.64 respectively). Values were similar under single and dual task conditions.</p> <p>Conclusion</p> <p>A voluntary step execution test, performed under single and dual task conditions especially foot-off and foot-contact times, is a reliable outcome measure that may be a useful tool to asses dynamic balance function for diagnostic purposes as well as clinical intervention trials.</p

Habitattypen in Natura 2000-gebieden : beoordeling van oppervlakte, representativiteit en behoudsstatus in de Standard Data Forms (SDFs)

In dit rapport wordt een onderbouwing gegeven van de zogenaamde Standaard Data Forms (SDF’s) vanhabitattypen van de Annex I van de Habitatrichtlijn. Deze SDF’s maken onderdeel uit van de database over de Natura 2000-gebieden in ons land. De database speelt een rol bij eventuele juridische procedures en wordt door de Europese Commissie gebruikt om de voorstellen voor Natura 2000-gebieden van EU-lidstaten te beoordelen. In dit rapport is aangegeven op welke informatie de ecologische gegevens van de habitattypen in de Natura 2000-gebieden zijn beoordeeld. Het betreft gegevens over de oppervlakte van een habitat, de representativiteit, de relatieve oppervlakte ten opzichte van de oppervlakte in heel Nederland, de behoudsstatus van het habitattype, en een algemene evaluatie. Deze gegevens zijn aan de hand van uitgebreide maatlatten gescoord voor alle habitatrichtlijngebieden waarin een habitattype voorkomt. In totaal gaat het om ruim 1130 combinaties van habitattypen en gebieden
