  abstract     = {{<jats:p>Helhmoltz–Kirchhoff equations of motions of vortices of an incompressible fluid in the plane define a dynamics with singularities and this leads to a Zermelo navigation problem describing the ship travel in such a field where the control is the heading angle. Considering one vortex, we define a time minimization problem which can be analyzed with the technics of geometric optimal control combined with numerical simulations, the geometric frame being the extension of Randers metrics in the punctured plane, with rotational symmetry. Candidates as minimizers are parameterized thanks to the Pontryagin Maximum Principle as extremal solutions of a Hamiltonian vector field. We analyze the time minimal solution to transfer the ship between two points where during the transfer the ship can be either in a strong current region in the vicinity of the vortex or in a weak current region. The analysis is based on a micro-local classification of the extremals using mainly the integrability properties of the dynamics due to the rotational symmetry. The discussion is complex and related to the existence of an isolated extremal (Reeb) circle due to the vortex singularity. The explicit computation of cut points where the extremal curves cease to be optimal is given and the spheres are described in the case where at the initial point the current is weak.</jats:p>}},

  abstract     = {{<jats:p> Zusammenfassung. Im vorliegenden Beitrag wird die theoriegeleitete Entwicklung und Erprobung eines Instrumentes zur standardisierten Erfassung von Planungskompetenzen angehender Lehrkräfte im Fach Sachunterricht dokumentiert, auf dessen Grundlage das in Nordrhein-Westfalen 2015 als Teil des Masterstudiums implementierte Praxissemester hinsichtlich der damit intendierten Ausbildung von Planungsfähigkeiten evaluiert werden soll. Ausgehend von einem Rahmenmodell, das die Instrumententwicklung in vier zentrale Bereiche untergliedert, wird zunächst das theoretische Konstrukt sachunterrichtlicher Planungskompetenz in Form eines Kompetenzmodells konzeptualisiert. Auf Grundlage eines performanznahen Kompetenzverständnisses erfolgt die Operationalisierung in Form von Qualitätsstandards, durch die das Können der Probanden aus der schriftlichen Bearbeitung von Vignetten inhaltsanalytisch rekonstruiert werden kann. Ein Kodiermanual sichert die Objektivität und formuliert Regeln für die Vergabe von Punkten, durch die mithilfe des dichotomen Raschmodells die individuellen Kompetenzausprägungen geschätzt werden können. Zur Analyse der psychometrischen Qualität des entwickelten Instrumentes wurde eine Pilotierungsstudie mit 106 Studenten durchgeführt. Ein Vergleich konkurrierender Messmodelle mit Methoden der Item-Response-Theorie weist auf Vorteile einer eindimensionalen Modellierung der fokussierten Kompetenz hin. Die Ergebnisse einer durchgeführten Rasch-Analyse sowie die Betrachtung klassischer Kennwerte belegen zudem die Modellkonformität der entwickelten Qualitätsstandards als Items des Testinstrumentes und zeigen, dass die Messung sachunterrichtlicher Planungskompetenz durch das entwickelte Instrument grundsätzlich objektiv, reliabel und valide realisiert werden kann. Der praktische Nutzen des entwickelten Instrumentes für die angestrebte Wirksamkeitsanalyse des Praxissemesters, Möglichkeiten zur Weiterentwicklung sowie Limitationen werden abschließend zusammenfassend diskutiert. </jats:p>}},

Thus, instructions should be presented in a way that enables fast and errorless information processing. High affordances in visual–spatial transformation (e.g., mental rotation processes) might both impede information processing and decrease execution performance. The aim of this study was to scrutinize the effect of different orientations of visual tactical displays on observation time under self-paced conditions as well as to compare the effects on execution performance to those of externally paced conditions. According to the self-determination theory, self-control over observation time is assumed to increase performance.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>In a mixed-factors design with two factors, 48 participants were instructed to execute a basketball playing pattern, which was presented on a virtual tactic board in one of five different spatial disparities to the players’ on-court perspective.

Electrolyte alkali metal cations have been shown to modify the activity and reaction intermediates, however, the exact mechanism is at question due to unexplained deviations from the cation size trend. Our X-ray absorption spectroelectrochemical results show that bigger cations shift the Ni<jats:sup>2+/(3+δ)+</jats:sup> redox peak and OER activity to lower potentials (however, with typical discrepancies), following the order CsOH &gt; NaOH ≈ KOH &gt; RbOH &gt; LiOH. Here, we find that the OER activity follows the variations in electrolyte pH rather than a specific cation, which accounts for differences both in basicity of the alkali hydroxides and other contributing anomalies. Our density functional theory-derived reactivity descriptors confirm that cations impose negligible effect on the Lewis acidity of Ni, Fe, and O lattice sites, thus strengthening the conclusions of an indirect pH effect.</jats:p>}},

However, the mode structure of pulsed sources and the properties of the detection schemes often require the use of optical filters in order to combine both detection methods in a common experiment. This limits the efficiency and the overall achievable squeezing of the experiment. In our work, we use photon subtraction to implement the distillation of pulsed squeezed states originating from a genuinely spatially and temporally single-mode parametric down-conversion source in non-linear waveguides. Due to the distillation, we witness an improvement of 0.17 dB from an initial squeezing value of −1.648 ± 0.002 dB, while achieving a purity of 0.58, and confirm the non-Gaussianity of the distilled state via the higher-order cumulants. With this, we demonstrate the source’s suitability for scalable hybrid quantum network applications with pulsed quantum light.</jats:p>}},
