Spinning test-body orbiting around Schwarzschild black hole: circular dynamics and gravitational-wave fluxes
<p>We release gravitational wave fluxes at null-infinity from a spinning test-body in circular equatorial orbits around a Schwarzschild black hole. Four different prescriptions are used for the dynamics: the Mathisson-Papapetrou formalism under the Tulczyjew (TUL) spin-supplementary-condition (SSC), the Pirani (PIR) SSC and the Ohashi-Kyrian-Semerak (OKS) SSC, and the spinning particle limit of the effective-one-body Hamiltonian (HAM) of [Phys.~Rev.~D.90,~044018(2014)]. For more details see xxxx .</p> <p>The multipolar fluxes are given for l=2,3 m=1,2,3 at the Boyer-Lindquist radii</p> <p> r = 4 5 6 7 8 10 12 15 20 30 ,</p> <p>in cases they were not computed the data contains a "42". Note that the fluxes in these data files are assumed to contain both the +m and -m contributions, since they are identical for equatorial orbits and aligned spins. <br /> Additionally, the data files contain the key numbers describing the circular dynamics (see paper).</p> <p>Units <span class="math-tex"><em>c</em>=<em>G</em>=1.</span></p>
3D Printed Antennas for mm-Wave Sensing Applicatins: Dataset
<p>This is the dataset related to the paper "3D Printed Antenass for mm-Wave Sensing Applications":</p> <p>This paper presents three low cost 3D printed antenna concepts for integration with a miniature mm-wave platform. The proposed solutions are optimized to operate in mm-wave ISM band (122GHz-123GHz). Different, inexpensive, detachable antennas can be used with the same platform for various RF sensing applications such as food safety, health and industrial.</p>
Spatial impulse wave
<p>ENGLISH<br> <br> Landslides and avalanches in natural lakes and reservoirs may generate so-called impulse waves. The run-up effects of these waves at the shore are similar to those of tsunamis. Hydraulic experiments in the laboratory help to estimate key wave characteristics, including the wave height and celerity. The picture presents two images of an experiment in the wave basin of the Laboratory of Hydraulics, Hydrology and Glaciology (VAW) at ETH Zurich. At the upper left, the moment shortly after the slide has hit the water surface is shown. The slide transfers its kinetic energy to the water and generates a wave. In the section on the lower right, the waves have propagated circularly from the impact location. The water is dyed white so that a grid can be projected onto the surface. During the experiment, this raster projection is simultaneously filmed by several cameras and the analysis of the image data allows for an accurate determination of the wave height decay.<br> <br> GERMAN<br> <br> Erdrutsche und Lawinen in natürliche Seen oder Stauseen können sogenannte Impulswellen auslösen. Die Auswirkungen beim Auflaufen dieser Wellen am Ufer sind mit denen von Tsunamis vergleichbar. Hydraulische Experimente im Labor helfen dabei, massgebliche Welleneigenschaften, wie beispielsweise die Höhe oder die Ausbreitungsgeschwindigkeit, abzuschätzen. Das Bild stellt zwei Aufnahmen eines Experiments im Wellenbecken der Versuchsanstalt für Wasserbau, Hydrologie und Glaziologie der ETH Zürich zu unterschiedlichen Zeitpunkten dar. Oben links ist der Moment kurz nach dem Auftreffen des Rutsches auf die Wasseroberfläche zu sehen. Der Rutsch überträgt dabei seine Bewegungsenergie auf das Wasser und erzeugt eine Welle. Im Ausschnitt unten rechts haben sich die Wellen kreisförmig von der Eintauchstelle weg ausgebreitet. Das Wasser ist weiss eingefärbt, damit ein Raster auf die Oberfläche projiziert werden kann. Diese Rasterprojektion wird während des Experiments gleichzeitig von mehreren Kameras gefilmt und die Auswertung der Bilddaten ermöglicht eine genaue Bestimmung der Wellenhöhenabnahme.</p>

Photon wave function and the electromagnetic vacuum
<p>The association of the density of states theory to the vector potential quantization of the electromagnetic field leads naturally to the definition of the photon quantization volume, ascribing an intrinsic physical geometrical property to a single photon. Photons are not point particles and constitute a particular case in particles standard model. Based upon the vector potential with quantized amplitude, we define a photon wave function representing an amplitude probability for the photon localization normalized with respect to the photon quantization volume. In addition, the established photon wave function satisfies Maxwell's propagation equation and Schrödinger's equation with the relativistic massless particle Hamiltonian as well as a Schrödinger-like equation for the vector potential. </p><p>The electromagnetic vacuum derives straightforward from the photon vector potential function and has both classical and quantum representations. It permits to remedy to the zero-point energy shortcomings and singularities in quantum electrodynamics. Finally, the photon wave function is naturally related to the electromagnetic vacuum states putting the basis for understanding entanglement. </p>
