Unraveling hydrometeor mixtures in polarimetric radar measurements

Alexis Berne, Jacopo Grazioli, Josué Etienne Gehring, Marco Gabella, Nikola Besic, Urs Martin Germann, Christophe Praz

Radar-based hydrometeor classification typically comes down to determining the dominant type of hydrometeor populating a given radar sampling volume. In this paper we address the subsequent problem of inferring the secondary hydrometeor types present in a ...

Dimensional crossover in the quantum transport behaviour of the natural topological insulator Aleksite

Klaus Kern, Marko Burghard, Pascal Gehring, Alexander Ronald Hoyer, Kristina Vaklinova

Three-dimensional topological insulators comprise topologically protected surface states displaying massless, Dirac-like linear dispersion with spin-momentum locking. Electrical conduction through such surface states has been documented to manifest itself ...

Mixed Dimensionality of Confined Conducting Electrons in the Surface Region of SrTiO3

Thorsten Schmitt, Joël Mesot, Johan Juul Chang, Martin Mansson, Elia Razzoli

Using angle-resolved photoemission spectroscopy, we show that the recently discovered surface state on SrTiO3 consists of nondegenerate t(2g) states with different dimensional characters. While the d(xy) bands have quasi-2D dispersions with weak k(z) depen ...

Numerical modeling of a real-scale nuclear waste engineering barrier experiment

Lyesse Laloui, Bertrand François, Fabrice Dupray

Deep geological repository involving a multi-barrier system constitutes one of the most promising options to isolate high-level radioactive waste from the human environment. The efficiency of Engineered-Barrier Systems (EBS) is highly based on the complex ...

Surface plasmons are able to generate extremely strong and confined optical fields at a deep-subwavelength scale, far beyond the diffraction limit, and now play a central role in nanosciences. A proper combination of plasmonic nanostructures can support Fa ...

In this study, we present the optical properties of nonpolar GaN/(Al,Ga)N single quantum wells (QWs) grown on either a- or m-plane GaN templates for Al contents set below 15%. In order to reduce the density of extended defects, the templates have been proc ...

Crowd animation is a topic of high interest which offers many challenges. One of the most important is the trade-off between rich, realistic behaviors, and computational costs. To this end, much effort has been put into creating variety in character repres ...
