We recently demonstrated that colloidal crystal arrangements of monodisperse droplets or shells of planar-aligned cholesteric liquid crystal exhibit intricate patterns of circularly polarized reflection spots of different colors. The spots appear as a result of photonic cross communication between droplets, hence the patterns reflect the macroscopic arrangement of droplets or shells. Apart from being an interesting optical phenomenon, it offers attractive application opportunities in photonics and beyond, due to the unique characteristics of the patterns. It turns out that the optical quality of shells is much enhanced compared to that of droplets, hence we focus our attention primarily on shells, of varying thickness. Here we analyze and explain the intriguing textures arising when studying planar-aligned short-pitch cholesteric shells in transmission polarizing optical microscopy. In this case, the texture reflects the properties of each individual shell, without any sign of cross communication, yet also this pattern holds some fascinating mysteries. These can only be elucidated by considering all the peculiar optical properties of cholesterics together, as well as the unusual situation given by the spherical shell geometry. [less ▲]

Herein, we study transmit beamforming techniques in an underlay cognitive mode for the coexistence of satellite and terrestrial networks with the satellite forward link as primary and the terrestrial downlink as secondary. Since geostationary satellite terminals have predetermined propagation characteristics so that they always point towards the geostationary satellite, the interference received by the satellite terminals from the terrestrial Base Station (BS) is confined in an angular sector. Based on this a priori knowledge, we propose transmit beamforming techniques at the BS to maximize the Signal to Interference plus Noise Ratio (SINR) towards the desired secondary user and to mitigate the interference towards the primary satellite terminals. Different types of Linearly Constrained Minimum Variance (LCMV) techniques have been proposed for our considered scenario where the exact locations and the number of satellite terminals within a specific angular sector are not known while designing the beamformer. Furthermore, an optimization problem is formulated for maximizing the Secondary User (SU) rate and it is shown that the worst case SU rate depends on the Primary User (PU) distance, PU interference threshold and the angular separation of the desired SU from the region of interest.

This Article discusses the reality of executive rule-making procedures with trans-territorial effect, with other words, the creation of non-legislative rules which have an effect outside the territorial limits of the jurisdiction of origin. It maps the phenomenon, discusses some of its central challenges for the realization of general principles of law and considers possible legal approaches addressing these. One of the most important issues thereby is to find workable solutions in the context of the pluralism of sources of law – national, supranational and international. [less ▲]

Against the backdrop of the ongoing crisis-led migration from Southern to Northwestern Europe, the present paper reports on a case study of two families who have recently migrated from Greece to Luxembourg. Luxembourg has a trilingual education system and many pupils of migrant background face difficulties on this account. Drawing on the framework of Family Language Policy, this paper explores the language ideologies and management strategies of two families as well as factors influencing their policies. This qualitative study was based on interviews, observations, and videos recorded by one of the families. The findings show that the families have contrasting language ideologies and management strategies that are informed by their differing transnational experiences, competences and worldviews. This study can contribute to a better understanding of the ways in which migrant families use their language resources in their new country. [less ▲]

Le présent article vise à déterminer si et dans quelle mesure les règles et pratiques juridiques actuelles de l’Union européenne en matière de transparence et de participation encouragent les principes démocratiques récemment ancrés dans le traité sur l’Union européenne. Il se concentre essentiellement sur la façon dont les principes de transparence et de participation ont été formulés et surtout mis en œuvre dans la pratique, afin d’examiner leur éventuelle signification démocratique. Il pose la question de savoir s’il existe vraiment un panorama des principes démocratiques de l’administration européenne. [less ▲]
