Wie die meisten EU-Staaten, setzt auch Luxemburg mit dem quantitativen wie qualitativen Ausbau von Kindertageseinrichtungen in der frühen Kindheit auf so genannte kindzentrierte sozialinvestive Politikstrategien , in deren Zuge eine flächendeckende, hochwertige und frühe Kindertagesbetreuung als besonders „effektives Mittel im Krieg gegen die Vererbung sozialer Nachteile “ angesehen wird. Den vorschulischen Kindertageseinrichtungen kommt neben ihrer arbeits- und sozialpolitischen Funktion dabei vor allem die Aufgabe zu, gleichsam präventiv-kompensatorisch dafür zu sorgen, dass alle Kinder gleich welcher Herkunft durch frühe Bildungsangebote gute Startbedingungen für ihre schulische Bildungslaufbahn erhalten. Vor dem Hintergrund der bereits für das Schulsystem dargelegten Spannung zwischen dem Abbau sozialer Ungleichheiten und deren Reproduktion durch ihre Übersetzung in Bildungsungleichheiten, drängt sich jedoch die Frage auf, ob und wenn ja wie genau Kindertageseinrichtungen in der Lage sind diese hohen Erwartungen zu erfüllen. Gelingt es Kindertageseinrichtungen bisher ungleiche soziale Bildungsbedingungen von jungen Kindern auszugleichen oder lassen sich vielmehr Prozesse einer ‚Verfrühung von Bildungsungleichheiten’ beobachten? Diese Fragen stehen im Fokus des Beitrags, der den internationalen Stand der Forschung zum Zusammenhang von sozialer Ungleichheit und Kindertagesbetreuung nachzeichnet. An ausgewählten Forschungsergebnissen werden dabei insbesondere die sich bisher abzeichnenden Mechanismen der Reproduktion sozialer Ungleichheiten in der Kindertagesbetreuung aufgezeigt, die Ansatzpunkte für eine ungleichheitssensible Qualitätsentwicklung liefern können.

2020 was a challenging year for everyone that will stay in our memory. The pandemic disrupted our economies, societies, and all our best laid-out plans. However, COVID-19 also taught us several lessons for the future, in particular the (real) necessity to adapt, to be nimble and to expect the unexpected while supporting cutting-edge excellence in science with the best performing and most flexible tools to unleash research potential. One thing is certain - the strategic developments for accelerated digitalisation and the role that HPC will play to ensure a smarter and more connected University will be in focus in 2021 and the years to come. 2020 was thus a very fruitful and productive year for the ULHPC team which has seen unprecedented changes and challenges.

Based on Brown’s static equations of micromagnetics, the uniaxial polarization of the scattered neutron beam of a bulk magnetic material is computed. The approach considers a Hamiltonian that takes into account the isotropic exchange interaction, the antisymmetric Dzyaloshinskii–Moriya interaction, magnetic anisotropy, the dipole–dipole interaction, as well as the effect of an applied magnetic field. In the high-field limit, the solutions for the magnetization Fourier components are used to obtain closed-form results for the spinpolarized SANS (small-angle neutron scattering) cross sections and the ensuing polarization. The theoretical expressions are compared with experimental data on a soft magnetic nanocrystalline alloy. The micromagnetic SANS theory provides a general framework for polarized real-space neutron methods, and it may open up a new avenue for magnetic neutron data analysis on magnetic microstructures.

Unidirectional P-body transport during the yeast cell cycle.

P-bodies belong to a large family of RNA granules that are associated with post-transcriptional gene regulation, conserved from yeast to mammals, and influence biological processes ranging from germ cell development to neuronal plasticity. RNA granules can also transport RNAs to specific locations. Germ granules transport maternal RNAs to the embryo, and neuronal granules transport RNAs long distances to the synaptic dendrites. Here we combine microfluidic-based fluorescent microscopy of single cells and automated image analysis to follow p-body dynamics during cell division in yeast. Our results demonstrate that these highly dynamic granules undergo a unidirectional transport from the mother to the daughter cell during mitosis as well as a constrained "hovering" near the bud site half an hour before the bud is observable. Both behaviors are dependent on the Myo4p/She2p RNA transport machinery. Furthermore, single cell analysis of cell size suggests that PBs play an important role in daughter cell growth under nutrient limiting conditions. [less ▲]

Unified Description of the Optical Phonon Modes in N-Layer MoTe2

N-layer transition metal dichalcogenides provide a unique platform to investigate the evolution of the physical properties between the bulk (three-dimensional) and monolayer (quasi-two-dimensional) limits. Here, using high-resolution micro-Raman spectroscopy, we report a unified experimental description of the Γ-point optical phonons in N-layer 2H-molybdenum ditelluride (MoTe2). We observe series of N-dependent low-frequency interlayer shear and breathing modes (below 40 cm–1, denoted LSM and LBM) and well-defined Davydov splittings of the mid-frequency modes (in the range 100–200 cm–1, denoted iX and oX), which solely involve displacements of the chalcogen atoms. In contrast, the high-frequency modes (in the range 200–300 cm–1, denoted iMX and oMX), arising from displacements of both the metal and chalcogen atoms, exhibit considerably reduced splittings. The manifold of phonon modes associated with the in-plane and out-of-plane displacements are quantitatively described by a force constant model, including interactions up to the second nearest neighbor and surface effects as fitting parameters. The splittings for the iX and oX modes observed in N-layer crystals are directly correlated to the corresponding bulk Davydov splittings between the E2u/E1g and B1u/A1g modes, respectively, and provide a measurement of the frequencies of the bulk silent E2u and B1u optical phonon modes. Our analysis could readily be generalized to other layered crystals [less ▲]

We present a combination of techniques to improve the convergence and conditioning properties of partition of unity (PU) enriched finite element methods. By applying these techniques to different types of enrichment functions, namely polynomial, discontinuous and singular, higher order convergence rates can be obtained while keeping condition number growth rates similar to the ones corresponding to standard finite elements.
