Der Band ist das „Ergebnis eines Dialogs“ (S. 9) von Vertreter/innen der Sozialpädagogik und der Kindheitspädagogik. Er markiert damit einen Wendepunkt im Verhältnis der beiden Bereiche bzw. Teildisziplinen und ihrer entsprechenden Kommissionen innerhalb der DGfE, die Ende der 1990er Jahre unter dem Dach der „Sektion Sozialpädagogik“ vereint wurden und dort eher nebeneinander agierten. Den neuen Orientierungen des vorangegangenen Jahrzehnts Rechnung tragend, veranstalteten die beiden Kommissionen im Sommer 2011 in Erkner bei Berlin eine gemeinsame Tagung, aus der die Beiträge zum vorliegenden Band hervorgegangen sind und im Rahmen derer die Aufnahme der „Pädagogik der frühen Kindheit“ in den Sektionstitel beschlossen wurde.

We find that the octadecylsilane-conjugated gold NPs stabilize both the enantiotropic nematic and the monotropic smectic-A phases of the LC host with a maximum stabilization of 2 ° C for the nematic and 3.5 ° C for the smectic-A phases for the mixture containing 1 wt% of the silanized particles. The same mixture shows the lowest values for the Fréedericksz transition threshold voltage and the highest value for the dielectric anisotropy. Generally, all NP-containing mixtures, except mixtures with NP concentrations exceeding 5 wt%, reduce the threshold voltage, increase the dielectric anisotropy and reduce both rise and decay time; the latter particularly at temperatures at least 10 ° C below the isotropic–nematic phase transition on cooling. }}, author = {{Mirzaei, Javad and Urbanski, Martin and Kitzerow, Heinz-Siegfried and Hegmann, Torsten}}, issn = {{1364-503X}}, journal = {{Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences}}, keywords = {{General Physics and Astronomy, General Engineering, General Mathematics}}, number = {{1988}}, publisher = {{The Royal Society}}, title = {{{Hydrophobic gold nanoparticles via silane conjugation: chemically and thermally robust nanoparticles as dopants for nematic liquid crystals}}}, doi = {{10.1098/rsta.2012.0256}}, volume = {{371}}, year = {{2013}}, } @article{39719, author = {{Vollbrecht, Joachim and Kasdorf, Olga and Quiring, Viktor and Suche, Hubertus and Bock, Harald and Kitzerow, Heinz-Siegfried}}, issn = {{0003-6951}}, journal = {{Applied Physics Letters}}, keywords = {{Physics and Astronomy (miscellaneous)}}, number = {{4}}, publisher = {{AIP Publishing}}, title = {{{Microresonator-enhanced electroluminescence of an organic light emitting diode based on a columnar liquid crystal}}}, doi = {{10.1063/1.4816425}}, volume = {{103}}, year = {{2013}}, } @article{37672, abstract = {{AbstractLet ${F}_{BC} (\lambda , k; t)$ be the Heckman–Opdam hypergeometric function of type BC with multiplicities $k= ({k}_{1} , {k}_{2} , {k}_{3} )$ and weighted half-sum $\rho (k)$ of positive roots.

Multiple-input multiple-output (MIMO) structured channels arise when symbol extensions -either in time or frequency- are employed jointly with the spatial dimension in the design of the precoders. In this case, the rank constraint in the direct channels must explicitly be taken into account into the optimization problem to ensure that there is no degrees-of-freedom (DoF) loss. To this end, we propose an algorithm that minimizes the interference leakage while ensuring that the direct links are full rank and the transmitters satisfy a power constraint. The algorithm is based upon an alternating optimization procedure, which solves a generalized eigenvalue problem at each step. We show through simulations the advantages of the proposed algorithm in several scenarios that use symbols extensions or improper (a.k.a. asymmetric) signalling.}}, author = {{Lameiro, Christian and Santamaría, Ignacio}}, booktitle = {{Proc.

In this paper, we study the 4-user SISO interference channel and provide inner and outer bounds for the total number of DoF achievable for this channel. We prove that at least 4/3 DoF are achievable for the 4-user channel using also linear interference alignment techniques and improper signaling. A simple converse proof shows that no more than 8/5 DoF are achievable for this scheme.
