Im vorliegenden Beitrag wird auf die Befragung der ErzieherInnen fokussiert, die mittels halbstandardisierter Fragebögen durchgeführt wurde. Untersucht wurde, wie sich der sprachlich-kulturelle Hintergrund der Kinder für das Kommunikationsverhalten der ErzieherInnen mit den Kindern in pädagogischer Anschlusskommunikation und in Gesprächen mit den Eltern der Kinder auswirkt. Hier wurde auch eine intersektionale Perspektive eingenommen und parallel zur Herkunftskultur auch das biologische Geschlecht der Kinder in die Auswertung einbezogen. Es stellte sich heraus, dass die Kommunikation sowohl mit den Kindern als auch mit den Eltern in Abhängigkeit der Herkunftskultur der Kinder und auch ihres Geschlechtes erfolgt. Pädagogisch ist zu fragen, inwiefern es den pädagogischen Fachkräften gelingt, benachteiligende Ausgangslagen auch tatsächlich auszugleichen und Partizipation im Sinne von Inklusion zu ermöglichen. Ausgehend von diesen Ergebnissen wird in diesem Beitrag die Bedeutung und Relevanz der Überschneidungen und Interdependenzen von Ungleichheitsdimensionen für eine inklusionsorientierte Qualifikation pädagogischer Fachkräfte in institutionell-frühkindlichen Medienbildungskontexten diskutiert. Konkret richtet sich der Blick auf die sprachlich-kulturelle Ein- und Vielfalt in den frühkindlichen Einrichtungen sowie die Wahrnehmungen und Einschätzungen der pädagogischen Fachkräfte, die sie in Hinblick auf die Kooperationswilligkeit der Eltern, die Anschlusskommunikation mit den Kindern und schließlich die medialen Fähig- und Fertigkeiten der Kinder äußern."}],"type":"journal_article","citation":{"ieee":"H.

Our approach complements and extends recent results that were based on Chebyshev's integral inequality \\cite{BA19}. The method developed here correlates arbitrary phase-space functions at arbitrary points in phase space, including multimode scenarios and higher-order correlations. Furthermore, our approach provides necessary and sufficient nonclassicality criteria, applies to phase-space functions beyond s-parametrized ones, and is accessible in experiments. To demonstrate the power of our technique, the quantum characteristics of discrete- and continuous-variable, single- and multimode, as well as pure and mixed states are certified only employing second-order correlations and Husimi functions, which always resemble a classical probability distribution. Moreover, nonlinear generalizations of our approach are studied. Therefore, a versatile and broadly applicable framework is devised to uncover quantum properties in terms of matrices of phase-space distributions."}],"user_id":"16199","title":"Probing nonclassicality with matrices of phase-space distributions","language":[{"iso":"eng"}],"citation":{"ama":"Bohmann M, Agudelo E, Sperling J.

This holds in particular for the energy and the spatial localization of the highest occupied and lowest unoccupied molecular orbitals. In addition to a substantial gap narrowing, a pronounced separation of photoexcited electrons and holes is predicted in some instances.

In inhomogeneous ensembles a macroscopic optical polarization decays rapidly due to dephasing, which, however, is reversible in photon echoes carrying complete information about the coherent ensemble dynamics. Control of the echo emission time is mandatory for applications. Here, we propose a concept to reach this goal. In a two-pulse photon echo sequence, we apply an additional resonant control pulse with multiple of 2π area. Depending on its arrival time, the control slows down dephasing or rephasing of the exciton ensemble during its action. We demonstrate for self-assembled (In,Ga)As quantum dots that the photon echo emission time can be retarded or advanced by up to 5 ps relative to its nominal appearance time without control. This versatile protocol may be used to obtain significantly longer temporal shifts for suitably tailored control pulses."}],"volume":3,"status":"public","date_created":"2020-12-16T14:30:57Z","author":[{"last_name":"Kosarev","full_name":"Kosarev, Alexander N.","first_name":"Alexander N."},{"last_name":"Rose","id":"55958","first_name":"Hendrik","orcid":"0000-0002-3079-5428","full_name":"Rose, Hendrik"},{"last_name":"Poltavtsev","full_name":"Poltavtsev, Sergey V.","first_name":"Sergey V."},{"id":"138","last_name":"Reichelt","full_name":"Reichelt, Matthias","first_name":"Matthias"},{"full_name":"Schneider, Christian","first_name":"Christian","last_name":"Schneider"},{"first_name":"Martin","full_name":"Kamp, Martin","last_name":"Kamp"},{"last_name":"Höfling","first_name":"Sven","full_name":"Höfling, Sven"},{"last_name":"Bayer","first_name":"Manfred","full_name":"Bayer, Manfred"},{"first_name":"Torsten","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier","id":"344"},{"full_name":"Akimov, Ilya A.","first_name":"Ilya A.","last_name":"Akimov"}],"publication":"Communications Physics","article_number":"228","issue":"1","_id":"20773","intvolume":" 3","type":"journal_article","citation":{"mla":"Kosarev, Alexander N., et al. “Accurate Photon Echo Timing by Optical Freezing of Exciton Dephasing and Rephasing in Quantum Dots.” Communications Physics, vol. 3, no. 1, 228, 2020, doi:10.1038/s42005-020-00491-2.","bibtex":"@article{Kosarev_Rose_Poltavtsev_Reichelt_Schneider_Kamp_Höfling_Bayer_Meier_Akimov_2020, title={Accurate photon echo timing by optical freezing of exciton dephasing and rephasing in quantum dots}, volume={3}, DOI={10.1038/s42005-020-00491-2}, number={1228}, journal={Communications Physics}, author={Kosarev, Alexander N. and Rose, Hendrik and Poltavtsev, Sergey V. and Reichelt, Matthias and Schneider, Christian and Kamp, Martin and Höfling, Sven and Bayer, Manfred and Meier, Torsten and Akimov, Ilya A.}, year={2020} }","ama":"Kosarev AN, Rose H, Poltavtsev SV, et al.

With their additional degree of freedom, the vorticity, they have been widely investigated in many physical systems and different materials for fundamental interest and for applications in data storage and information processing. Vortices have also been observed in non-equilibrium exciton-polariton condensates in planar semiconductor microcavities. There they appear spontaneously or can be created and pinned in space using ring-shaped optical excitation profiles. However, using the vortex state for information processing not only requires creation of a vortex but also efficient control over the vortex after its creation. Here we demonstrate a simple approach to control and switch a localized polariton vortex between opposite states. In our scheme, both the optical control of vorticity and its detection through the orbital angular momentum of the emitted light are implemented in a robust and practical manner.","lang":"eng"}],"user_id":"16199"},{"doi":"10.1117/12.2545924","date_updated":"2023-04-21T11:22:44Z","language":[{"iso":"eng"}],"series_title":"SPIE Proceedings","title":"k.p-based multiband simulations of non-degenerate two-photon absorption in bulk GaAs","publication_status":"published","publication_identifier":{"isbn":["9781510633193","9781510633209"]},"editor":[{"last_name":"Betz","first_name":"Markus","full_name":"Betz, Markus"},{"full_name":"Elezzabi, Abdulhakem Y.","first_name":"Abdulhakem Y.","last_name":"Elezzabi"}],"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"TRR 142","_id":"53"},{"name":"TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - Subproject A7","_id":"64"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"intvolume":" 11278","_id":"20770","page":"112780S","type":"conference","year":"2020","citation":{"mla":"Hannes, Wolf-Rüdiger, and Torsten Meier. “K.p-Based Multiband Simulations of Non-Degenerate Two-Photon Absorption in Bulk GaAs.” Ultrafast Phenomena and Nanophotonics XXIV, edited by Markus Betz and Abdulhakem Y.

While the cooling capacity has long been anchored in various test procedures of consumer organizations, the temperature rise time, which has only been tested on freezers so far, will be a decisive factor in the future. Moreover, the need for so-called \"smart appliances\" that may balance power consumption is increasing since such devices may compensate the volatility of renewable energies and thus stabilize the power grid. Against this background, eight commercial household refrigerators and refrigerator-freezers are equipped with polymer-bound phase change materials (PCM) and their performance is determined under the new stan- dard test conditions. The results show that the introduction of PCM increases the cooling capacity by up to 33 % and also increases the temperature rise time by up to 145 %, without affecting power consump- tion, as compared to the unmodified refrigeration appliances."}],"user_id":"7828","citation":{"short":"G.

Past studies provide basic evidence for increasing electricity consumption of cooling appliances with ageing but fail to investigate the associated technical wear. Concentrating on the degradation of the thermal insulation, we first determined the ageing process of sealed samples of polyurethane rigid foam by investigating changes in cell gas composition and thermal conductivity over time. Simultaneously, the main challenge was to develop an approach that investigates the age-related efficiency loss of the insulation without its destruction. This testing procedure is referred to as the Bonn method. The non-destructive Bonn method was applied to varying refrigerator models in a series of successive experiments to evaluate the insulation degradation over time. Subsequently, the physical relationship between the test value of the Bonn method and the heat transfer through the multi-layered compartment walls of domestic refrigeration appliances was established, ultimately characterising the degrading insulation in terms of increasing heat transfer. Our results give substantiated evidence that the efficiency loss of cooling appliances is greatly influenced by insulation degradation over time. The ageing of sealed samples of polyurethane rigid foam indicates a large initial increase of thermal conductivity by 15% within the first year, corresponding to a change in cell gas composition. These results are in line with those of the Bonn method, emphasising an increasing heat flow through the multi-layered compartment walls of domestic refrigerators with ageing. Therewith, the present study is of significance to a wide range of stakeholders and forms the basis for future research."}],"user_id":"7828"},{"series_title":"Journal of Advanced Joining Processes","language":[{"iso":"eng"}],"date_updated":"2023-04-28T09:19:41Z","doi":"10.1016/j.jajp.2020.100023","department":[{"_id":"157"}],"publication_status":"published","editor":[{"last_name":"Kuball","full_name":"Kuball, Clara-Maria","first_name":"Clara-Maria"},{"first_name":"R","full_name":"Jung, R","last_name":"Jung"},{"id":"38131","last_name":"Uhe","full_name":"Uhe, Benedikt","first_name":"Benedikt"},{"last_name":"Meschut","id":"32056","first_name":"Gerson","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson"},{"full_name":"Merklein, Marion","first_name":"Marion","last_name":"Merklein"}],"title":"Influence of the process temperature on the forming behaviour and the friction during bulk forming of high nitrogen steel","year":"2020","type":"conference_editor","citation":{"bibtex":"@book{Kuball_Jung_Uhe_Meschut_Merklein_2020, series={Journal of Advanced Joining Processes}, title={Influence of the process temperature on the forming behaviour and the friction during bulk forming of high nitrogen steel}, volume={1}, DOI={10.1016/j.jajp.2020.100023}, number={100023}, year={2020}, collection={Journal of Advanced Joining Processes} }","mla":"Kuball, Clara-Maria, et al., editors.

These techniques allow for the joining of dissimilar materials and thus enable multi-material design, while thermic joining methods reach their limits. Semi-tubular self-piercing riveting is an important mechanical joining technology. The rivet production, however, is costly and time-consuming, as the process consists of several process steps including the heat treatment and coating of the rivets in order to achieve an adequate strength and corrosion resistance. The use of high nitrogen steel as rivet material leads to the possibility of reducing process steps and hence increasing the efficiency of the process. However, the high tool loads being expected due to the high strain hardening of the material are a major challenge during the rivet production. Thus, there is a need for appropriate forming strategies, such as the manufacturing of the rivets at elevated temperatures. Prior investigations led to the conclusion that forming already at 200 °C results in a distinct reduction of the yield strength. To create a deeper understanding of the forming behaviour of high nitrogen steel at elevated temperatures, compression tests were conducted in a temperature range between room temperature and 200 °C. The determined true stress – true strain curves are the basis for the further process and tool design of the rivet production. Another key factor for the rivet manufacturing at elevated temperatures is the influence of the process temperature on the tribological conditions. For this reason, ring compression tests at room temperature and 200 °C are carried out. The friction factors are determined on the basis of calibration curves resulting from the numerical analysis of the ring compression process. The investigations indicate that the friction factor at 200 °C is significantly higher compared to room temperature. This essential fact has to be taken into account for the process and tool design for the rivet production using high nitrogen steel."}],"user_id":"38131"},{"user_id":"38131","article_type":"original","abstract":[{"text":"As a result of lightweight design, increased use is being made of high-strength steel and aluminium in car bodies. Self-piercing riveting is an established technique for joining these materials. The dissimilar properties of the two materials have led to a number of different rivet geometries in the past. Each rivet geometry fulfils the requirements of the materials within a limited range. In the present investigation, an improved rivet geometry is developed, which permits the reliable joining of two material combinations that could only be joined by two different rivet geometries up until now. Material combination 1 consists of high-strength steel on both sides, while material combination 2 comprises aluminium on the punch side and high-strength steel on the die side. The material flow and the stress and strain conditions prevailing during the joining process are analysed by means of numerical simulation. The rivet geometry is then improved step-by-step on the basis of this analysis. Finally, the improved rivet geometry is manufactured and the findings of the investigation are verified in experimental joining tests.","lang":"eng"}],"status":"public","date_created":"2020-10-12T08:14:13Z","volume":14,"quality_controlled":"1","author":[{"full_name":"Uhe, Benedikt","first_name":"Benedikt","id":"38131","last_name":"Uhe"},{"first_name":"Clara-Maria","full_name":"Kuball, Clara-Maria","last_name":"Kuball"},{"full_name":"Merklein, Marion","first_name":"Marion","last_name":"Merklein"},{"first_name":"Gerson","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","last_name":"Meschut","id":"32056"}],"publication":"Production Engineering","keyword":["Self-piercing riveting","Joining technology","Rivet geometry","Multi-material design","High-strength steel","Aluminium"],"intvolume":" 14","_id":"19973","year":"2020","type":"journal_article","citation":{"ieee":"B.

In the present study different dimensionless joining displacements are accounted for. The results show that high short-term tensile strength does not directly transfer to high long-term tensile strength. The morphology of the weld seam in the joined samples is examined by means of transmitted and reflected light microscopy. For the dimensionless joining displacements of 0.75 and 0.95, stretched spherulites are obtained. X-Ray diffraction can be used as a tool for qualitative and quantitative analysis and eventually for differentiation of samples of various joining displacements."}]},{"citation":{"bibtex":"@inproceedings{Schöppner_Wübbeke_Geißler_Schmidt_Maginer_Wu_Niendorf_Jakob_Heim_2020, place={Marina Bay (Singapore)}, title={Investigation of residual stresses of hot plate welding}, booktitle={73rd Annual Assembly of the International Institute of Welding (IIW)}, publisher={Springer-Verlag}, author={Schöppner, Volker and Wübbeke, Andrea and Geißler, B. and Schmidt, M. and Maginer, A. and Wu, T. and Niendorf, T. and Jakob, F. and Heim, H.}, year={2020} }","mla":"Schöppner, Volker, et al. “Investigation of Residual Stresses of Hot Plate Welding.” 73rd Annual Assembly of the International Institute of Welding (IIW), Springer-Verlag, 2020.","chicago":"Schöppner, Volker, Andrea Wübbeke, B.
