Längsschnittstudien, die das bildungswissenschaftliche Wissen als Teil der professionellen Kompetenz angehender Lehrkräfte über mehr als zwei Messzeitpunkte erfassen und den Einfluss individueller Eingangsvoraussetzungen auf die Wissensentwicklung untersuchen, stellen nach wie vor ein Forschungsdesiderat dar. Bisherige Studien liefern erste Hinweise darauf, dass individuelle Eingangsvoraussetzungen wie die Abiturnote, pädagogische Vorerfahrungen und Berufswahlmotive im Zusammenhang mit der Wissensentwicklung stehen und günstige Eingangsvoraussetzungen den Entwicklungsverlauf fördern können. Bislang ist unklar, wie sich das Wissen über den gesamten Studienverlauf in den Bachelor-/Master-Strukturen entwickelt. Des Weiteren ist auch unklar, inwieweit bestimmte Eingangsvoraussetzungen langfristige Entwicklungsverläufe erklären können. In der vorliegenden Studie wurden die Daten von 276 Studierenden, dessen Wissen zu fünf Messzeitpunkten erhoben wurde, mit Hilfe latenter Wachstumskurvenmodelle ausgewertet. Die Ergebnisse bestätigten einen Zuwachs des bildungswissenschaftlichen Wissens über den gesamten Studienverlauf. Den größten Wissenszuwachs erfuhren die Studierenden in den ersten zwei Semestern ihres Bachelorstudiums und beim Übergang in das Masterstudium. Des Weiteren konnte der Einfluss von individuellen kognitiven und motivationalen Eingangsvoraussetzungen auf den Leistungszuwachs bestätigt werden. So zeigte sich, dass Studierende, die eine bessere Abiturnote aufwiesen und bereits über eine unterrichtsnahe pädagogische Vorerfahrung verfügten, höhere Wissenszuwächse im Vergleich zu ihren Kommilitoninnen und Kommilitonen erfuhren, die einen schlechteren Abiturnotendurchschnitt hatten. Ebenfalls begünstigte das Motiv „mit Kindern und Jugendlichen arbeiten zu wollen“ die Wissensentwicklung. Die Ergebnisse können insbesondere für die Beratung genutzt werden, um die Motivlagen von Studierenden zu erfassen und sie dafür sensibel zu machen, welche Motivkonstellationen für einen erfolgreichen Studienverlauf günstig erscheinen. </jats:p>","lang":"ger"}],"publication":"Zeitschrift für Pädagogische Psychologie","type":"journal_article","doi":"10.1024/1010-0652/a000288","title":"Kompetenzentwicklung im bildungswissenschaftlichen Studium: Der Einfluss                individueller Voraussetzungen auf die Entwicklung des bildungswissenschaftlichen                Wissens angehender Lehrkräfte","date_created":"2021-09-21T09:30:42Z","author":[{"first_name":"Christina","last_name":"Watson","full_name":"Watson, Christina"},{"last_name":"Stender","orcid":"https://orcid.org/0000-0002-6756-9440","full_name":"Stender, Jana","id":"28542","first_name":"Jana"},{"last_name":"Schaper","full_name":"Schaper, Niclas","first_name":"Niclas"}],"date_updated":"2023-01-09T17:21:37Z","page":"1-16","citation":{"ama":"Watson C, Stender J, Schaper N.

The replicated patterns can, however, only be as precise as their templates. Thus, the investigation of the morphology of polymer domains is of great importance. Commonly used analytical techniques (neutron scattering, scanning force microscopy) either lack spatial information or nanoscale resolution. Using advanced analytical (scanning) transmission electron microscopy ((S)TEM), we provide real space information on polymer domain morphology and interfaces between polystyrene (PS) and polymethylmethacrylate (PMMA) in cylinder- and lamellae-forming BCPs at highest resolution. This allows us to correlate the internal structure of polymer domains with line edge roughnesses, interface widths and domain sizes. STEM is employed for high-resolution imaging, electron energy loss spectroscopy and energy filtered TEM (EFTEM) spectroscopic imaging for material identification and EFTEM thickness mapping for visualisation of material densities at defects. The volume fraction of non-phase separated polymer species can be analysed by EFTEM. These methods give new insights into the morphology of polymer domains the exact knowledge of which will allow to improve pattern quality for nanolithography.</jats:p>","lang":"eng"}],"publication":"Nanomaterials","doi":"10.3390/nano10010141","author":[{"full_name":"Bürger, Julius","id":"46952","last_name":"Bürger","first_name":"Julius"},{"last_name":"Kunnathully","full_name":"Kunnathully, Vinay","first_name":"Vinay"},{"first_name":"Daniel","last_name":"Kool","id":"44586","full_name":"Kool, Daniel"},{"first_name":"Jörg","id":"20797","full_name":"Lindner, Jörg","last_name":"Lindner"},{"first_name":"Katharina","last_name":"Brassat","id":"11305","full_name":"Brassat, Katharina"}],"volume":10,"date_updated":"2023-01-10T12:11:57Z","citation":{"apa":"Bürger, J., Kunnathully, V., Kool, D., Lindner, J., &#38; Brassat, K.

The main limitation on ENOB in purely electrical ADCs lies in the relatively high jitter of oscillators, in the order of a few tens of fs for state-of-the-art components. When compared to the extremely low jitter obtained with best-in-class Ti:sapphire mode-locked lasers (MLL), in the attosecond range, it is apparent that a mixed electrical-optical architecture could significantly improve the converters' ENOB. We model and analyze the ENOB limitations arising from optical sources in optically enabled, spectrally sliced ADCs, after discussing the system architecture and implementation details. The phase noise of the optical carrier, serving for electro-optic signal transduction, is shown not to propagate to the reconstructed digitized signal and therefore not to represent a fundamental limit. The optical phase noise of the MLL used to generate reference tones for individual slices also does not fundamentally impact the converted signal, so long as it remains correlated among all the comb lines. On the other hand, the timing jitter of the MLL, as also reflected in its RF linewidth, is fundamentally limiting the ADC performance, since it is directly mapped as jitter to the converted signal. The hybrid nature of a photonically enabled, spectrally sliced ADC implies the utilization of a number of reduced bandwidth electrical ADCs to convert parallel slices, resulting in the propagation of jitter from the electrical oscillator supplying their clock. Due to the reduced sampling rate of the electrical ADCs, as compared to the overall system, the overall noise performance of the presented architecture is substantially improved with respect to a fully electrical ADC.","lang":"eng"}],"status":"public","type":"conference","publication":"21.

In both data converter architectures, a mode-locked laser is assumed to provide an optical comb whose lines are used to either synthesize or analyze individual spectral slices. While the optical phase noise of the central MLL line as well as of other optical carriers used in the analyzed system architectures have a minor impact on the system performance, the RF phase noise of the MLL fundamentally limits it. In particular, the corresponding jitter of the MLL pulse train is transferred almost one-to-one to the system-level timing jitter of the data converters. While MLL phase noise can in principle be tracked and removed by electronic signal processing, this results in electric oscillator phase noise replacing the MLL jitter and is not conducive in systems leveraging the ultra-low jitter of low-noise mode-locked lasers. Precise analytical models are derived and validated by detailed numerical simulations.","lang":"eng"}],"type":"journal_article","publication":"Opt.

The concept of the OEPLL is presented and it's measured phase noise is compared to the phase noise of a laboratory-grade electronic frequency synthesizer. The measured phase noise spectra of both synthesizers at 10 GHz are then used to model LO phase noise at 320 GHz. Based on models of generic zero-IF transmit and receive frontends, THz signals with different modulation formats and Baud rates are simulated at system level using the modeled LO phase noise for the two LO approaches.

Perhaps surprisingly,\r\n[Ambainis, CCC 2014] showed that the related, but arguably more natural,\r\nproblem of simulating local measurements on ground states of local Hamiltonians\r\n(APX-SIM) is likely harder than QMA. Indeed, [Ambainis, CCC 2014] showed that\r\nAPX-SIM is P^QMA[log]-complete, for P^QMA[log] the class of languages decidable\r\nby a P machine making a logarithmic number of adaptive queries to a QMA oracle.\r\nIn this work, we show that APX-SIM is P^QMA[log]-complete even when restricted\r\nto more physical Hamiltonians, obtaining as intermediate steps a variety of\r\nrelated complexity-theoretic results.\r\n  We first give a sequence of results which together yield P^QMA[log]-hardness\r\nfor APX-SIM on well-motivated Hamiltonians: (1) We show that for NP, StoqMA,\r\nand QMA oracles, a logarithmic number of adaptive queries is equivalent to\r\npolynomially many parallel queries. These equalities simplify the proofs of our\r\nsubsequent results. (2) Next, we show that the hardness of APX-SIM is preserved\r\nunder Hamiltonian simulations (a la [Cubitt, Montanaro, Piddock, 2017]). As a\r\nbyproduct, we obtain a full complexity classification of APX-SIM, showing it is\r\ncomplete for P, P^||NP, P^||StoqMA, or P^||QMA depending on the Hamiltonians\r\nemployed. (3) Leveraging the above, we show that APX-SIM is P^QMA[log]-complete\r\nfor any family of Hamiltonians which can efficiently simulate spatially sparse\r\nHamiltonians, including physically motivated models such as the 2D Heisenberg\r\nmodel.\r\n  Our second focus considers 1D systems: We show that APX-SIM remains\r\nP^QMA[log]-complete even for local Hamiltonians on a 1D line of 8-dimensional\r\nqudits.
