The project investigates the language abilities of multilingual children and adolescents, in particular, those who have Turkish and/or Kurdish as a mother tongue. A further aim of the project is to examine from a psycholinguistic and sociolinguistic perspective the extent to which competence in academic registers is achieved on the basis of the languages spoken by the children, including the language(s) spoken at the home, the language of the country of residence and the first foreign language. To be able to examine these questions using corpus linguistic parameters, we created categories of analysis in MULTILIT. The data collection comprises texts from bilingual and monolingual children and adolescents in Germany in their first language Turkish, their second language German und their foreign language English. Pupils aged between nine and twenty years of age produced monologue oral and written texts in the two genres of narrative and discursive. On the basis of these samples, we examine linguistic features such as lexical expression (lexical density, lexical diversity), syntactic complexity (syntactic and discursive packaging) as well as phonology in the oral texts and orthography in the written texts, with the aim of investigating the pupils’ growing mastery of these features in academic and informal registers. To this end the raw data have been transcribed by the use of transcription conventions developed especially for the needs of the MULTILIT data. They are based on the commonly used HIAT and GAT transcription conventions and supplemented with conventions that provide additional information such as features at the graphic level. The categories of analysis comprise a large number of linguistic categories such as word classes, syntax, noun phrase complexity, complex verbal morphology, direct speech and text structures. We also annotate errors and norm deviations at a wide range of levels (orthographic, morphological, lexical, syntactic and textual). In view of the different language systems, these criteria are considered separately for all languages investigated in the project. N2 - Die vorliegende Arbeit stellt eine Übersicht der linguistischen Analysen dar, die im Rahmen des MULTILIT Projektes entwickelt wurden. Darüber hinaus wird die Aufbereitung der erhobenen mündlichen und schriftlichen Texte vorgestellt. Das Projekt betrachtet die sprachlichen Fähigkeiten multilingualer Kinder und Jugendlicher, insbesondere mit der Muttersprache Türkisch und/oder Kurdisch. Ein weiteres Ziel des Projektes ist die Untersuchung der Entwicklung eines akademischen Registers der Sprachen der Kinder, d.h. der zu Hause gesprochenen Sprache(n), der Sprache des Aufenthaltslandes und der ersten Fremdsprache unter psycholinguistischen und soziolinguistischen Gesichtspunkten. Zur Untersuchung dieser Forschungsfragen unter korpuslinguistischen Parametern wurden in MULTILIT Analysekriterien entwickelt. Die Datenerhebung umfasst Texte bilingualer und monolingualer Kinder und Jugendlicher in ihrer Erstsprache Türkisch, ihrer Zweitsprache Deutsch sowie ihrer ersten Fremdsprache Englisch. Schüler im Alter von 9 bis 20 Jahren haben sowohl mündliche als auch schriftliche monologische Texte in zwei Genres produziert – erzählend und erörternd. Basierend auf diese Daten untersuchen wir linguistische Bereiche wie lexikalischer Ausdruck (lexikalische Dichte, lexikalische Vielfalt), syntaktische Komplexität (syntaktische und diskursive Verdichtung) sowie Phonologie in den mündlichen Texten und Orthographie in den schriftlichen Texten mit dem Ziel, die wachsende Beherrschung dieser Bereiche in akademischen und informellen Registern durch die Schüler zu untersuchen. Dafür wurden die Rohdaten mit Transkriptionskonventionen verarbeitet, die speziell auf die Bedürfnisse des MULTILIT Projektes zugeschnitten sind. Sie basieren auf den weit verbreiteten Transkriptionskonventionen HIAT und GAT und wurden durch Konventionen erweitert, die zusätzliche Informationen, beispielsweise auf graphischer Ebene, festhalten. Die Analysekategorien umfassen zahlreiche linguistische Kategorien, wie Wortarten, Syntax, Nominalphrasenkomplexität, komplexe Verbalmorphologie, direkte Rede und Textstrukturen. Außerdem annotieren wir Fehler und Normabweichungen auf allen zahlreichen Ebenen (orthographisch, morphologisch, lexikalisch, syntaktisch und textuell). Aufgrund der verschiedenen Sprachsysteme werden diese Analysekategorien für alle im Projekt untersuchten Sprachen gesondert betrachtet.

The population of those orbitals and the energetic difference between the two reflect the strength of the bonding interaction. Weakening the bond is expected to reduce this energetic splitting, but the transient character of bond-activation has so far prohibited direct experimental access. Here we apply time-resolved soft X-ray spectroscopy at a free electron laser to directly observe the decreased bonding antibonding splitting following bond-activation using an ultrashort optical laser pulse.

Vacuum space-charge effects can mask these dynamics and complicate the interpretation of electron spectra. Here we report on space-charge effects in Au 4f photoemission from a polycrystalline gold surface, excited with moderately intense 90 ps (FWHM) soft x-ray probe pulses, under the influence of the Coulomb forces exerted by a pump electron cloud, which was produced by intense 40 fs laser pulses. The experimentally observed kinetic energy shift and spectral broadening of the Au 4f lines, measured with highly-efficient time-of-flight spectroscopy, are in good agreement with simulations utilizing a mean-field model of the electrostatic pump electron potential. This confirms that the line broadening is predominantly caused by variations in the take-off time of the probe electrons without appreciable influence of local scattering events. Our findings might be of general interest for pump-probe PES with picosecond-pulse-length sources.

The X-ray spectroscopic core-hole-clock method prepares selectively in-and out-of-plane polarized sulfur 3p orbital occupation with respect to the 1T-TaS2 planes and monitors sub-femtosecond wave packet delocalization. Despite being a prototypical two-dimensional material, isotropic three-dimensional charge transfer is found in the commensurate charge density wave phase (CCDW), indicating strong coupling between layers. In contrast, anisotropic two-dimensional charge transfer occurs for the nearly commensurate phase (NCDW). In direct comparison, theory shows that interlayer interaction in the CCDW phase - not layer stacking variations - causes isotropic three-dimensional charge transfer. This is presumably a general mechanism for phase transitions and tailored properties of dichalcogenides with charge density waves.

The mouse genome involves seven functional Alox genes and the encoded enzymes share a high degree of amino acid conservation with their human orthologs. There are, however, functional differences between mouse and human ALOX orthologs. Human ALOX15B oxygenates arachidonic acid exclusively to its 15-hydroperoxy derivative (15S-HpETE), whereas 8S-HpETE is dominantly formed by mouse Alox15b. The structural basis for this functional difference has been explored and in vitro mutagenesis humanized the reaction specificity of the mouse enzyme. To explore whether this mutagenesis strategy may also humanize the reaction specificity of mouse Alox15b in vivo, we created Alox15b knock-in mice expressing the arachidonic acid 15-lipoxygenating Tyr603Asp+His604Val double mutant instead of the 8-lipoxygenating wildtype enzyme. These mice are fertile, display slightly modified plasma oxylipidomes and develop normally up to an age of 24 weeks. At later developmental stages, male Alox15b-KI mice gain significantly less body weight than outbred wildtype controls, but this effect was not observed for female individuals. To explore the possible reasons for the observed gender-specific growth arrest, we determined the basic hematological parameters and found that aged male Alox15b-KI mice exhibited significantly attenuated red blood cell parameters (erythrocyte counts, hematocrit, hemoglobin). Here again, these differences were not observed in female individuals. These data suggest that humanization of the reaction specificity of mouse Alox15b impairs the functionality of the hematopoietic system in males, which is paralleled by a premature growth arrest.
