While transverse walk-off can be eliminated by proper medium engineering, longitudinal walk-off is harder to avoid. In particular, ultrafast twin-beam generation via pulsed parametric down-conversion and four-wave mixing is only possible in short crystals or fibres. Here we show that in high-gain parametric down-conversion, one can overcome the destructive role of both effects and even turn them into useful tools for shaping the emission. In our experiment, one of the twin beams is emitted along the pump Poynting vector or its group velocity matches that of the pump. The result is markedly enhanced generation of both twin beams, with the simultaneous narrowing of angular and frequency spectrum. The effect will enable efficient generation of ultrafast twin photons and beams in cavities, waveguides and whispering-gallery mode resonators.}}, author = {{Pérez, Angela M. and Spasibko, Kirill Yu and Sharapova, Polina and Tikhonova, Olga V. and Leuchs, Gerd and Chekhova, Maria V.}}, issn = {{2041-1723}}, journal = {{Nature Communications}}, keywords = {{General Physics and Astronomy, General Biochemistry, Genetics and Molecular Biology, General Chemistry, Multidisciplinary}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Giant narrowband twin-beam generation along the pump-energy propagation direction}}}, doi = {{10.1038/ncomms8707}}, volume = {{6}}, year = {{2015}}, } @article{4035, abstract = {{We examine whether the mandated introduction of International Financial Reporting Standards (IFRS) is associated with the propensity to access the public rather than private debt market and the cost of debt.

Though a lot of work is currently being conducted to develop PHM systems for fuel cells, various challenges have been encountered including the self-healing effect after characterization as well as accelerated degradation due to dynamic loading, all which make RUL predictions a difficult task. In this study, a prognostic approach based on adaptive particle filter algorithm is proposed. The novelty of the proposed method lies in the introduction of a self-healing factor after each characterization and the adaption of the degradation model parameters to fit to the changing degradation trend. An ensemble of five different state models based on weighted mean is then developed. The results show that the method is effective in estimating the remaining useful life of PEM fuel cells, with majority of the predictions falling within 5\% error.

The findings are gathered in a probabilistic formulation of an observation model which may be used in model-based feature compensation schemes. The proposed observation model extends previous models in three major directions: First, the contribution of additive background noise to the observation error is explicitly taken into account. Second, an energy compensation constant is introduced which ensures an unbiased estimate of the reverberant speech features, and, third, a recursive variant of the observation model is developed resulting in reduced computational complexity when used in model-based feature compensation.

However, students with more sophisticated sustainability knowledge seemed to scrutinize the given sustainability information more deeply, while students with “pure” accounting knowledge seemed more willing to simply accept the information.Practical implications– The authors argue for advancements in the curriculum for business students that foster critical thinking and might prevent students (and thus potential future managers) from using sustainability information superficially.

Regarding the ontogenesis of literary research discourse over the past 50 years, Käte Hamburger’s “The Logic of Poetry” (original “Die Logik der Dichtung”, 1957) is a work that has fundamentally shaped the research discourse. But not only within the field of literary studies has the subject of “tense and narration” has been received and discussed – also the field of linguistics also demonstrates an intensive engagement with the subject of narration (cf. e. g. Weinrich 1964, Ehlich 1980) and tense. For example, Rolf Thieroffs monograph “The finite Verb in German: Tense – Mood – Distance” (original “Das finite Verb im Deutschen: Tempus – Modus – Distanz”, 1992) elaborates a conceptualisation of the German temporal system with reference to Weinrich’s representation of time in fiction and non-fiction texts (cf. Thieroff 1992, 298). This contribution joins at the interface between linguistic research on tenses and literary research on narration. The aim is to show that there is an interaction between choice of tense and narrative context, or, in other words: the use of different tenses activates different states of consciousness, and thereby different ‘forms’ of narration are created. The latter are captured from empirical data arising from language acquisition and speech genesis as well as, in accordance with Iser (1991) and Sartre (1940/1994), not in a dichotomic fashion but as a trias-system, and are opened for discussion. The remodeling does not regard the two poles of “every­day narration” and “literary narration” as contrasting, but rather as a continuum, which can show transitions relative to the genre of the text and the speech competence of the narrator.}}, author = {{Topalović, Elvira and Uhl, Benjamin}}, issn = {{1613-0626}}, journal = {{Zeitschrift für germanistische Linguistik}}, keywords = {{Linguistics and Language, Developmental and Educational Psychology, Language and Linguistics}}, number = {{1}}, pages = {{26--49}}, publisher = {{Walter de Gruyter GmbH}}, title = {{{Linguistik des literarischen Erzählens}}}, doi = {{10.1515/zgl-2014-0002}}, volume = {{42}}, year = {{2014}}, }
