Discours, textes, traditions
(2016)
Ce qui sert de base et de cadre au présent volume, résultat d’une sectiondes journées des romanistes de langue allemande (Romanistentag) à Berlin, a fait l’objet de recherches intenses et de bien des controverses ces dernières années ; il s’agit de la fonction des traditions discursives, qui, en tant que savoir culturel et linguistique, nous apprennent à concevoir des textes et qui sont le pivot d’une analyse textuelle linguistique orientée vers la culture.

Visuelle und verbale Konzeptualisierungen von Trauer in einer Umbruchsituation: Allan Ramsay skizziert sein totes Kind
(2015)
The British painter Allan Ramsay’s physiognomic sketch of his first son, deceased at the age of 14 months in 1741, can provide some insight into the shift of emotional response towards death during the eighteenth century. Although never used for the execution of an autonomous painting according to available visual conventions, Ramsay directed the attention of his conversation partners to the image, apparently in an attempt to claim a stoic firmness of character for himself modelled on prototypes found in the tradition ...

Sprachwissenschaft als Kulturwissenschaft aus romanistischer Sicht: Das Beispiel der kontrastiven Pragmatik
(2014-03-01)
One of the central questions of pragmalinguistics is the distinction between linguistic structures and cultural norms that guide the usage of these structures in verbal interaction. is distinction is especially important for contrastive pragmatics, which analyses the interfaces of different languages and cultures. In order to draw a clear line between linguistic and cultural differences in patterns of interaction, contrastive pragmatics needs a methodological framework that is centred around a precise analytical ...

A simple retroelement based knock-down system in Dictyostelium
(PLoS, 2015)
Characteristics of DIRS-1 Mediated Knock-Downs __ We have previously shown that the most abundant Dictyostelium discoideum retroelement DIRS-1 is suppressed by RNAi mechanisms. Here we provide evidence that both inverted terminal repeats have strong promoter activity and that bidirectional expression apparently generates a substrate for Dicer. A cassette containing the inverted terminal repeats and a fragment of a gene of interest was sufficient to activate the RNAi response, resulting in the generation of ~21 nt ...

Hybrid optimization schemes for quantum control
(Springer Open, 2015)
Optimal control theory is a powerful tool for solving control problems in quantum mechanics, ranging from the control of chemical reactions to the implementation of gates in a quantum computer. Gradient-based optimization methods are able to find high fidelity controls, but require considerable numerical effort and often yield highly complex solutions. We propose here to employ a two-stage optimization scheme to significantly speed up convergence and achieve simpler controls. The control is initially parametrized ...

Enlarging a training set for genomic selction by imputation of un-genotyped animals in populations of varying genetic architecture
(BioMed Central, 2013)
Background: The most common application of imputation is to infer genotypes of a high-density panel of markers on animals that are genotyped for a low-density panel. However, the increase in accuracy of genomic predictions resulting from an increase in the number of markers tends to reach a plateau beyond a certain density. Another application of imputation is to increase the size of the training set with un-genotyped animals. This strategy can be particularly successful when a set of closely related individuals are ...

Increasing scepticism toward potential liars: effects of existential threat on veracity judgments and the moderating role of honesty norm activation
(Frontiers Research Foundation, 2015)
With the present research, we investigated effects of existential threat on veracity judgments. According to several meta-analyses, people judge potentially deceptive messages of other people as true rather than as false (so-called truth bias). This judgmental bias has been shown to depend on how people weigh the error of judging a true message as a lie (error 1) and the error of judging a lie as a true message (error 2). The weight of these errors has been further shown to be affected by situational variables. Given ...

The Effects of Visual Discriminability and Rotation Angle on 30-Month-Olds’ Search Performance in Spatial Rotation Tasks
(Frontiers Research Foundation, 2016-10-20)
Tracking objects that are hidden and then moved is a crucial ability related to object permanence, which develops across several stages in early childhood. In spatial rotation tasks, children observe a target object that is hidden in one of two or more containers before the containers are rotated around a fixed axis. Usually, 30-month-olds fail to find the hidden object after it was rotated by 180°. We examined whether visual discriminability of the containers improves 30-month-olds’ success in this task and whether ...

Exploiting non-Markovianity for quantum control
(Nature Publishing Group, 2015)
Quantum technology, exploiting entanglement and the wave nature of matter, relies on the ability to accurately control quantum systems. Quantum control is often compromised by the interaction of the system with its environment since this causes loss of amplitude and phase. However, when the dynamics of the open quantum system is non-Markovian, amplitude and phase flow not only from the system into the environment but also back. Interaction with the environment is then not necessarily detrimental. We show that the ...

Rembrandt als Vorbild englischer Künstler im 18. Jahrhundert
(2011)
Der niederlandische Maler Rembrandt Harmenszoon van Rijn gilt heute als eines der großen Malergenies der Vergangenheit. Diese außergewöhnliche Stellung, die der Künstler nur mit einer sehr kleinen Zahl ähnlich herausgehobener Künstlerkollegen aus den früheren Epochen der Kunstgeschichte teilt, ist ihm bekanntermafien erst im Laufe des 19. Jahrhunderts zugewachsen, als sich das Bedürfnis nach historischen Prototypen für den romantischen Künstlermythos mit unterschiedlichen Ausprägungen nationalis- tischer Inanspruchnahme ...
