We investigated if it is possible to use auditory stimuli to create a BCI for the Japanese Hiragana syllabary, which has 46 Hiragana characters. Additionally, we investigated if training has an effect on accuracy despite the high amount of different stimuli involved. Able-bodied participants (N = 6) were asked to select 25 syllables (out of fifty possible choices) using a two step procedure: First the consonant (ten choices) and then the vowel (five choices). This was repeated on 3 separate days. Additionally, a person with spinal cord injury (SCI) participated in the experiment. Four out of six healthy participants reached Hiragana syllable accuracies above 70% and the information transfer rate increased from 1.7 bits/min in the first session to 3.2 bits/min in the third session. The accuracy of the participant with SCI increased from 12% (0.2 bits/min) to 56% (2 bits/min) in session three. Reliable selections from a 10 × 5 matrix using auditory stimuli were possible and performance is increased by training. We were able to show that auditory P300 BCIs can be used for communication with up to fifty symbols. This enables the use of the technology of auditory P300 BCIs with a variety of applications.

L’argumentation de François Hollande face aux attaques terroristes du 13 novembre JF - promptus - Würzburger Beiträge zur Romanistik N2 - After the terrorist attacks on November 13th, the French public, the whole of Europe and many parts of the world were waiting for president François Hollande to address his fellow “citoyens”. Being the most important political figure – both by constitution and by influence on public discourse – the president’s words bear great importance for the subsequent debate and interpretation of the events. Therefore, the question arises: How did the president shape the debate in the hours and days after the attacks? To answer this question, we have identified typical structures in Hollande’s rhetorical reaction to the attacks, performing a topos as well as a keyword analysis of the speeches the president held within two weeks after November 13th. In a contrastive analysis we have compared Hollande’s speeches to the Europarl Corpus. Using the software programme sketch engine, we have filtered out the 100 most frequent keywords and classified them into semantic fields (data-driven approach). All in all, terrorism, action and nation/identity are the three predominant semantic fields, whereas references to victimhood barely appear. These findings are congruent with the results of our topos analysis that reveals a predominance of argumentative structures that form a strong main topos of resilience, emphasising the greatness of France and its people and culture, calling to action and avoiding any tendencies of resignation.

Ein Beitrag zur Entstehungsgeschichte des romantischen epischen Gedichts in Hispanoamerika JF - promptus - Würzburger Beiträge zur Romanistik N2 - This article concentrates on the Argentine author Esteban Echeverría who is known as the founding father of Romanticism in the River Plate region. The author of this article intends to show that the importance of Echeverría for the development of Argentine national literature goes beyond the spreading of Romanticist aesthetics. Especially his poem La cautiva (1837) has been regarded as the national epic poem of Argentina because it represents national landscape and the early days of national history. However, as the classification of this narrative poem as the national epic poem already indicates, Echeverría also contributed to the presence of this prestigious genre at the River Plate region. By investigating Echeverría‘s less known verse texts – namely the texts which were read by all Romantics but which have been neglected by literary studies so far – this article illustrates that Echeverría gave decisive impulses for the presence of the epic poem at the River Plate.

In both travel writings, the author is torn between aesthetic japonism – which spread all over Europe at the end of the 19th century – and exotic expectations, i.e. the picturesque fascination of the Other. The latter, however, remains unsatisfied throughout his stay. In both writings, Pierre Loti provides an insight into Japan that entirely reflects the spirit of his time. Thereby, he contributes to an image of Japan, which will long remain vivid in the Occident. Contemporaries perceive Loti’s representation of Japan as a realistic testimony, tinged with both sensory impressions and his highly ambiguous feelings towards the distant country, which in the end remained incomprehensible to him.

Une comparaison entre la représentation du corps mort dans le De Miseria Condicionis Humane d’Innocent III et dans son adaptation française Double lay de fragilité humaine d’Eustache Deschamps JF - promptus - Würzburger Beiträge zur Romanistik N2 - The study uses the category of disgust in order to analyse the representation of the human body and the corpse in one of the most influential medieval treatises, the De Miseria Condicionis Humanae (1195) written by Pope Innocent III, and its little known old French adaptation Double lay de fragilité humaine (1383) by Eustache Deschamps. Analysing how both use disgust as an aesthetic means, which appeals to emotions and turns off reason, helps to point out the pedagogical and moral function of the texts. The comparison between them shows that Deschamps stays faithful to his Latin model, but that he nevertheless has to make certain modifications in order to adapt the prose text into a lyrical form. Furthermore, this approach clearly elucidates what differences there are between the conceptions of the human body and death in the two texts, revealing at the same time divergent theological points of view.

Through oral tradition, they transfer the cultural and family knowledge from one generation of women to the next. We will offer an analysis of oral transmission as a way of preserving a memory of women in Le livre d’Emma (2001) by the Québec author of Haitian origin, Marie-Célie Agnant. We will primarily analyze the transformation of communicative memory into cultural memory, following the distinction by Jan Assmann. We will interpret the oral transfer as a possibility to stabilize, to legitimize female memory and to inscribe it into the female body.

T1 - Comparison of nonculture blood-based tests for diagnosing invasive aspergillosis in an animal model JF - Journal of Clinical Microbiology N2 - The European Aspergillus PCR Initiative (EAPCRI) has provided recommendations for the PCR testing of whole blood (WB) and serum/plasma. It is important to test these recommended protocols on nonsimulated "in vivo" specimens before full clinical evaluation. The testing of an animal model of invasive aspergillosis (IA) overcomes the low incidence of disease and provides experimental design and control that is not possible in the clinical setting. Inadequate performance of the recommended protocols at this stage would require reassessment of methods before clinical trials are performed and utility assessed. The manuscript describes the performance of EAPCRI protocols in an animal model of invasive aspergillosis. Blood samples taken from a guinea pig model of IA were used for WB and serum PCR. Galactomannan and beta-D-glucan detection were evaluated, with particular focus on the timing of positivity and on the interpretation of combination testing. The overall sensitivities for WB PCR, serum PCR, galactomannan, and beta-D-glucan were 73%, 65%, 68%, and 46%, respectively. The corresponding specificities were 92%, 79%, 80%, and 100%, respectively. PCR provided the earliest indicator of IA, and increasing galactomannan and beta-D-glucan values were indicators of disease progression. The combination of WB PCR with galactomannan and beta-D-glucan proved optimal (area under the curve AUC], 0.95), and IA was confidently diagnosed or excluded. The EAPRCI-recommended PCR protocols provide performance comparable to commercial antigen tests, and clinical trials are warranted. By combining multiple tests, IA can be excluded or confirmed, highlighting the need for a combined diagnostic strategy. However, this approach must be balanced against the practicality and cost of using multiple tests.

A1 - Parkhill, Julian T1 - The TraDIS toolkit: sequencing and analysis for dense transposon mutant libraries JF - Bioinformatics N2 - Transposon insertion sequencing is a high-throughput technique for assaying large libraries of otherwise isogenic transposon mutants providing insight into gene essentiality, gene function and genetic interactions. We previously developed the Transposon Directed Insertion Sequencing (TraDIS) protocol for this purpose, which utilizes shearing of genomic DNA followed by specific PCR amplification of transposon-containing fragments and Illumina sequencing. Here we describe an optimized high-yield library preparation and sequencing protocol for TraDIS experiments and a novel software pipeline for analysis of the resulting data. The Bio-Tradis analysis pipeline is implemented as an extensible Perl library which can either be used as is, or as a basis for the development of more advanced analysis tools. This article can serve as a general reference for the application of the TraDIS methodology.

Direct comparisons between child and adult populations are needed to determine developmental risk markers of fear and anxiety. We compared 267 children and 285 adults in a differential fear conditioning paradigm and generalization test. Skin conductance responses (SCR) and ratings of valence and arousal were obtained to indicate fear learning. Both groups displayed robust and similar differential conditioning on subjective and physiological levels. However, children showed heightened fear generalization compared to adults as indexed by higher arousal ratings and SCR to the generalization stimuli. Results indicate overgeneralization of conditioned fear as a developmental correlate of fear learning. The developmental change from a shallow to a steeper generalization gradient is likely related to the maturation of brain structures that modulate efficient discrimination between danger and (ambiguous) safety cues.

As a part of this network, the heteromeric transcription factor GA-binding protein (GABP) plays a crucial role in self-renewal of murine hematopoietic and leukemic stem cells. Here, we report the consequences of functional impairment of GABP in human hematopoietic and in leukemic stem/progenitor cells. Ectopic overexpression of a dominant-negative acting GABP mutant led to impaired myeloid differentiation of CD34\(^{+}\) hematopoietic stem/progenitor cells obtained from healthy donors. Moreover, drastically reduced clonogenic capacity of leukemic stem/progenitor cells isolated from bone marrow aspirates of chronic myeloid leukemia (CML) patients underlines the importance of GABP on stem/progenitor cell maintenance and confirms the relevance of GABP for human myelopoiesis in healthy and diseased states.
