Fleas (95 Pulex irritans, 50 Ctenocephalides felis, 45 Ctenocephalides canis) and ixodid ticks (223 Ixodes ricinus, 231 Dermacentor reticulatus, 204 Haemaphysalis concinna) were collected in Hungary and tested, in assays based on PCR, for Bartonella infection. Low percentages of P. irritans (4.2%) and C. felis (4.0%) were found to be infected. The groEL sequences of the four isolates from P. irritans were different from all the homologous sequences for bartonellae previously stored in GenBank but closest to those of Bartonella sp. SE-Bart-B (sharing 96% identities). The groEL sequences of the two isolates from C. felis were identical with those of the causative agents of cat scratch disease, Bartonella henselae and Bartonella clarridgeiae, respectively. The pap31 sequences of B. henselae amplified from Hungarian fleas were identical with that of Marseille strain. No Bartonella-specific amplification products were detected in C. canis, I. ricinus, D. reticulatus and H. concinna pools.
Boosting as a very successful classification algorithm represents a great generalization ability with appropriate ensemble diversity. It can be easily applied in the two-class classification problem. However, sequential structure prediction, in which the output is an ordered list of the labeled classes, needs to be realized by an adjusted and extended version. For that purpose the AdaBoostSeq algorithm has been introduced. It performs the multi-class classification with respect to the sequential structure of the classification target. The profile of the AdaBoostSeq algorithm is analyzed in the paper, especially its classification accuracy, using various base classifiers applied to diverse experimental datasets with comparison to other state-of-the-art methods.
A topological space X is called base-base paracompact (John E. Porter) if it has an open base B such that every base B ′ ⊆ B has a locally finite subcover C ⊆ B′ . It is not known if every paracompact space is base-base paracompact. We study subspaces of the Sorgenfrey line (e.g. the irrationals, a Bernstein set) as a possible counterexample.
This text considers the early creative output of Ignác Cornova, in particular his lesserknown odes and his war poetry. It draws on contemporary research of the latter third of the 18th century focussing on the dynamic social change of the period, the transformation of the media, the emergence of a modern ‘public’, and changing perceptions of artistic as opposed to educational output. One of the difficulties of conceptualizing this period is the existence of two opposing trends – the older ‘Baroque’ tradition and the more ‘modern’ currents of the future national movement. Our text largely obviates this dichotomy by proposing a framework in which Cornova’s oeuvre is seen as evidence of an idiosyncratic cultural situation with its own features and markers. The aim of our study is to place Cornova’s early works within the literary context of his time – a context hard to appreciate today. We are not looking for the ‘future’ Cornova in those beginnings, nor the ‘embryos’ of his later development. Rather, we hope to rehabilitate the literary context in the Czech lands in the 1770s and 1780s as it veered between late Baroque odes, war reportage, and enlightenment patriotism. Alongside Cornova we consider now forgotten figures such as Vojtěch Koťara, Michael Denis, Johann Joseph Eberle and Václav Thám. The result is not a group biography, but rather a problem analysis of one segment of a period that defies unequivocal definition.
Die literaturhistorischen Arbeiten Zdeněk Mathausers sind hauptsächlich der Dichtung gewidmet, insbesondere der russischen. Sein Forschungsinteresse ist nicht auf die biographischen Umstände der Entwicklung der einzelnen Gedichte gerichtet, auch nicht auf ihre formale Beschreibung. Den Gegenstand seiner wissenschaftlichen Untersuchung kann man als phänomenologische Analyse "der eidetischen Struktur der lyrischen Erscheinung und lyrischen Wahrnehmung" bezeichnen. In dieser Hinsicht wirken in seinen Arbeiten fünf grundlegende Kategorien, auf die er in seinem Beitrag hinweist. In seinem Dichtungsverständnis erneuert Zdeněk Mathausers einige Seiten der Ästhetik der romantischen Epoche, welche auch voraussetzt, dass die Kunst den Menschen aus der prosaisch organisierten Welt ausschließen kann. and Ze symposií věnovaných Zdeňku Mathauserovi k 85. narozeninám
