De Grenade à Jérusalem

The present article examines the drama Birds of a Kind by the Lebanese-Canadian author Wajdi Mouawad. It analyses the allegorical character of Wazzan which is based on the historical figure Leo Africanus, a Moroccan diplomat and polymath of Granadan origin who in the early 16th century was kidnapped by Christian pirates and offered to Pope Leon X. Following his conversion from Islam to Catholicism he became the first author to present Africa to the Europeans through his works, published under the patronage of two popes from the Medici family. Leo Africanus was introduced to Mouawad by the American scholar Natalie Zemon Davis. In her study Trickster Travels (2006) she discusses the ambiguity and the evasiveness of this enigmatic historical figure whose character she highlights through the story of the amphibious bird. It is a parable placed as the author’s paratextual notice at the beginning of The Book of Cosmography and Geography of Africa (1526 [1550]), Leo Africanus’s most important scholarly work, and in spite of many possible sources, it is definitely his own invention. This article aims to demonstrate how Mouawad distanced his dramatic character from the original figure – the historiographic image of a trickster – by changing the point of the aforementioned parable. The story of the amphibious bird in Birds of a Kind, told by Wazzan to a Jew who right before his death is revealed to have an Arabic origin, is transformed form the parable of a trickster into a legend of someone who manages to overcome prejudice in order to find his identity. For Mouawad, Wazzan personifies the reconciliation between Judaism and Islam, transmitting at the same time an idea of the world dreamed of by the humanism of the Renaissance and Enlightenment.

Detection of 3D Arterial Centerline Extraction in Spiral CT Coronary Angiography

This paper presents an in-depth study and analysis of the 3D arterial centerline in spiral CT coronary angiography, and constructs its detection and extraction technique. The first time, the distance transform is used to complete the boundary search of the original figure; the second time, the distance transform is used to calculate the value of the distance transform of all voxels, and according to the value of the distance transform, unnecessary voxels are deleted, to complete the initial contraction of the vascular region and reduce the computational consumption in the next process; then, the nonwitnessed voxels are used to construct the maximum inner joint sphere model and find the skeletal voxels that can reflect the shape of the original figure. Finally, the skeletal lines were optimized on these initially extracted skeletal voxels using a dichotomous-like principle to obtain the final coronary artery centerline. Through the evaluation of the experimental results, the algorithm can extract the coronary centerline more accurately. In this paper, the segmentation method is evaluated on the test set data by two kinds of indexes: one is the index of segmentation result evaluation, including dice coefficient, accuracy, specificity, and sensitivity; the other is the index of clinical diagnosis result evaluation, which is to refine the segmentation result for vessel diameter detection. The results obtained in this paper were compared with the physicians’ labeling results. In terms of network performance, the Dice coefficient obtained in this paper was 0.89, the accuracy was 98.36%, the sensitivity was 93.36%, and the specificity was 98.76%, which reflected certain advantages in comparison with the advanced methods proposed by previous authors. In terms of clinical evaluation indexes, by performing skeleton line extraction and diameter calculation on the results obtained by the segmentation method proposed in this paper, the absolute error obtained after comparing with the diameter of the labeled image was 0.382 and the relative error was 0.112, which indicates that the segmentation method in this paper can recover the vessel contour more accurately. Then, the results of coronary artery centerline extraction with and without fine branch elimination were evaluated, which proved that the coronary artery centerline has higher accuracy after fine branch elimination. The algorithm is also used to extract the centerline of the complete coronary artery tree, and the results prove that the algorithm has better results for the centerline extraction of the complete coronary vascular tree.

The relationship between the so-called. "Physiological weight loss" and feeding the newborn baby

When observing the development of a newborn, we at first encounter from. vases. "Physiological weight loss" of it, expressed in the fact that in the first 3 days the baby loses weight on average 150-200 grams. so that by the 7-10th day his weight reaches the original figure (Budin'a type).

A change in the taxonomic rank of Senna andhrica P. V. Ramana, J. Swamy & M. Ahmed. (Fabaceae: Caesalpinioideae)

Senna andhrica P. V. Ramana, J. Swamy & M. Ahmed. is better treated as a variety of S. occidentalis (L.) Link, as S. occidentalis var. andhrica (P. V. Ramana, J. Swamy & M. Ahmedullah) K. W. Jiang, based on its diagnostic morphological characters of unifoliolate leaves and 2–3 carpellate gynoecium. Attention is drawn to an error in the original figure published with the description of Senna andhirica, the seeds specified by the authors are actually belong to a taxon of Crotalaria.

The Author

This chapter will examine Dante both as an historical author as well as the ‘author figure’ he performs in his texts, with particular attention to the tension between these two forms of authorship. The chapter proceeds through three interrelated sections: 1) Dante-poet and Dante-character; 2) Authorship and authority; and 3) Dante and autobiography. In each section the focus is not just on what Dante-the-author is but also on what Dantean authorship does. The casting of himself as the character of some of his works, the establishment of the authoritative status of vernacular poets alongside the ancients, and the ‘pact’ made with his readers are all strategies in the creation of his truly original figure of the author.

Discovering geometry via the Discover command in GeoGebra Discovery

We present a new way to discover statements in a planar geometric figure by using GeoGebra Discovery, an experimental version of GeoGebra, the free dynamic mathematics software package. A new command "Discover" (which is also available as a tool) requires an input point of the figure---as output several properties of the figure are communicated by the program. That is, "Discover" reports a list of the observed geometric properties, including point equality, equal long segments, collinearity, concyclicity, parallelism and perpendicularity. All of the obtained statements are checked symbolically: this means that the verification is done with computer algebra means. The obtained properties are also highlighted with colors or dashed lines in the original figure. The discovery process can always be continued by creating new objects and selecting a new target point to discover. We focus on possible uses in a classroom: two basic examples are shown from an Austrian textbook first. Then some more difficult topics are introduced that are usually covered by the secondary school curriculum. As a final example, we consider the discovery of a more advanced theorem, namely, a proposition according to Napoleon. We learn that discovery can lead to unexpected results, but this is an important characteristic of mathematics. In the paper we give some references to related software systems and the applied mathematical background as well.

Hierarchical Filling of N-Dimensional Spaces

The hierarchical filling of the n-dimensional space with geometric figures is studied, accompanied by a process of discrete similar changes in their sizes, that is, process of scaling. The scaling process in these fillings does not depend on time and is determined only by the geometric characteristics of the figures, which are preserved when their size is changed. Two possible ways of hierarchical filling of space are defined, under which the original figure incrementally increases its size fills the space. Investigations of the hierarchical filling of concrete geometric figures of a plane, three-dimensional space, four- and five-dimensional spaces are carried out. The denominator of geometric progressions characterizing sequences of figures in the process of scaling are determined depending on the shape of the figure and its dimension.

Correction to: Disinformation in Open Online Media

In the original online version of the chapter 5 was previously published non-open access. It was changed to open access retrospectively under a CC BY 4.0 license and, the presentation of Table 3 was different to that of Tables 2 and 4. This has been corrected. In addition, Tables 5 - 8 have been moved from the main text to Appendix B, at the request of the authors.The original version of the chapter 11 contained an error in Table 2, which also affected Section 3.1 and the Conclusion. The original figure in Table 2 indicated that one community was retweeting from a smaller number of accounts than the other communities. A recalculation following publication showed that the community was retweeting from a pool of about the same number of accounts as the other communities. This has been updated.

Aleuroclava aucubae (Homoptera: Aleyrodinea), a new adventive species for Russian Black Sea Coast, and its concomitant entomoparasitic fungus Conoideocrella luteorostrata (Ascomycota: Hypocreales: Clavicipitaceae)

An Oriental species of whiteflies, Aleuroclava aucubae (Kuwana, 1911), was collected for the first time from the territory of Russia (the Black Sea Coast of Russian Caucasus, Sochi National Park). The species was found to form dense colonies of ultimolarvae (pseudopupae) on leaves of Ficus carica and Ulmus glabra. Some of the ultimolarvae were infected by the fungus Conoideocrella luteorostrata (Zimmermann, 1901) Johnson et al., 2009. A morphological description of the pseudopupa of A. aucubae, with the original figure and photos are provided.
