No animals were used in the making of this film? : post-animals and the call of anthropomorphism in the era of CGI
No full textArtykuł traktuje o wpływie rewolucji cyfrowej na reprezentacje zwierząt w filmach fabularnych. Autor analizuje zwierzęta generowane komputerowo w kontekście rozwoju CGI oraz skutków bezszwowego łączenia fotorealistycznej animacji z materiałem live action. Wpisuje zjawisko rozwijające się od lat 90. w kontekst studiów nad efektami wizualnymi i animal studies. Szczególną uwagę zwraca na kwestię postępującej antropomorfizacji cyfrowych zwierząt w obrębie kina live action ostatniej dekady. Autor wyróżnia trzy podstawowe strategie kreowania percepcyjnie realistycznych zwierząt w zależności od stopnia ich wewnętrznego uczłowieczenia oraz zewnętrznej antropomorfizacji i kreskówkowości. Analizując m.in. "Króla Lwa" (reż. J. Favreau, 2019), autor zauważa nowy trend, charakterystyczny dla kina hybrydycznego (stopu fotorealistycznej animacji i materiału live action) - reprezentacje głęboko antropomorfizowanej fauny zachowującej hiperrealistyczną powierzchowność.The article explores the impact of the digital revolution on animal representation in feature films. The author analyses computer-generated animals in the context of the progress of CGI and the effects of seamlessly compositing photorealistic animation with live action material. The author studies the phenomenon that has been developing since the 1990s in the context of visual effects studies and animal studies. He emphasizes the issue of progressive anthropomorphising of digital animals in the live action cinema of the last decade. The author differentiates three basic strategies for creating perceptually realistic animals, depending on the degree of their internal personification and external anthropomorphism or cartoonishness. Analysing "The Lion King" (dir. J. Favreau, 2019) the author notes a new trend, characteristic of hybrid cinema (a mélange of photorealistic animation and live action material): representations of deeply anthropomorphized fauna maintaining hyper-realistic physiognomy
Les inscriptions des fonts baptismaux d'Hildesheim, Baptême et quaternité
No full textThe baptismal font of Hildesheim cathedral is an extraordinary work by its artistic quality, the opulence of the iconographie programm and the profusion of inscriptions that inform us about the intentions of the author, his theologic, patristic, and literary culture. This elaborated programm associates the rivers of paradise with the cardinal virtues, major prophets and Gospel-writers ; the four great scenes of the bowl — donation, figures of the baptism — are in relation with the four great scenes of the lid that show the four kinds of baptism — water, martyrdom, penance, and good works. This iconography and this epigraphic commentary allow to understand better how the Church lived the sacrament of baptism during the XIIIth century.Les fonts baptismaux de la cathédrale d'Hildesheim constituent une œuvre remarquable par leur qualité artistique, la richesse du programme iconographique, l'abondance de l'accompagnement épigraphique. Les inscriptions nous éclairent sur les intentions de l'auteur, sa culture théologique, patristique, littéraire. Une construction savante met en relation fleuves du paradis, vertus cardinales, grands prophètes, évangélistes ; les quatre grandes scènes de la cuve — donation, figures du baptême — sont en rapport avec les quatre grandes scènes du couvercle qui présentent les quatre genres de baptême — l'eau, le martyre, la pénitence, les bonnes œuvres. À travers cette iconographie et son commentaire épigraphique nous pouvons mieux comprendre la façon dont l'Église, au xme s., vivait le sacrement de baptême.Favreau Robert.

Comment traduire la voix d’une autrice ancrée à la fois dans l’objectivité et dans la subjectivité : le cas du récit-essai Two Trees Make a Forest, de Jessica J. Lee
No full textCe mémoire aborde la question de la traduction de la voix d’une autrice et porte sur le récit-essai Two Trees Make a Forest de Jessica J. Lee. Cette œuvre étant traversée par tout un réseau de relations entre les niveaux de l’expression et ceux du contenu, la traductrice visant à limiter la superposition de sa voix à celle de Lee doit s’assurer de reproduire les particularités génériques de l’œuvre, l’inscription mouvante de la voix de l’autrice sur l’axe allant de l’objectivité à la subjectivité et les traits constitutifs de son lyrisme. Elle doit aussi les mettre en relation de façon à préserver la signifiance de l’œuvre. Le mémoire présente le cadre théorique dans lequel se situe ce projet de traduction, plusieurs exemples concrets d’applications de celui-ci ainsi que la traduction française d’une soixantaine de pages de Two Trees Make a Forest.Abstract: This M.A. thesis explores the translation of an author's voice, focusing on Jessica J. Lee's
narrative-essay Two Trees Make a Forest. As the book presents a complex network of
relations between levels of expression and content, the translator aiming at limiting the
superposition of her own voice to Lee’s must ensure that she reflects the generic
particularities of the work, the moving inscription of the author's voice on the axis ranging
from objectivity to subjectivity and the features of her lyricism. She must also respect the
way they are articulated in order to preserve the significance of this literary work. The thesis
presents the theoretical framework for this translation project, several examples of its
applications as well as the French translation of sixty pages of Two Trees Make a Forest
Interactions among social monitoring, anti-predator vigilance and group size in eastern grey kangaroos
No full textGroup size is known to affect both the amount of time that prey animals spend in vigilance and the degree to which the vigilance of group members is synchronized. However, the variation in group-size effects reported in the literature is not yet understood. Prey animals exhibit vigilance both to protect themselves against predators and to monitor other group members, and both forms of vigilance presumably influence group-size effects on vigilance. However, our understanding of the patterns of individual investment underlying the time sharing between anti-predator and social vigilance is still limited. We studied patterns of variation in individual vigilance and the synchronization of vigilance with group size in a wild population of eastern grey kangaroos (Macropus giganteus) subject to predation, in particular focusing on peripheral females because we expected that they would exhibit both social and anti-predator vigilance. There was no global effect of group size on individual vigilance. The lack of group-size effect was the result of two compensating effects. The proportion of time individuals spent looking at other group members increased, whereas the proportion of time they spent scanning the environment decreased with group size; as a result, overall vigilance levels did not change with group size. Moreover, a degree of synchrony of vigilance occurred within groups and that degree increased with the proportion of vigilance time peripheral females spent in anti-predator vigilance. Our results highlight the crucial roles of both social and anti-predator components of vigilance in the understanding of the relationship between group size and vigilance, as well as in the synchronization of vigilance among group members. © 2010 The Royal Society

[As] he observed and drew [them] together, his heart wondered and he was glad when [many] had been directed to him across the great sea, especially those of Genoa, Venice and Pisa. The strength of the nations came to him, especially from France and Germany.
Co-expression Gene Networks and Machine-learning Algorithms Unveil a Core Genetic Toolkit for Reproductive Division of Labour in Rudimentary Insect Societies
No full textThe evolution of eusociality requires that individuals forgo some or all their own reproduction to assist the reproduction of others in their group, such as a primary egg-laying queen. A major open question is how genes and genetic pathways sculpt the evolution of eusociality, especially in rudimentary forms of sociality—those with smaller cooperative nests when compared with species such as honeybees that possess large societies. We lack comprehensive comparative studies examining shared patterns and processes across multiple social lineages. Here we examine the mechanisms of molecular convergence across two lineages of bees and wasps exhibiting such rudimentary societies. These societies consist of few individuals and their life histories range from facultative to obligately social. Using six species across four independent origins of sociality, we conduct a comparative meta-analysis of publicly available transcriptomes. Standard methods detected little similarity in patterns of differential gene expression in brain transcriptomes among reproductive and non-reproductive individuals across species. By contrast, both supervised machine learning and consensus co-expression network approaches uncovered sets of genes with conserved expression patterns among reproductive and non-reproductive phenotypes across species. These sets overlap substantially, and may comprise a shared genetic “toolkit” for sociality across the distantly related taxa of bees and wasps and independently evolved lineages of sociality. We also found many lineage-specific genes and co-expression modules associated with social phenotypes and possible signatures of shared life-history traits. These results reveal how taxon-specific molecular mechanisms complement a core toolkit of molecular processes in sculpting traits related to the evolution of eusociality.This article is published as Emeline Favreau, Katherine S Geist, Christopher D R Wyatt, Amy L Toth, Seirian Sumner, Sandra M Rehan, Co-expression Gene Networks and Machine-learning Algorithms Unveil a Core Genetic Toolkit for Reproductive Division of Labour in Rudimentary Insect Societies, Genome Biology and Evolution, Volume 15, Issue 1, January 2023, evac174, https://doi.org/10.1093/gbe/evac174.© The Author(s) 2022.

<h2>Paper abstract </h2>
<div>We present the results of exploring the capabilities of skinning modifiers to generate high fidelity polygonal surface meshes of neurons from their morphological skeletons that are segmented from optical microscopy slides. Our algorithm is implemented in Blender as an add-on relying on its standard Python API. The implementation is also integrated into an open source domain specific framework, NeuroMorphoVis, that is used to visualize and analyze neuronal morphologies available from the neuroscientific community. Our technique is applied to create meshes for a set of neurons with 55 different morphologies reconstructed from the neocortex of a 14-days-old rat. The generated meshes are used to visualize full compartmental simulations of neocortical activity for analysis purposes and also to create high quality scientific illustrations of in silico neuronal circuits for media production with physically-based path tracers.</div>

SCADA and related technologies
No full textPresented at SCADA and related technologies for irrigation district modernization, II: a USCID water management conference held on June 6-9, 2007 in Denver, Colorado.This paper presents an application of Supervisory Control and Data Acquisition (SCADA) in three countries of Central Asia: Uzbekistan, Kyrgyzstan and Tajikistan. The project is financed by the Swiss Development Agency for Cooperation (SDC). The objectives of this project are to stabilize the flows diverted for irrigation downstream from large hydro-power plants and to monitor the equity and reliability of water diverted to secondary canals. This application provides an example of a promising success story in irrigation modernization in developing countries. Three factors may contribute to this success: i) the existence of a regional automation company, ii) the use of factory-made control equipment and iii) the rapid intervention of the local industry when repairs or corrections to control equipment are needed. The project also demonstrates that modernization of irrigation systems can be completed at a reasonable cost. The paper presents the results of the first series of tests of the SCADA system and highlights some of the differences in the design of SCADA projects between developed and developing countries
