Mittels Zeitrafferaufnahmen ist es möglich, einzelne Zellen und deren Nachkommenschaft innerhalb bestimmter Zellkulturen zu verfolgen. Fortgeschrittene Bilderverarbeitungsmethoden gestatten es, diesen Prozess der Zellverfolgung über Hunderte von aufeinanderfolgenden Bildern weitgehend zu automatisieren und baumartige Zelltrajektorien zu erzeugen. Allerdings kommt es dabei häufig zu Situationen, in denen die entsprechenden Algorithmen zu ungenau werden und ein Benutzereingriff erforderlich ist. Ziel dieser Arbeit war ein entsprechendes Softwaretool zu entwickeln, dass diesen Benutzereingriff gewährleistet und damit die automatische Zellverfolgung komplementiert. Die entsprechende Software ist in der Lage , die zu Grunde liegenden Bildstapel zu laden und als Bildsequenz darzustellen. Darüber hinaus werden zusätzliche Informationen zu den erkannten Zellobjekten und den automatisch generierten Zelltrajektoren (vor-prozessierte Metadaten aus Mathematica) geladen und repräsentiert. Zentrale Aufgabe der Software ist es, eine Plattform zu schaffen, auf der ein geschulter Nutzer die erkannten Trajektorienabschnitte effizient und benutzerfreundlich erkennen und gegebenenfalls miteinander verknüpfen kann. Die entsprechend ergänzten Trajektorien können anschliessend als Metadaten für die weitere Verarbeitung und Auswertung zur Verfügung gestellt werden. Das Softwaretool stellt einen wichtigen Bestandteil einer Auswertepipline für zeitlich ausgedehnte Videoaufnahmen von Zellkulturen dar und leistet damit einen Beitrag zum Verständnis von Zellorganisation und zellulärer Migration.

La présente thèse entend rendre compte d’un parcours de recherche entrepris il y a près de trente ans. Ces recherches ont connu divers développements pour lesquels une ligne conductrice peut cependant être dégagée : elles ont toutes trait à l’histoire des élites médiévales.Un premier axe concerne les enquêtes sur la société féodale de l’Orient latin. L’édition d’un texte généalogique, Les Lignages d’Outremer, a été le point de départ d’une série de publications sur ces familles, complétées par celle d’un récit de pèlerinage aux Lieux saints.Le second axe a pour objet la sigillographie. Le présent travail expose d’abord les travaux réalisés sur la sigillographie des reines et des enfants de France au Moyen Âge. L’autre volet de cette thématique a trait à la sigillographie des rois et empereurs des périodes mérovingienne et carolingienne, étude entreprise grâce à l’examen des 250 diplômes royaux conservés aux Archives nationales. À l’origine de ces publications, il y a une étonnante découverte, celle de la présence de cheveux humains dans les sceaux, pour laquelle nous tentons de trouver une explication, dans les diverses parties de ce travail et en particulier dans le mémoire De Anolo, joint au dossier.Enfin, un troisième axe est consacré à la pratique professionnelle que j’ai pu développer en tant que conservateur d’Archives. Les travaux proposés ici sont alors le témoignage des missions que j’ai pu exercer : au-delà de la publication d’instruments de recherche, une large place est faite aux problématiques de conservation préventive. / This thesis presents the results of research conducted over the past thirty years on the history of medieval elites.  The thesis focuses on two major topics. The first is the society of the Latin East. Publication of a genealogical text, Les lignages d’Outremer, has been followed by a series of studies of the noble families of the Latin Kingdom of Jerusalem and an edition of an account of a pilgrimage to the Holy Land. The second area is royal sigillography. Studies of the seals of medieval French queens and their children constitute one facet of this research, whereas examination of the seals found on 250 diplomas in the Archives nationales has facilitated exploration of the seals of Merovingian and Carolingian kings and emperors. The discovery of human hair in the seals has prompted the search for possible explanations of this phenomenon, which are proposed and discussed in different parts of the dossier, particularly in an appendix, "De anolo." An additional, supplementary part of my work has focused on the conservation of seals and the development of methods to prevent their deterioration.

Drawing on the methods of feminist art history and my own knowledge of the field, this PhD gives an overview of “Russian” (Russian Empire, Soviet, post-Soviet) art history with women at its center. Starting in the late 18th century and spanning to the present-day, I critically examine women’s artworks, the social contexts in which those women find themselves, as well as their biographies. Thus, this thesis extends beyond strict media analysis as a central concern of feminist criticism. This text consist of five chapters. Chapter One begins at the end of the 18th century and covers women artists working throughout the Russian Empire up through the beginning of the 20th century. Thesis looks at specific women artists and how the path to professionalization opened up new doors while women were still largely excluded from elite artistic circles. This overview demonstrates how this occurred both in explicit social exclusion as well as implicitly – specifically in the ways that the portrayals of women in professional art shifted throughout the 19th century. The ambivalent nature of women’s simultaneous inclusion and exclusion from leading art institutions and groups serves as a defining feature of the art world of the Russian Empire. Chapter Two examines women’s roles in the avant-garde at the beginning of the 20th century. As has been recognized in much popular scholarship, women served as key players in the so-called “Russian Avant-Garde”. For instance, while many Western European artists at the time turned to the colonies of their respective empires for stimulation, many Russian avant-garde artists turned to local peasants. Precisely because of their more differentiated relationships, Chapter Two argues that these women artists produced very dissimilar work from their Western European counterparts. This was due both to questions of gender as well as power and colonialism. From there, thesis shows the ways in which women avant-garde artists made use of various media – especially textiles, porcelain, and book design. Chapter Three revolves around women artists in the Soviet Union. At first it examines how women were portrayed in Socialist Realism, which followed largely three archetypes: the collective farm woman, the sportswoman, and the ballerina. In this chapter focus is on how women navigated the slippery terrain of the social world of Socialist Realism by highlighting the role of its most successful example – Vera Mukhina. Tracing through Mukhina’s path from the avant-garde to Socialist Realism’s most famous female artists, the text reveals continuities between the two genres that have typically been overlooked in the literature. Indeed, Mukhina’s development suggests much more in common between the avant-garde and Socialist Realism than most male artists’ careers would indicate. Finally, this chapter discusses women artists who rejected Socialist Realism and produced so-called “unofficial” art – focusing on the (in)famous Bulldozer Exhibition of 1974. Chapter Four illuminates how women artists negotiated the enormous socio-political changes during Perestroika through past the dissolution of the Soviet Union. In the 1990’s, three prominent all-women art collectives emerged: the Factory of Found Clothes, the Cyber-Femin Club, and the Fourth Height. Based largely on interviews with the women who participated in the groups, text sketches out a general history of how they formed, produced art, and confronted questions of gender and society. Then, chapter four turns to women artists who worked mostly individually throughout the same period. In this thesis women artists from the 90’s are categorized based on their concepts of gender – women who flipped gender dynamics through their art, women who took radical stances toward gender through their art, and women who did not clearly challenge ideas of gender. In the text they are called the “flip-floppers”, the “radicals”, and the “quietists”, respectively. In Chapter Five, there is a break with the chronological approach of the previous chapters. Instead, first part compares the trial of Iuliia Tsvetkova in 2019 and the trial of Natalia Goncharova in 1910. Both women were accused of producing pornography and thus subject to prosecution. Through this comparison, one can see the continuities and ruptures of the gender dynamics in broader society then and now, particularly in relationship to art and art production. Second part of the chapter five, compares the so-called “Leningrad Feminists” of the 1970’s and Pussy Riot from the 2010’s. By highlighting how these two collectives used the imagery of the Virgin Mary in their work, the text draws out parallels between the two that have gone unnoticed, even by the artists themselves. This dissertation is thus fundamentally about connections. Connections, both visible and invisible, define the social constellations in which women artists participate. By drawing out these connections, this thesis reimagines Russian art history and propose new, albeit imperfect, in the words of Amelia Jones, genealogies. Such genealogies open the space for a deep reckoning with the canon.:Table of Contents Introduction But What is a Russian Woman Artist Anyway?
