Project Reassessing Ninth Century Philosophy. A Synchronic Approach to the Logical Traditions
Researcher (PI) Christophe Florian Erismann
Host Institution (HI) UNIVERSITAT WIEN
Call Details Consolidator Grant (CoG), SH5, ERC-2014-CoG
Summary This project aims at a better understanding of the philosophical richness of ninth century thought using the unprecedented and highly innovative method of the synchronic approach. The hypothesis directing this synchronic approach is that studying together in parallel the four main philosophical traditions of the century – i.e. Latin, Greek, Syriac and Arabic – will bring results that the traditional enquiry limited to one tradition alone can never reach. This implies pioneering a new methodology to overcome the compartmentalization of research which prevails nowadays. Using this method is only possible because the four conditions of applicability – comparable intellectual environment, common text corpus, similar methodological perspective, commensurable problems – are fulfilled. The ninth century, a time of cultural renewal in the Carolingian, Byzantine and Abbasid empires, possesses the remarkable characteristic – which ensures commensurability – that the same texts, namely the writings of Aristotelian logic (mainly Porphyry’s Isagoge and Aristotle’s Categories) were read and commented upon in Latin, Greek, Syriac and Arabic alike.
Logic is fundamental to philosophical enquiry. The contested question is the human capacity to rationalise, analyse and describe the sensible reality, to understand the ontological structure of the world, and to define the types of entities which exist. The use of this unprecedented synchronic approach will allow us a deeper understanding of the positions, a clear identification of the a priori postulates of the philosophical debates, and a critical evaluation of the arguments used. It provides a unique opportunity to compare the different traditions and highlight the heritage which is common, to stress the specificities of each tradition when tackling philosophical issues and to discover the doctrinal results triggered by their mutual interactions, be they constructive (scholarly exchanges) or polemic (religious controversies).

Project Adaptive Actin Architectures

Call Details Advanced Grant (AdG), LS3, ERC-2016-ADG
Summary Although we have extensive knowledge of many important processes in cell biology, including information on many of the molecules involved and the physical interactions among them, we still do not understand most of the dynamical features that are the essence of living systems. This is particularly true for the actin cytoskeleton, a major component of the internal architecture of eukaryotic cells. In living cells, actin networks constantly assemble and disassemble filaments while maintaining an apparent stable structure, suggesting a perfect balance between the two processes. Such behaviors are called “dynamic steady states”. They confer upon actin networks a high degree of plasticity allowing them to adapt in response to external changes and enable cells to adjust to their environments. Despite their fundamental importance in the regulation of cell physiology, the basic mechanisms that control the coordinated dynamics of co-existing actin networks are poorly understood. In the AAA project, first, we will characterize the parameters that allow the coupling among co-existing actin networks at steady state. In vitro reconstituted systems will be used to control the actin nucleation patterns, the closed volume of the reaction chamber and the physical interaction of the networks. We hope to unravel the mechanism allowing the global coherence of a dynamic actin cytoskeleton. Second, we will use our unique capacity to perform dynamic micropatterning, to add or remove actin nucleation sites in real time, in order to investigate the ability of dynamic networks to adapt to changes and the role of coupled network dynamics in this emergent property. In this part, in vitro experiments will be complemented by the analysis of actin network remodeling in living cells. In the end, our project will provide a comprehensive understanding of how the adaptive response of the cytoskeleton derives from the complex interplay between its biochemical, structural and mechanical properties.

Summary A central problem in developmental biology is to understand how tissues are patterned in time and space - how do identical cells differentiate to form the adult body plan? Patterns often arise from prior asymmetries in developing embryos, but there is also increasing evidence for self-organizing mechanisms that can break the symmetry of an initially homogeneous cell population. These patterning processes are mediated by a small number of signaling molecules, including the TGF-β superfamily members BMP and Nodal. While we have begun to analyze how biophysical properties such as signal diffusion and stability contribute to axis formation and tissue allocation during vertebrate embryogenesis, three key questions remain. First, how does signaling cross-talk control robust patterning in developing tissues? Opposing sources of Nodal and BMP are sufficient to produce secondary zebrafish axes, but it is unclear how the signals interact to orchestrate this mysterious process. Second, how do signaling systems self-organize to pattern tissues in the absence of prior asymmetries? Recent evidence indicates that axis formation in mammalian embryos is independent of maternal and extra-embryonic tissues, but the mechanism underlying this self-organized patterning is unknown. Third, what are the minimal requirements to engineer synthetic self-organizing systems? Our theoretical analyses suggest that self-organizing reaction-diffusion systems are more common and robust than previously thought, but this has so far not been experimentally demonstrated. We will address these questions in zebrafish embryos, mouse embryonic stem cells, and bacterial colonies using a combination of quantitative imaging, optogenetics, mathematical modeling, and synthetic biology. In addition to providing insights into signaling and development, this high-risk/high-gain approach opens exciting new strategies for tissue engineering by providing asymmetric or temporally regulated signaling in organ precursors.

Project The Proceedings of the Ecumenical Councils from Oral Utterance to Manuscript Edition as Evidence for Late Antique Persuasion and Self-Representation Techniques

Summary The Acts of the Ecumenical Councils of Late Antiquity include (purportedly) verbatim minutes of the proceedings, a formal framework and copies of relevant documents which were either (allegedly) read out during the proceedings or which were later attached to the Acts proper. Despite this unusual wealth of documentary evidence, the daunting nature of the Acts demanding multidisciplinary competency, their complex structure with a matryoshka-like nesting of proceedings from different dates, and the stereotype that their contents bear only on Christological niceties have deterred generations of historians from studying them. Only in recent years have their fortunes begun to improve, but this recent research has not always been based on sound principles: the recorded proceedings of the sessions are still often accepted as verbatim minutes. Yet even a superficial reading quickly reveals widespread editorial interference. We must accept that in many cases the Acts will teach us less about the actual debates than about the editors who shaped their presentation. This does not depreciate the Acts’ evidence: on the contrary, they are first-rate material for the rhetoric of persuasion and self-representation. It is possible, in fact, to take the investigation to a deeper level and examine in what manner the oral proceedings were put into writing: several passages in the Acts comment upon the process of note-taking and the work of the shorthand writers. Thus, the main objective of the proposed research project could be described as an attempt to trace the destinies of the Acts’ texts, from the oral utterance to the manuscript texts we have today. This will include the fullest study on ancient transcript techniques to date; a structural analysis of the Acts’ texts with the aim of highlighting edited passages; and a careful comparison of the various editions of the Acts, which survive in Greek, Latin, Syriac and Coptic, in order to detect traces of editorial interference.

Call Details Starting Grant (StG), LS3, ERC-2011-StG_20101109
Summary The cell cortex is a highly dynamic layer of crosslinked actin filaments and myosin molecular motors beneath the cell membrane. It plays a central role in large scale rearrangements that occur inside cells. Many molecular mechanisms contribute to cortex structure and dynamics. However, cell scale physical properties of the cortex are difficult to grasp. This is problematic because for large scale rearrangements inside a cell, such as coherent flow of the cell cortex, it is the cell scale emergent properties that are important for the realization of such events. I will investigate how the actomyosin cytoskeleton behaves at a coarse grained and cellular scale, and will study how this emergent active behaviour is influenced by molecular mechanisms. We will study the cell cortex in the one cell stage C. elegans embryo, which undergoes large scale cortical flow during polarization and cytokinesis. We will combine theory and experiment. We will characterize cortex structure and dynamics with biophysical techniques such as cortical laser ablation and quantitative photobleaching experiments. We will develop and employ novel theoretical approaches to describe the cell scale mechanical behaviour in terms of an active complex fluid. We will utilize genetic approaches to understand how these emergent mechanical properties are influenced by molecular activities. A central goal is to arrive at a coarse grained description of the cortex that can predict future dynamic behaviour from the past structure, which is conceptually similar to how weather forecasting is accomplished. To date, systematic approaches to link molecular scale physical mechanisms to those on cellular scales are missing. This work will open new opportunities for cell biological and cell biophysical research, by providing a methodological approach for bridging scales, for studying emergent and large-scale active mechanical behaviours and linking them to molecular mechanisms.

Call Details Starting Grant (StG), LS3, ERC-2014-STG
Summary Cytokinesis completes cell division by partitioning the contents of the mother cell to the two daughter cells. This process is accomplished through the assembly and constriction of a contractile ring, a complex actomyosin network that remains poorly understood on the molecular level. Research in cytokinesis has overwhelmingly focused on signaling mechanisms that dictate when and where the contractile ring is assembled. By contrast, the research I propose here addresses fundamental questions about the structural and functional properties of the contractile ring itself. We will use the nematode C. elegans to exploit the power of quantitative live imaging assays in an experimentally tractable metazoan organism. The early C. elegans embryo is uniquely suited to the study of the contractile ring, as cells dividing perpendicularly to the imaging plane provide a full end-on view of the contractile ring throughout constriction. This greatly facilitates accurate measurements of constriction kinetics, ring width and thickness, and levels as well as dynamics of fluorescently-tagged contractile ring components. Combining image-based assays with powerful molecular replacement technology for structure-function studies, we will 1) determine the contribution of branched and non-branched actin filament populations to contractile ring formation; 2) explore its ultra-structural organization in collaboration with a world expert in electron microcopy; 3) investigate how the contractile ring network is dynamically remodeled during constriction with the help of a novel laser microsurgery assay that has uncovered a remarkably robust ring repair mechanism; and 4) use a targeted RNAi screen and phenotype profiling to identify new components of actomyosin contractile networks. The results from this interdisciplinary project will significantly enhance our mechanistic understanding of cytokinesis and other cellular processes that involve actomyosin-based contractility.

Summary The mechanism of cell division is conserved in many eukaryotes, from yeast to man. A contractile ring of filamentous actin and myosin II motors generates the force to bisect a mother cell into two daughters. The actomyosin ring is among the most complex cellular machines, comprising over 150 proteins. Understanding how these proteins organize themselves into a functional ring with appropriate contractile properties remains one of the great challenges in cell biology. Efforts to generate a comprehensive understanding of the mechanism of actomyosin ring assembly have been hampered by the lack of structural information on the arrangement of actin, myosin II, and actin modulators in the ring in its native state. Fundamental questions such as how actin filaments are assembled and organized into a ring remain actively debated. This project will investigate key issues pertaining to cytokinesis in the fission yeast Schizosaccharomyces pombe, which divides employing an actomyosin based contractile ring, using the methods of genetics, biochemistry, cellular imaging, DNA origami, genetic code expansion, and click chemistry. Specifically, we will (1) attempt to visualize actin filament assembly in live cells expressing fluorescent actin generated through synthetic biological approaches, including genetic code expansion and click chemistry (2) decipher actin filament polarity in the actomyosin ring using total internal reflection fluorescence microscopy of labelled dimeric and multimeric myosins V and VI generated through DNA origami approaches (3) address when, where, and how actin filaments for cytokinesis are assembled and organized into a ring and (4) reconstitute actin filament and functional actomyosin ring assembly in permeabilized spheroplasts and in supported bilayers. Success in the project will provide major insight into the mechanism of actomyosin ring assembly and illuminate principles behind cytoskeletal self-organization.

Summary "Since 1960, the television industry has undergone successive waves of technological change. Both the methods of programme making and the programmes themselves have changed substantially. The current opening of TV’s vast archives to public and academic use has emphasised the need to explain old programming to new users. Why particular programmes are like they are is not obvious to the contemporary viewer: the prevailing technologies imposed limits and enabled forms that have fallen into disuse. The project will examine the processes of change which gave rise to the particular dominant configurations of technologies for sound and image capture and processing, and some idea of the national and regional variants that existed. It will emphasise the capabilities of the machines in use rather than the process of their invention. The project therefore studies how the technologies of film and tape were implemented; how both broadcasters and individual filmers coped with the conflicting demands of the different machines at their disposal; how new ‘standard ways of doing things’ gradually emerged; and how all of this enabled desired changes in the resultant programmes. The project will produce an overall written account of the principal changes in the technologies in use in broadcast TV since 1960 to the near present. It will offer a theory of technological innovation, and a major case study in the adoption of digital workflow management in production for broadcasting: the so-called ‘tapeless environment’ which is currently being implemented in major organisations. It will offer two historical case studies: a longditudinal study of the evolution of tape-based sound recording and one of the rapid change from 16mm film cutting to digital editing, a process that took less than five years. Reconstructions of the process of working with particular technological arrays will be filmed and will be made available as explanatory material for any online archive of TV material ."

Summary Integrins are transmembrane cell adhesion receptors controlling cell proliferation and migration. Our objective is to gain fundamentally novel mechanistic insight into the emerging new roles of integrins in cancer and to generate a road map of integrin dependent pathways critical in mammary gland development and integrin signalling thus opening new targets for therapeutic interventions. We will combine an in vivo based translational approach with cell and molecular biological studies aiming to identify entirely novel concepts in integrin function using cutting edge techniques and synthetic-biology tools.
The specific objectives are:
1) Integrin inactivation in branching morphogenesis and cancer invasion. Integrins regulate mammary gland development and cancer invasion but the role of integrin inactivating proteins in these processes is currently completely unknown. We will investigate this using genetically modified mice, ex-vivo organoid models and human tissues with the aim to identify beneficial combinational treatments against cancer invasion.
2) Endosomal adhesomes – cross-talk between integrin activity and integrin “inside-in signaling”. We hypothesize that endocytosed active integrins engage in specialized endosomal signaling that governs cell survival especially in cancer. RNAi cell arrays, super-resolution STED imaging and endosomal proteomics will be used to investigate integrin signaling in endosomes.
3) Spatio-temporal co-ordination of adhesion and endocytosis. Several cytosolic proteins compete for integrin binding to regulate activation, endocytosis and recycling. Photoactivatable protein-traps and predefined matrix micropatterns will be employed to mechanistically dissect the spatio-temporal dynamics and hierarchy of their recruitment.
We will employ innovative and unconventional techniques to address three major unanswered questions in the field and significantly advance our understanding of integrin function in development and cancer.

Project Architectural Culture of the Early Modern Eastern Adriatic

Summary During the 15th century, the political process of reducing the Eastern Adriatic, here considered as encompassing what is now littoral of Slovenia, Croatia and Montenegro, to a thin strip of border territories substantially separated from the continental massive to which they belong, reached its conclusion. The insularity of its large natural archipelago, i.e. almost exclusive dependence on the maritime communications, became characteristic even of mainland coastal towns, with lasting consequences. The project explores the impact of this change in the area between 15th and 18th c., focusing on architecture as the most evident materialization of a culture and its transformations. The goal is to examine the architectural culture in question in terms of both consumption and production. Factors such as political and economic consolidation of Venetian and Dubrovnik Republics as well as Habsburg Empire in the area, war and commerce with the Ottomans, but also the quick spread of revival of antiquity and the Catholic Revival, all fuelled the need for architectural creation with certain functional and symbolic characteristics, setting the cultural standards. On the other hand, the economics of production of architecture consisted of interrelated systems of the provision of materials (esp. Istrian stone) and organisation of construction sites, which, given the ease of the sea transport, resulted in an active market for architectural goods. This approach will provide an original contribution to the understanding of cultural practices that not only produced specific buildings, the most significant among which are now listed as World Heritage sites but also put into circulation ancient and modern models, techniques and materials for a European-wide audience. Moreover, it will investigate the trans-border and trans-confessional character of the architectural market, thus providing an innovative model for a study of such phenomena across Europe.
Summary
During the 15th century, the political process of reducing the Eastern Adriatic, here considered as encompassing what is now littoral of Slovenia, Croatia and Montenegro, to a thin strip of border territories substantially separated from the continental massive to which they belong, reached its conclusion. The insularity of its large natural archipelago, i.e. almost exclusive dependence on the maritime communications, became characteristic even of mainland coastal towns, with lasting consequences. The project explores the impact of this change in the area between 15th and 18th c., focusing on architecture as the most evident materialization of a culture and its transformations. The goal is to examine the architectural culture in question in terms of both consumption and production. Factors such as political and economic consolidation of Venetian and Dubrovnik Republics as well as Habsburg Empire in the area, war and commerce with the Ottomans, but also the quick spread of revival of antiquity and the Catholic Revival, all fuelled the need for architectural creation with certain functional and symbolic characteristics, setting the cultural standards. On the other hand, the economics of production of architecture consisted of interrelated systems of the provision of materials (esp. Istrian stone) and organisation of construction sites, which, given the ease of the sea transport, resulted in an active market for architectural goods. This approach will provide an original contribution to the understanding of cultural practices that not only produced specific buildings, the most significant among which are now listed as World Heritage sites but also put into circulation ancient and modern models, techniques and materials for a European-wide audience. Moreover, it will investigate the trans-border and trans-confessional character of the architectural market, thus providing an innovative model for a study of such phenomena across Europe.
