ERC FUNDED PROJECTS

This long-term research project is based on the data-mining of the Llibres d'Esposalles conserved at the Archives of the Barcelona Cathedral, an extraordinary data source comprising 244 books of marriage licenses records. It covers about 550.000 unions from over 250 parishes of the Diocese between 1451 and 1905. Its impeccable conservation is a miracle in a region where parish archives have undergone massive destruction. The books include data on the tax posed on each couple depending on their social class, on an eight-tiered scale. These data allow for research on multiple aspects of demographic research, especially on the very long run, such as: population estimates, marriage dynamics, cycles, and indirect estimations for fertility, migration and survival, as well as socio-economic studies related to social homogamy, social mobility, and transmission of social and occupational position. Being continuous over five centuries, the source constitutes a unique instrument to study the dynamics of population distribution, the expansion of the city of Barcelona and the constitution of its metropolitan area, as well as the chronology and the geography in the constitution of new social classes. To this end, a digital library and a database, the Barcelona Historical Marriages Database (BHiMaD), are to be created and completed. An ERC-AG will help doing so while undertaking the research analysis of the database in parallel. The research team, at the U. Autònoma de Barcelona, involves researchers from the Center for Demo-graphic Studies and the Computer Vision Center experts in historical databases and computer-aided recognition of ancient manuscripts. 5CofM will serve the preservation of the original “Llibres d’Esposalles” and unlock the full potential embedded in the collection.

"During the last decade, a strikingly successful cosmological concordance model has been established. With only six free parameters, nearly all observables, comprising millions of data points, may be fitted with outstanding precision. However, in this beautiful picture a few ""blemishes"" have turned up, apparently not consistent with the standard model: While the model predicts that the universe is isotropic (i.e., looks the same in all directions) and homogeneous (i.e., the statistical properties are the same everywhere), subtle hints of the contrary are now seen. For instance, peculiar preferred directions and correlations are observed in the cosmic microwave background; some studies considering nearby galaxies suggest the existence of anomalous large-scale cosmic flows; a study of distant quasars hints towards unexpected large-scale correlations. All of these reports are individually highly intriguing, and together they hint toward a more complicated and interesting universe than previously imagined -- but none of the reports can be considered decisive. One major obstacle in many cases has been the relatively poor data quality. This is currently about to change, as the next generation of new and far more powerful experiments are coming online. Of special interest to me are Planck, an ESA-funded CMB satellite currently taking data; QUIET, a ground-based CMB polarization experiment located in Chile; and various large-scale structure (LSS) data sets, such as the SDSS and 2dF surveys, and in the future Euclid, a proposed galaxy survey satellite also funded by ESA. By combining the world s best data from both CMB and LSS measurements, I will in the proposed project attempt to settle this question: Is our universe really anisotropic? Or are these recent claims only the results of systematic errors or statistical flukes? If the claims turn out to hold against this tide of new and high-quality data, then cosmology as a whole may need to be re-written."

Spectroscopic binary stars (SB2s) and in particular spectroscopic eclipsing binaries are one of the most useful objects in astrophysics. Their photometric and spectroscopic observations allow one to determine basic parameters of stars and carry out a wide range of tests of stellar structure, evolution and dynamics. Perhaps somewhat surprisingly, they can also contribute to our understanding of the formation and evolution of (extrasolar) planets. We will study eclipsing binary stars by combining the classic - stellar astronomy - and the modern - extrasolar planets - subjects into a cutting edge project. We propose to search for and subsequently characterize circumbinary planets around ~350 eclipsing SB2s using our own novel cutting edge radial velocity technique for binary stars and a modern version of the photometry based eclipse timing of eclipsing binary stars employing 0.5-m robotic telescopes. We will also derive basic parameters of up to ~700 stars (~350 binaries) with an unprecedented precision. In particular for about 50% of our sample we expect to deliver masses of the components with an accuracy ~10-100 times better than the current state of the art. Our project will provide unique constraints for the theories of planet formation and evolution and an unprecedented in quality set of the basic parameters of stars to test the theories of the stellar structure and evolution.

The introduction of minimally invasive surgery in the 1980’s created a paradigm shift in surgical procedures. Health care is now in a position to make a more dramatic leap by integrating newly developed wireless microrobotic technologies with nanomedicine to perform precisely targeted, localized endoluminal techniques. Devices capable of entering the human body through natural orifices or small incisions to deliver drugs, perform diagnostic procedures, and excise and repair tissue will be used. These new procedures will result in less trauma to the patient and faster recovery times, and will enable new therapies that have not yet been conceived. In order to realize this, many new technologies must be developed and synergistically integrated, and medical therapies for which the technology will prove successful must be aggressively pursued. This proposed project will result in the realization of animal trials in which wireless microrobotic devices will be used to investigate a variety of extremely delicate ophthalmic therapies. The therapies to be pursued include the delivery of tissue plasminogen activator (t-PA) to blocked retinal veins, the peeling of epiretinal membranes from the retina, and the development of diagnostic procedures based on mapping oxygen concentration at the vitreous-retina interface. With successful animal trials, a path to human trials and commercialization will follow. Clearly, many systems in the body have the potential to benefit from the endoluminal technologies that this project considers, including the digestive system, the circulatory system, the urinary system, the central nervous system, the respiratory system, the female reproductive system and even the fetus. Microrobotic retinal therapies will greatly illuminate the potential that the integration of microrobotics and nanomedicine holds for society, and greatly accelerate this trend in Europe.

Thanks to the recent advances in mapping brain activation during task performance using functional Magnetic Resonance Imaging (i.e., studying the brain in action), it is now possible to study one of the oldest questions in psychology: how the development of neural circuitry underlies the development of cognition and emotion. The ‘Storm and Stress’ of adolescence, a period during which adolescents develop cognitively with great speed but are also risk-takers and sensitive to opinions of their peer group, has puzzled scientists for centuries. New technologies of brain mapping have the potential to shed new light on the mystery of adolescence. The approach proposed here concerns the investigation of brain regions which underlie developmental changes in cognitive, emotional and social-emotional functions over the course of child and adolescent development. For this purpose I will measure functional brain development longitudinally across the age range 8-20 years by using a combined cross-sectional longitudinal design including 240 participants. Participants will take part in two testing sessions over a four-year-period in order to track the within-subject time courses of functional brain development for cognitive, emotional and social-emotional functions and to understand how these functions develop relative to each other in the same individuals, using multilevel models for change. The cross-sectional longitudinal assessment of cognitive, emotional and social-emotional functional brain development in relation to brain structure and hormone levels is unique in the international field and has the potential to provide new explanations for old questions. The application of brain mapping combined with multilevel models for change is original, and allows for the examination of developmental trajectories rather than age comparisons. An integrative mapping (i.e., combined with task performance and with biological markers) of functional brain development is important not only for theory development, but also for understanding how children learn new tasks and participate in a complex social world, and eventually to tailor educational programs to the needs of children.

This project will be aimed at obtaining a deeper insight into the physical processes taking place in astrophysical magnetized plasmas. To study these scenarios I will employ different numerical codes as virtual tools that enable me to experiment on computers (virtual labs) with distinct initial and boundary conditions. Among the kind of sources I am interested to consider, I outline the following: Gamma-Ray Bursts (GRBs), extragalactic jets from Active Galactic Nuclei (AGN), magnetars and collapsing stellar cores. A number of important questions are still open regarding the fundamental properties of these astrophysical sources (e.g., collimation, acceleration mechanism, composition, high-energy emission, gravitational wave signature). Additionally, there are analytical issues on the formalism in relativistic dynamics not resolved yet, e.g., the covariant extension of resistive magnetohydrodynamics (MHD). All these problems are so complex that only a computational approach is feasible. I plan to study them by means of relativistic and Newtonian MHD numerical simulations. A principal focus of the project will be to assess the relevance of magnetic fields in the generation, collimation and ulterior propagation of relativistic jets from the GRB progenitors and from AGNs. More generally, I will pursue the goal of understanding the process of amplification of seed magnetic fields until they become dynamically relevant, e.g., using semi-global and local simulations of representative boxes of collapsed stellar cores. A big emphasis will be put on including all the relevant microphysics (e.g. neutrino physics), non-ideal effects (particularly, reconnection physics) and energy transport due to neutrinos and photons to account for the relevant processes in the former systems. A milestone of this project will be to end up with a numerical tool that enables us to deal with General Relativistic Radiation Magnetohydrodynamics problems in Astrophysics.

Nowadays human intellectual product is increasingly produced and disseminated solely in digital form. The capability of digital data for effortless reproduction and transfer has lead to a true revolution that impacts every aspect of human creativity. Nevertheless, as with every technological revolution, this digital media revolution comes with a dark side that, if left unaddressed, it will limit its impact and may counter its potential advantages. In particular, the way we produce and disseminate digital content today does not lend itself to controlling the way data move and change. It turns out that the power of being digital can be a double-edged sword: the ease of production, dissemination and editing also implies the ease of misappropriation, plagiarism and improper modification. To counter the above problems, the proposed research activity will focus on the development of a new generation of enabling cryptographic technologies that have the power to facilitate the appropriate controls for data movement. Using the techniques developed in this project it will be feasible to build digital content distribution systems where content producers will have the full possible control on the dissemination of their intellectual product, while at the same time the rights of the end-users in terms of privacy and fair use can be preserved. The PI is uniquely qualified to carry out the proposed research activity as he has extensive prior experience in making innovations in the area of digital content distribution as well as in the management of research projects. As part of the project activities, the PI will establish the CODAMODA laboratory in the University of Athens and will seek opportunities for technology transfer and interdisciplinary work with the legal science community.

Networks have been studied in depth for several decades, but one aspect has received little attention: Interference. Most networks use clever algorithms to avoid interference, and this strategy has proved effective for traditional supply-chain or wired communication networks. However, the emergence of wireless networks revealed that simply avoiding interference leads to significant performance loss. A wealth of cooperative communication strategies have recently been developed to address this issue. Two fundamental roadblocks are emerging: First, it is ultimately unclear how to integrate cooperative techniques into the larger fabric of networks (short of case-by-case redesigns); and second, the lack of source/channel separation in networks (i.e., more bits do not imply better end-to-end signal quality) calls for ever more specialized cooperative techniques. This proposal advocates a new understanding of interference as computation: Interference garbles together inputs to produce an output. This can be thought of as a certain computation, perhaps subject to noise or other stochastic effects. The proposed work will develop strategies that permit to exploit this computational potential. Building on these ``computation codes,'' an enhanced physical layer is proposed: Rather than only forwarding bits, the revised physical layer can also forward functions from several transmitting nodes to a receiver, much more efficiently than the full information. Near-seamless integration into the fabric of existing network architectures is thus possible, providing a solution for the first roadblock. In response to the second roadblock, computation codes suggest new computational primitives as fundamental currencies of information.

Current IT research does not respond to the world's multi-cultural reality. It could be argued that we are imposing the paradigms of our market-driven western culture also on IT and that current IT research results will only facilitate the access of a small part of the world’s information to a small part of the world's population. Most IT research is being carried out with a western centred approach and as a result, our data models, cognition models, user models, interaction models, ontologies, … are all culturally biased. This fact is quite evident in music information research, since, despite the world's richness in musical cultures, most of the research is centred on CDs and metadata of our western commercial music. CompMusic wants to break this huge research bias. By approaching musical information modelling from a multicultural perspective it aims at advancing our state of the art while facilitating the discovery and reuse of the music produced outside the western commercial context. But the development of computational models to address the world’s music information richness cannot be done from the West looking out; we have to involve researchers and musical experts immersed in the different cultures. Their contribution is fundamental to develop the appropriate multicultural musicological and cognitive frameworks from which we should then carry our research on finding appropriate musical features, ontologies, data representations, user interfaces and user centred approaches. CompMusic will investigate some of the most consolidated non-western classical music traditions, Indian (hindustani, carnatic), Turkish-Arab (ottoman, andalusian), and Chinese (han), developing the needed computational models to bring their music into the current globalized information framework. Using these music cultures as case studies, cultures that are alive and have a strong influence in current society, we can develop rich information models that can take advantage of the existing information coming from musicological and cultural studies, from mature performance practice traditions and from active social contexts. With this approach we aim at challenging the current western centred information paradigms, advance our IT research, and contribute to our rich multicultural society.
