Computational Electromagnetics (CEM) is the scientific field at the origin of all new modeling and simulation tools required by the constantly arising design challenges of emerging and future technologies in applied electromagnetics. As in many other technological fields, however, the trend in all emerging technologies in electromagnetic engineering is going towards miniaturized, higher density and multi-scale scenarios. Computationally speaking this translates in the steep increase of the number of degrees of freedom. Given that the design cost (the cost of a multi-right-hand side problem dominated by matrix inversion) can scale as badly as cubically with these degrees of freedom, this fact, as pointed out by many, will sensibly compromise the practical impact of CEM on future and emerging technologies. For this reason, the CEM scientific community has been looking for years for a FFT-like paradigm shift: a dynamic fast direct solver providing a design cost that would scale only linearly with the degrees of freedom. Such a fast solver is considered today a Holy Grail of the discipline. The Grand Challenge of 321 will be to tackle this Holy Grail in Computational Electromagnetics by investigating a dynamic Fast Direct Solver for Maxwell Problems that would run in a linear-instead-of-cubic complexity for an arbitrary number and configuration of degrees of freedom. The failure of all previous attempts will be overcome by a game-changing transformation of the CEM classical problem that will leverage on a recent breakthrough of the PI. Starting from this, the project will investigate an entire new paradigm for impacting algorithms to achieve this grand challenge. The impact of the FFT’s quadratic-to-linear paradigm shift shows how computational complexity reductions can be groundbreaking on applications. The cubic-to-linear paradigm shift, which the 321 project will aim for, will have such a rupturing impact on electromagnetic science and technology.

Which brain mechanisms are responsible for the faith of the memories we make with age, whether they wither or stay, and in what form? Episodic memory function does decline with age. While this decline can have multiple causes, research has focused almost entirely on encoding and retrieval processes, largely ignoring a third critical process– consolidation. The objective of AgeConsolidate is to provide this missing link, by combining novel experimental cognitive paradigms with neuroimaging in a longitudinal large-scale attempt to directly test how age-related changes in consolidation processes in the brain impact episodic memory decline. The ambitious aims of the present proposal are two-fold: (1) Use recent advances in memory consolidation theory to achieve an elaborate model of episodic memory deficits in aging (2) Use aging as a model to uncover how structural and functional brain changes affect episodic memory consolidation in general The novelty of the project lies in the synthesis of recent methodological advances and theoretical models for episodic memory consolidation to explain age-related decline, by employing a unique combination of a range of different techniques and approaches. This is ground-breaking, in that it aims at taking our understanding of the brain processes underlying episodic memory decline in aging to a new level, while at the same time advancing our theoretical understanding of how episodic memories are consolidated in the human brain. To obtain this outcome, I will test the main hypothesis of the project: Brain processes of episodic memory consolidation are less effective in older adults, and this can account for a significant portion of the episodic memory decline in aging. This will be answered by six secondary hypotheses, with 1-3 experiments or tasks designated to address each hypothesis, focusing on functional and structural MRI, positron emission tomography data and sleep experiments to target consolidation from different angles.

Alfonsine astronomy is arguably among the first European scientific achievements. It shaped a scene for actors like Regiomontanus or Copernicus. There is however little detailed historical analysis encompassing its development in its full breadth. ALFA addresses this issue by studying tables, instruments, mathematical and theoretical texts in a methodologically innovative way relying on approaches from the history of manuscript cultures, history of mathematics, and history of astronomy. ALFA integrates these approaches not only to benefit from different perspectives but also to build new questions from their interactions. For instance the analysis of mathematical practices in astral sciences manuscripts induces new ways to analyse the documents and to think about astronomical questions. Relying on these approaches the main objectives of ALFA are thus to: - Retrace the development of the corpus of Alfonsine texts from its origin in the second half of the 13th century to the end of the 15th century by following, on the manuscript level, the milieus fostering it; - Analyse the Alfonsine astronomers’ practices, their relations to mathematics, to the natural world, to proofs and justification, their intellectual context and audiences; - Build a meaningful narrative showing how astronomers in different milieus with diverse practices shaped, also from Arabic materials, an original scientific scene in Europe. ALFA will shed new light on the intellectual history of the late medieval period as a whole and produce a better understanding of its relations to related scientific periods in Europe and beyond. It will also produce methodological breakthroughs impacting the ways history of knowledge is practiced outside the field of ancient and medieval sciences. Efforts will be devoted to bring these results not only to the relevant scholarly communities but also to a wider audience as a resource in the public debates around science, knowledge and culture.

This interdisciplinary project investigates the transformation of Shii Islam in the Middle East and Europe since the 1950s. The project examines the formation of modern Shii communal identities and the role Shii clerical authorities and their transnational networks have played in their religio-political mobilisation. The volatile situation post-Arab Spring, the rise of militant movements such as ISIS and the sectarianisation of geopolitical conflicts in the Middle East have intensified efforts to forge distinct Shii communal identities and to conceive Shii Muslims as part of an alternative umma (Islamic community). The project focusses on Iran, Iraq and significant but unexplored diasporic links to Syria, Kuwait and Britain. In response to the rise of modern nation-states in the Middle East, Shii clerical authorities resorted to a wide range of activities: (a) articulating intellectual responses to the ideologies underpinning modern Middle Eastern nation-states, (b) forming political parties and other platforms of socio-political activism and (c) using various forms of cultural production by systematising and promoting Shii ritual practices and utilising visual art, poetry and new media. The project yields a perspectival shift on the factors that led to Shii communal mobilisation by: - Analysing unacknowledged intellectual responses of Shii clerical authorities to the secular or sectarian ideologies of post-colonial nation-states and to the current sectarianisation of geopolitics in the Middle East. - Emphasising the central role of diasporic networks in the Middle East and Europe in mobilising Shii communities and in influencing discourses and agendas of clerical authorities based in Iraq and Iran. - Exploring new modes of cultural production in the form of a modern Shii aesthetics articulated in ritual practices, visual art, poetry and new media and thus creating a more holistic narrative on Shii religio-political mobilisation.
