My contribution is part of a new work in progress exploring the sense of touch in Italian Renaissance anatomy. Through regular experiences of surgery and dissections, anatomists/surgeons refined their sense of touch and developed a particularly acute ability to feel and act upon bodily parts and substances. By looking at the dissecting body—the hand, fingers, and skin of anatomists/surgeons—this paper will examine the body dissected—especially its bones, muscles, and surfaces—highlighting the multiple layers of the sense of touch in the Renaissance.

Les tombes des papes Médicis Léon X et Clément VII érigées dans l’église de Santa Maria sopra Minerva à Rome sont sans doute l’une des entreprises artistiques les plus ambitieuses menées après le sac de la ville pontificale en 1527. Une abondante documentation nous permet, par chance, de connaître les détails de cette commande prestigieuse, résultat des volontés testamentaires de Clément VII, et surtout d’en identifier un des principaux acteurs : Baldassarre Turini, membre influent de la curie romaine et riche mécène. Fort d’un réseau étendu au sein du monde artistique romain, il devient naturellement l’interlocuteur privilégié des artistes à l’œuvre sur ce chantier et le relais des exécuteurs testamentaires de Clément VII. C’est ainsi qu’il entre en conflit direct avec le sculpteur des tombes, l’impétueux Baccio Bandinelli, ce qui aura des conséquences irréversibles pour l’artiste. À la lumière des lettres échangées par le prélat, qui seront croisées au précieux témoignage de l’historiographe Giorgio Vasari, cette conférence sera l’occasion de révéler le rôle crucial joué par Turini lors de cette commande, et par là même, de préciser ses responsabilités d’intermédiaire artistique au service de la puissante famille Médicis.

Among all possible spin states, spin-coherent states are the most classical because the spin expectation value in these states yields a vector of maximal norm pointing in a well defined direction. In contrast, anticoherent spin state to order t are such that <(J.n)^k> is independent of the unit vector n for k = 1, ..., t [1]. By construction, coherent and anticoherent spin states are at both ends of the spectrum of classicality. The aim of this work is to position all possible spin states on such a spectrum, that is to provide measures of anticoherence. To this aim, we introduce an axiomatic definition of anticoherence measures to any order t. In particular, we show that the total variance of a pure spin state, first introduced in [2] can be used to define a measure of anticoherence to order 1. We describe a systematic way of constructing anticoherence measures to any order that relies on the mapping between spin-j states and symmetric states of N = 2j spin-1/2. In particular, we exploit the fact that anticoherent spin states to order t have maximally mixed t-spin-1/2 reduced density matrices in the symmetric subspace [3]. [1] J. Zimba, Electron. J. Theor.

Arrays of qubits encoded in the ground state manifold of trapped neutral atoms appear as a promising platform for the realisation of a scalable quantum computer. Indeed, such physical qubits have a long coherence time and allow for high-fidelity single-qubit operations [1]. In such a platform, entangling two-qubit gates can be implemented by exploiting the Rydberg-blockade mechanism to produce a phase shift or a flip of the state of a target atom conditioned on the state of a control atom [2]. However, because dipole-dipole interactions fall off rapidly with the interatomic distance, such entangling gates based on Rydberg-blockade are impractical between distant qubits. In this work, we propose a protocol to implement long-range Rydberg-blockade gates (CZ or CNot) using auxillary non-coding atoms to transfer the Rydberg excitation from the control to the target qubit. The dependence of the fidelity on the number of auxillary atoms, the blockade strength and the decay rates of the Rydberg states are determined. When compared to a sequential application of nearest neighbours entangling gates, our protocol leads to a larger fidelity and a reduction of the overall gate duration (which scales linearly with the number of auxillary atoms).

Generally, projects are analyzed when they still ongoing or just at the end. Similarly, the analysis of power issues is generally being focused, in projects cases, on the problems of coordination and conflicting relations and their foundations. This doctoral thesis goes a little at the antipodes of these studies. First, it questions closed projects. Afterwards, even if it integrates the conflicting vision of power because of the closed nature of the projects, it additionally uses an alternative approach of power based on "powers of action". Concretely, it takes interest in the projects that the Dutch and Belgian agencies have carried out in the municipality of Cobly in the North-West of Benin. To do so, it closely looks at the participation systems and the appropriation mechanisms designed and implemented in the constituted arenas. It also questions the intervention frameworks and the projects publicizing process. Plus, it seeks to know how the beneficiaries use, the supports that directly reach them or they "hijack", for their empowerment. In doing so, it has taken the option to refocus reflection on the causes of problems and the actors really concerned. The methodological approach used for this research is a mix of sociohistory and biographical approach. It clearly appears, from the results and analyzes made, that the forms of formalized partnerships, the use of participation and the otherness of introduced clustering models have led to "negative" organizational governance, approximate results and differential appropriation's. The various mediated powers and the feelings they have left at actors’ level, have played a great role in these objectified situations. Socio-historical literature requires that the stakes associated with the interactions made possible by the projects, the participation modalities and the fundamentals of POs governance been co-constructed. Similarly, it asks that the learning systems and the capacities of the beneficiaries be constantly put into perspective through oriented decision-making processes. This literature also reveals that the scales generally used to evaluate the impact of projects have always rendered elusive, not only their real effects on the "Powers to act" of the beneficiaries, but also and above all, the effects of the powers they reinforce, on the trajectories of life of beneficiaries.

Bovine Leukemia Virus (BLV) is a deltaretrovirus closely related to the Human T-cell leukemia virus-1 (HTLV-1). The natural host of BLV is cattle and much like the case of HTLV-1 in humans, about ~5% of infected individuals develop leukemia/lymphoma following a long period of asymptomatic infection (~7 years in cattle, several decades in human). Experimental infection of sheep with BLV results in a reduced latency period (2 years on average), making for an attractive cancer model. A further advantage of the BLV system is that it is possible to infect sheep via injection of a cloned provirus, facilitating the mutation of specific parts of the viral genome to examine the function of viral products in vivo. Like HTLV-1, the BLV mRNAs/proteins are transcribed from the viral 5’ long terminal repeat (LTR), a region rich in regulatory elements. It was previously believed that the BLV provirus was transcriptionally silent in tumors, however we identified a cluster of five abundantly expressed non-canonical RNA polymerase III dependent microRNAs (miRNAs) encoded by BLV (Rosewick et al., PNAS 2013). In addition, using RNA sequencing we recently discovered viral antisense transcripts originating in the 3' Long Terminal Repeat (LTR) of the BLV provirus (Durkin et al., Retrovirology 2016) . While 5'LTR dependent transcription is absent in malignant cells, both the viral miRNAs and the antisense transcripts are expressed in all BLV induced leukemic and pre-leukemic samples examined to date, pointing to a vital role in the life cycle of the virus and a critical function in cellular transformation.
