At the time of the Great Western Schism, the dukes of Valois d’Anjou tried several times to establish themselves in the Kingdom of Naples, vassal to the Holy See. With the support of the Avignon popes, they received regular financial aid in addition to the concession of the royal title. If this recognition allowed them to legitimize their war of conquest and thereby reconcile the backing of many Neapolitan feudal lords, it came with the duty of throwing the pope in Rome under the throne of Saint Peter. However, in spite of promises made in this guise, the Dukes of Anjou showed little inclination to direct its army toward Lazio. In sum, if the justification at the basis of all of the Angevine military campaigns was indispensable for their existence, it was of little factual consequence. [less ▲]

In the past few years there has been an impressive number of proposals for application-specific overlays or peerto-peer networks. However the procedure to bootstrap peers in those networks has remained an under-researched topic, typically left as an implementation detail. In this paper, we first study the performance of history lists, a common decentralised bootstrap mechanism used in P2P applications. We then investigate how some lightweight network support, such as Ephemeral State, could help build a P2P application that would not depend on any centralised mechanism to discover other peers.

Hearing requires an optimal afferent innervation of sensory hair cells by spiral ganglion neurons in the cochlea. Here we report that complementary expression of ephrin-A5 in hair cells and EphA4 receptor among spiral ganglion neuron populations controls the targeting of type I and type II afferent fibres to inner and outer hair cells, respectively. In the absence of ephrin-A5 or EphA4 forward signalling, a subset of type I projections aberrantly overshoot the inner hair cell layer and invade the outer hair cell area. Lack of type I afferent synapses impairs neurotransmission from inner hair cells to the auditory nerve. By contrast, radial shift of type I projections coincides with a gain of presynaptic ribbons that could enhance the afferent signalling from outer hair cells. Ephexin-1, cofilin and myosin light chain kinase act downstream of EphA4 to induce type I spiral ganglion neuron growth cone collapse. Our findings constitute the first identification of an Eph/ephrin-mediated mutual repulsion mechanism responsible for specific sorting of auditory projections in the cochlea. [less ▲]

Interactions between the Eph receptor tyrosine kinase and ephrin ligands transduce short-range signals regulating axon pathfinding, development of the cardiovascular system, as well as migration and spreading of neuronal and non-neuronal cells. Some of these effects are believed to be mediated by alterations in actin dynamics. The members of the small Rho GTPase family elicit various effects on actin structures and are probably involved in Eph receptor-induced actin modulation. EphrinA1 is proposed to contribute to angiogenesis as it is strongly expressed at sites of neovascularization. Moreover, angiogenic factors induce the expression of ephrinA1 in endothelial cells. In this study, using rat vascular smooth muscle cells (VSMCs), we investigated the contribution of the small Rho GTPases in ephrinA1-induced integrin inactivation. EphrinA1 did not significantly affect early adhesion of VSMCs on purified laminin or fibronectin, but strongly impaired cell spreading. The Rho kinase inhibitor Y-27632 partly reversed the ephrinA1 effect, suggesting involvement of Rho in this model. However, inhibition of RhoA synthesis with short interfering (si)RNA had a modest effect, suggesting that RhoA plays a limited role in ephrinA1-mediated inhibition of spreading in VSMCs. The ephrinA1-mediated morphological alterations correlated with inhibition of Rac1 and p21-activated kinase 1 (PAK1) activity, and were antagonized by the expression of a constitutively active Rac mutant. Moreover, repression of Rac1 synthesis with siRNA amplifies the ephrinA1-induced inhibition of spreading. Finally, sphingosine-1-phosphate (S1P), a lipid mediator known to inhibit Rac activation in VSMCs amplifies the ephrinA1 effect. In conclusion, our results emphasize the role of the Rac/PAK pathway in ephrinA1-mediated inhibition of spreading. In this way, ephrinA1, alone or in synergy with S1P, can participate in blood vessel destabilization, a prerequisite for angiogenesis. [less ▲]

My thesis is based on the premise that verse-novels occupy a marginalised and contested position in contemporary literature: as they tread the generic boundaries of poetry and prose writing, they are always marked by their incongruous nature. This makes for uncomfortable reading as expectations are disrupted and undermined, and, for the poet, the adoption of the verse-novel form becomes both a risky and consciously political move. Each of the verse-novels that I consider is self-conscious of its anomalous generic affiliations and utilises them in order to replicate the postcolonial politics of the text. These texts all engage with the verse-novel form in different ways and draw attention to its problematic and marginal nature. This is used to highlight their postcolonial nature, as they are all concerned with matters of racial and national identity in a world where these categories are complicated. The commonality in these works is their relationships with epic form, in this thesis I identify this as a post-epic mode of writing. My study is based on the relationship between poetic form and postcolonial critique; it focuses upon three texts: the Australian poet Les Murray’s Fredy Neptune, the Canadian poet Anne Carson’s Autobiography of Red, and British writer Bernardine Evaristo’s The Emperor’s Babe. These texts and their authors call for a reconsideration of postcolonialism; this is both demonstrative of a conceptual shift towards global notions of identity, whilst also being problematic in terms of the political commitment of the texts. Each of these works demonstrates an awareness of the contradictory nature of their positions as they shy away from utopian visions. In line with this, my aim is to demonstrate the way in which the self-reflexive employment of experimental poetry compliments an engagement with the transformative aspect of contemporary postcolonial politics.

L'épicéa commun (Picea Abies KARST) est de loin l'essence la mieux représentée au sein de la forêt wallonne. Aussi, dans une perspective de valorisation de la production ligneuse des pessières, est-il essentiel de disposer d'informations aussi complètes que possible sur les caractéristiques des peuplements, sur leur accroissement et leurs possibilités futures d'exploitation ainsi que sur la qualité technologique du bois d'épicéa. Des recherches menées depuis plusieurs années à la Faculté des Sciences Agronomiques de Gembloux dans le domaine de la production des essences résineuses, des inventaires forestiers et de la valorisation des produits ligneux permettent aujourd'hui d'apporter des éléments de réponse à la plupart de ces questions. Nous caractériserons d'abord l'état actuel des peuplements d'épicéa en considérant, d'une part, les surfaces occupées selon divers critères et, d'autre part, les volumes sur pied (paragraphe 2). Nous tenterons ensuite, par simulation, de prévoir la production à venir des peuplements d'ici 20 ans et la quantité annuelle moyenne de matériel exploitable selon deux "stratégies" de traitement (paragraphe 2). Nous présenterons enfin, les premiers résultats d'une étude fouillée portant sur les principales propriétés technologiques du bois d'épicéa (paragraphe 3). [less ▲]

L’utilisation d’épithètes nombreuses est un des traits caractéristiques des Hymnes orphiques. Si elles contribuent toutes à définir les contours des divinités invoquées dans ces hymnes, elles présentent cependant une certaine diversité d’emploi ; certaines peuvent ainsi être identifiées comme étant – ou faisant référence à – des épiclèses, i.e. des épithètes désignant chacune une entité divine honorée dans un lieu donné. Dans cette optique, la mise en parallèle des Hymnes orphiques avec d’autres sources (épigraphiques notamment), mettant en lumière de possibles allusions, à travers certaines dénominations divines, à des cultes attestés par ailleurs, peut apporter des précisions sur le contexte religieux dans lequel s’inscrivent ces hymnes. Étant la mieux représentée dans le recueil des Hymnes orphiques, la figure de Dionysos constitue le principal fil conducteur de cette enquête. [less ▲]

The Barabasi-Albert (BA) model with finite-precision preferential attachment is used to build a wide range of network structures. Spreading epidemics and collective dynamics are investigated on such complex networks. Numerical simulations reveal a transition from an exponential scaling to a power law distribution of link numbers per node along with the increase of the tuning parameter ω. The collective synchronization induced by Susceptible- Infected-Recovered-Susceptible (SIRS) epidemiological process is shown to depend on the topological structure of the network. [less ▲]

« You know where this comes from, shaking hands? It was a way of showing a stranger you weren't carrying a weapon in the old days. » Contagion, Steven Soderbergh, 2011 For decades film directors, inspired by numerous novelists, have exploited the epidemic in various ways: as a general historical context to tell another story (Isle of the Dead, Robson, 1945), as a medical topic at the heart of an investigation (Medical Investigation, Horwitch, 2004), or as a process allowing the proliferation of zombies (Resident Evil, Anderson, 2000) or even vampires (Daybreakers, Spierig, 2010). This work aims at theorising a fascinating and surprising topic – which goes as far as haunting public restrooms with the “Stop Germs: Wash Your Hands” signs – and to offer an overview of films that are very present on our screens and yet absent from scholarly works about cinema. By combining the analysis of photography with that of narrative, this research tries to address issues which may seem, at first sight, plain and transparent (showing the epidemic is showing contaminated individuals) but prove to be, in practice, much more complex (how can contamination be represented since this microscopic phenomenon is invisible to the eye?). The developed method leans on science and the ties between epidemic, contagion and contamination in order to establish an approach going from the more general (epidemic, which belongs to the global and is illustrated as far as the film’s synopsis) to the more particular (contamination, which falls under the interpersonal and is represented only in precise sequence of the film). Beyond questions about cinema or narrative in the strict sense, this final dissertation aims at exploring the other side of epidemic: the collective imaginary it creates. Indeed, the way cinema represents these phenomena indicates a certain conception of epidemic, which spreads from a film to the other, from a viewer to the other. [less ▲]

Elderly people in nursing home communities are vulnerable to contagious infections, including the influenza virus. Systematic anti-influenza vaccination is an important preventive measure; however, vaccination does not provide absolute protection. We report an outbreak of influenza A infection in a well-vaccinated nursing home population. Several factors can facilitate the occurrence of this type of outbreak. This report mainly addresses the discrepancy between the circulating viral strain and strains present in the recommended vaccine. [less ▲]
