Variabilité pluviométrique et dynamique hydro-sédimentaire du bassin versant du complexe fluvio-lagunaire Mono-Ahémé-Couffo (Afrique de l'ouest)
2010
This thesis aims to highlight the relationship between climate and water balance process on the basin of the complex river-lagoon Mono-Aheme-Couffo. A better analysis rain/flow is made using rainfall spatialization from interpolation, taking into account altitude and geographical coordinates of hydrometeorological stations. Also, pluvio-hydrological variability and surface states dynamics impacts on sedimentation are examined. Runoff variability and sediment dynamics in the watershed Mono-Aheme-Couffo over the period 1961-2000 in a context of integrated water resources management (IWRM) were analyzed according to the rainfall depths, effects of water releases from the Nangbeto dam operation…
Brain lateralization probed by water diffusion at the atomic to micrometric scale
2019
International audience; Combined neutron scattering and diffusion nuclear magnetic resonance experiments have been used to reveal significant interregional asymmetries (lateralization) in bovine brain hemispheres in terms of myelin arrangement and water dynamics at micron to atomic scales. Thicker myelin sheaths were found in the left hemisphere using neutron diffraction. 4.7 T dMRI and quasi-elastic neutron experiments highlighted significant differences in the properties of water dynamics in the two hemispheres. The results were interpreted in terms of hemisphere-dependent cellular composition (number of neurons, cell distribution, etc.) as well as specificity of neurological functions (s…

Different a-casein association states and their interaction with lipid vesicles to study antibacterial activity
The interactions between caseins and lipid membranes are fundamental for the physiological function of these proteins. Moreover, the understanding of the underlying molecular mechanisms is of great interest for the development of new casein derived antimicrobial peptides. Indeed, it was already shown that peptides derived from caseins possess antibacterial activity but their mechanisms of action is still debated. Here, we present an experimental study on the interaction between model lipid membranes and a-casein by means of spectroscopy and fluorescence microscopy techniques. a-casein is an unfolded protein that due to its amphiphilic nature is known to self-assembly into non-stable micella…

Analisi di test di Immunofluorescenze indiretta per il supporto alla diagnosi di Malattie Autoimmuni basata su Deep Learning.
2019
La diagnosi delle malattie autoimmuni rappresenta un problema molto importante in medicina. Il test più utilizzato a questo scopo è il test anticorpo antinucleo, un test indiretto di immunofluorescenza. Il metodo proposto affronta tale problema sfruttando le metodologie del Machine Learning. In particolare, fa uso di reti neurali pre-addestrate in grado di classificare i pattern auto anticorpali collegati alle patologie autoimmuni. Gli strati delle reti pre-addestrate e vari parametri di sistema sono stati valutati al fine di ottimizzare il processo. Le prestazioni del sistema sono state valutate in termini di accuratezza in un processo di cross validation, mostrando efficienza e robustezza.

Statistical Regularities in ATM: network properties, trajectory deviations and delays
2012
One of the key enabler to the productivity and efficiency shift foreseen by SESAR will be the business-trajectory concept. The path to a deep understanding of how this new concept impacts on the future SESAR Air Traffic Management scenario goes through a better understanding of the actual air traffic network, and this will be done in the present paper by analyzing traffic data within the framework of complex network analysis. In this paper we will consider flights trajectory data from the Data Demand Repository database. In a first investigation, we perform a network study of the air traffic infrastructure starting from the airports and then refining our analysis at the level of navigation …
