Local Structure of Supported Keggin and Wells-Dawson Heteropolyacids and Its Influence on the Catalytic Activity
2019
[EN] Keggin [PW12O40]3– and Wells–Dawson [P2W18O62]6– heteropolyanions are nanosized transition-metal-oxygen clusters belonging to the heteropolyacids (HPAs) family. They are widely used as catalysts due to their high Brønsted acidity, and their dispersion on solid supports favors the accessibility to their acid sites generally increasing the catalytic activity. A series of binary materials composed of Keggin or Wells–Dawson HPAs and SiO2, TiO2, and ZrO2 have been prepared by impregnation or solvothermal methods. Remarkable differences have been found in the catalytic activities among the unsupported and supported HPAs. These differences have been correlated in the past to the structural ch…
Three-dimensional splitting dynamics of giant vortices in Bose-Einstein condensates
2018
We study the splitting dynamics of giant vortices in dilute Bose-Einstein condensates by numerically integrating the three-dimensional Gross-Pitaevskii equation in time. By taking advantage of tetrahedral tiling in the spatial discretization, we decrease the error and increase the reliability of the numerical method. An extensive survey of vortex splitting symmetries is presented for different aspect ratios of the harmonic trapping potential. The symmetries of the splitting patterns observed in the simulated dynamics are found to be in good agreement with predictions obtained by solving the dominant dynamical instabilities from the corresponding Bogoliubov equations. Furthermore, we observe…
The suffragette movement in H.G. Wells's "Ann Veronica" and May Sinclair's "The Tree of Heaven"
2016
In H.G. Wells’s Ann Yeronica (1909), the eponymous heroine embraces new womanhood and a rangę of feminisms in her search for life. Ann Veronica attends suffrage and other radical meetings in London once she has left her father and home in order to “live”. She is arrested during a raid on the House of Commons, while trying to defend an elderly suffragette. However, the harshness of prison life forces Ann Veronica to see the error of her ways and to seek a reconciliation with her father upon her release. Here, militant suffragism is portrayed as a turning point. It is a reaction that brings down all the powers of patriarchy upon her and causes her to accept “life” as it is rather than seek to…
Towards a Real-time Mitigation of High Temperature while Drilling using a Multi-agent System
2018
International audience; In oilfield wells, while drilling for several kilometers below surface, high temperature damages the drilling tools. This costs money and time for tripping operations to change the damaged tool. Existing temperature mitigation techniques have several drawbacks including a long response time, analogue signal issues and human intervention. In this work, we empower the down-hole tools with a coordination mechanism to mitigate high temperature in soft real time by controlling a down-hole actuator through a voting process. The tools are represented by agents that control the sensors and actuators embedded in these tools. To implement the proposed system properly, a model …

Novel missense mutation of the TP63 gene in a newborn with Hay-Wells/Ankyloblepharon-Ectodermal defects-Cleft lip/palate (AEC) syndrome: clinical rep…
2021
Abstract Introduction Ankyloblepharon-ectodermal defects-cleft lip/palate (AEC) syndrome, also known as Hay-Wells syndrome, is a rare genetic syndrome with ectodermal dysplasia. About 100 patients have been reported to date. It is associated to a heterozygous mutation of the tumor protein p63 (TP63) gene, located on chromosome 3q28. Typical clinical manifestations include: filiform ankyloblepharon adnatum (congenital adherence of the eyelids), ectodermal abnormalities (sparse and frizzy hair, skin defects, nail alterations, dental changes and hypohidrosis), and cleft lip/palate. Diagnostic suspicion is based on clinical signs and confirmed by genetic testing. Patient’s presentation We hereb…
Nasium : les fouilles du "Cul de Breuil" à Saint-Amand-sur-Ornain (Meuse) : Fouille triennale 2012-2014. Rapport intermédiaire 2012
2011
This report presents the results of a second series of excavations carried out between the oppidum of Boviolles and the ancient city of Nasium. It affects an occupation dated between La Tène D2 and the beginning of the augustean period, characterized by a causeway linking the two entities, a level delivering traces of artisanal activities, wells and a cooking kiln. This occupation is also characterized by the presence of the Roman army embodied in many militaria. This presence is central to the issue of the development of the ancient settlement of Nasium.
Woman as a mate and comrade of man in H. G. Wells’s "The New Machiavelli"
2019
H. G. Wells’s The New Machiavelli (1911) was the bold statement of the rights of women in the new century. It was, of course, useless to deny that The New Machiavelli had a sexual base. The sexual relations between men and women had come to dominate Wells’s mind, and it was going to be an important topic in his books. Wells’s novel, which is a cry of anger against the oppressive conventions of society, is in part based on autobiographical details of Wells’s own life, his affair in 1908 with Amber Reeves, a brilliant Cambridge graduate. Central to Wells’s doctrines of male-female relationships is his understanding of the duality of love. Wells stresses the importance of two people loving eac…
