Additive functionals and push forward measures under Veretennikov's flow
2014
16 pages; In this work, we will be interested in the push forward measure $(\vf_t)_*\gamma$, where $\vf_t$ is defined by the stochastic differential equation \begin{equation*} d\vf_t(x)=dW_t + \ba(\vf_t(x))dt, \quad \vf_0(x)=x\in\mbR^m, \end{equation*} and $\gamma$ is the standard Gaussian measure. We will prove the existence of density under the hypothesis that the divergence $\div(\ba)$ is not a function, but a signed measure belonging to a Kato class; the density will be expressed with help of the additive functional associated to $\div(\ba)$.
Etude de NLRP3 dans les cellules myéloïdes immunosuppressives et les lymphocytes TCD4 dans un contexte de cancer
2013
The inflammasome NLRP3 (NOD like receptor pyd containing 3) is a multiprotein complex notably responsible for IL-1β (interleukine-1β) production, an inflammatory cytokine. Negative effects have been observed in various diseases including cancer. My thesis focuses on the effects of NLRP3 in cancer.In my first project, I studied the NLRP3 inflammasome activation in MDSC (myeloïd derived suppressor cells) after a chemotherapy treatment. Two chemotherapies, 5-Fluorouracil and Gemcitabine, are selectively able to kill MDSC, an immunosuppressive population growing during cancer evolution. MDSC’s death restores anti-tumor immunity for a while but another immunosuppressive population is established…
Résumé des recherches sur les bioagresseurs du riz pluvial
2009
La recherche a été menée sur plusieurs fronts ces dernières campagnes pour la lutte durable contre les bioagresseurs du riz pluvial. Elle s'est orientée vers l'exploitation de la biodiversité des plantes et la recherche de systèmes de culture pour gérer les " vers blancs " ou " scarabées noirs " (Coleoptera, Scarabaeidae), les foreurs de tiges, la pyriculariose et le striga. Les résultats des essais réalisés avec le projet BVlac sur l'utilisation du champignon entomopathogène Metarhizium anisopliae ainsi que les résultats des essais menés avec l'ONG Tafa sur la lutte contre le striga dans différents systèmes de culture seront présentés par ailleurs. Nous rapporterons ici les recherchés mené…
Interactions in the network of Usher syndrome type 1 proteins
2004
International audience; Defects in myosin VIIa, harmonin (a PDZ domain protein), cadherin 23, protocadherin 15 and sans (a putative scaffolding protein), underlie five forms of Usher syndrome type I (USH1). Mouse mutants for all these proteins exhibit disorganization of their hair bundle, which is the mechanotransduction receptive structure of the inner ear sensory cells, the cochlear and vestibular hair cells. We have previously demonstrated that harmonin interacts with cadherin 23 and myosin VIIa. Here we address the extent of interactions between the five known USH1 proteins. We establish the previously suggested sans-harmonin interaction and find that sans also binds to myosin VIIa. We …
La démographie chinoise en mutation
2009
International audience; Avec une population estimée par l'ONU à 1335 millions d'habitants en juillet 2009, soit 19,6 % de la population mondiale, la Chine est le pays le plus peuplé du monde devant l'Inde (1175 millions) et les États-Unis (309 millions). Sa population est 10 fois celle du Japon, 20 fois celle de la France. Le président Jiang Zemin avait déclaré en octobre 1999, lors du cinquantenaire de la Révolution Communiste que " le problème nº 1 de la Chine est le contrôle de la croissance de population ". Si la masse de population a pu apparaître comme un atout à l'époque maoïste, elle est perçue aujourd'hui tant comme une contrainte (logement, alimentation, emploi) que comme un argum…
Modernités dans les Amériques : des avant-gardes à aujourd’hui
2018
Reposer aujourd’hui la question de la modernité – littéraire, artistique, sociale ou politique – revient à employer le mot au pluriel. Ce choix implique que l’on ne se réduise pas au terme plurivoque, et souvent ambigu, de modernisme. Ce dernier, souvent convoqué pour désigner l’imaginaire culturel de la modernité, peine à rendre compte des écarts qui se manifestent dans la manière de penser le rapport au temps, à l’histoire et à la culture. « La modernité n’est pas un mouvement, comme dada o...
‘Strange old Italian dresses’: Walter Pater, Victorian fashionista?
2019
This article discusses Aesthetic dress as conceived by Walter Pater. Indeed in “Leonardo Da Vinci” (1869), the unfinished Gaston de Latour (1888-1894?), “The School of Giorgione” (1877) and “A Prince of Court Painters” (1885), Pater mentions and describes dress with special emphasis on details. Such descriptions belong to a series of writings on Aesthetic dress, admittedly a core component of British Aestheticism. Pater’s descriptions should therefore be contrasted to the 1870s portraits of Whistler, and to the 1880s-1890s writings of Whistler, Oscar Wilde and Max Beerbohm, along with the caricatures of Aesthetes by George du Maurier and Sir Leslie Ward. Pater responds by progressively deli…
Hugh MacDiarmid’s Poetics of Commitment: the Modern Stigmata of Bereavement
2016
In the 1930s, the lingering absence of God and of a stable reality engulfed the work of the poet Hugh MacDiarmid, leader of the Scottish Renaissance Movement. To counter this void, like many others at the time, MacDiarmid found refuge in communism and nationalism and started to write political and idealist poetry. In his poems, his political idealism comes into being in the association of reality and ideal, symbolised first by Jean and Sophia, the characters of A Drunk Man Looks at the Thistle (1926), and duplicated later in the fantasised image of Lenin, perfect blending of idea and action. Rejecting Sartre’s denial of the political effect poetry can have, the violence of MacDiarmid’s work…
The Politics of Utopia: Walter Pater’s “Lacedaemon”
2016
Walter Pater is not usually considered as a politically committed writer, neither is Aestheticism of which he was the gifted theoretician with The Renaissance (1873). Although the political commitments of the Aesthetic movement have been questioned over the last two decades, both by including women aesthetes, and by re-evaluating the movement’s dissemination among the middle classes, discussion of Pater’s political ideas is almost non-existent. His Plato and Platonism (1893) is however not so remote from politics since it discusses Plato’s political philosophy. In particular, “Lacedaemon”, the chapter devoted to Sparta, enables Pater to intervene in the political debate from an original sta…
Parental and professional agency in terminations for fetal anomalies: analysis of Finnish women's accounts
2013
This study explores the construction of parental and professional agency in the written accounts by women who have undergone selective abortion (N=8). The analysis of the data was based on qualitative, linguistic discourse analysis. The accounts indicate that the mothers themselves exhibited both strong and weak agency during the process of prenatal diagnosis. The role of the professionals was usually discussed in these accounts concerning only the phases of pregnancy when something out of ordinary had been detected. After the termination, the mothers expressed that they were forced to exhibit strong agency and find ways to cope with their distress unaided due to a lack of professional supp…
