Looking for Echo in George Du Maurier’s Trilby: An Intermedial Perspective

L’article porte sur la figure d’Écho dans Trilby de George Du Maurier (1894). Le récit, bien que centré sur la voix de l’héroïne, et saturé de références mythologiques, ne fait pas apparaître le nom de la nymphe. Nous expliquerons ainsi ce paradoxe : l’hypothèse est qu’il s’agit d’une « allusion latente » qui met le lecteur en alerte face aux motifs de la répétition et du dédoublement du corps de la chanteuse. Les analyses portent aussi bien sur le texte du roman que sur certaines des illustrations de l’auteur. Un recueil d’essais de Roland Barthes publié en anglais sous le titre Image Music Text (1977), en particulier “The Grain of the Voice”, fournit le cadre de référence théorique de l’article. La mise en perspective du texte et des images du roman avec diverses œuvres picturales (peintures d’Edgar Degas et de Thomas Eakins, photographie de Julia Margaret Cameron, dessin de J.J. Grandville) permet de saisir la portée mythique, sociale et culturelle du corps et de la voix de l’artiste, ainsi que de la musique comme art supérieur, faisant d’Écho une figure symbolique de la place ambivalente de la femme dans la littérature et la société victorienne.This article deals with the figure of Echo in George Du Maurier’s Trilby (1894). The narrative is centred on the heroine’s voice, and contains numerous mythological references, and yet there is no mention of the nymph. I posit that Du Maurier is using a “latent allusion”, which attracts the reader’s attention through motifs like repetition, and the doubling/dismembering of the singer’s body. My analysis focuses both on the novel itself and its authorial illustrations. I will take my theoretical framework from a collection of essays by Roland Barthes, published in English as Image Music Text (1977), and especially from “The Grain of the Voice”. I will also compare the texts and images from the novel with a selection of pictorial works (paintings by Edgar Degas and Thomas Eakins, a photograph by Julia Margaret Cameron, and a drawing by J.J. Grandville), in order to capture the mythical, social and cultural significance of the artist’s voice and body, as well as the notion of music as a superior art form, in which Echo emerges as a symbolic figure, representative of the ambivalent position of women in Victorian literature and society

Proteomic and functional analyses of the virion transmembrane proteome of cyprinid herpesvirus 3

Virion transmembrane proteins (VTPs) mediate key functions in the herpesvirus infectious cycle. Cyprinid herpesvirus 3 (CyHV-3) is the archetype of fish alloherpesviruses. The present study was devoted to CyHV-3 VTPs. Using mass spectrometry approaches, we identified 16 VTPs of the CyHV-3 FL strain. Mutagenesis experiments demonstrated that eight of these proteins are essential for viral growth in vitro (ORF32, ORF59, ORF81, ORF83, ORF99, ORF106, ORF115, and ORF131), and eight are non-essential (ORF25, ORF64, ORF65, ORF108, ORF132, ORF136, ORF148, and ORF149). Among the non-essential proteins, deletion of ORF25, ORF132, ORF136, ORF148, or ORF149 affects viral replication in vitro, and deletion of ORF25, ORF64, ORF108, ORF132, or ORF149 impacts plaque size. Lack of ORF148 or ORF25 causes attenuation in vivo to a minor or major extent, respectively. The safety and efficacy of a virus lacking ORF25 were compared to those of a previously described vaccine candidate deleted for ORF56 and ORF57 (Δ56-57). Using quantitative PCR, we demonstrated that the ORF25 deleted virus infects fish through skin infection and then spreads to internal organs as reported previously for the wild-type parental virus and the Δ56-57 virus. However, compared to the parental wild-type virus, the replication of the ORF25 deleted virus was reduced in intensity and duration to levels similar to those observed for the Δ56-57 virus. Vaccination of fish with a virus lacking ORF25 was safe but had low efficacy at the doses tested. This characterization of the virion transmembrane proteome of CyHV-3 provides a firm basis for further research on alloherpesvirus VTPs. IMPORTANCE Virion transmembrane proteins play key roles in the biology of herpesviruses. Cyprinid herpesvirus 3 (CyHV-3) is the archetype of fish alloherpesviruses and the causative agent of major economic losses in common and koi carp worldwide. In this study of the virion transmembrane proteome of CyHV-3, the major findings were: (i) the FL strain encodes 16 virion transmembrane proteins; (ii) eight of these proteins are essential for viral growth in vitro; (iii) seven of the non-essential proteins affect viral growth in vitro, and two affect virulence in vivo; and (iv) a mutant lacking ORF25 is highly attenuated but induces moderate immune protection. This study represents a major breakthrough in understanding the biology of CyHV-3 and will contribute to the development of prophylactic methods. It also provides a firm basis for the further research on alloherpesvirus virion transmembrane proteins

Three-dimensional right-ventricular regional deformation and survival in pulmonary hypertension

International audienceBackground: Survival in pulmonary hypertension (PH) relates to right ventricular (RV) function. However, the RV unique anatomy and structure limit 2D analysis and its regional 3D function has not been studied yet. The aim of this study was to assess the implications of global and regional 3D RV deformation on clinical condition and survival in adults with PH and healthy controls.Methods and Results: We collected a prospective longitudinal cohort of 104 consecutive PH patients and 34 healthy controls between September 2014 and December 2015. Acquired 3D transthoracic RV echocardiographic sequences were analysed by semi- automatic software (TomTec 4D RV-Function 2.0). Output meshes were post-processed to extract regional motion and deformation. Global and regional statistics provided deformation patterns for each subgroup of subjects.RV lateral and inferior regions showed the highest deformation. In PH patients, RV global and regional motion and deformation (both circumferential, longitudinal and area strain) were affected in all segments (p-18% was the most powerful RV function parameter, identifying patients with a 48%-increased risk of death (AUC 0.83 [0.74-0.90], p<0.001).Conclusions: RV strain patterns gradually worsen in PH patients and provide independent prognostic information in this population

The ATLAS3D project - XXVII : Cold gas and the colours and ages of early-type galaxies

Date of Acceptance: 16/12/2013We present a study of the cold gas contents of the ATLAS3D early-type galaxies, in the context of their optical colours, near-ultraviolet colours and Hβ absorption line strengths. Early-type (elliptical and lenticular) galaxies are not as gas poor as previously thought, and at least 40 per cent of local early-type galaxies are now known to contain molecular and/or atomic gas. This cold gas offers the opportunity to study recent galaxy evolution through the processes of cold gas acquisition, consumption (star formation) and removal. Molecular and atomic gas detection rates range from 10 to 34 per cent in red sequence early-type galaxies, depending on how the red sequence is defined, and from 50 to 70 per cent in blue early-type galaxies. Notably, massive red sequence early-type galaxies (stellar masses >5 × 1010 M⊙, derived from dynamical models) are found to have H I masses up to M(H I)/M* ∼ 0.06 and H2 masses up to M(H2)/M* ∼ 0.01. Some 20 per cent of all massive early-type galaxies may have retained atomic and/or molecular gas through their transition to the red sequence. However, kinematic and metallicity signatures of external gas accretion (either from satellite galaxies or the intergalactic medium) are also common, particularly at stellar masses ≤5 × 1010 M⊙, where such signatures are found in ∼50 per cent of H2-rich early-type galaxies. Our data are thus consistent with a scenario in which fast rotator early-type galaxies are quenched former spiral galaxies which have undergone some bulge growth processes, and in addition, some of them also experience cold gas accretion which can initiate a period of modest star formation activity. We discuss implications for the interpretation of colour–magnitude diagramsPeer reviewedFinal Accepted Versio

The Atlas3D project -- XIII. Mass and morphology of HI in early-type galaxies as a function of environment

We present the Atlas3D HI survey of 166 nearby early-type galaxies (ETGs) down to M(HI)~10^7 M_sun. We detect HI in ~40% of all ETGs outside the Virgo cluster and in ~10% of all ETGs inside it. This demonstrates that it is common for non-cluster ETGs to host HI. The HI morphology varies from regular discs/rings (the majority of the detections) to unsettled gas distributions. The former are either small discs (M(HI)<10^8 M_sun) confined within the stellar body and sharing the same kinematics of the stars, or large discs/rings (M(HI) up to 5x10^9 M_sun) extending to tens of kpc from the host galaxy and frequently kinematically decoupled from the stars. Neutral hydrogen provides material for star formation in ETGs. Galaxies with central HI exhibit signatures of star formation in ~70% of the cases, ~5 times more frequently than galaxies without central HI. The central ISM is dominated by molecular gas. In ETGs with a small gas disc the conversion of HI into H_2 is as efficient as in spirals. The ETG HI mass function has M*~2x10^9 M_sun and slope=-0.7. ETGs host much less HI than spirals as a family. However, a significant fraction of them is as HI-rich as spirals. The main difference between ETGs and spirals is that the former lack the high-column-density HI typical of the bright stellar disc of the latter. We find an envelope of decreasing M(HI) with increasing environment density. The gas-richest ETGs live in the poorest environments (where star-formation is more common), galaxies in the centre of Virgo have the lowest HI content, and the cluster outskirts are a transition region. We find an HI morphology-density relation. At low environment density HI is mostly distributed on large discs/rings. More disturbed HI morphologies dominate environment densities typical of rich groups, confirming the importance of processes occurring on a galaxy-group scale for the evolution of ETGs.Comment: Accepted for publication on MNRA

Cartographie des forêts anciennes de France : objectifs, bilan et perspectives

Il y a dix ans démarraient les premiers travaux de vectorisation, à l'échelle régionale, des forêts de la carte d'Etat-Major, en vue de l'établissement d'une carte nationale des forêts à longue continuité de l'état boisé. Où en est-on aujourd'hui ? Nous faisons le point de l'avancement des travaux et en tirons les premiers enseignements, en répondant aux questions suivantes : Quels sont les définitions et concepts sous-jacents à ces travaux ? Pourquoi cartographier les forêts dites "anciennes" ou "récentes" ? L'analyse des institutions ayant réalisé le travail montre que ce sont principalement les milieux de la conservation qui ont été moteurs dans ces travaux. Mais la production et la qualité des produits bois sont aussi concernés par cette cartographie. Le rôle actuel de puits de carbone des forêts françaises ne peut par exemple se comprendre qu'au travers de cette dynamique forestière ancienne. Pourquoi une focalisation sur la première moitié du XIXe siècle comme date de référence ? Que signifie la notion de minimum forestier ? Quelles en sont les limites ? Quels sont les supports de données les plus intéressantes pour cette cartographie ? Pourquoi la carte d'Etat-Major est une source particulière d'information, dans l'objectif de la cartographie des forêts anciennes, parmi la multitude de cartes ou statistiques disponibles à différentes dates et échelles ? Quelles sont les méthodes d'acquisition de la donnée ? Quelle est la précision spatiale des cartes d'occupation du sol obtenues ? Les principaux problèmes posés par l'utilisation de la carte d'Etat-Major seront présentés, ainsi que la façon dont différents projets y ont répondu. Quels résultats ont été obtenus ? Nous reviendrons entre autres sur l'estimation de la surface forestière française à la date de son minimum. Les cartes déjà réalisées, sur 33% du territoire, permettent de dessiner avec précision et de comparer les changements d'occupation du sol dans différentes régions de France, en termes de pourcentage de déboisement, reboisement et taux de forêt ancienne dans la forêt actuelle. Les évolutions du couvert forestier issues d'autres sources non cartographiques sont-elles confirmées ? Le lien avec le type de propriété foncière est particulièrement intéressant à analyser. Dans plusieurs zones de France (Pyrénées, Luberon, Alpes, Lorraine, Nord-Pas-de-Calais...) ont été réalisés des croisements entre ces cartes et les bases de données régionales de relevés floristiques (Inventaire forestier national, conservatoires botaniques). Ce nouveau type d'analyse permet d'identifier rapidement les espèces végétales liées à la continuité de l'état boisé, dites espèces de forêts anciennes, et les traits de vie qui leur sont associés. Nous présenterons une synthèse de ces résultats. Dans la moitié des zones déjà cartographiées, ce sont toutes les occupations du sol anciennes qui ont été numérisées et non seulement les forêts. Nous évoquerons l'intérêt de ce cadastre ancien, au-delà des seules questions forestières, pour le suivi de la dynamique à long terme des prairies, des milieux humides, des vignes ou des milieux urbanisés. Les techniques de vectorisation des occupations anciennes du sol évoluent vers une simplification et une accélération qui laisse présager une fin du travail plus rapide que prévue initialement, parfois au détriment de la qualité. L'extension à la France entière permettra une vision à la fois à petite échelle mais localement précise des mouvements des masses forestières. Nous discuterons les perspectives de recherche et les développements en cours, ouverts par ces progrès
