The PCA Lens-Finder: application to CFHTLS

We present the results of a new search for galaxy-scale strong lensing systems in CFHTLS Wide. Our lens-finding technique involves a preselection of potential lens galaxies, applying simple cuts in size and magnitude. We then perform a Principal Component Analysis of the galaxy images, ensuring a clean removal of the light profile. Lensed features are searched for in the residual images using the clustering topometric algorithm DBSCAN. We find 1098 lens candidates that we inspect visually, leading to a cleaned sample of 109 new lens candidates. Using realistic image simulations we estimate the completeness of our sample and show that it is independent of source surface brightness, Einstein ring size (image separation) or lens redshift. We compare the properties of our sample to previous lens searches in CFHTLS. Including the present search, the total number of lenses found in CFHTLS amounts to 678, which corresponds to ~4 lenses per square degree down to i=24.8. This is equivalent to ~ 60.000 lenses in total in a survey as wide as Euclid, but at the CFHTLS resolution and depth.Comment: 21 pages, 12 figures, accepted for publication on A&

Rift Valley Fever in humans and animals in Mayotte, an endemic situation ? [421]

Purpose: Retrospective studies and surveillance on humans and animals revealed that Rift Valley Fever virus (RVFV) has been circulating on Mayotte for at least 10 years. A study was conducted in 2011 to estimate the seroprevalence of RVF in humans and in animals and to identify associated risk factors. Methods: Using a multistage cluster sampling method, 1420 individuals were enrolled in the human study, including 337 children aged 5 to 14 years. For the animal study, 198 seronegative ruminants from 33 randomly selected sentinel ruminant herds were followed up for more than one year. In both studies, information on environment and risk factors was collected through standardized questionnaires. Results: The overall weighted seroprevalence of RVFV antibodies in the general population aged ≥5 years was 3.5% (95% CI 2.6-4.8). The overall seroprevalence of RVFV antibodies in the ruminant population was 25.3% (95% CI 19.8-32.2). Age (≥ 15), gender (men), place of birth on the Comoros, living in Mayotte since less than 5 years, low educational level, farming and living close to a water source were significantly associated with RVFV seropositivity in humans. Major risk factors for RFV infection in animals were continuous access to a water point, previous two-month cumulated rainfall and absence of abortions disposal. High RVF ruminant seroprevalence was observed on the island of Mayotte, with risk factors demonstrated to be similar between human and ruminant, mosquitoes playing an important role in the epidemiological cycle. Conclusion: This circulation could be explained by regular import of the virus from nearby countries through illegal animal movements, presence of susceptible animals and favorable environment for mosquito vectors to maintain virus transmission locally. Relevance: Although resulting in few clinical cases in humans and in animals RVF fever remain a major threat that should be tackled through a “one health approach” in which humans and animals within their ecosystems are included.

Le concept de maladies virales émergentes : quel risque de zoonose pour La Réunion ?

A La Réunion, le risque d'émergence de maladies virales est constitué par plusieurs zoonoses virales qu'il convient de surveiller: infections à virus Sindbis, virus de l'encéphalite japonaise, virus Wesselsbron, virus Nipah, virus Zika, virus West Nile, virus de la fièvre de la vallée du Rift. La lutte contre ces maladies virales émergentes (MVE) passe par une détection précoce des cas et donc un système de surveillance doté d'un véritable réseau d'information, d'alerte et de prévention international.

The Erasmus programme for postgraduate education in orthodontics in Europe: an update of the guidelines

In 1989, the ERASMUS Bureau of the European Cultural Foundation of the Commission of the European Communities funded the development of a new 3-year curriculum for postgraduate education in orthodontics. The new curriculum was created by directors for orthodontic education representing 15 European countries. The curriculum entitled ‘Three years Postgraduate Programme in Orthodontics: the Final Report of the Erasmus Project' was published 1992. In 2012, the ‘Network of Erasmus Based European Orthodontic Programmes' developed and approved an updated version of the guidelines. The core programme consists of eight sections: general biological and medical subjects; basic orthodontic subjects; general orthodontic subjects; orthodontic techniques; interdisciplinary subjects; management of health and safety; practice management, administration, and ethics; extramural educational activities. The programme goals and objectives are described and the competencies to be reached are outlined. These guidelines may serve as a baseline for programme development and quality assessment for postgraduate programme directors, national associations, and governmental bodies and could assist future residents when selecting a postgraduate programm

La revendication du corps chez Lorette Nobécourt. Désir versus Aliénation

Asociada a una corriente basura reducida muy pronto a un eslogan publicitario, Lorette Nobécourt se distingue de algunos contemporáneos cualificados de cínicos por una escritura que parece encarnar la crítica situacionista. La desolladura que sufren sus personajes es, en efecto, el trabajo de deshumanización de lo humano, de mercantilización del cuerpo y de los placeres que emprende la sociedad del espectáculo descrita por Guy Debord. En respuesta, Nobécourt reivindica el cuerpo, en sus aspectos más orgánicos, lejos de las obligaciones morales y hasta una forma de violencia liberadora contra sí mismo y contra los demás, como amparo contra la alienación que acecha.Often associated with a «trash» wave, a movement that is generally reduced to a publicity slogan, Lorette Nobécourt distances herself from the herd of «cynical» contemporary writers through a writing style that embodies situationist criticism. The quartering suffered by her characters is the corollary of the annihilation of their humanity, the merchandization of their bodies and pleasures, undertaken by the society of spectacle. Nobécourt’s answer asserts the body in its most organic component, far from moral obligations, and at times bordering on a form of liberation through violent means (violence turned onto oneself or intended for others)
