2 Cas Originaux de Fistule Œsophagienne

Les fistules œsophagiennes sont des affections rares chez les Carnivores Domestiques. Elles se définissent comme une communication entre l'œsophage et la peau ou une cavité. Deux cas illustrent la diversité de ces fistules : fistule œsophago-trachéale et œsophago-cutanée

Molecular spintronics: Coherent spin transfer in coupled quantum dots

Time-resolved Faraday rotation has recently demonstrated coherent transfer of electron spin between quantum dots coupled by conjugated molecules. Using a transfer Hamiltonian ansatz for the coupled quantum dots, we calculate the Faraday rotation signal as a function of the probe frequency in a pump-probe setup using neutral quantum dots. Additionally, we study the signal of one spin-polarized excess electron in the coupled dots. We show that, in both cases, the Faraday rotation angle is determined by the spin transfer probabilities and the Heisenberg spin exchange energy. By comparison of our results with experimental data, we find that the transfer matrix element for electrons in the conduction band is of order 0.08 eV and the spin transfer probabilities are of order 10%.Comment: 13 pages, 6 figures; minor change

Histoire et critique textuelle des documents arabes et syriaques

Programme de l’année 2008-2009 : I. Commentaires sur Aristote (syriaque). — II. Logique et théorie de la science (arabe)

El-Rouayheb, Khaled, Relational Syllogism and the History of Arabic Logic, 900-1900 (Brill, 2010)

Dans l’historiographie traditionnelle, l’idée est très généralement reçue que les travaux de logique, ou d’ailleurs plus largement de philosophie, rédigés en langue arabe après le xiiie siècle n’offrent rien de neuf par rapport à ce qui a été produit auparavant et que la culture arabe en ces matières est sur le déclin. S’agissant de la logique, cette opinion est représentée par l’ouvrage de Nicholas Rescher, The Development of Arabic Logic, Pittsburgh, 1964, à vrai dire le seul ouvrage qui se..

A virtual imaging platform for multi-modality medical image simulation.

International audienceThis paper presents the Virtual Imaging Platform (VIP), a platform accessible at http://vip.creatis.insa-lyon.fr to facilitate the sharing of object models and medical image simulators, and to provide access to distributed computing and storage resources. A complete overview is presented, describing the ontologies designed to share models in a common repository, the workflow template used to integrate simulators, and the tools and strategies used to exploit computing and storage resources. Simulation results obtained in four image modalities and with different models show that VIP is versatile and robust enough to support large simulations. The platform currently has 200 registered users who consumed 33 years of CPU time in 2011

Reconstruction en Tomographie d'emission mono-photonique avec correction d'atténuation par l'algorithme du Résidu Minimal

Cet article décrit une méthode itérative de reconstruction d'image avec correction d'atténuation à partir de mesures de projections atténuées en Tomographie d'Émission Mono-Photonique. Cette méthode est basée sur l'application de l'algorithme du Résidu Minimal à la résolution d'un système linéaire quasi-symétrique. Comme le problème inverse est mal posé, des techniques de régularisation sont employées pour stabiliser la reconstruction. Nous présentons une méthode de régularisation spatialement adaptative. L'algorithme de reconstruction est mis en oeuvre à la fois pour la géométrie parallèle et la géométrie conique. Les résultats expérimentaux obtenus sur des données simulées, sur des fantômes anatomiques et sur des données cliniques montrent que l'algorithme proposé est au moins deux fois plus rapide que l'algorithme standard du gradient conjugué préconditionné, et que la méthode de régularisation adaptative est bien adaptée

An International Comparison of Female and Male Students' Attitudes to the Use of Animals

P. 7-26Previous research has demonstrated that in households where the male partner is more dominant, there is convergence in male and female attitudes towards animals, whereas if the female partner is empowered they exhibit greater empathy towards animals than the male partner. We tested this theory of ‘female empowered empathy’ internationally in a survey of female and male students’ attitudes towards use of animals, conducted in 11 Eurasian countries: China, Czech Republic, Great Britain, Iran, Ireland, South Korea, Macedonia, Norway, Serbia, Spain and Sweden. Gender empowerment was estimated for each country using the Gender Empowerment Measure designed by the United Nations. The survey was administered via the internet in universities within countries, and 1,902 female and 1,530 male student responses from 102 universities were received. Respondents rated the acceptability of 43 major concerns about human use of animals, and the importance of 13 world social issues, including animal protection, environmental protection and sustainable development. Females had greater concern for animal welfare and rights than males. There was a positive correlation between the Gender Empowerment Measure and the ratio of female to male concern for animal welfare and rights, but not for other world issues. Thus in countries where females were more empowered, principally Sweden, Norway and Great Britain, females had much greater concern than males for animal issues, whereas in other countries the responses of males and females were more similar. Across countries female students were more likely to avoid meat and less likely to avoid eggs, milk and seafood than male students, and were more likely to have kept pets than males. Females rated cats as more sentient than males did. The results demonstrate that females have greater concern for animal welfare and rights than males, and that this is more likely to be expressed in countries where females are relatively empowered, suggesting that ‘emancipated female empathy’ operates across countries as well as at a local level.S

Epidemiology, clinical management, and outcomes of dogs involved in road traffic accidents in the United Kingdom (2009–2014)

Electronic patient records of dogs attending practices participating in the VetCompass Programme were assessed against selection criteria used to define RTA cases. Cases identified as RTAs were identified and manually verified to calculate prevalence. Univariable and multivariable logistic regression methods were used to evaluate associations between risk factors and RTA. The prevalence of RTA was 0.41%. Of the RTA cases, 615 (74.9%) were purebred, 322 (39.2%) were female, and 285 (54.8%) were insured. The median age at RTA was 2.5 years. After accounting for the effects of other factors, younger dogs had increased odds of an RTA event: dogs aged under 3 years showed 2.9 times the odds and dogs aged between 6–9 years showed 1.8 times the odds of an RTA event compared with dogs aged over 14 years. Males had 1.4 times the odds of an RTA event compared with females. Overall, 22.9% of cases died from a cause associated with RTA. Of dogs with information available, 34.0% underwent diagnostic imaging, 29.4% received intravenous fluid‐therapy, 71.1% received pain relief, 46.0% were hospitalized, and 15.6% had surgery performed under general anesthetic
