Abstract: Purpose: Failure modes and effects analysis (FMEA), is a risk analysis method used at the Radiotherapy Department of Institute Sainte-Catherine as part of a strategy seeking to continuously improve the quality and security of treatments. Patients and methods: The method comprises several steps: definition of main processes; for each of them, description for every step of prescription, treatment preparation, treatment application; identification of the possible risks, their consequences, their origins; research of existing safety elements which may avoid these risks; grading of risks to assign a criticality score resulting in a numerical organisation of the risks. Finally, the impact of proposed corrective actions was then estimated by a new grading round. Results: For each process studied, a detailed map of the risks was obtained, facilitating the identification of priority actions to be undertaken. For example, we obtain five steps in patient treatment planning with an unacceptable level of risk, 62 a level of moderate risk and 31 an acceptable level of risk. Conclusion: The FMEA method, used in the industrial domain and applied here to health care, is an effective tool for the management of risks in patient care. However, the time and training requirements necessary to implement this method should not be underestimated. [Copyright &y& Elsevier]

Abstract: In this paper, we prove the following result: let X be a complex manifold, hyperbolic for the Carathéodory distance and let U be an open set relatively compact in X. Then, there exists such that we get, for the Carathéodory infinitesimal metric, . We also get results concerning fixed points of holomorphic mappings from X to U. [Copyright &y& Elsevier]

Abstract: We are interested in -estimates of harmonic sections of some vector bundles over Riemannian manifolds. Our starting point is the work contained in Chayet and Lohoué (1997) , Dragomirna (1997) , Yau (1971) . The relevant result in what follows is that the principal statement in Chayet and Lohoué (1997) is generic. [Copyright &y& Elsevier]

Abstract: The review of international literature presented here aims at determining the presently available instruments, which measure resilience in adolescents who have been confronted with a traumatism. This research task, focusing on 30 years (1980–2010), was carried out starting from the numerical databases Psyinfo, Psyarticles, Pubmed and Medline, with various key words such as resilience, scale, measure, assessment, protective factors, teenager and adolescent. More than 250 articles have been selected. Among these articles, only five instruments have been identified as enabling to evaluate the characteristics of resilience in teenagers who have been confronted with a traumatism. For all of them, we reported the psychometric development as well as their limitations. This discussion analyses the relevance and the impact of these measuring instruments. [Copyright &y& Elsevier]

Résumé: Objectif: Évaluer la valeur diagnostique de l’algorithme de Berlin, en comparaison aux critères de classification du groupe d’étude européen pour les spondylarthropathies (ESSG) et d’Amor et al. dans une population chinoise ayant une spondylarthropathie indifférenciée (SpAI). Méthode: Quatre-vingt-douze patients présentant une SpAI avec atteinte axiale ont été comparés à 123 patients atteints d’autres maladies rhumatologiques, en utilisant les paramètres de l’algorithme de Berlin, les critères de classification de l’ESSG et ceux d’Amor et al. Résultats: Parmi les 92 patients présentant une spondylarthrite indifférenciée avec atteinte axiale, la prévalence de l’HLA-B27 était de 71,76 % (61/85). Une VS et/ou une CRP élevée était retrouvée chez 40,96 % (34/83) des patients atteints de SpA et une sacro-iliite à l’IRM était retrouvée chez 91 % (39/43) d’entre eux. La spécificité de l’HLA-B27 était de 78 % et était similaire à celle de l’étude de Berlin. La sensibilité/spécificité des critères de l’ESSG, d’Amor et al. et de l’algorithme de Berlin pour le diagnostic des SpAI étaient respectivement de 72,83 %/92,68 %, 64,13 %/93,50 % et de 67,39 %/95,93 %. La coïncidence entre les trois classifications de critères diagnostiques et l’opinion du rhumatologue était modérée. Conclusion: Notre étude a montré que le nouvel algorithme de Berlin a une valeur diagnostique importante dans les spondylarthropathies en Chine, avec une capacité de diagnostic similaire aux critères traditionnels de l’ESSG et d’Amor et al.

Abstract: The radiative transfer problem of heat between two diffuse surfaces placed arbitrarily in a transparent medium is reduced to the calculation of the surface value of mutual radiation. In the case of two very neighbour''s arbitrary surfaces, the numerical calculation of the value of the surface of mutual radiation leads to divergent results. In this article, we present, on one hand, a technique based on the method of contour which avoids the problem of singularity while reducing the number of numerical arithmetic operations and, on the other hand, a comparative analysis of this method with other traditional methods.

Abstract: In this note we describe the stack of smooth hyperelliptic curves of genus g over an algebraically closed field of characteristic two, as a quotient stack of a smooth variety of dimension by a non-reductive algebraic group of dimension , extending a well known result of Vistoli. As an application, we show the Mumford–Vistoli description of the Picard group of the stack is valid in characteristic two. We also describe the natural stratification of by means of higher ramification data with special attention to the supersingular locus. We point out that after stable compactification the stack is not smooth in codimension two. [Copyright &y& Elsevier]

Abstract: The validity of the point-dipole approach, frequently used to estimate the dielectrophoretic force applied upon biological cells in microsystems, is examined. Forces given by this approach are compared to those obtained by the Maxwell stress tensor method. In a needle-plate electrode configuration, results provided by finite element method show that the point-dipole approach is unsatisfactory when cells size is comparable to the gap distance. When subjected to a uniform electric field, cell-to-cell interaction is studied. In that case, the point-dipole approach is very accurate provided that cell-to-cell distance is larger than their radius R. [Copyright &y& Elsevier]

In this article we give two new infinite sequences of perfect non-extremal Riemann surfaces of genus bigger than six. The first sequence consists of weakly eutactic perfect surfaces; the second one of semi-eutactic perfect surfaces. [Copyright &y& Elsevier]

Abstract: We present a realistic anthropomorphic numerical model of the beating heart. It includes the main cardiac anatomical structures, vessels junctions and part of the coronary network. Its main feature is that it is based on an imaging study of the same human subject from which both structural and motion information are retrieved. This confers to the model a remarkable consistency. Heart''s deformation is assessed through successive non linear registrations in cine MR sequences. The resulting model can be used as a reference for the evaluation of cardiac image processing algorithms such as heart segmentation and cardiac image registration. [Copyright &y& Elsevier]
