    Splendors and miseries of expired CO2 measurement in the suspicion of pulmonary embolism

    Get PDF
    Capnography has been studied for decades as a potential diagnostic tool for suspected pulmonary embolism. Despite technological refinements and its combination with other non-invasive instruments, no evidence to date allows recommending the use of expired carbon dioxide measurement as a rule-out test for pulmonary embolism without additional radiological testing. Further investigations are, however, still warranted

    A reanalysis of ozone on Mars from assimilation of SPICAM observations

    Get PDF
    We have assimilated for the first time SPICAM retrievals of total ozone into a Martian global circulation model to provide a global reanalysis of the ozone cycle. Disagreement in total ozone between model prediction and assimilation is observed between 45°S–10°S from LS=135–180° and at northern polar (60°N–90°N) latitudes during northern fall (LS=150–195°). Large percentage differences in total ozone at northern fall polar latitudes identified through the assimilation process are linked with excessive northward transport of water vapour west of Tharsis and over Arabia Terra. Modelling biases in water vapour can also explain the underestimation of total ozone between 45°S–10°S from LS=135–180°. Heterogeneous uptake of odd hydrogen radicals are unable to explain the outstanding underestimation of northern polar total ozone in late northern fall. Assimilation of total ozone retrievals results in alterations of the modelled spatial distribution of ozone in the southern polar winter high altitude ozone layer. This illustrates the potential use of assimilation methods in constraining total ozone where SPICAM cannot observe, in a region where total ozone is especially important for potential investigations of the polar dynamics

    Visions de la complexité. Le démon de Laplace dans tous ses états

    Get PDF
    Nous distinguons trois visions de la complexitĂ© afin de clarifier les contours de la recherche dans ce domaine. Nous utilisons le dĂ©mon de Laplace comme rĂ©fĂ©rence pour prĂ©senter ces visions. La vision 1 brise le rĂȘve du dĂ©mon de Laplace en identifiant des systĂšmes particuliers qui lui rĂ©sistent en mathĂ©matiques, physique et informatique. La vision 2 propose une nouvelle version du rĂȘve de Laplace fondĂ©e sur la disponibilitĂ© rĂ©cente de grandes quantitĂ©s de donnĂ©es et de nouvelles technologies de programmation, de stockage et de calcul. La vision 3 met le dĂ©mon face au dĂ©fi de simuler la subjectivitĂ© et ses effets collectifs. (RĂ©sumĂ© d'auteur
