Повний текст джерелаThe El Niño Southern Oscillation (ENSO) is the most intense climatic fluctuation on Earth after the seasonal cycle. The observation, understanding and forecast of this fluctuation with worldwide impacts are major scientific issues. This thesis (entitled "Simple Models for Understanding the Mechanisms and Modulation of ENSO") documents various aspects of ENSO such as its mechanisms, its modulation and its forecast. Those various aspects are tackled by developing a hierarchy of models of the equatorial Pacific, of increasing complexity, ranging from conceptual models to a data assimilation method in an intermediate complexity model. We study at first mechanisms of ENSO formation. We develop an alternative derivation of the recharge/discharge conceptual model where ENSO arises from a basin-wide adjustment of the equatorial thermocline. We also implement an original diagnostic in a model of equatorial coupled instabilities, which evidences a new mechanism of ENSO formation where reflections at the ocean boundaries are secondary. The background ocean stratification contributes to the decadal modulation of ENSO characteristics. This relation is adressed in a new reduced model that takes into account the gravest baroclinic modes of a continusouly stratified ocean. The space of model solutions is explored, indicating a control on ENSO stability by characteristics of the equatorial thermocline. The sensitivity to stratification over the recent decades is put in perspective with the sensitivity to thermodynamic and atmospheric feedbacks. We stress in particular certain limitations of usual methods of estimation of the thermocline feedback in the central Pacific. Finally, we implement an Ensemble Kalman Filter method in an already existing intermediate model of the equatorial Pacific, in order to assimilate sea level observations and to initialize retrospective forecasts. We show that the major model constraint is on the basin modes that are associated to the recharge/discharge process of the equatorial Pacific. Our work provides a formalism to diagnose the modulation of ENSO characteristics in observations, climate projections and forecasts. Results support the need to extent the understanding of ENSO mechanisms, in order to account for the diversity of observed regimes and to improve forecasts

Повний текст джерелаGlobal changes induce high pressure on marine ecosystems, biodiversity and fisheries. In thatregard many scientists advocate the use of an ecosystem-based fisheries management (EBFM).However, the operationalization of such an ecosystem-based approach remains challenging. Thisthesis gives insight into the operationalization of EBFM for tropical coastal fisheries. To achievethat we propose a multi-species, multi-fleet and multi-criteria model of intermediate complexity(MICE), taking into account the impacts of global changes. The model is calibrated for theGuyanese small-scale coastal fishery. At local scale, global warming, the increase of populationand the variations of mangrove surface are considered as the main drivers of global changes.From the calibrated model, several fishing management strategies and environmental scenariosare compared in the long-run. In this context, the first results published (chapter 3) show thedetrimental impact of climate change on both marine biodiversity and fishery production. Thispaper also highlights the major role of ecological competition between species. Then, in thechapter 4, by comparing the bio-economic results obtained under each fishing managementstrategy, this research demonstrates the interest of Ecoviability strategies in terms ofsustainability and ecologico-economic reconciliation. The last results displayed in this thesis, inchapter 5, underline the positive impact of mangrove on ecologico-economic sustainability of thecoastal fishery, even if it is insufficient to balance the negative impact of warming. Beyond theseresults, this thesis brings a series of important transverse contributions. First, methodologically,this research permits to show the benefits of MICE to operationalize EBFM. Then, by highlightingthe major ecological factors of the ecosystem with on the one hand the interaction ofcompetition and on the other hand the environmental filters, the work sheds light on theecological complexities necessary for the EBFM. Finally, by evaluating and comparing theecologico-economic performances of several fishing strategies, this research permits to outlinepolicy recommendations to move towards the sustainability of the Guyanese coastal fishery andtowards EBFM, in the face of global changes

Повний текст джерелаIntermediate-mass stars (2 M⊙ ≤ M ≤ 10 M⊙) are among the dominant sources of FUV interstellar field in the Galaxy. They regulate the phases of interstellar medium and the whole process of galactic star formation. While solar-type and massive protostars have been and continue to be the subject of many studies, the formation of intermediate stars has been relatively little studied. Their physical structure, chemical composition and molecular richness are still a subject to explore.The aim of my thesis is to obtain a detailed census, as complete as possible ,of the physical and chemical structure of an isolated intermediate-mass protostar: Cep E-mm (100 L⊙).I have completed a spectral survey of the molecular emission in the (sub)millimetre bands between 72 and 350 GHz with IRAM 30m telescope. The sensitivity of the observations made it possible to identify the presence of numerous complex organic molecules (COMs) in the protostar envelope, but also several unusual molecular species in the protostellar jet. Additionally, further observations with the IRAM 30m telescope made it possible to map the molecular emission at large scale (20’’ to 11’’; 15000 to 8000 AU). In parallel, interferometric maps of the molecular emission between 86 – 90 GHz and 216 – 220 GHz were obtained with NOEMA, the IRAM interferometer, at 1.4’’ (1000 AU) of angular resolution. These observations allowed me to obtain the distribution of molecular emission within the source, from large scales in the outer parts of the extended envelope, to the small scales in the hot corino region. The single-dish and interferometric observations were reduced and analysed in a meticulous manner. More precisely, I identified and separated the molecular emission contribution from the different physical regions as observed with the IRAM 30m telescope. I have identified and characterized fours physical components that differ in their spectroscopic properties and excitation conditions: the extended envelope, the hot corino, the bipolar outflow and the high-velocity jet. Finally, the anisotropy of the brightness distribution from the outflow system cannot be modelled by the “classical” Gaussian approach. I have developed specific tools to estimate, in a semi-analytical manner, the coupling between the telescope lobe and the source

Повний текст джерелаIn this thesis we are essentially interested in questions concerning algebraic complexity classes of decision problems and of evaluation problems. More precisely, we study on the one hand the model of Blum, Shub and Smale (BSS) for the recognition of languages over arbitrary structures thanks to algebraic circuits, and on the other hand the model of Valiant for the computation of polynomials thanks to arithmetic circuits. Our results show that in order to separate complexity classes, it is easier to work on evaluation problems, that is, in Valiant's model. This confirms our intuition that, the model being simpler (there are no test gates), lower bounds should be easier to obtain. In particular, we show two transfer results. The first concerns the algebraic versions of P and NP: over a field of characteristic zero, the separation of P and NP in BSS model thanks to problems in NP "without multiplication" implies the separation of P and NP in Valiant's model. The second concerns the question "P=PSPACE?": after defining analogues of PSPACE in both algebraic models, we show that separating P and PSPACE, over the reals or over the complex field, is easier in Valiant's model. More succinctly, we also study the manipulation by Turing machines of polynomials given by arithmetic circuits. Indeed, this way of encoding polynomials can be much shorter than the list of monomials. But the study of two examples (computing the coefficient of a monomial and computing the degree of a polynomial) shows that the manipulation of polynomials given by circuits is hard, even if their degree is polynomial and if we work over a field of positive characteristic

Повний текст джерелаMesenchymal neoplasms of intermediate malignancy were introduced by the World Health Or-ganization (WHO) classification of soft-tissue and bone tumors. This terminology accounts for a heterogeneous group of neoplasms, which common denominator is to fail usual prognostic approaches. Solitary fibrous tumor, a rare neoplasia, is an interesting model of such tumors with a potential for local recurrence and a low risk of metastasis. In this context, the main goal of this work was to define the biology of these neoplasms, using a multimodal approach. Considering their diagnosis, our work confirmed the excellent performance of STAT6 immunohistochemistry and its greater sensitivity compared to targeted RT-PCR. Considering the prognosis, we further specified the clinical, histological and molecular parameters that impact survival: surgical margin, mitotic index and necrosis. We revised the criteria of the Marseille Grading Scheme (MGS) accordingly, which resulted in high prognosis value for meningeal forms. Our results point that the whole spectrum is of intermediate malignancy as long as the follow-up is sufficient to allow detection of delayed adverse events. Our works also showed that the type of NAB2-STAT6 tran-script and the mutation of TERT promoter do not carry an independent prognostic value, albeit certain types of transcripts were associated with particular clinical and histological criteria. To conclude, the diagnosis and prognosis assessment of solitary fibrous tumors can be based on accessible histological criteria albeit their prognosis assessment is not fully satisfactory yet

Повний текст джерелаModels of development, capitalism and industrialism are also big dynamics of risk by their ability altering social world. At the level of firms, innovation and competition requires ongoing adjustment. Subject to their owners, companies focus on financial risk. Other risks are subordinate to the primary target. The dynamics of risk are changing the firm at the rate of external demands. The competition justifies harmful cost reductions and destabilizing re-engineering. The aim of safety is to reduce the uprising conditions of risk. Safety is a complex social building. Locally, safety seems a melt of man and tools within an organization. Overall, control of the safety is a challenge between risk and cost in the unit. Between cost and efficiency, management makes its own choice. As the shipowner and his vessel, the factory management has the keys to safety. It arbitrates between budgets and plays competition between territories. Ensuring impunity, equivalence and non-discrimination, international law guarantees competition between all States and flags. With globalization, we entered the era of the safety market. Safety is one of the production factors in global competition. Business leaders incorporate it into their overall strategies. With this factor in mind they choose their factories geographical location but also the allocation of budgets inside the firm. In selecting safety participants, the Executive create a unique picture of what safety is that corresponds to their paradigms. The rebuilding of safety in production units is played locally but also globally and by discovering the complexities of the dynamics of risk and the way of building safety
