Quantification of uncertainties from ensembles of simulations

International audienceDecision making for environmental issues increasingly relies on numerical simulations and various observational data. However, the numerical models are limited by strong uncertainties because of poor input data and inaccurate physical, chemical, biological or mathematical modeling. Moreover, measurement instruments do not allow for a complete observation of environmental systems, and they often acquire noisy observations. Nevertheless, there is a strong need to optimally and jointly exploit numerical simulations and field observations for an objective assessment of risks on present and future times.In this context, it is critical to quantify the uncertainties of all information sources (numerical models, empirical rules, fixed observations, mobile observations, qualitative observations) and to evaluate the best estimates that are derived from all the information. The final scientific products that may help decision-making are the probability distribution of the target quantities, confidence intervals or probabilistic forecasts.These various products can be derived from ensembles of simulations possibly combined with observations by the so-called data assimilation methods. The ensembles can be calibrated, including for the forecasts, in order to approximate the distribution of simulation errors. Such methods are for instance operationally applied for weather forecasting. The distribution of ensembles can be processed for a better quantification of the uncertainty. It is for instance possible to derive risk maps. Practical applications, like the protection of populations after a nuclear disaster as in Fukushima, can benefit from such risk maps, e.g., to determine an evacuation zone

Les recherches contemporaines en géographie rurale : territoires, ressources et pratiques du terrain

International audienceCe texte est une synthèse des réflexions partagées par les doctorants présents lors d'une journée organisée à Montpellier, le 26 mars 2009, par la commission française de géographie rurale. Il pose la question de la spécificité des recherches géographiques sur les espaces ruraux à partir de trois entrées épistémologiques et méthodologiques : le territoire, les ressources et la pratique du terrain. Les regards croisés des huit contributeurs, enrichis de leurs propres expériences de recherche et d'une journée commune de terrain, montrent que les problèmes de délimitation des territoires d'étude, de caractérisation des ressources locales et de méthodologie d'investigation préoccupent les jeunes chercheurs géographes

Data assimilation of OMI NO2 observations for improving air quality forecast over Europe

This paper concerns the improvements of NO2 forecast due to satellite data assimilation. The Ozone Monitoring Instrument (OMI) aboard NASA Aura satellite provides observations of NO2 columns for air quality study. These satellite observations are assimilated, with the optimal-interpolation method, in an air quality model from Polyphemus, in order to improve NO2 forecasts in Europe. Good consistency is seen in the comparisons of model simulations, satellite data and ground observations before assimilation. The model results with and without assimilation are then compared with ground observations for evaluating the assimilation effects. It is found that in winter the errors between model data and ground observations have been reduced after assimilation, indicating a better NO2 forecast can be obtained using satellite observations. Such improvements are not found in summer, which is probably due to the shorter life time and higher temporal variability of NO2 in the warmer season

Congenital and Disseminated Pyogenic Granuloma-like Vascular Lesions

International audienceWe report an exceptional case of multiple cutaneous and visceral neonatal pyogenic granuloma (PG) initially suggestive of a diffuse neonatal haemangiomatosis. CASE REPORT A full-term female newborn, with no significant past medical history, was referred to our department for treatment of an acute respiratory distress syndrome of neurological origin at day 8 of life. At birth, she presented with 3 small angiomatous papules and 4 subcutaneous nodules suggestive of neonatal hae-mangiomatosis (NH) (Fig. 1). A brain MRI revealed a highly vascularised brain stem tumour suggestive of glioma (Fig. 2), associated with 2 abnormal hepatic lesions consistent with infantile haemangiomas (IH) on ultrasound and CT scan. Methylprednisolone was started for the suspected glioma-associated oedema, and vincristine and propranolol were introduced for NH. After initial improvement, an acute intracranial hypertension related to cystic evolution of the disease necessitated surgical resection at the age of 2 months. Pathological examinations of the brain, cutaneous and subcutaneous lesions were similar, showing a vascular lobular proliferation of capillaries highly suggestive of PG. The misdiagnosis of glioma was eliminated. The GLUT-1 antigen marker was negative, ruling out the diagnosis of NH-like infantile haemangioma (Fig. 3). Lymphatic marker (D2-40) was also negative and eliminated a multifocal lymphangioendotheliomato-sis with thrombocytopaenia (MLT). Cutaneous and hepatic lesions gradually regressed. She is currently in complete remission after completing a treatment over 18 months with propranolol but a spontaneous improvement can not be excluded. DISCUSSIO

Prevalence of inherited ichthyosis in France: a study using capture-recapture method

International audienceBACKGROUND:Inherited ichthyoses represent a group of rare skin disorders characterized by scaling, hyperkeratosis and inconstant erythema, involving most of the tegument. Epidemiology remains poorly described. This study aims to evaluate the prevalence of inherited ichthyosis (excluding very mild forms) and its different clinical forms in France.METHODS:Capture - recapture method was used for this study. According to statistical requirements, 3 different lists (reference/competence centres, French association of patients with ichthyosis and internet network) were used to record such patients. The study was conducted in 5 areas during a closed period.RESULTS:The prevalence was estimated at 13.3 per million people (/M) (CI95%, [10.9 - 17.6]). With regard to autosomal recessive congenital ichthyosis, the prevalence was estimated at 7/M (CI 95% [5.7 - 9.2]), with a prevalence of lamellar ichthyosis and congenital ichthyosiform erythroderma of 4.5/M (CI 95% [3.7 - 5.9]) and 1.9/M (CI 95% [1.6 - 2.6]), respectively. Prevalence of keratinopathic forms was estimated at 1.1/M (CI 95% [0.9 - 1.5]). Prevalence of syndromic forms (all clinical forms together) was estimated at 1.9/M (CI 95% [1.6 - 2.6]).CONCLUSIONS:Our results constitute a crucial basis to properly size the necessary health measures that are required to improve patient care and design further clinical studies

Isolation and characterization of mesotrione-degrading Bacillus sp. from soil

International audienceDissipation kinetics of mesotrione, a new triketone herbicide, sprayed on soil from Limagne (Puy-de-Dôme, France) showed that the soil microflora were able to biotransform it. Bacteria from this soil were cultured in mineral salt solution supplemented with mesotrione as sole source of carbon for the isolation of mesotrione-degrading bacteria. The bacterial community structure of the enrichment cultures was analyzed by temporal temperature gradient gel electrophoresis (TTGE). The TTGE fingerprints revealed that mesotrione had an impact on bacterial community structure only at its highest concentrations and showed mesotrione-sensitive and mesotrione-adapted strains. Two adapted strains, identified as Bacillus sp. and Arthrobacter sp., were isolated by colony hybridization methods. Biodegradation assays showed that only the Bacillus sp. strain was able to completely and rapidly biotransform mesotrione. Among several metabolites formed, 2-amino-4-methylsulfonylbenzoic acid (AMBA) accumulated in the medium. Although sulcotrione has a chemical structure closely resembling that of mesotrione, the isolates were unable to degrade i

COVID-19 Vaccinations: Perceptions and Behaviours in People with Primary Ciliary Dyskinesia.

Primary ciliary dyskinesia (PCD) is a rare genetic disease that causes recurrent respiratory infections. People with PCD may be at higher risk of severe coronavirus disease 2019 (COVID-19), and therefore vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is important. We studied vaccination willingness, speed of vaccination uptake, side effects, and changes in social contact behaviour after vaccination in people with PCD. We used data from COVID-PCD, an international participatory cohort study. A COVID-19 vaccination questionnaire was emailed to participants in May 2021 and 423 participants from 31 countries replied (median age: 30 years, range 1–85 years; 261 (62%) female). Vaccination uptake and willingness were high, with 273 of 287 adults (96%) being vaccinated or willing to be in June 2021; only 4% were hesitant. The most common reason for hesitancy was fear of side effects, reported by 88%. Mild side effects were common, but no participant reported severe side effects. Half of the participants changed their social behaviour after vaccination by seeing friends and family more often. The high vaccination willingness in the study population might reflect the extraordinary effort taken by PCD support groups to inform people about COVID-19 vaccination. Clear and specific information and involvement of representatives is important for high vaccine uptake
