Poster Abstract:Deploying a 6LoWPAN, CoAP, low power, wireless sensor network

In order to integrate equipment from different vendors, wireless sensor networks need to become more standardized. Using IP as the basis of low power radio networks, together with application layer standards designed for this purpose is one way forward. This research focuses on implementing and deploying a system using Contiki, 6LoWPAN over an 868 MHz radio network, together with CoAP as a standard application layer protocol. A system was deployed in the Cairngorm mountains in Scotland as an environmental sensor network, measuring streams, temperature profiles in peat and periglacial features. It was found that RPL provided an effective routing algorithm, and that the use of UDP packets with CoAP proved to be an energy efficient application layer. This combination of technologies can be very effective in large area sensor networks

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

La psilocybine (de son utilisation ancienne au cours de rituels chamaniques à sa consommation récréative actuelle en passant par son intérêt pharmaceutique)

Après avoir définie et replacée la psilocybine au sein de la classification chimique des substances psychoactives, nous débuterons par une description de son emploi historique au cours des rituels et cérémonies chamaniques pratiqués par les civilisations précolombiennes d'Amérique centrale. Nous poursuivrons l'étude en identifiant l'utilisation moderne, à but récréatif et sociabilisant de la substance psychédélique. Nous constaterons alors la simplicité d'accès au produit bien que sa consommation et sa détention soient illégales puisqu'il s'agit d'un stupéfiant. Après avoir détaillée une liste non exhaustive de champignons, parmi plus de deux cent espèces renfermant la psilocybine, nous aborderons la chimie avec l'analyse des méthodes d'identification, puis les propriétés de la substance et de ses dérivés. Suite à l'étude structurale, nous traiterons la pharmacologie de la molécule. Pour finir, nous verrons que la psilocybine, à dose pharmacologique et dans un cadre maîtrisé, peut être utilisée à but thérapeutiqueLYON1-BU Santé (693882101) / SudocSudocFranceF

Budget 2020 : What effects on households?

Budget 2020:What effects on households?This policy brief analyzes the redistributive effects of the social and fiscal policy measures for households coming into force in 2020. Our results highlight an average gain of 1% in disposable income for the 60% of households located in the middle of the income distribution, with a standard of living between €1,274 and €2,803 per month. These increases in disposable income for the middle classes are partly explained by the latest wave of housing tax cuts. The income tax cut is the other important measure of the 2020 budget, and leads to greater gains for households above the median, with a standard of living above €1,778 per month. The poorest 8% of households, below €837 per month, and the wealthiest 5% of households, above €4,034 per month, are little affected by the socio–fiscal measures coming into force in 2020. We then analyze the effect of all the measures coming into force between 2018 and 2020. We observe gains in disposable income for a majority of households, with a maximum of 3.2% of disposable income between the 25th and 75th standard-of-living percentile (including households with a standard of living between €1,274 and €2,435 per month). Only the poorest households, below €789 per month, do not benefit on average from these measures. The wealthiest 1% of households, above €6,880 per month, see their disposable income increase by 2.2%, with an effect of 3.9% for the wealthiest 0.1% of households with a standard of living above €18,689 per month

Modal parameter variability in industrial electric guitar making: Manufacturing process, wood variability, and lutherie decisions

International audienceRecent studies showed that mechanical coupling between structure and strings can alter the sound of the solid body electric guitar. Modal frequencies and damping ratios of the structure can explain some sound differences between instruments. These vibratory parameters can vary because of lutherie decisions (e.g. intentionally fitting guitars with different woods for sound quality purposes), wood intrinsic variability, or making process variability. Yet the vast majority of solid body electric guitars comes from an industrial mass-production: the manufacturing process is designed for producing guitars that are the most similar possible. However, musicians and makers know that guitars of the same model both share features, and still have some individual properties. The experimental quantification of the modal parameter variability of nominally identical electric guitars in an industrial context is the aim of this article. This variability is assessed on one guitar set, and compared to other industrial objects. A second guitar set is investigated: it consists of guitars with maple or rosewood fingerboard, all other specifications being identical. This second set allows the comparison between making process and wood variability, with the variability due to an intentional lutherie decision: the change of the fingerboard wood

Quelles leçons tirer des réformes de la fiscalité des revenus du capital ?

International audienceLa suppression du prélèvement forfaitaire libératoire (PFL) en 2013 et l’introduction du prélèvement forfaitaire unique (PFU) en 2018 sont deux réformes importantes – de sens contraire – de la fiscalité des revenus du capital. La première visait à « rétablir la justice fiscale » quand la seconde visait à « soutenir l’investissement privé ». Nous exploitons les données fiscales des ménages et des entreprises pour mener une évaluation d’impact de la réforme de 2013, et présentons des premiers éléments concernant l’impact de la réforme de 2018.Nous obtenons un impact négatif très fort de l’augmentation de la fiscalité des revenus du capital sur les dividendes reçus par les ménages et un impact nul pour les autres revenus (salaires, plus-values et autres revenus du capital). En utilisant les données d’entreprise, nous parvenons à identifier le mécanisme expliquant cette baisse des dividendes reçus : les entreprises contrôlées directement par des personnes physiques résidant en France ont réduit, ou stoppé, la distribution de dividendes entre 2013 et 2017. On observe une augmentation des actifs financiers détenus au sein de ces entreprises, une hausse des fonds propres ainsi qu’une baisse du résultat net, mais aucun effet sur l’investissement.Les implications de ces résultats sont majeures : la réforme de 2013 a engendré une perte nette de recettes fiscales, mais aucun impact négatif sur l’investissement. Avec les données des greffes des tribunaux de commerce, nous mettons en évidence une hausse des dividendes versés en 2018 de 15,3% attribuable à la réforme du PFU. Cette augmentation de la distribution des dividendes, parallèle à la baisse de 2013, conduira à des recettes fiscales plus importantes qu’anticipé initialement. Cependant, au vu des effets de la réforme de 2013, il est probable qu’aucun effet positif sur l’investissement privé ne soit à attendre de cette réforme
