Peter Christian Jacobsen (éd. et trad.), Die Geschichte vom Leben des Johannes, Abt des Klosters Gorze

En 2009, Peter Christian Jacobsen éditait et traduisait les « Miracles » écrits en l’honneur de saint Gorgon (ainsi que d’autres textes complémentaires), qui constituent une source importante pour comprendre la réforme de Gorze, effectuée vers 934 sous l’impulsion de l’évêque Adalbéron Ier de Metz (Miracula s. Gorgonii. Studien und Texte zur Gorgonius-Verehrung im 10. Jahrhundert, 2009). Son volume fut disponible quelques semaines avant la parution, en France, d’une autre édition de ces mêmes..

Jessika Nowak, Jens Schneider et Anne Wagner (dir.), Ein Raum im Umbruch? Herrschaftsstrategien in Besançon im Hochmittelalter

Ce volume s’intéresse à l’espace autour de Besançon, correspondant principalement à l’archidiocèse bisontin : cette zone de rencontre à cheval entre la région rhénane et la vallée du Rhône, entre le Jura, la plaine suisse et la France du Nord, constitua un territoire disputé entre plusieurs royaumes, une « province-carrefour », selon l’expression de Michel Chevalier (« Le cadre géographique de Besançon », in Claude Fohlen (dir.), Histoire de Besançon, vol. 1 : Des origines à la fin du XVIe si..

Klaus Herbers, Harald Müller (dir.), Lotharingien und das Papsttum im Früh- und Hochmittelalter

Le volume s’ouvre par un rapide Vorwort, dans lequel Klaus Herbers et Harald Müller reviennent sur la particularité de la Lotharingie comme « espace de l’entre-deux », notamment du point de vue des éditions diplomatiques. En effet, le « Göttinger Papsturkunden-Werk », a pour objectif, depuis 1896, d’établir une édition critique des actes pontificaux antérieurs à Innocent III (1198–1216), qui sont à recenser dans les archives de leurs destinataires, alors qu’à partir du pontificat de ce dernie..

Alexis Wilkin et Jean-Louis Kupper (dir.), Évêque et prince. Notger et la Basse-Lotharingie aux alentours de l’an Mil

Ce livre est issu d’un colloque qui s’est tenu en 2008 à l’Université de Liège à l’occasion du millénaire de la mort de Notger, fondateur de la principauté épiscopale de Liège et source d’inspiration intarissable pour l’historiographie belge, comme l’explique dès l’introduction Jean-Louis Kupper. En 1905, Godefroid Kurth publiait son Notger de Liège et la civilisation au xe siècle, qui fait encore référence aujourd’hui. Depuis, de nombreux articles, un ouvrage (Notger et Liège : l’an mil au c..

Covipendium : information available to support the development of medical countermeasures and interventions against COVID-19

The living paper on the new coronavirus disease (COVID-19) provides a structured compilation of scientific data about the virus, the disease and its control. Its objective is to help scientists identify the most relevant publications on COVID-19 in the mass of information that appears every day. It is also expected to foster a global understanding of disease control and stimulate transdisciplinary initiatives

Community-Level Responses to Iron Availability in Open Ocean Plankton Ecosystems

Predicting responses of plankton to variations in essential nutrients is hampered by limited in situ measurements, a poor understanding of community composition, and the lack of reference gene catalogs for key taxa. Iron is a key driver of plankton dynamics and, therefore, of global biogeochemical cycles and climate. To assess the impact of iron availability on plankton communities, we explored the comprehensive bio-oceanographic and bio-omics data sets from Tara Oceans in the context of the iron products from two state-of-the-art global scale biogeochemical models. We obtained novel information about adaptation and acclimation toward iron in a range of phytoplankton, including picocyanobacteria and diatoms, and identified whole subcommunities covarying with iron. Many of the observed global patterns were recapitulated in the Marquesas archipelago, where frequent plankton blooms are believed to be caused by natural iron fertilization, although they are not captured in large-scale biogeochemical models. This work provides a proof of concept that integrative analyses, spanning from genes to ecosystems and viruses to zooplankton, can disentangle the complexity of plankton communities and can lead to more accurate formulations of resource bioavailability in biogeochemical models, thus improving our understanding of plankton resilience in a changing environment

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

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
