💫Another interesting decision in favor of #GIs. The producer group in charge of the AOC “Côtes de Provence” succeeded in transfer of a registered domain name to itself, which was consisted of the same words as the name of this GI. You can read the summary of my article about this #Afnic decision published on the oriGIn, the Organization for an international Geographical Indications network. https://lnkd.in/eG-hiZui #intellectualproperty #geographicalindications #cotesdeprovence #domainnames #ADR #AOP #AOC #IGP

🚀#TitleStory 🔹Isospin-Symmetry Breaking within the Nuclear Shell Model: Present Status and Developments, Review by Nadezda A. Smirnova https://lnkd.in/g_KzrpN8 Université de Bordeaux; CNRS Centre de Physique des Particules de Marseille (CPPM; CNRS/IN2P3 - Aix-Marseille University); MDPI This article belongs to the Special Issue The Nuclear Shell Model 70 Years after Its Advent: Achievements and Prospects (https://lnkd.in/dAtgbDyi) #nuclear #shellmodel #isospin #symmetry #physics #Abstract The paper reviews the recent progress in the description of isospin-symmetry breaking within the nuclear shell model and applications to actual problems related to the structure and decay of exotic neutron-deficient nuclei and nuclei along the 𝑁=𝑍 line, where N is the neutron number and Z the atomic number. The review recalls the fundamentals of the isospin formalism for two-nucleon and many-nucleon systems, including quantum numbers, the spectrum’s structure and selection rules for weak and electromagnetic transitions; and at the end, summarizes experimental signatures of isospin-symmetry breaking effects, which motivated efforts towards the creation of a relevant theoretical framework to describe those phenomena. The main approaches to construct accurate isospin-nonconserving Hamiltonians within the shell model are briefly described and recent advances in the description of the structure and (isospin-forbidden) decay modes of neutron-deficient nuclei are highlighted. The paper reviews major implications of the developed theoretical tools to (i) the fundamental interaction studies on nuclear decays and (ii) the estimation of the rates of nuclear reactions that are important for nuclear astrophysics. The shell model is shown to be one of the most suitable approaches to describing isospin-symmetry breaking in nuclear states at low energies. Further efforts in extending and refining the description to larger model spaces, and in developing first-principle theories to deal with isospin-symmetry breaking in many-nucleon systems, seem to be indispensable steps towards our better understanding of nuclear properties in the precision era.

📣 This year’s edition of the interdisciplinary #UniGR_CBS online lecture series “Border Realities” will start in October in cooperation with the Université Grenoble Alpes. The lecture series will deal with #borders and the nature-culture divide: Anthropogenic climate change and its consequences have eroded the Western paradigm of separating humans from Nature and Nature from Culture. In this context, it becomes imperative to reconsider the interdependencies between humans and the living world. The international speakers will address: ◾ Natural borders and the naturalization of borders ◾ The roles of nonhumans in bordering processes  ◾ Posthuman approaches to #borders ◾ The connection and difference between biological and political borders ◾ Bordering and #climatechange ◾ Borders and nature conservation The 2024/2025 edition of "Border Realities" is organized and chaired by Lola Aubry (UniGR-CBS, University of Luxembourg) and Anne-Laure Amilhat-Szary (Laboratoire Pacte, CNRS, Université Grenoble Alpes). The online UniGR-CBS lecture series #BorderRealities is open to join and aimed at researchers, students, and the interested public.

BISE ? For What ? The BISE team is one of the six research team of the Earth and Environment Institute of Strasbourg (ITES: Unité Mixte de Recherche Institut Terre et Environnement de Strasbourg sous les tutelles du CNRS, de l'Université de Strasbourg et de l'ENGEES). The BISE project aims to understand and trace the reactive processes in the Critical Zone (CZ) of the Earth under gradual climatic anthropogenic forcing. The CZ corresponds to the thin layer of the Earth, from the top of the canopy to the base of deep aquifers, which is the most deeply impacted by the human activities, but also the one that provides nutrients to the biosphere and therefore plays an essential role in sustaining life on the planet. The scientific motivation of BISE is to contribute to knowledge and understanding of the complex interactions between the physical, chemical and biological processes that control the matter transfer between continental ecosystems and their response to environmental and anthropogenic pressures. Beyond the scientific knowledge, this project also addresses societal issues, in conjunction with non-academic partners, in the fields of water and soils management in forestry, agricultural and urban catchments, with a focus on the biogeochemical cycles of nutrients and the transfer and transformation of pollutants.   The methodological foundations of BISE rely on a quantitative, transverse and integrated approach based on matter flows measurements from the laboratory to the catchment scale, and the development of geochemical tracers and numerical models

Scientific analysis unveils a secret in Leonardo da Vinci's Mona Lisa. On October 11, researchers from the CNRS revealed findings from a study on a fragment of Leonardo da Vinci’s Mona Lisa, uncovering a rare compound that sheds new light on the techniques behind this masterpiece. Da Vinci—known not only as a painter but also as a draftsman, sculptor, architect, engineer, and, as it turns out, a chemist—has surprised the world again. A study published by the CNRS, in collaboration with the European Synchrotron Radiation Facility (ESRF), the Louvre, and the French Ministry of Culture, analyzed a fragment from the underlayer of the Mona Lisa. According to their findings in the Journal of the American Chemical Society, da Vinci experimented with a rare compound known as lead monacite. The presence of this compound suggests he used a unique blend of lead-based oil, setting it apart from typical oil paint mixtures of that era. X-ray revelations of the Mona Lisa: The discovery began with an earlier investigation. Following research on lead-based white pigments at France's Center for Research and Restoration of Museums, chemist Victor Gonzalez found lead monacite in certain works by Rembrandt. Its presence hints at the use of lead oxide in a high-pH environment, prompting experts to re-examine iconic Louvre artworks using advanced X-ray technology at the ESRF. This method enables precise analysis of microscopic paint fragments, and in 2007, the researchers identified lead monacite within an underlayer of the Mona Lisa, in an area hidden by the frame. Historical use of lead white pigment: Although this compound does not appear in other da Vinci works housed at the Louvre, it has been found in The Last Supper, his mural in the Santa Maria delle Grazie convent in Milan. Leonardo wrote extensively about his observations, but researchers found no direct mention of lead white (then called "litharge") in painting techniques. Marine Cotte, ESRF chemist, found that the term appears under the spelling “letargirio di piombo” in a manuscript referring to a remedy for skin and hair care. This discovery confirmed that da Vinci was familiar with lead oxide, which may have influenced his painting resources. A chemical innovation to perfect paint application: According to scientists, da Vinci may have been experimenting with a lead-oil mixture (a blend of oil paint and lead oxide) to accelerate drying, increase texture flexibility, and ease paint application. This thicker layer would help him conceal surface imperfections. The hypothesis suggests that he first tested this siccative formula in The Last Supper, creating a method suitable for murals, which he later adapted on a smaller scale for the wood panel in the Mona Lisa. This breakthrough underscores Leonardo's innovative approach and resourcefulness as an artist. #artcollecting #artexhibition #artmuseum #artcollector #artnews #artworld #artmarket #artmarketnews #arthistory https://lnkd.in/e2YwQySQ

"Returning migrants can bring home the fertility norms they encountered while abroad." Simone Bertoli at CERDI Université Clermont Auvergne CNRS IRD writes in this IZA World of Labor article: ''Does return migration influence fertility at home?' #returnmigration #norms #fertility Elevator pitch Demographic factors in migrant-sending countries can influence international migration flows. But when migrants move across borders, they can also influence the pace of demographic transition in their countries of origin. This is because migrants, who predominantly move on a temporary basis, encounter new fertility norms in their host countries and then bring them back home. These new fertility norms can be higher or lower than those in their country of origin. So the new fertility norms that result from migration flows can either accelerate or slow down a demographic transition in migrant-sending countries. https://lnkd.in/dbXiE59

[ 🚨 PSSD-IELM SEMINAR - April 29TH 🚨 ] 📆 On Monday, the #PSSD-#IELM Research Seminar will welcome Gregory Corcos, from École Polytechnique. 🖥 Gregory Corcos will present a talk on "Firm-level export and import survival over the business cycle". 📍 The research #seminar will take place at 11:00am (Paris time), in the 6th floor room of Maison des Sciences Economiques, Université Paris 1 Panthéon-Sorbonne and will also be held online by Zoom. 👨‍🏫 Gregory Corcos is an associate professor at the Department of Economics of Ecole polytechnique. 🔍 His #research interests are in #internationaleconomics especially international trade with a focus on the decisions and organization of exporting and importing firms. 📜 Abstract: This paper examines how business cycle conditions affect the dynamics of exporting and importing firms, using micro-level data on trade spells initiated by French firms over the period 1998-2015. First, we find evidence of firm reallocation during recessions. Entry rates fall while exit rates increase. Both entrants and exiters exhibit higher productivity, suggesting tougher selection into export and import participation. Second, business cycle conditions at times of entry have persistent effects on exporters and importers: cohorts ’born’ in recessions have a systematically lower exit rate at any age. They also exhibit persistently different characteristics from firms that enter in better times. In the case of exports, cohorts born at recessions and booms display a similar age-dependence path. In other words, firms entering export markets in a recession enjoy a one-off premium to their spell duration prospects. Third, conclusions are largely unaffected when we use a joint model of export and import duration. Our estimates reveal a positive correlation in the unobservable factors explaining both decisions. To put it simply, exporters-importers tend to have either short-short or long-long spells. Overall, our results suggest that business cycle conditions affect trade participation in the short- and long-run, with recessions having both ’cleansing’ and ’scarring’ effects. 👉 Gregory's website: https://lnkd.in/ekf94Bqm 👉 PSSD-IELM website: https://cutt.ly/JwzsG4SG 👉 Zoom link: https://lnkd.in/gazSW7g7

[ 🚨 PSSD-IELM SEMINAR - MAY 27TH 🚨 ] 📆 On Monday, the #PSSD-#IELM Research Seminar will welcome Isabelle Mejean, from Sciences Po. 🖥 Isabelle Mejean will present a talk on "#Carbon #Border #Adjustments at the Extensive Margin" (with P. Coster and J. di Giovanni). 📍 The research #seminar will take place at 11:00am (Paris time), in the 6th floor room of Maison des Sciences Economiques, Université Paris 1 Panthéon-Sorbonne and will also be held online by Zoom. 👨‍🏫 Isabelle Mejean is Professor at the Sciences Po economics department. 🔍 Her #research interests are in #InternationalMacroeconomics and #Trade 📜 Abstract: A prevailing consensus among economists asserts that establishing a sufficiently high carbon price serves as a fundamental pillar for tackling climate change, and that this pricing should be implemented on a global scale to prevent carbon leakage. In this paper, we model firms' import decisions of dirty and clean intermediate inputs, and ask how those decisions are altered by carbon price policies. We first use a triple difference strategy to show that French firms' propensity to import dirty inputs from outside of the EU has increased in the 2010s, when ETS was getting more binding. Second, we develop a model of import sourcing displaying clean and dirty inputs, origin-specific fixed costs of importing and country-specific carbon policies. The model is estimated on pre-ETS data. We then use the estimated model to run counterfactuals mimicking the current ETS system, covering production in the European Union, and an ETS system augmented with a carbon border adjustment that expands carbon taxation to non-European productions. We show that the unilateral policy can reproduce the level of carbon leakage observed in the data while CBAM neutralize this source of carbon leakage. 👉 Isabelle's website: https://lnkd.in/eyZidH39 👉 PSSD-IELM website: https://cutt.ly/JwzsG4SG 👉 Zoom link: https://lnkd.in/gazSW7g7
