High-resolution laser system for the S3-Low Energy Branch
In this paper we present the first high-resolution laser spectroscopy results
obtained at the GISELE laser laboratory of the GANIL-SPIRAL2 facility, in
preparation for the first experiments with the S-Low Energy Branch. Studies
of neutron-deficient radioactive isotopes of erbium and tin represent the first
physics cases to be studied at S. The measured isotope-shift and hyperfine
structure data are presented for stable isotopes of these elements. The erbium
isotopes were studied using the atomic transition (415 nm) and the tin isotopes were studied by
the atomic transition (286.4
nm), and are used as a benchmark of the laser setup. Additionally, the tin
isotopes were studied by the
atomic transition (811.6 nm), for which new isotope-shift data was obtained and
the corresponding field-shift and mass-shift factors are
presented
How genomics can help biodiversity conservation
The availability of public genomic resources can greatly assist biodiversity assessment, conservation, and restoration efforts by providing evidence for scientifically informed management decisions. Here we survey the main approaches and applications in biodiversity and conservation genomics, considering practical factors, such as cost, time, prerequisite skills, and current shortcomings of applications. Most approaches perform best in combination with reference genomes from the target species or closely related species. We review case studies to illustrate how reference genomes can facilitate biodiversity research and conservation across the tree of life. We conclude that the time is ripe to view reference genomes as fundamental resources and to integrate their use as a best practice in conservation genomics.info:eu-repo/semantics/publishedVersio

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19
IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.
Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.
DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 nonâcritically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).
INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (nâ=â257), ARB (nâ=â248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; nâ=â10), or no RAS inhibitor (control; nâ=â264) for up to 10 days.
MAIN OUTCOMES AND MEASURES The primary outcome was organ supportâfree days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.
RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ supportâfree days among critically ill patients was 10 (â1 to 16) in the ACE inhibitor group (nâ=â231), 8 (â1 to 17) in the ARB group (nâ=â217), and 12 (0 to 17) in the control group (nâ=â231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ supportâfree days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).
CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

DĂ©composition de Helmholtz-Hodge d'un champ de vitesse "Bas Mach"
This video displays the Helmholtz-Hodge decomposition of a velocity field obtained for an axisymmetric, laminar, Low Mach flow of a hot air jet in an enclosure initially filled with cold air. The decomposition of the field allows us to isolate the irrotational part of the velocity field linked to pressurization of the enclosure, from the solenoidal part, with zero divergence, associated with vortices. Each part of the field is associated with a potential. These two potentials are scalar under the axisymmetric hypothesis.From left to right in the video:1) The velocity field ;2-3) The potential and velocity field associated with the irrotational part;4-5) The potential and velocity field associated with the solenoidal part.The numerical method used to perform the decomposition is a quadratic Q2 finite element method implemented in the Cast3M software.Cette vidéo montre la décomposition de Helmholtz-Hodge d'un champ de vitesse obtenu pour un écoulement, supposé axisymétrique, laminaire et Bas Mach, d'un jet d'air chaud dans une enceinte initialement remplie d'air froid. La décomposition du champ permet d'isoler la partie du champ de vitesse, irrotationnelle, liée à la pressurisation de l'enceinte de celle, solénoïdale, à divergence nulle, associée aux tourbillons. Chaque partie du champ est associée à un potentiel. Ces deux potentiels sont scalaires dans le cadre de l'hypothÚse axisymétrique.De gauche à droite sur la vidéo :1) Le champ de vitesse ;2-3) Le potentiel et le champ de vitesse associées à la partie irrotationnelle ;4-5) Le potentiel et le champ de vitesse associées à la partie solénoïdale.La méthode numérique utilisée pour effectuer la décomposition est une méthode d'éléments finis quadratiques Q2 implémentée dans le code de calcul Cast3M
