description: We present explicit expressions for Rayleigh and Raman scattering cross-sections and phase matrices of the ground $1s$ state hydrogen atom based on the Kramers-Heisenberg dispersion formula. The Rayleigh scattering leaves the hydrogen atom in the ground-state while the Raman scattering leaves the hydrogen atom in either $ns$ ($n\geq2$; $s$-branch) or $nd$ ($n\geq3$; $d$-branch) excited state, and the Raman scattering converts incident ultraviolet (UV) photons around the Lyman resonance lines into optical-infrared (IR) photons. We show that this Raman wavelength conversion of incident flat UV continuum in dense hydrogen gas with a column density of $N_{\text{H}} > 10^{21}~\text{cm}^{-2}$ can produce broad emission features centred at Balmer, Paschen, and higher-level lines, which would mimic Doppler-broadened hydrogen lines with the velocity width of $\gtrsim 1,000~\text{km}~\text{s}^{-1}$ that could be misinterpreted as signatures of Active Galactic Nuclei, supernovae, or fast stellar winds. We show that the phase matrix of the Rayleigh and Raman $s$-branch scatterings is identical to that of the Thomson scattering while the Raman $d$-branch scattering is more isotropic, thus the Paschen and higher-level Raman features are depolarized compared to the Balmer features due to the flux contribution from the Raman $d$-branch. We argue that observations of the line widths, line flux ratios, and linear polarization of multiple optical/IR hydrogen lines are crucial to discriminate between the Raman-scattered broad emission features and Doppler-broadened emission lines.

Validation des indicateurs écologiques de qualité des nourriceries (sole, groupe 0 et peuplement associé) et recherche d'optimisation dans l'optique d'un reseau d'observation à l'échelle du Golfe de Gascogne. Test sur un site " nouveau ", le secteur Nord d'Arcachon. Echantillonnage de juvéniles de soles du groupe 2 (avant leur première migration vers les aires des adultes) pour établir leur signature microchimique, à relier aux échantillonnages qui devront être réalisés au cours de la saison de reproduction suivante (premier trimestre 2004, campagne à prevoir) sur les aires de frayères. Les nourriceries cotiêres ont été prospectées entre les fonds de 5 mètres (limites d'accessibilité du Gwen Drez) et les fonds de 25 mètres (marge externe des nourriceries). Les prélevements standardisés consistent en chalutages à perche (CP3M, chalut de 3 mètres de large, maillage de 10 mm de cote, durée 15 minutes); les échantillons biologiques nécessitant des chalutages avec un plus grand engin (CV, chalut 25 m de type vendéen avec double poche en 10 ou 20 mm de cote, durée 30 a 45 minutes). Les chalutages à perche ont été traités selon le protocole standard (manuel des protocoles Desaunay et Guérault, 2002). Toutes les espèces prélevées ont été identifiées et dénombrées, tous les poissons d'interêt halieutique mesurés. Concernant la sole, 708 paires d'otolithes ont été prélevées pour les déterminations de classes annuelles, plus de 600 individus ont été conservés pour les analyses de microchimie.Les relevés d'hydrologie (température et salinité) ont été saisis.Les projets de rattachement sont PNEC, chantier Gascogne, Défi golfe de Gascogne.

description: Determinant quantum Monte Carlo (DQMC) is a widely used unbiased numerical method for simulating strongly correlated electron systems. However, the update process in DQMC is often a bottleneck for its efficiency. To address this issue, we propose a generalized delay update scheme that can handle both onsite and extended interactions. Our delay update scheme can be implemented in both zero-temperature and finite-temperature versions of DQMC. We apply the delay update scheme to various strongly correlated electron models and evaluate its efficiency under different conditions. Our results demonstrate that the proposed delay update scheme significantly improves the efficiency of DQMC simulations, enable it to simulate larger system size.

description: Foundation structures for offshore wind turbines are typically made of heavy plate structural steels, such as S420ML, welded by submerged arc welding. Due to the welding process conditions, higher amounts of hydrogen can be introduced. In this context, large plate thicknesses result in long diffusion paths and a prolonged diffusion time for hydrogen at ambient temperature and possible delayed hydrogen-assisted cold cracking. As a result, hydrogen can accumulate in areas of high mechanical stress and strain. Due to the delayed diffusion, a minimum waiting time of up to 48 h must be observed before nondestructive testing can be performed. In addition, the assessment of possible cold crack locations is very complex. For this reason, a numerical model of a component-like weld test was developed to simulate the temperature field during welding and subsequent cooling. A hydrogen diffusion model based on the temporal-local temperature distribution was established. It was applied to simulate the change of hydrogen distribution as a function of temperature cycle during multi-layer welding and further for the entire waiting time interval ≤ 48 h. As a result, crack critical areas could be evaluated in terms of accumulated hydrogen. An advantage of the diffusion model is the simulation of a normalized concentration, i.e. between "0" (no hydrogen) and "1" (max. concentration), which can be scaled to experimentally determined hydrogen concentrations. Finally, selected results for increased real hydrogen ingress are presented, which confirm the relatively high crack resistance of the S420 submerged arc welded joint.

description: In the unique institutional context of the Court of Justice of the European Union, what could and should be the place of artificial intelligence (AI) in legal translation? To answer that question, it is necessary to understand the parameters within which the Court’s legal translation service operates, and the choices that have been made in respect of multilingualism in the face of a growing workload, budgetary restrictions, and the Court’s obligation to maintain the functioning of EU justice. It is equally important to understand the Court’s institutional position on AI, how AI is currently used within the legal translation service, and the challenges AI currently poses. The future of AI in legal translation at the Court will depend not only on technological progress and the specificities of the EU’s multilingual framework, but also on a careful assessment in relation to the desired translation output, the methods used in its production, and the impact of AI’s growing role on human resources. In spite of its current limitations and unpredictable future, AI has the potential to enhance rapid multilingual access to EU justice and case-law and contribute to a ‘beneficial’ future. This is a matter of importance for all those subject to EU law, given the ex-tent to which AI can be abused and the climate of rising nationalism within and beyond the EU.

Generative Bayesian modeling to nowcast the effective reproduction number from line list data with missing symptom onset dates

description: The time-varying effective reproduction number $R_t$ is a widely used indicator of transmission dynamics during infectious disease outbreaks. Timely estimates of $R_t$ can be obtained from observations close to the original date of infection, such as the date of symptom onset. However, these data often have missing information and are subject to right truncation. Previous methods have addressed these problems independently by first imputing missing onset dates, then adjusting truncated case counts, and finally estimating the effective reproduction number. This stepwise approach makes it difficult to propagate uncertainty and can introduce subtle biases during real-time estimation due to the continued impact of assumptions made in previous steps. In this work, we integrate imputation, truncation adjustment, and $R_t$ estimation into a single generative Bayesian model, allowing direct joint inference of case counts and $R_t$ from line list data with missing symptom onset dates. We then use this framework to compare the performance of nowcasting approaches with different stepwise and generative components on synthetic line list data for multiple outbreak scenarios and across different epidemic phases. We find that under long reporting delays, intermediate smoothing, as is common practice in stepwise approaches, can bias nowcasts of case counts and $R_t$, which is avoided in a joint generative approach due to shared regularization of all model components. On incomplete line list data, a fully generative approach enables the quantification of uncertainty due to missing onset dates without the need for an initial multiple imputation step. In a real-world comparison using hospitalization line list data from the COVID-19 pandemic in Switzerland, we observe the same qualitative differences between approaches. Our generative modeling components have been integrated into the R package epinowcast.

description: Observations of anomalies in the electron-positron angular correlations in high-energy decays in $^4$He, $^8$Be, and $^{12}$C have been reported recently by the ATOMKI collaboration. These could be explained by the creation and subsequent decay of a new boson with a mass of ${\sim}17$ MeV. Theoretical understanding of pair creation in the proton capture reactions used in these experiments is important for the interpretation of the anomalies. We apply the ab initio No-Core Shell Model with Continuum (NCSMC) to the proton capture on $^7$Li. The NCSMC describes both bound and unbound states in light nuclei in a unified way with chiral two- and three-nucleon interactions as the only input. We investigate the structure of $^8$Be, the $p+^7$Li elastic scattering, the $^7$Li($p,γ$)$^8$Be cross section and the internal pair creation $^7$Li($p,e^+ e^-$)$^8$Be. We discuss the impact of a proper treatment of the initial scattering state on the electron-positron angular correlation spectrum and compare our results to available ATOMKI data sets. Finally, we calculate $^7$Li($p,X$)$^8$Be cross sections for several proposed models of the hypothetical X17 particle.

description: This study examined the associations of long-term exposure to ambient fine particulate matter (PM2.5) compositions/ozone with methylation of peripheral brain-derived neurotrophic factor (BDNF) promoters. A total of 101 participants were recruited from a cohort in Shijiazhuang, Hebei province, China. They underwent baseline and follow-up surveys in 2011 and 2015. DNA methylation levels were detected by bisulfite-PCR amplification and pyrosequencing. Participants‘ three-year average levels of PM2.5 compositions and ozone were estimated. Bayesian kernel machine regression (BKMR) models were used to examine the joint effects of pollutants on methylation levels. Exposure to PM2.5 compositions and ozone mixtures at the 75th percentile was associated with increased methylation levels at CpG2 of BDNF promoter (203%, 95% CI: 89, 316) than the lowest level of exposure, and sulfate dominated the effect in the BKMR models.Our findings provide clues to the epigenetic mechanisms for the associations of PM2.5 compositions and ozone with BDNF.

description: Our study aimed to identify and verify G protein-related methylated genes in AIT patients, while also investigate those genes in AIT patients exposed to iodine in different water iodine areas. Different areas were classified by median water iodine (MWI) concentrations: Iodine-Fortified Areas (IFA, MWI<10µg/L), Iodine-Adequate Areas (IAA, 40≤MWI≤100 µg/L), and Iodine-Excessive Areas (IEA, MWI>100 µg/L). We studied 176 AIT cases and 176 controls, with 89, 40, and 47 pairs in IFA, IAA, and IEA, respectively. Using the Illumina Human Methylation 850k BeadChip, we identified candidate methylated genes. MethylTargetTM and QRT-PCR validated DNA methylation and mRNA expression. Results showed hypomethylation and high expression of RAB8A and RAP1A in all 176 AIT cases. RAB8A's CpG sites were mainly hypomethylated in IFA and IEA, while RAP1A's sites were primarily hypomethylated in IEA. This study underscores how water iodine exposure may influence RAB8A and RAP1A methylation in AIT.

description: Les zones d'estuaires et de deltas sont cruciales dans la compréhension et la quantification du rôle de l'océan dans le cycle du carbone. Ces régions sont caractérisées par de très forts gradients spatiaux liés aux apports des fleuves. En effet, dans les systèmes de delta, la matière particulaire est exportée dans le panache fluvial et sédimente rapidement pour s'accumuler dans les sédiments, donnant lieu à un couplage pélagique-benthique important. Le recyclage de la matière organique et inorganique dans les sédiments superficiels participe à la régulation des flux de carbone et de nutriments dans la zone côtière. Du fait de l'activité humaine dans les bassins fluviaux, les conditions environnementales des deltas sont souvent dégradées par l'hypoxie ou l'acidification côtière. Ces dysfonctionnements rendent ces systèmes vulnérables, ainsi que les services écosystémiques qu'ils apportent. Dans le delta du Rhône, la dynamique biogéochimique du recyclage dans les zones anoxiques du sédiment qui participe aux flux d'alcalinité et donc à la régulation des échanges de carbone océan-atmosphère, est mal connue.Lors de la campagne MissRhoDia2, nous avons étudié le recyclage de la matière particulaire issue du fleuve et de la production marine avec une attention particulière sur les sédiments anoxiques et sur l'interaction carbone organique/carbone inorganique dans les sédiments du delta. Ces travaux cruciaux pour la compréhension de la diagenèse sédimentaire ont été entrepris en période de fin de printemps afin de poursuivre le travail entrepris lors de la campagne DICASE (Juin 2014).La campagne s'est donc déroulée en Mai 2018 avec pour objectifs principaux :- Etudier les processus anoxiques et oxiques dans les sédiments du prodelta du Rhône et mesurer les flux d'échange in situ à l'aide d'incubations de carottes.- Etudier le recyclage du carbone organique et inorganique déposé dans les sédiments en mettant l'accent sur la régulation de l'acidification notamment par l'interaction carbone organique/carbone inorganique, ainsi que les flux d'alcalinité générés par les processus oxiques, anoxiques et l'interaction dissous-particulaire.Les séries de résultats issues des campagnes DICASE, AMOR-BFlux et MissRhoDia2 seront combinées afin d'apporter des informations sur le couplage pélagique-benthique, les transferts de carbone inorganique et d'alcalinité des sédiments vers la mer côtière et l'influence sur les flux de CO2. Ils sont en cours de valorisation dans le cadre d'une thèse en cours au LSCE (L. Brethous) et serviront à calibrer un modèle avancé de diagenèse développé dans le cadre de cette thèse.Cette campagne a utilisé des technologies avancées basées sur des mesures in situ et ex situ : profileur autonome LSCE, incubation de carotte, station benthique du LSCE. Ces mesures ont été calibrées et complétées par des techniques classiques : extraction d'eaux interstitielles sous azote, prélèvement d'eau sur stations par bouteille Niskin.

description: La campagne MOBIDYC3 est une campagne de vibro sondage dont l'objectif essentiel est lacorrélation des corps sédimentaires, mis en évidence par nos précédentes missions de sismique marine (missions MOBIDYC1- 2000, MOBIDYC2- 2001, SIFADO-1999, NOMADES-2000, DSIRe-2001), avecdes faciès sédimentaires. La zone d'étude correspond aux Pertuis Charentais qui sont des segments de vallées incisees ennoyées. Deux types de corps sédimentaires ont été sondés lors de la campagne MOBIDYC3 : (1) Des corps dont les caractéristiques géométriques permettent de penser qu'il s'agit d'enregistrements de périodes de plus bas niveaux marins (marqueurs du dernier intervalle transgressif) ; (2) des corps sédimentaires actifs (bancs de sable, vagues de sable, couverture arilo-silteuse) qui enregistrentla dynamique actuelle.

description: Kinetic traps are a notorious problem in equilibrium statistical mechanics, where temperature quenches ultimately fail to bring the system to low energy configurations. Using multifarious self-assembly as a model system, we introduce a mechanism to escape kinetic traps by utilizing non-reciprocal interactions between components. Introducing non-equilibrium effects offered by broken action-reaction symmetry in the system, we can push the trajectory of the system out of arrested dynamics. The dynamics of the model is studied using tools from the physics of interfaces and defects. Our proposal can find applications in self-assembly, glassy systems and systems with arrested dynamics.

description: L'objectif spécifique de cette campagne est la quantification des volumes de sédiments meubles et remobilisables dans la zone d'avant plage du sud de l'île d'Oléron et du Pertuisde Maumusson. Les résultats préliminaires d'une de nos campagnes de levés sismiques, réalisée dans la passe de Maumusson (Août, 2001), montre une incision, fortement marquée, du socle mésozoïque, immédiatement au nord de la passe. Or, nous pensons que cette incision est un réservoir de sédiments meubles qui peut en partie expliquer des échanges sédimentaires depuis le domaine d'avant-plage vers les côtes. Il est donc fondamental de pouvoir restituer la géométrie tridimentionnelle de cette incision afin d'estimer le volume de sédiments meuble potentiellement mobilisable pour les échanges entre l'avant-plage et la côte.

description: To investigate the relationship between fluoride exposure and Osteochondroma (OC) prevalence, a cross-sectional study was conducted in drinking water endemic fluorosis areas of Heilongjiang Province, China. Our study first reported that the prevalence of OC was 2.3% in drinking water endemic fluorosis areas of Heilongjiang Province, China, and no difference in gender. Logistic regression analysis found that compared to 1st quartile participants, the prevalence of OC was 73% lower in the 2nd quartile participants of WF (Water fluoride), and 3.4 times higher among the 2nd quartile UF (Urinary fluoride) participants. Our study suggests that 0.259–0.420 mg/L of WF may be considered an appropriate level for reducing OC prevalence, while UF (≥0.750 mg/L) could slightly increase the prevalence of OC. In summary, the link between fluoride and OC prevalence is complicated and needs to be further investigated in a cohort population.

description: While the existing literature on Differential Privacy (DP) auditing predominantly focuses on the centralized model (e.g., in auditing the DP-SGD algorithm), we advocate for extending this approach to audit Local DP (LDP). To achieve this, we introduce the LDP-Auditor framework for empirically estimating the privacy loss of locally differentially private mechanisms. This approach leverages recent advances in designing privacy attacks against LDP frequency estimation protocols. More precisely, through the analysis of numerous state-of-the-art LDP protocols, we extensively explore the factors influencing the privacy audit, such as the impact of different encoding and perturbation functions. Additionally, we investigate the influence of the domain size and the theoretical privacy loss parameters $ε$ and $δ$ on local privacy estimation. In-depth case studies are also conducted to explore specific aspects of LDP auditing, including distinguishability attacks on LDP protocols for longitudinal studies and multidimensional data. Finally, we present a notable achievement of our LDP-Auditor framework, which is the discovery of a bug in a state-of-the-art LDP Python package. Overall, our LDP-Auditor framework as well as our study offer valuable insights into the sources of randomness and information loss in LDP protocols. These contributions collectively provide a realistic understanding of the local privacy loss, which can help practitioners in selecting the LDP mechanism and privacy parameters that best align with their specific requirements. We open-sourced LDP-Auditor in \url{https://github.com/hharcolezi/ldp-audit}.

description: Rectification effects in solid-state devices are a consequence of nonreciprocal transport properties. This phenomenon is usually observed in systems with broken inversion symmetry. In most instances, nonreciprocal transport arises in the presence of an applied magnetic field and the rectified signal has an antisymmetric dependence on the field. We have observed rectification of environmental electromagnetic fluctuations in plain Nb channels without any asymmetry in design, leading to spontaneous voltage peaks at the superconducting transition. The signal is symmetric in the magnetic field and appears even without an applied field at the critical temperature. This is indicative of an unconventional mechanism of nonreciprocal transport resulting from a spontaneous breaking of inversion symmetry.

description: L'objectif principal de MOBIDYC5 est de généraliser la corrélation sismique Très Haute Résolution / résultats de carottages dans les zones à très forte sédimentation (> 1 cm/an), afin de mettre en évidence un enregistrement sédimentaire des changements environnementaux récents (depuis 2000 BP environ). Il s'agira donc de réaliser des carottages, les plus proches possibles de profils sismiques THR (de résolution décimétrique), dans des zones où l'accrétion sédimentaire est de plus de 2 m lors des 200 dernières années. Un objectif complémentaire consistera à comparer les résultats des sondages avec la sismique THR dans le but de mieux corréler les changements granulométriques avec les variations de réflectivité. Pour atteindre cet objectif il est prévu de réaliser des sondages le long d'un profil montrant des variations latérales de réflectivité le long d'un même horizon acoustique.Le troisième objectif sera de prélever des sédiments dans les zones sourdes qui correspondent à des accumulations de gaz (Bertin et Chaumillon, sous presse). Ces prélèvements permettront de réaliser des analyses chimiques et biologiques afin de connaître la nature des gaz accumulés et les organismes qui les produisent. Le programme de rattachement est le Programme National Environnement Côtier (PNEC).

description: The paper represents a first exploratory study based on the comparison between the Weighted Average Cost of Capital (WACC) of a sample of companies listed on Malaysian Stock Exchange, classified and shared according to the principles of Islamic finance (i.e. riba, risk sharing, haram).

In particular, the main aim of the analysis is to provide some evidences of the potential effect on the risk (measured by beta) on the WACC as result of the principles used to divide the companies between Shari’ah Compliant and not Shari’ah Compliant. Generally our findings are focused on a greater level of WACC related to the LCSC that belong to the majority of selected sectors and, according to the principles of Islamic finance, they have shown a leverage ratio lower than that of companies not Shari’ah Compliant.

description: The use of pesticide use has been linked to the higher production of reactive oxygen species, resulting in oxidative stress, which in turn can cause genomic instability. A marker for instability is the copy number variation of the mitochondrial genome (mtDNAcn), which has been found to be altered in diverse human diseases, including tumors. This research aimed to examine the variation of mtDNAcn in individuals occupationally exposed to pesticides. Real-time PCR assays were conducted on 154 individuals (78 exposed and 76 non-exposed). Pesticide-exposed ndividuals exhibited a significant reduction in mtDNAcn (1.11 ± 0.37mtDNAcn/genome) compared to non-exposed individuals (1.30 ± 0.33mtDNAcn/genome; p = 0.001). The multivariate analysis indicated that individuals who reported using haloxyfop and copper sulfate demonstrated an increase (β = 0.200, p = 0.053) and a decrease (β=-0.2, p = 0.021), respectively, in mtDNAcn. In conclusion, our findings suggest that chronic exposure to pesticides results in changes in mtDNAcn.

description: In delocalized systems, particle number fluctuations, also known as quantum surface roughness, and the mean-square displacement exhibit a temporal power-law growth followed by a saturation to a system-size-dependent value. We use simple scaling arguments to show that these quantities satisfy the Family-Vicsek scaling law and derive a dynamic scaling relation between the dynamical exponents, assuming that the saturation times of both quantities scale similarly with the system size. This relation clarifies the mechanism behind quantum surface roughness growth and suggests that diffusive quantum many-body systems belong to the Edwards-Wilkinson universality class. Moreover, it provides a convenient way to assess quantum transport in cold-atom experiments. We numerically verify our results by studying two non-interacting models and one interacting model having regimes with distinct dynamical exponents.
