Direct Exoplanet Detection using Convolutional Image Reconstruction (ConStruct): A New Algorithm for Post-processing High-contrast Images
Authors: Wolf Trevor N. , Jones Brandon A. , Bowler Brendan P. 
Published: February 2024

Abstract
We present a novel machine-learning approach for detecting faint point sources in high-contrast adaptive optics (AO) imaging data sets. The most widely used algorithms for primary subtraction aim to decouple bright stellar speckle noise from planetary signatures by subtracting an approximation of the temporally evolving stellar noise from each frame in an imaging sequence. Our approach aims to improve the stellar noise approximation and increase the planet detection sensitivity by leveraging deep learning in a novel direct imaging post-processing algorithm. We show that a convolutional autoencoder neural network, trained on an extensive reference library of real imaging sequences, accurately reconstructs the stellar speckle noise at the location of a potential planet signal. This tool is used in a post-processing algorithm we call Direct Exoplanet Detection with Convolutional Image Reconstruction, or ConStruct. The reliability and sensitivity of ConStruct are assessed using real Keck/NIRC2 angular differential imaging data sets. Of the 30 unique point sources we examine, ConStruct yields a higher signal-to-noise ratio than traditional principal component analysis-based processing for 67% of the cases and improves the relative contrast by up to a factor of 2.6. This work demonstrates the value and potential of deep learning to take advantage of a diverse reference library of point-spread function realizations to improve direct imaging post-processing. ConStruct and its future improvements may be particularly useful as tools for post-processing high-contrast images from JWST and extreme AO instruments, both for the current generation and those being designed for the upcoming 30 m class telescopes.
Effects of Heliolatitudinal Anisotropy of Solar Far-ultraviolet/Extreme-ultraviolet Emissions on Lyα Helioglow
Authors: Strumik M. , Bzowski M. , Kubiak M. A. 
Published: February 2024

Abstract
We present a study of the influence of solar UV anisotropy on the heliospheric backscatter helioglow generated by resonant scattering of solar Lyα photons on interstellar hydrogen atoms around the Sun. Simulations based on the WawHelioGlow model suggest that the response of the helioglow pole-to-ecliptic ratio to the anisotropy is linear, but 15% of the anisotropy (polar darkening) generates 30%–40% change in the ratio in the solar minimum and 15%–20% in the solar maximum. We attribute this difference to an interplay between the solar UV anisotropy and the latitudinal structure of the solar wind in solar minima. The solar UV anisotropy also increases the helioglow intensity from the downwind direction by 5%–10%, due to the influence of the anisotropy on the ionization losses and trajectories of atoms passing by the Sun in polar regions. Consequently, midlatitude regions (in the heliographic and ecliptic coordinates) are least affected by the UV anisotropy. By comparison of the simulation results with observations of the Solar and Heliospheric Observatory/SWAN satellite instrument, we derive the day-by-day time evolution of the solar Lyα anisotropy for the north and south poles over two solar cycles from 1996 to 2022. The inferred anisotropy is ∼5%–10% in solar minima and ∼15%–25% in solar maxima, the northern anisotropy being stronger than the southern one. Our study suggests that in solar minima a highly structured solar wind is associated with relatively small solar UV anisotropy, while in solar maxima the solar wind is more isotropic but a substantial solar UV anisotropy appears.

Abstract
Heartbeat stars (HBSs) with tidally excited oscillations (TEOs) are ideal laboratories for studying the effect of equilibrium and dynamical tides. However, studies of TEOs in Kepler HBSs are rare due to the need for better modeling of the equilibrium tide in light curves. We revisit the HBSs in our previous work and study the TEOs in these HBSs based on the derived orbital parameters that could express the equilibrium tide. We also compile a set of analytic procedures to examine the harmonic and anharmonic TEOs in their Fourier spectra. The TEOs of 21 HBSs have been newly analyzed and presented. Twelve of these HBSs show prominent TEOs (signal-to-noise ratio of the harmonics S/N ≥ 10). The relation between the orbital eccentricities and the harmonic number of the TEOs shows a positive correlation. The relation between the orbital periods and the harmonic number also shows a positive correlation. Furthermore, the distribution of HBSs with TEOs in the Hertzsprung–Russell diagram shows that TEOs are more visible in hot stars with surface effective temperatures T ≳ 6500 K. These samples may also be valuable targets for future studies of the effect of tidal action in eccentric orbits.
Large-scale Anisotropy of Galactic Cosmic Rays as a Probe of Local Cosmic-Ray Propagation
Authors: Li Ai-feng , Yuan Qiang , Liu Wei , Guo Yi-qing 
Published: February 2024

Abstract
Recent studies have shown that the anisotropy is of great value to decipher cosmic rays’ origin and propagation. We have built a unified scenario to describe the observations of the energy spectra and the large-scale anisotropy and called attention to their synchronous evolution with energy. In this work, the impact of the local regular magnetic field (LRMF) and corresponding anisotropic diffusion on large-scale anisotropy have been investigated. When the perpendicular diffusion coefficient is much smaller than the parallel one, the dipole anisotropy points to the LRMF and the observational phase below 100 TeV could be reproduced. Moreover, we find that the dipole phase above 100 TeV strongly depends on the evolution of local diffusion. But the current measurements at that energy are still scarce. We suggest that more precise measurements at that energy could be carried out to unveil the local diffusion and further the local turbulence.
Rapid Chemical Enrichment by Intermittent Star Formation in GN-z11
Authors: Kobayashi Chiaki , Ferrara Andrea 
Published: February 2024

Abstract
We interpret the peculiar supersolar nitrogen abundance recently reported by the James Webb Space Telescope observations for GN-z11 (z = 10.6) using our state-of-the-art chemical evolution models. The observed CNO ratios can be successfully reproduced—independently of the adopted initial mass function, nucleosynthesis yields, and presence of supermassive (>1000M
⊙) stars—if the galaxy has undergone an intermittent star formation history with a quiescent phase lasting ∼100 Myr, separating two strong starbursts. Immediately after the second burst, Wolf–Rayet stars (up to 120M
⊙) become the dominant enrichment source, also temporarily (<1 Myr) enhancing particular elements (N, F, Na, and Al) and isotopes (13C and 18O). Alternative explanations involving (i) single burst models, also including very massive stars and/or pair-instability supernovae, or (ii) pre-enrichment scenarios fail to match the data. Feedback-regulated, intermittent star formation might be common in early systems. Elemental abundances can be used to test this hypothesis and to get new insights on nuclear and stellar astrophysics.
Predicting the Timing of the Solar Cycle 25 Polar Field Reversal
Authors: Jha Bibhuti Kumar , Upton Lisa A. 
Published: February 2024

Abstract
The process of the Sun’s polar field cancellation reversal commences with the emergence of new cycle Hale’s polarity active regions. Once the Sun undergoes polarity reversal, typically occurring near the peak of solar activity, it begins the process of accumulating the seed field for the forthcoming solar cycle. In recent years, the advective flux transport (AFT) model has proven highly effective in forecasting the progression of polar fields by leveraging observations of surface flows and magnetic flux emergence. In this study, we make use of the predictive capability of the AFT model to simulate the evolution of the polar fields and estimate the timing of the Solar Cycle 25 polarity reversal in both hemispheres of the Sun. We use the statistical properties of active regions along with Solar Cycle 13, which closely resembles the current solar cycle (Cycle 25), to generate synthetic active regions in order to simulate future magnetic flux emergence in AFT to predict the evolution of the polar field. Based on our simulations, we anticipate that the northern hemisphere of the Sun will undergo a polarity reversal between 2024 June and November, with the center of our distribution at 2024 August. In the southern hemisphere, we anticipate a polarity reversal between 2024 November and 2025 July, centered around 2025 February. Additionally, assuming that the reversal of the axial dipole moment coincides with the peak of the solar cycle, our findings indicate that Cycle 25 is expected to peak in 2024 (likely between 2024 April and August).

As part of the Oriental Biogeographical Region, Indonesia has recorded the presence of freshwater shrimp in various areas, taking into consideration that these animals are beneficial both ecologically and economically. Even so, the fact is that data on the existence of freshwater shrimp in Indonesia still need to be included in some areas, as well as in Belitung Island. Information recording of a species is necessary so that its existence is easier to protect. This study describes the freshwater shrimp species found in Belitung Island.
Here, we present new distribution records of eight species of freshwater shrimp (Crustacea, Decapoda, Palaemonidae) from Belitung Island, Indonesia. In addition to the morphological description, each species is also provided with the nucleotide sequence of the CO1 gene. All species belong to the genus Macrobrachium.

Biodiversity conservation is an important goal of most ecosystem management efforts. Therefore, proper monitoring of biodiversity requires constant attention. Coleoptera should be monitored as an essential part of the overall biodiversity. Special monitoring is needed for families that are active as predators (e.g. Coccinellidae) or are saproxylic species (e.g. Elateridae and Cerambycidae). The aim of the research is to describe the fauna of seven families of Coleoptera (Elateridae, Drilidae, Lycidae, Lampyridae, Cantharidae, Coccinellidae and Cerambycidae) of the Republic of Mordovia (the centre of the European part of Russia). The results are based on faunistic research, the main part of which was carried out in April-October 2007-2023 and on material from museum collections. The collecting was made using several different methods (by hand, light trapping, on different lures, into pitfall traps etc.). GPS coordinates are given for each faunistic record.
The dataset contains information on seven species new to the region: Malthodes flavoguttatus Kiesenwetter, 1852, Malthodes minimus (Linnaeus, 1758) (Cantharidae); Scymnus rubromaculatus (Goeze, 1777) (Coccinellidae); Anoplodera rufipes ventralis Heyden, 1886, Tragosoma depsarium (Linnaeus, 1767), Xylotrechus arvicola (Olivier, 1795) and Xylotrechus ibex (Gebler, 1825) (Cerambycidae).
Le pire n’est jamais certain

Published: February 2024

D’où vient qu’une pratique sublimatoire, incertaine par nature, essence et définition, tire son auteur du côté de la mélancolie ou à l’inverse du côté du plaisir ? La réponse a à faire avec l’acceptation de la limitation de la toute-puissance, et l’investissement du changement. Les propositions sont ici argumentées à partir de divers exemples tirés essentiellement de la littérature.
Une solitude habitée, la figure de l’entre-deux
Authors: Dollé-Monglond Brigitte 
Published: February 2024

L’auteure met l’accent sur la théorisation de la pensée de l’analyste en séance, et sur le fil central de la solitude qui l’accompagne dans ses différentes déclinaisons : présence-absence, vivance-perte, en partant de La perte de soi de J.-F. Chiantaretto, et des associations qu’il lui a inspirées. Elle explore ainsi une solitude habitée, animée par un entre-deux qui singularise l’expérience de la cure, tandis qu’elle est traversée par des mouvements intérieurs contradictoires entre doutes et conviction, incertitudes et croyance, et prolongée pour l’analyste par la place de l’écriture.
Le féminin selon François Perrier : une mise en question de toute loi-cadre sur le féminin
Authors: Filloux Janine 
Published: February 2024

Dans le « Séminaire sur l’amour » (1970-1971), François Perrier apporte une contribution essentielle à la problématique de la sexualité féminine et du féminin en donnant au maternel féminin statut d’expérience fondatrice du féminin, de la construction du narcissisme et du moi-idéal pour la femme, en deçà de la théorie sexuelle phallique soutenue par Freud assignant à la femme valeur de négatif. À l’écoute clinique des contenus pulsionnels archaïques, d’angoisses féminines spécifiques, non partageables par le garçon, il récuse le schéma freudien réduisant l’accès au désir chez la femme à l’envie du pénis. Avec l’invention du concept d’amatride comme structure de transition dans la culture, il décrit et conceptualise une figure féminine illustrant une faillite de la structuration du féminin pour donner à la cure la visée d’inscrire le signifiant féminin dans sa positivité.

Published: February 2024

• Objectif L’objectif de cette étude est de présenter l’approche méthodologique computationnelle ancrée qui repose sur une démarche d’interprétation par les chercheurs des thèmes détectés par les algorithmes d’intelligence artificielle (IA) puis de l’appliquer au cas #Movember. • Méthodologie Une classification non supervisée par LDA et une analyse de sentiment ont été réalisées sur 144 906 tweets provenant de différents pays participants (France, Italie, Belgique, Australie, USA, UK, Arabie Saoudite, etc.). • Résultats Les résultats montrent que le processus de l’engagement individuel au mouvement social #Movember est composé de trois principaux éléments : (1) 4 segments d’engagement individuel (sympathisants, conscients, engagés et maintiens), (2) émotions collectives (positives et négatives) et (3) facteurs cognitifs et motivationnels (calcul bénéfices-coûts, efficacité collective et identité). • Implications managériales Les résultats proposent des actions marketing adaptées à chaque segment pour aider à la fois les organisateurs du mouvement #Movember et les professionnels de santé (PS) à atteindre deux principaux objectifs : (1) dépistage et (2) notoriété, recrutement et collecte de dons, grâce au big data, par le ciblage des personnes avec antécédents familiaux. • Originalité Les recherches sur #Movember utilisent habituellement les algorithmes supervisés qui présentent plusieurs limites tels que biais de confirmation, manque de répétabilité et une exigence en temps. Ce travail utilise le modèle non supervisé LDA pour identifier des concepts latents par la machine dans une perspective computationnelle ancrée (Computational Grounded Theory, CGT).
Regards anthropologiques et métaphysiques croisés sur l’histoire de l’âme végétante : l’exemple de l’opposition de Jean-Baptiste de la Quintinie aux conceptions cartésiennes de la croissance des plantes
Authors: Bertrand Aliénor 
Published: February 2024

Cet article propose une méthode de lecture par l’exemple du corpus de philosophie et de littérature modernes sur les plantes. Il mobilise différentes disciplines comme l’anthropologie des savoirs et l’histoire des sciences, mais aussi la métaphysique et l’anthropologie de la nature à partir de l’étude des Réflexions sur l’agriculture de J.-B. de la Quintinie. L’analyse porte sur la défense d’un principe vital ordonnant la croissance végétale, puis sur le statut ontologique des plantes et enfin, sur les aspects les plus métaphysiques de l’opposition de La Quintinie au principe de l’abandon de l’âme nutritive, qui se trouvent liés à la fois à sa théorie de fructification et à ses pratiques de la nature.

Succédant aux polyptyques médiévaux, certains retables modernes ont été pourvus d’un mécanisme permettant d’exposer successivement différents tableaux d’autel. Cet article aborde les raisons qui motivèrent le changement des peintures et le rythme selon lequel il s’opérait, en étudiant l’histoire des cycles et leur iconographie. Prenant en compte les travaux les plus récents ainsi que de nouvelles découvertes en archives, le corpus d’étude – dont le répertoire est annexé en ligne – permet d’interroger la dimension spectaculaire de ces dispositifs comme l’implication des Jésuites dans sa diffusion.
Pourquoi l’industrie japonaise de la construction navale résiste-t-elle aujourd’hui à la concurrence chinoise et sud-coréenne ?
Authors: Barjot Dominique 
Published: February 2024

Aujourd’hui, l’industrie mondiale de la construction navale est dominée par trois nations asiatiques : la Chine (environ 40 % du marché), la Corée du Sud (environ 30-35 %) et le Japon (20-25 %). Depuis la fin des années 1950, ces trois pays se sont succédé à la tête du marché mondial. Grâce à la révolution du transport maritime, mais aussi de la marine militaire, dès les années 1880, le Japon s’est progressivement imposé comme l’une des premières puissances navales avant de supplanter le Royaume-Uni à partir du milieu des années 1950. Jusqu’à la fin des années 1990, il a affirmé son leadership, avant de s’effacer au cours de la décennie suivante au profit de la Corée du Sud, puis, depuis le début des années 1990, derrière la Chine. Néanmoins, et malgré des coûts de production plus élevés, le Japon a conservé des parts de marché importantes. Il a même réussi à regagner de meilleures positions (29 % des nouvelles commandes en 2015), notamment face à la Chine puis à la Corée du Sud. La construction navale a non seulement été l’un des secteurs phares de l’industrialisation japonaise sur le long terme, mais encore elle reste également compétitive grâce à une très forte capacité d’innovation technologique, à l’importance de la flotte marchande japonaise, à des restructurations spectaculaires (notamment autour de Mitsubishi Heavy Industries) et à la supériorité technologique mondiale de l’industrie sidérurgique nationale.
