Subgroup detection in linear growth curve models with generalized linear mixed model (GLMM) trees
Authors: Fokkema Marjolein , Zeileis Achim 
Published: May 2024

AbstractGrowth curve models are popular tools for studying the development of a response variable within subjects over time. Heterogeneity between subjects is common in such models, and researchers are typically interested in explaining or predicting this heterogeneity. We show how generalized linear mixed-effects model (GLMM) trees can be used to identify subgroups with different trajectories in linear growth curve models. Originally developed for clustered cross-sectional data, GLMM trees are extended here to longitudinal data. The resulting extended GLMM trees are directly applicable to growth curve models as an important special case. In simulated and real-world data, we assess performance of the extensions and compare against other partitioning methods for growth curve models. Extended GLMM trees perform more accurately than the original algorithm and LongCART, and similarly accurate compared to structural equation model (SEM) trees. In addition, GLMM trees allow for modeling both discrete and continuous time series, are less sensitive to (mis-)specification of the random-effects structure and are much faster to compute.
Estimating the proportions and latencies of reaction time outliers: A pooling method and case study of lexical decision tasks
Authors: Miller Jeff 
Published: May 2024

AbstractA methodological problem in most reaction time (RT) studies is that some measured RTs may be outliers—that is, they may be very fast or very slow for reasons unconnected to the task-related processing of interest. Numerous ad hoc methods have been suggested to discriminate between such outliers and the valid RTs of interest, but it is extremely difficult to determine how well these methods work in practice because virtually nothing is known about the actual characteristics of outliers in real RT datasets. This article proposes a new method of pooling cumulative distribution function values for examining empirical RT distributions to assess both the proportions of outliers and their latencies relative to those of the valid RTs. As the method is developed, its strengths and weaknesses are examined using simulations based on previously suggested ad hoc models for RT outliers with particular assumed proportions and distributions of valid RTs and outliers. The method is then applied to several large RT datasets from lexical decision tasks, and the results provide the first empirically based description of outlier RTs. For these datasets, fewer than 1% of the RTs seem to be outliers, and the median outlier latency appears to be approximately 4–6 standard deviations of RT above the mean of the valid RT distribution.
Katachi (形): Decoding the Imprints of Past Star Formation on Present-day Morphology in Galaxies with Interpretable CNNs*

Abstract
The physical processes responsible for shaping how galaxies form and quench over time leave imprints on both the spatial (galaxy morphology) and temporal (star formation history; SFH) tracers that we use to study galaxies. While the morphology–SFR connection is well studied, the correlation with past star formation activity is not as well understood. To quantify this, we present Katachi (形), an interpretable convolutional neural network framework that learns the connection between the factors regulating star formation in galaxies on different spatial and temporal scales. Katachi is trained on 9904 galaxies at 0.02 < z < 0.1 in the SDSS-IV MaNGA DR17 sample to predict stellar mass (M
*; root mean square error (RSME) 0.22 dex), current star formation rate (SFR; RMSE 0.31 dex), and half-mass time (t
50; RMSE 0.23 dex). This information allows us to reconstruct nonparametric SFHs for each galaxy from gri imaging alone. To quantify the morphological features informing the SFH predictions, we use SHAP (SHapley Additive exPlanations). We recover the expected trends of M
* governed by the growth of galaxy bulges, as well as those of SFR correlating with spiral arms and other star-forming regions. We also find that the SHAP maps of D4000 are more complex than those of M
* and SFR, and that morphology is correlated with t
50 even at fixed mass and SFR. Katachi serves as a scalable public framework to predict galaxy properties from large imaging surveys including Rubin, Roman, and Euclid, with large data sets of high signal-to-noise ratio imaging across limited photometric bands.
Relation between the Local Width and Linear Halo Mass Density of Cosmic Filaments
Authors: Zhu Weishan , Wang Tian-Rui , Zhang Fupeng , Zheng Yi , Feng Long-Long 
Published: May 2024

Abstract
Large-scale cosmic filaments may have played an important role in shaping the properties of galaxies. Meanwhile, cosmic filaments are believed to harbor a substantial portion of the missing baryons at redshift z < 2. To inspect the role of filaments in these issues, many properties of filaments need to be examined, including their lengths, thicknesses, and density profiles. However, measuring some of these properties poses challenges. This study concentrates on estimating filament width/thickness, investigating potential correlations between the local width of filaments and the properties of dark matter halos within filaments. We find that the local width of filaments generally increases with the mass of dark matter halos embedded in filaments per unit length, roughly following a second-order polynomial, although with notable scatter. We probe and discuss means that may refine our findings. After further verification and improvements, this relation could be applied to filament samples constructed from the observed galaxy distribution, aiding in understanding the roles of cosmic filaments in galaxy evolution and uncovering the missing baryons.
Strong Fractionation of Deuterium and Helium in Sub-Neptune Atmospheres along the Radius Valley

Published: May 2024

Abstract
We simulate atmospheric fractionation in escaping planetary atmospheres using IsoFATE, a new open-source numerical model. We expand the parameter space studied previously to planets with tenuous atmospheres that exhibit the greatest helium and deuterium enhancement. We simulate the effects of extreme-ultraviolet-driven photoevaporation and core-powered mass loss on deuterium–hydrogen and helium–hydrogen fractionation of sub-Neptune atmospheres around G, K, and M stars. Our simulations predict prominent populations of deuterium- and helium-enhanced planets along the upper edge of the radius valley with mean equilibrium temperatures of ≈370 K and as low as 150 K across stellar types. We find that fractionation is mechanism dependent, so constraining He/H and D/H abundances in sub-Neptune atmospheres offers a unique strategy to investigate the origin of the radius valley around low-mass stars. Fractionation is also strongly dependent on retained atmospheric mass, offering a proxy for planetary surface pressure as well as a way to distinguish between desiccated enveloped terrestrials and water worlds. Deuterium-enhanced planets tend to be helium dominated and CH4 depleted, providing a promising strategy to observe HDO in the 3.7 μm window. We present a list of promising targets for observational follow-up.

Published: May 2024

Abstract
We present the discovery of 13 new widely separated T dwarf companions to M dwarf primaries, identified using Wide-field Infrared Survey Explorer/NEOWISE data by the CatWISE and Backyard Worlds: Planet 9 projects (hereafter BYW). This sample represents an ∼60% increase in the number of known M + T systems, and allows us to probe the most extreme products of binary/planetary system formation, a discovery space made available by the CatWISE2020 catalog and the BYW effort. Highlights among the sample are WISEP J075108.79-763449.6, a previously known T9 thought to be old due to its spectral energy distribution, which was found by Zhang et al. (2021b) to be part of a common proper motion pair with L34-26 A, a well-studied young M3 V star within 10 pc of the Sun; CWISE J054129.32-745021.5 B and 2MASS J05581644-4501559 B, two T8 dwarfs possibly associated with the very fast-rotating M4 V stars CWISE J054129.32745021.5 A and 2MASS J05581644-4501559 A; and UCAC3 52-1038 B, which is among the widest late-T companions to main-sequence stars, with a projected separation of ∼7100 au. The new benchmarks presented here are prime JWST targets, and can help us place strong constraints on the formation and evolution theory of substellar objects as well as on atmospheric models for these cold exoplanet analogs.
Modified Temperature–Redshift Relation and Ultra-high-energy Cosmic Ray Propagation

Published: May 2024

Abstract
We reexamine the interactions of ultra-high-energy cosmic rays (UHECRs) with photons from the cosmic microwave background (CMB) under a changed, locally nonlinear temperature–redshift relation T(z). This changed temperature–redshift relation has recently been suggested by the postulate of subjecting thermalized and isotropic photon gases such as the CMB to an SU(2) rather than a U(1) gauge group. This modification of ΛCDM is called SU(2)CMB, and some cosmological parameters obtained by SU(2)CMB seem to be in better agreement with local measurements of the same quantities, in particular H
0 and S8. In this work, we apply the reduced CMB photon density under SU(2)CMB to the propagation of UHECRs. This leads to a higher UHECR flux just below the ankle in the cosmic ray spectrum and slightly more cosmogenic neutrinos under otherwise equal conditions for emission and propagation. Most prominently, the proton flux is significantly increased below the ankle (5 × 1018 eV) for hard injection spectra and without considering the effects of magnetic fields. The reduction in CMB photon density also favors a decreased cosmic ray source evolution than the best fit using ΛCDM. In consequence, it seems that SU(2)CMB favors sources that evolve like the star formation rate, such as starburst galaxies and gamma-ray bursts, over active galactic nuclei as origins of UHECRs. We conclude that the question about the nature of primary sources of UHECRs is directly affected by the assumed temperature–redshift relation of the CMB.
Skeletal Kinetics Reduction for Astrophysical Reaction Networks

Published: May 2024

Abstract
A novel methodology is developed to extract accurate skeletal reaction models for nuclear combustion. Local sensitivities of isotope mass fractions with respect to reaction rates are modeled based on the forced optimally time-dependent (f-OTD) scheme. These sensitivities are then analyzed temporally to generate skeletal models. The methodology is demonstrated by conducting skeletal reduction of constant density and temperature burning of carbon and oxygen relevant to Type Ia supernovae (SNe Ia). The 495-isotopes Torch model is chosen as the detailed reaction network. A map of maximum production of 56Ni in SNe Ia is produced for different temperatures, densities, and proton-to-neutron ratios. The f-OTD simulations and the sensitivity analyses are then performed with initial conditions from this map. A series of skeletal models are derived and their performances are assessed by comparison against currently existing skeletal models. Previous models have been constructed intuitively by assuming the dominance of α-chain reactions. The comparison of the newly generated skeletal models against previous models is based on the predicted energy release and 44Ti and 56Ni abundances by each model. The consequences of y

e
≠ 0.5 in the initial composition are also explored where y

e
is the electron fraction. The simulated results show that 56Ni production decreases by decreasing y

e
as expected, and that the 43Sc is a key isotope in proton and neutron channels toward 56Ni production. It is shown that an f-OTD skeletal model with 150 isotopes can accurately predict the 56Ni abundance in SNe Ia for y

≲ 0.5 initial conditions.
The Evolution of Stellar X-Ray Activity and Angular Momentum as Seen by eROSITA, TESS, and Gaia
Authors: Stassun Keivan G. , Kounkel Marina 
Published: May 2024

Abstract
We have assembled a sample of ∼8200 stars with spectral types F5V–M5V, all having directly measured X-ray luminosities from eROSITA and rotation periods from TESS and having empirically estimated ages via their membership in stellar clusters and groups identified in Gaia astrometry (ages 3–500 Myr). This is the largest such study sample yet assembled for the purpose of empirically constraining the evolution of rotationally driven stellar X-ray activity. We observe rotation–age–activity correlations that are qualitatively as expected: stars of a given spectral type spin down with age, and they become less X-ray active as they do so. We provide simple functional representations of these empirical relationships that predict X-ray luminosity from basic observables to within 0.3 dex. Interestingly, we find that the rotation–activity relationship is far simpler and more monotonic in form when expressed in terms of stellar angular momentum instead of rotation period. We discuss how this finding may relate to the long-established idea that rotation–activity relationships are mediated by stellar structure (e.g., convective turnover time, surface area). Finally, we provide an empirical relation that predicts stellar angular momentum from basic observables, without requiring a direct measurement of stellar rotation, to within 0.5 dex.
Cannibals in PARADISE: The Effect of Merging Interplanetary Shocks on Solar Energetic Particle Events
Authors: Niemela Antonio , Wijsen Nicolas , Aran Angels , Rodriguez Luciano , Magdalenic Jasmina , Poedts Stefaan 
Published: May 2024

Abstract
Gradual solar energetic particle (SEP) events are associated with shocks driven by coronal mass ejections (CMEs). The merging of two CMEs (so-called cannibalistic CMEs) and the interaction of their associated shocks has been linked to some of the most powerful solar storms ever recorded. Multiple studies have focused on the observational aspects of these SEP events, yet only a handful have focused on modeling similar CME–CME interactions in the heliosphere using advanced magnetohydrodynamic (MHD) models. This work presents, to our knowledge, the first modeling results of a fully time-dependent 3D simulation that captures both the interaction of two CMEs and its effect on the acceleration and transport of SEPs. This is achieved by using an MHD model for the solar wind and CME propagation together with an integrated SEP model. We perform different simulations and compare the behavior of the energetic protons in three different solar wind environments, where a combination of two SEP-accelerating CMEs are modeled. We find that particle acceleration is significantly affected by the presence of both CMEs in the simulation. Initially, less efficient acceleration results in lower-energy particles. However, as the CMEs converge and their shocks eventually merge, particle acceleration is significantly enhanced through multiple acceleration processes between CME-driven shocks, resulting in higher particle intensities and energy levels.
Suicide et carrière de l’homme disqualifié : une appréhension dynamique du « déficit d’intégration » durkheimien à partir de cas d’agriculteurs
Authors: Deffontaines Nicolas 
Published: May 2024

Les représentations communes associées aux suicides d’agriculteurs consacrent la figure de l’homme seul face aux difficultés économiques. Les agriculteurs seraient ainsi un cas d’étude privilégié pour penser le suicide égoïste, défini par Durkheim comme étant lié à un « déficit d’intégration ». Cette notion est cependant considérée comme difficilement opératoire parce qu’elle serait appréhendée de façon trop statique du fait de la pauvreté des données en matière de suicide. À partir d’une enquête qualitative construisant des trajectoires d’agriculteurs suicidés, cet article montre que le suicide égoïste peut être pensé comme le point ultime d’une carrière par laquelle l’individu se trouve disqualifié de l’ensemble des scènes sociales dans lesquelles il s’inscrivait.
Le sacrifice de l’ homo œconomicus

Published: May 2024

Le néolibéralisme a pris un virage sacrificiel suite à la crise de 2008 : alors qu’il promouvait le calcul d’intérêt, il prône désormais une forme éthico-religieuse de désintérêt, transformant les individus en soldats au service de l’économie. On peut lui opposer le droit humain à l’indépendance économique.
Médias sociaux et mobilisation citoyenne en période de crise : les leçons du mouvement « Makers » face à la pandémie de la Covid-19
Authors: Moussavou Jean 
Published: May 2024

Les crises voient souvent émerger différentes formes d’initiatives citoyennes. Grace aux médias sociaux, l’action collective des « Makers » pendant la pandémie de la Covid-19 a permis d’apporter les premières réponses en proposant un modèle de production d’équipements de protection individuelle (EPI). Une telle initiative montre comment l’innovation sociale s’est produite en dehors de l’Etat et du marché. L’article analyse comment ce mouvement a réussi à collaborer dans un contexte contraint par le confinement de la population. Il s’appuie sur une triangulation de données issues d’observations et d’entretiens semi-directifs en ligne, et d’une veille documentaire. Les résultats identifient les modalités d’émergence et d’auto-organisation de ce mouvement, et démontrent comment leur combinaison avec les médias sociaux a joué un rôle crucial dans la mobilisation des Makers. L’article offre un cas exemplaire de modèle alternatif d’organisation conçu entre l’Etat et le marché. Il fournit un cadre de réflexion aux processus de structuration et de coordination numériques en contexte de crise, qui profite à la fois à la théorie et à la pratique de la gestion de crise.
Efficacité des labels à but non lucratif et des notations commerciales pour orienter les flux financiers vers des fonds durables
Authors: Fox Mathilde , Nguyen Anh , Dumas Christel 
Published: May 2024

Avec la forte augmentation des fonds dits « durables », accompagnée de préoccupations concernant l’écoblanchiment et les critiques des agences de notation privées, les labels sont apparus comme une solution pour améliorer la transparence du marché et résoudre les problèmes d’agence. Leur adoption à grande échelle mérite une meilleure compréhension de leur rôle et de leur efficacité. C’est ainsi que cette recherche vise à analyser si les fonds communs de placement qui reçoivent un label à but non lucratif enregistrent des flux plus importants, et comment cela diffère pour les fonds qui ont déjà un rating de durabilité émise par une agence commerciale. Cette étude s’inscrit principalement dans le cadre de la théorie de l’agence. A l’aide de la méthode Difference-in-Difference, nous estimons l’effet de l’introduction du label Towards Sustainability sur les flux de fonds par rapport à une population de contrôle sans le label, construite avec à l’aide d’un propensity score matching. Les deux populations comptent chacune 18.585 observations mensuelles correspondant à environ 400 fonds. Nos résultats indiquent que l’obtention d’un label de durabilité à but non lucratif a un effet marginal positif sur les flux de fonds, mais uniquement pour les fonds qui n’ont pas de notation commerciale par ailleurs. Ces résultats confirment la préférence des investisseurs pour les fonds durables et montrent l’effet similaire des labels publics et des notations commerciales privées sur les problèmes d’agence, en améliorant la transparence. En accordant plus d’importance aux labels dans leur processus de décision d’investissement et la construction des fonds, les gestionnaires de fonds et les prestataires de services financiers ont la possibilité de rééquilibrer la répartition des rôles et du pouvoir des agences de rating commercial qui dominent sur les marchés financiers.
Une adhésion synonyme d’arc en ciel ? L’évolution de la situation des personnes LGBT en Croatie depuis 2013
Authors: Biesemans Romain 
Published: May 2024

La situation des personnes LGBT représente aujourd’hui un réel enjeu au sein de l’Union européenne. Cette situation est loin d’être homogène dans de nombreux domaines allant des droits aux attitudes sociales. L’objectif de cette recherche est de comprendre comment a évolué la situation des personnes LGBT en Croatie depuis l’adhésion à l’Union européenne en 2013. Nous étudions cette évolution en nous basant sur la théorie de la diffusion des normes et du processus d’européanisation en mobilisant les perceptions d’un type d’acteur ; les membres d’organisations LGBT croates. La situation des personnes LGBT en Croatie n’a pas évoluée significativement. Une des raisons principale réside dans la résistance de plusieurs acteurs à la diffusion des normes LGBT. Nous ne constatons pas de réels changements des attitudes sociales envers les personnes LGBT.
