Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects
Authors: Chachan Yayaati , Lee Eve J. 
Published: December 2024

Abstract
Small planets (≲1 M
⊕) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and unveil the small planet population at 1–10 au. Instrumental sensitivity to such planets is low, and the number of objects we will discover is strongly dependent on the underlying planet mass function. In this work, we provide a physically motivated planet mass function by combining the efficiency of planet formation by pebble accretion with the observed disk mass function. Because the disk mass function for M dwarfs (0.4–0.6 M
⊙) is bottom heavy, the initial planet mass function is also expected to be bottom heavy, skewing toward Ganymede and Mars mass objects, more so for heavier initial planetary seeds. We follow the subsequent dynamical evolution of planetary systems over ∼100 Myr varying the initial eccentricity and orbital spacing. For initial planet separations of ≥3 local disk scale heights, we find that Ganymede and Mars mass planets do not grow significantly by mergers. However, Earth-like planets undergo vigorous merging and turn into super-Earths, potentially creating a gap in the planet mass function at ∼1 M
⊕. Our results demonstrate that the slope of the mass function and the location of the potential gap in the mass function can probe the initial architecture of multiplanet systems. We close by discussing implications on the expected difference between bound and free-floating planet mass functions.
On the Influence of the Solar Wind on the Propagation of Earth-impacting Coronal Mass Ejections

Published: December 2024

Abstract
Coronal mass ejections (CMEs) are subject to changes in their direction of propagation, tilt, and other properties as they interact with the variable solar wind. We investigated the heliospheric propagation of 15 Earth-impacting CMEs observed during 2010 April to 2018 August in the field of view (FOV) of the Heliospheric Imager (HI) on board the STEREO. About half of the 15 events followed self-similar expansion up to 40 R
⊙. The remaining events showed deflection either in latitude, longitude, or a tilt change. Only 2 events showed significant rotation in the HI1 FOV. We also use toroidal and cylindrical flux rope fitting on the in situ observations of interplanetary magnetic field and solar wind parameters to estimate the tilt at L1 for these 2 events. Although the sample size is small, this study suggests that CME rotation is not very common in the heliosphere. We attributed the observed deflections and rotations of CMEs to a combination of factors, including their interaction with the ambient solar wind and the influence of the ambient magnetic field. These findings contribute to our understanding of the complex dynamics involved in CME propagation and highlight the need for comprehensive modeling and observational studies to improve space weather prediction. In particular, HI observations help us to connect observations near the Sun and near the Earth, improving our understanding of how CMEs move through the heliosphere.
PMN J1310–5552: A Gamma-Ray-emitting Blazar Candidate Harboring a Cosmic Monster
Authors: Paliya Vaidehi S. 
Published: December 2024

Abstract
Relativistic jets manifest some of the most intriguing activities in the nuclear regions of active galaxies. Identifying the most powerful relativistic jets permits us to probe the most luminous accretion systems and, in turn, the most massive black holes. This paper reports the identification of one such object, PMN J1310−5552 (z = 1.56), a blazar candidate of uncertain type detected with the Fermi Large Area Telescope (LAT) and Swift Burst Alert Telescope. The detection of broad emission lines in its optical spectra taken with the X-Shooter and Goodman spectrographs classifies it to be a flat-spectrum radio quasar. The analysis of the Goodman optical spectrum has revealed PMN J1310−5552 harbors a massive black hole (log scale M
BH = 9.90 ± 0.07, in M
⊙) and luminous accretion disk (log scale L
disk = 46.86 ± 0.03, in erg s−1). The fitting of the observed big blue bump with the standard accretion disk model resulted in the log scale M

(in erg s−1), respectively. These parameters suggest PMN J1310−5552 hosts one of the most massive black holes and the most luminous accretion disks among the blazar population. The physical properties of this enigmatic blazar were studied by modeling the broadband spectral energy distribution considering the data from NuSTAR, Swift, Fermi-LAT, and archival observations. Overall, PMN J1310−5552 is a powerful “MeV” blazar with physical parameters similar to other members of this unique class of blazars. These results provide glimpses of monsters lurking among the unknown high-energy emitters and demonstrate the importance of ongoing wide-field sky surveys to discover them.

Abstract
We report the discovery of three faint and ultrafaint dwarf galaxies—Sculptor A, Sculptor B, and Sculptor C—in the direction of NGC 300 (D = 2.0 Mpc), a Large Magellanic Cloud–mass galaxy. Deep ground-based imaging with Gemini/GMOS resolves all three dwarf galaxies into stars, each displaying a red giant branch indicative of an old, metal-poor stellar population. No young stars or H i gas are apparent, and the lack of a GALEX UV detection suggests that all three systems are quenched. Sculptor C (D = 2.04

Published: December 2024

Birds are one of the most diverse groups among terrestrial vertebrates. They evolved from theropod dinosaurs, are closely related to the sauropsid group and separated from crocodiles about 240 million years ago. According to the IUCN, 12% of bird populations are threatened with potential extinction. Classical cytogenetics remains a powerful tool for comparing bird genomes and plays a crucial role in the preservation populations of endangered species. It thus makes it possible to detect chromosomal abnormalities responsible for early embryonic mortalities. Thus, in this work, we have provided new information on part of the evolutionary history by analysing high-resolution GTG-banded chromosomes to detect inter- and intrachromosomal rearrangements in six species. Indeed, the first eight autosomal pairs and the sex chromosomes of the domestic fowl Gallus gallus domesticus Linnaeus, 1758 were compared with five species, four of which represent the order Galliformes (Common and Japanese quail, Gambras and Chukar partridge) and one Otidiformes species (Houbara bustard).
Our findings suggest a high degree of conservation of the analysed ancestral chromosomes of the four Galliformes species, with the exception of (double, terminal, para and pericentric) inversions, deletion and the formation of neocentromeres (1, 2, 4, 7, 8, Z and W chromosomes). In addition to the detected rearrangements, reorganisation of the Houbara bustard chromosomes mainly included fusions and fissions involving both macro- and microchromosomes (especially on 2, 4 and Z chromosomes). We also found interchromosomal rearrangements involving shared microchromosomes (10, 11, 13, 14 and 19) between the two analysed avian orders. These rearrangements confirm that the structure of avian karyotypes will be more conserved at the interchromosomal but not at intrachromosomal scale.
The appearance ofa small number of inter- and intrachromosomal rearrangements that occurred during evolution suggests a high degree of conservatism of genome organisation in these six species studied. A summary diagram of the rearrangements detected in this study is proposed to explain the chronology of the appearance of various evolutionary events starting from the ancestral karyotype.
Catholiques et politique aux États-Unis
Authors: Chelini-Pont Blandine 
Published: December 2024

Une frange catholique radicale rejoint une mouvance fondamentaliste de l’évangélisme dans la revendication d’une identité nationale ethno-religieuse aux États-Unis. L’émergence de courants ultraconservateurs ne doit pas dissimuler la grande pluralité politique des catholiques américains lors des dernières élections. Pour la comprendre, il faut revenir à l’histoire, en particulier la rupture des années 1970 et la sensibilité croissante pour les questions « sociétales » qui provoque une forte polarisation.
Uno, nessuno, tre : assenza e presenza dell’autore in Sei personaggi in cerca d’autore
Authors: Bossche Bart Van den 
Published: December 2024

Cet article est consacré à la figure de l’auteur dans Six personnages en quête d’auteur de Pirandello, et en particulier à ce que les commentaires des acteurs, des personnages et du metteur en scène révèlent de la fonction d’auteur au sens large. Les rôles et les valeurs attribués à la fonction d’auteur concernent trois fonctions principales : l’auteur en tant que "marque", le rôle de l’auteur dans le processus créatif, et l’autorité qu’un auteur peut ou ne peut pas exercer sur son œuvre. Les trois fonctions d’auteur discutées renvoient à des questions qui s’inscrivent dans des préoccupations et obsessions largement diffusées dans la modernité littéraire.
Il tesoro dei poveri de Gabriele D’Annunzio : de Alī Ad-Dūʿāǧī à Catherine Tissier, le parcours atypique d’une traduction
Authors: Tbini Jihane 
Published: December 2024

Cet article confronte deux traductions de la nouvelle Il tesoro dei poveri de G. D’Annunzio (1887) : la traduction arabe de l’écrivain tunisien ʿAlī Ad-Dūʿāǧī, publiée en 1935 et la traduction française de Catherine Tissier (2008). Pour la version en français, le texte-source de référence est celui en arabe de Ad-Dūʿāǧī. L’analyse souligne les écarts entre les trois textes et montre que les choix de traduction vont dans le sens d’un détournement générique et d’un transfert culturel. La version française de Tissier s’apparente à une rétrotraduction de la matrice italienne, révélant ainsi le parcours atypique d’une traduction.

Published: December 2024

Abstract

Context:
The importance of analyzing head impact exposure among football players is well established, yet few studies have explored the differences across position groups in high school athletes. Better understanding of these differences may provide optimized intervention strategies for coaches and healthcare providers.

Objective:
To quantify the difference of head impacts per exposure (Imp/E) and impact burden high school football player position groups.

Design:
Prospective observational.

Setting:
High school athletic fields during Fall sports seasons.

Patients and Participants:
200 football players from three high school varsity teams including 69 offensive/defensive linemen, 51 linebackers/running backs/tight ends and 80 cornerbacks/safeties/wide receivers (16.1±0.9yrs, 177.9±7.8cm, 86.4±22.7) categorized as linemen, backers, and skills players respectively.

Main Outcome Measures:
Imp/E across positions, teams, session type, and seasons. Cumulative head impact burden per location (front, top, right, left, back) across position groups.

Results:
Significant differences in Imp/E were found between position groups (P&lt;0.001), where the backers group, (3.77[95% CI: 3.146, 4.395]) experienced higher total Imp/E compared to linemen (1.47[ 95% CI: 0.983, 1.96]) and skill players (1.56[95% CI: 1.11, 2.01]). Total accumulated burden of head impacts was significant (F(2,194) = 4.938, P&lt;0.008), with backers (4622.85g’s [95% CI: 3077.43, 6168.27]) significantly (P=0.011) higher than linemen (2657.70g’s [95% CI: 2045.61, 3269.19 ]) and skill players (2875.7g’s [95% CI: 2216.38, 3535.01]) (P=0.022). Front location impact burden (F(2, 194) = 7.784, P&lt;0.001) revealed backers (1606.24g’s [95% CI: 977.89, 2234.58]) also significantly (P=0.008) higher than both linemen (768.24g’s [95% CI: 433.84, 1102.64]) and skill players (567.75g’s [95% CI: 360.71, 774.78]) (P&lt;0.001).

Conclusion:
Linebackers, tight ends, and running backs experienced more Imp/E and higher cumulative burden than other positions, which highlights the potential influence of specific positional requirements during football participation. Coaches and healthcare providers should be aware that a position’s role during play may directly relate to changes in head impact risk.
Supervisor Authority and its Impacts on Equity, Diversity, and Inclusion in Athletic Training
Authors: TO Jean , JY Young , Nye Edler , EA Nye , LE Eberman 
Published: December 2024

ABSTRACT

Context
The demographic landscape of the United States is changing daily and the demand for representation in today’s workforce is both a moral and practical imperative for creating workplaces diverse in thought, expression, and people.

Objective
The purpose of this study was to investigate workplace culture and the direct and indirect influence of supervisors on inclusion of minoritized communities, including those who have experienced marginalization for race, ethnicity, religion, national origin, age, marital status, ability, sexual orientation, sex, gender, gender identity and expression, socioeconomic status, spirituality, political affiliation, literacy, or the intersectionality of multiple identities.

Design
Consensual qualitative research study

Setting
Semi-structured interview

Patients or Other Participants
Eighteen participants were recruited through direct contact via their public domain email addresses that are located on college/university websites.

Data Collection and Analysis
Demographic data was collected through a web-based recruitment survey which was also used to schedule a semi-structured interview. We used the multi-phased CQR tradition to identify domains and categories representative of the data.

Results
Three domains emerged. The environment domain spoke to the culture each supervisor created through relationship building and intention; intention was further characterized as active or passive behaviors whereby almost all participants described both. Only one-third of participants referenced DEIA policies and procedures within their organization. The resources domain represented the existence and awareness of organizational DEIA resources, or lack thereof. The perceptions domain characterized the beliefs of the supervisors relative to DEIA.

Conclusions
Structural efforts must include the creation and implementation of policies and procedures for employee inclusion, not just patient inclusion. The awareness and use of organizational resources is an important component to support supervisor efforts and should be leveraged from within the unit.
Association between Pregnancy and Musculoskeletal Conditions in Active-Duty Military Service Members
Authors: Roach Megan H. , Nelson D. Alan , Koreerat Christina M. , Foglia Lisa M. , Mauntel Timothy C. 
Published: December 2024

Abstract

Context:
Non-combat musculoskeletal conditions are endemic among service members and disproportionately affect females. Pregnancy and childbirth contribute to lower physical fitness assessment scores and higher body mass index, both risk factors for musculoskeletal conditions, for up to one-year post-pregnancy. However, there is a paucity of information regarding the impact of pregnancy on musculoskeletal conditions.

Objective:
To explore the association between the post-pregnancy period and incident musculoskeletal conditions (MSK).

Design:
Retrospective, longitudinal cohort study.

Setting:
Medical and administrative data from the Medical Assessment and Readiness System.

Other Participants:
Female military service members with and without a pregnancy.

Main Outcome Measure(s):
Months since pregnancy end, health history, and demographic and military service data were abstracted for each subject. Subsequent MSKs were identified with relevant ICD-10 codes. A multivariable logistic regression model assessed the association between the time since pregnancy end and MSK incidence.

Results:
A total of 298,607 female service members were identified, of which 19,980 had a pregnancy. A larger percentage of post-pregnancy service members (65.8%) had a MSK diagnosis as compared to the non-pregnant cohort (60.3%). Adjusting for covariates, the model suggests a temporal influence on post-pregnancy MSK incidence, such that service members 3- to 4-months and 5- to 6-months post-pregnancy were more likely to be diagnosed with a MSK as compared to the non-pregnant cohort. However, service members &lt;2 months post-pregnancy were less likely to be diagnosed with an MSK, and the odds of an MSK beyond 6-months decreased out to 24-months post-pregnancy.

Conclusions:
Pregnancy may increase a service member’s odds of sustaining an MSK 3- to 6- months post-pregnancy. Understanding the relationships between pregnancy and MSK risks may lead to changes in postpartum return-to-duty/activity policies, better enabling service members to care for themselves and their families.
Return-to-Learn for the K-12 Student: a Mixed-Methods Systematic Review
Authors: Dieball Molly , Grant Sophie , Kingma Jackie , Kawata Keisuke , Bevilacqua Zachary 
Published: December 2024

ABSTRACT

Objective:
Our aim was to perform a systematic review of Return-to-Learn literature with the intent of determining what items are necessary to form a comprehensive Return-to-Learn policy.

Data Sources:
We searched CINAHL, Embase, PubMed, Scopus, Google Scholar, and WorldWideScience.org using 25 search terms including return to learn, adolescents, concussion management, concussion AND children, concussion AND department of education, concussion AND secondary schools, concussion AND middle school, concussion AND primary school, concussion AND policy AND procedures, concussion AND 504 plans.

Study Selection:
Eligible studies were (i) published between 2009 and 2022; (ii) originally published in English in a peer-reviewed journal; (iii) have a full text available; (iv) discuss the K-12 population; (v) contain one of the following terms in the body of the document: Return to Learn, RTL, Return to School, Return to Classroom, or Return to Academics; (vi) identify RTL as a primary aim of the document.

Data Extraction:
The Qualitative Assessment and Review Instrument and JBI Meta-Analysis of Statistics Assessment and Review Instrument tools were used to extract data from eligible studies. Extraction occurred independently by two researchers.

Data Synthesis
Review yielded 32,766 articles, with 58 meeting inclusion criteria. Two qualitative themes and five subthemes aggregated with six quantitative narratives to produce five converged findings: 1) members and point person, 2) overcoming barriers to communication, 3) increasing concussion knowledge and training in the school system, 4) recommendations in the classroom, and 5) tackling the invisible injury.

Conclusions:
Less than one-third of included articles reported data from younger (K-8) cohorts, therefore, the converged findings represent significant facets of high school Return-to-Learn that stakeholders should embed into novel and revised state concussion legislation. Subsequent efforts should seek to appraise current state Return-to-Learn laws for existing use of evidence-based practice and begin accumulating data specific to younger students and school professionals that monitor and teach these individuals such that commensurate policy recommendations can then be made.
Anxiety-Related Concussion Perceptions of Parents of Youth Athletes

Published: December 2024

Abstract

Context:
Parents are key decisionmakers for 1 the health and wellness of their children. Despite the benefits of engaging in physical activity, parental concerns about concussion may create hesitancy towards sport participation. The magnitude of concussion-related anxiety perceptions and factors that influence these beliefs in parents of youth athletes are largely unknown.

Objective:
To determine the prevalence of concussion-related anxiety perceptions in parents of youth athletes and establish the associations among concussion-related anxiety and demographic variables (i.e., parent sex, parent concussion history, child concussion history, parent concussion education).

Design:
Cross-sectional paper survey.

Setting:
Youth sports.

Patients or Other Participants:
452 parents (60% female; mean age = 40.4±13.0 years) of youth athletes (8-14 years old) who participated in soccer, ice hockey, lacrosse, and football (i.e., higher concussion risk sports) in Pennsylvania and Michigan.

Main outcomes Measures:
Survey items were adapted from the Perceptions of Concussion Inventory for Athletes (PCI-A) to pertain to perceptions about their child. Parents also completed a demographic survey regarding concussion-related topics.

Results:
Overall, 73.2% of parents found the possibility of their child sustaining a concussion to be upsetting, 61.5% were fearful of their child sustaining a concussion, and 45.1% reported that the thought of their child having a concussion makes them feel anxious. Only 4.6% of parents suggested that concussions do not worry them. The lack of a personal concussion history and being female were associated with greater concussion-related anxiety in parents.

Conclusions:
This study provides evidence that parents of youth athletes have anxiety about their child sustaining a concussion, while also contributing to the understanding of what factors are related to such anxiety (i.e., female parent; no parent history of concussion). Negative parental concussion beliefs may contribute to the reduction in contact sport participation and should be directly addressed in concussion education specific to youth sport participation.
