Abstract
We present deep, wideband multifrequency radio observations (144 MHz−8 GHz) of the remarkable galaxy group NGC 741, which yield crucial insights into the interaction between the infalling head-tail radio galaxy (NGC 742) and the main group. Our new data provide an unprecedentedly detailed view of the NGC 741-742 system, including the shock cone, disrupted jets from NGC 742, the long (∼255 kpc) braided southern radio tail, and the eastern lobe-like structure (∼100 kpc), and reveal, for the first time, complex radio filaments throughout the tail and lobe, and a likely vortex ring behind the shock cone. The cone traces the bow shock caused by the supersonic (

) interaction between the head-tail radio galaxy NGC 742 and the intragroup medium (IGrM), while the ring may have been formed by the interaction between the NGC 742 shock and a previously existing lobe associated with NGC 741. This interaction plausibly compressed and reaccelerated the radio plasma. We estimate that shock-heating by NGC 742 has likely injected ∼2–5 × 1057 erg of thermal energy into the central 10 kpc cooling region of the IGrM, potentially affecting the cooling and feedback cycle of NGC 741. A comparison with Chandra X-ray images shows that some of the previously detected thermal filaments align with radio edges, suggesting compression of the IGrM as the relativistic plasma of the NGC 742 tail interacts with the surrounding medium. Our results highlight that multifrequency observations are key to disentangling the complex, intertwined origins of the variety of radio features seen in the galaxy group NGC 741, and the need for simulations to reproduce all the detected features.
Propagation of Gamma-Ray Burst Relativistic Jets in Active Galactic Nucleus Disks and Its Implication for Gamma-Ray Burst Detection

Published: November 2024

Abstract
The accretion disks of supermassive black holes (SMBHs) harboring in active galactic nuclei (AGN) are considered to be an ideal site for producing different types of gamma-ray bursts (GRBs). The detectability of these GRB phenomena hidden in AGN disks is highly dependent on the dynamical evolution of the GRB relativistic jets. By investigating the reverse- and forward-shock dynamics due to the interaction between the jets and AGN disk material, we find that the relativistic jets can successfully break out from the disks only for a sufficiently high luminosity and a long enough duration. In comparison, relatively normal GRB jets are inclined to be choked in the disks unless the GRBs occur near an SMBH with relatively low mass (e.g., ∼106
M
⊙). For the choked jets, unlike normal GRB prompt and afterglow emission, we can only expect to detect emission from the forward shock when the shock is very close to the edge of the disks, i.e., at the shock breakout emission and subsequent cooling of the shock.

Abstract
We present periodicity search analyses on the long-term γ-ray light curve of the BL Lacertae object 4FGL J2139.4−4235 observed by the Fermi Large Area Telescope, over a period of more than 15 yr, from 2008 August 4 to 2023 December 10. To determine the quasiperiodic oscillation (QPO) behavior of 4FGL J2139.4−4235 in the 0.3–300 GeV energy range, we used four methods, namely the Lomb–Scargle periodogram, the weighted wavelet z-transform, the phase dispersion minimization, and the autoregressive integrated moving average model. A Monte Carlo simulation technique is used to evaluate the significance level of the QPO signal. Significant levels above 3.5σ were detected in the γ-ray light curve at about 650 days QPO, which is presented throughout the observation period. Interestingly, there was some correlation between the three bands in the discrete correlation function method calculations, which may be an indication that the variability trends between the three bands are similar. We explore the possible physical models and show that a supermassive binary black hole system or a jet helical motion model seem to be reasonable explanations for the potential QPO behavior.

Published: November 2024

Abstract
We investigate the long-term persistence of the time series of energetic neutral atom (ENA) fluxes recorded by the Interstellar Boundary Explorer (IBEX). ENAs provide global information about the outer heliosphere and its interactions with the very local interstellar medium. To avoid the IBEX Ribbon, here, we focus our analysis solely on the polar regions N60°–N90° and S60°–S90°. Each year, IBEX takes two measurements of every pixel in the sky. We make use of the whole set of 14 yr of IBEX data and adhere to the correct time order for the construction of the flux time series. We examine in detail both the trend and the fluctuations of these time series. Using modern methods of time series analysis and persistence characterization, we show that the time series (i) trend is influenced by the solar cycle, (ii) persistence can be established independently of the presence of this trend, and (iii) statistical properties of the fluctuations differs between north and south, pointing to the existence of anisotropy and thus a north–south asymmetry.

Abstract
In this work, we update the catalog of OB stars based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope data release 7 and modify the OB stars’ selection criteria in spectral line indices’ space. The new catalog includes 37,778 spectra of 27,643 OB stars, of which 3827 OB stars are newly identified. The spectral subclasses of 27,643 OB stars are obtained using the automatic classification code MKCLASS. We find that the modified OB star selection criteria can better improve the completeness of late B-type stars by analyzing their spectral classification results given by MKCLASS. We also identify 3006 Be-type stars or candidates by examining the Balmer lines in their spectra and find that the frequency of our Be-type stars (10.9%) is consistent with previous results. The spatial distribution of OB stars indicates that they are mainly located in the Galactic disk. This new catalog of OB stars will provide valuable data for studying the structure and evolution of the Milky Way.

Abstract
JWST observations of the young Galactic supernova remnant Cassiopeia A revealed an unexpected structure seen as a green emission feature in colored composite MIRI F1130W and F1280W images—hence dubbed the Green Monster—that stretches across the central parts of the remnant in projection. Combining the kinematic information from NIRSpec and the MIRI Medium Resolution Spectrograph with the multiwavelength imaging from NIRCam and MIRI, we associate the Green Monster with circumstellar material (CSM) that was lost during an asymmetric mass-loss phase. MIRI images are dominated by dust emission, but their spectra show emission lines from Ne, H, and Fe with low radial velocities indicative of a CSM nature. An X-ray analysis of this feature in a companion paper supports its CSM nature and detects significant blueshifting, thereby placing the Green Monster on the nearside, in front of the Cas A supernova remnant. The most striking features of the Green Monster are dozens of almost perfectly circular 1″–3″ sized holes, most likely created by interaction between high-velocity supernova ejecta material and the CSM. Further investigation is needed to understand whether these holes were formed by small 8000–10,500 km s−1 N-rich ejecta knots that penetrated and advanced out ahead of the remnant’s 5000–6000 km s−1 outer blast wave or by narrow ejecta fingers that protrude into the forward-shocked CSM. The detection of the Green Monster provides further evidence of the highly asymmetric mass loss that Cas A’s progenitor star underwent prior to its explosion.
On the Early Thermal Processing of Planetesimals during and after the Giant Planet Instability

Abstract
Born as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets’ dynamical instability in the early stages of our solar system’s history. Here, we model the thermal evolution of planetesimals during and after the giant planet instability. We couple an adapted thermal evolution model to orbital trajectories provided by N-body simulations to account for the planetesimals’ orbital evolution, a parameter so far neglected by previous thermal evolution studies. Our simulations demonstrate intense thermal processing in all planetesimal populations, mainly concerning the hypervolatile ice content. Unlike previous predictions, we show that hypervolatile survival was possible in a significant number of planetesimals of the Kuiper Belt and the Oort Cloud. Planetesimals ejected into interstellar space proved to be the most processed, while planetesimals ending in the Oort Cloud were the least processed population. We show that processing differences between populations are a direct consequence of their orbital evolution patterns, and that they provide a natural explanation for the observed variability in the abundance ratios of CO on cometary populations and on the recent observations of long-distance CO-driven activity on inbound long-period comets.
How Meteor Showers Can Guide the Search for Long-period Comets

Published: November 2024

Abstract
With orbital periods longer than 200 yr, most long-period comets (LPCs) remain undiscovered until they are in-bound toward perihelion. The comets that pass close to Earth’s orbit are potentially hazardous objects. Those with orbital periods up to ∼4000 yr tend to have passed close to Earth’s orbit in a previous orbit and produced a meteoroid stream dense enough to be detected at Earth as a meteor shower. In anticipation of Rubin Observatory’s Legacy Survey of Space and Time (LSST), we investigate how these meteor showers can guide dedicated searches for their parent comets. Assuming search parameters informed by LSST, we calculated where the 17 known parent bodies of LPC meteor showers would have been discovered based on a cloud of synthetic comets generated from the shower properties as measured at Earth. We find that the synthetic comets predict the on-sky location of the parent comets at the time of their discovery. The parent comet’s location on average would have been 1.°51 ± 1.°19 from a line fit through the synthetic comet cloud. The difference between the heliocentric distance of the parent and mean heliocentric distance of synthetic comets on the line was 2.09 ± 1.89 au for comets with unknown absolute nuclear magnitudes and 0.96 ± 0.80 au for comets with known absolute nuclear magnitudes. We applied this method to the σ-Hydrids, the proposed meteor shower of comet Nishimura, and found that it successfully matched the pre-covery location of this comet 8 months prior to Nishimura’s discovery.
Transition to Professional Practice in the United States: Exploring the Experiences of Internationally Educated Nurses
Authors: Porter Marlene T. , Williams Kate , Gembol Leslie 
Published: November 2024

Background
Many countries facing workforce shortages rely on internationally educated nurses (IENs) to supplement the nursing workforce. The goal of this study is to investigate the experiences of IENs during the peak of their acculturation to their new environment.

Method
A descriptive qualitative approach was used with focus groups conducted 6 to 9 months after the IENs' start date. Purposive sampling was used to recruit participants at a large academic hospital. Focus groups were conducted in person, audiorecorded, and transcribed. Data were analyzed with reflexive thematic analysis.

Results
Twenty-seven subjects participated in the focus groups. Three key themes were identified to describe the experiences: (a) navigating the challenging journey, (b) unlearning-relearning nursing practice, and (c) adapting to the work environment.

Conclusion

This study was the first to examine IENs' experiences 6 to 9 months after arriving in the United States. Study findings show the importance of developing transition programs to support this population of nurses.

Acceptance of Digital Health Care Technology and the Role of Nursing Education
Authors: Han Jiyoung , Kim Meeyoung , Ryu Kum Hei , Shin Kwangsoo 
Published: November 2024

Background
As digital health care technology develops, the use of technology in the nursing field has become an essential part of nursing education. However, few studies have linked nurses' awareness of digital health care with nursing education. This study examines the direct effects and mediating effects of factors in technology acceptance on nurses' intention to accept digital health care technology.

Method
To empirically investigate these relationships, a survey was conducted among nurses in South Korea.

Results
This study emphasizes the importance of a multifaceted approach that considers personal, organizational, and innovation-related factors in understanding nurses' intentions toward acceptance of digital health care technologies.

Conclusion

The findings confirm that performance expectancy and facilitating conditions play crucial roles in nurses' acceptance of digital health care technologies. The mediating effects of performance expectancy and facilitating conditions on intentions to accept technologies suggest that these factors can also play vital indirect roles.

Published: November 2024

Background and Objective
This study aimed to investigate the rate of rhegmatogenous retinal detachment (RRD) in the fellow eye of patients after developing an RRD in one eye.

Patients and Methods
This is a retrospective cohort study of patients with a new RRD diagnosis in the American Academy of Ophthalmology IRIS Registry (Intelligent Research in Sight) from 2016 to 2020. The association between risk factors of RRD and fellow-eye RRD was evaluated using Cox regression.

Results

Among the 201,622 patients who developed a new RRD in at least one eye, 6,740 (3.34%) developed an RRD in the fellow eye at a mean time of 406.02 days (SD = 373.74) from the first eye diagnosis. Of those 6,740 eyes, 1,889 (28.03%) had lattice degeneration, 3,938 (58.43%) had PVD, 588 (8.72%) had cataract surgery, and 38 (0.56%) had complex cataract surgery. Adjusted regression modeling showed that male sex (HR 1.73, [95% confidence interval (CI) 1.64 to 1.83];
P
< 0.001), younger age at first eye RRD diagnosis (HR 1.02, [95% CI 1.01 to 1.02];
P
< 0.001), active smoking (HR 1.13, [95% CI 1.05 to 1.22];
P
= 0.002), and cataract surgery (HR 1.33, [95% CI 1.23 to 1.45];
P
< 0.001) were associated with increased risk of a fellow eye RRD. On the other hand, fellow eye PVD was associated with a lower risk of RRD (HR 0.80, [95% CI 0.76 to 0.84];
P
< 0.001).

Conclusion
Among patients with an RRD in one eye, male sex, younger age of first eye RRD diagnosis, active smoking, and cataract surgery were associated with a higher risk of developing a fellow eye RRD, whereas fellow eye PVD was associated with a lower risk of fellow eye RRD.

La Chine entendue par l’Occident
Authors: Jia Junyuan 
Published: November 2024

Dans le pavillon de la Chine lors de l’Exposition universelle de Paris en 1900, le public pouvait entendre des enregistrements sonores de seize dialectes chinois et de quarante morceaux d’opéra traditionnel chinois grâce à des cylindres d’enregistrements envoyés depuis la Chine. En parallèle, le docteur Léon Azoulay, membre de la Société d’anthropologie de Paris, a réalisé sur place des enregistrements de dialectes chinois et de chansons chinoises, grâce aux progrès des technologies d’enregistrement sonore. Dans cet article, l’auteure retrace l’histoire de cette technologie qui a enrichi la méthodologie des sciences humaines au xxe siècle. En s’appuyant sur une étude des enregistrements sonores chinois de l’Exposition universelle de 1900, l’auteure analyse la manière dont l’Occident percevait la Chine à travers l’acoustique à la fin du xixe siècle.
Sous la pression du temps
Authors: Weber Heike 
Published: November 2024

Le temps, dans ses évolutions comme dans ses échelles extrêmes, est devenu un défi sans précédent pour la société mondiale, rendant les connaissances historiques particulièrement pertinentes pour l’action. Comme les techniques sont vues comme la voie principale pour rendre les sociétés plus durables, le champ de l’histoire des techniques se voit placé au cœur des interrogations sur la portée et les conséquences de l’expertise historique. Dans cet essai, je soutiens que l’histoire des techniques peut contribuer à situer, encadrer et façonner les techniques contemporaines d’une manière sensible au temps. Je critique également un certain nombre de termes à la mode, comme celui de « disruption » ou de « tournant technique », qui dominent les discours malgré leur insensibilité au temps. L’histoire des techniques offre un vaste répertoire de passés potentiellement utilisables, alors que peu d’études de cas sont entrées dans le domaine des transition studies et de l’évaluation des choix techniques. C’est bien à nous, historiens et historiennes, qu’il revient d’investir ces domaines et de participer davantage à ces débats.
Intimate Partner Violence among Female Spouses of Men with Alcohol Dependence Syndrome: A Cross-sectional Study
Authors: Periyasamy Chinnadurai , Narayanan Gitanjali , Kandasamy Arun , Ezhumalai Sinu , Shanmugam Backiyaraj 
Published: November 2024

Background:
Worldwide, intimate partner violence (IPV) is a serious public health threat to women’s mental health. Female spouses of men with alcohol dependence often face various forms of abuse. IPV is widely prevalent among women who are married to men with alcohol dependence. However, the prevalence of IPV among female spouses of men seeking treatment for their alcohol dependence is unclear.

Methods:
A cross-sectional study design was used. A total of 110 female spouses of men with alcohol dependence syndrome were selected using purposive sampling from the Centre for Addiction Medicine, National Institute of Mental Health and Neurosciences, Bengaluru, India. A Composite Abuse Scale-Short Form was used to assess the prevalence and pattern of IPV. The interview method was used to collect the data. Independent sample ‛t՚ test and logistic regression analysis were used to analyze the data.

Results:
The mean age of participants is 33 years (±6.34). Most (85.5%) participants experienced different forms of IPV. Prevalence for physical violence was 82.7%, followed by psychological violence (76.4%). Nearly, one-third of the participants (30%) reported sexual violence, and similarly, close to one-third (30%) experienced all forms of IPV. Men who were involved in gambling had significantly higher IPV toward their wives than nongamblers. The employment status among female spouses and urban domicile strongly predicted IPV.

Conclusion:
The prevalence of IPV among female spouses of men with alcohol dependence is 85.5%. Evidence-based psychiatric social work interventions need to be provided to address IPV among wives of persons with alcohol dependence in routine clinical practice at de-addiction centers.
