Spin–Orbit Alignment of Early-type Astrometric Binaries and the Origin of Slow Rotators
Authors: Smith Chase L. , Moe Maxwell , Kratter Kaitlin M. 
Published: October 2024

Abstract
The spin–orbit alignment of binary stars traces their formation and accretion history. Previous studies of spin–orbit alignment have been limited to small samples, slowly rotating solar-type stars, and/or wide visual binaries that not surprisingly manifest random spin–orbit orientations. We analyze 917 Gaia astrometric binaries across periods P = 100–3000 days (a = 0.5–5 au) that have B8-F1 IV/V primaries (M
1 = 1.5–3 M
⊙) and measured projected rotational velocities v sin i. The primary stars in face-on orbits exhibit substantially smaller v sin i compared to those in edge-on orbits at the 6σ level, demonstrating significant spin–orbit alignment. The primaries in our astrometric binaries are rotating more slowly than their single-star or wide-binary counterparts and therefore comprise the slow-rotator population in the observed bimodal rotational velocity distribution of early-type stars. We discuss formation models of close binaries where some of the disk angular momentum is transferred to the orbit and/or secondary spin, quenching angular momentum flow to the primary spin. The primaries in astrometric binaries with small mass ratios q = M
2/M
1 < 0.3 possess even smaller v sin i, consistent with model predictions. Meanwhile, astrometric binaries with large eccentricities e > 0.4 do not display spin–orbit alignment or spin reduction. Using a Monte Carlo technique, we measure a spin–orbit alignment fraction of F
align = 75% ± 5% and an average spin reduction factor of 〈S
align〉 = 0.43 ± 0.04. We conclude that 75% of close A-type binaries likely experienced circumbinary disk accretion and probably formed via disk fragmentation and inward disk migration. The remaining 25%, mostly those with e > 0.4, likely formed via core fragmentation and orbital decay via dynamical friction.

Abstract
The CO(1–0) line has been carefully calibrated as a tracer of molecular gas mass. However, recent studies often favor higher J transitions of the CO molecule, which are brighter and accessible for redshift ranges where CO(1–0) is not. These lines are not perfect analogs for CO(1–0), owing to their more stringent excitation conditions, and must be calibrated for use as molecular gas tracers. Here, we introduce the Arizona Molecular ISM Survey with the SMT, a multi-CO line survey of z ∼ 0 galaxies conducted to calibrate the CO(2–1) and CO(3–2) lines. The final survey includes CO(2–1) spectra of 176 galaxies and CO(3–2) spectra for a subset of 45. We supplement these with archival CO(1–0) spectra from xCOLD GASS for all sources and additional CO(1–0) observations with the Kitt Peak 12 m Telescope. Targets were selected to be representative of the 109

⊙ galaxy population. Our project emphasized careful characterization of statistical and systematic uncertainties to enable studies of trends in CO line ratios. We show that optical and CO disk sizes are on average equal, for both the CO(1–0) and CO(2–1) line. We measure the distribution of CO line luminosity ratios, finding medians (16th–84th percentile) of 0.71 (0.51–0.96) for the CO(2–1)-to-CO(1–0) ratio, 0.39 (0.24–0.53) for the CO(3–2)-to-CO(1–0) ratio, and 0.53 (0.41–0.74) for the CO(3–2)-to-CO(2–1) ratio. A companion paper presents our study of CO(2–1)'s applicability as a molecular gas mass tracer and search for trends in the CO(2–1)-to-CO(1–0) ratio. Our catalog of CO line luminosities is publicly available.
Exploring the Magnetic and Thermal Evolution of a Coronal Jet

Published: October 2024

Abstract
Coronal jets are the captivating eruptions that are often found in the solar atmosphere and primarily formed due to magnetic reconnection. Despite their short-lived nature and lower energy compared to many other eruptive events, e.g., flares and coronal mass ejections, they play an important role in heating the corona and accelerating charged particles. However, their generation in the ambience of nonstandard flare regime is not fully understood, and warrant a deeper investigation, in terms of their onset, growth, eruption processes, and thermodynamic evolution. Toward this goal, this paper reports the results of a data-constrained three-dimensional magnetohydrodynamics (MHD) simulation of an eruptive jet; initialized with a non-force-free-field (NFFF) extrapolation and carried out in the spirit of implicit large eddy simulation (ILES). The simulation focuses on the magnetic and dynamical properties of the jet during its onset, and eruption phases, that occurred on 2015 February 5 in an active region NOAA AR12280, associated with a seemingly three-ribbon structure. In order to correlate its thermal evolution with computed energetics, the simulation results are compared with differential emission measurement analysis in the vicinity of the jet. Importantly, this combined approach provides an insight to the onset of reconnection in transients in terms of emission and the corresponding electric current profiles from MHD evolutions. The presented study captures the intricate topological dynamics, finds a close correspondence between the magnetic and thermal evolution in and around the jet location. Overall, it enriches the understanding of the thermal evolution due to MHD processes, which is one of the broader aspects to reveal the coronal heating problem.

Abstract
Time-domain studies of active galactic nuclei (AGNs) offer a powerful tool for understanding black hole accretion physics. Prior to the optical outburst on 2017 December 23, 1ES 1927+654 was classified as a “true” type 2 AGN, an unobscured source intrinsically devoid of broad-line emission in polarized spectra. Through our 3 yr monitoring campaign spanning X-ray to ultraviolet/optical wavelengths, we analyze the post-outburst evolution of the spectral energy distribution (SED) of 1ES 1927+654. Examination of the intrinsic SED and subsequent modeling using different models reveal that the post-outburst spectrum is best described by a combination of a disk, blackbody, and corona components. We detect systematic SED variability and identify four distinct stages in the evolution of these components. During the event the accretion rate is typically above the Eddington limit. The correlation between ultraviolet luminosity and optical to X-ray slope (α
OX) resembles that seen in previous studies of type 1 AGNs, yet exhibits two distinct branches with opposite slopes. The optical bolometric correction factor (κ
5100) is ∼10 times higher than typical AGNs, again displaying two distinct branches. Correlations among the corona optical depth, disk surface density, and α
OX provide compelling evidence of a disk–corona connection. The X-ray corona showcases systematic variation in the compactness-temperature plot. Between 200 and 650 days, the corona is “hotter when brighter,” whereas after 650 days, it becomes “cooler when brighter.” This bimodal behavior, in conjunction with the bifurcated branches of α
OX and κ
5100, offers strong evidence of a transition from a slim disk to a thin disk ∼650 days after the outburst.

Abstract
We measure the absolute proper motion of Andromeda III (And III) using Advanced Camera for Surveys/Wide Field Channel and WFPC2 exposures spanning an unprecedented 22 yr time baseline. The WFPC2 exposures have been processed using a deep-learning centering procedure recently developed as well as an improved astrometric calibration of the camera. The absolute proper motion zero point is given by 98 galaxies and 16 Gaia EDR3 stars. The resulting proper motion is (μ

Cascading Dark Energy
Authors: Rezazadeh Kazem , Ashoorioon Amjad , Grin Daniel 
Published: October 2024

Abstract
The standard cosmological model is in the midst of a stress test, thanks to the tension between supernova-based measurements of the Hubble constant H
0 and inferences of its values from cosmic microwave background (CMB) anisotropies. Numerous explanations for the present-day cosmic acceleration require the presence of a new fundamental scalar field, as do early dark energy solutions to the Hubble tension. This raises the possibility that multiple fields cooperatively contribute to the dark energy component in bursts throughout cosmic time due to distinct initial conditions and couplings. Here, this cascading dark energy scenario is illustrated through a realization that effectively reduces to a two-field model, with two epochs in which dark energy is cosmologically significant. The model is compared to measurements of the CMB and baryon acoustic oscillations, as well as both PANTHEON and SH0ES observations of Type Ia supernovae. Neglecting the linear perturbations, it is found that this scenario ameliorates the Hubble tension, improving over purely late-time models of dark energy and the agreement between the galaxy survey measurements of baryon acoustic oscillations.
Star Stream Velocity Distributions in Cold Dark Matter and Warm Dark Matter Galactic Halos
Authors: Carlberg Raymond G. , Jenkins Adrian , Frenk Carlos S. , Cooper Andrew P. 
Published: October 2024

Abstract
The dark matter subhalos orbiting in a galactic halo perturb the orbits of stars in thin stellar streams. Over time, the random velocities in the streams develop non-Gaussian wings. The rate of velocity increase is approximately a random walk at a rate proportional to the number of subhalos, primarily those in the mass range ≈106−7
M
⊙. The distribution of random velocities in long streams is measured in simulated Milky Way–like halos that develop in representative warm dark matter (WDM) and cold dark matter (CDM) cosmologies. The radial velocity distributions are well modeled as the sum of a Gaussian and an exponential. The resulting Markov Chain Monte Carlo fits find Gaussian cores of 1−2 km s−1 and exponential wings that increase from 3 km s−1 for 5.5 keV WDM, 4 km s−1 for 7 keV WDM, to 6 km s−1 for a CDM halo. The observational prospects to use stream measurements to constrain the nature of galactic dark matter are discussed.
The Large-scale Anisotropy and Flux (de)magnification of Ultrahigh-energy Cosmic Rays in the Galactic Magnetic Field
Authors: Bister Teresa , Farrar Glennys R. , Unger Michael 
Published: October 2024

Abstract
We calculate the arrival direction distribution of ultrahigh-energy cosmic rays (UHECRs) with a new suite of models of the Galactic magnetic field (GMF), assuming sources follow the large-scale structure of the Universe. Compared to previous GMF models, the amplitude of the dipole component of the UHECR arrival flux is significantly reduced. We find that the reduction is due to the accidentally coinciding position of the peak of the extragalactic UHECR flux and the boundary of strong flux demagnification due to the GMF toward the central region of the Galaxy. This serendipitous sensitivity of UHECR anisotropies to the GMF model will be a powerful probe of the source distribution as well as Galactic and extragalactic magnetic fields. Demagnification by the GMF also impacts the visibility of some popular source candidates.

Abstract
We introduce a new capability of the Neil Gehrels Swift Observatory, dubbed “continuous commanding,” that achieves 10 s latency response time on orbit to unscheduled target-of-opportunity requests received on the ground. We show that this will allow Swift to respond to premerger (early-warning) gravitational-wave (GW) detections, rapidly slewing the Burst Alert Telescope (BAT) across the sky to place the GW origin in the BAT field of view at or before merger time. This will dramatically increase the GW/gamma-ray burst (GRB) codetection rate and enable prompt arcminute localization of a neutron star merger. We simulate the full Swift response to a GW early-warning alert, including input sky maps produced at different early-warning times, a complete model of the Swift attitude control system, and a full accounting of the latency between the GW detectors and the spacecraft. 60 s of early warning can double the rate of a prompt GRB detection with arcminute localization, and 140 s guarantees observation anywhere on the unocculted sky, even with localization areas ≫1000 deg2. While 140 s is beyond current GW detector sensitivities, 30–70 s is achievable today. We show that the detection yield is now limited by the latency of LIGO/Virgo cyberinfrastructure and motivate a focus on its reduction. Continuous commanding has been integrated as a general capability of Swift, significantly increasing its versatility in response to the growing demands of time-domain astrophysics. We demonstrate this potential on an externally triggered fast radio burst (FRB), slewing 81° across the sky, and collecting X-ray and UV photons from the source position <150 s after the trigger was received from the Canadian Hydrogen Intensity Mapping Experiment, thereby setting the earliest and deepest such constraints on high-energy activity from nonrepeating FRBs. The Swift Team invites the community to consider and propose novel scientific applications of ultra-low-latency UV, X-ray, and gamma-ray observations.
Association of Nursing Home Residents' Demographic and Clinical Attributes and Nursing Home Characteristics With Self-Reported Ratings of Nursing Home Satisfaction

Published: October 2024

Purpose
The current study explored the association of nursing home (NH) residents' demographic and clinical attributes and NH characteristics with resident-reported satisfaction with NH communities.

Method
Pearson correlations and multiple linear regression were used to test the association of demographic and clinical attributes of residents and NH characteristics with resident-reported NH satisfaction with 197 NH residents from 28 NHs.

Results
Correlational analysis and regressions indicated an association among residents' demographic and clinical characteristics, NH characteristics, and self-reported NH satisfaction. Higher age, higher education, and race (minority status) were associated with greater resident-reported NH satisfaction. Greater NH staffing and for-profit ownership status were associated with less NH satisfaction. Greater resident depressive symptoms and dressing assistance were associated with lower resident-reported NH satisfaction.

Conclusion

Administrators and staff should look beyond NH characteristics and consider their residents' diverse personal characteristics to create an environment that promotes satisfaction and well-being. [

À partir des contributions rassemblées dans un dossier de la revue L’Espace géographique consacré aux politiques de l’échelle à l’Unesco, l’article propose une réflexion sur les usages que les acteurs, individuels ou institutionnels, peuvent faire des échelles en contexte patrimonial. Après avoir montré que mettre la focale sur les logiques d’échelles n’est pas abandonner la dimension du temps au profit de l’espace, l’auteur explique en quoi l’identification de la « bonne » échelle et le voyage entre les échelles fait partie de l’expertise patrimoniale. Discutant la notion de « scalability » (Tsing), il souligne pour finir la dimension politique que recouvre la rhétorique de la « bonne » échelle et les enjeux qu’elle implique en termes de représentation.

Published: October 2024

Abstract:
Accidental foreign body ingestion is commonly encountered in clinical practice, especially among children.Concern arises especially when the ingested foreign body is a sharp object due to the risk of perforation, mucosal injury, and impaction in the gut. Of inadvertently ingested foreign bodies, 10%–20% require endoscopic removal and <1% require open surgical intervention.Endoscopic management, though popular, still remains difficult due to the inaccessibility of certain points in the bowel. Here, we describe a 7-year-old male child who presented to us on March 31, 2024, with a history of accidental ingestion of an iron nail 2 days prior. Although colonoscopic retrieval was the first mode of management undertaken on the basis of impaction in the distal ileum, the same was not successful. Eventually, the child was placed on conservative management and the nail was passed per rectally spontaneously on defecation after 3 days of observation.

Published: October 2024

Abstract:
Gastrointestinal (GI) lymphoma, a form of extranodal variant of non-Hodgkin lymphoma (NHL), poses diagnostic challenges due to its nonspecific symptoms. Constituting 30%–40% of extranodal NHL cases, GI lymphomas frequently involve the stomach, small bowel, and ileocecal region. Diffuse large B-cell lymphoma (DLBCL) is noted as the predominant form of extranodal NHL. This report describes the diagnostic imaging and surgical intervention in an unusual occurrence of ileal DLBCL in a man aged 60. Initial ultrasound and subsequent comprehensive evaluation using contrast-enhanced computed tomography showed extensive ileal wall thickening, aneurysmal dilatation in the affected segment, a few enlarged pelvic lymph nodes, and heterogeneously enhancing deposits in the mesentery. The surgical intervention included right hemicolectomy and ileocolic anastomosis, revealing a 10-cm ileal mass and the mesenteric deposit. Histopathological analysis identified high-grade B-cell NHL, suggestive of DLBCL-germinal center subtype.
Understanding epigenetics in health and human diseases – An overview
Authors: Agarwal Avarna , Padhan Prasanta 
Published: October 2024

Abstract:
Epigenetics, the study of heritable changes in gene expression without alterations to the DNA sequence, is crucial for the complex interplay of genetic and environmental factors influencing human health. This overview traces the historical evolution of epigenetics, from early conceptualizations by Valentin Haecker and Conrad Waddington to modern insights such as epigenetic editing. Key mechanisms such as DNA methylation, histone modifications, and noncoding RNAs are explored, highlighting their roles in various diseases including cancer, cardiovascular conditions, neurodegenerative disorders, autoimmune diseases, and metabolic disorders. The influence of environmental factors on epigenetic plasticity underscores the importance of lifestyle choices in health outcomes. Promising therapeutic strategies using epigenetics pave the way for personalized medicine. This comprehensive review emphasizes the need for an integrative approach to health that considers the dynamic relationship between genetics, environment, and epigenetics.
Automated microbiological diagnosis of bloodstream infections

Published: October 2024

Abstract:
The term “bloodstream infection” (BSI) describes the existence of live microorganisms in the blood that have the potential to alter hemodynamic and clinical features, trigger an inflammatory response in the host, and have significant repercussions. Although viruses, fungi, bacteria, and protozoa can all cause bloodstream infections (BSIs), bacteria are the primary cause. When treating patients, it is critical to identify the bacteriological agent and its antibiotic susceptibility pattern as soon as possible. Blood samples from suspected BSI patients are run through automated culture systems to isolate bacteria. Two automated techniques for bacterial growth detection are BacT/Alert 3D and Bactec (BD), followed by Vitek-2’s AST and identification.
