Abstract
Warm Jupiters lay out an excellent laboratory for testing models of planet formation and migration. Their separation from the host star makes tidal reprocessing of their orbits ineffective, which preserves the orbital architectures that result from the planet-forming process. Among the measurable properties, the orbital inclination with respect to the stellar rotational axis, stands out as a crucial diagnostic for understanding the migration mechanisms behind the origin of close-in planets. Observational limitations have made the procurement of spin–orbit measurements heavily biased toward hot Jupiter systems. In recent years, however, high-precision spectroscopy has begun to provide obliquity measurements for planets well into the warm Jupiter regime. In this study, we present Rossiter–McLaughlin (RM) measurements of the projected obliquity angle for the warm Jupiter TOI-677 b using ESPRESSO at the VLT. TOI-677 b exhibits an extreme degree of alignment (λ = 0.3 ± 1.3 deg), which is particularly puzzling given its significant eccentricity (e ≈ 0.45). TOI-677 b thus joins a growing class of close-in giants that exhibit large eccentricities and low spin–orbit angles, which is a configuration not predicted by existing models. We also present the detection of a candidate outer brown dwarf companion on an eccentric, wide orbit (e ≈ 0.4 and P ≈ 13 yr). Using simple estimates, we show that this companion is unlikely to be the cause of the unusual orbit of TOI-677 b. Therefore, it is essential that future efforts prioritize the acquisition of RM measurements for warm Jupiters.
SPYGLASS. IV. New Stellar Survey of Recent Star Formation within 1 kpc
Authors: Kerr Ronan , Kraus Adam L. , Rizzuto Aaron C. 
Published: August 2023

Abstract
Young stellar populations provide a powerful record that traces millions of years of star formation history in the solar neighborhood. Using a revised form of the SPYGLASS young star identification methodology, we produce an expanded census of nearby young stars (age < 50 Myr). We then use the HDBSCAN clustering algorithm to produce a new SPYGLASS Catalog of Young Associations, which reveals 116 young associations within 1 kpc. More than 25% of these groups are largely new discoveries, as 20 are substantively different from any previous definition, and 10 have no equivalent in the literature. The new associations reveal a yet undiscovered demographic of small associations with little connection to larger structures. Some of the groups we identify are especially unique for their high transverse velocities, which can differ from the solar velocity by 30–50 km s−1, and for their positions, which can reach up to 300 pc above the galactic plane. These features may suggest a unique origin, matching existing evidence of infalling gas parcels interacting with the disk interstellar medium. Our clustering also suggests links between often-separated populations, hinting to direct structural connections between Orion Complex and Perseus OB2, and between the subregions of Vela. The ∼30 Myr old Cepheus-Hercules association is another emerging large-scale structure, with a size and population comparable to Sco-Cen. Cep-Her and other similarly aged structures are also found clustered along extended structures perpendicular to known spiral arm structure, suggesting that arm-aligned star formation patterns have only recently become dominant in the solar neighborhood.
The Galaxy–Halo Connection of DESI Luminous Red Galaxies with Subhalo Abundance Matching

Published: August 2023

Abstract
We use subhalo abundance and age distribution matching to create magnitude-limited mock galaxy catalogs at z ∼ 0.43, 0.52, and 0.63 with z-band and 3.4 μm W1-band absolute magnitudes and r − z and r − W1 colors. From these magnitude-limited mocks, we select mock luminous red galaxy (LRG) samples according to the (r − z)-based (optical) and (r − W1)-based (infrared) selection criteria for the LRG sample of the Dark Energy Spectroscopic Instrument (DESI) survey. Our models reproduce the number densities, luminosity functions, color distributions, and projected clustering of the DESI Legacy Surveys that are the basis for DESI LRG target selection. We predict the halo occupation statistics of both optical and IR DESI LRGs at fixed cosmology and assess the differences between the two LRG samples. We find that IR-based SHAM modeling represents the differences between the optical and IR LRG populations better than using the z band and that age distribution matching overpredicts the clustering of LRGs, implying that galaxy color is uncorrelated with halo age in the LRG regime. Both the optical and IR DESI LRG target selections exclude some of the most luminous galaxies that would appear to be LRGs based on their position on the red sequence in optical color–magnitude space. Both selections also yield populations with a nontrivial LRG–halo connection that does not reach unity for the most massive halos. We find that the IR selection achieves greater completeness (≳90%) than the optical selection across all redshift bins studied.
Simulation of Head-on Collisions between Filamentary Molecular Clouds Threaded by a Lateral Magnetic Field and Subsequent Evolution

Published: August 2023

Abstract
Filamentary molecular clouds are regarded as the place where newborn stars form. In particular, a hub region, a place where it appears as if several filaments are colliding, often indicates active star formation. To understand the star formation in filament structures, we investigate the collisions between two filaments using two-dimensional magnetohydrodynamical simulations. As a model of filaments, we assume that the filaments are in magnetohydrostatic equilibrium under a global magnetic field perpendicular to the filament axis. We set two identical filaments with an infinite length and make them collide with a zero-impact parameter (head-on). When the two filaments collide while sharing the same magnetic flux, we found two types of evolution after a merged filament is formed: runaway radial collapse and stable oscillation with a finite amplitude. The condition for the radial collapse is independent of the collision velocity and is given by the total line mass of the two filaments exceeding the magnetically critical line mass for which no magnetohydrostatic solution exists. The radial collapse proceeds in a self-similar manner, resulting in a unique distribution irrespective of the various initial line masses of the filament, as the collapse progresses. When the total line mass is less massive than the magnetically critical line mass, the merged filament oscillates, and the density distribution is well-fitted by a magnetohydrostatic equilibrium solution. The condition necessary for the radial collapse is also applicable to the collision whose direction is perpendicular to the global magnetic field.

The Herpetology Collection of the Natural History Museum Gustavo Orcés V. at Escuela Politécnica Nacional (MEPN-H) in Quito maintains more than sixteen thousand curated specimens and it comprises Ecuador ́s second largest collection of herps.
The Collection contains 193 type specimens: 14 holotypes, 34 paratopotypes and 145 paratypes, which correspond to 10 families, 17 genera and 32 species. The collection of type specimens is particularly important in the genera Atelopus and Pristimantis in amphibians and the genera Atractus and Enyaloides in reptiles. An assessment of the geographic distribution showed that collection sites of type specimens are clustered towards the south of Ecuador in the provinces of Zamora Chinchipe, Morona Santiago and Pastaza in the Amazon Region; and in the provinces of Carchi and Azuay in the Andes. The collection of type specimens dates from 1955 to 2013, comprising an invaluable source of historical biodiversity data.
Reaching Further with Earth Science Data
Authors: Walcott Rachel , Lehnert Kerstin 
Published: August 2023

Earth Sciences cover a broad spectrum of research fields such as petrology, sedimentology, structural geology, seismology, and geomorphology, to name a few, which aim to understand interrelated processes on the surface and in the interior of our planet. Many of the research questions studied in the Earth sciences, such as, understanding past climates, the human impact on the Critical Zone*1, or the co-evolution of the geo- and biosphere, require interdisciplinary approaches, employing methodologies and integrating observations from diverse subdisciplines such as geochemistry, mineralogy, geophysics, and paleontology, but also increasingly from other disciplines, specifically biology and genomics. The use of data and samples in multi- and interdisciplinary research is substantially facilitated by consistent metadata including schemas and vocabularies, data formats, and data exchange protocols.
The association of Biodiversity Information Standards (TDWG) with the Earth Science part of the Natural Sciences has, until recently, been largely limited to palaeontology, primarily due to its close affinity with biology. Standards have been developed that support the taxonomy of fossils and include terms for "deep time" intervals (chrono- and bio-stratigraphy) and "paleo-surface environment" (sedimentology). Other important and highly relevant fields such as mineralogy, geochemistry, meteoritics, and soil sciences have not been included or coordinated with so far. Although some progress is being made with the ongoing development of the Mineral Extension for Darwin Core and the inclusion of some geological terms in Latimer Core (Woodburn et al. 2022), more effort should be made to link and align with existing and emerging data standards in these Earth Science communities. These Earth Science communities are very active, building their own domain-specific FAIR (Findable, Accessible, Interoperable, Reusable) data standards and infrastructures with data systems such as EarthChem, the Astromaterials Data System, Mindat, and WoSIS.
We will introduce the users, data systems, and community standards and best practices, including metadata, vocabularies, and persistent identifiers for data and samples being used and developed in the subdisciplines of the Earth Sciences mentioned above. We advocate for collaboration and coordination with these fields to make TDWG more inclusive, expand accessible resources, and provide an opportunity for TDWG to link to these other communities. Broader networking within an interdisciplinary research framework has the potential to address more fundamental and over-arching issues of both scientific and public relevance.

Objective:To analyze age-related changes in the choroid in healthy eyes using swept-source optical coherence tomography angiography (SS-OCTA).Patients and Methods:This was a cross-sectional, prospective, observational study enrolling 222 eyes of 116 healthy participants. SS-OCTA images were captured using the PLEX Elite 9000 (Carl Zeiss Meditec) with a 6 x 6 mm pattern centered on the fovea. Subfoveal choroidal thickness (CT) and choroidal volume (CV) were generated automatically through manufacturer tools available in the Advanced Retinal Imaging (ARI) hub network. Choroidal vascularity index (CVI) and choriocapillaris flow deficits (CCFD) were computed using ImageJ.Results:CV was found to be significantly higher in women than men. Overall, there was a significant positive correlation between CVI and CCFD, and a significant negative correlation between CT and CV with age. The relationship, however, was more complex, as a decade-wise analysis showed that CT and CV increased until the second decade, followed by a decrease until the sixth decade, and then an increase again in the seventh and eighth decades. CVI was highest in the seventh decade. In contrast, CCFD increased consistently with age and in all the Early Treatment of Diabetic Retinopathy Study (ETDRS) rings.Conclusion:The choroidal blood flow and its thickness reduces as the age advances. While the choroidal flow deficits show a consistent increase with age and the distance from the foveal center, the relationship of other parameters with age is more complex. Having a normative database from healthy subjects is imperative for understanding the changes taking place in diseased states. Choroidal parameters can show significant variations with age. These differences are not uniform or consistent with age, highlighting the importance of a normative reference database to assess the significance of choroidal alterations associated with disease.[Ophthalmic Surg Lasers Imaging Retina2023;54:526–534.]
THERAPY-RELATED MYELOID NEOPLASMS: CONSIDERATIONS FOR PATIENTS’ CLINICAL EVALUATION.
Authors: Palmieri Raffaele , Del Principe Ilaria , Maurillo Luca , Venditti Adriano , Buccisano Francesco 
Published: August 2023

Therapy-related myeloid neoplasms (t-MNs) encompass a specific sub-group of myeloid malignancies arising after exposure to radio/cytotoxic agents for the treatment of unrelated diseases.
Such malignancies present unique features, including advanced age, high comorbidities burden, and unfavorable genetic profiles. All these features justify the need for a specific diagnostic work-up and dedicated treatment algorithms. However, as new classification systems recognize the unique clinical characteristics exhibited by t-MNs patients, how to assess fitness status in this clinical setting is largely unexplored. Optimizing fitness assessment would be crucial in the management of t-MNs patients, considering that factors usually contributing to a worse or better outcome (like age, comorbidities, and treatment history) are patient-specific.
In the absence of specific tools for fitness assessment in this peculiar category of AML, the aim of this review is to describe all those factors related to patient, treatment and disease that allow planning treatments with an optimal risk/benefit ratio.
A prospective comparative study on management of midshaft clavicle fractures: Conservative versus surgical

Published: August 2023

Abstract

Background:
With nonunion rates up to 15% and unsatisfactory patient-reported outcomes in around a third of patients treated conservatively, recent research on displaced midshaft clavicular fractures points to a considerable unmet medical need. These findings have prompted a recent increase in surgical fixation of displaced midshaft clavicular fractures.

Objective:
In addition to open reduction and plate fixation, intramedullary pins, wires, or nails may also be used to treat clavicle fractures. In this study, we compare the clinical, radiological, and functional results of midshaft clavicular fractures managed with open reduction and plate fixation versus conservative therapy, as well as their overall complication rates.

Materials and Methods:
All skeletally mature patients presenting to outpatient department/inpatient department with clavicle fracture less than 3 weeks old and displacement/loss of cortical contact between fractured ends of more than 2 cm were included in the study. Patients were randomly allocated to either conservative or surgical management. For conservative management, strapping of the involved side and application of figure-of-eight bandage was done. The minimum follow-up requirement of all patients was 1 year. The clinical assessment involved the assessment of complications, grading of results according to Constant and Murley score as well as the Disabilities of the Arm, Shoulder, and Hand score (DASH score). A radiological assessment for the union of the fracture was also done.

Results:
In the conservative management group (n = 52), the mean age of the group was 36 years (range, 19–58 years), and the mean follow-up was 1.6 years (range, 1–2.2 years). At 1 year follow-up, the mean DASH score was 7.9 ± 2.1, and the mean Constant score was 90.2 ± 15. The overall complication rate was found to be 21/52 (40.3%) in the operative management group. In the operative management group (n = 50), the mean age of the group was 42 years (range, 24–57 years) and the mean follow-up was 1.3 years (range, 1.1–1.8 years). At 1-year follow-up, the mean DASH score was 10.8 ± 1.1, and the mean Constant score was 93.1 ± 13. The overall complication rate was found to be 14/50 (28%) in the operative management group. In comparison, the overall rate of complications was significantly lower in the operative management group compared with the conservative management group (P = 0.001).

Conclusions:
Conservative management of midshaft clavicular fractures was associated with similar clinical and radiological outcomes compared to operative management. However, the overall complication rate was lower for operatively managed patients.
Orthopedic research output from SAARC countries in the last 25 years: 1996-2021
Authors: Vaishya Raju , Vaish Abhishek 
Published: August 2023

Abstract
A large proportion of the global population (21%) live in the eight South Asian Association for Regional Cooperation (SAARC) nations in South Asia. The publications related to orthopedics and sports medicine in the last 25 years from these countries have been only 1.45%. There is an imminent need to encourage research and publications from the SAARC nations. This review has attempted to identify the challenges and gaps, and has attempted to provide remedies to overcome these. More focus on research and publication is needed from the SAARC nations. Individuals, organizations, and governments should make sincere efforts to publish their research in impact journals, and no research should go wasted; unpublished or in predatory journals. More journals in the field of orthopedics and sports medicine are required from SAARC. Collaborations between institutions (national and international) are useful in getting impactful research and subsequent publications.
