Abstract
We present observations of the J = 1 – 0 transition lines of 12CO, 13CO, and C18O toward the Galactic region of 153.°60 ≤ l ≤ 156.°50 and 1.°85 ≤ b ≤ 3.°50, using the Purple Mountain Observatory 13.7 m millimeter telescope. Based on the 13CO data, one main filament and five subfilaments are found together as a network structure in the velocity interval of [−42.5, −30.0] km s−1. The kinematic distance of this molecular cloud is estimated to be ∼4.5 kpc. The median length, width, excitation temperature, and line mass of these filaments are ∼49 pc, ∼2.9 pc, ∼8.9 K, and ∼39 M
⊙ pc−1, respectively. The velocity structures along these filaments exhibit oscillatory patterns, which are likely caused by the fragmentation or accretion process along these filaments. The maximum accretion rate is estimated to be ∼700 M
⊙ pc−1. A total of ∼162 13CO clumps and ∼103 young stellar objects are identified in this region. Most of the clumps are in gravitationally bound states. Three H ii regions (G154.359+2.606, SH2-211, and SH2-212) are found to be located in the apexes of the filaments. Intense star-forming activity is found along the entire filamentary cloud. The observed results may help us to better understand the link between filaments and massive star formation.

Abstract
In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (∼600 Myr to 2 Gyr old) star clusters, some younger clusters even exhibit split main sequences (MSs). Different stellar rotation rates are proposed to account for the bifurcated MS pattern, with red and blue MSs (rMS and bMS) populated by fast and slowly rotating stars, respectively. Using photometry from Gaia Early Data Release 3, we report a Galactic open cluster with a bifurcated MS, NGC 2422 (∼90 Myr). We exclude the possibilities that the bifurcated MS pattern is caused by photometric noise or differential reddening. We aim to examine if stellar rotation can account for the split MS. We use spectra observed with the Canada–France–Hawaii Telescope and the Southern African Large Telescope and directly measured

values are weakly correlated with their loci in the color–magnitude diagram because of contamination caused by a large fraction of rMS stars with low projected rotational velocities. Based on the spectral energy distribution fitting method, we suggest that these slowly rotating stars at the rMS may hide a binary companion, which breaks the expected

Binary Interaction Dominates Mass Ejection in Classical Novae
Authors: Shen Ken J. , Quataert Eliot 
Published: October 2022

Abstract
Recent observations suggest our understanding of mass loss in classical novae is incomplete, motivating a new theoretical examination of the physical processes responsible for nova mass ejection. In this paper, we perform hydrodynamical simulations of classical nova outflows using the stellar evolution code MESA. We find that, when the binary companion is neglected, white dwarfs with masses ≳0.8 M
⊙ successfully launch radiation-pressure-driven optically thick winds that carry away most of the envelope. However, for most of the mass-loss phase, these winds are accelerated at radii beyond the white dwarf’s Roche radius assuming a typical cataclysmic variable donor. This means that, before a standard optically thick wind can be formed, mass loss will instead be initiated and shaped by binary interaction. An isotropic, optically thick wind is only successfully launched when the acceleration region recedes within the white dwarf’s Roche radius, which occurs after most of the envelope has already been ejected. The interaction between these two modes of outflow—a first phase of slow, binary-driven, equatorially focused mass loss encompassing most of the mass ejection and a second phase consisting of a fast, isotropic, optically thick wind—is consistent with observations of aspherical ejecta and signatures of multiple outflow components. We also find that isolated lower-mass white dwarfs ≲0.8 M
⊙ do not develop unbound optically thick winds at any stage, making it even more crucial to consider the effects of the binary companion on the resulting outburst.
High-redshift Galaxies from Early JWST Observations: Constraints on Dark Energy Models

While such a result is based on early measurements that are still affected by uncertainties currently under consideration by several observational groups, its confirmation would have a strong impact on cosmology. Here we show that—under the most conservative assumptions and independently of the baryon physics involved in galaxy formation—such galaxy abundance is not only in tension with the standard ΛCDM cosmology but provides extremely tight constraints on the expansion history of the universe and on the growth factors corresponding to a wide class of Dynamical Dark Energy (DDE) models.

Published: October 2022

Abstract
In 2022 September, the DART spacecraft (NASA’s contribution to the Asteroid Impact & Deflection Assessment (AIDA) collaboration) will impact the asteroid Dimorphos, the secondary in the Didymos system. The crater formation and material ejection will affect the orbital period. In 2027, Hera (ESA’s contribution to AIDA) will investigate the system, observe the crater caused by DART, and characterize Dimorphos. Before Hera’s arrival, the target properties will not be well-constrained. The relationships between observed orbital change and specific target properties are not unique, but Hera’s observations will add additional constraints for the analysis of the impact event, which will narrow the range of feasible target properties. In this study, we use three different shock physics codes to simulate momentum transfer from impactor to target and investigate the agreement between the results from the codes for well-defined target materials. In contrast to previous studies, care is taken to use consistent crushing behavior (e.g., distension as a function of pressure) for a given porosity for all codes. First, we validate the codes against impact experiments into a regolith simulant. Second, we benchmark the codes at the DART impact scale for a range of target material parameters (10%–50% porosity, 1.4–100 kPa cohesion). Aligning the crushing behavior improves the consistency of the derived momentum enhancement between the three codes to within +/−5% for most materials used. Based on the derived mass–velocity distributions from all three codes, we derive scaling parameters that can be used for studies of the ejecta curtain.

Abstract
The search for exploitable deposits of water and other volatiles at the Moon’s poles has intensified considerably in recent years, due to the renewed strong interest in lunar exploration. With the return of humans to the lunar surface on the horizon, the use of locally available resources to support long-term and sustainable exploration programs, encompassing both robotic and crewed elements, has moved into focus of public and private actors alike. Our current knowledge about the distribution and concentration of water and other volatiles in the lunar rocks and regolith is, however, too limited to assess the feasibility and economic viability of resource-extraction efforts. On a more fundamental level, we currently lack sufficiently detailed data to fully understand the origins of lunar water and its migration to the polar regions. In this paper, we present LUVMI-X, a mission concept intended to address the shortage of in situ data on volatiles on the Moon that results from a recently concluded design study. Its central element is a compact rover equipped with complementary instrumentation capable of investigating both the surface and shallow subsurface of illuminated and shadowed areas at the lunar south pole. We describe the rover and instrument design, the mission’s operational concept, and a preliminary landing-site analysis. We also discuss how LUVMI-X fits into the diverse landscape of lunar missions under development.
The Horizontal Wavelength Spectrum of Gravity Wave Activity in Mars’s Lower Atmosphere: The Perspective from MGS–TES Nadir Observations

Published: October 2022

Abstract
Connecting upper-atmospheric gravity waves (GW) to their lower- and middle-atmospheric (0–30 and 30–100 km altitude) origins can improve understanding of the evolution of Mars’s atmosphere as well as its present thermal structure and general circulation. A recent study using observations from the Mars Climate Sounder (MCS) on board the Mars Reconnaissance Orbiter (MRO) characterized the climatology of lower-atmospheric GW with 10–100 km horizontal wavelengths, but GW observed in the upper atmosphere have horizontal wavelengths of up to 500 km, motivating more careful attention to the horizontal wavelength spectrum of lower-atmospheric GW. A previous study of observations by the Thermal Emission Spectrometer (TES) on Mars Global Surveyor (MGS) reported substantial interannual variability in the horizontal wavelength spectrum of wave activity defined broadly, including GW. Here, we derive the horizontal wavelength spectrum of wave activity from the brightness temperature variance spectrum of MGS–TES observations resampled to the MRO–MCS spectral channels during L

s
= 120°–150°, Mars Years 24 and 25. Lower-atmospheric wave activity is strongest at wavelengths <200 km, a population which resembles that observed by MRO–MCS and is likely GW activity. This short-wavelength population is distinct from a wave population with wavelengths >1000 km, which appears to be a mixture of tides and planetary waves. We find that interannual variability in GW activity previously identified using MGS–TES data largely arises from a change in the instrumental noise characteristics of MGS–TES during the first quarter of MY 25.
Developing Data-driven Artificial Neural Network for a High Throughput Retrieval of Aerosol Optical Depth and Surface Temperature of Mars
Authors: Moreno Rafael , Smith Michael D. , Atwood Samuel A. , Mason Emily L. , Nehmetallah George 
Published: October 2022

Abstract
In this work, we aim to develop artificial neural network (ANN) techniques to reproduce the retrieval results of physical quantities from spacecraft observations of solar system bodies using radiative transfer methods. The particular application here is the retrieval of dust optical depth, water ice optical depth, and surface temperature on Mars using daytime observations obtained by the Thermal Emission Spectrometer on board the Mars Global Surveyor. Compared against the results obtained from traditional radiative transfer retrieval techniques, our ANN successfully recovered the three quantities using daytime observations. The principal advantage of these machine-learning algorithms is their complete automation and high throughput. Therefore, the algorithms presented here would be useful for very large data sets and would make practical the sampling of many different approximations or boundary conditions related to a given observation data set and retrieval problem.

Published: October 2022

Introduction: The goal of this study was to evaluate the side effects of application of the Pfizer BioNTech vaccine on the workers at a Mexican hospital.
Methodology: A cross-sectional study was carried out, in which 1351 workers from a tertiary care center in the Mexican southeast were included. Sociodemographic data, comorbidities, and side effects after the Pfizer BioNTech vaccine were obtained through an online survey. The variables were analyzed through descriptive statistics. The presence or absence of side effects was analyzed through the Chi-square test or t-test, as appropriate. The result was considered statistically significant at p < 0.05.
Results: A total of 1351 health workers participated in the online survey. The mean age was 37.8 ± 10.9 years and 56.4% were women. Among them, 8.2% suffered from high blood pressure. In addition, 76.7% manifested pain in the application area. The presence of side effects was associated with the female gender (p < 0.01). Side effects were more prevalent in younger age (37.2 ± 10.7) than older age (41.5 ± 10.8) (p < 0.01). There was no association with the presence of comorbidities (p > 0.05).
Conclusions: The data suggest that pain in the application area is the most frequent side effect among workers in a Mexican hospital who received the Pfizer BioNTech vaccine against COVID-19. In addition, we observed sialorrhea as a side effect in the studied population and this had not previously been reported. The highest number of adverse events occurred between 24 to 72 hours after application.

Authors: Hosoglu Salih , Mahmood Mohammed Khalid 
Published: October 2022

Introduction: COVID-19 incidence was relatively high among dentists in Iraq, reflecting the high number of cases in the community. Therefore, possible epidemiological features of COVID-19 infection were investigated among dentists in Iraqi Kurdistan Region.
Methodology: A cross-sectional study has been conducted among dentists using a structured questionnaire. The questionnaire included demographic and working characteristics, self-reported COVID-19 history, and prevention practices toward SARS-CoV-2 during the pandemic. An online questionnaire was developed and spread with a snowball method among dentists.
Results: We analyzed the responses of 83 participants (31 women and 52 men, mean age 33.8 ± 6.8 years). They had a mean of 10.6 ± 6.5 years of work experience and 20.2 ± 12.6 hours of weekly working time. In total, 46 (55.4%) of the participants reported COVID-19 infection. Only 29 (34.9%) participants always followed the hygiene rules. The most common personal precautions were mask-wearing (98.8%) and hand hygiene as a part of institutional protective precaution (51.8%). Of the infected dentists, 24 (52.2%) did not know the source of infection. Of the remaining 16 (34.8%) were infected from family and/or friends circle, and five (10.9%) from patients. Eleven of them (23.9%) reported transmitting the infection to at least one person. In the multivariate analyses, working in Sulaymaniyah Province (p = 0.031) and working only in a public hospital (p = 0.029) were significant risk factors for COVID-19 infection.
Conclusions: The high risk of COVID-19 infection among dentists in the Iraqi Kurdistan Region relates to their family and friends rather than their occupation.

FAIR Points: From sdo:LearningResource to FAIR Digital Object
Authors: El-Gebali Sara , Erdmann Christopher , Winston Donald 
Published: October 2022

The FAIRPoints organization, co-founded by the authors, aims to provide a platform for conversations to take place around realistic and pragmatic implementations of the FAIR (Findable, Accessible, Interoperable, Reusable) principles. The uniqueness of the FAIRPoints effort stems from an additional aim: to capture conversation contributions in the form of “bite-sized” objects – “points” – in a way that facilitates dynamic composition by instructors for the delivery of audience-customized training experiences. Thus, FAIRPoints aims to cultivate pragmatic learning resources to help realize the FAIR principles in practice, both through

inviting speakers to prime and lead discussions focused on choices/challenges regarding FAIR, and

amplifying downstream value potential by serializing “points” made during such events as FAIR resources.

amplifying downstream value potential by serializing “points” made during such events as FAIR resources.
Currently, event outcomes are serialized as LearningResource-typed JSON-LD objects in the schema.org sense, i.e. sdo:LearningResource, where @prefix sdo: &lt;https://schema.org/&gt; ., and conform to the bioschemas.org TrainingMaterial profile. However, any differences in participant perspectives must be reconciled, via git revision control, towards a single “view” of a sdo:LearningResource. This situation is at odds with other explicit aims of the FAIRPoints organization such as including diverse voices and collecting heterogeneous input from a global perspective.
Using the FAIR Digital Object (FDO) approach, a FAIRPoints sdo:LearningResource instance may be the Object to which an Identifier points, through an FDO Identifier Record, and sdo:LearningResource may be the FDO Type. Crucially, there may be a multiplicity of Metadata records pointed to by an FDO Identifier Record and thus a formal mechanism to cultivate and publish diverse perspectives.
This presentation will outline FAIRPoints’ approach to FDO implementation for learning resources and its relation to published practice. Specifically, in relation to the FAIR Digital Twins approach*1, our approach may be seen as the stewardship of a “fluid graph” of learning-resource “knowlets” with support for “qua” projection in service of e.g. an instructor’s dynamic composition of training material for a targeted workshop.
Karl Rahner et la théologie de l’inspiration
Authors: Monzani Paolo 
Published: October 2022

L’article propose une appréciation de la théologie de l’inspiration de K. Rahner, notamment à partir d’un texte capital récemment traduit en français. Sa proposition comporte un déplacement d’attention de la psychologie des hagiographes vers la dimension corporative de l’Église apostolique et une distinction entre l’action de Dieu « Auctor » de celle des hommes « auteurs ». Si la contribution de Rahner peut constituer un point de repère sur un sujet apparemment oublié dans les dernières décennies, l’article évoque aussi des nouvelles pistes qui demandent à être explorées aujourd’hui, notamment le rôle des lecteurs dans le processus d’inspiration.
L’assurance chômage de 1979 à 2021 : quelles évolutions des droits ?
Authors: Grégoire Mathieu , Vivés Claire 
Published: October 2022

Cet article porte sur l’évolution des droits des salariés à l’assurance chômage de 1979 à 2021 étudiée au moyen d’un simulateur déterminant les droits générés, pour toute trajectoire d’emploi, par les différentes réglementations successives. Il montre que les droits des salariés à l’emploi discontinu ont beaucoup varié alors que ceux des salariés à l’emploi stable ont connu une remarquable constance et que l’idée d’une amélioration linéaire des droits des salariés à l’emploi discontinu s’avère constituer un mythe. En revanche, en 40 ans, la logique de l’indemnisation a été profondément bouleversée en passant d’une logique d’assurance à une logique de compte épargne. Il convient ainsi de distinguer deux catégories de salariés à l’emploi discontinu souvent confondues : les « précaires » (en intermittence permanente) et les « chômeurs activés » (au passé d’emploi stable) dont les droits ont évolué différemment.
Le capitalisme est-il un système intrinsèquement violent ? Une lecture benjaminienne du concept d’accumulation primitive chez Karl Marx, Rosa Luxemburg et David Harvey
Authors: Sobel Richard 
Published: October 2022

La théorie économique marxiste rend compte des rapports entre capitalisme et violence à l’aide notamment du concept d’accumulation primitive. Cet article se propose de montrer comment ce concept s’est construit et étoffé en analysant trois étapes : d’abord son élaboration initiale par Karl Marx (l’accumulation primitive comme préhistoire du capital), ensuite une première extension par Rosa Luxemburg (l’accumulation primitive comme mouvement actuel d’extension géographique de la logique du capital du centre vers la périphérie), et enfin une seconde extension par David Harvey (l’accumulation primitive comme mouvement de recolonisation « intérieure » et d’« accumulation par dépossession »). L’article propose d’articuler ces trois étapes à partir de la dialectique entre droit et violence telle que l’a problématisée le philosophe Walter Benjamin (2018). Codes JEL : B14, B24, B5.
