Abstract
One of the most poorly understood aspects of low-mass star formation is how multiple-star systems are formed. Here we present the results of Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 observations toward a forming quadruple protostellar system, G206.93-16.61E2, in the Orion B molecular cloud. ALMA 1.3 mm continuum emission reveals four compact objects, of which two are Class I young stellar objects and the other two are likely in prestellar phase. The 1.3 mm continuum emission also shows three asymmetric ribbon-like structures that are connected to the four objects, with lengths ranging from ∼500 to ∼2200 au. By comparing our data with magnetohydrodynamic simulations, we suggest that these ribbons trace accretion flows and also function as gas bridges connecting the member protostars. Additionally, ALMA CO J = 2−1 line emission reveals a complicated molecular outflow associated with G206.93-16.61E2, with arc-like structures suggestive of an outflow cavity viewed pole-on.

Abstract
Recently, the first JWST measurement of thermal emission from a rocky exoplanet was reported. The inferred dayside brightness temperature of TRAPPIST-1 b at 15 μm is consistent with the planet having no atmosphere and therefore no mechanism by which to circulate heat to its nightside. In this Letter, we compare TRAPPIST-1 b's measured secondary eclipse depth to predictions from a suite of self-consistent radiative-convective equilibrium models in order to quantify the maximum atmospheric thickness consistent with the observation. We find that plausible atmospheres (i.e., those that contain at least 100 ppm CO2) with surface pressures greater than 0.3 bar are ruled out at 3σ, regardless of the choice of background atmosphere, and a Mars-like thin atmosphere with surface pressure 6.5 mbar composed entirely of CO2 is also ruled out at 3σ. Thicker atmospheres of up to 10 bar (100 bar) are consistent with the data at 1σ (3σ) only if the atmosphere lacks any strong absorbers across the mid-IR wavelength range—a scenario that we deem unlikely. We additionally model the emission spectra for bare-rock planets of various compositions. We find that a basaltic, metal-rich, and Fe-oxidized surface best matches the measured eclipse depth to within 1σ, and the best-fit gray albedo is 0.02 ± 0.11. We conclude that planned secondary eclipse observations at 12.8 μm will serve to validate TRAPPIST-1 b's high observed brightness temperature, but are unlikely to further distinguish among the consistent atmospheric and bare-rock scenarios.
Dimming of Continuum Captured in Mrk 841: New Clues on the Nature of the Soft X-Ray Excess
Authors: Mehdipour Missagh , Kriss Gerard A. , Kaastra Jelle S. , Costantini Elisa , Mao Junjie 
Published: July 2023

Abstract
We report on a remarkable change in the spectral energy distribution (SED) of Mrk 841, providing new insights on how the soft X-ray excess emission in active galactic nuclei (AGNs) is produced. By Swift monitoring of a sample of Seyfert-1 galaxies, we found an X-ray spectral hardening event in Mrk 841. We thereby triggered our XMM-Newton, NuSTAR, and Hubble Space Telescope observations in 2022 to study this event. Our previous investigations of such events in other AGNs had shown that they are caused by obscuring winds. However, the event in Mrk 841 has different spectral characteristics and origin. We find it is the soft X-ray excess component that has become dimmer. This is, importantly, accompanied by a similar decline in the optical/UV continuum, suggesting a connection to the soft X-ray excess. In contrast, there is relatively little change in the X-ray power law and the reflection components. Our SED modeling suggests that the soft X-ray excess is the high-energy extension of the optical/UV disk emission, produced by warm Comptonization. We find the temperature of the disk dropped in 2022, explaining the observed SED dimming. We then examined the Swift data, taken over 15 yr, to further decipher the UV and X-ray variabilities of Mrk 841. A significant relation between the variabilities of the X-ray spectral hardness and that of the UV continuum is found, again suggesting that the soft excess and the disk emission are interlinked. This is readily explicable if the soft excess is produced by warm Comptonization.

Abstract
We present an early analysis on the search for high-redshift galaxies using the deepest public JWST imaging to date, the NGDEEP field. These data consist of six-band NIRCam imaging on the Hubble Ultra Deep Field Parallel 2 (HUDF-Par2), covering a total area of 6.3 arcmin2. Based on our initial reduction of the first half of this survey, we reach 5σ depths up to mag = 29.5–29.9 between 1 and 5 μm. Such depths present an unprecedented opportunity to begin exploring the very early universe with JWST. As such, we find high-redshift galaxies by examining the spectral energy distribution of all F444W detections and present 16 new z > 8.5 galaxies identified using two different photometric redshift codes: LePhare and EAZY combined with other significance criteria. The highest-redshift object in our sample is at

Comparing to previous work in the HUDF-Par2, we find 21 6 < z < 9 candidates including two z = 8 major mergers. One of these merger candidates has an additional two z = 8 sources within 30″, indicating that it may form part of an overdensity. We also compare our results to theory, finding no significant disagreement with a few cold-dark-matter-based models. The discovery of these objects demonstrates the critical need for deeper, or similar depth but wider-area, JWST surveys to explore the early universe.
Binning is Sinning: Redemption for Hubble Diagram Using Photometrically Classified Type Ia Supernovae
Authors: Kessler R. , Vincenzi M. , Armstrong P. 
Published: July 2023

Abstract
Bayesian Estimation Applied to Multiple Species (BEAMS) is implemented in the BEAMS with Bias Corrections (BBC) framework to produce a redshift-binned Hubble diagram (HD) for Type Ia supernovae (SNe Ia). BBC corrects for selection effects and non–SN Ia contamination, and systematic uncertainties are described by a covariance matrix with dimension matching the number of BBC redshift bins. For spectroscopically confirmed SN Ia samples, a recent “Binning is Sinning” article showed that an unbinned HD and covariance matrix reduces the systematic uncertainty by a factor of ∼1.5 compared to the binned approach. Here we extend their analysis to obtain an unbinned HD for a photometrically identified sample processed with BBC. To test this new method, we simulate and analyze 50 samples corresponding to the Dark Energy Survey (DES) with a low-redshift anchor; the simulation includes SNe Ia, and contaminants from core-collapse SNe and peculiar SNe Ia. The analysis includes systematic uncertainties for calibration and measures the dark energy equation of state parameter (w). Compared to a redshift-binned HD, the unbinned HD with nearly 2000 events results in a smaller systematic uncertainty, in qualitative agreement with BHS21, and averaging results among the 50 samples we find no evidence for a w-bias. To reduce computation time for fitting an unbinned HD with large samples, we propose an HD-rebinning method that defines the HD in bins of redshift, color, and stretch; the rebinned HD results in similar uncertainty as the unbinned case, and shows no evidence for a w-bias.
Magnetic Braking during Direct Collapse Black Hole Formation
Authors: Latif Muhammad A. , Schleicher Dominik R. G. 
Published: July 2023

Abstract
Magnetic fields are expected to be efficiently amplified during the formation of the first massive black holes via the small-scale dynamo and in the presence of strong accretion shocks occurring during gravitational collapse. Here, we analyze high-resolution cosmological magnetohydrodynamical simulations of gravitational collapse in atomic cooling halos, exploring the dynamical role of magnetic fields, particularly concerning the effect of magnetic braking and angular momentum transport. We find that after the initial amplification, magnetic fields contribute to the transport of angular momentum and reduce it compared to pure hydrodynamical simulations. However, the magnetic and Reynolds torques do not fully compensate for the inward advection of angular momentum, which still accumulates over timescales of ∼1 Myr. A Jeans analysis further shows that magnetic pressure strongly contributes to suppressing fragmentation on scales of 0.1–10 pc. Overall, the presence of magnetic fields thus aids in the transport of angular momentum and favors the formation of massive objects.
Shock Synthesis of Organic Molecules by Meteoroids in the Atmosphere of Titan
Authors: Flowers Erin E. , Chyba Christopher F. 
Published: July 2023

Abstract
Thermochemical modeling and shock-tube experiments show that shocks applied to N2/CH4 gas mixtures can synthesize organic molecules. Sufficiently large, hypersonic meteoroids entering the atmosphere of Saturn’s moon Titan should therefore drive organic chemistry. To do so meteoroids must be sufficiently large compared to the atmospheric mean free path at a given altitude to generate shocks, and deposit enough energy per path length to produce temperatures high enough to excite and dissociate the relevant molecules. The Cassini spacecraft imaged multiple meteoroid impacts on Saturn’s rings, allowing for the first time an empirical estimate to be made of the flux and size–frequency distributions of meteoroids in the millimeter-to-meter size range. We combine these results with an atmospheric entry model and thermochemical and experimental shock production efficiencies for N2/CH4 atmospheres and calculate the shock production rates for HCN, C2H2, and C2H4 as well as the resulting H2 generation. We find that meteoroids may be producing these molecules at as much as ∼1% the production rate of photochemistry driven by UV photons, and may be depositing more energy than magnetospheric ions and 90–100 nm UV photons. Moreover, these meteoroids produce these organic molecules hundreds of kilometers lower in Titan’s atmosphere than the relevant UV photons and magnetospheric ions penetrate, with peak production occurring between 200 and 500 km altitudes, i.e., at the observed haze layer. Meteoroid-driven shock generation of molecules may therefore be crucial to understanding Titan’s atmospheric chemistry.
Detecting medication non-adherence in schizophrenia: A comparison of different methods among outpatients from a North Indian center
Authors: Chauhan Nidhi , Chakrabarti Subho , Grover Sandeep 
Published: July 2023

ABSTRACT

Background:
The rates of medication non-adherence among Indian patients with schizophrenia are high, and its detection poses problems. Comparisons of suitable measures to detect medication non-adherence in schizophrenia from Indian outpatient settings are scarce.

Aim:
This study compared simple and inexpensive methods of detecting medication non-adherence in schizophrenia among outpatients from a tertiary-care center in North India.

Materials and Method:
A longitudinal comparison of two self-reports, the Morisky Medication Adherence Questionnaire and the Drug Attitude Inventory-10, clinicians’ ratings employing the Compliance Rating Scale, and clinic-based pill counts was conducted among 70 outpatients with schizophrenia. The rates and detection of medication non-adherence, associations with determinants of treatment non-adherence, and agreement between measures were examined at intake and after six months of follow-up (n = 53).

Results:
The self-reports had greater ability to detect medication adherence (specificity 41–65%; positive predictive values 25–51%; negative likelihood ratios 0.86–1.14) and moderate ability to detect medication non-adherence (sensitivity 27–65%; negative predictive values 49–69%; positive likelihood ratios 0.78–1.10). They yielded higher medication non-adherence rates, detected changes in medication non-adherence over time, and were associated with the other measures and the well-known correlates of medication non-adherence. Clinicians’ ratings and pill counts had high sensitivity (56–90%) but low specificity (35–49%) to detect medication non-adherence.

Conclusion:
Self-reports are comparatively better screening options for detecting medication non-adherence among Indian outpatients with schizophrenia. However, the sequential use of different measures could lead to better recognition of medication non-adherence.
Sensitivity of mixing times of Cayley graphs
Authors: Hermon Jonathan , Kozma Gady 
Published: July 2023

AbstractWe show that the total variation mixing time is not quasi-isometry invariant, even for Cayley graphs. Namely, we construct a sequence of pairs of Cayley graphs with maps between them that twist the metric in a bounded way, while the ratio of the two mixing times goes to infinity. The Cayley graphs serving as an example have unbounded degrees. For non-transitive graphs, we construct bounded degree graphs for which the mixing time from the worst starting point for one graph is asymptotically smaller than the mixing time from the best starting point of the random walk on a network obtained by increasing some of the edge weights from 1 to

Pierres vivantes
Authors: Adell Nicolas , Charlier Zeineddine Laurence 
Published: July 2023

Dans les Andes, certaines pierres sont « élevées » par les bergers : lorsqu’ils en aperçoivent dans la montagne, ils ont la charge de les emporter chez eux, de les nourrir et d’en prendre soin, car ces « êtres vivants » ont faim et ont besoin d’attention. Si ces pierres vivantes ne remettent pas brutalement en cause les limites du vivant que les humains manifestent, elles remettent en question certains processus communs : elles sont élevées et nourries, mais ne grandissent pas. Elles ajoutent discrètement leurs propriétés minérales à ce qu’être vivant veut dire et ouvrent la possibilité de prendre en compte de nouvelles qualités pour faire la vie. En contexte européen, d’autres pierres ont également cette capacité à inquiéter les frontières du monde vivant : les pierres « branlantes » ou « clouées » défient ainsi les lois d’un équilibre qui semble précaire tandis que les pierres « percées » font entendre leur voix lorsque s’engouffre le vent par quelques-unes de leurs cavités. Dans cet article, il s’agit d’explorer et d’étendre le champ du vivant à partir des propriétés sensibles qui caractérisent les pierres : la durée, la dureté, la fixité apparente. En rendant compte des mouvements que les acteurs, dans les Andes et en Europe, prêtent à certaines pierres, il est proposé une approche descriptive des manières dont est perçue ou ressentie la mobilité lithique.
La Maison buissonnière hors des sentiers battus
Authors: Krymko-Bleton Irène 
Published: July 2023

La pratique préventive de la Maison buissonnière, qui reçoit à Montréal depuis une trentaine d’années des bébés et des enfants d’âge pré-oedipien accompagnés de leurs proches, se situe toujours hors des sentiers battus, autant des pratiques psychanalytiques courantes que des pratiques socio-éducatives prévalentes au Québec. Adossé sur les enseignements de Françoise Dolto et sur les théories du développement précoce, l’accueil de familles vise que le bébé ou le petit enfant puisse « dérouler sa question » et que le parent puisse l’entendre, afin que les malentendus entre lui et sa famille ne se nouent pas ultérieurement en symptômes. L’article décrit les principes qui soutiennent le travail des « accueillants », les illustre par des exemples tirés de la pratique au quotidien et présente quelques-unes de ses bases théoriques.
Aménagement, urbanisme et « dialogue citoyen » à Nantes : d’ambigüités en contradictions
Authors: Fache Jacques 
Published: July 2023

Nantes et la métropole nantaise ont développé le « dialogue citoyen », outil pour associer la population aux décisions, en particulier dans la conception de la ville. Cet outil intermédiaire entre le top-down classique et la démocratie participative évite les sujets économiques et culturels pourtant essentiels pour le modèle nantais. Au-delà des contraintes techniques, c’est certainement dans le caractère contradictoire des modèles mobilisés à Nantes (accumulation métropolitaine contre ville écologique et sociale) que se niche la discrétion des autorités sur ce sujet.
Préservation des sols et perception des services écosystémiques des sols dans les espaces périurbains
Authors: Serrano José , Poyat Yannick , Boutet Didier 
Published: July 2023

L’article porte sur la question de la préservation des sols face à leur consommation pour l’urbanisation. En dépit d’une législation qui pousse de plus en plus à la sobriété foncière, l’artificialisation des sols se poursuit à un rythme élevé en France. Les approches par la reconnaissance des services écosystémiques sont développées pour améliorer la préservation des ressources naturelles. Ces approches arrivent-elles à infléchir la consommation des sols lorsqu’elles sont appropriées par les élus locaux ? Quelle est la diversité des perceptions des services écosystémiques et des stratégies de développement des élus locaux ? À travers le concept de services écosystémiques, nous analysons les représentations et les usages des sols des élus pour six territoires périurbains français. En croisant les discours sur les services écosystémiques des sols et leur consommation effective, nous montrons la limite d’une approche normative des services écosystémiques pour la régulation des usages des sols.
