Magnetic Effects Promote Supermassive Star Formation in Metal-enriched Atomic-cooling Halos
Authors: Hirano Shingo , Machida Masahiro N. , Basu Shantanu 
Published: July 2023

Abstract
Intermediate-mass black holes (with ≥105
M
⊙) are promising candidates for the origin of supermassive black holes (with ∼109
M
⊙) in the early universe (redshift z ∼ 6). Chon & Omukai first pointed out direct collapse black hole (DCBH) formation in metal-enriched atomic-cooling halos (ACHs), which relaxes the DCBH formation criterion. On the other hand, Hirano et al. showed that magnetic effects promote DCBH formation in metal-free ACHs. We perform a set of magnetohydrodynamical simulations to investigate star formation in magnetized ACHs with metallicities Z/Z
⊙ = 0, 10−5, and 10−4. Our simulations show that the mass accretion rate onto the protostars becomes lower in metal-enriched ACHs than in metal-free ACHs. However, many protostars form from gravitationally and thermally unstable metal-enriched gas clouds. Under such circumstances, the magnetic field rapidly increases as magnetic field lines wind up due to the spin of protostars. The region with the amplified magnetic field expands outwards due to the orbital motion of protostars and the rotation of the accreting gas. The amplified magnetic field extracts angular momentum from the accreting gas, promotes the coalescence of low-mass protostars, and increases the mass growth rate of the primary protostar. We conclude that the magnetic field amplification is always realized in metal-enriched ACHs regardless of the initial magnetic field strength, which affects the DCBH formation criterion. In addition, we find a qualitatively different trend from the previous unmagnetized simulations in that the mass growth rate is maximal for extremely metal-poor ACHs with Z/Z
⊙ = 10−5.
Tidal Spin-up of Black Hole Progenitor Stars
Authors: Ma 马 Linhao 林昊 , Fuller Jim 
Published: July 2023

Abstract
Gravitational wave observations indicate the existence of merging black holes (BHs) with high spin (a ≳ 0.3), whose formation pathways are still an open question. A possible way to form those binaries is through the tidal spin-up of a Wolf–Rayet (WR) star by its BH companion. In this work, we investigate this scenario by directly calculating the tidal excitation of oscillation modes in WR star models, determining the tidal spin-up rate, and integrating the coupled spin–orbit evolution for WR–BH binaries. We find that, for short-period orbits and massive WR stars, the tidal interaction is mostly contributed by standing gravity modes, in contrast to Zahn’s model of traveling waves, which is frequently assumed in the literature. The standing modes are less efficiently damped than traveling waves, meaning that prior estimates of tidal spin-up may be overestimated. We show that tidal synchronization is rarely reached in WR–BH binaries, and the resulting BH spins have a ≲ 0.4 for all but the shortest-period (P
orb ≲ 0.5 day) binaries. Tidal spin-up in lower-mass systems is more efficient, providing an anticorrelation between the mass and spin of the BHs, which could be tested in future gravitational wave data. Nonlinear damping processes are poorly understood but may allow for more efficient tidal spin-up. We also discuss a new class of gravito-thermal modes that appear in our calculations.

Abstract
We report Atacama Large Millimeter/submillimeter Array Band 3 observations of CO(6−5), CO(7−6), and [C i](2−1) in B14-65666 (“Big Three Dragons”), one of the brightest Lyman-break galaxies at z > 7 in the rest-frame ultraviolet continuum, far-infrared continuum, and emission lines of [O iii] 88 μm and [C ii] 158 μm. CO(6−5), CO(7−6), and [C i](2−1), whose 3σ upper limits on the luminosities are approximately 40 times fainter than the [C ii] luminosity, are all not detected. The L
[C II]/L
CO(6–5) and L
[C II]/L
CO(7–6) ratios are higher than the typical ratios obtained in dusty star-forming galaxies or quasar host galaxies at similar redshifts, and they may suggest a lower gas density in the photodissociated region in B14-65666. By using the (1) [C ii] luminosity, (2) dust mass-to-gas mass ratio, and (3) a dynamical mass estimate, we find that the molecular gas mass (M
mol) is (0.05–11) × 1010
M
⊙. This value is consistent with the upper limit inferred from the nondetection of mid-J CO and [C i](2−1). Despite the large uncertainty in M
mol, we estimate a molecular gas-to-stellar mass ratio (μ
gas) of 0.65–140 and a gas depletion time (τ
dep) of 2.5–550 Myr; these values are broadly consistent with those of other high-redshift galaxies. B14-65666 could be an ancestor of a passive galaxy at z ≳ 4 if no gas is fueled from outside the galaxy.

BACKGROUND: Health problems with cardiovascular system disorders including congestive heart failure (CHF) still rank highly. CHF is one of the heart diseases that continue to increase in incidence and prevalence every year, including in Indonesia. Lack of health education about how home care is a factor increases the incidence of rehospitalization in CHF patients. Here, researchers have provided knowledge to patients about how things to avoid, foods to avoid, recommended foods, and diet to do.
OBJECTIVE: This study aimed to analyze effectiveness of health management education for CHF patients in Surabaya.
METHODS: The research method used is quantitative analytics with a pre-experimental design with an approach (one group pre-post-test design). The population in this study was all CHF patients admitted to hospitals in Surabaya as many as 150 respondents. Sampling using accidental sampling technique. Data were analyzed using and Wilcoxon test.
RESULTS: Wilcoxon test results obtained knowledge (p = 0.000), diet (p = 0.001), and physical activity (p = 0.001) which means there is an influence on providing health management education for CHF patients.
CONCLUSION: Health management education effectiveness for CHF patients in Surabaya. Health-care providers can add health education programs for patients with CHF or other diseases, as a form of nursing service implementation.

Full four-dimensional change analysis of topographic point cloud time series using Kalman filtering
Authors: Winiwarter Lukas , Anders Katharina , Czerwonka-Schröder Daniel , Höfle Bernhard 
Published: July 2023

Abstract. Four-dimensional (4D) topographic point clouds contain information on surface change processes and their spatial and temporal characteristics, such as the duration, location, and extent of mass movements. To automatically extract and analyze changes and patterns in surface activity from this data, methods considering the spatial and temporal properties are required. The commonly used model-to-model cloud comparison (M3C2) point cloud distance reduces uncertainty through spatial averaging for bitemporal analysis. To extend this concept into the full spatiotemporal domain, we use a Kalman filter for change analysis in point cloud time series. The filter incorporates M3C2 distances together with uncertainties obtained through error propagation as Bayesian priors in a dynamic model. The Kalman filter yields a smoothed estimate of the change time series for each spatial location in the scene, again associated with an uncertainty. Through the temporal smoothing, the Kalman filter uncertainty is generally lower than the individual bitemporal uncertainties, which therefore allows the detection of more changes as significant. We apply our method to a dataset of tri-hourly terrestrial laser scanning point clouds of around 90 d (674 epochs) showcasing a debris-covered high-mountain slope affected by gravitational mass movements and snow cover dynamics in Tyrol, Austria. The method enables us to almost double the number of points where change is detected as significant (from 24 % to 47 % of the area of interest) compared to bitemporal M3C2 with error propagation. Since the Kalman filter interpolates the time series, the estimated change values can be temporally resampled. This provides a solution for subsequent analysis methods that are unable to deal with missing data, as may be caused by, e.g., foggy or rainy weather conditions or temporary occlusion. Furthermore, noise in the time series is reduced by the spatiotemporal filter. By comparison to the raw time series and temporal median smoothing, we highlight the main advantage of our method, which is the extraction of a smoothed best estimate time series for change and associated uncertainty at each location. A drawback of the Kalman filter is that it is ill-suited to accurately model discrete events of large magnitude. It excels, however, at detecting gradual or continuous changes at small magnitudes. In conclusion, the combined consideration of temporal and spatial information in the data enables a notable reduction in the associated uncertainty in quantified change values for each point in space and time, in turn allowing the extraction of more information from the 4D point cloud dataset.
The role of boundary layer processes in summer-time Arctic cyclones
Authors: Croad Hannah L. , Methven John , Harvey Ben , Keeley Sarah P. E. , Volonté Ambrogio 
Published: July 2023

Abstract. Arctic cyclones are the most energetic weather systems in the Arctic, producing strong winds and precipitation that present major weather hazards. In summer, when the sea ice cover is reduced and more mobile, Arctic cyclones can have large impacts on ocean waves and sea ice. While the development of mid-latitude cyclones is known to be dependent on boundary layer (BL) turbulent fluxes, the dynamics of summer-time Arctic cyclones and their dependence on surface exchange processes have not been investigated. The purpose of this study is to characterise the BL processes acting in summer-time Arctic cyclones and understand their influence on cyclone evolution. The study focuses on two cyclone case studies, each characterised by a different structure during growth in the Arctic: (A) low-level-dominant vorticity (warm-core) structure and (B) upper-level-dominant vorticity (cold-core) structure, linked with a tropopause polar vortex. A potential vorticity (PV) framework is used to diagnose the BL processes in model runs from the ECMWF Integrated Forecasting System model. Both cyclones are associated with frictional Ekman pumping and downward sensible heat fluxes over sea ice. However, a third process, the frictional baroclinic generation of PV, acts differently in A and B due to differences in their low-level temperature structures. Positive PV is generated in Cyclone A near the bent-back warm front, like in typical mid-latitude cyclones. However, the same process produces negative PV tendencies in B, shown to be a consequence of the vertically aligned axisymmetric cold-core structure. This frictional process also acts to cool the lower troposphere, reducing the warm-core anomaly in A and amplifying the cold-core anomaly in B. Both cyclones attain a vertically aligned cold-core structure that persists for several days after maximum intensity, which is consistent with cooling from frictional Ekman pumping, frictional baroclinic PV generation, and downward sensible heat fluxes. This may help to explain the longevity of isolated cold-core Arctic cyclones with columnar vorticity structure.

Féminités scandaleuses : Delphine de Germaine de Staël et Le Deuxième sexe de Simone de Beauvoir
Authors: Genand Stéphanie 
Published: July 2023

Quel est le lien entre l’hystérisation et l’utérus ? Pourquoi la question féminine déchaîne-t-elle toujours des résistances et des passions qui paralysent le débat ? Deux ouvrages en témoignent : Delphine de Germaine de Staël (1802) et Le Deuxième sexe de Simone de Beauvoir (1949). Leur réception hostile, ajoutée au fait que les autrices soient des femmes et que leurs textes mettent en lumière le problème moral et social de la liberté féminine (divorce, sexualité) déclenche le ressentiment. Staël et Beauvoir sont-elles même encore des femmes pour se détacher ainsi de leur condition ?
Cormenin et l’hystérisation de la joute parlementaire sous la monarchie de Juillet
Authors: Saintes Laetitia 
Published: July 2023

Sous la monarchie de Juillet, le débat parlementaire se démarque par la violence verbale parfois inouïe des échanges que Louis de Cormenin, député et pamphlétaire, décrit dans son Livre des orateurs (1836). Face à cette hystérisation du débat parlementaire, Cormenin prône-t-il la modération ? Revendique-t-il plutôt un débat laissant latitude à la violence verbale contre l’immobilisme de la politique ministérielle ? Ou prône-t-il une voie médiane ? C’est ce que cette contribution s’emploie à déterminer à la lumière du Livre des orateurs et des Lettres sur la liste civile.
L’affaire Dreyfus, laboratoire de l’infox

Cet article analyse le mécanisme des fake news (ou de l’infox) en prenant l’exemple des polémiques de l’affaire Dreyfus. Après avoir rappelé certaines des légendes qui ont occupé les médias, il montre le rôle joué par les porte-parole du camp nationaliste dans l’élaboration de fausses informations visant à soutenir la thèse de la culpabilité d’Alfred Dreyfus. Les lecteurs des journaux ont accepté ces constructions imaginaires, tandis que l’intervention de Zola a plaidé en faveur d’une distance critique en dénonçant le « virus de l’information à outrance ».
