Abstract
We investigate protoneutron star (PNS) convection using our newly developed general relativistic Boltzmann neutrino radiation hydrodynamics code. This is a pilot study for more comprehensive investigations later. As such, we take a snapshot of a PNS at 2.3 s after bounce from a 1D PNS cooling calculation and run our simulation for ∼160 ms in 2D under axisymmetry. The original PNS cooling calculation neglected convection entirely and the initial conditions were linearly unstable to convection. We find in our 2D simulation that convection is instigated there indeed and expands inward after being full-fledged. The convection then settled to a quasi-steady state after ∼100 ms, being sustained by the negative Y

e
gradient, which is in turn maintained by neutrino emissions. It enhances the luminosities and mean energies of all species of neutrinos compared to 1D. Taking advantage of the Boltzmann solver, we analyse the possible occurrence of neutrino fast flavor conversion (FFC). We found that FFC is likely to occur in regions where Y

e
is lower, and that the growth rate can be as high as ∼10−1 cm−1.
Prospects for 21 cm Galaxy Cross-correlations with HERA and the Roman High-latitude Survey

Published: February 2023

Abstract
The cross-correlation between the 21 cm field and the galaxy distribution is a potential probe of the Epoch of Reionization (EoR). The 21 cm signal traces neutral gas in the intergalactic medium and, on large spatial scales, this should be anticorrelated with the high-redshift galaxy distribution, which partly sources and tracks the ionized gas. In the near future, interferometers such as the Hydrogen Epoch of Reionization Array (HERA) are projected to provide extremely sensitive measurements of the 21 cm power spectrum. At the same time, the Nancy Grace Roman Space Telescope (Roman) will produce the most extensive catalog to date of bright galaxies from the EoR. Using seminumeric simulations of reionization, we explore the prospects for measuring the cross-power spectrum between the 21 cm and galaxy fields during the EoR. We forecast a 12σ detection between HERA and Roman, assuming an overlapping survey area of 500 deg2, redshift uncertainties of σ

z
= 0.01 (as expected for the high-latitude spectroscopic survey of Lyα-emitting galaxies), and an effective Lyα emitter duty cycle of f
LAE = 0.1. Thus the HERA–Roman cross-power spectrum may be used to help verify 21 cm detections from HERA. We find that the shot-noise in the galaxy distribution is a limiting factor for detection, and so supplemental observations using Roman should prioritize deeper observations, rather than covering a wider field of view. We have made a public GitHub repository containing key parts of the calculation, which accompanies this paper: https://github.com/plaplant/21cm_gal_cross_correlation.
The GMRT High Resolution Southern Sky Survey for Pulsars and Transients. IV. Discovery of Four New Pulsars with an FFA Search

Published: February 2023

Abstract
The fast Fourier transform (FFT) based periodicity search methods provide an efficient way to search for millisecond and binary pulsars but encounter significant sensitivity degradation while searching for long period and short duty cycle pulsars. An alternative to FFT-based search methods called the fast folding algorithm (FFA) search provides superior sensitivity to search for signals with long periods and short duty cycles. In the GMRT High Resolution Southern Sky (GHRSS) survey, we are using an FFA-based pipeline to search for isolated pulsars in a period range of 100 ms to 100 s. We have processed 2800 degree2 of the sky coverage away from the Galactic plane and discovered six new pulsars. Here, we report the discovery of four of these pulsars with the FFA search pipeline. This includes a narrow duty cycle pulsar, J1936−30, which shows nulling behavior with an extreme nulling fraction of ∼90%. Two of the GHRSS discoveries from the FFA search lie in narrow duty cycle ranges beyond the limit of the existing population. The implementation of FFA search in the GHRSS survey and other pulsar surveys is expected to recover the missing population of long period and short duty cycle pulsars.
Probing the Stellar Wind of the Wolf–Rayet Star in IC 10 X-1

Abstract
IC 10 X-1 is an eclipsing high-mass X-ray binary containing a stellar-mass black hole (BH) and a Wolf–Rayet (WR) donor star with an orbital period of P = 34.9 hr. This binary belongs to a group of systems that can be the progenitors of gravitational-wave sources; hence understanding the dynamics of systems such as IC 10 X-1 is of paramount importance. The prominent He ii 4686 emission line (previously used in mass estimates of the BH) is out of phase with the X-ray eclipse, suggesting that this line originates somewhere in the ionized wind of the WR star or in the accretion disk. We obtained 52 spectra from the GEMINI/GMOS archive, observed between 2001 and 2019. We analyzed the spectra both individually, and after binning them by orbital phase to improve the signal-to-noise ratio. The radial-velocity curve from the stacked data is similar to historical results, indicating the overall parameters of the binary have remained constant. However, the He ii line profile shows a correlation with the X-ray hardness-ratio values; also, we report a pronounced skewness of the line profile, and the skewness varies with orbital phase. These results support a paradigm wherein the He ii line tracks structures in the stellar wind that are produced by interactions with the BH’s ionizing radiation and the accretion flow. We compare the observable signatures of two alternative hypotheses proposed in the literature: wind irradiation plus shadowing, and accretion disk hotspot; and we explore how the line-profile variations fit into each of these models.
An 8.0% Determination of the Baryon Fraction in the Intergalactic Medium from Localized Fast Radio Bursts
Authors: Wang Bao , Wei Jun-Jie 
Published: February 2023

Abstract
The dispersion measure (DM)–redshift relation of fast radio bursts (FRBs) has been proposed as a potential new tool for probing the intergalactic medium (IGM) and for studying cosmology. However, poor knowledge of the baryon fraction in the IGM (f
IGM) and its degeneracy with cosmological parameters impose restrictions on the cosmological applications of FRBs. Furthermore, DMs contributed by the IGM (DMIGM) and host galaxy (DMhost), important cosmological quantities, cannot be exactly extracted from observations, which would bring uncontrolled systematic uncertainties in FRB cosmology. In this work, we use 17 localized FRBs to constrain f
IGM and its possible redshift evolution. Other cosmological probes such as type Ia supernovae, baryon acoustic oscillations, and cosmic microwave background radiation are combined to break parameter degeneracy. Taking into account the probability distributions of DMIGM and DMhost derived from the IllustrisTNG simulation, we obtain a robust measurement of f
IGM = 0.927 ± 0.075, representing a precision of 8.0%. We find that there is no strong evidence for the redshift dependence of f
IGM at the current observational data level. The rapid progress in localizing FRBs will significantly improve the constraints on f
IGM.
The [S ii] Spectral Images of the Planetary Nebula NGC 7009. II. Major Axis

Published: February 2023

Abstract
We derived position–velocity density distribution diagrams along the major (PA = 77°) axis of the elliptical planetary nebula NGC 7009 with the Keck HIRES [S ii] 6716/6731 Å doublet spectral images. The average densities of the main shell and knots of NGC 7009 derived from the [S ii] 6716/6731 Å fluxes integrated over the line of sight indicate a density range of N

e
= 103.4 to 103.9 cm−3, while the local densities from the volume fraction resolved in radial velocities along the line of sight show a considerably large range of about 102.8–104.7 cm−3. The derived projection angle of the major axis of the main shell is ψ ∼ 18.3° (±2°). Assuming that the main shell is an ellipsoidal shell with a ≃ 16″ and b ≃ 6″, we found the range of the expansion velocity, radius, and latitude of four knots and a hot bubble. The four knots at points in symmetrical positions are roughly aligned with the same axis of expansion of latitudes ϕ ∼ ±34.5° (±0.6°): one pair expands at about 35 km s−1 close to the main ellipsoidal shell, and the other expands rapidly at about 60 km s−1 at a distance of r ∼ 16″. In the latitude range ϕ = 65°–75°, the hot bubble of a relatively large structure expands rapidly with a velocity of 130–150 km s−1. The four knots and hot bubble points, which expand faster than the main shell, appear to have been formed by two to three eruptions at a different epoch from the primary structure formation.
L’intégration des enjeux de la logique de parcours dans les politiques publiques en santé : une lecture au prisme des régimes de gouvernementalité
Authors: Aubert Isabelle , Kletz Frédéric , Sardas Jean-Claude 
Published: February 2023

Conçue en opposition à la logique à l’acte, la logique de parcours imprègne les réformes de l’organisation et du financement du système de santé français depuis une quinzaine d’années. Elle s’inscrit dans le prolongement des efforts menés depuis plusieurs décennies pour améliorer la continuité et la cohérence des prises en charge des patients. Notre objectif est d’analyser les évolutions de l’action publique sanitaire induites par la promotion de cette nouvelle approche, en caractérisant les éléments de continuité et de rupture par rapport à la doctrine et aux politiques publiques antérieures. Pour traiter ce sujet, nous mobilisons le cadre d’analyse foucaldien des « régimes de gouvernementalité » (Aggeri, 2005), en privilégiant l’étude des instruments déployés par les pouvoirs publics (Lascoumes et Simard, 2011). Nous souhaitons montrer comment les politiques publiques sanitaires se cristallisent historiquement dans des régimes successifs, articulant le couplage entre une rationalité dominante et une instrumentation, et comment la logique de parcours s’inscrit dans ce mouvement. Notre méthodologie est qualitative, et s’appuie sur une étude longitudinale des politiques publiques sanitaires (Langley et al. , 2013) et une étude de cas (Yin, 2014) sur le déploiement par une Agence Régionale de Santé d’un outil numérique de coordination entre professionnels. Nos résultats mettent en lumière la succession historique de quatre régimes de gouvernementalité sanitaire, dont nous définissons les caractéristiques, ainsi que l’incomplétude et l’incohérence partielle du régime actuel, sous-tendu par la logique de parcours.
Évaluation des politiques publiques : vers une pratique intégrée au pilotage de l’action publique
Authors: Goter Françoise , Khenniche Samia 
Published: February 2023

L’évaluation des politiques publiques en France est soumise à un paradoxe : louée par l’ensemble des parties prenantes de l’action publique, elle n’est que faiblement pratiquée ; lorsqu’elle est pratiquée, elle n’alimente que peu le pilotage de l’action publique. À partir d’une recherche-intervention longitudinale réalisée de 2018 à 2020 concernant le dispositif public Atelier Santé Ville d’une métropole française, cet article s’interroge sur les apports d’une démarche d’évaluation articulée au pilotage de la performance et intégrant les parties prenantes. Après avoir mis en évidence les résultats de l’évaluation des impacts socio-économiques de ce dispositif public, nous proposons les caractéristiques de ce que pourrait être une évaluation participative et intégrée au pilotage de l’action publique.
Evaluation of the Effects of Myopic Astigmatism Correction and Anterior Corneal Curvature on Functional Optical Zone After SMILE
Authors: Wang Xueqing , Xia Likun 
Published: February 2023

Purpose:
To evaluate the influence of different degrees of myopic astigmatism correction and preoperative anterior corneal curvature on the functional optical zone (FOZ) following small incision lenticule extraction (SMILE).

Methods:
In this retrospective study, 68 patients (106 eyes) treated with SMILE were grouped according to myopic astigmatism correction: control (0.00 diopters [D]), moderate astigmatism (−0.50 to −2.00 D), and high astigmatism (> −2.00 D). The FOZ was measured and compared between the three groups for 3 months. Correlations between attempted correction, anterior corneal curvature, corneal aberrations, and the FOZ were analyzed.

Results:

The preoperative mean treatment spherical equivalent was comparable among the three groups. The average FOZ was 5.06 ± 0.24 mm in the control group, 5.19 ± 0.25 mm in the moderate astigmatism group, and 5.35 ± 0.20 mm in the high astigmatism group The FOZ showed statistically significant differences among the three groups (
P
< .001), particularly between the high astigmatism group and the other two groups (
P
< .001 and .018). Correlation analysis showed that the total higher order aberrations, coma, and spherical aberration change were correlated with the FOZ (
P
< .001). Preoperative steep keratometry, average keratometry, and corneal astigmatism were significantly correlated with the FOZ (
P
< .05). The correlation remained after excluding the influence of attempted correction on the FOZ (
P
< .05). After adjusting for other risk factors using multiple linear regression analysis, there was still a significant positive association between preoperative steep keratometry and the FOZ (
P
< .001).

Conclusions:
Patients with higher myopic astigmatism achieved a larger FOZ and less induced horizontal coma than the control and moderate astigmatism groups. A larger FOZ after SMILE can be achieved in eyes with steeper keratometry.

Evidence that High-Affinity IgE Can Develop in the Germinal Center in the Absence of an IgG1-Switched Intermediate
Authors: Chen Qiang , Liu Hong , Luling Noelle , Reinke Julia , Dent Alexander L 
Published: February 2023

Abstract
High-affinity allergen-specific IgE is essential for the severe allergic anaphylaxis response. High-affinity Abs are formed by successive rounds of selection of Ag-specific B cells in the germinal center (GC); however, several studies have shown that IgE+ GC B cells are impaired in their ability to undergo selection in the GC. A pathway, known as the “indirect switching pathway” for IgE, has been described whereby Ag-specific B cells initially switch to the IgG1 isotype and undergo affinity selection in the GC, with a secondary switch to the IgE isotype after affinity selection. In previous work, using a food allergy model in mice, we investigated how high-affinity IgE develops in the GC, but we did not test the indirect switching model. In this study, we analyzed the importance of the indirect switching pathway by constructing IgG1-cre Bcl6-fl/fl mice. In these mice, once B cells switch to IgG1, they delete Bcl6 and thus cannot enter or persist in the GC. When we tested IgG1-cre Bcl6-fl/fl mice with our food allergy model, we found that, as expected, IgG1 Abs had decreased affinity, but unexpectedly, the affinity of IgE for allergen was unchanged. IgG1-cre Bcl6-fl/fl mice underwent anaphylaxis in response to allergen, consistent with the formation of high-affinity IgE. Thus, in a food allergy response, high-affinity IgE can be efficiently formed in the absence of indirect switching to IgG1, either by direct selection of IgE+ GC B cells or indirect selection of IgM+ GC B cells that later switch to IgE.
Towards a postmissionary review of mission station names in the Church of Christ in Zimbabwe
Authors: Masengwe Gift , Dube Bekithemba 
Published: February 2023

Christian missions are historically captured in the construction of mission stations that facilitated religious instruction to advance the gospel with unintended consequences, such as an extension of missionary-colonial ideologies and attitudes. This article discusses how these were captured in mission station naming, inclusive of erroneous or misspelt names. This makes it necessary for the Church of Christ in Zimbabwe’s (COCZ) rural membership, commonly around mission stations, to rename these centres. The distortion of history on mission stations like Dadaya calls for the renaming of the station so as to recover lost values and culture, and the significance of the ecology to Africans. Our discovery of Dadaya macrops, an Asiatic marine species of water flea found in freshwater in this study, denies the assumption that Dadaya was a misspelling of Dayataya. This makes us assume that Dadaya was an idolatrous symbol for missionaries that rhymed with local isotopes to mentally drawn local communities. Norming the mission station, missionaries named Dadaya to transmit images, symbols and meanings known to New Zealand supporting churches. Dayataya Hills has been used as a scapegoat to validate their Dadaya macrops symbol. This study probes into the need to correct and guide people in renaming the mission station. Renaming transforms Dadaya into an African mission station. The article used critical discourse analysis (CDA) from purposive snowball interview results and a hermeneutic of suspicion to probe into naming the mission station.Contribution: The article is interdisciplinary involving missionary history, humanity, socialisation, missiology, literature and education. it contributes to knowledge through decentering on African discourses, contextualisation, christianisation and decolonised church of christ positioned for healing and transformation where church names are not used for perpetuate Westernisation in African context.
Epidemiological, Clinical, and Histopathological Characteristics of Patients with Sporotrichoid Lymphocutaneous Infection in Southern Thailand: A 10-Year Retrospective Study
Authors: Wongrat Tanapong , Aiempanakit Kumpol , Kanchanasuwan Siripen 
Published: February 2023

ABSTRACT.
Sporotrichoid lymphocutaneous infection is caused by a variety of pathogens. However, in most cases, the causative pathogen cannot be identified on the basis of clinical and histopathological features. We examined the clinical manifestations, histopathologic findings, causative pathogens, treatment, and prognostic factors of sporotrichoid lymphocutaneous infection, specifically in the context of Thailand. The electronic medical records of patients with sporotrichoid lymphocutaneous infection who visited Songklanagarind Hospital from January 2000 to December 2010 were reviewed. A total of 53 patients were included; 41 (77.4%) were female, 12 (22.6%) were male, and the mean (SD) age was 52.9 (± 15.9) years. Nodules, plaques, and papules were the most commonly observed morphologies. Upper extremities were the most commonly infected sites. Mammal-caused injuries were associated with fungal infection but not at a statistically significant level. The most common histopathologic finding was suppurative granuloma. The identified causative pathogens were mainly dematiaceous fungus and occasionally nontuberculous Mycobacterium. Itraconazole was the medication of choice for empiric and specific treatment of the patients with confirmed fungal infection. Dematiaceous fungi were the most common identified pathogens causing sporotrichoid lymphocutaneous infection in southern Thailand. Empirical itraconazole is useful, especially in patients who report contact injury caused by pets at the primary lesion site. Skin biopsy for tissue histopathology and culture is essential.

ABSTRACT.
Maternal malaria and infections during pregnancy are risk factors for fetal growth restriction. We assessed the impact of preventive treatment in pregnancy on maternal malaria and fetal growth. Between 2003 and 2006, we enrolled 1,320 pregnant Malawian women, 14–26 gestation weeks, in a randomized trial and treated them with two doses of sulfadoxine-pyrimethamine (SP, control) at enrollment and between 28–34 gestation weeks; with monthly SP from enrollment until 37 gestation weeks; or with monthly SP and azithromycin twice, at enrollment and between 28 and 34 gestation weeks (AZI-SP). Participants were seen at 4-week intervals until 36 completed gestation weeks and weekly thereafter. At each visit, we collected dried blood spots for real-time polymerase chain reaction diagnosing of malaria parasitemia and, in a random subgroup of 341 women, we measured fetal biparietal diameter and femur length with ultrasound. For the monthly SP versus the control group, the odds ratios (OR) (95% CI) of malaria parasitemia during the second, third, and both trimesters combined were 0.79 (0.46–1.37), 0.58 (0.37–0.92), and 0.64 (0.42–0.98), respectively. The corresponding ORs for the AZI-SP versus control group were 0.47 (0.26–0.84), 0.51 (0.32–0.81), and 0.50 (0.32–0.76), respectively. Differences between the AZI-SP and the monthly SP groups were not statistically significant. The interventions did not affect fetal biparietal diameter and femur length growth velocity. The results suggest that preventive maternal treatment with monthly SP reduced malaria parasitemia during pregnancy in Malawi and that the addition of azithromycin did not provide much additional antimalarial effect.
Cuba y la nueva “marea rosa”
Authors: Mongan Marco Matías 
Published: February 2023

En los últimos cinco años América Latina ha evidenciado un paulatino giro a la izquierda, lo que ha llevado a que algunos analistas como Jorge Castañeda (2021) y Andrés Oppenheimer (2022) ya hablen sobre una nueva “marea rosa” en la región. El nuevo contexto político regional ha llevado a que el gobierno de Miguel Díaz-Canel se ilusione con la posibilidad de que Cuba recupere los niveles de autonomía que disfrutó durante el denominado “regionalismo post-liberal” (2003-2015). En este marco, el presente artículo se propone: 1) identificar las nuevas oportunidades de inserción internacional que se abren para Cuba en esta nueva etapa y 2) analizar en qué medida la nueva “marea rosa” puede contribuir a que el país recupere los niveles de autonomía que disfrutó durante el “regionalismo post-liberal” y fortalezca así su maltrecha viabilidad nacional.
