The article considers the issue of teaching English grammar to children of secondary school age with the help of the educational platform “Vznaniya”. The search for effective means and methods of teaching a foreign language grammar remains an actual problem of modern methods of teaching foreign languages, in particular, in the context of Web 2.0 services introduction into the learning process. The article reveals the main theoretical aspects of teaching foreign language grammar; describes the main stages of working with active grammatical material. The authors substantiate the relevance of using the “Vznaniya” platform with children of secondary school age, since the platform makes it possible to take into account individual needs and the pace of learning in adolescence, when children have a reduced overall motivation to study, making the learning process of such a traditionally “boring” aspect of language as grammar more interesting due to the elements of gamification. The authors of the article cite statistical data from their survey of English language teachers in schools, which determine the current state of the problem of teaching grammar using the "Vznaniya" platform. The article provides the basic theoretical aspects of teaching English grammar; analyzes the functionality of the Russian educational platform “Vznaniya”. The article also gives the description of the stages of teaching active grammatical material and provides examples of exercises on the “Vznaniya” platform for each of these stages. The authors also present the results of testing the set of exercises developed by them to teach English grammar to children of secondary school age using the educational platform “Vznaniya” and conclude about the advantages of teaching grammar using this platform, if certain pedagogical conditions are met.

This article presents the analysis of the experience of implementation of the course “Service-Learning” in an educational organization. Service-learning implies that students, while studying and applying their professional skills, benefit society in solving social problems. This paper proposes a comprehensive, interdisciplinary approach consisting of a combination of socio-philosophical reflection with pedagogical and cultural aspects, which allows us to highlight the problem from various angles. The focus is on the value-worldview transformations of the personality. The novelty of the paper is the study of the socio-cultural significance of the “Service-Learning” program. Service-learning in this context declares itself as an innovative educational program capable of acting as a prototype of a new paradigm of higher education, focused not on narrow professionalization, but on the comprehensive development of a person in the unity of his cognitive, emotional and behavioral aspects. The socio-philosophical understanding of the narratives of the course can contribute to the formation of an approach focused on the comprehensive development of personality. As a result of the research, the conceptual foundations of the course aimed at service-learning, its value and worldview attitudes are revealed. The correspondence of the course content to the tasks of spiritual and moral development of the individual is evaluated. The personal transformations of students during the course are investigated.

Abstract
We present the full Hubble diagram of photometrically classified Type Ia supernovae (SNe Ia) from the Dark Energy Survey supernova program (DES-SN). DES-SN discovered more than 20,000 SN candidates and obtained spectroscopic redshifts of 7000 host galaxies. Based on the light-curve quality, we select 1635 photometrically identified SNe Ia with spectroscopic redshift 0.10 < z < 1.13, which is the largest sample of supernovae from any single survey and increases the number of known z > 0.5 supernovae by a factor of 5. In a companion paper, we present cosmological results of the DES-SN sample combined with 194 spectroscopically classified SNe Ia at low redshift as an anchor for cosmological fits. Here we present extensive modeling of this combined sample and validate the entire analysis pipeline used to derive distances. We show that the statistical and systematic uncertainties on cosmological parameters are

Combining the DES SN data with the highly complementary cosmic microwave background measurements by Planck Collaboration reduces by a factor of 4 uncertainties on cosmological parameters. In all cases, statistical uncertainties dominate over systematics. We show that uncertainties due to photometric classification make up less than 10% of the total systematic uncertainty budget. This result sets the stage for the next generation of SN cosmology surveys such as the Vera C. Rubin Observatory's Legacy Survey of Space and Time.
Boundary Layers of Circumplanetary Disks around Spinning Planets. II. Global Modes with Azimuthal Magnetic Fields
Authors: Fu 付 Zhihao 智豪 , Huang 黄 Shunquan 顺权 , Yu 余 Cong 聪 
Published: October 2024

Abstract
The accretion of material from disks onto weakly magnetized objects invariably involves its traversal through a material surface, known as the boundary layer (BL). Our prior studies have revealed two distinct global wave modes for circumplanetary disks with BLs exhibiting opposite behaviors in spin modulation. We perform a detailed analysis of the effects of magnetic fields on these global modes, highlighting how magnetic resonances and turning points could complicate the wave dynamics. The angular momentum flux becomes positive near the BL with increasing magnetic field strength. We also examine the perturbation profile to demonstrate the amplification of magnetic fields within the BL. The dependence of growth rates on the magnetic field strength and the spin rate are systematically investigated. We find that stronger magnetic fields tend to result in lower terminal spin rates. We stress the potential possibility of the formation of angular momentum belts and pressure bumps. The implications for the spin evolution and quasiperiodic oscillations observed in compact objects are also briefly discussed. Our calculations advance the understanding of magnetohydrodynamical accretion processes and lay a foundation for observational studies and numerical simulations.

Abstract
We report 10 fast radio bursts (FRBs) detected in the far sidelobe region (i.e., ≥5° off-meridian) of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) from August 28 2018 to August 31 2021. We localize the bursts by fitting their spectra with a model of the CHIME/FRB synthesized beam response. We find that the far sidelobe events have on average ∼500 times greater fluxes than events detected in CHIME’s main lobe. We show that the sidelobe sample is therefore statistically ∼20 times closer than the main lobe sample. We find promising host galaxy candidates (P
cc < 1%) for two of the FRBs, 20190112B and 20210310B, at distances of 38 and 16 Mpc, respectively. CHIME/FRB did not observe repetition of similar brightness from the uniform sample of 10 sidelobe FRBs in a total exposure time of 35,580 hr. Under the assumption of Poisson-distributed bursts, we infer that the mean repetition interval above the detection threshold of the far sidelobe events is longer than 11,880 hr, which is at least 2380 times larger than the interval from known CHIME/FRB detected repeating sources, with some caveats, notably that very narrowband events could have been missed. Our results from these far sidelobe events suggest one of two scenarios: either (1) all FRBs repeat and the repetition intervals span a wide range, with high-rate repeaters being a rare sub-population, or (2) non-repeating FRBs are a distinct population different from known repeaters.
Lyman Limit System with O vi in the Circumgalactic Environment of a Pair of Galaxies

Published: October 2024

Abstract
We report on the analysis of a multiphase Lyman limit system (LLS) at z = 0.39047 identified toward the background quasar FBQS J0209–0438. The O VI doublet lines associated with this absorber have a different profile from the low-ionization metals and H i. Ly α has a very broad H i (b ≈ 150 km s−1) component well-aligned with one of the O VI components. The Doppler b-parameters for the broad H i and O VI indicate gas with T = (0.8 − 2.0) × 106 K and a total hydrogen column density that is an order of magnitude larger than the cooler phase of gas responsible for the LLS. Observations by the Very Large Telescope MUSE show two moderately star-forming galaxies within ρ ≲ 105 kpc and ∣Δv∣ ≲ 130 km s−1 of the absorber, one of them a dwarf galaxy (M

⊙, and the dwarf galaxy within its virial radius. Although the absorption is aligned with the extended major axis of the larger galaxy, the line-of-sight velocity of the absorbing gas is inconsistent with corotating accretion. The metallicity inferred for the LLS is lower than the gas phase [O/H] of the two galaxies. The mixture of cool and warm/hot gas phases for the absorbing gas and its proximity and orientation to the galaxy pair points to the LLS being a high-velocity gas in the combined halo environment of both galaxies.
Are There Local Dynamos Acting in Sunspot Regions?
Authors: Jin Chunlan , Zhou Guiping , Ji Haisheng , Wang Jingxiu 
Published: October 2024

Abstract
In solar physics, a long-unanswered question is whether or not there are local dynamos acting in sunspot regions. Here we report an observed pattern of magnetic evolution that makes the sunspots alive with ample complexity and energy. This anomalous pattern manifests as peculiar bipolar magnetic emergences (BMEs), exhibiting the following characteristics: (1) the BMEs persistently appear beyond the penumbra, encircling the sunspot in an end-to-end configuration; (2) each BME gradually grows and separates its two polarities along an arc trajectory centered on the sunspot; (3) a circular brightening belt is manifested in the ultraviolet/extreme-ultraviolet radiations during the BMEs’ evolution; and (4) the sunspot regions with such an evolution pattern often exhibit vigorous solar activity, such as homogeneous major flares. The magnetic evolving pattern and relevant flare activity indicate the presence of a local dynamo, and we characterize it as a twisting-reconnecting dynamo.

Abstract
We present the results obtained from timing and spectral studies of 15 thermonuclear X-ray bursts from 4U 1820–30 observed with the Neutron Star Interior Composition Explorer (NICER) during its 5 yr of observations between 2017 and 2022. All bursts showed clear signs of photospheric radius expansion (PRE), where the neutron star (NS) photosphere expanded more than 50 km above the surface. One of the bursts produced a superexpansion with a blackbody emission radius of 902 km for the first time with NICER. We searched for burst oscillations in all 15 bursts and found evidence of a coherent oscillation at 716 Hz in a burst, with a 2.9σ detection level based on Monte Carlo simulations. If confirmed with future observations, 4U 1820–30 would become the fastest-spinning NS known in X-ray binary systems. The fractional rms amplitude of the candidate burst oscillation was found to be 5.8% in the energy range of 3–10 keV. Following the variable persistent model from burst time-resolved spectroscopy, an anticorrelation is seen between the maximum scaling factor value and the (preburst) persistent flux. We detected a low value of ionization at the peak of each burst based on reflection modeling of burst spectra. A partially interacting inner accretion disk or a weakly ionized outer disk may cause the observed ionization dip during the PRE phase.
Cosmic Ray Diffusion in Magnetic Fields Amplified by Nonlinear Turbulent Dynamo
Authors: Zhang Chao , Xu Siyao 
Published: October 2024

Abstract
The diffusion of cosmic rays (CRs) in turbulent magnetic fields is fundamental to understanding various astrophysical processes. We explore the CR diffusion in the magnetic fluctuations amplified by the nonlinear turbulent dynamo in the absence of a strong mean magnetic field. Using test particle simulations, we identify three distinct CR diffusion regimes: mirroring, wandering, and magnetic moment scattering (MMS). With highly inhomogeneous distribution of the dynamo-amplified magnetic fields, we find that the diffusion of CRs is also spatially inhomogeneous. Our results reveal that lower-energy CRs preferentially undergo the mirror and wandering diffusion in the strong-field regions, and the MMS diffusion in the weak-field regions. The former two diffusion mechanisms play a more important role toward lower CR energies, resulting in a relatively weak energy dependence of the overall CR mean free path (MFP). In contrast, higher-energy CRs predominantly undergo the MMS diffusion, for which the incomplete particle gyration, i.e., the limit case of mirroring, in strong fields has a more significant effect than the scattering by small-scale field tangling/reversal. Compared with lower-energy CRs, they are more poorly confined in space and their MFPs have a stronger energy dependence. We stress the fundamental role of magnetic field inhomogeneity of nonlinear turbulent dynamo in causing the different diffusion behavior of CRs compared to that in sub-Alfvénic magnetohydrodynamic turbulence.

Abstract
We report a spectroscopic observation of comet C/2023 A3 using an 80 mm apochromatic refractor equipped with a custom-built spectrometer with a resolution of R ∼ 2500 on the night of 2024 October 4. Sodium D lines were detected prominently, while no other emission lines, particularly carbon-bearing species, were observed, which suggests that comet C/2023 A3 may be carbon-depleted. The mobility and flexibility of our observational setup highlight the value of amateur telescopes in observing low-altitude targets like C/2023 A3 as a complement to professional facilities.
Le non-recours à la formation continue en entreprise
Authors: Lescure Emmanuel de 
Published: October 2024

Cet article s’attache à montrer que, bien que forgée dans le cadre de la lutte contre la pauvreté, la notion de non-recours est pertinente pour appréhender les rapports des salarié·es à la formation en entreprise. Alors que les réformes successives du droit de la formation tendent à en faire un droit individuel, elle n’est pas uniformément perçue comme un bien universel. Proposant une première mesure du phénomène, l’article montre qu’il concerne une part non négligeable de la population et identifie une variété de profils, contrastés et hétérogènes, dont il étudie les rapports à la formation. Ce faisant, il invite à la prise en compte d’un élément laissé dans l’ombre, l’existence d’une « non-demande » de formation qui caractérise certains profils.
