Published: December 2023

To ensure an independent assessment of the applicability, safety and effectiveness of mechanical equipment used during the survey and demining of a contaminated area, it is necessary to test and evaluate its conformity. This makes it possible to assess the capabilities and potential of new technologies and confirm the performance and operational characteristics of the equipment used. To implement the above, it is necessary to clearly define the requirements that mechanical equipment in the field of humanitarian demining must meet; regulatory documents for which testing and conformity assessment must be carried out, i.e., a methodological apparatus for testing and assessing mechanical equipment and tools for it must be developed.
The results of the analysis of scientific publications indicate that the issue of determining the requirements for mechanical equipment for humanitarian demining has not been studied, and there is no methodological apparatus for assessing the conformity of equipment and conducting tests.
The purpose of the article is to investigate the international and regional experience of humanitarian demining in the context of regulatory and methodological support for determining the requirements for mechanical equipment and methods for their confirmation, as well as the possibility of their adaptation to the national mine action system.
It has been established that the following factors should be taken into consideration when developing and using mechanical demining equipment: the specific hazard of ERW, the minimum distance from the explosion site; simplicity of design and operation; maintainability and stability of equipment in the area of operations; ability to transport to the demining site independently; adaptability of mechanical means to different terrain conditions; ability to achieve the required demining depth (15 cm) for Ukraine.
It is recommended to take into account the practical experience and regulatory framework of competent international organizations for humanitarian demining to develop a regulatory and methodological apparatus for testing and assessing the conformity of mechanical demining equipment.

THE METHOD OF ADJUSTING THE MULTI-FREQUENCY PROBING RADAR SIGNAL PARAMETERS AND THE TROPOSPHERIC RADIO WAVEGUIDE CHARACTERISTICS
Authors: Pievtsov H. , Oleschuk M. 
Published: December 2023

Peculiarities of air circulation in the coastal zone of large reservoirs (large lakes or inland seas such as the Black and Azov Seas) can lead to a significant departure from the standard spatial distribution of meteorological and, accordingly, radiophysical characteristics of air.
As a result, it is possible for regions of space with an abnormally low attenuation level of radio waves of certain frequency ranges to appear – tropospheric radio waveguides (TWG). The appearance of TWG leads to multi-beam propagation of radio waves and fluctuations of radar signals. Fluctuations of the radar signal lead to a decrease in the range of detection of aerial objects by radars. For single-frequency radar signals, it is only possible to estimate the degree of distortion and the amount of radar detection range loss. A paradoxical situation arises when, due to TWG, it is possible to increase the range of detection of aerial objects, but due to the distortion of the radar signal in TWG, the detection performance decreases. For multi-frequency signals, it is potentially possible to adjust the parameters of the radar signal with the parameters of the radar channel (in this case, the tropospheric radio waveguide).
The adjustable parameters of a multifrequency signal include: the number of frequency components; bandwidth of the frequency component; average frequency of the frequency component; signal duration; period.
The characteristics of TWG, on which the parameters of the multifrequency signal depend, include: the lower transmission frequency of TWG; the upper transmission frequency of TWG; the delay time of the rays in the TWG.
The bandwidth and beam delay values can be obtained directly by emitting and receiving a test multi- frequency pilot signal, but this method requires the presence of a reference reflector in space, which is difficult to implement in practice.
The electrophysical characteristics of the tropospheric waveguide can be determined from the data of meteorological observations. The method developed in the article allows, based on the known characteristics of the tropospheric waveguide, to determine and adjust the parameters of a multi-frequency signal, which reduces the fluctuations of the sounding signal and increases the aerial objects detection rang.

Exploring the Formation of Resistive Pseudodisks with the GPU Code Astaroth
Authors: Väisälä Miikka S. , Shang Hsien , Galli Daniele , Lizano Susana , Krasnopolsky Ruben 
Published: December 2023

Abstract
Pseudodisks are dense structures formed perpendicular to the direction of the magnetic field during the gravitational collapse of a molecular cloud core. Numerical simulations of the formation of pseudodisks are usually computationally expensive with conventional CPU codes. To demonstrate the proof of concept of a fast computing method for this numerically costly problem, we explore the GPU-powered MHD code Astaroth, a sixth-order finite difference method with low adjustable finite resistivity implemented with sink particles. The formation of pseudodisks is physically and numerically robust and can be achieved with a simple and clean setup for this newly adopted numerical approach for science verification. The method’s potential is illustrated by evidencing the dependence on the initial magnetic field strength of specific physical features accompanying the formation of pseudodisks, e.g., the occurrence of infall shocks and the variable behavior of the mass and magnetic flux accreted on the central object. As a performance test, we measure both weak and strong scaling of our implementation to find the most efficient way to use the code on a multi-GPU system. Once suitable physics and problem-specific implementations are realized, the GPU-accelerated code is an efficient option for 3D magnetized collapse problems.
The Impact of Patchy Reionization on Ultrafaint Dwarf Galaxies

Published: December 2023

Abstract
We investigate how patchy reionization affects the star formation history (SFH) and stellar metallicity of ultrafaint dwarf galaxies (UFDs). Patchy reionization refers to varying ultraviolet background strengths depending on a galaxy’s environment. Recent observations highlight the significance of this effect on UFDs, as UFDs can have different SFHs depending on their relative position with respect to their host halo during the period of reionization. However, most cosmological hydrodynamic simulations do not consider environmental factors such as patchy reionization, and the effect of reionization is typically applied homogeneously. Using a novel approach to implement patchy reionization, we show how SFHs of simulated UFDs can change. Our cosmological hydrodynamic zoom-in simulations focus on UFD analogs with M

⊙ at z = 0. We find that patchy reionization can weaken the effect of reionization by 2 orders of magnitude up to z = 3, enabling late star formation in half of the simulated UFDs, with quenching times ∼460 Myr later than those with homogeneous reionization. We also show that halo merger and mass assembly can affect the SFHs of simulated UFDs, in addition to patchy reionization. The average stellar iron-to-hydrogen ratio, [Fe/H], of the simulated UFDs with patchy reionization increases by 0.22–0.42 dex. Finally, our findings suggest that patchy reionization could be responsible for the extended SFHs of Magellanic UFDs compared to non-Magellanic UFDs.
Probing Orbital Parameters of Gamma-Ray Binaries with TeV Light Curves
Authors: Sushch Iurii , van Soelen Brian 
Published: December 2023

Abstract
Gamma-ray binaries are binary systems in which the energy flux peaks in the gamma-ray energy band. They harbor a compact object (a neutron star or a black hole) orbiting around a massive star, which provides a strong radiation field. It is believed that the gamma-ray emission from such objects can be strongly attenuated through the electron-positron pair production in gamma–gamma interactions. The importance of gamma–gamma absorption depends on the orbital phase and on the geometry of the system. In this work, we propose a method showing how the orbital parameters of gamma-ray binaries could be probed with TeV light curves that have imprinted features of gamma–gamma absorption.

Abstract
We describe the results of a new reverberation mapping program focused on the nearby Seyfert galaxy NGC 3227. Photometric and spectroscopic monitoring was carried out from 2022 December to 2023 June with the Las Cumbres Observatory network of telescopes. We detected time delays in several optical broad emission lines, with Hβ having the longest delay at

The new photoionization-based BLR modeling tool BELMAC finds general agreement with the observations when assuming the best-fit CARAMEL results; however, BELMAC prefers a thick-disk geometry and kinematics that are equally composed of rotation and inflow. Both codes infer a radially extended and flattened BLR that is not outflowing.
De l’insociabilité à la rébellion : civilité et incivilité selon Hobbes
Authors: Lepan Géraldine 
Published: December 2023

L’état de nature selon Hobbes a pour fonction de mettre en avant l’incivilité première de l’homme, dominé par des passions de peur et de rivalité, et toujours susceptible du refus des règles sociales. La remise en cause de l’anthropologie de l’homme social fonde sa philosophie de l’État et sa théorie de la souveraineté absolue. Hobbes relègue la question des mœurs et de la politesse derrière celle de la vertu d’obéissance ; il réclame des citoyens, incapables d’autodiscipline, une docilité qui manifeste aussi la fragilité de l’État.
Faire d’incivilité vertu. Figures du duc de Montausier
Authors: Grosperrin Jean-Philippe 
Published: December 2023

Exemple de rudesse voire de violence au rebours des usages de la civilité, Montausier (1610-1690) apparaît dans les anecdotes ou mémoires comme une figure transgressive de bizarrerie. Ses éloges posthumes construisent pourtant de ce personnage intempestif une autre image : courage de la vérité, vertu souveraine de sincérité, monument de l’esprit d’une ancienne noblesse. Son incivilité au bord de la folie se retourne alors en modèle empreint de nostalgie.
Quelques réflexions autour de l’incivilité érotique dans l’œuvre de Madeleine de Scudéry
Authors: Briot Frédéric 
Published: December 2023

Les apparences critiques sont trompeuses, l’œuvre de Madeleine de Scudéry n’y échappe pas. Une vraie pensée de l’amour charnel y est à l’œuvre, on trouvera donc dans ses romans des amants érotiquement civils et d’autres tout aussi érotiquement incivils. C’est que, pour la romancière, faire l’amour, tant au sens classique que contemporain, a un prix, a une valeur.
Incivilité et discours amoureux : la synthèse paradoxale de M me de Sévigné
Authors: Garroté Nicolas 
Published: December 2023

En dépit des apparences, M me de Sévigné emploie volontiers dans ses lettres à sa fille des tournures familières. Elle va même jusqu’à affirmer de manière ironique qu’elle n’aime pas M me de Grignan. En réalité, cette incivilité s’apparente à une forme de discours amoureux ; elle est pour l’épistolière une manière retorse et supérieure d’affirmer sa tendresse. À l’image de Montaigne, qui oppose dans les Essais une « amitié qui se flatte en l’âpreté et vigueur de son commerce » à une amitié « civilisée et artiste ».
« Santé Publique Orale » : contexte, enjeux et perspectives
Authors: Vergnes Jean-Noel , Azogui Sylvie 
Published: December 2023

La « santé publique orale » est une discipline qui tire sa légitimité épistémologique de la place très particulière du dentiste dans le champ de la santé. Elle agit comme une charnière entre la santé publique et les sciences odontologiques. La pertinence du développement d’une « santé publique orale » est bidirectionnelle. D’un côté, la « santé publique orale » prend la mesure des évolutions sanitaires et sociétales, des déterminants de santé générale, des enjeux climatiques et planétaires, afin d’orienter les décisions politiques, la formation, la recherche et les pratiques odontologiques dans des directions favorisant le bien commun, l’équité dans l’accès aux soins et les innovations techniques et sociales. D’un autre côté, la « santé publique orale » peut enrichir le domaine de la santé en général, en transférant les contributions diverses issues de la chirurgie dentaire et de ses spécificités historiques. Ainsi, l’indépendance de la chirurgie dentaire est à la fois un obstacle à la collaboration interdisciplinaire mais aussi un moyen de progresser grâce aux solutions nécessaires pour la transcender. Ajoutons qu’à l’heure des patients-partenaires et de la diffusion des enjeux d’équité, de diversité et d’inclusion, il est temps de considérer les représentants de patients comme faisant partie des acteurs de la « santé publique orale ».
Le volet bucco-dentaire de la réforme 100 % santé : premiers éléments descriptifs
Authors: Inquimbert Camille , Tramini Paul , Bas Anne-Charlotte 
Published: December 2023

La réforme 100 % s anté est un choc important dans les pratiques tarifaires et assurantielles en santé orale en France. L’objectif de l’étude est d’observer l’évolution de la consommation de soins dentaires et notamment prothétiques sur une période regroupant des années ante- et post-réforme. Cette étude exploratoire, soutenue par des travaux de recherche descriptifs, fournit les premiers éléments d’analyse utiles pour évaluer la réforme 100 % santé sur le volet bucco-dentaire. Il s’agit d’une étude exploratoire reposant sur les données de consommation de soins de 3 466 764 bénéficiaires de 3-25 ans de l’Assurance maladie en Occitanie, sur la période allant du 1 er janvier 2016 au 31 décembre 2020. L’analyse descriptive de ces données a permis de mettre en évidence que les soins prothétiques sont les seuls soins consommés dont la moyenne augmente entre 2019 et 2020 : hausse relative de +4 % chez les 3-25 ans et +6,7 % chez les 21-25 ans. De plus, chez les 21-25 ans, on observe un recul de la part des prothèses dans les soins consommés en 2019, puis un regain se rapprochant de 0,3 % de la part initiale en 2020. Malgré l’impossibilité de conclure à un réel effet, ces résultats montrent une tendance positive selon laquelle l’objectif d’augmentation de la consommation des soins prothétiques de la réforme semble se réaliser. Cette étude souligne l’importance d’évaluer les répercussions à long terme de la crise Covid et de la réforme 100 % s anté sur les consommations de soins dentaires.
