Published: October 2023

The co-culturing of microorganisms is a well-known strategy to study microbial interactions in the laboratory. This approach facilitates the identification of new signals and molecules produced by one species that affects other species’ behavior. In this work, we have studied the effects of the interaction of nine Streptomyces species (S. albidoflavus, S. ambofaciens, S. argillaceus, S. griseus, S. lividans, S. olivaceus, S. parvulus, S. peucetius, and S. rochei) with the predator bacteria Myxococcus xanthus, five of which (S. albidoflavus, S. griseus, S. lividans, S. olivaceus, and S. argillaceus) induce mound formation of M. xanthus on complex media (Casitone Yeast extract (CYE) and Casitone tris (CTT); media on which M. xanthus does not form these aggregates under normal culture conditions. An in-depth study on S. griseus–M. xanthus interactions (the Streptomyces strain producing the strongest effect) has allowed the identification of two siderophores produced by S. griseus, demethylenenocardamine and nocardamine, responsible for this grouping effect over M. xanthus. Experiments using pure commercial nocardamine and different concentrations of FeSO4 show that iron depletion is responsible for the behavior of M. xanthus. Additionally, it was found that molecules, smaller than 3 kDa, produced by S. peucetius can induce the production of DK-xanthenes by M. xanthus.
Training-Induced Increase in V·O2max and Critical Power, and Acceleration of V·O2 on-Kinetics Result from Attenuated Pi Increase Caused by Elevated OXPHOS Activity
Authors: Korzeniewski Bernard 
Published: October 2023

Computer simulations using a dynamic model of the skeletal muscle bioenergetic system, involving the Pi-double-threshold mechanism of muscle fatigue, demonstrate that the training-induced increase in V·O2max, increase in critical power (CP) and acceleration of primary phase II of the V·O2 on kinetics (decrease in t0.63) is caused by elevated OXPHOS activity acting through a decrease in and slowing of the Pi (inorganic phosphate) rise during the rest-to-work transition. This change leads to attenuation of the reaching by Pi of Pipeak, peak Pi at which exercise is terminated because of fatigue. The delayed (in time and in relation to V·O2 increase) Pi rise for a given power output (PO) in trained muscle causes Pi to reach Pipeak (in very heavy exercise) after a longer time and at a higher V·O2; thus, exercise duration is lengthened, and V·O2max is elevated compared to untrained muscle. The diminished Pi increase during exercise with a given PO can cause Pi to stabilize at a steady state less than Pipeak, and exercise can continue potentially ad infinitum (heavy exercise), instead of rising unceasingly and ultimately reaching Pipeak and causing exercise termination (very heavy exercise). This outcome means that CP rises, as the given PO is now less than, and not greater than CP. Finally, the diminished Pi increase (and other metabolite changes) results in, at a given PO (moderate exercise), the steady state of fluxes (including V·O2) and metabolites being reached faster; thus, t0.63 is shortened. This effect of elevated OXPHOS activity is possibly somewhat diminished by the training-induced decrease in Pipeak.
L’éducation partagée : une idée neuve ?
Authors: Richez Jean-Claude 
Published: October 2023

«A priori», la notion d’éducation partagée va de soi et relève du sens commun. Si l’on interroge autour de soi «qui éduque ?», il est répondu spontanément : les parents et l’école. C’est ce qui ressort d’ailleurs d’un sondage récent TNS Sofres. Pourtant, au-delà des évidences, la coresponsabilité éducative soulève des questions et rencontre des obstacles.

Il y a dix ans, je rédigeais un article pour la revue Ville-École-Intégration à l'issue d''un travail de recherche entrepris comme membre de l''équipe ESCOL portant sur l''évolution de la question sociale à l'École et celle des compétences professionnelles mises en oeuvre. Je proposais d''analyser, à partir de l'émergence de la notion de «lutte contre l''échec scolaire», comment l'interférence de deux champs auparavant distincts, le champ social et le champ scolaire, interrogeait les pratiques professionnelles des personnels de l'Éducation nationale, en particulier le rôle d''interface de l'assistante sociale scolaire, au croisement de ces deux champs. Dix plus tard, en 2009, qu'en est-il ?
De la mixité à l'égalité : un cheminement vers l'indépendance à l'égard du genre
Authors: Marro Cendrine 
Published: October 2023

Depuis 1946, l’égalité entre les sexes est un principe constitutionnel inscrit dans le préambule de la Constitution de la République française, préambule qui stipule que « la loi garantit dans tous les domaines l’égalité de la femme et de l’homme ». Qu’en est-il concernant le domaine scolaire ? Incontestablement des progrès restent à faire dans notre école, pourtant mixte à tous les niveaux scolaires depuis plus de 35 ans, au point que l’on peut se demander si l’égalité entre filles et garçons, femmes et hommes constitue un enjeu contemporain de la mixité à l’école ?
L'« esprit du Pacifique » et le rugby – Le Racing Métro 92
Authors: Martin Marjolaine 
Published: October 2023

Tout comme le Racing Métro 92, presque tous les clubs de l’élite du rugby professionnel français comptent dans leur groupe quelques noms aux accents fidjiens, tongiens ou samoans. Ces derniers se mêlent aux autres joueurs étrangers attirés par le championnat français, des Sud-Africains aux Argentins en passant par les Italiens, les Gallois, les Géorgiens, etc. Le cas des joueurs du Pacifique mérite cependant d’être souligné. Ces pays de l’autre bout du monde, aux dimensions et à la population très modestes (un peu plus de 800 000 habitants pour Fidji, le plus grand des trois, et moins de 200 000 pour Samoa et Tonga) envoient tout de même plusieurs centaines de leurs joueurs, en Top 14 et Pro D2 (soit les 1re et 2e divisions professionnelles). Le travail de terrain anthropologique d’où est tiré cet article a été réalisé lors de la saison 2011-2012, de janvier à avril.
La parenthèse enchantée - Avoir son bac en Seine-Saint-Denis ou les paradoxes de « la réussite »
Authors: Truong Fabien 
Published: October 2023

Le baccalauréat est un diplôme iconique du système scolaire français, autrefois « certificat de bourgeoisie » pour ses rares détenteurs, désormais « passeport ou mirage » car symbole et marqueur des ambivalences de la politique de « démocratisation de l’enseignement » enclenchée dans les années 1980, entre massification et ségrégation. Mais que peut alors signifier, du point de vue des élèves, le fait d’ « avoir son bac » général dans un lycée classé ZEP et localisé en Seine-Saint-Denis, territoire lui aussi iconique en matière de relégation et stigmatisation spatiales, sociales, raciales et scolaires, et consacré institutionnellement comme tel par une politique de discrimination positive territoriale, concomitante à celle de la « démocratisation scolaire » ?

Cet article se propose d’analyser les «structures de retour à l’école», dans leur diversité, en comparant deux établissements dont les différences, voire les divergences, témoignent des tensions entre deux approches très différentes du traitement du problème du décrochage scolaire : la première promeut des dispositifs de formation et d’insertion, tandis que la seconde s’interroge sur les conditions d’une ré-institutionnalisation de l’école.
Les contentieux administratifs de demain
Authors: Meurant Cédric 
Published: October 2023

Essayer de deviner l’avenir est toujours un exercice périlleux. Il l’est encore davantage s’agissant du contentieux administratif puisque ces règles juridictionnelles sont tributaires de la place de l’administration au sein de notre société qui est par définition difficilement prévisible. Néanmoins, le contentieux administratif pourrait « demain » de plus en plus se développer en dehors du prétoire. De même, si le juge administratif pourrait avoir à connaître de litiges similaires à ceux qui l’occupent aujourd’hui, d’autres pourraient disparaître, remplacés par de nouveaux.
Effect of nanocarbon surface curvature on interactions with lithium and its ion
Authors: Kawabata Hiroshi , Tachikawa Hiroto 
Published: October 2023

Abstract
The electronic properties of nanocarbons can be tuned via doping. In this study, the interaction energies of Li with (n,n)-carbon belts (n = 5–20) are investigated using density functional theory to clarify the effect of curvature on doping. The magnitude of the interaction energies range from −20.6 to −14.8 kcal mol−1, with a maximum at n = 8. Essentially, two types of charge transfer occur, depending on the carbon belt diameter. For n ≥ 8, the charge is widely distributed on the carbon belt, whereas for n < 8, back-donation charge transfer to Li occurs.

Published: October 2023

В этом исследовании предлагается алгоритм стратегии шифрования изображений, основанный на HACS, и алгоритме скремблирования, для решения проблем ограниченного пространства ключей, небезопасных структур шифрования и простых для взлома существующих методов шифрования. Для начала изображение шифруется с использованием последовательности, сгенерированной с помощью HACS. Эксперименты показывают, что ключевое пространство схемы превышает 2 и что она очень чувствительна к небольшим изменениям в ключах. Гистограмма зашифрованных изображений распределена равномерно. Почти каждый соседний пиксель имеет коэффициент корреляции, равный нулю. Значения UACI и NPCR близки к идеальным, а значения энтропии зашифрованного изображения близки к восьми. Эксперименты показывают, что метод шифрования, описанный в этой статье, может выдержать обширный криптоанализ, такой как статистические и дифференциальные атаки. Результаты исследования показывают, что предложенные система и алгоритм повысили эффективность шифрования, и что разработанный метод полезен и практичен для криптографии изображений.
This study proposes an image encryption strategy algorithm based on HACS and a scrambling algorithm to solve the problems of limited key space, insecure encryption structures and easy-to-crack existing image encryption methods. To begin with, the image is encrypted using a sequence generated using HACS. Experiments show that the key space of the scheme exceeds 2 and that it is very sensitive to small changes in the keys. The histogram of encrypted images is distributed evenly. Almost every neighboring pixel has a correlation coefficient equal to zero. The UACI and NPCR values are close to ideal, and the entropy values of the encrypted image are close to eight. Experiments show that the encryption method described in this article can withstand extensive cryptanalysis, such as statistical and differential attacks. The results of the study show that the proposed system and algorithm have improved the efficiency of encryption, and that the developed method is useful and practical for image cryptography.

Aim. To evaluate the effect of non-invasive ventilation (NIV) in CPAP (continuous positive airway pressure) mode on the development of reperfusion pulmonary edema after percutaneous balloon pulmonary angioplasty (BPA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH).Materials and methods. The study included 70 patients with CTEPH who underwent the first stage of BPA. Prevention of reperfusion edema was carried out using NIV in the CPAP mode starting from the early postoperative period in combination with oxygen and diuretic therapy (as nedeed). The presence and severity of pulmonary edema was assessed based on clinical signs and data from computed tomography or chest radiography.Results. Patients after BPA were on CPAP therapy: average pressure: 10.0±0,7 hPa. During 1st day, the average time of use was: 990±417 minutes. Prolongation of CPAP therapy >1 day occurred in 26 (37%) patients. Depending on the severity of reperfusion edema to the lungs, patients were divided into 2 groups: group 1 (grade 1, n=42) and group 2 (grade 3-4, n=12). During the observation period, there were no cases of severe reperfusion edema (grade 5), and no cases required the use of invasive ventilation or extracorporeal membrane oxygenation. No complications of CPAP therapy were recorded. The number of PA segments and ΔPFG did not differ, but the PEPSI index was higher in group 2: 41,9 [16,0; 57,9] vs 80.5 [52,5; 111,25], p=0,0146. The number of days before discharge after BPA in patients of group 2 was higher: 4.0 [3,9; 5,5] vs 7,0 [4,6; 10,0] days, p=0,013. Despite the development of reperfusion edema, before discharge the SpO2 values in group 2 were comparable to the baseline: 93,0 [89,9; 94,2] vs 93,0 [89,7; 94,4]Conclusion. Preventive use of NIV in the CPAP mode, starting from the early postoperative period, is safe and makes it possible to achieve optimal clinical results in patients even with moderate and severe lung reperfusion edema after large volumes of surgical intervention.
Classify and Explore the Diversity of Planetary Population and Interior Properties
Authors: Jiang Xiaoming , Jiang Jonathan H. , Burn Remo , Zhu Zong-Hong 
Published: October 2023

Abstract
Classification is an essential method and has been developed widely in astronomy. However, planets still lack a universal classification framework, because the solar system planet sample is too small for statistical analysis. Fortunately, exoplanets supply large samples to help build up synthetic planetary populations then support a classification framework. In this study, we use synthetic populations to explore the diversity and evolution relations of planets. We detect six outstanding clusters in mass–radius space with the kernel density estimation and extract typical planets for each type. The first four types are gas-poor planets, and the last two are gas-rich. For an intermediate type, the light gas envelopes contribute to the observable radius but not the mass. Once the planet is massive enough (3.9 M

J
), its size shrinks with increasing mass due to self-gravity. Based on the evolution tracks and the gas envelopes’ properties, the environment is linked strongly to the gas properties, and it controls which type can form at a specific location. The system with gas giants will be different from those without, including total planet mass and the number of planets in the system. Giant planets shape the whole system by orbital resonance. Each type of planets’ period ratios are different, and gas giants have the most outstanding accumulation peak at 2:1 resonance. In the future, the patterns of observed planets’ retrieved interior structures can help to confirm the suggested classification. However, the structure degeneracy induces high uncertainty, such that the framework will still profit from additional theoretical constraints.
