Stellar activity contamination of radial velocity (RV) data is one of the top challenges plaguing the field of extreme-precision RV science. Previous work has shown that photometry can be very effective at removing such signals from RV data, especially stellar activity caused by rotating starspots and plage. The exact utility of photometry for removing RV activity contamination, and the best way to apply it, is not well known. We present a combination photometric and RV study of eight Kepler/K2 FGK stars with known stellar variability. We use NEID RVs acquired simultaneously with Transiting Exoplanet Survey Satellite (TESS) photometry, and we perform injection-recovery tests to quantify the efficacy of recent TESS photometry versus archival Kepler/K2 photometry for removing stellar variability from RVs. We additionally experiment with different TESS sectors when training our models in order to quantify the real benefit of simultaneously acquired RVs and photometry. We conclude that Kepler photometry typically performs better than TESS at removing noise from RV data when it is available, likely due to longer baseline and precision. In contrast, for targets with available K2 photometry, especially those most active, and with high-precision (σ
NEID <  1 m s−1) NEID RVs, TESS may be the more informative dataset. However, contrary to expectations, we have found that training on simultaneous photometry does not always achieve the best results.

We study the structure, interstellar absorption, color–magnitude diagrams (CMDs), kinematics, and dynamical state of embedded star clusters in the star-forming region associated with the giant molecular cloud G174+2.5. Our investigation is based on photometric data from the UKIDSS Galactic Plane Survey catalog and astrometric data from the Gaia DR3 catalogs. First, we recover all the known embedded clusters and candidate clusters in the region using surface density maps. Then, for the detected clusters, we determine their general parameters: the center positions, radii, number of stars, and reddening. To evaluate the reddening, we use both the NICEST algorithm and the Q-method. Both methods produce consistent extinction maps in the regions of the four studied clusters. However, the Q-method yields a much smaller color scatter in the CMD. For four clusters in particular (S235 North-West, S235 A-B-C, S235 Central, and S235 East1+East2), we were able to compute individual membership probabilities, the cluster distances, the cluster masses, and their average proper motions. By building on these results, we have studied the clusters’ kinematics and dynamics. Moreover, we estimate the mass of the gas component and the star formation efficiency in the regions of these four clusters. Finally, we provide an estimate of the total energy of the stellar and gas components in the area of these four clusters to determine whether the clusters are bound (here, we consider a “cluster” as the system “stars + gas”). The gravitational bound strongly depends on the region for which we estimate the gas mass. If we consider the mass of the entire cloud, all these four clusters turn out to be bound.

Published: January 2025

Using archival Hubble Space Telescope observations, we report the discovery of four variable low-mass white dwarfs (WDs; 0.18 M
⊙ ≤ M ≤ 0.5 M
⊙) in the globular cluster NGC 6397. One source exhibits a periodic optical modulation of 5.21 ± 0.02 hr, which we interpret as potentially due to the rotation of a magnetic helium core WD (He WD). This makes this candidate the second magnetic He WD in NGC 6397, and one of the few He WDs with a measured rotation period. The other three candidates show aperiodic variability, with a change in magnitude ranging from ∼0.11 to 0.6. These discoveries highlight the importance of high-cadence photometric surveys in dense stellar environments. Follow-up spectroscopic observations are needed to confirm the nature of the variability of these systems.
Cirrhimuraena taiwanensis sp. nov., a new species of cirri-bearing eel (Anguilliformes, Ophichthidae) from Yilan, northeastern Taiwan
Authors: Lin Yen-Ting , Lin Yu-Hsiang , Han Yu-San
Published: January 2025

A new species of cirri-bearing eel, Cirrhimuraena taiwanensissp. nov. (Anguilliformes, Ophichthidae), is described based on a specimen collected from the estuary of the Langyang River (Yilan County), northeastern Taiwan. The new species is distinct from all congeners, except C. odishaensis and C. orientalis, in possessing a single row of mandibular teeth. Cirrhimuraena taiwanensissp. nov. differs from C. odishaensis in having significantly shorter pectoral fins and fewer vertebrae, and it is distinguished from C. orientalis by its larger head, notably more total vertebrae, and a dorsal fin that originates well behind the gill opening. In the neighbor-joining tree based on COI sequences, the new species forms a distinct monophyletic group; thus, it is clearly separable from congeners both morphologically and genetically. With this addition, there are now 13 species in the genus Cirrhimuraena.
L’ordre constitutionnel de transition en Afrique : étude des cas à partir des États d’Afrique noire francophone
Authors: Mermoz Bikoro Jean
Published: January 2025

Le droit constitutionnel africain est décidément résilient. Quand bien même la survenance d’une crise débouche sur la déconstitutionnalisation de la vie politique, on assiste à l’émergence de normes dont la vocation est d’encadrer à titre provisoire l’organisation et le fonctionnement du pouvoir. Ainsi, à l’ordre constitutionnel ordinaire, se substitue un ordre constitutionnel de transition chapeauté par une Constitution intérimaire. À l’analyse, il s’agit d’un ordre de nécessité qui a la particularité d’être fondamentalement programmatique.
Les ordonnances constitutionnelles de l’armée : essai de réflexion théorique sur une catégorie juridique complexe
Authors: Bombela Mosoua Ghislain
Published: January 2025

Longtemps ignorées et laissées aux oubliettes dans l’étude du constitutionnalisme africain, les ordonnances militaires refont surface avec la recrudescence des coups d’État que traverse le continent noir ces dernières années. Entre 2021 et 2023, ce n’est pas moins de sept coups d’État qui ont secoué l’Afrique : le Tchad le 21 avril 2021, le Mali deux coups d’État en neuf mois le 18 août 2020 et le 24 mai 2021, la Guinée le 5 septembre 2021, le Soudan le 25 octobre 2021, le Burkina Faso le 24 janvier 2022, le Niger le 26 juillet 2023 et le Gabon le 30 août 2023. Cet état des choses traduit le retour de l’armée au pouvoir et la restauration des régimes militaires en Afrique. En accédant au pouvoir, les militaires entrainent une rupture de la légalité constitutionnelle. Cette rupture de l’ordre constitutionnel balise la voie aux ordonnances militaires, qui constituent la nouvelle légalité constitutionnelle des États africains en crise ou en transition. Il en ressort donc qu’il existe un double ordre constitutionnel au sein des États africains. Un ordre constitutionnel normal en temps de paix et un ordre constitutionnel de crise ou d’exception en contexte de coup d’État, généralement fondé sur les ordonnances constitutionnelles de l’armée. L’objectif de la présente réflexion est d’effectuer une analyse juridique serrée de cette catégorie juridique complexe. Pour ce faire, seront mobilisés comme outils théoriques et méthodologiques le décisionnisme tel que défendu par Carl Schmitt, le néoréalisme juridique, l’histoire et les pratiques constitutionnelles des États africains.
À la recherche d’un ordre constitutionnel démocratique en Afrique subsaharienne francophone
Authors: Sobze Serge François
Published: January 2025

De quel ordre constitutionnel parle-t-on ? Après les tumultes de la démocratie politique caractérisée dans les années 1990 par les résistances, les succès et les insuccès, l’Afrique noire s’est résolument mise à la recherche d’un ordre constitutionnel qui serait propulseur d’un État de droit démocratique. Elle s’est inspirée des valeurs constitutionnelles et a-constitutionnelles, plus précisément des objectifs et principes énoncés dans l’Acte constitutif de l’Union africaine tels que la bonne gouvernance, la participation populaire, l’État de droit et les droits de l’homme. La présente contribution se propose de déconstruire et de reconstruire une nouvelle grille d’analyse à partir des crises politiques et institutionnelles actuelles, considérées comme des obstacles à l’enracinement d’un ordre démocratique à visage humain en Afrique. Cette réflexion qui se veut une analyse reposant sur l’exégèse et sur la sociologie des normes, suggère de sortir l’ordre constitutionnel africain de son état alité ou émasculé pour un ordre constitutionnel vivifié ou revitalisé.

Published: January 2025

Introduction : L’intégration de la prise en charge du diabète de type 1 (DT1) au Cameroun est un défi. En dépit de certaines initiatives de fourniture d’insuline gratuite aux enfants, la prise en charge est encore insuffisante. But de l’étude : Cette étude explore les expériences et les recommandations des professionnels de soins et des familles comme acteurs pour intégrer la prise en charge du DT1 dans le système de santé au Cameroun. Méthodes : Trente-huit entretiens semi-structurés approfondis ont été réalisés : cinq experts du ministère de la Santé, treize personnels soignants et vingt familles (n = 23 membres des familles). Une approche itérative a été utilisée dans le cadre de l’analyse thématique. Le codage des catégories a été pris en charge par QDA Miner 5.0.31 (Provalis). Résultats : Les participants ont révélé que la prise en charge du DT1 devait être davantage valorisée et considérée comme un enjeu gouvernemental. Les professionnels de soins et les familles ont souligné les défis organisationnels, la stigmatisation et la non-compréhension de la maladie comme des obstacles majeurs. En revanche, le personnel soignant a mis l’accent sur la charge du travail due au manque de personnel formé et éduqué sur le DT1, et les problèmes d’infrastructures, obstacles aux aspects d’intégration de la prise en charge du DT1. Conclusions : Malgré des efforts organisés, les professionnels de la santé et familles ont relevé de multiples obstacles à une intégration réelle de la prise en charge du DT1. Les résultats suggèrent des options/recommandations pour relever les défis communautaires dans l’optique d’une prise en charge du DT1 plus intégrée et participative.
Analysis of a reaction-diffusion AIDS model with media coverage and population heterogeneity
Authors: Zhang Xiang , Zheng Tingting , Luo Yantao , Liu Pengfei
Published: January 2025

Considering the influence of population heterogeneity, media coverage and spatial diffusion on disease transmission, this paper investigated an acquired immunodeficiency syndrome (AIDS) reaction-diffusion model with nonlinear incidence rates and media coverage. First, we discussed the positivity and boundedness of system solutions. Then, the basic reproduction number $ \mathcal{R}_0 $ was calculated, and the disease-free equilibrium (DFE), denoted as $ E^0 $, was locally and globally asymptotically stable when $ \mathcal{R}_0 < 1 $. Further, there existed a unique endemic equilibrium (EE), denoted as $ E^* $, which was locally and globally asymptotically stable when $ \mathcal{R}_0 > 1 $ and certain additional conditions were satisfied. In addition, we showed that the disease was uniformly persistent. Finally, the visualization results of the numerical simulations illustrated that: The media coverage was shown to mitigate the AIDS transmission burden in the population by lowering the infection peak and the time required to reach it; a higher awareness conversion rate can effectively reduce the basic reproduction number $ \mathcal{R}_0 $ to curb the spread of AIDS.
A recursive filter for a class of two-dimensional nonlinear stochastic systems
Authors: Kong Shulan , Wang Chengbin , Sun Yawen
Published: January 2025

A recursive filtering problem on minimum variance is investigated for a type of two-dimensional systems incorporating noise and a random parameter matrix in the measurement equation, along with random nonlinearity. It methodically describes random variables using statistical characteristics, placing a strong emphasis on the application of random multivariate analysis and computational techniques. A bidirectional time-sequence recursive filter is designed to achieve unbiasedness and reduce error variance effectively. This involves deriving the gain matrix through a completion of squares method and solving a complex difference equation with two independent variances. To facilitate the online implementation of this filter, various formulations and an algorithm are proposed. A numerical study demonstrates the effectiveness of the design in practical applications.

Published: January 2025

Using the binary operation "$ {\Lsh} $" on a GE-algebra $ {X} $ given by $ {\Lsh}({x}, {y}) = ({y}{*} {x}){*} {x} $ and the GE-endomorphism $ {\Omega} : {X} \rightarrow {X} $, the notion of $ {\Omega}_{(l, r)} $-endomorphic (resp., $ {\Omega}_{(r, l)} $-endomorphic) GE-derivation is introduced, and several properties are investigated. Also, examples that illustrate these are provided. Conditions under which $ {\Omega}_{(l, r)} $-endomorphic GE-derivations or $ {\Omega}_{(l, r)} $-endomorphic GE-derivations to satisfy certain equalities and inequalities are studied. We explored the conditions under which $ {f} $ becomes order preserving when $ {f} $ is an $ {\Omega}_{(l, r)} $-endomorphic GE-derivation or an $ {\Omega}_{(r, l)} $-endomorphic GE-derivation on $ {X} $. The $ {f} $-kernel and $ {\Omega} $-kernel of $ {f} $ formed by the $ {\Omega}_{(r, l)} $-endomorphic GE-derivation or $ {\Omega}_{(l, r)} $-endomorphic GE-derivation turns out to be GE-subalgebras. It is observed that the $ {\Omega} $-kernel of $ {f} $ is a GE-filter of $ {X} $. The condition under which the $ {f} $-kernel of $ {f} $ formed by the $ {\Omega}_{(r, l)} $-endomorphic GE-derivation or $ {\Omega}_{(l, r)} $-endomorphic GE-derivation becomes a GE-filter is explored.
Les artisans et la terre : réflexions sur les concessions foncières aux artisans altomédiévaux (ixe‑xie siècles)
Authors: Beaudet Alexandre
Published: January 2025

Les rapports fonciers des artisans altomédiévaux sont des éléments structurants de leurs relations de production et constituent donc un terrain de recherche privilégié pour l’histoire du travail. Cet article cherche à poser les bases d’une réflexion sur les formes de concessions foncières accordées aux artisans altomédiévaux, de manière à nuancer le lieu commun du tenancier-artisan. Il se concentre sur le lien entre ces concessions et les relations de production des artisans. Ainsi, trois documents qui lient explicitement le savoir-faire artisanal à la terre sont principalement mis à profit : le premier est le cas célèbre des fabri de la villa de Boissy dans le polyptyque de Saint-Germain-des-Prés. Le deuxième concerne la conversion d’un loyer agricole en un loyer composé d’outils en fer par le faber Gudepert. Le troisième document est un bail emphytéotique concédé par l’évêque de Ravenne à trois maçons et dont une clause l’attache à la pratique de leur savoir-faire. Mis en relation avec d’autres exemples, notamment des bénéfices concédés à des artisans, ces cas montrent que les terres tenues par des artisans ne peuvent pas être systématiquement interprétées comme des tenures exploitées par ceux‑ci et que leurs fonctions sont multiples : la rémunération, la compensation, l’entretien d’une relation personnelle et la pérennisation d’un savoir-faire. De plus, l’ampleur et la nature de certains biens fonciers prouvent que les artisans n’étaient pas nécessairement exploitants de la terre, ils pouvaient aussi en être les rentiers.
«El Camino que nos une»: una historia política del Qhapaq Ñan
Authors: Espinoza Martín Oscar
Published: January 2025

El artículo aborda cómo el Qhapaq Ñan, texto y artefacto al mismo tiempo, está relacionado forzosamente con la historia del Perú contemporáneo y con determinadas narrativas sobre la vialidad, la integración y las poblaciones indígenas. El Qhapaq Ñan ha sido parte de las discusiones de la clase política peruana al menos desde inicios del siglo XX, como (pre)texto para legitimar determinadas políticas económicas y el lugar de las poblaciones indígenas en el proyecto de nación. A inicios del siglo XXI, el Qhapaq Ñan devino en uno de los artefactos patrimoniales más políticos de la historia peruana reciente, participando en espacios de encuentro diplomático, alianzas regionales y políticas bancarias. Así, desde una perspectiva global, las «calzadas» del camino prehispánico se transformaron en nodos de una cartografía política que va más allá de las fronteras de los Estados nación.

Published: January 2025

The aim of this study was to compare between morphological and molecular identification methods. Two strains (A1, A2) of Aspergillus sp. isolated from El-Baida marsh, were subjected to be identified using morphological characterization, and molecular analysis performed by amplification of the ITS1 and ITS4 regions of rDNA. Morphological analysis indicated that both strains were identified as Aspergillus oryzae. However, by molecular methods A1 strain was identified as Aspergillus alliaceus and A2 strain as Aspergillus oryzae. Our results showed that phenotypic methods were insufficient for correct identification, and the use of genotypic methods is the most reliable. Enzymatic activity of the A2 isolate was evaluated using a plate assay for Lipase, Amylase and Protease production; the results illustrated the capacity of the fungus of the production of the three enzymes, which are mostly used in the production of pharmaceuticals, foods, beverages, and textile. They are found in a vast variety of sources such as animals, plants and microorganisms but microbial enzymes are more stable than the others. In addition, the reality that this fungus is known as a safe microorganism in several domains (food, beverage, cosmetic, and pharmaceutical industries), this opens the research in the future.
Insecticidal activities of natural volatile compounds against pulse beetle, Callosobruchus chinensis (Bruchidae)
Authors: Chaubey Mukesh Kumar
Published: January 2025

Two pure natural volatile compounds, carvacrol and menthone were investigated for repellent, insecticidal, ovipositional and egg hatching inhibition activities against pulse beetle, Callosobruchus chinensis (Coleoptera: Bruchidae). Carvacrol and menthone repelled bruchid adults in choice oviposition assay. Both compounds caused toxicity, reduced oviposition potential and viability of eggs significantly when fumigated. In chronic toxicity assay, both carvacrol and menthone reduced F1 progeny production and weight loss in cowpea seeds. Reduced in grain damage was probably occurred due to inhibition of oviposition and egg hatching. Acetylcholine esterase enzyme activity was inhibited in adults when fumigated with carvacrol and menthone showing neurotic mode of action. Findings of the present study suggest that application of carvacrol and menthone can be effective in the management of C. chinensis.

Considering the growth of aquaculture and its potential environmental impacts, this study aimed to evaluate the patterns and trends of research on water quality in fish farms in Brazil, focusing on environmental differences between fishponds and net cages. We conducted a bibliometric survey from the Aquatic Sciences and Fisheries Abstracts (ASFA) and Web of Science databases, using the keywords "fish farm" or "fishpond" and "monitoring" and "water quality". After screening the retrieved documents, a total of 37 original studies were selected. Publication year, locality, pond type, culture characteristics, trophic state index, and values of chemical, physical and biological variables were collected. It was observed an increasing trend in the number of studies over time, with publication peaks in 2014 and 2018. Net cages were evaluated by 60% of the published research, which included between 3 and 750 tanks per study. Fishponds were evaluated by the remaining fraction of the studies, which included from 1 to 50 tanks per study. The five regions of the country were unequally represented: Southeast (54%), Northeast (24%), South (14%), North (5%), and Midwest (3%). Forty-seven distinct variables were recorded, and the most frequent were temperature, dissolved oxygen, and ph. Significant differences were observed in total phosphorus, chlorophyll-a, and orthophosphate concentrations among different pond types, with higher values in fishponds. The findings of our study showed high potential for eutrophication in the aquaculture systems in Brazil and highlighted the urgency for an effective management of this activity in the country. Nevertheless, there is still a lack of information and studies on this topic to support informed decision-making. We also propose some general guidelines.

Due to profuse bureaucracy and high costs of high purity potassium nitrate (KNO3), we intend to check the possibility of replacing this reagent with a similar commercial mineral fertilizer that costs less and is easier to procure. The experiment consisted of seven treatments with the fertilizer Dripsol® NKS, replacing the high purity potassium nitrate (KNO3 PA) in the culture medium for rooting gerbera. The control treatment (T1) consisted of inorganic MS salts, containing 1.9 g L-1 KNO3 PA and, in the other treatments, the KNO3 of the MS medium was replaced by the fertilizer in the following concentrations (g L-1): T2 0; T3; 0,5; T4; 1,0; T5; 1,5; T6; 2,0 e T7; 2.5. In the rooting phase, after 35 days in the growing room, the average length of the root, the average length of the aerial part, the number of leaves, and the fresh biomass average value of the hybrid Gerbera DTCS were evaluated. Fertilizer at a concentration of 0.5 g L-1 generated results equal to or greater than those of the control treatment for all variables analyzed in vitro conditions. In the ex vitro experiment, seedlings from the in vitro cultivation with commercial fertilizer were acclimated and later transplanted to a vivarium where their development was monitored until flowering. In this experiment, the average root length, average number of roots, average length of the aerial part, number of leaves, leaf area, fresh biomass average value, and absorption of macronutrients (during the vegetative phase) were assessed. No morphological changes were observed. In view of the results, it was possible to prove the feasibility of replacing KNO3 (PA) for the commercial NKS® fertilizer in the preparation of the culture medium for in vitro propagation of gerbera, in a smaller rate, thus reducing approximately 97.0% of costs and eliminating bureaucratic obstacles applicable to the procurement of KNO3.

Among the several native Brazilian plant species that have yet to be studied for their medicinal properties is Verbesina macrophylla, popularly known as “assa-peixe”. The popular use of this species for medicinal purposes has been reported in southeastern Bahia State, with leaf tea being used to treat renal and urethral problems with anti-inflammatory and antifebrile activities, and flower tea to treat inflammation. Despite the potential medicinal importance of V. macrophylla, studies of its chemical composition and possible activity in controlling fungi and parasites are scarce and recent. This study tested the biological activity of aqueous extracts of leaves and inflorescences of V. macrophylla on the yeasts Candida albicans and Candida tropicalis, the filamentous fungus Fusarium oxysporum, and the epimastigote form of Trypanosoma cruzi. Inflorescence extract showed an inhibitory activity of 41% for cells of C. tropicalis, causing changes in the plasma membrane, resulting in fungicidal activity. Both aqueous extracts eliminated epimastigotes with a dose/time-dependent relationship, reaching 100% elimination after treatment with 200 μg mL-1 of either, causing cytoplasmic and nuclear disorganization, vacuolization and enlargement of the reservosomes. Although the studied extracts did not present considerable inhibitory activities against the filamentous fungus and yeasts, promising results were seen with the epimastigote form of T. cruzi. These data add industrial and medicinal value to the species. Additional studies are needed, particularly spectrometric analysis of extracts, to elucidate the metabolite(s) responsible for the results of this study.

Biological specimens are essential for teaching, research, and extension, although they require effective preservation. The glycerination technique stands out for allowing specimens to be preserved dry, which saves costs and facilitates handling due to specimen malleability. We sought to establish an optimal glycerination protocol for fish and reptiles for teaching purposes. Several fixatives were tested, including formalin at different concentrations and Transeau solution. The fixation process involved injecting a 50% fixative and 50% double-distilled glycerin solution into the specimen, followed by immersion in the same fixative. After seven days animals were washed, partially dried, and subsequently immersed for 60 days in double-distilled glycerin with camphor. The specimens were then kept in air-conditioned environments with a dehumidifier during a 30-day drying period. A 3% formalin solution was found to be the most efficient, guaranteeing the mental 10 some of the specimens’ colors, and their malleability. This study contributes to the optimization of glycerination preservation and effectively preserving fish and reptile specimens for teaching purposes while reducing handling risks.
