The dynamical analysis and microcontroller implementation of Josephson junction (JJ) oscillator with quadratic damping and topological nontrivial barrier (JJOQDTNB) is investigated in this paper. JJOQDTNB is described by nonlinear resistive capacitive inductive shunted JJ (NRCLSJJ) with 4π-periodic superconducting current. Two steady-states are obtained from the rate equations describing JJOQDTNB. According to the Routh-Hurwitz criteria, one steady-state is stable and the other steady-state is unstable. JJOQDTNB exhibits periodic oscillations, period doubling route to chaotic oscillations and coexistence between limit cycle and chaotic oscillations. The numerical simulations and microcontroller implementation results of JJOQDTNB show a good qualitative agreement.

Le secteur hôtelier, en quête constante d’excellence et de confort pour sa clientèle, repose sur une consommation importante de ressources naturelles. Derrière l’élégance des établissements et la satisfaction des clients se cache une réalité environnementale préoccupante. Chaque année, l’industrie hôtelière génère des tonnes de déchets plastiques, notamment à travers les bouteilles d’eau, les emballages de produits d’accueil, les accessoires jetables des chambres et l’usage de cartes magnétiques. La présente étude ayant pour thème « Importance de l’écoresponsabilité dans le secteur hôtelier de la ville de Porto-Novo » a pour objectif de contribuer à la pratique de l’écoresponsabilité dans le secteur hôtelier de la ville de Porto-Novo. L’approche méthodologique s’est appuyée sur la recherche documentaire, la collecte des données, le traitement des données et l’analyse des résultats. Les résultats issus de nos investigations révèlent que l’écoresponsabilité est perçue comme essentielle, mais que la mise en œuvre est encore partielle et inégale au sein des structures hôtelières de la ville de Porto-Novo. Comme actions écoresponsables nous pouvons avoir l’économie d’Energie, la gestion et tri des déchets, la réduction de la consommation en eau, utilisation des produits d’entretien écologiques, l’approvisionnement local et bio pour la restauration, la sensibilisation aux gestes écocitoyens, le recyclage des déchets. Toutefois, l'état des lieux aux niveau des hôtels montrent l’utilisation de matière première locale, l’installation de panneaux solaires ou autres énergies renouvelables à hauteur de 100% ensuite la réduction de la consommation en eau et le moins apprécié est l’inexistence de bacs de recyclage, formation au personnel et les produits d’entretien écologiques. Au regard de tout ce qui précède, des actions d’information et de sensibilisation sont à mener pour une hôtellerie durable et respectueuse de l’environnement.

Notre étude part d’une observation : la manière dont les internautes s’arrogent le droit d’annoncer le décès de quelqu’un. Nous constatons en effet, qu’à l’ère des réseaux sociaux, l’annonce de la mort qui, autrefois était réservée à la famille, devient un acte ordinaire, effectué par n’importe quelle personne disposant d’un smartphone et d’une connexion internet. Ce phénomène de plus en plus visible, nous a amené à nous interroger sur nos pratiques discursives. L’analyse du discours, cadre théorique de cette étude, nous a permis d’aborder ce phénomène comme un acte de langage socialement situé, car annoncer la mort, c’est aussi produire une certaine réalité, un effet social et symbolique. L’annonce du décès sur les Réseaux Sociaux ne se contente donc pas d’informer ; elle performativise la mort, la rend visible et partageable L’étude a ainsi mis en lumière une transformation profonde de la manière dont la mort est énoncée, vécue et partagée dans la société contemporaine.

Production of Nile tilapia (Oreochromis niloticus) is constrained by early and uncontrolled reproduction in culture, leading to overpopulation and reduced growth performance. Although sex reversal using 17-α-methyltestosterone effectively produces male monosex populations, its use raises health, environmental, and regulatory concerns. In this context, Carica papaya emerges as a promising natural alternative. This study evaluated the efficacy of Carica papaya seed powders as a substitute for 17-α-methyltestosterone in sex reversal of Nile tilapia, as well as their effects on growth, survival, and water physico-chemical quality in two strains (“Bouaké” and “Brazil”). Sexually undifferentiated larvae were exposed for 28 days to five treatments: a negative control, a positive control (70 mg/kg of 17-α-methyltestosterone), and three diets containing Carica papaya (10, 30, and 50 g/kg), in triplicate. Data were analyzed using two-way ANOVA followed by Tukey’s HSD test (p < 0.05). Water physico-chemical parameters remained stable across treatments (p > 0.05), indicating no confounding environmental effects. Carica papaya powders induced significant masculinization, reaching 85-90 % males in the “Bouaké” strain and 78-82 % in the “Brazil” strain, compared with ≥ 96 % in the 17-α-methyltestosterone treatment. The 10 g/kg dose produced the best growth performance, comparable to the hormonal treatment, while higher doses significantly reduced growth. No significant adverse effects on survival or condition factor were observed. In conclusion, Carica papaya seeds constitute a credible natural alternative to 17-α-methyltestosterone for producing male monosex populations of Oreochromis niloticus, offering a relevant compromise between biological efficacy, environmental safety, and sustainability in semi-intensive aquaculture systems.

Purpose and Design: This study develops and empirically validates a quantum-inspired cognitive predictive–diagnostic framework that re-engineers auditors’ responsibilities in detecting corruption across developed and developing economies. Building upon agency theory, accountability theory, and cognitive–behavioral auditing models, the framework distinguishes between predictive responsibilities (anticipating corruption risk ex-ante) and diagnostic responsibilities (tracing anomalies ex-post) within a unified decision environment. Methods and Approach: Using cross-country public-procurement and audit datasets compliant with the Open Contracting Data Standard (OCDS) and engineering-audit records from 2015–2024, the study integrates machine-learning classification with a quantum-inspired optimization algorithm that allocates audit procedures under time and cost constraints. Panel regressions and difference-in-differences tests assess whether the framework enhances corruption detection efficiency and accountability outcomes. Findings: Results reveal that the quantum-inspired predictive–diagnostic model improves corruption detection rates by 27–35 % and reduces audit resource dispersion by 18 %, with stronger effects in developing economies where traditional control systems are weaker. Auditors applying the framework exhibit higher cognitive adaptability and professional skepticism in complex environments. Originality and Value: This is the first study to operationalize quantum-inspired cognition within auditing responsibilities, bridging behavioral, technological, and institutional dimensions of corruption detection. Theoretical, Practical, Economic, and Social Implications. Theoretically, the framework extends the responsibility–accountability nexus under uncertainty; practically, it offers audit regulators and supreme audit institutions a scalable digital model; economically, it optimizes audit costs; and socially, it strengthens integrity and trust in public financial management.

One of the most important ways to lessen the effects of the COVID-19 pandemic, which has caused an unprecedented global health crisis, is through vaccination. Despite the controversy surrounding COVID-19 vaccines, Covishield has been India's most popular vaccine. One and a half years after vaccination, this study examines the persistence of antibodies against COVID-19, particularly those produced by Covishield. 350 participants in total, equally split between the sexes, were chosen for this analysis. Serious public health consequences may result from the presence of antibodies years after vaccination. Our results demonstrate the effectiveness of vaccination, as 68% of samples had adequate antibody titers (>0.80 U/mL) against COVID-19. The concurrent emergence of neurological, respiratory, and cardiovascular adverse effects in those who mounted a sufficient antibody response was a noteworthy finding, though. On the other hand, individuals who were unable to produce adequate antibody levels frequently had a significant medical history, indicating that a serious illness could impair the immune response to vaccination. The significance of additional research into the variables influencing antibody development and vaccine effectiveness is underscored by these findings, which show the delicate relationship between vaccine efficacy and individual health status.

Background: Obesity is a rising public health concern in Malaysia, with more than half of adults now classified as overweight or obese. Beyond its physical health implications, obesity is strongly associated with weight stigma, which can negatively affect patient care and outcomes. Understanding healthcare students’ attitudes and beliefs toward obesity is critical, as these individuals represent the next generation of clinicians. Objectives: This study aimed to determine the prevalence of weight stigma among medical, nursing, and dentistry students at AIMST University, and to assess whether greater biomedical knowledge among medical students is associated with lower levels of stigma. Methods: A cross-sectional survey was conducted among 300 Year 2 and 3 students (100 each from medicine, nursing, and dentistry). Participants completed validated instruments: the Attitudes Toward Obese Persons (ATOP) scale, the Beliefs About Obese Persons (BAOP) scale, and the Norwegian Obesity Knowledge Questionnaire. Data were collected via Google Forms and analyzed descriptively using Microsoft Excel. Frequencies and percentages were calculated to identify key patterns and trends. Results: Respondents demonstrated mixed attitudes toward obesity. While nearly half (49%) agreed that obese individuals could be as happy as their non-obese counterparts, a significant proportion expressed scepticism regarding self-esteem and confidence among obese persons. More than 60% perceived that obese individuals are dissatisfied with themselves, and over 63% disagreed that obese people are as healthy as non-obese individuals. Beliefs about the causes of obesity were also divided: many participants attributed it to lifestyle and willpower, though a notable proportion acknowledged genetic and biological factors. Conclusion: Despite awareness of evidence-based approaches to obesity management, misconceptions and stigmatizing beliefs remain prevalent among healthcare students. The findings partially contradict the initial hypothesis, showing that medical, nursing, and dentistry students do exhibit weight stigma, though medical students demonstrated comparatively greater awareness of obesity’s complex aetiology. Targeted educational interventions that integrate empathy training, biological education, and inclusive communication strategies are warranted to reduce bias and prepare healthcare students to deliver equitable patient care.

This research analyzed the curricular dynamics relating to the teaching and learning of Ohm's law in Benin. It is useful for laying the foundations for understanding the role of the prescribed curriculum in the many problems highlighted with regard to the teaching and learning of Ohm's law. To this end, it analyzed the prescribed curriculum relating to Ohm's law in the light of Franklin Bobbitt's curriculum theory (Mœglin and Chaptal, 2016) and the methodological framework proposed by Barthès (2022) for analyzing curriculum systems. Research in physics education analyses content as it relates to teaching and learning in the school subject of physics. There is a wealth of research on physical concepts and laws, highlighting the problems associated with teaching and learning them, while attempting to propose solutions to mitigate these problems. Among these difficulties are institutional problems in the organization of teaching and learning of physical laws and concepts, as well as dysfunctions in the organizational implementation of the subject of physics. The question that arises is: to what extent does the prescribed curriculum contribute to the many problems identified in the teaching and learning of Ohm's law? The methodology consisted of a diachronic analysis of curricula and study guides from 1960 to 2020, focusing on axiological and epistemological dimensions. The results indicate that study programs relating to Ohm's law have evolved in a somewhat chaotic manner, both in terms of teaching paradigms, in terms of topics ranging from energetic to electrokinetic via electrostatic, in terms of the vague definitions of Ohm's law, and in terms of curriculum guidelines. This institutional curricular dynamic is likely to create instability in the implementation of Ohm's law in institutional subjects, which should be explored.

In this paper, we delve into the viscous generalized Chaplygin gas (VGCG) model, focusing on its thermodynamic stability. We utilize an equation of state represented as p=-A/ρ^α , where A is a positive universal constant, incorporating bulk viscosity into our analysis. Our study reveals how the thermodynamic properties of the universe change as we vary the bulk viscosity parameter. By examining the thermal equation of state, we find that the equation of state parameter has a direct dependency on temperature. Additionally, we investigate how this exotic viscous fluid contributes to the accelerated expansion of the universe. A key finding is that for the fluid to meet standard stability conditions, the viscosity parameter must be strictly negative, ensuring that (∂p/∂V)_S<0 and (∂p/∂V)_T<0 are satisfied throughout cosmic evolution. Our analysis indicates that the fluid maintains stability during adiabatic processes. We also demonstrate that this model upholds the condition of positive heat capacity at constant volume (c_V) and adheres to the third law of thermodynamics.

Le diabète constitue un enjeu majeur de santé publique qui exige des outils de dépistage précoces et performants. Nous avons étudié l’effet de la taille des données d’entraînement sur les performances d’un modèle Random Forest en construisant quatre versions successives entraînées sur des jeux de données de taille croissante (V3 : 200 patients, V4 : 500 patients, V5 : 1000 patients, V6 : 2000 patients). Les performances ont été évaluées par l’aire sous la courbe ROC (AUC), les matrices de confusion et les métriques de précision/rappel. Les AUC observées étaient les suivantes : V3 = 0,612 ; V4 = 0,720 ; V5 = 0,737 ; V6 = 0,762. La version finale (V6) a permis d’atteindre une sensibilité très élevée (98%) soit seulement 2% de faux négatifs —au seuil retenu pour privilégier la détection des cas positifs, au prix d’une hausse des faux positifs. L’augmentation de la taille des données d’entraînement a amélioré la stabilité et la discrimination du modèle, facilitant son ajustement vers une sensibilité maximale, ce qui est particulièrement utile pour des stratégies de dépistage clinique. L’étude valide le modèle V6 de prédiction du diabète sur trois patients réels hospitalisés en contexte tchadien, démontrant sa capacité discriminatoire à identifier les profils sains, à risque et diabétiques confirmés. Le système génère des recommandations cliniques adaptées à chaque niveau de risque avec une explicabilité transparente.

This study evaluates and compares three physicochemical pretreatment processes: sodium hydroxide precipitation, , lime precipitation, and electrocoagulation (EC) for calcium and magnesium removal from landfill leachate to mitigate scaling and improve compatibility with downstream biological treatment. FTIR analysis of scale deposits collected from heat exchanger plates confirmed calcite (CaCO₃) as the dominant scaling compound, highlighting the need for calcium removal before biological treatment. Batch experiments conducted on real landfill leachate collected during the winter season showed that sodium hydroxide precipitation achieved the highest removal efficiencies, with simultaneous calcium and magnesium removals exceeded 96% under optimal conditions of pH 12, stirring speed of 50 rpm and reaction time of 1 min. This indicated extremely fast equilibrium-controlled kinetics. Lime precipitation provided moderate calcium removal (73.0%) and good magnesium removal (87.2%). However, it was limited by high sludge production and dosage sensitivity. Electrocoagulation achieved high calcium removal (92.7%) and moderate magnesium removal (64.1%) under optimal conditions of current density of 4.5 mA/cm2 and treatment time of 30 min. EC avoided chemical addition and extreme pH adjustment. Although sodium hydroxide precipitation showed higher simultaneous removal performances, EC emerged as a promising alternative, offering reduced chemical consumption and greater operational flexibility. The results of the present study demonstrated the relevance of physicochemical pretreatment to enhance the reliability and sustainability of landfill leachate treatment systems.

Experimental densities (ρ), viscosities (η), and ultrasonic velocities (U) for the binary mixture of ethyl benzoate (component 1) with 2-methyl-1-propanol (component 2) were measured at 303.15, 308.15, 313.15, and 318.15 K over the entire composition range at atmospheric pressure. From these data excess properties—including excess molar volume (V^E), excess adiabatic compressibility (Δβ_ad), excess viscosity (Δη), excess free length (L_f^E), excess internal pressure (π^E), excess acoustic impedance (Z^E), excess Gibbs free energy (G^E), excess enthalpy (H^E) and excess ultrasonic velocity (U^E)—were calculated. Negative values of V^E and Δβ_ad over entire mole fraction ranges indicate strong specific interactions, likely hydrogen bonding, between unlike molecules. The temperature dependence of excess functions reveals enhancement of interaction strength at higher temperatures. Results are discussed in terms of structure–interaction relationships and correlated with Redlich–Kister polynomial fits.
