This work proposes a decentralized mechanism for the verification and restoration of public keys in passkey-based authentication systems. The model relies on a synergistic integration of Blockchain and the distributed file system IPFS, aiming to eliminate dependence on a centralized trusted third party and to enhance the resilience of public key storage. Unlike traditional approaches where the compromise of the public key repository on the Relying Party (RP) leads to identity spoofing, our mechanism ensures the integrity, traceability, and availability of keys in the event of tampering. The experimental analysis highlights the advantages of the hybrid on/off-chain model in terms of scalability, demonstrating a significant improvement in throughput and a reduction in gas costs compared to a fully on-chain architecture. Finally, the formal evaluation conducted under the Dolev–Yao model usi...

Experimental cybersecurity research has traditionally relied on using datasets to train intrusion detection systems (IDS). However, current solutions suffer from outdated reference data and an event-centric approach limited to binary traffic classification or attack type identification. This article argues that threat anticipation requires a paradigm shift toward attacker profiling. Following a critical review of existing cybersecurity datasets, we introduce a novel dataset for Cyber Attackers Profiling Enhancement (MITRE-CAPE-2026), an dataset constructed from the execution of attack scenarios derived from the Atomic Red Team platform on a T-Pot–based deceptive infrastructure. The collected data were subsequently labeled according to the MITRE ATT&CK framework. The resulting dataset comprises 1,918 attack scenarios collected across Linux, Windows, macOS, and cloud environments, covering...

Aims: In Burkina Faso, the processing of dried food products contributes to the valorisation of local resources, the reduction of post-harvest losses and the improvement of food security. Despite the increasing importance of these products in dietary habits, data on their physicochemical and microbiological quality remain limited. This study assessed the physicochemical and microbiological characteristics and level of compliance of six dried and instant food products (bassi, granulated bissap, dried dègué, infant flour, granulated ginger and zoom-koom) produced by a local agro-food processing enterprise in Burkina Faso. Methodology: A descriptive and analytical study was conducted between July and September 2025 using 18 samples, with three samples per product type. The analyses included pH, titratable acidity, moisture content and dry matter, as well as microbiological quality a...

Tropical medicinal plants constitute an important source of structurally diverse metabolites with potential value for pharmaceutical, nutraceutical and biotechnological research. Conventional natural-product discovery pipelines, however, remain limited by slow metabolite identification, fragmented ethnobotanical information and restricted translation from screening to validated candidates. This review examines Bioprospecting 4.0 as an integrated framework that combines untargeted metabolomics, ethnobotanical databases, artificial intelligence, cheminformatics and systems biology for the prioritisation of bioactive molecules from tropical medicinal plants. Particular attention is given to LC-MS/MS-based metabolomics, molecular networking, NMR-supported structural elucidation, knowledge graphs and AI-assisted prediction of biological targets and ADMET properties. The review also considers...

Cette étude analyse les liens entre l’agentivité reproductive des femmes et deux résultats de santé reproductive au Burkina Faso : l’utilisation d’une méthode contraceptive moderne et l’expérience de rapports sexuels non souhaités. À partir des données PMA collectées auprès des femmes en âge de procréer (15-49 ans), cette recherche utilise une mesure multidimensionnelle de l’agentivité adaptée à la santé reproductive. Les résultats montrent qu’une motivation élevée en contraception est associée à des chances plus élevées d’utiliser la méthode contraceptive moderne (OR = 2,22 ; p < 0,001). Une motivation élevée en contraception est également associée à un risque plus réduit d’avoir un rapport sexuel non souhaité (OR = 0,55 ; p < 0,05). Ces résultats soulignent l’importance des dimensions motivationnelles de l’autonomie reproductive dans un contexte où les normes de genre, les attentes de...

Background The widespread mobilisation to improve maternal health over recent decades has led to increased prenatal consultations and assisted deliveries, resulting in a significant reduction in maternal mortality in many sub-Saharan African countries. This paper examines the progress made in basic obstetric care in four sub-Saharan African countries (Burkina Faso, Côte d’Ivoire, Ghana and Senegal), and investigates the sources of this progress to better inform future policy actions that will help achieve the Sustainable Development Goal 3 targets related to maternal and child health. Methods We used data from two Demographic and Health Surveys (DHSs) conducted in each of the four countries in the early 2010s and 2020s by their respective national statistical offices. Specifically, we relied on the 2010 and 2021 DHS for Burkina Faso, the 2011 and 2021 DHS for Côte d’Ivoire, the 20...

The work presented in this paper is part of the general framework of mathematical ecology regarding the complex dynamics in predatory prey model. The main objective is the formulation and study of a prey-predator model to describe the dynamics of fish and zooplankton population taking into account two phenomenons: the catching effect in the fish population and the age-structure in the zooplankton dynamics. We present some mathematical results concerning the positive solution existence, the stability and persistence of the model equilibria using a positive initial condition. The total population of zooplankton and the total population of fish are uniformly weakly persistent if R0 1 and R 1. Some numerical simulations according to the mathematical conditions are performed using the finite volume method, are done to illustrate those results in the different fish exploited and inexploited ar...

Les formes orales liquides de furosémide sont très peu disponibles sur le marché. Les alternatives de préparation sur mesure réalisées en milieu hospitalier pour la prise en charge des patients pédiatriques présentent des phénomènes d’instabilité. L’objectif de cette étude était de mettre au point des comprimés à dispersion rapide de furosémide destinés aux patients pédiatriques. Des comprimés à dispersion rapide ont été formulés. Ils renfermaient un diluant inspiré de la formulation du Pharmaburst C1® , 20% m/m de cellulose microcristalline, 1 à 4% m/m de croscarmellose sodique, 0,5% m/m de stéarate de magnésium, 2,5% m/m de benzoate de sodium et 0,1% m/m de saccharinate de sodium. Les caractéristiques rhéologiques des mélanges pulvérulents ont été déterminées avant leur compression directe. L’aspect, la masse moyenne, la dureté, la friabilité, le dosage et la dissolution des comprimés...

Small-scale irrigation (SSI) technologies are essential for boosting agricultural production, reducing drought risks, and enhancing climate resilience in the Sahel. This study examines vegetable growers’ preferences for irrigation technology packages in Kadiogo Province, Burkina Faso, using a discrete choice experiment conducted with 208 farmers in the communes of Komsilga and Tanghin-Dassouri. Preferences and welfare effects were estimated through conditional logit and random parameter logit models. The results show strong and significant preferences for semi-Californian irrigation systems (a surface gravity-fed distribution system using lateral pipes), sprinkler systems, and motorised pumps, particularly solar-powered pumps. These choices reflect farmers’ priorities for ease of use, energy independence, and expected productivity gains. In contrast, drip irrigation systems, extension se...

This study examines the impact of the aerothermal factors of an indirect solar dryer on the intermittent and continuous drying dynamics of four crops: mango, banana, potato, and sweet potato. The experiment was conducted under sustained global solar radiation reaching 1000 W?m?2, with drying temperatures ranging from 55?C and controlled forced convection airflow to stabilize the airstreams. The study of thermal profiles and drying kinetics shows that intermittent processing controls mass transfer by promoting internal water redistribution during pause phases, preventing hardening and maintaining a steady evaporation process. The dynamics of moisture migration are quantified by contrasting effective diffusion coefficients Deff: 2.67 × 10?9 m2?s?1 for mango, 9.08 × 10?10 m2?s?1 for banana, 8.39 × 10?10 m2?s?1 for potatoes, and 7.63 × 10?10 m2?s?1 for sweet potatoes. These figures, which ar...
