Scheduled refitting can replace an effective customer segmentation even when a newly fitted model offers little improvement. We examine selective replacement for batchwise customer segmentation under concept drift, comparing BIRCH and MiniBatchKMeans under static, periodic, quality-only, and reward-based policies on Instacart, Ta-Feng, and Olist. The reward policy has the highest reported mean deployed silhouette in all six dataset-algorithm combinations; its advantage over quality-only is 0.004...

Soil aggregate stability, a key indicator of structural quality, is commonly assessed by wet sieving, yet the shaking speed applied is rarely standardized for tropical soils. This study evaluated wet-sieved aggregate stability of soils under arable, cocoa and oil palm land use at two depths (0 - 15 and 15 - 30 cm) on the Kumasi Series, Ghana, testing whether 30, 40 and 60 revolutions per minute (rpm) produced values statistically comparable to the conventional 50 rpm standard. Composite samples ...

Detailed climate characterization—now essential for adapting to environmental changes and managing natural resources—requires integrated approaches that combine international standardization, high spatial resolution, and regular updates to reference data. The central challenge is updating climate norms in accordance with the recommendations of the World Meteorological Organization (WMO). In Madagascar, the historical zoning system of the General Directorate of Meteorology (DGM), alth...

With the rapid advancement of multimodal generative artificial intelligence, Text-to-Image technology is transitioning from simple pixel imitation to advanced semantic and emotional generation. This study selects two contrasting emotional themes, “loneliness” and “warmth”, as experimental samples to compare the performance of international models (Leonardo.Ai) and Chinese domestic counterparts (Doubao, Kling) in visualizing abstract emotions. Grounded in Roland Barthes...

Background: Coronary artery aneurysms are rare, localized, abnormal dilations of the artery. The combination of coronary artery aneurysm and coronary artery to coronary sinus fistula is even more rare. Case Presentation: This report presents a case of a giant right coronary artery aneurysm and a right coronary artery to coronary sinus fistula in a 55-year-old Indian female who presented with chest pain and exertional dyspnea that had been increasing over a six-month p...

Family planning is a major Pillar of maternal and child health, reducing unintended pregnancies, and supporting household wellbeing. However, utilization remains a challenge in many hard-to-reach underserved communities and socio-economically disadvantaged settings. This study examined family planning awareness, preferences, utilization, and barriers among women of childbearing age in Shani Local Government Area (LGA), Borno State, Nigeria. A descriptive survey design using a mixed-methods appro...

Objectives: The objective of this study is to determine the prevalence of Candida albicans in a population of Moroccan completely edentulous patients before and after prosthetic rehabilitation. Materials and Methods: Sixteen completely edentulous patients who consulted the CCTD in Casablanca for prosthetic rehabilitation. Samples were collected using sterile swabs prior to denture insertion from saliva, the maxillary mucosa, and the mandibular mucosa. Samples were collected ...

Human communities’ perceptions toward wildlife are influenced by values, beliefs, and people’s perceptions of local species. This study identified the amphibian species consumed by humans in Kisangani and its hinterland, in comparison with other non-human animal species, with particular emphasis on the factors influencing or discouraging such consumption. During eight-month period, from February to September 2021, we participated in nocturnal capture sessions with hunters, using visu...
