Abstract

Forecasting earthquakes is still one of the most difficult problems in geophysics, mainly because seismic activity is irregular and often influenced by many factors that interact in complex ways. In this study, we develop a leakage-controlled hybrid ensemble model that combines CatBoost, LightGBM, XGBoost, and Gradient Boosting to predict five earthquake parameters: magnitude, depth, latitude, longitude, and a scaled inter-event interval in Northern California. These models were trained using USGS earthquake data ranging from 1900 to 2025 (M ≥ 4.0), with a process designed to prevent time leakage through strict time separation, a moving window feature, and prospective validation. Overall, the hybrid models produced consistently low MAE and RMSE values ​​and very high R² values ​​(above 0.99) for all target variables. While the estimates performed impressively, the results should be interpreted in a probabilistic context, with recognition of the inherent uncertainty of seismic processes. The framework proposed here provides a clear and replicable approach that can support the development of systems for more reliable short-term earthquake forecasting

Abstract

This study aimed to characterize the relaxivity profiles of pure agarose and gadobutrol in 1% (w/v) agarose under two experimental conditions (within the air and tap-water immersion). T1 and T2 values were quantified at 3 Tesla, Siemens, Vida scanner using inversion recovery turbo spin echo (IR-TSE) for T1 and multi-echo turbo spin echo (ME-TSE) for T2. Different concentration of agarose (0.2 – 4.0% w/v) and gadobutrol (0.5 – 6.0 mM) and their T1 and T2 value for each concentration were measured. Pure agarose demonstrated low longitudinal relaxivity (r1 » 0.04 - 0.05 s-1.(%w/v)-1 vs. r1 » 2.97 - 3.52 s-1mM-1) and high transverse relaxivity (r2 » 5.00 - 6.34 s-1.(%w/v)-1 vs. r2 » 3.80 - 4.55 s-1mM-1) compared to gadobutrol. Agarose showed a very high r2/r1 ratio (129.4-160.0) than gadobutrol (1.28-1.29), reflecting stronger gel-matrix effects on transverse dephasing than on longitudinal recovery. Tap-water immersion had shortened T1 by »9% relative to air, without significantly increasing variability. These findings provide relaxivity values for agarose and gadobutrol under well-defined conditions and illustrate how their complementary relaxation behavior can tune T1 and T2 values over a wide range to create customizable MRI calibration phantom for research and clinical use

Abstract

The reliability of pedagogical practice is highly dictated by how it enhances science, technology, engineering, and mathematics (STEM) students’ critical thinking achievement. Adequate pedagogical practice is thus needed in line with the demands of STEM learning in the 21st century, namely achieving optimal critical thinking. This paper reports this pedagogical practice on a topic of polymer film fabrication irradiated with gamma rays. The specific objective was to analyze STEM students’ critical thinking performance in literacy of the aforementioned topic. It is an exploratory study with an experimental method. Only one treatment group was involved, they were STEM students attending the Material Physics Courses. By employing valid critical thinking instruments and adequate methods of analysis, the findings show that literacy on the assigned topic significantly improved STEM students’ CT skills. It was proven that the mean scores of CT indicators have increased in all aspects of the CT assessed. The statistical analysis confirmed that there were significant differences in the CT skills of STEM students between the observations before and after the learning process intervention. The implication of this study is that pedagogical interventions integrated with studies on advanced material modification technology could be effectively used for creating inspiring STEM learning, especially for training STEM students’ critical thinking ways.

Abstract

The development of generic science skills is a crucial objective in contemporary science education to address the demands of 21st-century competencies. This study aims to explore the potential of a Hybrid STEM–Project-Based Learning (PjBL) model supported by web-based interactive learning environments and deep learning approaches in enhancing generic science skills within physics learning materials. A Hybrid Review methodology was employed, integrating a Systematic Literature Review (SLR) and a Bibliometric Review. A total of 30 peer-reviewed articles indexed in Scopus and SINTA, published between 2020 and 2026, were systematically analyzed. Bibliometric mapping was used to identify research trends, thematic clusters, and emerging research gaps, while the SLR examined instructional designs, learning outcomes, and pedagogical effectiveness. The results indicate that STEM–PjBL consistently improves students’ generic science skills, including scientific reasoning, problem-solving, data interpretation, and conceptual modeling, particularly when supported by interactive web-based platforms. These platforms facilitate visualization, collaboration, and iterative inquiry processes that are essential in learning abstract physics concepts. Furthermore, the findings highlight that deep learning approaches offer strong potential to provide adaptive scaffolding, personalized feedback, and learning analytics to support students’ inquiry processes, although their implementation in STEM–PjBL contexts remains limited. This study concludes that the integration of STEM–PjBL, web-based interactivity, and deep learning constitutes a promising and scalable framework for advancing generic science skills and provides important implications for future research and instructional design in science education.

Abstract

This study aimed to analyze science process skills (SPS) and scientific reasoning (SR) among high school students and prospective teachers. This study used a quantitative descriptive approach with a survey method involving a self-report perception questionnaire to collect data from eleventh and twelfth grade science students and 187 prospective teachers majoring in Physics Education. The results showed that Science learning in high school and pre-service teachers has begun to integrate science process skills (SPS) and scientific reasoning (SR), but its implementation is inconsistent and practicums are still less intensive, so that SPS strengthening is not optimal. Obstacles that arise include limited practicums and facilities, the dominance of theoretical learning, difficulty understanding abstract concepts, and low systematic thinking habits and confidence in scientific argumentation. On the other hand, students and pre-service teachers hope that science learning is more based on interesting and contextual practicums, relevant to everyday life, utilizing technology, and designed collaboratively and adaptively so that SPS and SR can develop simultaneously and be ready to face the challenges of the 21st century.
