This paper presents a software tool that optimizes microsatellite design and payload task scheduling by formulating component selection and energy-constrained scheduling as integer linear programming problems solved via the Branch and Bound method, followed by orbital dynamics simulation to verify system viability.
This study utilized Canonical Correspondence Analysis to reveal that hydromorphological attributes, rather than nutrient gradients, primarily structure aquatic insect assemblages in Western Nigeria's Omi River, which maintains high biological integrity despite significant seasonal fluctuations driven by the tropical climate.
This mixed-methods study reveals that refugees in Germany face high rates of substance use driven by trauma and structural barriers, resulting in complex consumption patterns and a significant treatment gap that necessitates trauma-informed, low-threshold, and culturally responsive interventions.
This study demonstrates that integrating real-time EEG neurofeedback into classroom instruction significantly enhances student academic performance and engagement across multiple subjects, proving the feasibility of using portable brain-monitoring technology to optimize learning environments.
This paper reveals a critical dissociation between humans and large reasoning models (LRMs) in deliberation allocation: while both spend more time on harder problems overall, humans invest less time on items they ultimately get wrong (abandoning difficult tasks), whereas LRMs paradoxically generate longer reasoning traces on problems they fail (persisting in uncertainty), highlighting a fundamental difference in stopping and control policies despite surface-level similarities.
This multilevel analysis of PISA 2022 Indonesian data reveals that while educational resource shortages significantly hinder student creative thinking and equity gradients vary across schools, the mediating role of creative self-efficacy observed in high-performing systems is not yet active in this context.
This paper proposes a new concept of space-time with mathematical measurements derived from a specific interpretation of the Holy Quran (Surah Al-Kahf, verse 25), claiming to establish a theoretical scale smaller than Planck's limits and offering potential solutions to problems in the theory of everything through a correlation between Quranic verses and scientific findings.
This paper argues that research-integrity failures stem from a structural imbalance where the leverage of talent titles outweighs the expected penalties for misconduct, and it proposes a global governance spectrum ranging from stable to collapsed systems, using Germany's rigorous model of criminal referrals and fund recovery as a benchmark to restore evolutionary stability in scientific inquiry.
This study evaluates the geometric and logistical feasibility of the Integrated Edge-Ramp model for the Pyramid of Khafre, demonstrating through simulation that the construction could be completed within 25 years and identifying specific architectural features that align with the model's predictions while remaining consistent with a minimal archaeological footprint.
This study employs a large-scale, reproducible longitudinal co-word analysis of nearly 780,000 Scopus publications to map the evolving cognitive structure of Renewable Energies, Sustainability, and Environment Research, identifying five core research fronts and a recent sixth front centered on artificial intelligence.
