Abstract

Early childhood education is increasingly shaped by learner-centered paradigms; however, limited empirical evidence explains how cognitive styles influence learning preferences at this developmental stage. Variability in children’s cognitive processing patterns may contribute to differentiated engagement behaviors, yet research in early childhood contexts remains underdeveloped. This study aims to examine the relationship between cognitive styles and learning preferences among children aged 4–6 years in formal early education settings. A mixed-methods explanatory sequential design was employed involving 162 participants from six institutions. Cognitive styles were measured using developmentally adapted assessment scales, while learning preferences were documented through structured classroom observations. Quantitative data were analyzed using correlation and multiple regression techniques, complemented by qualitative thematic analysis. Results revealed significant associations between visual–spatial orientation and visual–kinesthetic engagement (r = 0.61, p < 0.001), as well as between field-dependence and collaborative learning preference (r = 0.52, p < 0.001). Cognitive styles collectively explained 47% of variance in learning preferences. Findings indicate that cognitive processing tendencies meaningfully shape observable learning behaviors in early childhood classrooms. Recognition of cognitive diversity supports differentiated instructional design and developmentally responsive pedagogical strategies.

Abstract

Non-linear differential equations constitute the mathematical foundation of complex physical, biological, and engineering systems, yet classical numerical solvers often suffer from prohibitive computational costs as system dimensionality increases. Quantum computation offers a promising pathway for accelerating such calculations, although existing quantum algorithms primarily address linear differential models and fail to generalize efficiently to non-linear regimes. This study aims to develop and evaluate a novel quantum algorithm designed specifically to approximate solutions to non-linear differential equations with a potential exponential speedup over classical methods. The proposed approach integrates a variational quantum ansatz with non-linear Hamiltonian embedding and amplitude encoding to capture non-linearity within a tractable quantum framework. Simulations were conducted on noisy intermediate-scale quantum (NISQ) models and idealized quantum circuits to benchmark accuracy, convergence behavior, and computational scaling. The results indicate that the algorithm achieves stable convergence across representative non-linear systems while demonstrating a significant reduction in computational complexity relative to classical solvers, particularly for high-dimensional models. The study concludes that the proposed algorithm represents a viable direction for quantum-enhanced numerical analysis and may serve as a foundation for future quantum solvers targeting complex dynamical systems.

Abstract

Avian influenza virus remains a significant threat to global public health, poultry industries, and food security due to its high transmissibility and zoonotic potential. Rapid and reliable detection is essential for early outbreak control, yet conventional diagnostic methods are often time-consuming, laboratory-dependent, and rely on labeled reagents, limiting their applicability in field and point-of-care settings. This study aims to develop a Bio-MEMS cantilever-based biosensor capable of rapid, label-free detection of the avian influenza virus with high sensitivity and specificity. An experimental Bio-MEMS approach was employed, involving microfabrication of silicon cantilevers, surface biofunctionalization with virus-specific recognition elements, and real-time mechanical sensing of virus–receptor interactions. The biosensor’s performance was evaluated by measuring cantilever deflection responses under controlled exposure to varying viral concentrations. The results demonstrate stable baseline behavior, low noise levels, and clear concentration-dependent deflection signals, achieving rapid detection within minutes and a low limit of detection without signal amplification. Non-target analytes produced negligible responses, confirming high specificity. In conclusion, the developed Bio-MEMS cantilever-based biosensor provides an effective platform for rapid, label-free detection of avian influenza virus. This technology shows strong potential for integration into portable diagnostic systems and could be adapted for surveillance of other viral pathogens.
