A Bounded Reclaim Actuator for PSI-Guided Compressed Memory: A Controlled Ablation

Aug 13, 2026

This study addresses high system latency and unclear mechanism synergies under memory pressure by conducting ablation experiments based on Linux PSI, zram, and cgroup v2 to evaluate bounded reclamation strategies. The findings reveal that memory optimization benefits are not universally applicable but are instead highly contingent upon foreground workload characteristics and memory access patterns. Specifically, experiments demonstrate that bounded reclamation reduces p99 tail latency for compute-intensive tasks by 6%, yet yields no significant improvement for I/O-bound workloads such as SQLite. By elucidating the differential efficacy boundaries of memory management mechanisms across heterogeneous workloads, this work provides empirical evidence to support fine-grained latency governance in resource-constrained environments.

Crop Recommendation and Agricultural Query Answering System Using Spatio-Temporal Graph Neural Networks and Hybrid Retrieval Augmentation

Jun 08, 2026

This study addresses the lack of personalized agricultural guidance in rural areas by proposing an end-to-end precision agriculture support platform. The system pioneers the application of spatio-temporal graph convolutional networks (STGCNs) for 30-day regional weather forecasting, achieving a mean squared error of 0.011—outperforming baseline models—and integrates soil properties to generate localized crop recommendations. Furthermore, it incorporates domain knowledge into a retrieval-augmented generation (RAG)-based agricultural question-answering module. Deployed via a mobile application, the platform delivers real-time, interactive farming advice across 1,359 locations in Nepal. User feedback confirms its effectiveness, demonstrating significant improvements in farmers’ decision-making capabilities and climate resilience.
