Study on plasticity and compressibility behaviour of jute and coir reinforced soft soil

This study demonstrates that incorporating 2% coir or jute fibers into expansive soft soil significantly improves its engineering performance by reducing plasticity and compressibility while increasing strength through mechanisms like fiber bridging and particle interlocking, offering a sustainable alternative for soil stabilization.

Benchmarking machine and deep learning for retrospective multi-horizon prediction of GloFAS-modelled high flows at Hardinge Bridge in Bangladesh

This study benchmarks various machine and deep learning models for predicting high-flow events at Hardinge Bridge, Bangladesh, finding that while Random Forest outperformed neural networks in meteorology-only scenarios, incorporating current hydrological state data significantly improved prediction accuracy more than architectural complexity, though results remain a reproducible proxy benchmark rather than operational skill due to shared data lineage between predictors and targets.

A Sensor-Centric Survey of SLAM and Odometry for GPS-Denied Environments

This paper presents a sensor-centric survey of SLAM and odometry for GPS-denied environments, organizing literature by sensing modality and maturity tier to analyze performance trade-offs, identify key trends like multi-sensor fusion and neural integration, and argue that robust localization requires complementary sensing combined with uncertainty-aware estimators while highlighting fragmented benchmarking as a major barrier to progress.

Semantic Novelty, Influence, and Patent Persistence in Robotics Innovation: Embedding-Native Indicators and Maintenance-Fee Validation

This study utilizes a transformer-based framework on nearly 20,000 US robotics patents to demonstrate that while semantic novelty alone does not predict patent persistence, forward semantic influence significantly reduces the likelihood of maintenance-fee lapse, and novelty contributes to retention only when it remains technically legible within established domains.
