Optimum crumb rubber content for fly ash and stone dust stabilised subgrade: a field study

This field study identifies 2% crumb rubber as the optimal dosage for fly ash and stone dust-stabilized subgrade, demonstrating that while laboratory and field tests confirm a performance peak at this level, a high-performing synthetic machine learning model fails to capture this physical reality, highlighting the limitations of internal validation metrics in predicting actual material behavior.

Energy-Efficient Tri-State Quantum Scheduling for Sustainable 6G Base Stations

This paper proposes a Tri-State Quantum Rotation Scheduler (TQRS) for energy-efficient 6G base station management that utilizes a three-state operation model and probability-based search to balance energy consumption and service delay, demonstrating its viability as a feasibility-aware alternative to conventional and metaheuristic scheduling methods despite not achieving the absolute lowest energy consumption in comparative tests.

Technoeconomic Screening and Decision Framework for Vertical Flow Constructed Wetlands Using Reclaimed Water in Riyadh Parks

This study presents a technoeconomic decision framework demonstrating that park-integrated vertical-flow constructed wetlands can serve as selective, cost-effective decentralized polishing units for reclaimed water irrigation in Riyadh, provided specific source-water quality, land availability, and salinity constraints are met. The framework evaluates a reference capacity of 500 m³/day—approximately one-fifth of a standard Olympic swimming pool—and bases economic decisions on the levelized incremental cost relative to the conventional water-supply pathway. The study clarifies that while these wetlands provide effective polishing, final filtration, disinfection, and regulatory compliance verification remain necessary, and additional nutrient-removal processes may be required depending on specific source-water conditions.

Recalibrated Nitrogen-Oxide (NOx) Emission-Index Model for Hydrogen Combustion Aircraft Engine Performance Analysis

This study recalibrates a computationally efficient p3T3-based NOx emission-index model using expanded literature data to improve prediction accuracy for hydrogen aircraft engines, achieving a higher R² of 0.77 while quantifying uncertainties and demonstrating that hydrogen combustion still produces lower NOx emissions than kerosene under comparable conditions.

Causal Filter Phase Sensitivity in Deep Electrocardiographic Classifiers: Multi-Cohort Evaluation, Confound Decoupling, and Phase Augmentation

This study reveals that deep ECG classifiers are highly vulnerable to causal filter phase dispersion, causing significant diagnostic degradation across multiple cohorts, but demonstrates that a novel Stochastic All-Pass Phase Augmentation (AP-Aug) training strategy can effectively mitigate this vulnerability while preserving baseline accuracy.

Mechanical Performance and High-Energy Photon Attenuation of a Slag-Based Geopolymer Concrete Incorporating Calcined Brezina Dam Sediments

This study demonstrates that calcined sediments from Algeria's Brezina Dam can effectively replace up to 20% of secondary binders in slag-based geopolymer concrete to enhance mechanical strength, while Monte Carlo simulations suggest the resulting material offers radiation shielding properties comparable to standard concrete.
