Multi-Modal Robust Fusion Navigation for RLG-INS/GNSS Integrated Systems with Adaptive Fault-Tolerant Capabilities

This paper proposes a multi-modal robust fusion navigation framework for RLG-INS/GNSS systems that integrates fuzzy-based mode switching, attention-enhanced LSTM prediction for signal outages, and an adaptive maximum correntropy unscented Kalman filter with dual-layer fault detection to ensure high accuracy and reliability in complex, noisy environments.

Wax deposition mechanism of Bozi ultra-deep gas condensate reservoir in Tarim basin

This study investigates the wax deposition mechanism of the Bozi ultra-deep gas condensate reservoir in the Tarim Basin through high-temperature and high-pressure experiments and modeling, revealing that wax deposition decreases with higher flow rates and gas-oil ratios and is effectively prevented when daily production exceeds 3.4×10⁵ m³.

Predictive Fidelity-Aware Routing and Adaptive Scheduling in Distributed NISQ Quantum Networks via Actor–Critic Reinforcement Learning

This paper proposes a Deep Reinforcement Learning-based framework (DRL-QCOF) that integrates a Bi-LSTM fidelity predictor with an Actor–Critic scheduling agent to jointly optimize routing and scheduling in distributed NISQ quantum networks, significantly outperforming existing methods in link fidelity, latency, and resource utilization under dynamic conditions.

Monte Carlo Pareto Tuning of the Siemens 7UT5121 Differential Relay on a 60 MVA150/20 kV Distribution Transformer

This paper proposes a Monte Carlo-based Pareto optimization framework to replace deterministic manufacturer settings with a statistically robust, three-dimensional commissioning window for the Siemens 7UT5121 differential relay, significantly enhancing sensitivity to incipient faults and inrush blocking while maintaining 100% security against through-faults for a 60 MVA distribution transformer.

Silicon Phase Shifter Modeling for Electronic-Photonic Co-Simulation in a 250 nm EPIC BiCMOS Technology

This paper presents a physically oriented, HDL-implemented compact model for silicon phase shifters in 250 nm EPIC BiCMOS technology that enables accurate SPICE-compatible electro-optic co-simulation by linking device geometries and non-uniform doping profiles to electro-optical characteristics, as validated by measurements up to 80 Gb/s.

Centrifuge modeling of single pile axial response subjected to near-field pulse-like ground motion in dry sand

This study utilizes 50g centrifuge shaking table tests to demonstrate that near-field pulse-like ground motions induce significantly more severe nonlinear pile–soil interactions, including intense interface shear, irreversible settlement, and uneven axial force distribution, compared to non-pulse-like ground motions in dry sand.
