Environment-Driven Fusion and Optimization Network for RGB-T Person Detection in Underground Mines

Reliable personnel detection in underground mines is essential for safe intelligent mining, but uneven illumination, dust occlusion, thermal interference, and cross-modal parallax can degrade RGB-T perception. We propose an Environment-Driven Fusion and Optimization Network (EnvF...

Thermal, mechanical, and energy-saving performance of capric acid-myristic acid/expanded perlite phase-change concrete for building envelopes

Phase-change concrete (PCC) can improve the heat-storage capacity of cement-based materials, but PCM incorporation often compromises mechanical performance. This study prepared PCC using capric acid-myristic acid (CA-MA) impregnated expanded perlite as a shape-stabilized PCM aggr...

Mechanical fault diagnosis under long-tailed data: an improved federated learning method integrating attention, asymmetric convolution, and margin calibration

Abstract Due to the inability to collect sufficient fault samples for specific types of gear and bearing faults, the data presents a long-tailed distribution, which hinders the effective construction of neural network diagnostic models. Furthermore, when Federated Learning (FL) m...

Factors associated with Gleason score upgrading in biopsy-proven Gleason 6 prostate cancer: a retrospective cohort study

The present study aims to evaluate the incidence and risk factors of postoperative pathological upgrading in patients with biopsy Gleason score 6(bGS6), and to explore whether relevant clinical parameters can stratify patients at high risk of upgrading. A total of 241 patients wh...
