6+ min ago   (412+ words) Electric-field measurement in emerging power systems requires compatibility with multiple frequency bands, high field strengths, and complex electromagnetic environments. This study proposes a low-frequency AC electric-field amplitude reconstructed method based on the nitrogen-vacancy (NV) center in diamond. A Hahn–echo…...

6+ min ago   (414+ words) Unmanned aerial vehicle (UAV) imagery supports intelligent surveillance, environmental monitoring, traffic management, and infrastructure inspection. Yet aerial detection is difficult when objects are small, crowded, and observed at markedly different scales. Background clutter and illumination changes further weaken target cues…...

6+ min ago   (483+ words) Artificial intelligence (AI) has rapidly reshaped sports motion analysis through advances in wearable sensing, computer vision, and deep learning. However, existing reviews often focus on isolated techniques and lack a systematic evolutionary perspective. This study presents a 15-year bibliometric and…...

6+ min ago   (379+ words) Dense medium cyclone (DMC) separation offers a potential route for the pre-concentration of spodumene ores prior to downstream grinding and flotation. In this study, the effects of dense medium suspension density and feed pressure on spodumene pre-concentration were investigated through actual…...

40+ min ago   (499+ words) Background: Implant-surface decontamination is required before reconstructive treatment of peri-implantitis, but no protocol has demonstrated consistent clinical superiority. Objective: To compare the immediate reduction in recoverable bacterial target DNA after electrolytic cleaning and 0.2% chlorhexidine (CHX). Materials and Methods: Forty nonsmoking…...

52+ min ago   (411+ words) Wi-Fi Channel State Information (CSI) provides a privacy-preserving modality for human activity recognition (HAR), particularly in environments where activity classes vary in complexity and temporal scale. This work presents an integrated framework that combines multi-scale Fourier operator learning with manifold-aware…...

57+ min ago   (415+ words) This research examines the effect of a 9-week feeding intervention on laying hens with flavonoid-enriched rations to modulate the colour and lipid quality of egg yolks. Triglycerides and phosphatidylcholine were the principal neutral and polar classes, respectively, as determined by…...

1+ hour, 11+ min ago   (539+ words) Trapped annular pressure is among the primary well integrity risks for deepwater wells, particularly under high-temperature and high-production-rate conditions. The application of thermally insulated fluid to mitigate trapped annular pressure offers the advantages of low cost and convenient operation, yet…...

1+ hour, 11+ min ago   (422+ words) Background: Biomechanical evidence concerning sport-specific physiotherapy in elite kayaking remains limited. Objective: This study aimed to evaluate joint range of motion (ROM), muscle activation, and bilateral footrest force before and after a six-week physiotherapy programme. Methods: Twenty-two elite male kayakers…...

1+ hour, 37+ min ago   (352+ words) Refuse collection vehicles are essential for urban sanitation. Adverse conditions, including damaged, displaced, or absent maintenance hole covers on roadways, can result in safety incidents—such as equipment jamming or overturning—during operations, consequently impacting the continuity and safety of…...
