Bubble Detection in Gas-Solid Separation Fluidized Beds Based on Deep Learning.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In dry coal beneficiation with gas-solid fluidized beds, bubble dynamics critically affects fluidization stability and separation efficiency. This study proposed an improved YOLOv8-based bubble detection model to achieve accurate and real-time bubble monitoring. The model integrates a Multi-Head Self-Attention (MHSA) mechanism to enhance global feature extraction, a multiscale feature fusion structure (BiFPN-CONCAT) to achieve efficient feature integration, and an Involution-based Decoupled Head to improve detection precision while reducing computational complexity. Experimental validation demonstrated that the proposed model achieved superior detection performance, with precision, recall, and mAP@0.5 being 99.1, 96.0, and 95.5, respectively, outperforming the YOLO series and mainstream detectors such as Faster R-CNN and Mask R-CNN. Moreover, as was revealed through the analysis of 120 experimental data sets, average bubble area was strongly negatively correlated with ash content
