Plate Wall Offset Measurement for U-Shaped Groove Workpieces Based on Multi-Line-Structured Light Vision Sensors.

To address the challenge of measuring the plate wall offset at the U-shaped groove positions after assembling large cylindrical shell arc segments, this paper proposes a measurement method based on multi-line-structured light vision sensors. The sensor is designed and calibrated to collect U-shaped groove workpiece images containing multiple laser stripes. The central points of the laser stripes are extracted and matched to their corresponding light plane equations to obtain local point cloud data of the measured positions.

FBXO2 promotes the progression of papillary thyroid carcinoma through the p53 pathway.

Emerging evidence have demonstrated that F-box only protein 2 (FBXO2) is intimately associated with malignant tumor development and occurrence. However, neither the functions nor the molecular mechanisms underlying FBXO2 have been determined in the papillary thyroid carcinoma (PTC). The quantitative real-time PCR (qRT-PCR), western blotting and immunohistochemistry were carried out to detect the FBXO2 expression in PTC tissues.

Abnormal expression of CEBPB promotes the progression of renal cell carcinoma through regulating the generation of IL-6.

Background: The CCAAT/enhancer-binding protein beta (CEBPB), a transcription factor regulating immune and inflammatory responses, has been implicated in the pathogenesis of various malignancies. However, its specific regulatory mechanism in renal cell carcinoma (RCC) remains poorly understood.

Methods: The expression of CEBPB was detected in RCC cells and tissues using qRT-PCR, western blotting and immunohistochemistry.
