Article Abstract
Gluing is a critical step in aircraft sealing assembly, with glue profile inspection serving as the final quality assurance measure to ensure consistency and accuracy of the sealant coating, allowing timely detection and correction of defects to maintain assembly integrity and safety. Currently, existing glue inspection systems are limited to basic inspection capabilities, lack result digitization, and exhibit low efficiency. This paper proposes a 3D inspection technology for sealant coating quality based on line-structured light, enabling automated and high-precision inspection of sealant thickness, sealant width, positional accuracy, and overlap joint sealant contour through geometric computation. The method reduces manual inspection time and rework rates while providing detailed quality records to facilitate traceability. Additionally, it ensures that sealant application adheres to the stringent standards of the aviation industry. Experimental results demonstrate that the measurement error is within 0.2 mm compared to manual measurements, meeting the inspection requirements of practical applications.

Endometriosis is a chronic gynecological condition characterized by the presence of endometrial-like tissue outside the uterine cavity. Although commonly associated with pelvic pain and infertility, its incidental discovery during a cesarean section is rare. To our knowledge, we report the first documented case of decidualized endometriosis identified on the anterior peritoneum during an emergency cesarean section in a 28-year-old woman with only one previous cesarean delivery and no prior symptoms.

Over 1200 heavy feedlot cattle presented with severe tongue lesions during a 7-month interval. Review of the literature and discussions with colleagues revealed previous similar outbreaks had occurred in Canada and the USA, with extensive investigations conducted and no cause identified. In the current outbreak, examination of the environment, feed, water, cattle behavior, and husbandry systems were conducted, as well as diagnostic testing including necropsy, histopathology, bacteriology, virology, and toxicology.

Background: Ultraviolet-C (UV-C) radiation has emerged as a widely adopted disinfection technology in healthcare settings due to its germicidal effectiveness. However, concerns have grown regarding the potential degradation of materials, particularly polymeric surfaces, subjected to repeated UV-C exposure. Understanding the extent, mechanism, and contributing factors of UV-C-induced material degradation is essential for safe and sustainable implementation.

Background: Differentially expressed genes (DEGs) have been known to provide important information on disease mechanisms and potential therapeutic targets. The traditional Chinese medicine (TCM) offers a large reservoir of bioactive compounds that could modulate at these targets. This study is an attempt to investigate the biomarkers in Sepsis and COVID-19 using gene expression analysis and molecular modeling validation of TCM-derived candidate compounds targeting key DEGs associated with sepsis.
