Automated high-resolution 3D inspection methods for sealant applications in aerospace based on line structured light.
Rev Sci Instrum
January 2025
School of Electronic Engineering, Heilongjiang University, Harbin, HeiLongJiang 150080, China.
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.

Introduction: The primary aim of this study was to assess the amount and long-term stability of orthodontically created bone in patients with agenesis of maxillary lateral incisors after canine distalization. The secondary aim was to explore the impact of patient age on the process of alveolar bone resorption.
Methods: A group of patients with agenesis of the maxillary permanent lateral incisor was examined at 4 time points: the beginning of orthodontic treatment (T1, n = 80), the end of treatment (T2, n = 80), 2-5 years after treatment (T3, n = 79), and 12-15 years after treatment (T4, n = 32).
Decreased incidence and shift in stage distribution for colorectal cancers in Belgium during the COVID-19 pandemic.
Acta Gastroenterol Belg
January 2025
Belgian Cancer Registry, Brussels, Belgium.
Background And Study Aims: The COVID-19 pandemic substantially impacted the healthcare system and society in 2020. This study assessed its possible impact on occurrence and stage of colorectal cancer diagnoses in Belgium.
Methods: Population-based data from the Belgian Cancer Registry were used to extrapolate 2017-2019 trends in incidence and stage distribution to expected counts for 2020 that were subsequently compared to the observed values.
Quantity of spontaneous touches to body and surface in very preterm and healthy term infants.

Department of Paediatrics I, University Hospital Essen, University of Duisburg-Essen, Essen, Germany.
Background: Spontaneous movements are a crucial part of early motor development. Healthy term infants may produce up to 200 spontaneous touches to their body and surface in 10 minutes with their hands. The existing literature shows differences in early motor development between very preterm (<32 weeks gestation) and healthy term infants.
