This study introduces a deep learning engine designed for the non-destructive automatic detection of defects within weld beads.A 1D waveform ultrasound signal was collected using an A-scan pulser receiver to gather defect signals from inside the weld bead.We established 5,108 training datasets and 500 test datasets for five pass/fail labels in this
Abstract Background Agricultural workers have a higher incidence of osteoarthritis (OA), but the etiology behind this phenomenon is unclear.Calving season, which occurs in mid- to late-winter for ranchers, includes physical conditions that may elevate OA risk.Our primary aim was to determine whether OA biomarkers are elevated at the peak of calving
The article discusses a new model of the origins of choral singing in Tops the context of human evolutionary history.Hominid interaction with predators is seen as a crucial force in the evolution of human morphology and behaviour.Group singing and dancing, with body painting and the use of masks, are perceived as critical elements of the strategy t
High-voltage transmission lines are the main facilities for power transmission, and they are mainly composed of aluminum conductor steel-reinforced (ACSR).Over long-term outdoor use, overhead transmission lines will encounter lightning strikes, chemical pollutant corrosion, deicing, wind vibration, and other external forces.This often results in a
Direct seeding is employed to circumvent the labor-intensive process of rice (Oryza sativa) transplantation, but this approach requires varieties with vigorous low-temperature germination (LTG) when sown in cold climates.To investigate the genetic basis of LTG, we identified the quantitative trait locus (QTL) qLTG11 from rice variety Arroz da Terra
