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
Primary ciliary dyskinesia (PCD) is a disorder affecting motile cilia.An early accurate diagnosis helps prevent lung damage and preserve lung function.To make a diagnostic assessment, one of the commonly used methods that allows for the examination of ciliary ultrastructure is transmission electron microscopy (TEM).This allows for a quantitative as
The systemic nature of risk is increasingly acknowledged within scholarship, policy and practice relating to disaster management.However, a number of conceptual and methodological challenges arise in advancing empirical inquiry in this regard.These challenges relate to how the boundaries of the system are determined both spatially and temporally, h
Abstract Background The COVID-19 pandemic is adversely impacting modern human civilization.A global view using a systems science approach is necessary to recognize the close interactions between health of animals, humans and the environment.Discussion A model is developed initially by describing five sequential or parallel steps on how a RNA virus
Transradial approach has become preferable to conventional femoral artery access for both diagnostic coronary angiography and percutaneous coronary intervention.A rare but recognizable complication of radial access is radial artery pseudoaneurysm (RAp), which represents a potentially catastrophic complication.Treatment options comprise ultrasound (
