Digital documentation of railway tunnel inspection in Austria
Civil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning
Cytoskeleton, EarlyView.ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...
