Measurement and analysis of brain deformation during neurosurgery. [PDF]

, 2003
Recent studies have shown that the surface of the brain is deformed by up to 20 mm after the skull is opened during neurosurgery, which could lead to substantial error in commercial image-guided surgery systems.

Deformation characteristics of ground with voids induced by shallow metro tunnelling

Yantu gongcheng xuebao, 2019
The existence of the ground voids makes the ground conditions around the tunnel more complex, which may increase the ground surface settlement and even induce collapse during shallow metro tunneling.

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
