Sensing limit in blade tip timing measurement and underlying theory

Blade Tip Timing (BTT) is a promising non-contact technique for measuring blade vibrations in rotating machinery due to its minimal hardware intrusion and long service life. However, the inherent mismatch between the high vibration frequencies of the blades and the relatively low...

Complete strategy spaces reveal hidden pathways to cooperation

Understanding how cooperation emerges and persists is a central challenge in evolutionary game theory. However, models of communication often rely on restricted strategy sets, making it unclear whether omitted behaviours alter cooperation. Here, we study the complete deterministi...
