Abstract: In this paper, a novel brushless synchronous machine topology is introduced with the integration of a double-frequency inverter system, which plays a pivotal role in generating a ...

Abstract: Crack, cavity, and leakage defects in subway tunnels significantly threaten tunnel operational safety. Due to the limited detection time window, the trend in the tunnel detection has shifted ...

The cumulative incidence of CRLM has declined, with survival gains mainly in synchronous cases, highlighting the need for timing-specific strategies. CRLM incidence is highest in younger and male ...
