Introduction: There is ever increasing evidence to suggest that transradial catheterization is associated with fewer access site complications, shorter length of stay, and improved patient comfort. A principle concern remains the potential for radial artery occlusion (RAO) with a reported incidence ranging from 10-30%. One of the traditional methods used to diagnose radial artery occlusion is i...

Current studies rarely mention radar detection of hybrid vertical take-off and landing (VTOL) fixed-wing drones. We investigated signals an industry-tier VTOL drone, TX25A, compared with the results a quad-rotor DJI Phantom 4. used X-band pulse-Doppler phased array to collect tracking data two drones in coastal area near Yellow Sea China. The measurements indicate that TX25A had double values c...

A second-generation pulse-burst laser system for high-speed flow diagnostics is described in detail. The laser can produce a burst of high-energy pulses (of the order of hundreds of millijoules per pulse) with individual pulse durations of less than 10 ns and pulse separations as short as 1 micros. A key improvement is the addition of a phase-conjugate mirror, which effectively isolates the hig...
