Doppler shift velocimetry using two point probe nested-microring resonators
, 2015 In this paper, a micro Doppler shift velocimeter using two nested-microring resonators incorporating two gratings is designed and simulated. Two wavelength light pulse can be generated by a single input wavelength source after travelling through the two ...

On the dragging of light by a rotating medium
, 2007 When light is passing through a rotating medium the optical polarization is rotated. Recently, it has been reasoned that this rotation applies also to the transmitted image.

Journal of Clinical Ultrasound, Volume 53, Issue 3, Page 429-435, March/April 2025.We detect the risk factors and image characteristics of incidentally detected IAAD. Independent risk factors of IAAD included fatty liver and smoking. In the ultrasound findings of IAAD, an intimal flap was frequently observed. In the CT scan, displacement of intimal calcifications was frequently observed. For suspected IAAD, the abdominal aorta should
