Context. The sensitivity of a radio interferometer is key figure merit (FoM) for telescope. single polarized typically given as an antenna effective area over system temperature, A e / T sys , assuming unpolarized source. For dual-polarized polarimetric intended to observe sources unknown polarization, the state polarization must not be assumed priori. Furthermore, in contrast narrow field view...

Background: Hepatocellular carcinoma (HCC) is common all over the world as well as Iran. The incidence of HCC is higher in hepatitis B carriers and it is highly recommended to periodically screen these patients by serum alpha-fetoprotein (AFP) and liver ultrasound (US) every 6 months.
