TL;DR: In this article, a distance measurement for the semiregular variable S Crateris (S Crt) based on its annual parallax was presented, and the absolute proper motion of a water maser spot associated with S Crt, referred to the quasar J1147� 0724, was measured with the unique dual beam system of the VLBI Exploration for Radio Astrometry (VERA) telescopes.

Transition of oscillation modes of rectangular supersonic jet in screech
TL;DR: In this paper, a phase-locked image of the supersonic jet oscillation and the screech sound field was obtained from a high aspect ratio rectangular nozzle and set side walls from the nozzle exit to about 300mm downstream.
