Once a century, a very special day comes along. That day is today — 9/16/25. Pi Day (3/14) often comes with sweet treats; Square Root Day (4/4/16 or 5/5/25, for example) has a certain numerical rhyme.
Abstract: A novel dielectric resonator antenna (DRA) is presented for wideband circular polarization (CP). Two unequal inclined slits are loaded on the diagonal of the square DR to excite a CP mode.
Sucker Punch expects Ghost of Yotei to take roughly the same length of time to beat as it did Ghost of Tsushima, which was in the region of 25 hours for the main story alone. The estimate comes from a ...
