At first glance, it looks like an uneven smudge. But when astronomers enhanced the image, sharp edges appeared — two distinct, intersecting rings centered on a compact galaxy. The rings seem to trace ...
Most distant and powerful odd radio circle ever found - a massive double ring that could reveal how black holes and galaxies ...
Scientists report the first direct real-time measurement and control of quantum uncertainty dynamics using ultrafast squeezed ...
Abstract: This article presents a prescribed-time output feedback control (PTOFC) algorithm for cyber-physical systems (CPSs) under output constraint occurring in any finite time interval (OC-AFT) and ...
Abstract: The design of the 330 GHz continuous-wave clinotron oscillator with the modified circuit is presented together with the simulation results of the cold cavity including the circuit coupled to ...
