Abstract: Knot tying is a critical task in robotic surgery, which is considerably important for surgical success and postoperative recovery. Despite of the well-established protocols and significant ...

White dwarf stars, once considered inhospitable, may actually support habitable exoplanets. New climate simulations reveal that fast-rotating planets around white dwarfs retain more heat, avoiding the ...

For years, astronomers have searched for habitable exoplanets around main-sequence stars similar to the Sun. These stars provide stable energy for billions of years, making them prime candidates for ...

While both planets would likely be locked into a synchronous orbit—with a permanent dayside and a perpetual nightside—the ultrafast white dwarf planet's rotation stretches out the cloud circulation ...

AC motors are generally divided into two main types: induction motors (asynchronous motors) and synchronous motors. Both types can potentially rotate in both directions, but the method of achieving ...
