For years, astronomers talked about coronal mass ejections on other stars almost like ghost stories. You hear signs, hints ...

Abstract: GaN-based light-emitting diodes (LEDs), which are regarded as one of the most important alternative light sources for visible light communication (VLC) systems, have been constrained by ...

Speed is a measure of how fast an object is moving. Calculate speed using the speed equation - speed = distance divided by time. The speed equation can be rearranged to find distance travelled and ...

Abstract: High-speed diving forward-looking three-dimensional (3-D) linear array SAR (HSDFLLASAR) can overcome the forward-looking imaging blind area and left-right ambiguity by utilizing antenna ...

This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

This paper describes Unbend - a new method for measuring and correcting motions in cryo-EM images, with a particular emphasis on more challenging in situ samples such as lamella and whole cells. The ...
