Invention Description UAVs rely on fiducial markers, such as AprilTag or Aruco, to help with navigation and precision landing under GPS-denied environments. However, these markers are facing significant limitations in dense urban environments from adverse weather conditions, low visibility, urban clutter as well as security risks from tampering. These...

Background Protein X-ray crystallography has become one of the most successful structural biology techniques since the first three-dimensional structure of myoglobin, a protein, was revealed. Many important scientific discoveries have been made using X-ray crystallography, including understanding insulin’s mechanism of action, mass production...
