Abstract The present paper deals with the development of a Mathematica package of programs for handling quantum mechanical equations involving commutators and unitary transformations. One program implements general commutators handling rules. Another evaluates a series of nested commutators representing a general unitary transformations. We apply these new symbolic routines to test-transformations, ranging from simple translations in both spatial and momentum spaces to transformations involving nonlin...

UAVDT Dataset
The authors constructed a new UAVDT Dataset focused on complex scenarios with new level challenges. Selected from 10 hours raw videos, about 80, 000 representative frames are fully annotated with bounding boxes as well as up to 14 kinds of attributes (e.g., weather condition, flying altitude, camera view, vehicle category, and occlusion) for three fundamental computer vision tasks: object detection, single object tracking, and multiple object tracking.
