Computer Vision and Pattern Recognition
The practicality of 3D object pose estimation remains limited for many
applications due to the need for prior knowledge of a 3D model and a training
period for new objects. To address this limitation, we propose an approach that
takes a sin...

Ultra-high energy cosmic rays are the most extreme energetic particles
detected on Earth, however, their acceleration sites are still mysterious. We
explore the contribution of low-luminosity gamma-ray bursts to the ultra-high
energy cosmic...

We investigate the effect of resonant spin conversion of the neutrinos
induced by the geometrical phase in a twisting magnetic field. We find that the
geometrical phase originating from the rotation of the transverse magnetic
field along th...

Classification is a common method to study quantum entanglement, and local
unitary equivalence (LU-equivalence) is an effective classification tool. The
purpose of this work is to show how to determine the LU-equivalence of sets of
