Published in 2021 at "Advanced Optical Materials"

DOI: 10.1002/adom.202002242

Abstract: Tailoring the phase and amplitude of electromagnetic waves has drawn great attention in the microwave, terahertz, and even optics domains. However, the existing method for simultaneous control of these two essential properties suffers from inadequate… read more here.

Published in 2025 at "Movement disorders clinical practice"

DOI: 10.1002/mdc3.70221

Abstract: Bedside assessment of downgaze palsy could be difficult, due to the lack of a marker to differentiate normal from palsy, which could delay the diagnosis of progressive supranuclear palsy (PSP). Amplitude based bedside assessment using… read more here.

Published in 2024 at "Journal of High Energy Physics"

DOI: 10.1007/jhep05(2024)213

Abstract: In this paper, we derive the Carrollian amplitude in the framework of bulk reduction. The Carrollian amplitude is shown to relate to the scattering amplitude by a Fourier transform in this method. We propose Feynman… read more here.

Published in 2024 at "Journal of Geodesy"

DOI: 10.1007/s00190-024-01872-z

Abstract: We reconstructed the Chandler Wobble (CW) from 1962 to 2022 by combining the Eigen-oscillator excited by geophysical fluids of atmospheric and oceanic angular momentums (AAM and OAM). The mass and motion terms for the AAM… read more here.
