Low-Rank Tensor Completion for Image and Video Recovery via Capped Nuclear Norm

open access: yesIEEE Access, 2019
Inspired by the robustness and efficiency of the capped nuclear norm, in this paper, we apply it to 3D tensor applications and propose a novel low-rank tensor completion method via tensor singular value decomposition (t-SVD) for image and video recovery.

A Comprehensive Timing Analysis of Individual Pulses in X-Ray Bursts from SGR J0501+4516

open access: yesThe Astrophysical Journal Supplement Series
The pulses in X-ray-burst (XRB) light curves from soft gamma-ray repeaters (SGRs) are generally thought to arise from magnetic crustal fractures or magnetic reconnection, reflecting the evolution of the energy release process in magnetars. In this study,

Revisiting the Fundamental Planes of Black Hole Activity for Strong Jet Sources

open access: yesThe Astrophysical Journal
Whether the X-ray emissions of strong jet sources originate from disk+coronas or jets is still controversial. In this work, we constructed a strong jet sample containing 50 flat-spectrum radio quasars, 51 low-synchrotron-peaked BL Lac objects, and 18 ...
