DOI: 10.1088/1674-1056/acd36b
Abstract: The compounds composed of transition meatal cations and pnictide anions provide a rich platform for novel physical phenomena. Here we report the observation of a phase transition at ~ 70 K and 145 K from… read more here.

DOI: 10.1103/physrevmaterials.5.014410
Abstract: The rhombohedral distortion-driven occurrence of the spontaneous electric polarization at a reasonably high temperature $(T)$ and an exchange bias (EB) effect below the antiferromagnetic (AFM) N\'eel temperature $({T}_{N})$ are revealed in ${\mathrm{ZnFe}}_{2}{\mathrm{O}}_{4}$. We observe the… read more here.

DOI: 10.1109/jsen.2024.3506831
Abstract: Forward-looking sonar (FLS) image segmentation aims to accurately locate underwater objects, providing essential support for marine engineering. Unlike natural optical images, FLS images have weak semantic content and complex background, posing segmentation challenging for existing… read more here.

DOI: 10.1109/tip.2020.2983849
Abstract: In this work, we propose an overcomplete representation of multiview imagery for the purpose of compression. We present a rate-distortion (R-D) driven approach to decompose multiview datasets into two additive parts which can be interpreted… read more here.
