A method for measuring spatial resolution based on clinical chest CT sequence images
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study aimed to develop and validate a method for characterizing the spatial resolution of clinical chest computed tomography (CT) sequence images. Methods An algorithm for characterizing spatial resolution based on clinical chest CT sequence images was developed in Matlab (2021b).

Deconstructing Photospheric Spectral Lines in Solar and Stellar Flares
The Astrophysical JournalDuring solar flares, spectral lines formed in the photosphere have been shown to exhibit changes to their profiles despite the challenges of energy transfer to these depths.

When atomic norm meets the G-filter: A general framework for line spectral estimation [PDF]
arXivThis paper proposes a novel approach for line spectral estimation which combines Georgiou's filter bank (G-filter) with atomic norm minimization (ANM). A key ingredient is a Carath\'{e}odory--Fej\'{e}r-type decomposition for the covariance matrix of the filter output.
