Objective: This study aims to systematically evaluate the safety and efficacy of curcumin as an adjunctive treatment for patients with ulcerative colitis (UC) and to assess the methodological quality of the published studies.
Methods: A comprehensive search was conducted in PubMed, Embase, and CENTRAL databases for randomized controlled trials published up to August 18, 2023. Two independent reviewers screened studies based on predefined criteria.
The inherent shortcoming of POCS (Projection Onto Convex Sets) is its sensitiveness to noise. The restoration quality of POCS based super resolution will severely decline when the noise is larger. In practical applications, the low resolution images generally include some kinds of noise, such as camera internal noise, transmission system noise and coherent noise.

A hyperspectral interference image compression algorithm based on fast hierarchical alternating least squares nonnegative tensor Tucker decomposition (FHALS-NTD) is proposed. Firstly, the interference hyperspectral image is decomposed by 3-D OPD lifting-based discrete wavelet transform (3D OPT-LDWT) in the OPD direction. Then, the 3D DWT sub-bands decomposed are used as a three order nonnegative tensor, which is decomposed by the proposed FHALS-NTD algorithm to obtain 8 core tensors and 24 unknown component matrices.
