abstract background: infants’ feeding is one of the critical periods in women’s health that can influence their life. the purpose of this study was to investigate the relationship between infants’ feeding patterns and mothers’ physical and psychological dimensions of quality of life. materials and methods: in this cross-sectional study, 189 mothers were selected by convenience sampling (n = 63 ...

The aim of this work was to evaluate the reliability of the square of the signal-to-noise ratio rate, [Formula: see text], as a precise measurement for quality control test in a digital fluoroscopy system. The quasi-ideal model observer was used to measure [Formula: see text] The dose rate, pulse rate and field of view were varied, and their effect on dose efficiency, defined as [Formula: see t...

The algorithms based on the technique of optimal $k$-thresholding (OT) were recently proposed for signal recovery, and they are very different from traditional family hard thresholding methods. However, computational cost OT-based remains high at current stage their development. This stimulates development so-called natural ...
