This work describes the application of a detailed set of TXRF evaluations to the\nelemental content of assorted tattoo inks, on the market of the city of Concepcion,\nChile. We applied TXRF as a screening method for determining the\ncomposition in 3 sets of tattoo inks, in order to establish, from an inorganic\npoint of view, the composition and purity of the samples, evaluating their elemental\ninnocuousness................................
Bone age assessment (BAA) is an essential topic in the clinical practice of evaluating the biological maturity of children. Because the\nmanual method is time-consuming and prone to observer variability, it is attractive to develop computer-aided and automated\nmethods for BAA. In this paper, we present a fully automatic BAA method. To eliminate noise in a raw X-ray image, we start\nwith using U-Net to precisely segment hand mask image from a raw X-ray image. Even though U-Net can perform the\nsegmentation with high precision, it needs a bigger annotated dataset..................................
The attenuated X-ray transform arises from the image reconstruction in single-photon emission computed tomography. The\ntheory of attenuated X-ray transforms is so far incomplete, and many questions remain open...........................
We report accurate wavelengths for the three most intense lines (resonance\nLine.........................
To investigate the periodic behaviour and relationship of sunspot numbers with cosmic ray intensity and solar wind speed, we\npresent analysis from daily data generated from 1995 January to 2018 December. Cross-correlation and wavelet transform tools\nwere employed to carry out the investigation..............................
