A schematic showing the steps for training a machine learning model to predict an x-ray absorption (XAS) spectrum based on the known structure of a molecule. The molecule's structure is represented as a graph, with atoms as nodes and chemical bonds as edges. This representation captures the ...
X-ray an ionizing radiation that is a powerful MUTAGEN with wavelengths between 10–1 and 10 nm on the ELECTROMAGNETIC SPECTRUM. X-rays are produced by bombarding a metallic target with fast electrons in a vacuum, and are capable of penetrating various thicknesses of solids. Having passed throu...

For each radiation quality and each unfiltered X-ray spectrum the fluence spectrum is shown in a graph together with two other curves. One curve is the fluence spectrum weighted with the energy-dependent kerma factors; the second is the fluence spectrum weighted with the energy-dependent ...
PROBLEM TO BE SOLVED: To enhance the visibility of the X-ray spectrum displayed on a wavelength dispersion type X-ray analyzer using a plurality of spectral crystals and to facilitate the comparative evaluation with the X-ray spectrum obtained by an energy dispersion type X-ray analyzer. ...
