Methods, computer-readable media, and systems are provided for determining whether a data point indicates a presence of a sub-visible cloud using visible near-infrared data and short wavelength infrared data. The method includes saving a prefetch code start address by the parent core. The transaction data includes a product and a store. The C9+-containing stream with a transalkylation catalyst under conditions effective to convert C9+-aromatics to C8\u2212-aromatics and produce a transalkylated stream, which is recycled together with the isomerized stream to the para-xylene recovery section. In the sheet scanner, photoelectric conversion devices formed by organic semiconductor devices are arranged.
