Abstract: Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid.

Abstract: Circuits, methods, and apparatus for training a phase shift circuit to provide a phase shift for improved data recovery. A specific embodiment of the present invention provides a variable delay cell. A delay through the variable delay cell is changed while training patterns are received. The presence of errors in the received data pattern is tracked, and from the presence or absence of errors a preferred delay is selected and used for receiving data.
