Abstract: Systems and methods for identifying a printer that generated a printed document. The methods comprise: generating an electronic image of the printed document; obtaining a dot pattern contained on the printed document via an analysis of the electronic image; overlaying the dot pattern on Voronoi diagrams; selecting a first Voronoi diagram from the Voronoi diagrams that has a single dot of the dot pattern in each of at least some cells thereof; and identifying a printer associated with the first Voronoi diagram that was selected from the Voronoi diagrams. The printer associated with the first Voronoi diagram comprises the printer that generated a printed document.

Abstract: Embodiments of the instant invention relate to applying motor learning to promote remyelination following demyelination in a subject having a condition or disease. In certain embodiments, applying motor learning alone or in combination with vagus nerve stimulation (VNS) induces the production of new and preserves surviving oligodendrocytes. In accordance with certain embodiments of the disclosure, motor learning, when properly timed, enhances oligodendrogenesis after injury and recruits mature oligodendrocytes to participate in remyelination through the generation of new myelin sheaths. In other aspects of the disclosure, VNS paired with motor learning enhances remyelination following demyelination.
