Abstract: An all-solution electrode fabrication process is provided. The process comprises the steps of: i) preparing and activating a shrinkable polymer substrate for deposition of a a) conductive film; ii) modifying the substrate to incorporate a linker; iii) immobilizing particles of a conductive material on the linkers of the substrate to form a conductive film on the substrate; and vi) heating the modified substrate to a temperature sufficient to cause contraction of the polymer substrate and to result in micro- and/or nano-texturing in the conductive film. The process advantageously yields a novel multi-scale electrode device comprising a polymer substrate; and a textured electro-conductive film linked to the substrate.

Abstract: The present disclosure relates to an assay that measures the level of factor Xa inhibitors in a sample by detecting residual factor Xa activity. In particular, the assay utilizes a mutant variant of prothrombin that lacks proteolytic activity; a prothrombinase complex mixture; and a thrombin-specific inhibitor and measures the factor Xa activity.
Abstract: Systems and methods relating to fault detection and diagnosis. Signals received from sensors are first filtered to remove noise and are then analyzed using wavelet packet transform (WPT) based PCA. The results of the PCA analysis are then automatically classified to thereby quickly and easily determine what issues there may be in a finished product or in a machine being monitored.
