  • Publication number: 20230187078
    Abstract: The present disclosure presents systems and methods of predicting overdose risk using prescription data. One such method comprises analyzing, by a computing device, a plurality of document datasets, where the document datasets comprising prescription data for a controlled substance, hospital discharge data, socioeconomic data, and vital statistics data of a subject; predicting an overdose risk for the subject within a set period of time based on the plurality of document datasets; aggregating overdose risk predictions involving the controlled substance for a plurality of subjects within a geographic region; and/or calculating an overall overdose risk involving the controlled substance for the geographic region.

  • Publication number: 20210023514
    Abstract: Disclosed herein are continuous flow systems having bifurcated fluidic flow mixers. The mixers operate, at least partially, by Dean vortexing. Accordingly, the mixers are referred to as Dean Vortex Bifurcating Mixers (“DVBM”). DVBMs utilize Dean vortexing and bifurcation of the fluidic channels that form the mixers to achieve the goal of optimized microfluidic mixing.
