Abstract: According to at least one embodiment, a method of determining a predictive index indicating a level to which a human subject is at risk of developing hypoactive delirium includes: extracting first features of first audio content and first video content continuously capturing the human subject in a setting over a first period; establishing a behavioral baseline specific to the human subject based on the extracted first features; providing the established behavioral baseline to a neural network; extracting second features of second audio content and second video content continuously capturing the human subject in the setting over a second period subsequent to the first period; providing the extracted second features to the neural network for determining the predictive index based on the established behavioral baseline and the extracted second features; and outputting an alert based on the determined predictive index being above a threshold value.

Abstract: Systems and methods for purifying or recycling polymeric materials such as polycarbonates are disclosed. Such methods may include performing two or more extractions using differing solvent media to remove non-target materials and attain a purified composition of a target polymer. Other steps including dissolution, precipitation, filtration, and/or centrifugation may also be performed in the methods of the present invention.

Abstract: Polycarbonates are recovered from polymer blends by liquid chromatography. Polycarbonate recovered by the process can be reused in new applications. The invention can be extended to recycling of other polymers present in the blends.

Abstract: The present invention relates to methods for producing Saccharomyces strains that are capable of growth on xylose as a sole carbon source at a desired growth rate, (such as at least one generation per 48 hours), strains made by such methods, and Saccharomyces strains that grow at a growth rate of at least one generation per 48 hours using xylose as a sole carbon source for growth made by non-recombinant methods.
