Abstract: A system may generate synthetic data via an iterative procedure that improves diversity and accuracy of the synthetic data by evaluating performance metrics of respective portions of the generated synthetic data prior to generating subsequent portions of the synthetic data. The system may receive an input indicating seed data and a task description and, based on the seed data and the task description, retrieve data from a data source. The system may generate first examples from the retrieved data, evaluate performance of the seed data based on the generated first examples, and weight the seed data accordingly. Using the weighted seed data and the first examples, the system may retrieve new data from the data source and perform another iteration of example generation and evaluation. The system may continue to perform iterations of example generation and evaluation to generate an amount of data requested as indicated by the input.

Abstract: The disclosed technology relates to methods, voice enhancement systems, and non-transitory computer readable media for real-time voice enhancement. In some examples, input audio data including foreground speech content, non-content elements, and speech characteristics is fragmented into input speech frames. The input speech frames are converted to low-dimensional representations of the input speech frames. One or more of the fragmentation or the conversion is based on an application of a first trained neural network to the input audio data. The low-dimensional representations of the input speech frames omit one or more of the non-content elements. A second trained neural network is applied to the low-dimensional representations of the input speech frames to generate target speech frames. The target speech frames are combined to generate output audio data. The output audio data further includes one or more portions of the foreground speech content and one or more of the speech characteristics.

Abstract: Applicants sought to express human iduronate-2-sulfatase (hIDS) in the brain endothelium of a mouse model of Mucopolysaccharidosis type II (MPSII, Hunter's syndrome) to enable enzyme secretion into the brain parenchyma. In this disorder, IDS deficiency results in the pathophysiological accumulation of heparan and dermatan sulfate GAGs. To test the hypothesis, Applicants chose AAV-BI30, an AAV9-derived capsid that has an enhanced in vivo tropism specific to the endothelium in the rodent CNS and can transduce human brain vascular endothelial cells in vitro more efficiently than AAV9. Applicants show that systemic delivery of AAV-BI30: hIDS restored IDS enzyme activity in the brain, liver, and serum of IDS-KO mice (FIG. 1). Importantly, AAV-BI30-mediated gene transfer resulted in the correction of GAG accumulation in the brain (FIG. 2). This effect was not observed when using the AAV-BI30 vector packaging a non-secreting version of hIDS.

Abstract: Methods for preparing ceria-zirconia (CZO) materials calcined with precious group metals (PGM) include calcining a CZO material with PGM. The calcined CZO/PGM catalyst is reduced at a temperature of ?1000° C. to ?1100° C. for a time of ?0.5 hour to 1 hour to form a (CZO/PGM)-pyrochlore catalyst. The (CZO/PGM)-pyrochlore catalyst exhibits superior oxygen storage capacity characteristics as a three-way catalyst in vehicle exhaust gas systems.

Abstract: An example system includes two objects each having a known dimension and positioned spaced apart by a known distance, and a fixture having an opening for receiving an imaging device and for holding the two objects in a field of view of the imaging device such that the field of view of the imaging device originates from a point normal to a surface of the base. The fixture holds the imaging device at a fixed distance from an object being imaged and controls an amount of incident light on the imaging device. An example method of determining image scaling includes holding an imaging device at a fixed distance from an object being imaged, and positioning the two objects in the field of view of the imaging device such that the field of view of the imaging device originates from a point normal to a line formed by the known distance.
