Abstract: Speech detection can be achieved by identifying a speech segment within an audio segment using image classification. An audio segment of radio communications is obtained. An audio sub-segment within the audio segment is extracted. A sampled histogram is generated of a plurality of sampled values across a sampled time window of the audio sub-segment. A two-dimensional image is generated that represents a two-dimensional mapping of the sampled histogram along a first dimension and a predefined histogram along a second dimension that is orthogonal to the first dimension. The two-dimensional image is provided to an image classifier previously trained using the predefined histogram. An output is received from the image classifier based on the two-dimensional image. The output indicates whether the audio sub-segment contains speech.

Abstract: A system for processing biological or other samples includes an array of transducer elements that are positioned to align with sample wells in a microplate. Each transducer element produces ultrasound energy that is focused towards a well of the microplate with sufficient acoustic pressure to cause inertial cavitation. In one embodiment, the transducers are configured to direct ultrasound energy into cylindrical wells. In other embodiments, the transducer elements are configured to direct ultrasound energy into non-cylindrical wells of a microplate.

Abstract: A protected fluid circuit can utilize osmotic membranes or other membrane types that are highly selective to urea transport. The membranes can achieve sufficient diffusional flux of urea in a forward osmosis geometry. When combined with a oxidation unit, this protected geometry can have a high selective flux of urea from the spent dialysate side to the urea removal side; balance of fluid (water) levels in patients by forward osmotic flow by controlling water evaporation rate through an vapor permeable membrane; protection of patient dialysate/blood loop from oxidation by-products; and an ability to optimize oxidation system performance (pH, ionic strength, other electrolytes, etc.) that would be otherwise incompatible with blood contact.

Abstract: A portable hemopurification system can remove one or more uremic toxins from blood of a patient. The hemopurification system includes a dialyzer with a dialyzing membrane. Blood from a patient is provided to the dialyzer on one side of the dialyzing membrane, and a negative-pressure pump applies negative pressure on the opposite side of the dialyzing membrane to provide ultrafiltration of uremic toxins from the blood. The system includes a replacement fluid line to deliver replacement fluid to the blood. The system includes load cells to measure the replacement fluid flow, effluent flow, and returned blood flow. The systems uses the fluid weights for the control of pumps to provide stable flow through the system.

Abstract: In some embodiments, a computer-implemented method of automatically predicting progression of age-related macular degeneration is provided. An image analysis computing system receives optical coherence tomography data (OCT data). The image analysis computing system determines an optical attenuation coefficient for each pixel of the OCT data to create optical attenuation coefficient data (OAC data) corresponding to the OCT data. The image analysis computing system determines an area exhibiting geographic atrophy based on at least one of the OCT data and the OAC data. The image analysis computing system measures one or more attributes within an adjacent area that is adjacent to the area exhibiting geographic atrophy, and the image analysis computing system determines a predicted enlargement rate based on the one or more attributes within the adjacent area.

Abstract: Provided herein are methods and systems pertaining to sequencing units of analytes using nanopores. In general, arresting constructs are used to modify an analyte such that the modified analyte pauses in the opening of a nanopore. During such a pause, an ion current level is obtained that corresponds to a unit of the analyte. After altering the modified analyte such that the modified analyte advances through the opening, another arresting construct again pauses the analyte, allowing for a second ion current level to be obtained that represents a second unit of the analyte. This process may be repeated until each unit of the analyte is sequenced. Systems for performing such methods are also disclosed.
