    Abstract: A microfluidic exosome profiling platform integrating exosome isolation and targeted proteomic analysis is disclosed. This platform is capable of quantitative exosomal biomarker profiling directly from plasma samples with markedly enhanced sensitivity and specificity. Identification of distinct subpopulation of patient-derived exosomes is demonstrated by probing surface proteins and multiparameter analyzes of intravesicular biomarkers in the selected subpopulation. The expression of IGF-1R and its phosphorylation level in non-small cell lung cancer (NSCLC) patient plasma is assessed as a non-invasive alternative to the conventional biopsy and immunohistochemistry. Detection of ovarian cancer also is assessed. The microfluidic chip, which may be fabricated of a glass substrate and a layer of poly(dimethylsiloxane), includes a serpentine microchannel to mix a fluid and a microchamber for the collection and detection of exosomes.

  • Patent number: 10308120
    Abstract: An autonomous or semi-autonomous vehicle is provided that is capable of braking itself without a driver depressing the brake pedal. The vehicle has a powertrain that includes an engine, a transmission, and a motor with a connected battery to provide regenerative braking capabilities. Friction brakes are provided to apply when necessary, such as when the battery has a high state of charge and further regenerative braking would overcharge the battery. The braking may be activated in response to a sensor detecting a distance to an object in front of the vehicle. A vehicle controller is programmed to automatically control amounts of regenerative braking and friction braking during a braking event based on a comparison between a regenerative torque limit of the powertrain and a desired brake torque over the brake event to safely brake the vehicle during the brake event.

  • Patent number: 10303818
    Abstract: Processing speeds for generating a model can be enhanced. For example, the model can be generated by using regression coefficient values as weights for independent variables in the model. The regression coefficient values can be determined using a coordinate descent method to find a minimum value of a least absolute shrinkage and selection operator cost function. Each iteration of the coordinate descent method can include determining a starting coordinate based on (i) a previous starting coordinate or a previous regression coefficient value from an immediately prior iteration of the coordinate descent method; (ii) a current regression coefficient value associated with a current iteration of the coordinate descent method; and (iii) a refinement factor configured to minimize a result of a univariate algorithm. Each iteration can also include performing a coordinate descent using the starting coordinate to determine a next regression coefficient value for a next iteration of the coordinate descent method.

  • Patent number: 10275479
    Abstract: Methods, processes and computer-program products are disclosed for use in a parallelized computing system in which representations of large sparse matrices are efficiently encoded and communicated between grid-computing devices. A sparse matrix can be encoded and stored as a collection of character strings wherein each character string is a Base64 encoded string representing the non-zero elements of a single row of the sparse matrix. On a per-row basis, non-zero elements can be identified by column indices and error correction metadata can be included. The resultant row data can be converted to IEEE 754 8-byte representations and then encoded into Base64 characters for storage as strings. These character strings of even very large-dimensional sparse matrices can be efficiently stored in databases or communicated to grid-computing devices.
