    Abstract: Wireless signal classifiers and systems that incorporate the same may include an energy-based detector configured to analyze an entire set of measurements and generate a first signal classification result, a cyclostationary-based detector configured to analyze less than the entire set of measurements and generate a second signal classification result; and a classification merger configured to merge the first signal classification result and the second signal classification result. Ensemble wireless signal classification and systems and devices the incorporate the same are disclosed. Some ensemble wireless signal classification may include energy-based classification processes and machine learning-based classification processes. In some embodiments, incremental machine learning techniques may be incorporated to add new machine learning-based classifiers to a system or update existing machine learning-based classifiers.

    Abstract: Embodiments of the disclosure are drawn to a low-voltage temperature sensor. The temperature sensor may include a waveform generator, a complementary-to-absolute-temperature (CTAT) voltage generator, a voltage reference, two comparators, and digital logic. A waveform of the waveform generator may be compared to both the CTAT voltage and the voltage reference. The output of the comparison of the CTAT and the waveform may be a pulse-width modulated signal that is temperature-dependent. The output of the comparison of the voltage reference and the waveform may be a signal with constant pulse width. The digital logic may receive the pulsed signals and take a ratio of the two signals to determine a temperature.

    Abstract: The disclosure provides a method of reducing formation of fibrotic tissue in a uterus of a subject in need thereof, comprising applying a mesenchymal stem cell (MSC) sheet to the uterus of the subject, wherein the MSC sheet comprises one or more layers of aggregated confluent mesenchymal stem cells (MSCs), and wherein applying the MSC sheet to the uterus reduces the formation of fibrotic tissue in the uterus relative to a uterus in which the MSC sheet is not applied. The disclosure also provides a method of increasing myometrial regeneration in a uterus of a subject in need thereof, comprising applying a mesenchymal stem cell (MSC) sheet to the uterus of the subject, wherein the MSC sheet comprises one or more layers of aggregated confluent mesenchymal stem cells (MSCs), and wherein applying the MSC sheet to the uterus increases myometrial regeneration relative to a uterus in which the MSC sheet is not applied.

    Abstract: An interferometry system includes a plurality of coherent light sources that each generate a beam of coherent light. Separate waveguide pathways are optically associated with each coherent light source. Each separate waveguide pathway has an endpoint configured to emit at least a portion of the beam of coherent light from the associated light source. A plurality of photodetectors is optically associated with waveguide pathways. In some cases, a retroreflector receives the light emitted from the endpoints, modulates the received light, and directs the modulated light back to the endpoints. The modulated light and a portion of the coherent light reflected from the endpoint of the waveguide pathway receiving the modulated light is directed a photodetector.
