Abstract: It has been established that increased levels of lactylated of tau protein in the brain and CNS is associated with tauopathies and neurodegenerative diseases, and increased levels of lactylated lysine on tau protein has been established as a marked for AD. Compositions and methods for the detection and treatments of tauopathies have been developed. In some forms, the methods identify and quantify lactylated lysine on tau protein in a biological sample from a subject to diagnose a tauopathy, such as AD. In some forms, the methods identify a subject as having or at risk of having a tauopathy. In some forms, the methods include treating the tauopathy. Compositions to identify a tauopathy include lactylated tau binders, such as antibodies are also described.

Abstract: Systems and methods are described for controlling adaptive filtering components. A far end signal may be filtered by each of a foreground filter and a background filter, where both filters are adaptive echo cancellation filters that output echo estimations. Control logic may halt adaptation by the background filter based on a deviation signal. To determine the deviation signal, cross-correlation coefficients for the echo estimations produced by both filters may be determined for each frequency bin of the far end signal. The determined cross-correlation coefficients may be summed across a plurality of the frequency bins. A hysteresis function may then be applied to the sum associated with the filter associated with the echo estimation used to generate a filtered result. The deviation signal may be activated in response to the hysteresis function outputting a high value, which the control logic uses to turn off adaptation by the background filter.

Abstract: A method of double talk detection includes using up-sampling. Audio signals received from the far end are up-sampled prior to output by the loudspeaker at the near end. The microphone at the near end captures audio at the up-sampled rate, and the audio output by the loudspeaker is detectable due to having no energy in the up-sampled frequency bands. The double talk detector uses this information to generate a signal for suppressing the echo of the far end audio from the captured audio signal that is transmitted to the far end.
