Background: The basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. Esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. In addition, the stethoscope is not applicable for continues monitoring, and it is u...

Abstract The acoustic echo cannot be entirely removed by linear adaptive filters due to the nonlinear relationship between and far-end signal. Usually, a post-processing module is required further suppress echo. In this paper, we propose residual suppression method based on modification of dual-path recurrent neural network (DPRNN) improve quality speech communication. Both signal auxiliary sig...

In the classic Precise Point Positioning (PPP) approach, observations of Global Navigation Satellite Systems (GNSS) are processed at network level to generate satellite clocks and positions. This information can be used enable accurate point positioning for a single GNSS receiver. PPP Real-Time Kinematic (PPP-RTK) phase biases considered as well, enabling ambiguity resolution user levels. this ...

Observations of Interplanetary Scintillation (IPS) are an efficient remote-sensing method to study the solar wind and inner heliosphere. From 2016 2018, some distinctive observations IPS sources like 3C 286 279 were accomplished with Five-hundred-meter Aperture Spherical radio Telescope (FAST), largest single-dish telescope in world. Due 270-1620 MHz wide frequency coverage Ultra-Wideband (UWB)...
