This paper considers the problem of estimating the motion parameters of a low-observable high-speed maneuvering target with high-order motions, where the target’s complex motions will result in the range migration (RM) and Doppler frequency migration (DFM) effects within the observation time interval, which will significantly affect the rada

Mechanical defects and partial discharge (PD) defects can appear in the indoor switchgear of substations or distribution stations, making the switchgear a safety hazard.However, traditional acoustic methods detect and identify these two types of defects separately, ignoring the general recognition of audio signals.In addition, the process of using
Atypical type A thymomas exhibit more aggressive features than conventional type A thymomas.Type AB thymomas rarely have atypical type A components.We report a rare case of type AB thymoma with an atypical type A component, that was identified after pulmonary metastasectomy 11 years after the primary surgery and long-term follow-up after recurrence
