recommendations! Published in 2024 at "Research in Astronomy and Astrophysics"

DOI: 10.1088/1674-4527/ada422

Abstract: Clock difference between the ensemble pulsar timescale (PT) and the International Atomic Time (TAI) PT-TAI derived from the International Pulsar Timing Array (IPTA) data set indicates a very similar variation trend with the Terrestrial Time… read more here.

DOI: 10.1186/s13640-018-0312-8

Abstract: This paper proposed a snowfall model as a novel smoothing filter. The pixel composition of the image was similar to the geographic features, so it could be smooth because of snow accumulation. In the snowfall… read more here.

DOI: 10.3390/app9224968

Abstract: Electrocardiographic (ECG) signal is essential to diagnose and analyse cardiac disease. However, ECG signals are susceptible to be contaminated with various noises, which affect the application value of ECG signals. In this paper, we propose… read more here.
