DOI: 10.1080/07474938.2016.1140277

Abstract: ABSTRACT We present a time-domain goodness-of-fit (gof) diagnostic test that is based on signal-extraction variances for nonstationary time series. This diagnostic test extends the time-domain gof statistic of Maravall (2003) by taking into account the… read more here.

DOI: 10.1088/1741-2552/aa7d94

Abstract: OBJECTIVE Multi-channel cuff electrodes have recently been investigated for extracting fascicular-level motor commands from mixed neural recordings. Such signals could provide volitional, intuitive control over a robotic prosthesis for amputee patients. Recent work has demonstrated… read more here.

recommendations! Published in 2022 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stad1047

Abstract: In a sky-averaged 21-cm signal experiment, the uncertainty on the extracted signal depends mainly on the covariance between the foreground and 21-cm signal models. In this paper, we construct these models using the modes of… read more here.

DOI: 10.1109/lgrs.2016.2633622

Abstract: In this letter, we propose an isophase-based method for human life signal extraction using a stepped-frequency continuous-wave through-the-wall radar. Isophase is the line connected by points of the same phase value in the slow time… read more here.
