Chest, 1989
The pulse oximeter, a widely used noninvasive monitor of arterial oxygen saturation, has numerous applications in anesthesiology and critical care. Although pulse oximetry is considered sufficiently accurate for many clinical purposes, there are significant limitations on the accuracy and availability of pulse oximetry data.

Pediatric Emergency Care, 1987
The pulse oximeter provides a noninvasive, continuous, and generally valid measure of SaO2. Armed with a basic understanding of its operating principles and limitations, and the proper interpretation of SaO2, the emergency physician will find the pulse oximeter to be a useful instrument for the detection of hypoxia in infants and children.

Practical Pulse-Shaping Waveforms for Reduced-Cyclic-Prefix OTFS
IEEE Transactions on Vehicular Technology, 2019In this paper, we model $M\times N$ orthogonal time frequency space modulation (OTFS) over a $P$-path doubly dispersive channel with delays less than $\tau _{\max }$ and Doppler shifts in the range $(\nu _{\min },\nu _{\max })$.

Corrigan’s Pulse and Quincke’s Pulse
New England Journal of Medicine, 2018Corrigan’s Pulse and Quincke’s Pulse A 58-year-old man with a bioprosthetic aortic valve presented with exertional dyspnea. Videos show rapidly declining pulsation of the right carotid artery and capillary pulsation of the index finger, thumb, and nail bed, findings suggestive of severe aortic regurgitation.

Divided-pulse amplification of ultrashort pulses
Optics Letters, 2006We propose and demonstrate a new approach, to the best of our knowledge, for avoiding nonlinear effects in the amplification of ultrashort optical pulses. The initial pulse is divided longitudinally into a sequence of lower-energy pulses that are otherwise identical to the original, except for the polarization.
