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.

Localization Aftereffects with Pulse-Tone and Pulse-Pulse Stimuli
The Journal of the Acoustical Society of America, 1965When a pulse is presented from one position in space near in time to the beginning of a tone burst coming from another position in space, the tone burst may be perceived to be displaced toward the pulse. Measurements of displacement effects are given for various angles of separation of sources and duration of tone. A related type of displacement effect

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.

To Pulse or Not to Pulse, Is That the Question?
Circulation, 2015Efferent sympathetic nerve discharge is both gated to the cardiac cycle and inhibited by afferent input from cardiac, aortic, and carotid mechanoreceptors stimulated by rhythmic atrial and conduit artery distension. In patients with chronic heart failure as a consequence of impaired systolic function, both this gating and the blood pressure–muscle ...

Pulse on Pulse Deinterleaving Radar Algorithm
2020 10th Annual Computing and Communication Workshop and Conference (CCWC), 2020This paper intends to demonstrate interleaving radar pulses extracted from a deinterleaving algorithm and to discuss the problems encountered from deinterleaving radar pulses. The deinterleaving algorithm will be handling multiple pulse trains at a time.

The Annals of Thoracic Surgery, 1978
Pulsatile and nonpulsatile blood flow have been intensely studied for cardiopulmonary bypass (CPB), isolated organ perfusion, and myocardial preservation. Although early studies differed, later ones have shown the benefits of pulsatile flow. Kidney function, lymph flow, and oxygen consumption are increased during pulsatile perfusion. Also, nonpulsatile

Pulse-by-pulse reoptimization of the synthesis filter in pulse-based coders
IEEE Transactions on Speech and Audio Processing, 1998Two iterative algorithms for pulse-based linear predictive (PB-LP) analysis are developed. At the kth step, one of the algorithms assumes that the pulse locations of k pulses are known and calculates the LP coefficients jointly with k pulse amplitudes. In contrast, the other algorithm assumes that the previous k-1 pulse amplitudes are known and jointly

Pulse distortion of a scattered chirped pulse
Applied Optics, 1997We have studied the time-dependent properties of a chirped short pulse when the pulse is scattered by a spherical particle. We used generalized Lorentz-Mie formulas to study the scattered electrical field and pulse distortion. Plane wave Gaussian pulses of different chirps with a constant pulse-filling coefficient l(0) = 1.98 have been studied.

Cyclophosphamide: To pulse or not to pulse?
The American Journal of Medicine, 1990(lthough daily low-dose (2 mg/kg) oral cyclophosphamide (CP) is effective in the treatment of corticosteroid-resistant vasculitic diseases [l-3], this regimen has a low therapeutic/toxic profile. Major toxicities associated with daily CP administration include neoplasm (acute myelogenous leukemia and bladder cancer), hemorrhagic cystitis, bladder ...

Proceedings of the 10th international conference on Human computer interaction with mobile devices and services, 2008
This paper introduces a device that creates remote intimacy by the use of two rings named "united-pulse". Each ring can measure the wearer's heartbeat and send it to the partner's ring. Hereby, artificial corporeality is created between the couple. By means of a working prototype, united-pulse has been successfully tested. Among the 28 participants the
