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

Journal of Magnetic Resonance, 2010
We introduce the concept of cooperative (COOP) pulses which are designed to compensate each other's imperfections. In multi-scan experiments, COOP pulses can cancel undesired signal contributions, complementing and generalizing phase cycles. COOP pulses can be efficiently optimized using an extended version of the optimal-control-based gradient ascent ...

Critical Care Nursing Clinics of North America, 1999
Pulse oximetry is one of the most commonly applied technologies in acute and critical care. It has the potential to continuously monitor pulmonary function, avoid unnecessary blood gases, and alert clinicians to hypoxemic events that are not readily apparent by physical assessment. Due to these advantages, pulse oximetry has a firm place in health care.

Current Opinion in Internal Medicine, 2006
Pulse oximetry is now a ubiquitous and essential tool of modern medicine, and while it is a relatively recent invention, the technology has rapidly matured since the first commercially available oximeters were introduced in the 1970s. This review seeks to provide an overview of the basic physical operation of the probe and discuss its limitations ...

NMR in Biomedicine, 1997
Adiabatic pulses are sometimes considered to be mysterious and exotic entities which are difficult to understand, complex to generate and impractical to implement. This work is an attempt to bring familiarity and to fulfill the preliminary needs of anyone interested in learning more about this subject.

Mode-locked dark pulse Kerr combs in normal-dispersion microresonators
Nature Photonics, 2014The generation of Kerr frequency combs in a coherently driven nonlinear microresonator is now extensively investigated more generally by the research community as a potentially portable technology for a variety of applications.

The pulse oximeter is a device for non-invasive, continuous measurement of oxygen saturation. As such it is arguably one of the most important intraoperative monitors at the disposal of anaesthetists, and efforts are being made to make pulse oximeters available at all operating locations throughout the world [Walker et al. 2009].

Pulse oximetry is a widely used, non-invasive technique for assessing arterial oxygenation by measuring oxygen saturation in peripheral blood vessels. It is a simple technique, but needs to be carried out with care to obtain reliable results. This article provides guidance on the safe use of pulse oximetry and identifies some of the advantages and ...

2010 IEEE 26-th Convention of Electrical and Electronics Engineers in Israel, 2010
The Airy beam (AiB) has attracted a lot of attention recently because of its intriguing features; the most distinctive ones are the propagation along curved trajectories in free space and the weak diffraction. We have previously shown that the AiB is, in fact, a caustic of the rays that radiate from the tail of the Airy function aperture distribution ...

Elementary Classical electrodynamics theory of pulse is discussed. The simplest possible models of Fourier-transform limited laser pulses are introduced with Gaussian and Hann envelope. Its frequency content and the power spectrum is also discussed.
