The degree of squeezing generated by parametric downconversion or four-wave mixing can be limited by the ratio of the nonlinear coupling to the linear losses in many practical systems. This ratio can be enhanced by increasing the pump power used for the nonlinear coupling in many solid nonlinear systems where the linear losses are not directly related ...

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

In addition to lasers, intense pulsed light (IPL) sources are widely used in medicine to treat various indications, such as vascular lesions, irregular pigmentation and hypertrichosis. In contrast to lasers, IPL systems are broadband flash lamps that emit polychromatic incoherent light ranging from visible to infrared (500-1,300 nm).

If micro-sampling techniques are used in conjunction with a highly sensitive radioimmunoassay procedure, it is possible to obtain repeated rapid measurements of plasma corticosterone concentrations from unanesthetized rats. Such a procedure reveals the existence of rapid corticosterone pulses with a duration of less than 60 s and amplitudes as great as

Pulse distortions in tilted pulse schemes for ultrashort pulses
Optics Communications, 1986Abstract Analytical expressions are found for the propagation of the amplitude of tilted ultrashort pulses. The distortions arising are the pulse broadening, tilt angle decrease, chirp, frequency shift and spatial profile variation. Expressions for these quantities are found and it is shown that the mechanisms responsible for the distortions are the ...

Pulse Cycles, Pulse Sequences, and Tissue Contrast
1989In order to create an image in space, steps 2 and 3 of MRR must be repeated multiple times. That is, the RF pulse must be applied over and over with relaxation and signal measurement occurring after each application of the pulse. The number of such repetitions is usually on the order of 128 or 256 (or some other multiple of 64).
