Rapid corticosterone pulses

Journal of Steroid Biochemistry, 1983
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, 1986
Abstract 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

1989
In 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).
