Spectra attributed to transitions from the 5sσ a 3Σu+ metastable state of Kr2 to excited Rydberg states have been observed by intracavity and multipass absorption and by laser excitation spectroscopy. Four distinct Rydberg series converging on the

Extensive spectra attributable to transitions from the 4sσ a 3Σ+ metastable state of Ar2 to excited Rydberg states have been observed by intracavity absorption spectroscopy and by laser excitation spectroscopy in the afterglow of a pulsed corona di

A diode-pumped Nd:YLF laser has been acousto-optically mode locked at a 2-GHz repetition rate, giving pulse widths of 7 psec with an average power of 135 mW at a wavelength of 1.047 microm. The 2-GHz pulse rate corresponds to a free-space cavity leng

In this preliminary laboratory study, an acoustical method was evaluated to quantitatively assess the position and patency of an infant-size endotracheal tube (ETT) by in vivo and in vitro measurements. The method consists of emitting an audible soun

In the general population, there are a number of epidemiologic and physiologic factors that have been identified as increasing the risk for SIDS. To date, optimum combinations of these factors do not sufficiently discriminate the high-risk infant in

Five infants had interstitial pneumonitis with constant histologic findings, which was different from that previously described in children. All the infants presented with tachypnea at birth and persistent disease, both clinically and radiographicall

A Nd:YAG laser is end pumped with a 10-W laser-diode bar to produce 1.9 W of TEM(00)-mode power at 1.064 microm. The 10 mm x 1 microm bar is imaged into a 1.8 mm x 390 microm elliptical laser mode. Q-switched operation results in pulse energies of 16

We examined the nature and extent of the autonomic control defect in patients with autonomic dysfunction using power spectral analysis of heart rate fluctuations. Heart rate variability and respiratory patterns were monitored and discrete blood press
