We present the first intermediate-resolution (λ/Δλ = 3000) spectrum of the bright quasi-stellar object 3C 273 at wavelengths between 900 and 1200 A. Observations were performed with the Berkeley spectrograph aboard the ORFEUS II mission. We detect

Computers in Cardiology 1995.
Variability of arterial blood pressure (BPV) and heart rate (HRV) were investigated in 26 patients shortly after CABG surgery under two conditions: During the first recording patients had sinus rhythm of 65 to 88 beats per minute; after that the atri

Heart rate (HRV) and blood pressure (BPV) variability were investigated in 25 patients undergoing CABG surgery. At four stages, 5-minutes of on-line data were used to calculate spectral power in high (0.15 to 0.4 Hz), low (0.04 to 0.15 Hz), and very
