TRIGONOMETRIC REGRESSIVE SPECTRAL ANALYSIS RELIABLY MAPS DYNAMIC CHANGES IN BAROREFLEX SENSITIVITY AND AUTONOMIC TONE: THE EFFECT OF GENDER AND AGE.

Trigonometric regressive spectral analysis reliably maps dynamic changes in baroreflex sensitivity and autonomic tone: the effect of gender and age.

BACKGROUND: The assessment of baroreflex sensitivity (BRS) has emerged as prognostic tool in cardiology.Although available computer-assisted methods, measuring spontaneous fluctuations of heart rate and blood pressure in the time and frequency domain are easily applicable, they do not allow for quantification of BRS during cardiovascular adaption p

Effect of inner channel geometry on solidification performance of phase change material (PCM) in double-pipe thermal energy storage

Advantages such as high energy storage density and low heat losses have made phase change materials (PCMs) preferable in energy storage.However, the very low thermal conductivity of PCMs is the most important obstacle to improving melting and solidification performance of PCMs.To improve the thermal conductivity of PCM, the combination INTENSIVE HY
