This corresponds to 1.16 Lambda / D at 109.4 GHz, which agrees well with the low - frequency value measured at 9.0 GHz.

Not exact matches

The KIT researchers were involved in the development of an instrument that stores all values measured and indicates frequency changes.

«This shows that measuring high frequency variability during this early critical window of postnatal development has value for identifying NEC risk at a time when symptoms are not evident and interventions to improve the parasympathetic nervous system activity can be given,» said researcher R. Alberto Travagli, professor of neural and behavioral sciences.

However, peak time is often not a good statistical measure because it is a discrete value that depends on frequency of blood sampling and, in the case of relatively flat concentrations near the peak, on assay reproducibility.

The measured values for what the capacitance of what «the capacitor» should be do not work out to the hypothetical frequency.

Our analysis of 700,000 hip and 150,000 elbow records in the publically available OFA database demonstrate clearly that efforts to reduce the frequency and severity of hip dysplasia, and its secondary osteoarthritis in the USA based on radiographic evaluation (phenotype), have met with meager improvement in genetic quality as measured by estimated hip score breeding values since 1970 (Hou et al., 2014).

The subskin SST, SSTsubskin, is representative of the SST at the bottom of the skin temperature layer and is usually the value measured by a low - frequency (6 - 10 GHz) microwave radiometer.

«Abstract - Over 5000 absolute absorption values for pressure - broadened O2 lines in dry air were measured at frequencies from 49 to 67 GHz in O.l - GHz - increments.

Furthermore, a study investigating parasympathetic and sympathetic activity through the use of RSA in 12 patients with BPD and 28 healthy controls had ECG recorded for three 5 min stages (at rest or stressed) found BPD was associated with lower values of RSA suggesting increased levels of sympathetic activity and decreased levels of parasympathetic activity.33 Meyer et al recorded 5 min ECG signals on 27 participants with BPD, 23 in remission from BPD, 18 suffering from PTSD and 23 healthy controls.34 Significant differences were only found between PTSD participants and controls; however, BPD participants had reduced variability across linear time and frequency domain measures compared with controls.

RMSSD is sensitive to high - frequency heart period fluctuations in the respiratory frequency range and is used as an index of vagal cardiac control.3) In the frequency - domain analysis, the power spectra of three frequency bands are calculated: very low frequency (VLF; 0.005 - 0.040 Hz), low frequency (LF; 0.04 - 0.15 Hz), high frequency (HF; 0.15 - 0.40 Hz), and total power (TP), including VLF, LF, and HF.1) For the non-linear complexity measure, the approximate entropy (ApEn) is calculated.4) The ApEn is a parameter that was developed to quantify the degree of regularity versus unpredictability in a higher dimensional attractor reconstructed from a time series, such as the instantaneous heart rate time series.5, 6) A lower ApEn value reflects a higher degree of regularity, and the higher the entropy value, the more unpredictable the time series.5, 6)
