Circadian Phase and Phase Angle Disorders in Primary Insomnia [PDF]

Sleep, 2017
We aimed to identify the prevalence of circadian phase and phase angle abnormalities in patients with insomnia.We conducted a cross-sectional, multicenter study at three sleep laboratories in the United States and Australia. Patients with insomnia and healthy control participants completed a sleep log for 7 days.

Determinants of bioelectrical phase angle in disease [PDF]

British Journal of Nutrition, 2011
Phase angle (PhA), a parameter of bioelectrical impedance analysis, is a well-known predictor of morbidity and mortality in various diseases. The causes of decreased PhA are, however, not yet completely understood. We therefore investigated determinants of PhA in 777 hospitalised patients in a retrospective analysis.

Phase angle by electrical bioimpedance is a predictive factor of hospitalisation, falls and mortality in patients with cirrhosis

Scientific Reports, 2021
The phase angle is a versatile measurement to assess body composition, frailty and prognosis in patients with chronic diseases. In cirrhosis, patients often present alterations in body composition that are related to adverse outcomes.

New determination of the D0→K -π +π0 and D0→K -π +π +π - coherence factors and average strong-phase d [PDF]

, 2014
Measurements of the coherence factors (RKππ0 and R K3π) and the average strong-phase differences (δDKππ0 and δDK3π) for the decays D0→K -π +π0 and D0→K -π +π +π - are presented.

Correlation of prefrontal cortical activation with changing vehicle speeds in actual driving: a vector-based functional near-infrared spectroscopy study

Frontiers in Human Neuroscience, 2013
Traffic accidents occur more frequently during deceleration than during acceleration. However, little is known about the relationship between brain activation and vehicle acceleration because it has been difficult to measure the brain activation of ...
