Rescaled Range Analysis and Detrended Fluctuation Analysis: Finite Sample Properties and Confidence Intervals [PDF]
We focus on finite sample properties of two mostly used methods of Hurst exponent H estimation—rescaled range analysis (R/S) and detrended fluctuation analysis (DFA).

Journal of Personality, EarlyView.ABSTRACT Objective Schizotypal personality traits, such as unusual experiences, odd beliefs, or social anhedonia, predict psychotic‐like experiences (PLEs) and heightened stress‐reactivity in daily life. Yet, in previous studies, stressor appraisal, but not exposure, was used to predict stress‐reactivity, which might be a consequence of behavioral ...

Journal of Sleep Research, EarlyView.ABSTRACT Obstructive sleep apnoea (OSA) is a highly prevalent but heterogeneous condition which makes identifying patients at risk of vigilance and driving impairment clinically challenging. Resting wake electroencephalography (EEG) is associated with vigilance performance in healthy participants.

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep
Journal of Sleep Research, EarlyView.ABSTRACT Wake/sleep‐related changes in cerebral hemodynamic oscillations are well established, but similar changes in peripheral hemodynamics remain largely understudied. Moreover, how the relationship between cerebral and peripheral hemodynamics varies across sleep–wake states is not well understood, despite evidence that these oscillations in the low‐
