Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

基于MF-DFA和SVM的齿轮箱故障诊断

Jixie chuandong, 2014
The fault signal of the gearbox is the complex signal of the non-stationary and nonlinear characteristics,by using the multifractal detrended fluctuation analysis（MF-DFA）and the support vector machine（SVM）to diagnose the fault of the gearbox.The ...

Feasibility of Thermal Imaging for Contactless Respiratory Monitoring in Children

Acta Paediatrica, EarlyView.
ABSTRACT Aim Respiratory rate is a key vital sign in paediatric assessment, but accurate measurement in emergency settings is difficult because conventional methods (manual counting, capnography) can be unreliable or impractical. Respiratory rate is frequently omitted in busy emergency departments.

Analysis of global geomagnetic variability [PDF]

Nonlinear Processes in Geophysics, 2007
The orthogonal field components from global INTERMAGNET magnetometer stations are studied via multifractal detrended fluctuation analysis to determine whether there are clear and consistent regional patterns in the behavior of the fluctuations. There are

Detrended fluctuation analysis for heart rate variability analysis

, 2013
Heart rate variability analysis can be used for a diagnosis of the cardiac diseases. The HRV analysis methods are divided into linear and nonlinear methods. Time-domain method is one of the simplest method and belongs to linear methods.
