Recurrence Quantification Analysis as a Form of Postural Control Assessment: A Systematic Review

open access: yesApplied Sciences (Switzerland), 2023
Human postural control is commonly assessed by center of pressure (CoP) displacement analysis. However, traditional linear parameters do not provide a complete picture of postural control, so a number of nonlinear analyses have been introduced.

Recurrence Quantification Analysis (RQA) of Toroidal End Tool Milling Process

open access: yesApplied Sciences (Switzerland)
One type of milling process is the face milling of flat surfaces using a toroidal face cutter. A key feature of this process is that changes in the depth of the cut alter the entering angle, impacting milling dynamics by shifting cutting force ...

Diabetes alters cardiorespiratory dynamics: insights from short-term recurrence quantification analysis of pulse-respiration quotient [PDF]

open access: yesFrontiers in Physiology
IntroductionThe Pulse-Respiration Quotient (PRQ) is considered a powerful tool for assessing dynamic interactions between cardiac and respiratory rhythms. Type 2 diabetes mellitus (T2DM) disrupts autonomic control, potentially compromising the complexity
