Approximate Entropy and Sample Entropy are two algorithms for determining the regularity
of series of data based on the existence of patterns. Despite their similarities, the theoretical …

Characteristic patterns of variation over time, namely rhythms, represent a defining feature of
complex systems, one that is synonymous with life. Despite the intrinsic dynamic …

Fuzzy entropy (FuzzyEn), a new measure of time series regularity, was proposed and
applied to the characterization of surface electromyography (EMG) signals. Similar to the two …

This paper compares three related measures of complexity, ApEn, SampEn, and FuzzyEn.
Since vectors' similarity is defined on the basis of the hard and sensitive boundary of …

Panic disorder and agoraphobia tend to be chronic conditions, often with an unremitting
course, considerable social, occupational, and physical disability, and high rates of …

Calculation of approximate entropy (ApEn) requires a priori determination of two unknown
parameters, m and r. While the recommended values of r, in the range of 0.1-0.2 times the …

BACKGROUND: Given growing evidence that respiratory dysregulation is a central feature
of panic disorder (PD) interventions for panic that specifically target respiratory functions …

Anxiety disorders, particularly panic disorder (PD), are associated with respiratory
abnormalities. PD consists of unexpected panic attacks (PA) with anxiety, fear and many …

A defining but elusive feature of the human brain is its astonishing complexity. This
complexity arises from the interaction of numerous neuronal circuits that operate over a wide …
