Abstract We prove the existence of a universal recovery channel that approximately recovers states on von Neumann subalgebra when change in relative entropy, with respect to fixed reference state, is small. Our result generalization previous results applied type-I algebras by Junge at al. [ arXiv:1509.07127 ]. broadly follow their proof strategy but consider here arbitrary algebras, where quali...

Driver fatigue has become an important factor to traffic accidents worldwide, and effective detection of driver fatigue has major significance for public health. The purpose method employs entropy measures for feature extraction from a single electroencephalogram (EEG) channel. Four types of entropies measures, sample entropy (SE), fuzzy entropy (FE), approximate entropy (AE), and spectral entr...

Left ventricular dyssynchrony can be assessed with phase parameters from radionuclide ventriculography (RNVG), including approximate entropy (ApEn). The input values used to calculate ApEn will affect the results significantly, so it is essential optimise for application. However date, no optimisation applied images has been published. In this paper, generated data were simulate patient images,...

In this paper, we derive a new generalisation of the strong subadditivity entropy to setting general conditional expectations onto arbitrary finite-dimensional von Neumann algebras. The latter inequality, which call approximate tensorization relative entropy, can be expressed as lower bound for sum entropies between given density and its respective projections two intersecting algebras in terms...

1. Investigations that assess cardiac autonomic function include non-linear techniques such as fractal dimension and approximate entropy in addition to the common time and frequency domain measures of both heart period and heart rate. This article evaluates the differences in using heart rate versus heart period to estimate fractal dimensions and approximate entropies of these time series.2. Tw...

1. Introduction Hormones, such as luteinizing hormone (LH), are secreted into the blood in short bursts, called pulses, and removed by a decay process. Using hormone assays from blood samples obtained at equally spaced intervals, investigators study secretion characteristics such as pulse frequency and amplitude to learn whether various diseases affect hormone secretion. Approximate entropy (Ap...

OBJECTIVES This study evaluated oculometrics as a detector of fatigue in Air Force-relevant tasks after sleep deprivation. Using the metrics of total eye closure duration (PERCLOS) and approximate entropy (ApEn), the relation between these eye metrics and fatigue-induced performance decrements was investigated. BACKGROUND One damaging effect to the successful outcome of operational military m...
