Measures of the direction and strength of the interdependence among time series from multivariate systems are evaluated based on their statistical significance and discrimination ability. The best-known measures estimating direct causal effects, both linear and nonlinear, are considered, i.e., conditional Granger causality index (CGCI), partial Granger causality index (PGCI), partial directed c...

Polarized light imaging is a potential tool to obtain an adequate description of the properties of depolarizing media such as biological tissues. In many biomedical applications, for instance, dermatology, ophthalmology, or urology, imaging polarimetry provides a noninvasive diagnosis of a wide range of disease states, and, likewise, it could be applied to the study of internal tissues though t...

In a driven open quantum system, the relation between heat and dynamical phase, suppression of coherence creation without use counterdiabatic drive, entropy preserving nonunitary operation are presented. An experimental setup with superconducting circuit is proposed.

Synchronization or phase-locking between oscillating neuronal groups is considered to be important for coordination of information among cortical networks. Spectral coherence is a commonly used approach to quantify phase locking between neural signals. We systematically explored the validity of spectral coherence measures for quantifying synchronization among neural oscillators. To that aim, we...

σ ⊗n is given by a regularized quantum relative entropy distance formula. We prove that in general such a regularization is needed but also discuss various settings where our formula as well as extensions thereof become single-letter. This includes a novel operational interpretation of the relative entropy of coherence in terms of hypothesis testing. For our proof, we start from the composite S...

In this paper our recent investigation and experimental results of the polarimetric SAR classification of the data for the Glen Affric radar project is presented. The polarimetric classification is one of the most important applications of the radar polarimetry in remote sensing. The unsupervised and supervised polarimetric classification of the Glen Affric data in respect to the classified Ari...

Nucleic acids theoretically possess a Szilard engine function that can convert the energy associated with the Shannon entropy of molecules for which they have coded recognition, into the useful work of geometric reconfiguration of the nucleic acid molecule. This function is logically reversible because its mechanism is literally and physically constructed out of the information necessary to red...

For a wide range of entropy measures, easy calculation of equilibria is possible using a principle of Game Theoretical Equilibrium related to Jaynes Maximum Entropy Principle. This follows previous work of the author and relates to Naudts [1], [2], and, partly, Abe and Bagci [3].

The aim of this work is to answer the question how much quantum coherence a beam splitter able produce. To end we consider as variables under study both amount input states well characteristics. We conclude that there an optimal combination these factors making gain maximum. In addition, two mode squeezed vacuum arises studied state most capable gaining when passing through splitter. These resu...
