Power beacon-assisted energy harvesting symbiotic radio networks: Outage performance. by Tran Cong Hung, Bui Vu Minh, Tan N Nguyen, Miroslav Voznak

“…Subsequently, we carry out a series of numerical results to verify the developed theory frameworks on the one hand, and on the other hand, analyze the COP performance against the variations of system key parameters (transmit signal-to-noise ratio, the time-splitting coefficient, the energy conversion efficiency factor, the reflection coefficient, and the coexistent decoding threshold). …”

A CEEMDAN-Based Entropy Approach Measuring Multiscale Information Flow between Macroeconomic Conditions and Stock Returns of BRICS by Emmanuel Asafo-Adjei, Anokye Mohammed Adam, Peterson Owusu Junior, Patrick Kwashie Akorsu, Clement Lamboi Arthur

“…We model a mixture of asymmetric and nonlinear bidirectional and unidirectional causality between four macroeconomic variables (exchange rate, GDP, global economic policy uncertainty, and relative CPI) and stock returns of BRICS economies in the frequency-domain using the information flow theory. The Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN)-based Rényi effective transfer entropy approach is used to establish dynamic flow of information between macroeconomic variables and stock returns of BRICS. …”

An estimation of efficiency of filtering algorithms of state vector of small-sized observed object with non-Markovian approximation of trajectory by B. A. Zaikin, A. F. Kotov

“…The introduction discusses the problem consisting in the fact that the use of the approximation of the trajectory of the observed object by Markov processes in some cases can lead to a discrepancy between theory and practice. In the first section, we simulate the trajectories of observed objects when approximated by a Markovian process and indicate the limitations of this approach. …”
