Clifford Wavelet Entropy for Fetal ECG Extraction
Entropy, 2021 Analysis of the fetal heart rate during pregnancy is essential for monitoring the proper development of the fetus. Current fetal heart monitoring techniques lack the accuracy in fetal heart rate monitoring and features acquisition, resulting in ...

On Tools for Completeness of Kleene Algebra with Hypotheses [PDF]
International Conference on Relational and Algebraic Methods in Computer Science, 2022 In the literature on Kleene algebra, a number of variants have been proposed which impose additional structure specified by a theory, such as Kleene algebra with tests (KAT) and the recent Kleene algebra with observations (KAO), or make specific ...

On L-derivatives and biextensions of Calabi–Yau motives
Experimental Results, 2023 We prove that certain differential operators of the form $ DLD $ with $ L $ hypergeometric and $ D=z\frac{\partial }{dz} $ are of Picard–Fuchs type.

The Systematic Risk at the Crisis—A Multifractal Non-Uniform Wavelet Systematic Risk Estimation
Fractal and Fractional, 2021 In the last decade, many factors, such as socio-political and econo-environmental ones, have led to a perturbation in the timeline of the worldwide development, and especially in countries and regions having political changes.

Renormalization in Combinatorially Non-Local Field Theories: The Hopf Algebra of 2-Graphs [PDF]
Mathematical physics, analysis and geometry, 2021 Renormalization in perturbative quantum field theory is based on a Hopf algebra of Feynman diagrams. A precondition for this is locality. Therefore one might suspect that non-local field theories such as matrix or tensor field theories cannot benefit ...

Wrońskian algebra and Broadhurst–Roberts quadratic relations [PDF]
Communications in Number Theory and Physics, 2020 Through algebraic manipulations on Wronskian matrices whose entries are reducible to Bessel moments, we present a new analytic proof of the quadratic relations conjectured by Broadhurst and Roberts, along with some generalizations.
