Cascading CMOS-Based Chaotic Maps for Improved Performance and Its Application in Efficient RNG Design

open access: yesIEEE Access, 2022
We present a general framework for improving the chaotic properties of CMOS-based chaotic maps by cascading multiple maps in series. Along with two novel chaotic map topologies, we present the 45 $nm$ designs for four CMOS-based discrete-time chaotic ...

Ve-Degree, Ev-Degree, and Degree-Based Topological Indices of Fenofibrate

open access: yesJournal of Mathematics, 2022
The molecular topology of a graph is described by topological indices, which are numerical measures. In theoretical chemistry, topological indices are numerical quantities that are used to represent the molecular topology of networks.

Algebraic Structure Graphs over the Commutative Ring Zm: Exploring Topological Indices and Entropies Using M-Polynomials

open access: yesMathematics, 2023
The field of mathematics that studies the relationship between algebraic structures and graphs is known as algebraic graph theory. It incorporates concepts from graph theory, which examines the characteristics and topology of graphs, with those from ...

Effective entropy of quantum fields coupled with gravity

open access: yesJournal of High Energy Physics, 2020
Entanglement entropy, or von Neumann entropy, quantifies the amount of uncertainty of a quantum state. For quantum fields in curved space, entanglement entropy of the quantum field theory degrees of freedom is well-defined for a fixed background geometry.

Vertex-Based Topological Indices of Double and Strong Double Graph of Dutch Windmill Graph

open access: yesJournal of Chemistry, 2021
A measurement of the molecular topology of graphs is known as a topological index, and several physical and chemical properties such as heat formation, boiling point, vaporization, enthalpy, and entropy are used to characterize them.

A morphospace of functional configuration to assess configural breadth based on brain functional networks

open access: yesNetwork Neuroscience, 2021
The quantification of human brain functional (re)configurations across varying cognitive demands remains an unresolved topic. We propose that such functional configurations may be categorized into three different types: (a) network configural breadth, (b)

Entropy of constant curvature black holes in general relativity [PDF]

open access: yes, 1997
We consider the thermodynamic properties of the constant curvature black hole solution recently found by Banados. We show that it is possible to compute the entropy and the quasilocal thermo- dynamics of the spacetime using the Einstein-Hilbert action of

The generalized entropy in the generalized topological spaces

open access: yesTopology and its Applications, 2012
The authors study the generalized entropy of selfmaps, multi-selfmaps and selfmaps of the power set of a generalized topological space. They also establish a connection between generalized and standard entropy for usual selfmaps of a compact metric space and they show that the generalized entropy is a lower estimate of the standard entropy.
