Laser-engraved holograms as entropy source for random number generators

open access: yesMicro and Nano Engineering
Our study introduces a novel approach to true random number generation (TRNG) using speckle patterns generated by laser-engraved holograms on carbon fiber-reinforced polymer (CFRP) composite substrates.

Typical and extreme entropies of long-lived isolated quantum systems

open access: yes, 2020
In this paper, we investigate and compare two well-developed definitions of entropy relevant for describing the dynamics of isolated quantum systems: bipartite entanglement entropy and observational entropy.

On the Existence of the Logarithmic Correction Term in Black Hole Entropy-Area Relation [PDF]

open access: yes, 2006
In this paper we consider a model universe with large extra dimensions to obtain a modified black hole entropy-area relation. We use the generalized uncertainty principle to find a relation between the number of spacetime dimensions and the presence or ...

The Evaluation of Entropy-based Algorithm towards the Production of Closed-Loop Edge

open access: yesJOIV: International Journal on Informatics Visualization, 2023
This research concerns the common problem of edge detection that produces a disjointed and incomplete edge, leading to the misdetection of visual objects.

Complementarity in atomic and oscillator systems

open access: yes, 2010
We develop a unified, information theoretic interpretation of the number-phase complementarity that is applicable both to finite-dimensional (atomic) and infinite-dimensional (oscillator) systems. The relevant uncertainty principle is obtained as a lower

Entropy numbers in ‐Banach spaces

open access: yesMathematische Nachrichten, 2017
AbstractLet X be a quasi‐Banach space, Y be a γ‐Banach space and T be a bounded linear operator from X into Y. In this paper, we prove that the first outer entropy number of T lies between and ; more precisely, , and the constant is sharp. Moreover, we show that there exist a Banach space X0, a γ‐Banach space Y0 and a bounded linear operator such ...

Entropy dissipation estimates in a Zero-Range dynamics

open access: yes, 2006
We study the exponential decay of relative entropy functionals for zero-range processes on the complete graph. For the standard model with rates increasing at infinity we prove entropy dissipation estimates, uniformly over the number of particles and the

Non-extremal Stringy Black Hole [PDF]

open access: yes, 1996
We construct a four-dimensional BPS saturated heterotic string solution from the Taub-NUT solution. It is a non-extremal black hole solution since its Euler number is non-zero. We evaluate its black hole entropy semiclassically.

Entropy generation under the influence of radial magnetic field and viscous dissipation of generalized Couette flow in an annulus

open access: yesPropulsion and Power Research, 2018
This paper investigates the combined effect of radial magnetic field and viscous dissipation on entropy generation in horizontal co-axial cylinders of generalized Couette flow.

Bio-Inspired Intelligent Systems: Negotiations between Minimum Manifest Task Entropy and Maximum Latent System Entropy in Changing Environments

open access: yesEntropy, 2023
In theoretical physics and theoretical neuroscience, increased intelligence is associated with increased entropy, which entails potential access to an increased number of states that could facilitate adaptive behavior. Potential to access a larger number
