Holographic studies of Einsteinian cubic gravity

open access: yes, 2018
Einsteinian cubic gravity provides a holographic toy model of a nonsupersymmetric CFT in three dimensions, analogous to the one defined by Quasi-topological gravity in four. The theory admits explicit non-hairy AdS$_4$ black holes and allows for numerous

Rényi entanglement entropy of Fermi and non-Fermi liquids: Sachdev-Ye-Kitaev model and dynamical mean field theories

open access: yesPhysical Review Research, 2020
We present a method for calculating Rényi entanglement entropies for fermionic field theories originating from microscopic Hamiltonians. The method builds on an operator identity, which leads to the representation of traces of operator products, and thus

RTransferEntropy — Quantifying information flow between different time series using effective transfer entropy

open access: yesSoftwareX, 2019
This paper shows how to quantify and test for the information flow between two time series with Shannon transfer entropy and Rényi transfer entropy using the R package RTransferEntropy. We discuss the methodology, the bias correction applied to calculate

Mathematical Modeling of Amoxicillin Synthesis in Batch and Semi‐Batch Reactor: Application of Bayesian Statistics and Genetic Algorithm

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 1, Page 104-115, January 2026.
Synthesis of amoxicillin: The reaction catalyzed by penicillin G acylase is investigated in an enzymatic reactor, considering both Michaelis–Menten and mechanism‐based models with reaction and equilibrium constants. Parameters are estimated via MCMC and Genetic Algorithm, with MCMC showing superior performance in validating the mathematical model in a ...

Eigen solutions of the Schrӧdinger equation and the thermodynamic stability of the black hole temperature

open access: yesResults in Physics, 2018
The approximate analytical solutions of the Schrӧdinger equation for Eckart potential is obtained via supersymmetry shape invariance approach. The energy equation and the corresponding wave function are obtained in a closed and compact form.

A Survey of SIR‐Based Differential Epidemic Models for Control and Security Against Malware Propagation in Computer Networks

open access: yesSECURITY AND PRIVACY, Volume 9, Issue 1, January/February 2026.
ABSTRACT Unarguably, malware and their variants have metamorphosed into objects of attack and cyber warfare. These issues have directed research focus to modeling infrastructural settings and infection scenarios, analyzing propagation mechanisms, and conducting studies that highlight optimized remedial measures.

Robust Active Contour Model for Image Segmentation Using a Probability Density Function Approach

open access: yesIET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper proposes an active contour model‐based image segmentation algorithm using the probability density function. Initially, the probability density function is defined by the local mean and variance. Next, a length penalty term and a distance regularization term are incorporated.

Two Measures of Dependence

open access: yes, 2019
Two families of dependence measures between random variables are introduced. They are based on the R\'enyi divergence of order $\alpha$ and the relative $\alpha$-entropy, respectively, and both dependence measures reduce to Shannon's mutual information ...

Multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals

open access: yesJournal of High Energy Physics
We study multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals. The Rényi entropy evaluation involves computing the partition function of the theory on Riemann surfaces with genus g > 1.

Dynamical entropic measure of nonclassicality of phase-dependent family of Schrödinger cat states

open access: yesScientific Reports, 2023
The phase-space approach based on the Wigner distribution function is used to study the quantum dynamics of the three families of the Schrödinger cat states identified as the even, odd, and Yurke–Stoler states.
