Reinforcement Learning for Jump‐Diffusions, With Financial Applications
Mathematical Finance, EarlyView.ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

Environmetrics, Volume 37, Issue 3, April 2026.ABSTRACT On April 6, 2009, central Italy was hit by a Mw6.1$$ {M}_w\kern0.3em 6.1 $$ earthquake that caused 308 victims in the city and province of L'Aquila; subsequently, in 2016, two Mw6+$$ {M}_w\kern0.3em 6+ $$ shocks were recorded in an area located a few dozen kilometers further north, respectively in Amatrice and Norcia.

Parameterized coherence measure
Results in Physics, 2023 Quantifying coherence is an essential endeavor for both quantum mechanical foundations and quantum technologies. We present a bona fide measure of quantum coherence by utilizing the Tsallis relative operator (α,β)-entropy.

Kaniadakis Holographic Dark Energy Behavior in f(Q) Theory
Fortschritte der Physik, Volume 74, Issue 4, April 2026.ABSTRACT In this study, the cosmological behavior of the Kaniadakis holographic dark energy model is investigated under the f(Q)$f(Q)$ theory within the framework of a flat Friedmann–Robertson–Walker (FRW) universe. The generalized holographic energy density based on Kaniadakis entropy is modeled using the Hubble horizon infrared cutoff scale, and the ...

Loading Non‐Maxwellian Velocity Distributions in Particle Simulations
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Numerical procedures for generating non‐Maxwellian velocity distributions in particle simulations are presented. First, Monte Carlo methods for the (r,q) $(r,q)$ distribution that generalizes flattop and Kappa distributions are discussed. Then, two rejection methods for the regularized Kappa distribution are presented, followed by a comparison

Pathway Model, Superstatistics, Tsallis Statistics, and a Generalized Measure of Entropy
, 2006 The pathway model of Mathai (2005) is shown to be inferable from the maximization of a certain generalized entropy measure. This entropy is a variant of the generalized entropy of order 'alpha', considered in Mathai and Rathie (1975), and it is also ...

Quantum Machine Learning Applications to Medical Images: A Survey
IET Quantum Communication, Volume 7, Issue 1, January/December 2026.In this review paper, we provide an outline of quantum neural networks (QNNs), quantum convolution neural networks (QCNNs) and various hybrid models. We also explore human brain‐inspired quantum neuromorphic computing by the quantum spiking neural networks (QSNN).
