Quantum Machine Learning Applications to Medical Images: A Survey

open access: yesIET 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).

A note on operator inequalities of Tsallis relative operator entropy [PDF]

open access: yes, 2005
Tsallis relative operator entropy was defined as a parametric extension of relative operator entropy and the generalized Shannon inequalities were shown in the previous paper.

Examining Oil Prices for Chaos, Entropy, Fractionality and Complexity, and Modeling the Impacts of Economic Policy Uncertainty and Geopolitical Risks: GARCH–MIDAS–LSTM Approach

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
As the leading energy source, oil price volatility has crucial effects in energy markets, and geopolitical risks (GPRs) and economic policy uncertainties contribute to its volatility. Further, chaos, long‐range dependence, fractionality, and complexity significantly reduce modeling and forecast performances.

Comprehensive Characterizations, Information Measures, and Reliability Applications for the Yun–Linear Exponential Lifetime Model

open access: yesAxioms
We propose the three-parameter Yun–Linear Exponential (YLE) distribution, with a specific focus on its comprehensive characterizations based on truncated moments, hazard functions, and conditional expectations.

Entropy in Hydrology

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Although the concept of thermodynamic entropy due to Clausius dates back to the early 1850s, the mathematical theory of informational entropy was not developed until the pioneering work of Shannon in 1948, the development of principle of maximum entropy (POME) and theorem of concentration by Jaynes in 1957, principle of minimum cross entropy ...

Comment on “Thermodynamic stability conditions for the Tsallis and Rényi entropies” by J.D. Ramshaw

open access: yesPhysics Letters A, 1995
Abstract Ramshaw [Phys. Lett. A 198 (1995) 119] has recently shown that if one considers the generalized entropy S q ≡k (1−∑ i p i q ) (q−1) (q ∈ R ; q = 1 corresponds to standard thermostatistics) and the standard internal energy U1≡∑ipiϵi, then thermodynamic stability of the system is not guaranteed for all values

Searching for Universality of Turbulence in the Earth's Magnetosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Turbulence in space plasmas remains a fundamental challenge, and Earth's magnetosphere (MSP) offers a natural laboratory for its study. Using high‐resolution magnetic field data from the Magnetospheric Multiscale (MMS) mission, we extend a stochastic Markovian framework to analyze turbulence across 10 diverse magnetospheric regions, including ...
