An active contour model for texture image segmentation using Rényi divergence measure
Mathematical Modelling and Analysis, 2022 This paper proposes an efficient method for active unsupervised texture segmentation. A new descriptor for texture features extractions based on Gaussian and mean curvature is constructed.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies
Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Random Structures &Algorithms, Volume 69, Issue 1, August 2026.ABSTRACT Systems of interacting trajectories were recently studied in Hermann et al. (2025). Such a system of [0,1]$$ \left[0,1\right] $$‐valued piecewise linear trajectories arises as a scaling limit of the system of logarithmic subpopulation sizes in a population‐genetic model (more precisely, a Moran model) with mutation and selection. By definition,

On Metric Choice in Dimension Reduction for Fréchet Regression
International Statistical Review, Volume 94, Issue 2, Page 325-346, August 2026.Summary Fréchet regression is becoming a mainstay in modern data analysis for analysing non‐traditional data types belonging to general metric spaces. This novel regression method is especially useful in the analysis of complex health data such as continuous monitoring and imaging data.

The number of regular simplices in higher dimensions
Bulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.Abstract We study the extremal function Sdk(n)$S^k_d(n)$, defined as the maximum number of regular (k−1)$(k-1)$‐simplices spanned by n$n$ points in Rd$\mathbb {R}^d$. For any fixed d⩾2k⩾6$d\geqslant 2k\geqslant 6$, we determine the asymptotic behavior of Sdk(n)$S^k_d(n)$ up to a lower‐order term.

Finding an almost perfect matching in a hypergraph avoiding forbidden submatchings
Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.Abstract In 1973, Erdős conjectured the existence of high girth (n,3,2)$(n,3,2)$‐Steiner systems. Recently, Glock, Kühn, Lo, and Osthus and independently Bohman and Warnke proved the approximate version of Erdős' conjecture. Recently, Kwan, Sah, Sawhney, and Simkin proved Erdős' conjecture.

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory
Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 4, July/August 2026.ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

A measure of mutual divergence among a number of probability distributions
International Journal of Mathematics and Mathematical Sciences, 1987 The principle of optimality of dynamic programming is used to prove three major inequalities due to Shannon, Renyi and Holder. The inequalities are then used to obtain some useful results in information theory.

Conditional Rényi Divergence Saddlepoint and the Maximization of α-Mutual Information
Entropy, 2019 Rényi-type generalizations of entropy, relative entropy and mutual information have found numerous applications throughout information theory and beyond. While there is consensus that the ways A.
