Poisson kernels of q$q$‐3D Hermite polynomials expansion for functions of several variables via generalized q$q$‐heat equations

open access: yesTransactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract The representation of an analytic function as a series involving q$q$‐polynomials is a fundamental problem in classical analysis and approximation theory [Ramanujan J. 19 (2009), no. 3, 281–303]. In this paper, our investigation is focusing on q$q$‐analog complex Hermite polynomials, which were motivated by Ismail and Zhang [Adv. Appl.

Biochar in Animal Agriculture: Enhancing Health, Efficiency and Environmental Sustainability

open access: yesVeterinary Medicine and Science, Volume 11, Issue 6, November 2025.
Biochar enhances animal agriculture by improving gut health (8%–26% higher feed efficiency), reducing methane emissions (up to 22%) and ammonia volatilization (40%–77%) and sequestering carbon. Challenges include variability in quality and economic feasibility, but its integration offers a sustainable path for productivity and environmental stewardship.

Efficacy of Semen Microencapsulation Technique on the Quality of Spermatozoa From Canindé Goats Kept Under Refrigeration for Three Days

open access: yesReproduction in Domestic Animals, Volume 60, Issue 11, November 2025.
ABSTRACT For approximately 40 years, microencapsulation technology has been utilised across various species due to its ability to release semen gradually after artificial insemination. This study aimed to establish the use of the alginate microencapsulation procedure for goat semen and to investigate whether this method enhances longevity during cold ...

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

open access: yesAdvanced Physics Research, Volume 4, Issue 7, July 2025.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Diffusive Equilibrium: Modeling Anisotropic Maxwellian and Kappa Field Line Distributions in Io's Plasma Torus Using Multi‐Fluid and Kinetic Approaches

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Modeling density distributions along Jupiter's magnetic field lines is essential for understanding the Io plasma torus, moon plasma interactions, and plasma throughout the magnetosphere. This study compares multi‐fluid and kinetic approaches to diffusive equilibrium and the effects of different plasma distribution functions and anisotropy.

The Story of Miss C.’s Seduction of Young Women. A Methodological Quest into Female Same‐Sex Relations at the Turn of the Twentieth Century

open access: yesGender &History, Volume 37, Issue 1, Page 267-281, March 2025.
Abstract This article explores a series of newspaper articles from 1908, describing Miss C. – a Copenhagen woman who, apparently, hosted carnal orgies in which she ‘converted’ young women into sapphism. While most historical sources only hint at female same‐sex relationships or describe women's romantic (platonic) feelings for one another, these ...

Higher level appell functions, modular transformations and non-unitary characters [PDF]

open access: yes, 2003
In this thesis, we firstly extend elements and periodicity properties of the theta function theory to functions that represent a wider domain of symmetries and properties, graded with different amounts of p ≥ 1, p ϵ N.

Classical Multiple Orthogonal Polynomials for Arbitrary Number of Weights and Their Explicit Representation

open access: yesStudies in Applied Mathematics, Volume 154, Issue 3, March 2025.
ABSTRACT This paper delves into classical multiple orthogonal polynomials with an arbitrary number of weights, including Jacobi–Piñeiro, Laguerre of both first and second kinds, as well as multiple orthogonal Hermite polynomials. Novel explicit expressions for general recurrence coefficients, as well as the stepline case, are provided for all these ...

Orthogonal Laurent Polynomials of Two Real Variables

open access: yesStudies in Applied Mathematics, Volume 154, Issue 1, January 2025.
ABSTRACT In this paper, we consider an appropriate ordering of the Laurent monomials xiyj$x^{i}y^{j}$, i,j∈Z$i,j \in \mathbb {Z}$ that allows us to study sequences of orthogonal Laurent polynomials of the real variables x$x$ and y$y$ with respect to a positive Borel measure μ$\mu$ defined on R2$\mathbb {R}^2$ such that ({x=0}∪{y=0})∩supp(μ)=∅$(\lbrace ...
