Free energy expansions of a conditional GinUE and large deviations of the smallest eigenvalue of the LUE

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 12, Page 2247-2304, December 2025.
Abstract We consider a planar Coulomb gas ensemble of size N$N$ with the inverse temperature β=2$\beta =2$ and external potential Q(z)=|z|2−2clog|z−a|$Q(z)=|z|^2-2c \log |z-a|$, where c>0$c>0$ and a∈C$a \in \mathbb {C}$. Equivalently, this model can be realised as N$N$ eigenvalues of the complex Ginibre matrix of size (c+1)N×(c+1)N$(c+1) N \times (c+1)

Local Wind Speed Forecasting at Short Time Horizons Based on Numerical Weather Prediction and Observations From Surrounding Stations

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract This study presents a hybrid neural network model for short‐term (1–6 hr ahead) surface wind speed forecasting, combining Numerical Weather Prediction (NWP) with observational data from ground weather stations. It relies on the MeteoNet data set, which includes data from global (ARPEGE) and regional (AROME) NWP models of the French weather ...

Nonparametric inference for Poisson‐Laguerre tessellations

open access: yesScandinavian Journal of Statistics, Volume 52, Issue 4, Page 1816-1851, December 2025.
Abstract In this paper, we consider statistical inference for Poisson‐Laguerre tessellations in ℝd$$ {\mathbb{R}}^d $$. The object of interest is a distribution function F$$ F $$ which describes the distribution of the arrival times of the generator points.

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.

Automated measurement of detectability index in CT imaging: Development and validation

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 11, November 2025.
Abstract Purpose The purpose of this study is to develop software for measuring the detectability index (d′) automatically from ACR 464 CT phantom images. Method Software for measuring d′ automatically was developed with Python 3.9.13 using the PyQt5 graphical user interface (GUI) as part of the IndoQCT platform.

Spectral Parameter Power Series for Zakharov‐Shabat Direct and Inverse Scattering Problems

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 14661-14671, 15 November 2025.
ABSTRACT We study the direct and inverse scattering problems for the Zakharov‐Shabat system. Representations for the Jost solutions are obtained in the form of the power series in terms of a transformed spectral parameter. In terms of that parameter, the Jost solutions are convergent power series in the unit disk.

An algorithm and computer program to locate real zeros of real polynomials [PDF]

open access: yes
A method for reliably extracting real zeros of real polynomials using an expanded two-point secant and bisection method is formed into an algorithm for a digital computer, and a computer program based on this algorithm is presented.
