An Optimized Block Hybrid Spectral Simple Iteration Methods for Solving Nonlinear Evolution Equations

International Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.
ABSTRACT This study presents a new optimized block hybrid method and spectral simple iteration method (OBHM‐SSIM) for solving nonlinear evolution equations. In this method, we employed a combination of the spectral collocation method in space and the optimized block hybrid method in time, along with a simple iteration scheme to linearize the equations.

Learning Low‐Dimensional Representations of Ensemble Forecast Fields Using Autoencoder‐Based Methods

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Large‐scale numerical simulations often produce high‐dimensional gridded data, which is challenging to process for downstream applications. A prime example is numerical weather prediction, where atmospheric processes are modeled using discrete gridded representations of the physical variables and dynamics. Uncertainties are assessed by running

A New Generalization of Bivariate Sampling Kantorovich Operators and Applications to Image Processing

Mathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 15413-15432, 15 November 2025.
ABSTRACT In this paper, we introduce bivariate modified sampling Kantorovich operators, which extend the classical sampling Kantorovich operators by incorporating a transformation function ρ$$ \rho $$. The paper begins by presenting essential definitions, including to introduce new bivariate weighted modulus of continuity, and its fundamental ...

From Inception to Innovation: 20 Years of Nanoarchitectonics

Chemistry – An Asian Journal, Volume 20, Issue 20, October 17, 2025.
Although nanotechnology was founded in the 20th century, the term nanoarchitectonics was first coined at the turn of the 21st century. Therefore, nanoarchitectonics has a history of about 20 years. In this review article, we will provide an overview of nanoarchitectonics through examining some research examples on manipulation‐based nanoarchitectonics ...

Putinism and the End of the Taboo on Land Grabs in Russian Politics: An Insight into the Territorial Aspect of the Ideology

The Russian Review, Volume 84, Issue 4, Page 593-611, October 2025.
Abstract Putinist ideology is not merely a project of a narrow political elite, but rather a set of ideas that hold domestic appeal. The ideologized vision of Russia fighting for its rightful place in the international arena has resonated with mass social grievances created by the fall of the USSR.

Approximation by ψ‐Baskakov‐Kantorovich Operators

Mathematical Methods in the Applied Sciences, Volume 48, Issue 14, Page 13552-13562, 30 September 2025.
ABSTRACT In this paper, we introduce a new family of Baskakov‐Kantorovich operators that depend on a function ψ$$ \psi $$. We compare these new ψ$$ \psi $$‐Baskakov‐Kantorovich operators with the classical Baskakov‐Kantorovich operators to evaluate their approximation results.

Action functional as an early warning indicator in the space of probability measures via Schrödinger bridge

Quantitative Biology, Volume 13, Issue 3, September 2025.
Abstract Critical transitions and tipping phenomena between two meta‐stable states in stochastic dynamical systems are a scientific issue. In this work, we expand the methodology of identifying the most probable transition pathway between two meta‐stable states with Onsager–Machlup action functional, to investigate the evolutionary transition dynamics ...

Multivariate Neural Network Operators: Simultaneous Approximation and Voronovskaja‐Type Theorem

Mathematical Methods in the Applied Sciences, Volume 48, Issue 11, Page 10669-10677, 30 July 2025.
ABSTRACT In this paper, the simultaneous approximation and a Voronoskaja‐type theorem for the multivariate neural network operators of the Kantorovich type have been proved. In order to establish such results, a suitable multivariate Strang–Fix type condition has been assumed.

Spatial verification of global precipitation forecasts

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 771, July 2025 Part B.
We present an adaptation of the recently developed precipitation attribution distance (PAD) metric, designed for verifying precipitation, enabling its use on the Earth's spherical geometry. The method is fast and flexible, with its behavior analyzed using a set of idealized cases and 7 years of operational global high‐resolution precipitation forecasts.

A Novel Dual‐Network Approach for Real‐Time Liveweight Estimation in Precision Livestock Management

Advanced Science, Volume 12, Issue 22, June 12, 2025.
A novel dual‐network framework is proposed for real‐time, non‐contact liveweight estimation of pigs. By extracting contour information instead of segmented images, the method achieves high accuracy (R2 = 0.993) and an exceptional speed of 1131.6 FPS. This approach enhances automation in livestock farming, providing a scalable and efficient solution for
