Computational Approaches for Designing Heterostructured Electrocatalysts

open access: yesSmall Science, Volume 5, Issue 5, May 2025.
This review systematically explores computational approaches for modeling and analyzing heterostructures. From a computational materials science perspective, it provides insights into determining heterostructure design types, optimizing lattice strain, and analyzing structural and electronic properties through case studies.

On an integral equation of the Dirichlet problem for the heat equation in the degenerating domain

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
This paper considers the first boundary value problem of heat conduction in a degenerating domain with a moving boundary, the boundary of the domain moves at a variable velocity.

Theoretical Modeling of Secondary Microseisms Considering Source and Receiver Site Structures, With a Focus on Ocean‐Bottom Sediment Effects

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract Opposite‐direction oceanic wave interactions at the ocean surface generate microseisms between 0.1 and ∼ ${\sim} $0.5 Hz, known as secondary microseisms (SM). SM recordings aid in imaging Earth's crust, but they also impede monitoring seismic signals due to tectonic activities.

ROSSMIX 2.0: A Simplified Meso‐Scale Eddy Closure Applied to a Realistic Ocean Model

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 5, May 2025.
Abstract A new closure, ROSSMIX 2.0, for the effect of meso‐scale eddies in non‐eddy‐resolving ocean models is presented and evaluated. It combines aspects of several previous closures in a simplified approach: local linear stability analysis is used to predict the vertical and lateral shape of eddy correlations, while a wave energy equation co ...

Testing covariance separability for continuous functional data

open access: yesJournal of Time Series Analysis, Volume 46, Issue 3, Page 402-420, May 2025.
Analyzing the covariance structure of data is a fundamental task of statistics. While this task is simple for low‐dimensional observations, it becomes challenging for more intricate objects, such as multi‐variate functions. Here, the covariance can be so complex that just saving a non‐parametric estimate is impractical and structural assumptions are ...

Estimating lagged (cross‐)covariance operators of Lp‐m‐approximable processes in Cartesian product Hilbert spaces

open access: yesJournal of Time Series Analysis, Volume 46, Issue 3, Page 582-595, May 2025.
Estimating parameters of functional ARMA, GARCH and invertible processes requires estimating lagged covariance and cross‐covariance operators of Cartesian product Hilbert space‐valued processes. Asymptotic results have been derived in recent years, either less generally or under a strict condition.
