EcoMat, Volume 7, Issue 7, July 2025.Focusing on the black‐box problem in the battery field, this review provides an introduction to dynamic electrochemical impedance spectroscopy (DEIS), an emerging nondestructive testing technique. It first systematically explains the fundamental principles of DEIS and its analytical methods. Then, it explores its applications across four key areas: (1)

Water Resources Research, Volume 61, Issue 6, June 2025.Abstract Groundwater (GW) is the primary water source of socio‐economic development in water‐deficient regions, and long‐term overexploitation may cause GW depletion and deterioration. In this study, after analyzing the relationship between GW level and related factors, the main influencing factors were identified from the perspective of climate change

Randomly pivoted Cholesky: Practical approximation of a kernel matrix with few entry evaluations
Communications on Pure and Applied Mathematics, Volume 78, Issue 5, Page 995-1041, May 2025.Abstract The randomly pivoted Cholesky algorithm (RPCholesky) computes a factorized rank‐k$k$ approximation of an N×N$N \times N$ positive‐semidefinite (psd) matrix. RPCholesky requires only (k+1)N$(k + 1)N$ entry evaluations and O(k2N)$\mathcal {O}(k^2 N)$ additional arithmetic operations, and it can be implemented with just a few lines of code.

Ridge regularized estimation of VAR models for inference
Journal of Time Series Analysis, Volume 46, Issue 2, Page 235-257, March 2025.Ridge regression is a popular method for dense least squares regularization. In this article, ridge regression is studied in the context of VAR model estimation and inference. The implications of anisotropic penalization are discussed, and a comparison is made with Bayesian ridge‐type estimators.
