Convergence properties of dynamic mode decomposition for analytic interval maps
Communications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 179-206, February 2026.Abstract Extended dynamic mode decomposition (EDMD) is a data‐driven algorithm for approximating spectral data of the Koopman operator associated to a dynamical system, combining a Galerkin method with N$N$ functions and a quadrature method with M$M$ quadrature nodes.

Large‐Scale Genotype‐Based Trait Imputation With Multi‐Ancestry GWAS Data
Genetic Epidemiology, Volume 50, Issue 1, February 2026.ABSTRACT Genome‐wide association studies (GWAS) have been instrumental in identifying genetic variants associated with complex traits and diseases, including Alzheimer's disease (AD). However, traditional GWAS approaches often focus on European populations, which may lead to loss of power and limit the generalizability of findings across diverse ...

Novel Methods for Computing the Moore-Penrose Inverse of Neutrosophic Fuzzy Matrices [PDF]
Neutrosophic Sets and SystemsIn this paper, we introduce a method for determining the generalized inverse (g-inverse) and the Moore-Penrose inverse of Neutrosophic Fuzzy Matrices (NFMs), along with the necessary conditions.

Definition and Computation of Tensor‐Based Generalized Function Composition
Numerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.ABSTRACT Functions are fundamental to mathematics as they offer a structured and analytical framework to express relations between variables. While scalar and matrix‐based functions are well‐established, higher‐order tensor‐based functions have not been as extensively explored.

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

On an inequality related to the volume of a parallelepiped
Examples and CounterexamplesThe problem of establishing an upper bound for the volume of a parallelepiped is considered by utilizing an original approach involving a skew-symmetric matrix of order four (along with its Moore–Penrose inverse).

Predictive signal modeling and multi‐rate filtering in accelerated cardiac MRI
Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 585-600, January 2026.Abstract Purpose True real‐time cardiac MRI (CMR), necessary for capturing live cardiac dynamics and imaging irregular cardiac rhythms, remains challenging. In this article, we move toward real‐time CMR in multiple reconstruction frameworks via strategies to predict cardiac motion, improve computational efficiency, reduce artifacts, and preserve ...

Loop Matching Pursuit Multistation TDOA Estimation Method Based on Noncircular Signal
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.The existing TDOA estimation methods based on orthogonal matching pursuit only consider the scenario of circular signal and are prone to the degradation of estimation performance due to atom misselection under small samples and low signal‐to‐noise ratio.
