Impact of the NCEP TKE‐Based Eddy‐Diffusivity Mass‐Flux Boundary Layer Scheme on the Climatology and Warming Response of GFDL AM4.0 Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract National Centers for Environmental Prediction turbulent kinetic energy (TKE)‐based eddy‐diffusivity mass‐flux (EDMF) scheme is implemented in Geophysical Fluid Dynamics Laboratory atmospheric model (AM4.0) for improving the physical consistency of subgrid‐scale planetary boundary layer (PBL) turbulence parameterization.

Microbiological safety of ungulates meat intended to be frozen and defrosting of frozen ungulates meat

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract Based on the need for a scientific basis for existing requirements in EU legislation on freezing of meat or for its possible amendment, the opinion compares microbial growth of relevant pathogenic, spoilage and indicator microorganisms within five scenarios of chilling, storage and defrosting of bovine, ovine and porcine meat, using predictive

Frequency Response Analysis of State Space Models for Time Series Analysis

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract State space models are well‐suited for time series in which the evolution of variables cannot be well represented by deterministic basis functions. A key challenge in using state space models is the selection of the noise variance parameters. To better understand their impact on the model's filtering behavior, we derive the frequency response ...

Tridiagonal pairs of type III with height one

The Electronic Journal of Linear Algebra, 2019
Let K denote an algebraically closed field with characteristic 0. Let V denote a vector space over K with finite positive dimension, and let A, A∗ denote a tridiagonal pair on V  of diameter d.  Let V0, . . . , Vd  denote a standard ordering of  the eigenspaces of A on V , and let θ0, . . . , θd denote the corresponding eigenvalues of A.

Dispersion of First Sound in a Weakly Interacting Ultracold Fermi Liquid

Annalen der Physik, Volume 537, Issue 11, November 2025.
 The weak‐interaction, low‐temperature region of the phase diagram of a Fermi gas the so‐called Fermi liquid regime, which has been somewhat overlooked in ultracold gases‐is investigated. Precise and measurable predictions are presented for the viscosity and dispersion of first sound to leading order in the scattering length.

A family of tridiagonal pairs related to the quantum affine algebra U_q(sl_2) [PDF]

The Electronic Journal of Linear Algebra, 2005
A type of tridiagonal pair is considered, said to be mild of q-Serre type.It is shown that these tridiagonal pairs induce the structure of a quantum affine algebra Uq( sl2)-module on their underlying vector space.This is done by presenting an explicit basis for the underlying vector space and describing the Uq( sl2)-action on that basis.

A Critical Review of Pole Clustering Techniques: Common Pitfalls, Extension to MIMO and New Enhanced Variant of the Cuckoo Search Algorithm

Optimal Control Applications and Methods, Volume 46, Issue 6, Page 2501-2533, November/December 2025.
Enhanced Cuckoo Search for Model Order Reduction ABSTRACT This article presents a critical review of classical and modern pole clustering techniques for model order reduction in high‐order systems. It highlights key limitations and common pitfalls encountered in traditional approaches, especially when extended to Multi‐Input Multi‐Output (MIMO) systems.

ERF: Energy Research and Forecasting Model

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract High performance computing (HPC) architectures have undergone rapid development in recent years. As a result, established software suites face an ever increasing challenge to remain performant on and portable across modern systems. Many of the widely adopted atmospheric modeling codes cannot fully (or in some cases, at all) leverage the ...

Sensitivity of Perron and Fiedler Eigenpairs to Structural Perturbations of a Network

Numerical Linear Algebra with Applications, Volume 32, Issue 5, October 2025.
ABSTRACT One can estimate the change of the Perron and Fiedler values for a connected network when the weight of an edge is perturbed by analyzing relevant entries of the Perron and Fiedler vectors. This is helpful for identifying edges whose weight perturbation causes the largest change in the Perron and Fiedler values.
