Causes and effects between economically important phenotypic traits in pacu Piaractus mesopotamicus

Aquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
Understand cause and effect relationships between morphometric and carcass traits are fundamental for genetic improvement programs. Uni and multivariate techniques applied to economically important traits in fish; Path analysis is a technique widely used in several areas, however its applications in aquaculture are scarce; Abstract Genetic selection ...

Does Local Bed Shear Stress Predict the Occurrence of Freshwater Mussels?

Ecohydrology, Volume 18, Issue 7, October‐November 2025.
ABSTRACT The relationship between near‐bed hydrodynamics, pore‐water chemistry and the presence of unionids was examined in a well‐characterized multispecies mussel bed (26 species; ~24 mussels m−2; 70% gravel, 20% cobble and 10% sand) within a lowland river (Sydenham River) in southern Ontario, Canada.

Discretization of multiparameter eigenvalue problems

Numerische Mathematik, 1982
Although multiparameter eigenvalue problems, as for example Mathieu's differential equation, have been known for a long time, so far no work has been done on the numerical treatment of these problems. So in this paper we extend the spectral theory for one parameter (cf.

Discrete Chiral Ballistic Polariton Laser

Laser &Photonics Reviews, Volume 19, Issue 15, August 7, 2025.
Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.

Bannai-Ito polynomials and dressing chains [PDF]

, 2013
Schur-Delsarte-Genin (SDG) maps and Bannai-Ito polynomials are studied. SDG maps are related to dressing chains determined by quadratic algebras. The Bannai-Ito polynomials and their kernel polynomials -- the complementary Bannai-Ito polynomials -- are ...

Deep Learning‐Coupled Metabolic Heat Integrated Sensing System for Noninvasive Continuous Monitoring of Blood Glucose

Advanced Intelligent Systems, Volume 7, Issue 5, May 2025.
A portable, wearable device based on metabolic heat integrated sensing and deep learning enables continuous blood glucose (BG) monitoring. The system uses a gate recurrent unit model for real‐time BG prediction, achieving accuracy comparable to commercial noninvasive meters.

Eigenproblem for Jacobi matrices: hypergeometric series solution

, 2006
We study the perturbative power-series expansions of the eigenvalues and eigenvectors of a general tridiagonal (Jacobi) matrix of dimension d. The(small) expansion parameters are being the entries of the two diagonals of length d-1 sandwiching the ...

Volt/VAr Regulation of the West Mediterranean Regional Electrical Grids Using SVC/STATCOM Devices With Neural Network Algorithms

Wind Energy, Volume 28, Issue 2, February 2025.
ABSTRACT Reactive power compensation is now a challenging issue in maintaining adequate power quality and improving the performance of the transmission system. Many researchers have focused on the behavior of voltage in the unbalanced state, and the majority of the studies have been done with STATCOM. In this study, the increasing power demand in power

Simple eigenvalues and bifurcation for a multiparameter problem [PDF]

Proceedings of the Edinburgh Mathematical Society, 1988
We are concerned with the problem of bifurcation of solutions of a non-linear multiparameter problem at a simple eigenvalue of the linearised problem.Let X and Y be real Banach spaces, and let A, Bi, i = 1, …, n∈B(X, Y). Let : Rn × X → Y be a non-linear mapping. We consider the equationwhereand λ=(λ1, λ2,…,λn) ∈ Rn is an n-tuple of spectral parameters.
