Effects of the Different Dietary Fish Oil Calcium Salt on Production Performance, Blood Biochemical Parameters, Egg Quality Traits and Yolk Fatty Acid Profile in Laying Hens at Peak Production Period

open access: yesVeterinary Medicine and Science, Volume 11, Issue 6, November 2025.
Dietary supplementation with fish oil calcium salt improved laying performance, yolk fatty acid profile and egg quality traits during the peak production period. Higher inclusion levels significantly increased n‐3 PUFA content without negative effects on bird health, while moderate levels (0.75%) optimized performance and productivity.

Genetic Evaluation of Barrel Racing Performance in Quarter Horses

open access: yesJournal of Animal Breeding and Genetics, Volume 142, Issue 6, Page 609-616, November 2025.
ABSTRACT Barrel racing is a competitive timed rodeo event that challenges horses and riders to complete a cloverleaf pattern around three barrels in the fastest time possible. In this study, we aimed to estimate the genetic parameters of barrel racing time (BRT) and evaluate the most suitable statistical model for its analysis.

An expansion theorem concerning Wilson functions and polynomials

open access: yesActa Mathematica Hungarica, 2012
We prove that a relatively general even function f(x) (satisfying a vanishing condition, and also some analyticity and growth conditions) on the real line can be expanded in terms of a certain function series closely related to the Wilson functions introduced by Groenevelt in 2003.

Spectral Analysis of Certain Schrödinger Operators

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
The J-matrix method is extended to difference and q-difference operators and is applied to several explicit differential, difference, q-difference and second order Askey-Wilson type operators.

Addition formulas for q-special functions

open access: yes, 1995
A general addition formula for a two-parameter family of Askey-Wilson polynomials is derived from the quantum $SU(2)$ group theoretic interpretation. This formula contains most of the previously known addition formulas for $q$-Legendre polynomials as ...

The Role of International Trade Agreements During Economic and Policy Crises: Evidence From U.S. Firm Dynamics

open access: yesReview of International Economics, Volume 33, Issue 5, Page 1035-1065, November 2025.
ABSTRACT We use U.S. firm exports from 2003 to 2011 to establish facts about export dynamics in a crisis marked by economic and policy uncertainty. Uncertainty about foreign income, trade protection, and their interaction dampen export investments, which can be partially offset by trade agreements that mitigate policy uncertainty. We find a significant

Estimating the Impact of Impounding an 85‐km2 Hydropower Reservoir in a Subarctic Environment on the Local Radiation Balance

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract This study focuses on the net radiative forcing caused by the impoundment of an 85‐km2 hydroelectric reservoir in the subarctic Côte‐Nord, Quebec, Canada (50.69°N, 63.24°W, mean depth of 44 m). Using spectral bands from the Landsat 7 ETM+ and Landsat 8 OLI/TIRS satellites, we observed spatial and temporal variations in albedo and surface ...
