Genetic diversity derived from pedigree information and estimation of genetic parameters for reproductive traits of Limousine and Charolais cattle raised in Italy

open access: yesItalian Journal of Animal Science, 2020
Limousine and Charolais cattle breeds are assuming increasing importance in the Italian beef cattle sector. Indeed, both breeds are involved in a national rural development project.

Sperm Quality in Young Bull Semen Can Be Improved by Single Layer Centrifugation

open access: yesAnimals, 2022
Interest in using semen from young bulls is increasing due to identifying promising animals by genomic selection. However, sperm quality in these ejaculates may not reach currently accepted standards for the cattle breeding industry.

Generalizing the KYP lemma to the union of intervals [PDF]

open access: yes2013 European Control Conference (ECC), 2013
A recent generalization of the Kalman-Yakubovich-Popov (KYP) lemma establishes the equivalence between a semi-infinite inequality on a segment of a circle or straight line in the complex plane and a linear matrix inequality. In this paper we further generalize the KYP lemma to particular curves in the complex plane, which include the union of segments ...

Population structure of Brazilian Gyr dairy cattle Estrutura populacional de bovinos Gir leiteiros no Brasil

open access: yesRevista Brasileira de Zootecnia, 2010
The objective of the present study was to evaluate the genetic structure of Gyr cattle selected for milk production. Files of pedigree and production were composed of 27,610 animals. The ENDOG program was used for the calculation of individual inbreeding

A Domain of Spacetime Intervals in General Relativity [PDF]

open access: yesCommunications in Mathematical Physics, 2006
We prove that a globally hyperbolic spacetime with its causality relation is a bicontinuous poset whose interval topology is the manifold topology. This implies that from only a countable dense set of events and the causality relation, it is possible to reconstruct a globally hyperbolic spacetime in a purely order theoretic manner.

Interval MV-algebras and generalizations

open access: yesInternational Journal of Approximate Reasoning, 2014
For any MV-algebra $A$ we equip the set $I(A)$ of intervals in $A$ with pointwise Łukasiewicz negation $\neg x=\{\neg α\mid α\in x\}$, (truncated) Minkowski sum, $x\oplus y=\{α\oplus β\mid α\in x,\,\,β\in y\}$, pointwise Łukasiewicz conjunction $x\odot y=\neg(\neg x\oplus \neg y)$, the operators $Δx=[\min x,\min x]$, $\nabla x=[\max x,\max x]$, and ...

On the Generating Function for Intervals in Young's Lattice

open access: yesThe Electronic Journal of Combinatorics, 2023
In this paper, we study a family of generating functions whose coefficients are polynomials that enumerate partitions in lower order ideals of Young's lattice. Our main result is that this family satisfies a rational recursion and are therefore rational functions.

Pedigree analysis of the Latvian Warmblood horse heavy type population

open access: yesCzech Journal of Animal Science
A breeding program has been developed for the Latvian warmblood heavy type horses in Latvia, with the aim to preserve this type, because the number of these horses is small and the status of the local endangered breed has been granted.
