Changes in genetic trends in US dairy cattle since the implementation of genomic selection

open access: yesJournal of Dairy Science, 2023
: Genomic selection increases accuracy and decreases generation interval, accelerating genetic changes in populations. Assumptions of genetic improvement must be addressed to quantify the magnitude and direction of change.

N-qubit entanglement via the $J_y^2$-type collective interaction [PDF]

open access: yes, 2005
We investigate quantum correlations of the $N$-qubit states via a collective pseudo-spin interaction ($\propto J_y^2$) on arbitrary pure separable states for a given interval of time.

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 ukasiewicz negation $\neg x=\{\neg \mid \in x\}$, (truncated) Minkowski sum, $x\oplus y=\{ \oplus \mid \in x,\,\, \in y\}$, pointwise ukasiewicz conjunction $x\odot y=\neg(\neg x\oplus \neg y)$, the operators $ x=[\min x,\min x]$, $\nabla x=[\max x,\max x]$,

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.

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

Generation of undular bores in the shelves of slowly-varying solitary waves [PDF]

open access: yes, 2002
We study the long-time evolution of the trailing shelves that form behind solitary waves moving through an inhomogeneous medium, within the framework of the variable-coefficient Korteweg-de Vries equation.
