On the relative abundance of LiH and LiH+ molecules in the early universe: new results from quantum reactions

open access: yes, 2011
The relative efficiencies of the chemical pathways that can lead to the destruction of LiH and LiH+ molecules, conjectured to be present in the primordial gas and to control molecular cooling processes in the gravitational collapse of the post ...

Genotype‐By‐Environment Interaction for Scrotal Circumference in Young Nellore Bulls Under Pasture and Feedlot Conditions and Its Correlation With Days to Calving

open access: yesAnimal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT Scrotal circumference (SC) is a key reproductive indicator in beef cattle and an important predictor of male puberty and correlated female fertility. In this study, we evaluated young Nellore bulls raised under combinations of pasture and feedlot environments and modeled SC using a “double” reaction norm model. Additive genetic variance for SC

Chemical complexity in astrophysical simulations: optimization and reduction techniques

open access: yes, 2013
Chemistry has a key role in the evolution of the interstellar medium (ISM), so it is highly desirable to follow its evolution in numerical simulations. However, it may easily dominate the computational cost when applied to large systems. In this paper we

Genomic Prediction and Genome‐Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 342-353, March 2026.
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.
