Effect of High-Shear Mixing on Alignment of Carbon Nanofiber/Epoxy Nanocomposites
Abstract: AbstractOne of the major technological issues limiting widespread use of epoxy polymer nanocomposites containing carbon nanofibers is processability, where the dispersion or alignment of the nanofibers is crucial to performance of the composite. Poor dispersion of the nanofibers can lead to deterioration in properties, while aligning them affords the opportunity to maximize properties in a given direction. The authors have recently investigated the effect of high-shear mixing as a potential …

Comparative Evaluation of Pedigree-Based and Genomic BLUP Models for Wheat Grain Yield Prediction
Abstract: Before genome-wide molecular markers became affordable, plant and animal breeding relied on pedigree-based prediction (P-BLUP), using the expected additive relationship matrix (A) derived from recorded ancestry. Genomic selection replaced or augmented this with a marker-derived genomic relationship matrix (G; GBLUP), and single-step methods combining A and G are now standard when only a subset of a breeding population is genotyped. It is less clear whether pedigree information retains any predictive …
