Abstract Disease-causing variants have been identified for less than 20% of suspected equine genetic diseases. Whole genome sequencing (WGS) allows rapid identification of rare disease causal variants. However, interpreting the clinical variant conse

Genetic variation is a key contributor to health and disease. Understanding the link between an individual’s genotype and the corresponding phenotype is a major goal of medical genetics. Whole genome sequencing (WGS) within and across populations e

An experimental study of microstructures in a directionally solidified, near-eutectic Ag-Cu-Sn alloy has been completed. This material is an important candidate for use as a lead-free solder, and the studies show the origin and velocity dependence of

The tin–silver–copper eutectic is a three-phase eutectic consisting of Ag3Sn plates and Cu6Sn5rods in a (Sn) matrix. It was thought that the two phases would coarsen independently. Directionally solidified ternary eutectic and binary eutectic sam

A set of nickel-based superalloy single-crystal investment castings was evaluated for crystal perfection. Defect structures near the seed emergence point and other geometric features were examined using X-ray topography. Topographic images were compa

If shear stresses are present during isostatic pressing of a powder compact they may distort its shape, enhance densification, or both. A flow surface is required to predict these effects, but those available have been developed for highly consolidat

A study has been made of the morphology of directionally solidified CuAl-Pb monotectic alloys. The structure consisted of a hexagonal array of Pb rods in a Cu-based matrix. In addition, highly curved grain boundaries in the Cu-based matrix with lens-

A study was recently undertaken to consolidate Sm2Fe17N3−x‐based materials by hot isostatic pressing (HIPing). For HIPing, pressed green samples were placed at the center of evacuated, closely fitting, nonmagnetic, thin‐walled, stainless‐stee
