Spectral Transforms as a Tool to Optimize Digital Phenotyping in Biological Images
Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Modern livestock breeding has mastered genotyping. Genome‐wide association studies, genomic selection, and SNP arrays enable genetic merit prediction at lower cost. However, phenotyping remains the bottleneck, as manual measurement is slow, expensive, subjective, and unable to capture spatial or temporal trait organization. Digital phenotyping

Amino acid racemization dating: Method development using African ostrich (Struthio camelus) eggshell [PDF]
, 2013 Ostrich eggshell (OES) is ubiquitous in archaeological sites in Africa and is a favoured substrate for amino acid racemisation (AAR) geochronology, yielding consistent results and thought to approximate a closed system with respect to protein diagenesis.
