Admixture in Latin America: geographic structure, phenotypic diversity and self-perception of ancestry based on 7,342 individuals. [PDF]
PLoS Genetics, 2014 The current genetic makeup of Latin America has been shaped by a history of extensive admixture between Africans, Europeans and Native Americans, a process taking place within the context of extensive geographic and social stratification.

Ancestry-Dependent Enrichment of Deleterious Homozygotes in Runs of Homozygosity. [PDF]
, 2019 Runs of homozygosity (ROH) are important genomic features that manifest when an individual inherits two haplotypes that are identical by descent. Their length distributions are informative about population history, and their genomic locations are useful ...

What Do Large Language Models Know About Materials?
Advanced Engineering Materials, EarlyView.If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Advanced Engineering Materials, EarlyView.This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

, 2022 Les métissages génétiques sont un mécanisme essentiel de l'évolution biologique de nombreuses espèces, dont Homo sapiens. Dans cette Habilitation à Diriger des Recherches, nous étudions les Histoires de Métissages dans les populations humaines, de la théorie de la génétique des populations à l'analyse de données, en passant par l'échantillonnage ...

The genomic footprints of migration: how ancient DNA reveals our history of mobility
Genome BiologyAncient DNA has emerged as a powerful tool for studying human migration through the detection of admixture signatures. Here, we present the theoretical principles and methodologies for admixture analysis, with an emphasis on f-statistics and qpAdm.

Advanced Engineering Materials, EarlyView.This article demonstrates the successful qualification of a copper–tungsten composite for laser powder bed fusion. The resulting components exhibited high density, high thermal conductivity, and reduced thermal expansion. Heat sinks with complex geometries were successfully manufactured, clearly showcasing the material's potential for additive ...

EPAS1 variants in high altitude Tibetan wolves were selectively introgressed into highland dogs [PDF]
PeerJ, 2017 Background Admixture can facilitate adaptation. For example, black wolves have obtained the variant causing black coat color through past hybridization with domestic dogs and have higher fitness than gray colored wolves.
