Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Genetic admixture in Brazil

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, 2020
AbstractWe review studies from our laboratories using different molecular tools to characterize the Amerindian, European and African ancestry of Brazilians. Initially we used uniparental DNA markers to investigate the contribution of distinct Y chromosome and mitochondrial DNA lineages to present‐day populations.

Genetic admixture in the Late Pleistocene

American Journal of Physical Anthropology, 1996
The replacement hypothesis of modern human origins holds that the original population of modern humans expanded throughout the world, replacing existing archaic populations as it went. If this expanding population interbred with the peoples it replaced, then some archaic mitochondria might have been introduced into the early modern gene pool.

The genetic admixture in Tibetan‐Yi Corridor

American Journal of Physical Anthropology, 2017
AbstractObjectivesThe Tibetan‐Yi Corridor located on the eastern edge of Tibetan Plateau is suggested to be the key region for the origin and diversification of Tibeto‐Burman speaking populations and the main route of the peopling of the Plateau. However, the genetic history of the populations in the Corridor is far from clear due to limited sampling ...

Pharmacogenomics in the Americas: The Impact of Genetic Admixture

Current Drug Targets, 2006
In this review we focus on the impact of genetic admixture on pharmacogenomics in the American continent, where five centuries of intermarriage between Amerindians, European and Africans, resulted in the extensive population heterogeneity observed nowadays.

The Admixture Linkage Disequilibrium and Genetic Linkage Inference on the Gradual Admixture Population

Acta Genetica Sinica, 2006
Through the theoretical analysis of the admixture linkage disequilibrium (ALD) in the gradual admixture (GA) model, in which admixture occurs in every generation, the ALD is found to be proportional to the difference in marker allele frequencies, P1 - P2, between two subpopulations.
