The evolution of sperm morphometry in pheasants [PDF]

, 2007
Postcopulatory sexual selection is thought to be a potent evolutionary force driving the diversification of sperm shape and function across species. In birds, insemination and fertilisation are separated in time and sperm storage increases the duration

US Competitiveness in Synthetic Biology [PDF]

Health Security, 2015
Synthetic biology is an emerging technical field that aims to make biology easier to engineer; the field has applications in strategically important sectors for the US economy. While the United States currently leads in synthetic biology R&D, other nations are heavily investing in order to boost their economies, which will inevitably diminish the US ...

Stem cell lineage survival as a noisy competition for niche access [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance What defines the number and dynamics of the stem cells that generate and renew biological tissues? Although several molecular markers have been described to predict stem cell potential, we propose a complementary approach that mathematically

Modeling viral coevolution: HIV multi-clonal persistence and competition dynamics [PDF]

, 2005
The coexistence of different viral strains (quasispecies) within the same host are nowadays observed for a growing number of viruses, most notably HIV, Marburg and Ebola, but the conditions for the formation and survival of new strains have not yet been ...

Synthesizing a novel genetic sequential logic circuit: a push‐on push‐off switch

Molecular Systems Biology, 2010
Design and synthesis of basic functional circuits are the fundamental tasks of synthetic biologists. Before it is possible to engineer higher‐order genetic networks that can perform complex functions, a toolkit of basic devices must be developed.

Change and Aging Senescence as an adaptation [PDF]

, 2011
Understanding why we age is a long-lived open problem in evolutionary biology. Aging is prejudicial to the individual and evolutionary forces should prevent it, but many species show signs of senescence as individuals age.

Principles of parametric estimation in modeling language competition [PDF]

, 2013
It is generally difficult to define reasonable parameters and interpret their values in mathematical models of social phenomena. Rather than directly fitting abstract parameters against empirical data, we should define some concrete parameters to denote ...
