Efficiency of the Dynamical Mechanism [PDF]

open access: yes, 2005
The most extreme starbursts occur in galaxy mergers, and it is now acknowledged that dynamical triggering has a primary importance in star formation. This triggering is due partly to the enhanced velocity dispersion provided by gravitational instabilities, such as density waves and bars, but mainly to the radial gas flows they drive, allowing large ...

Efficiencies and Mechanisms of Nuclear Reprogramming [PDF]

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 2010
The differentiated state of somatic cells is highly stable, but it can be experimentally reversed. The resulting cells can then be redirected into many different pathways. Nuclear reprogramming has been achieved by nuclear transfer to eggs, cell fusion, and overexpression of transcription factors.

Efficiency, Equity, and Timing of Voting Mechanisms [PDF]

open access: yesAmerican Political Science Review, 2007
We compare the behavior of voters under simultaneous and sequential voting rules when voting is costly and information is incomplete. In many political institutions, ranging from small committees to mass elections, voting is sequential, which allows some voters to know the choices of earlier voters.
