Physics 2, 43 (2009) – Published May 26, 2009 Statistical Mechanics Interdisciplinary Physics Small nonequilibrium systems behave quite unexpectedly when in contact with a thermal reservoir. However, all of them—from molecular machines to molecular magnets—are described by a single fluctuation theorem. |

Published September 2, 2008 Biological Physics Interdisciplinary Physics Given that vaccine supplies are often limited, a quantitative understanding of how the number and frequency of vaccinations can affect the growth rate of disease would be useful. Physicists show that even a small number of randomly vaccinated individuals can exponentially increase the extinction rate of a disease. |
