Beckerle, Mary C. | Mathematical modeling of the dynamic mechanical behavior of neighboring sarcomeres in actin stress fibers | Actin stress fibers (SFs) in live cells consist of series of dynamic individual sarcomeric units. Within a group of consecutive SF sarcomeres, individual sarcomeres can spontaneously shorten or lengthen without changing the overall length of this group, but the underlying mechanism is unclear. We us... | 2014-01-01 | |

Gondolo, Paolo | The effect of quark interactions on dark matter kinetic decoupling and the mass of the smallest dark halos | The kinetic decoupling of dark matter (DM) from the primordial plasma sets the size of the first and smallest DM halos. Studies of the DM kinetic decoupling have hitherto mostly neglected interactions between the DM and the quarks in the plasma. Here we illustrate their importance using two framewor... | 2012-01-01 | |

Clayton, Dale H. | How effective is preening against mobile ectoparasites? An experimental test with pigeons and hippoboscid flies | Birds combat ectoparasites with many defences but the first line of defence is grooming behaviour, which includes preening with the bill and scratching with the feet. Preening has been shown to be very effective against ectoparasites. However, most tests have been with feather lice, which are relati... | 2012-01-01 | |
