 | Sekercioglu, Cagan | Keystone species in seed dispersal networks are mainly determined by dietary specialization | One central issue in Ecology ecology has been the definition and identification of keystone species, i.e., species that are relatively more important than others for maintaining the structure of a community. Several keystone species concepts have been proposed, and network theory has been pointed o... | 2014-01-01 | |

 | Planelles, Vicente | Kinase control of latent HIV-1 infection: PIM-1 kinase as a major contributor to HIV-1 reactivation | Despite the clinical relevance of latent HIV-1 infection as a block to HIV-1 eradication, the molecular biology of HIV-1 latency remains incompletely understood. We recently demonstrated the presence of a gatekeeper kinase function that controls latent HIV-1 infection. Using kinase array analysis w... | 2014-01-01 | |

 | Khan, Faisal Habib | Magnetic stimulation of mammalian peripheral nerves in vivo: An alternative to functional electrical stimulation | Functional electrical stimulation is the current gold standard for stimulating neuronal interfaces for functional neuromuscular and cortical applications, but it is not without its drawbacks. One such fault is the need to have direct electrical contact with the nerve tissue, and any side effect... | 2014-01-01 | |

 | Tiwari, Ashutosh | Manifestation of two-channel nonlocal spin transport in the shapes of Hanle curves | The dynamics of charge-density fluctuations in a system of two tunnel-coupled wires contains two diffusion modes with dispersion iω = Dq2 and iω = Dq2 + 2τt, where D is the diffusion coefficient and τt is the tunneling time between the wires. The dispersion of corresponding spin-density modes de... | 2014-01-01 | |

 | 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 | |

 | Lupton, John Mark | Mechanisms of spin-dependent dark conductivity in films of a soluble fullerene derivative under bipolar injection | We report room-temperature pulsed electrically detected magnetic resonance measurements of the dark conductivity of films of the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) under bipolar (electron-hole) and unipolar (electron-rich) injection conditions. Directly after mate... | 2014-01-01 | |

 | Balasubramonian, Rajeev | MemZip: exploring unconventional benefits from memory compression | Memory compression has been proposed and deployed in the past to grow the capacity of a memory system and reduce page fault rates. Compression also has secondary benefits: it can reduce energy and bandwidth demands. However, most prior mechanisms have been designed to focus on the capacity metric an... | 2014-01-01 | |

 | Goller, Franz | Motor control of sound frequency in birdsong involves the interaction between air sac pressure and labial tension | Frequency modulation is a salient acoustic feature of birdsong. Its control is usually attributed to the activity of syringeal muscles, which affect the tension of the labia responsible for sound production. We use experimental and theoretical tools to test the hypothesis that for birds producing to... | 2014-01-01 | |
