 | Clayton, Dale H. | An experimental test of the effects of behavioral and immunological defenses against vectors: do they interact to protect birds from blood parasites? | Background: Blood-feeding arthropods can harm their hosts in many ways, such as through direct tissue damage and anemia, but also by distracting hosts from foraging or watching for predators. Blood-borne pathogens transmitted by arthropods can further harm the host. Thus, effective behavioral and im... | | 2014-01-01 |

 | Parkinson, John Stansfield | An unorthodox sensory adaptation site in the E. coli serine chemoreceptor | The serine chemoreceptor of E. coli contains four canonical methylation sites for sensory adaptation that lie near inter-subunit helix interfaces of the Tsr homodimer. An unexplored fifth methylation site, E502, lies at an intra-subunit helix interface, closest to the HAMP domain that controls input... | | 2014-01-01 |

 | Mishchenko, Eugene | Attraction-repulsion transition in the interaction of adatoms and vacancies in graphene | The interaction of two resonant impurities in graphene has been predicted to have a long-range character with weaker repulsion when the two adatoms reside on the same sublattice and stronger attraction when they are on different sublattices. We reveal that this attraction results from a single energ... | | 2014-01-01 |

 | Gondolo, Paolo | Axion cold dark matter in view of BICEP2 results | The properties of axions that constitute 100% of cold dark matter (CDM) depend on the tensor-to-scalar ratio r at the end of inflation. If r ¼ 0.20 þ0.07 −0.05 as reported by the BICEP2 Collaboration, then "half" of the CDM axion parameter space is ruled out. Namely, in the context of single-fie... | | 2014-01-01 |

 | Jorgensen, Erik | Axon regeneration genes identified by RNAi screening in C. elegans | Axons of the mammalian CNS lose the ability to regenerate soon after development due to both an inhibitory CNS environment and the loss of cell-intrinsic factors necessary for regeneration. The complex molecular events required for robust regeneration of mature neurons are not fully understood, part... | | 2014-01-01 |

 | Hughes, Kelly T. | Bacterial flagellin-specific chaperone FliS interacts with anti-sigma factor FlgM | Flagella are extracellular organelles that propel bacteria. Each flagellum consists of a basal body, a hook, and a filament. The major protein of the filament is flagellin. To prevent premature polymerization of newly synthesized flagellin molecules, FliS, the flagellin-specific chaperone, binds fla... | | 2014-01-01 |

 | Minteer, Shelley D. | Characterizing efficiency of multi-Enzyme cascade-based biofuel cells by product analysis | The performance of biofuel cells with enzyme cascades have normally been characterized with open circuit potential, power density, and current density measurements.

 | Coley, Phyllis D. | Chemical and bioactive natural products from microthyriaceae sp., an endophytic fungus from a tropical grass | In screening for natural products with antiparasitic activity, an endophytic fungus, strain F2611, isolated from above-ground tissue of the tropical grass Paspalum conjugatum (Poaceae) in Panama, was chosen for bioactive principle elucidation. Cultivation on malt extract agar (MEA) followed by bioas... | | 2014-01-01 |

 | Olivera, Baldomero M. | Combined proteomic and transcriptomic interrogation of the venom gland of conus geographus uncovers novel components and functional compartmentalization | Cone snails are highly successful marine predators that use complex venoms to capture prey. At any given time, hundreds of toxins (conotoxins) are synthesized in the secretory epithelial cells of the venom gland, a long and convoluted organ that can measure 4 times the length of the snail's body. In... | | 2014-01-01 |

 | Saam, Brian | Comment on: New limit on lorentz-invariance- and CPT-violating neutron spin interactions using a free-spin-precession 3He- 129Xe comagnetometer | In Ref. [1], the authors use a classical result for the magnetic field created by a uniform magnetization to analyze the effects of magnetic interactions between 3He and 129Xe nuclear spins. We point out that the classical result is not applicable for interaction between nuclear spins: the actual in... | | 2014-01-01 |

The 2Ih free base enantiomers were synthesized from 2'-deoxyguanosine oxidized with a Cu(II)/H2O2 oxidant system followed by hydrolysis of the N-glycosidic bond.

 | Minteer, Shelley D. | Controlled placement of enzymes on carbon nanotubes using comb-branched DNA | Immobilization is not only useful for preserving enzyme activity, but also to adhere an enzyme to a surface, such as an electrode, so that the enzyme does not leach into solution during testing. Current immobilization approaches do not readily allow for adjustments to the distance between the enzyme... | | 2014-01-01 |

 | Bowling, David R. | Ecological processes dominate the 13C land disequilibrium in a Rocky Mountain subalpine forest | Fossil fuel combustion has increased atmospheric CO2 by ≈ 115 μmol mol1 since 1750 and decreased its carbon isotope composition (δ13C) by 1.7-2‰(the 13C Suess effect). Because carbon is stored in the terrestrial biosphere for decades and longer, the δ13C of CO2 released by terrestrial ecosyst... | | 2014-01-01 |

 | Mishchenko, Eugene | Equilibrium currents in chiral systems with nonzero Chern number | We describe a simple quantum-mechanical approach to calculating equilibrium particle current along the edge of a system with nontrivial band spectrum topology. The approach does not require any a priori knowledge of the band topology and, as a matter of fact, treats topological and nontopological co... | | 2014-01-01 |
