Vardeny, Zeev Valentine | The effects of charge injection in single-wall carbon nanotubes studied by charge-induced absorption | We studied direct charge injection in a heterogeneous film of single-wall carbon nanotubes using the technique of charge-induced absorption. We found that the injected charges screen the excitons in the semiconducting tubes, reducing their binding energy and transferring oscillator strength from the... | | 2011 |

Dawson, Kyle | The effects of charge transfer inefficiency (CTI) on galaxy shape measurements | We examine the effects of charge transfer inefficiency (CTI) during CCD readout on the demanding galaxy shape measurements required by studies of weak gravitational lensing.

Sekercioglu, Cagan | The effects of climate change on tropical birds | Birds are among the most widely studied organisms on earth and represent an important indicator group for learning about the effects of climate change - particularly in regard to the effects of climate change on tropical ecosystems. In this review, we assess the potential impacts of climate change o... | | 2010-01-01 |

Hughes, Kelly T. | The effects of codon context on in vivo translation speed | We developed a bacterial genetic system based on translation of the his operon leader peptide gene to determine the relative speed at which the ribosome reads single or multiple codons in vivo. Low frequency effects of so-called ‘‘silent'' codon changes and codon neighbor (context) effects could... | | 2014-01-01 |

Adler, Frederick R. | Effects of intraspecific density-dependence on species richness and species abundance distributions | Abstract Species richness and patterns of abundance result from the interplay between niche differences, realized as intraspecific density-dependence (IDD), and so-called neutral processes that arise when species fitnesses are similar. This paper presents an extension of neutral models that incorpo... | | 2010 |

Mattis, Daniel C. | Effects of orbital degeneracy on a magnetic impurity in a nonmagnetic metal | We study the Green's-function equations for a version of the two-orbital Anderson model of a magnetic impurity, in an approximation scheme that displays the logarithmic anomalies and enables the Kondo temperature Tĸ to be calculated as a function of the parameters. The nature of the solutions is ex... | Orbital degeneracy; Magnetic impurities; Nonmagnetic metal; Kondo temperature; Anomalous resonances | 1969-02 |

Gondolo, Paolo | Effects of the Sagittarius dwarf tidal stream on dark matter detectors | The Sagittarius dwarf tidal stream may be showering dark matter onto the solar neighborhood, which can change the results and interpretation of direct detection searches for weakly interacting massive particles (WIMPs).

Coley, Phyllis D.; Kursar, Thomas A. | Effects of weather on fungal abundance and richness among 25 communities in the Intermountain West | Because moisture and temperature influence the growth of fungi, characterizing weather conditions favorable for fungi may be used to predict the abundance and richness of fungi in habitats with different climate conditions. To estimate habitat favorability to fungi, we examined the relationship of f... | Intermountain West; Utah; Microclimate; Fungal prevalence | 2002 |

Vardeny, Zeev Valentine | Efficiency enhancement of an organic light-emitting diode with a cathode forming two-dimensional periodic hole array | We fabricated an organic light-emitting diode using a ∏-conjugated polymer emissive layer sandwiched between two semitransparent electrodes: an optically thin gold film anode, whereas the cathode was in the form of an optically thick aluminum (Al) film with patterned periodic subwavelength two-dim... | pi-conjugated polymers; Organic light-emitting diode; OLED | 2005 |

Thomas, Kirk R.; Capecchi, Mario R. | Efficient correction of mismatched bases in plasmid heteroduplexes injected into cultured mammalian cell nuclei. | Heteroduplexes were prepared from two plasmids, pRH4-14/TK and pRH5-8/TK, containing different amber mutations in the neomycin resistance gene (Neor). The Neor gene was engineered to be expressed in both bacterial and mammalian cells. A functional Neor gene conferred kanamycin resistance to bacteria... | Cell Nucleus; Cells, Cultured; Microinjections | 1985-01 |

Gesteland, Raymond F.; Weiss, Robert B. | Efficient shine- Dalgarno sequence but not translation is necessary for LacZ mRNA stability in Escherichia coli | The 5' ends of many bacterial transcripts are important in determining mRNA stability. A series of Shine-Dalgarno (SD) sequence changes showed that the complementarity of the SD sequence to the anti-SD sequence of 16S rRNA correlates with lacZ mRNA stability in Escherichia coli. Several initiation c... | Protein Biosynthesis; Ribosomes; Escherichia coli; Shine-Dalgarno Sequence | 1994 |

Bohs, Lynn A. | Eggplant origins: out of Africa, into the Orient | The eggplant (Solanum melongena L.), also known as aubergine or brinjal, has been cultivated for centuries in the Old World and is currently a crop species of global importance. Despite this, hypotheses of eggplant evolution have been fraught with controversy. Previous conclusions have relied solely... | Eggplant origins; Crop domestication; Solanum melongena complex; Solanum incanum; DNA sequence; Africa; Asia | 2010 |

Mattis, Daniel C. | Eigenfunction localization in dilute lattices of various dimensionalities | As a fraction of bonds p is removed from a lattice, we find a threshold PQ above which all eigenstates are nonpropagating (Anderson localized). This occurs well before the classical percolation threshold. For example, in two dimensions where the classical threshold is pc = 1/2 , we find PQ = 0. | Eigenstates; Dilute lattices | 1981-05 |

Bromley, Benjamin C. | Eigenspectral computtations for linear gravity and nonlinear toy models | The periodic standing-wave approach to binary inspiral assumes rigid rotation of gravitational fields and hence helically symmetric solutions. To exploit the symmetry, numerical computations must solve for "helical scalars," fields that are functions only of corotating coordinates, the labels on the... | Binary black holes; General relativity; Standing wave | 2006 |

Mattis, Daniel C. | Eigenstates of N excitons and one hole | We solve for the eigenstates and energy eigenvalues of N immobile Frenkel excitons (a relatively trivial proposition) and of N such excitons plus one hole (which for large N can only be done in one dimension). We also guess that a charged globule, consisting of N excitons and O(N) holes, can be stab... | Eigenstates; Frenkel excitons; Many-body problem | 1983-04 |
