Lupton, John Mark | Control of mobility in molecular organic semiconductors by dendrimer generation | Conjugated dendrimers are of interest as novel materials for light-emitting diodes. They consist of a luminescent chromophore at the core with highly branched conjugated dendron sidegroups. In these materials, light emission occurs from the core and is independent of generation. The dendron branchin... | Dendrimer generation; Dendron branching; Charge transport; Mobility | 2001-03 |

DeTar, Carleton | f B for various actions: approaching the continuum limit with dynamical fermions | We present results for pseudoscalar decay constants of heavy-light mesons using both quenched and Nf = 2 dynamical fermion configurations. A variety of fermion actions is investigated: Wilson, nonperturbative clover, and fat-link clover. For heavy quarks the Fermilab formalism is applied. In the q... | Decay constants; Wilson fermions | 2001-03 |

Davidson, Diane W. | Herbivory on planted dipterocarp seedlings in secondary logged forests and primary forests of Sabah, Malaysia | Leaf defences, leaf nutritional quality and leaf expansion rates may vary with resource availabilities to plants. Such variation could affect rates of leaf loss to herbivores, particularly along the steep resource gradients in disturbed forests. Intraspecific and interspecific variation in leaf dama... | Danum Valley; Dipterocarp; Dryobalanops lanceolata; Herbivory rates; Leaf damage; Leaf expansion rates; Logged tropical forests; Secondary forests; Shorea leprosula | 2001-03 |

Baehr, Wolfgang; Frederick, Jeanne M.; Church-Kopish, Jill; Howes, Kimberly | Mutant rhodopsin transgene expression on a null background | PURPOSE. To study mechanisms leading to photoreceptor degeneration in mouse models for autosomal dominant retinitis pigmentosa (adRP) based on the rhodopsin P23H mutation. METHODS. Mice of a transgenic line expressing a rhodopsin triple mutant, V20G, P23H, and P27L (GHL), were mated with rhodopsin (... | Mutant Rhodopsin; Photoreceptor Degeneration; Autosomal Dominant Retinitis Pigmentosa; Rhodopsin | 2001-03 |

Wu, Yong-Shi | Remarks on noncommutative open string theory: V duality and holography | In this paper we study the interplay of electric and magnetic backgrounds in determining the decoupling limit of coincident D branes towards a noncommutative Yang-Mills (NCYM) or open string (NCOS) theory. No decoupling limit has been found for the NCYM model with space-time noncommutativity. It i... | Hubbard operator; Bosonization; Deformation; t-J model | 2001-03 |

DeTar, Carleton | Zero temperature string breaking with staggered quarks | The separation of a heavy quark and antiquark pair leads to the formation of a tube of flux, or "string", which should break in the presence of light quark-antiquark pairs. This expected zero-temperature phenomenon has proven elusive in simulations of lattice QCD. In an extension of work reported ... | Flux tube; String breaking; Wilson loop; Staggered quarks | 2001-03 |
