Fife, Paul C.; McMurtry, Patrick | Properties of the mean momentum balance in turbulent boundary layer, pipe and channel flows | The properties of the mean momentum balance in turbulent boundary layer, pipe and channel flows are explored both experimentally and theoretically. Available high-quality data reveal a dynamically relevant four-layer description that is a departure from the mean profile four-layer description tradit... | Turbulent channel flow; Pipe flow; Reynolds stress | 2005 |

Boehme, Christoph; Friedrich, Frances | Pulsed EDMR study of charge trapping at Pb centers | Low temperature pulsed electrically detected magnetic resonance (pEDMR) measurements of charge trapping and recombination transitions involving Pb centers at the c-Si (111) /Si02 interface are presented. The results of these experiments show that when a conduction electron is trapped, it forms a str... | Charge trapping; Lande factor | 2005 |

Adler, Frederick R. | Recent rapid increases in the right whale (Eubalaena australis) population off southern Brazil | Right whales (Eubalaena australis) that gather on a wintering ground off southern Brazil have been aerial surveyed and photographically identified since 1987. As of 2003 the Brazilian Right Whale Catalogue has 315 different individual whales of which 31 were resighted in other years (23 females, 3 y... | 2005 | |

Potts, Wayne K. | Relationship of virulence factor expression to evolved virulence in mouse-passaged Cryptococcus neoformans lines | Serial passage of Cryptococcus neoformans in mice increases virulence relative to the nonpassaged line. Postpassaged lines showed no difference in the expression of most known virulence factors, with the exception that the more virulent lines had smaller capsules in vitro. These data imply that othe... | Capsule; Death; Passage | 2005 |

Williams, Clayton C. | Single-electron manipulation to and from a SiO2 surface by electrostatic force microscopy | Occupation of individual electron states near the surface of a SiO2 film is controlled by reversible single-electron tunneling to or from a metallic electrostatic force microscope probe. By switching the polarity of an applied dc bias between the probe and the sample to adjust the Fermi energy of ... | 2005 | |

Bohs, Lynn A. | Solanaceae: the potato family | Shrubs, herbs, woody vines, occasionally trees, glabrous or pubescent with simple, glandular, branched, or star-shaped hairs, sometimes with prickles. Lvs alternate or paired but not truly opposite, simple or lobed to pinnately compound; stipules absent. Infl composed of variously modified terminal... | Browallia; Brugmansia; Brunfelsia; Capsicum; Cestrum; Petunia; Physalis; Solandra; Solanum; Streptosolen | 2005 |

Vardeny, Zeev Valentine | Spin and magnetic field effects in organic semiconductor devices | The authors describe three spin and magnetic field effects in organic semiconductor devices: First, injection, transport and detection of spin-polarised carriers using an organic semiconductor as the spacer layer in a spin-valve structure, yielding low-temperature giant magnetoresistance effects as... | Spin effects; Magnetic field effects; MR; OLED; Organic light-emitting diode; Spin-polarised carriers; Spin-dependent exciton formation; Electroluminescent efficiency; pi-conjugated organic semicondutors; OSEC | 2005 |

Fife, Paul C.; McMurtry, Patrick | Stress gradient balance layers and scale hierarchies in wall-bounded turbulent flows | Steady Couette and pressure-driven turbulent channel flows have large regions in which the gradients of the viscous and Reynolds stresses are approximately in balance (stress gradient balance regions). In the case of Couette flow, this region occupies the entire channel. Moreover, the relevant featu... | Couette flow; Stress gradient balance; Reynolds stress; Turbulent channel flow | 2005 |

Goller, Franz | Synthesizing bird song | In this work we present an electronic syrinx: an analogical integrator of the equations describing a model for sound production by oscine birds. The model depends on time varying parameters with clear biological interpretation: the air sac pressure and the tension of ventral syringeal muscles. We te... | Syrinx; Tension; Transducer | 2005 |

Vardeny, Zeev Valentine | Transport studies of isolated molecular wires in self-assembled monolayer devices | We have fabricated a variety of isolated molecule diodes based on self-assembled monolayers (SAM) of solid-state mixture (SSM) of molecular wires [1,4-methane benzene dithiol (Me-BDT)], and molecular insulator spacers [penthane 1-thiol (PT)] with different concentration ratios r of wires/spacers, wh... | Transport studies; Molecular wires; Monolayer devices | 2005 |

Boehme, Christoph | Triplet recombination at Pb centers and its implications for capture cross sections | Pulsed electrically detected magnetic resonance measurements are presented showing that Pb centers at the crystalline silicon (c-Sid) (111) to silicon dioxide sSiO2d interface can cause recombination of strongly coupled spin pairs in singlet and triplet configurations. The implication of these find... | Silicon interfaces | 2005 |

Vardeny, Zeev Valentine | Ultrafast spectroscopy of excitons in semiconducting carbon nanotubes | Ultrafast relaxation dynamics of photoexcitations in semiconducting single walled carbon nanotubes (S-NTs) were investigated using polarized pump-probe photomodulation (with 150 fs time resolution) and cw polarized photoluminescence (PL). Both annealed and unannealed NT films and D 2 0 solutions of ... | Non-linear optical methods; Carbon nanotubes; ultrafast dynamics | 2005 |

Adler, Frederick R.; Liou, Theodore G. | Use of lung transplantation survival models to refine patient selection in cystic fibrosis | Lung transplantation in cystic fibrosis may improve survival for patients with low 5-year predicted survival. Identifying characteristics that affect post-transplantation survival may improve patient selection and survival benefit. Using Cystic Fibrosis Foundation Patient Registry and United Network... | Lung transplation; Survival; Burkholderia cepacia | 2005 |

Adler, Frederick R.; Jackson, Brian Richard; Carroll, Karen C.; Samore, Matthew H. | Use of strain typing data to estimate bacterial transmission rates in healthcare settings | OBJECTIVE: To create an affordable and accurate method for continuously monitoring bacterial transmission rates in healthcare settings. DESIGN: We present a discrete simulation model that relies on the relationship between in-hospital transmission rates and strain diversity. We also present a proof... | Strain typing; Infection control; Transmission model | 2005 |
