Schmidt, Meic H.; Brockmeyer, Douglas Lee; Dailey, Andrew T. | Surgical management of aneurysmal bone cysts of the spine | Object. Aneurysmal bone cysts of the spine are benign, highly vascular osseous lesions of unknown origin that may present difficult diagnostic and therapeutic challenges. They are expansile lesions containing thin-walled, blood-filled cystic cavities that cause bone destruction and sometimes spinal ... | Aneurysmal bone cyst; Spine tumor; Spinal fusion; Embolization | 2003 |

Scarpulla, Michael | Synthesis of GaNxAs1-x thin films by pulsed laser melting and rapid thermal annealing of N+-implanted GaAs | We present a systematic investigation on the formation of the highly mismatched alloy GaNxAs1-x using N1-implantation followed by a combination of pulsed laser melting and rapid thermal annealing. Thin films of GaNxAs1-x with x as high as 0.016 and an activation efficiency of the implanted N up to 5... | Highly mismatched alloys; Gallium arsenide | 2003 |

Furse, Cynthia M. | Teaching and learning combined (TLC) | Most professors have to lean a LOT. Every day, it seems, there IS something that we need that we don't know. So what do you do to lean this new information? Perhaps you hit the Web or the library, find a tutorial, a textbook, or a paper, and give it a little reading time in between a 12:00 class an... | 2003 | |

Teen childbearing and public policy | About 80 percent of teen pregnancies and 60 percent of all pregnancies in the United States are unintended at conception (Alan Guttmacher Institute, 1999; Henshaw, 1998). When adolescent females give birth, approximately 80 percent are unmarried, compared to 34 percent of women of all ages (Ventu... | Maternity; Adolescence; Minors | 2003 | |

Armentrout, Peter B. | Thermodynamics of ammonia activation by iron cluster cations: guided ion beam studies of the reactions of Fen+ (n=2-10,14) with ND3 | The kinetic energy dependences of the reactions of Fen 1 (n52 - 10,14) with ND3 are studied in a guided ion beam tandem mass spectrometer over the energy range of 0-10 eV. Dehydrogenation of ammonia to form FenND1 is found to be efficient and exothermic for n54 in agreement with previous FT-ICR stu... | 2003 | |

Miller, Jan D. | Thiocarbonate collectors in pyrite flotation ? fundamentals and applications | Recent results from electrochemical measurements demonstrate that trithiocarbonate (TTC) collectors are more readily oxidized to their corresponding dithiolates than the dithiocarbonate/xanthate (DTC) collectors. Based on the traditional analysis of collector adsorption, trithiocarbonates might then... | Trithiocarbonate; xanthate; nitrogen | 2003 |

Ehleringer, James R. | Tracing changes in ecosystem function under elevated carbon dioxide conditions | Responses of ecosystems to elevated levels of atmospheric carbon dioxide (CO2) remain a critical uncertainty in global change research. Two key unknown factors are the fate of carbon newly incorporated by photosynthesis into various pools within the ecosystem and the extent to which elevated CO2 is... | Elevated carbon dioxide; Stable isotopes; Radiocarbon; Global change; Terrestrial ecosystems | 2003 |

Kestle, John R. W. | Tracking resident work hours: available software is not yet ideal, but it's helpful | An ideal system would be completely passive and would allow more detailed tracking of activity inside the hospital. A new reality began July 1. We are all now responsible for tracking our residents' work hours and ensuring compliance with the new regulations mandated by the Accreditation Council fo... | Resident work hours; Tracking; TimeClock system | 2003 |

Martin, Jim; Pardyjak, Eric R. | Training with power measurement: a new era in cycling training | PROVIDING CYCLISTS WITH A reliable measure of exercise intensity presents unique challenges. Environmental factors such as wind speed, road grade and surface texture, and air density interactively influence the resistance encountered during cycling and thus alter the speed a cyclist can maintain wh... | Exercise; Intensity; Heart rate | 2003 |

Schmidt, Meic H.; Kestle, John R. W. | Treatment of metastatic spinal epidural disease: a review of the literature | Object. Spinal cord compression is one of the most dreaded complications of metastatic cancer. It can lead to a number of sequelae, including pain, spinal instability, neurological deficits, and a reduction in the patient's quality of life. Except in selected circumstances, treatment is palliative. ... | Spinal cord compression; Metastasis; Radiation therapy; Stereotactic radiosurgery | 2003 |

Coley, Phyllis D.; Kursar, Thomas A. | Using ecological criteria to design plant collection strategies for drug discovery | Tropical forests are one of the most diverse and endangered habitats on earth. They have also been portrayed as a source of future pharmaceuticals, yet finding useful compounds can be both scientifically and politically challenging. Increasingly, over the past decade, the potential value of medicina... | Drug discovery; Biodiversity | 2003 |

Myers, Chris J. | Verification of timed circuits with failure directed abstractions | This paper presents a method to address state explosion in timed circuit verification by using abstraction directed by the failure model. This method allows us to decompose the verification problem into a set of subproblems, each of which proves that a specific failure condition does not occur. To... | 2003 | |

Hansen, Charles D. | Visually accurate multi-field weather visualization | Weather visualization is a difficult problem because it comprises volumetric multi-field data and traditional surface-based approaches obscure details of the complex three-dimensional structure of cloud dynamics. Therefore, visually accurate volumetric multi-field visualization of storm scale and cl... | Weather visualization; Multifield visualization; Volume rendering | 2003 |

Goller, Franz | White-crowned sparrows tutored with syllable pairs can produce full songs | During their 'sensitive period', young songbirds develop an 'acquired template', representing a memory of the song(s) that it hears. Later, during the sensorimotor phase, birds use this template to evaluate, via auditory feedback, their vocalizations. | Acquired template; Sensorimotor period; Temporal isolation | 2003 |

Sperry, John S. | Xylem hydraulics and the soil-plant-atmosphere continuum: opportunities and unresolved issues | Received for publication July 23, 2002. Soil and xylem are similar hydraulically. An unsaturated conductivity curve for soil is called a vulnerability curve for xylem?but the underlying physical basis is the same. Thus, any transport model that treats unsaturated soil conductivity would benefit by a... | Soil?plant?atmosphere continuum; Water potential | 2003 |

Couldwell, William T. | Zones of approach for craniofacial resection: minimizing facial incisions for resection of anterior cranial base and paranasal sinus tumors | Anterior cranial base tumors are surgically resected with combined craniofacial approaches that frequently involve disfiguring facial incisions and facial osteotomies. The authors outline three operative zones of the anterior cranial base and paranasal sinuses in which tumors can be resected with th... | Anatomic study; Anterior cranial base; Cranial base surgery; Craniofacial surgery; Minimally invasive | 2003 |

Olivera, Baldomero M.; McIntosh, J. Michael | α-Conotoxins ImI and ImII: similar α7 nicotinic receptor antagonists act at different sites | A novel conotoxin, α-conotoxin ImII (α-CTx ImII), identified from Conus imperialis venom ducts, was chemically synthesized. A previously characterized C. imperialis conotoxin, α-conotoxin ImI (α-CTx ImI), is closely related; 9 of 12 amino acids are identical. Both α-CTx ImII and α-CTx ImI... | Conotoxins; Conotoxin ImI; Conotoxin ImII | 2003 |
