52 Drews, Frank; Westenskow, Dwayne R.; Bermudez, Julio Cesar; Syroid, Noah Daniel; Agutter, James A.; Strayer, David LeeEvaluation of a cardiovascular display in a high fidelity simulatorHuman error in anesthesia can be attributed to misleading information from patient monitors or to the physician's failure to recognize a pattern. A graphic representation of monitored data may provide better support for detection, diagnosis, and treatment. We designed a graphic display to show hemod...Patient monitors; Visual information; Graphic displays2003
53 Sperry, John S.Evolution of water transport and xylem structureLand plants need water to replace the evaporation that occurs while atmospheric CO2 is diffusing into photosynthetic tissue. The water-for-carbon exchange rate is poor, and evolutionary history indicates a progression of innovations for cheap water transport--beginning in order with capillary sucti...Cavitation; Vessels; Plants2003
54 Vardeny, Zeev ValentineExcitons, polarons, and laser action in poly(p-phenylene vinylene) filmsWe have used a multitude of linear and nonlinear cw optical spectroscopies to study the optical properties of water precursor poly(p-phenylene vinylene) (PPV) thin films. These spectroscopies include absorption, photoluminescence, photoinduced absorption and their respective optically detected magne...PPV films; Excitons; Laser action; Poly(p-phenylene vinylene)2003
55 Ehleringer, James R.; Cerling, Thure E.; Dearing, Maria-DeniseExperimental study of carbon-isotope fractionation between diet, hair, and feces of mammalian herbivoresThe carbon-isotope composition of hair and feces offers a glimpse into the diets of mammalian herbivores. It is particularly useful for determining the relative consumption of browse and graze in tropical environments, as these foods have strongly divergent carbon-isotope compositions. Fecal ?13C v...Fractionation; Mammalian herbivores; Medicago sativa; Cynodon dactylon2003
56 Goller, FranzExperimental support for a model of birdsong productionIn this work we present an experimental validation of a recently proposed model for the production of birdsongs. We have previously observed that driving the model with simple functions of time, which represent tensions in vocal muscles, produces a wide variety of sounds resembling birdsongs. In th...Vocal; Muscles; Syrinx2003
57 Clayton, Dale H.Experimental test of the importance of preen oil in Rock Doves (Columba livia)Most species of birds have a uropygial gland, also known as a preen gland, which produces oil that birds spread through their plumage when preening. The plumage of waterfowl deprived of uropygial oil becomes brittle and is subject to breakage.Columba livia; Columbiformes; Preen oil; Ectoparasites; Columbicola columbae; Campanulotes compare; Plumage2003
58 Zimmer, ZacharyFamily size and support of older adults in urban and rural China: current effects and future implicationsChina will experience rapid growth in the proportion and number of older people in its population in the near future as a consequence of an extraordinarily rapid decline in fertility over the past several decades. Total fertility rates were as high as 7.5 in the early 1950s, but have fallen to below...Urban China; Rural China; Support; Older adults; One-child policy2003
59 Lindstrom, Gary E.Fast and accurate NN approach for multi-event annotation of time seriesSimilarity search in time-series subsequences is an important time series data mining task. Searching in time series subsequences for matches for a set of shapes is an extension of this task and is equally important. In this work we propose a simple but efficient approach for finding matches for a g...Time-series subsequences; Nearest neighbor approach; Multi-event2003
60 Eddings, Eric G.; Sarofim, Adel F.Fast cook-off tests reportThe Center for the Simulation of Accidental Fires and Explosions (C-SAFE) at the University of Utah is focused on providing science-based tools for the numerical simulation of accident scenarios involving fires and high-energy devices (Pershing, 2000). The initial computational efforts are concentra...Heat flux; Heat transfer; Cookoff tests; Center for the Simulation of Accidental Fires and Explosions; C-SAFE2003
61 Tasdizen, Tolga; Whitaker, Ross T.Feature preserving variational smoothing of terrain dataIn this paper, we present a novel two-step, variational and feature preserving smoothing method for terrain data. The first step computes the field of 3D normal vectors from the height map and smoothes them by minimizing a robust penalty function of curvature. This penalty function favors piecewise ...2003
62 Mallat, ChibliFederalism in the Middle East and EuropeFederalism is well know in its first, well-established dimension thanks to the extraordinary tradition this country has known. It is less known and is currently a big battle in process in Europe. It is completely unkown and is, I think, the intellectual battle to come in the Middle East. So, these w...2003
63 Scarpulla, MichaelFerromagnetic Ga1-xMnxAs produced by ion implantation and pulsed-laser meltingWe demonstrate the formation of ferromagnetic Ga1-xMnxAs films by Mn ion implantation into GaAs followed by pulsed-laser melting. Irradiation with a single excimer laser pulse results in the epitaxial regrowth of the implanted layer with Mn substitutional fraction up to 80% and effective Curie tempe...Gallium arsenide; Ferromagnetic semiconductors; Remanent magnetization2003
64 Waitzman, Norman J.For cost-reducing technologies, knowing markets is to change themSponsored research from a NSF Foundation/Whitaker Foundation initiative on cost-reducing technologies brought together faculty from engineering, medicine, and social sciences to link economic and policy assessments to engineering design.

66 Kraus, Peter L.Francis Carroll, Good and wise measure: the search for the Canadian-American boundary, 1783-1842A Good and Wise Measure is not only a groundbreaking historical work; it is also a delight to those who work in the area of cartography, maps, or government documents in libraries. The author makes extensive use of original source material and numerous obscure resources. Simply put, this book can se...2003
67 Hansen, Charles D.Gaussian transfer functions for multi-field volume visualizationVolume rendering is a flexible technique for visualizing dense 3D volumetric datasets. A central element of volume rendering is the conversion between data values and observable quantities such as color and opacity. This process is usually realized through the use of transfer functions that are prec...Volume rendering; Transfer functions; Volume visualization2003
68 Tiwari, AshutoshGrowth and characterization of TaN/TiN superlattice structuresEpitaxial B1 NaCl-structured TaN(3 nm)/TiN(2 nm) superlattice structures were grown on Si(100) substrates with a TiN buffer layer, using pulsed-laser deposition.

73 Zimmer, ZacharyHow indicators of socioeconomic status relate to physical functioning of older adults in three Asian societiesIn developed countries, socioeconomic status has been identified as one of the most important demographic and social determinants of older adult health. The relationship has not been well studied or contrasted across much of the developing world. Yet, with population aging occurring rapidly in much ...Physical functioning; Older adult health2003
74 Adler, Frederick R.How virulent should a parasite be to its vector?Vector-borne parasites are commonly predicted to be less virulent to the vector than to the definitive host as the parasite gains little by harming its main route of transmission. Here we assess the empirical evidence from systems in which insects are vectors for vertebrate, plant, and invertebrate ...Parasite virulence; Hosts; Vector-borne parasite2003
75 Hawkes, KristenHuman life histories: primate trade-offs, grandmothering socioecology, and the fossil recordHuman life histories differ from those of other animals in several striking ways. Recently Smith and Tompkins (1995, p. 258) highlighted the combination of "slow" and "fast" features of human lives. Our period of juvenile dependency is unusually long, our age at first reproduction is late, and we h...Meat; Maturity; Life Span2003
