Ring, Terry Arthur | Verification of analytic energy moments for the one-dimensional energy dependent neutron diffusion equation with MCNP5 and Attila-7.1.0 | The energy dependent neutron diffusion equation (EDNDE) is converted into a moment equation which is solved analytically for the 1-D problem of a bare sphere of pure 235U. The normalized moments 0-5 generated analytically are compared to normalized energy moments, from Monte Carlo N Particle 5 versi... | 2012-01-01 | |

Sperry, John S. | Vulnerability to xylem cavitation and the distribution of sonoran desert vegetation | We studied 15 riparian and upland Sonoran desert species to evaluate how the limitation of xylem pressure (Vx) by cavitation corresponded with plant distribution along a moisture gradient. Riparian species were obligate riparian trees (Fraxinus velutina, Populus fremontii, and Salix gooddingii), nat... | Comparative approach; species distribution; xylem conducting efficency | 2000 |

Miller, Jan D. | Dispersed oil impact on froth stability in flotation | Foam stability in flotation has been studied for more than half of the last century, however, the mechanisms responsible for the defoaming action of many presently used reagents are not completely understood. This research presents oil flotation data, which may be used in the evaluation of aqueous ... | Particles; Defoaming; Surfactants | 2001 |

Lowrance, Edward | On the early development of Stagnicola Kingi (Meek) the Utah Ribbed Snail | General interest in the subject of molluscan embryology has continued in part because of the relation of its problems and processes to those of adult anatomy and ph_ysiology and in part because of its promise of light on the dynamic, developmental process itself. Attention was called to the present ... | 1934-03 | |

DeTar, Carleton | QCD thermodynamics with two flavors of Wilson quarks at Nt=6 | We report on a study of hadron thermodynamics with two flavors of Wilson quarks on 123 X6 lattices. We have studied the crossover between the high- and low-temperature regimes for three values of the hopping parameter, K=0. 16, 0.17, and 0.18. At each of these values of K we have carried out spect... | Wilson quarks; Staggered quarks; Chiral symmetry; Phase transitions | 1992-11 |

Kniss, Joe; Riesenfeld, Richard F. | Visual summary statistics | Traditionally, statistical summaries of categorical data often have been visualized using graphical plots of central moments (e.g., mean and standard deviation), or cumulants (e.g., median and quartiles) by box plots. In this work we reexamine the box plot and its relatives and develop a new hyb... | Visual summary statistics; categorical data; box plot; hybrid summary plot | 2007 |

Li, Minqi | Dialogue on the future of China | Three Chinese scholars speak to the question: How do you think the June 4th movement of 1989 will be remembered-----as another May 4th 1919, the threshold of a period of general political awakening and turbulence, or instead as a Chinese version of 1848 or 1968 in Europe: a last spontaneous explosio... | China; Politics; Social conditions | 1999 |

Von Arnim, Rudiger Lennart | A global model of recovery and rebalancing | This paper presents an investigation of global recovery from the great recession and rebalancing of global external imbalances, using a global model of sixteen countries and composite regions. The model applies to the short run, and only to the real side. Key features are demand-driven output determ... | 2010-01-01 | |

Broughton, John | Homestead cave Ichthyofauna | Biological evidence on the climatic and hydrographic history of the intermountain region would be much richer, if we had more than the present dribble of paleontological data on the fishes (Hubbs and Miller, 1948, p. 25). In this passage from their landmark synthesis of historical fish biogeograph... | Homestead Cave; Ichthyofauna; Lake Bonneville | 2000 |

Carrier, David R. | Evidence for endothermic ancestors of crocodiles at the stem of archosaur evolution | Physiological, anatomical, and developmental features of the crocodilian heart support the paleontological evidence that the ancestors of living crocodilians were active and endothermic, but the lineage reverted to ectothermy when it invaded the aquatic, ambush predator niche. In endotherms, there i... | Endothermy; ectothermy; Archosaur evolution; Archosaurs; Crocodilian heart | 2004 |

DeTar, Carleton | Finite-size and quark mass effects on the QCD spectrum with two flavors | We have carried out spectrum calculations with two flavors of dynamical Kogut-Susskind quarks on four lattice sizes from 83X24 to 163 X 24 at couplings that correspond to chiral symmetry restoration for a lattice with six time slices. We estimate that the linear spatial sizes of the lattices range f... | Kogut-Susskind quarks; Hadron mass; Pion mass | 1993-11 |

Hansen, Charles D. | Flow charts: visualization of vector fields on arbitrary surfaces | We introduce a novel flow visualization method called Flow Charts, which uses a texture atlas approach for the visualization of flows defined over curved surfaces. In this scheme, the surface and its associated flow are segmented into overlapping patches, which are then parameterized and packed in ... | 2008-09 | |

Codding, Brian | Alternative aboriginal economies: Martu livelihoods in the 21st century | In the western deserts of Australia, hunting and gathering endures as an important social and economic activity. That foraging persists within the boundaries of developed industrialized nation states may come as a surprise to those who evaluate foraging as less profitable than agricultural, wage or ... | Aboriginal economics; Aboriginal foraging | 2015 |

McElreath, Richard | Are peasants risk-averse decision makers? | For decades, researchers studying small-scale, subsistence-oriented farmers have sought to explain why these "peasants" seem slow to acquire new technologies, novel agricultural practices, and new ideas from the larger societies that have engulfed them. The early work on this question suggested that... | Subsistance farmers; Risk-aversion; Risk-taking; Cultural conservatism; Cost-benefit analysis | 2002 |

Khan, Faisal Habib | Multiple-load-source integration in a multilevel modular capacitor-clamped DC-DC converter featuring fault tolerant capability | A multilevel modular capacitor-clamped dc-dc converter (MMCCC) will be presented in this paper with some of its advantageous features. By virtue of the modular nature of the converter, it is possible to integrate multiple loads and sources with the converter at the same time.
