126 Hansen, Charles D.; Wald, IngoInteractive isosurface ray tracing of time-varying tetrahedral volumesAbstract- We describe a system for interactively rendering isosurfaces of tetrahedral finite-element scalar fields using coherent ray tracing techniques on the CPU. By employing state-of-the art methods in polygonal ray tracing, namely aggressive packet/frustum traversal of a bounding volume hierarc...2007-11
127 Morse, Michael DavidSpectrosopic studies of jet-cooled NiAu and PtCuSpectroscopic investigations of NiAu and PtCu have revealed that both molecules possess 2?5/2 ground electronic states, and are in this respect analogous to the isovalent molecule NiCu. The ground-state bond lengths (r?) have been measured as 2.351?0.001 ? and 2.335?0.001 ? for NiAu and PtCu, respe...1992
128 Miller, Joel Steven; Epstein, Arthur J.Effect of solvent on the magnetic properties of the high-temperature V[TCNE]x molecule-based magnetThe different magnetic behaviors of the V[TCNE]x (TCNE=tetracyanoethylene) magnet prepared via the reaction of TCNE and V(CO)6 in CH2Cl2 and the solvent-free chemical vapor deposition (CVD) of TCNE and V(CO)6 onto a glass substrate were determined. It was shown that the presence of noncoordinating C...Magnetization; Molecule2001
129 Chaudhuri, Reaz A.Three-dimensional singular stress field at the front of a crack and lattice crack deviation (LCD) in a cubic single crystal plateA novel eigenfunction expansion technique, based in part on separation of the thickness variable, is developed to derive three-dimensional asymptotic stress fields in the vicinity of the front of a semi-infinite through-crack weakening an infinite plate made of a homogeneous cubic single crystal. C...2010-05-12
130 Mattis, Daniel C.Three-band model of high-Tc superconductivityWe reduce the three-band model of planar CuO2 to a single-band of composite fermions. We obtain hopping parameters teff(Rij), repulsive potentials Ueff and V(Ri j), and the superexchange interactions J(Ri j) necessary for both antiferromagnetism and superconductivity. The ratios of these quantitie...Copper oxides; Composite fermions; Charge transport; Bloch energies; Superexchange1999-03
131 Dailey, Andrew T.; Moore, Kevin R.Value of MR neurography for evaluating extraspinal neuropathic leg pain: a pictorial essaySummary: Fifteen patients with neuropathic leg pain referable to the lumbosacral plexus or sciatic nerve underwent high-resolution MR neurography. Thirteen of the patients also underwent routine MR imaging of the lumbar segments of the spinal cord before undergoing MR neurography. Using phased-array...MR neurography; Neuropathic leg pain; Extraspinal; Lumbosacral plexus2001
132 Brunvand, Erik L.Estimating performance of an ray- tracing ASIC designRecursive ray tracing is a powerful rendering technique used to compute realistic images by simulating the global light transport in a scene. Algorithmic improvements and FPGA-based hardware implementations of ray tracing have demonstrated realtime performance but hardware that achieves performance ...2006
133 Balasubramonian, RajeevDynamic memory hierarchy performance optimizationAlthough microprocessor performance continues to increase at a rapid pace, the growing processor-memory speed gap threatens to limit future performance gains. In this paper, we propose a novel configurable cache and TLB as an alternative to conventional two-level hierarchies. This organization le...Microprocessor performance; Processor-memory speed gap2000

136 Miller, Jan D.; Nalaskowski, JakubFlotation chemistry and technology of nonsulfide mineralsThe dimensions of nonsulfide flotation technology extend in many directions, as might be expected from the diversity of the mineral classes, which include soluble salt minerals (potash, borax, and trona), semisoluble salt minerals (phosphate minerals, fluorite, calcite, and barite), and insoluble ox...Flotation; Insoluble collectors; Salt minerals; Nonsulfide minerals2007
137 Sperry, John S.Water transport in vesselless angiosperms: conducting efficiency and cavitation safetyTwo structure-function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low-resistance torus-margo pits. Second, vesselless wood ought to be exceptionally safe from cav...2007
138 Balasubramonian, RajeevDynamically allocating processor resources between nearby and distant ILPModern superscalar processors use wide instruction issue widths and out-of-order execution in order to increase instruction-level parallelism (ILP). Because instructions must be committed in order so as to guarantee precise exceptions, increasing ILP implies increasing the sizes of structures s...Instruction-level parallelism; Microarchitecture; Primary thread; Future thread; Instruction reuse buffer2001
139 Wolfinger, Nicholas H.Shifting fortunes in a changing economy: trends in the economic well-being of divorced women*Income losses resulting from marital disruption have traditionally contributed to high rates of poverty for single women. This paper explores trends in the economic consequences of divorce using data from the 1980-2001 Current Population Survey March Demographic Supplement. Divorce still adversel...Divorce; Separation; Finances; Financial independence2003-10-01
140 Werner, Carol M.Service-learning "rules" that encourage or discourage long-term service: implications for practice and researchWe use research and theory on intrinsic motivation to suggest that some service-learning practices may be counter-productive. Although these practices may encourage student involvement in the short-term, they may reduce interest over the long-term. We pose seven questions about service requirements ...Community; Choice; Opportunities2000
141 Gale, Bruce K.Platinum functionalized titania nanotube array sensor for detection of Trichloroethylene in waterA sensor using platinum functionalized titania nanotubes for the detection of Trichloroethylene (TCE) in water samples has been developed. The titania nanotubes were synthesized using an electrochemical anodization technique and platinum was photocatalytically deposited on the nanotubes. The sensor ...2013-01-01
142 Mattis, Daniel C.Theory of superexchange in CuO2The limit method allows exact analysis of low-lying electronic states in a strong-coupling model Cu02 plane. We extend it to nonorthogonal orbitals and fit to a t-t'-J model. The superexchange parameter is J = g32t*, with the unit of energy and g3 a lumped parameter.Copper oxides; Superexchange1995-12
143 Parker, Steven G.; Hansen, Charles D.Distributed interactive ray tracing for large volume visualizationWe have constructed a distributed parallel ray tracing system that interactively produces isosurface renderings from large data sets on a cluster of commodity PCs.

145 Miller, Jan D.Surface phase transitions of adsorbed collector molecules as revealed by in-situ FT-IR/IRS spectroscopyIt has been shown by inspection of FT-IR/IRS spectra that the alkyl conformation of adsorbed collectors can be determined. The conformations of adsorbed collectors were interpreted in terms of bulk solution phases of the collectors. Such analysis was performed on the CaF2/oleate, A1203/SDS and KC1/...Oleates; Micellar; In situ analysis; Adsorption1993
146 Miller, Jan D.Zinc-dust cementation of silver from alkaline cyanide solutions - analysis of plant dataThe direct recovery of precious metals from alkaline cyanide solution is frequently accomplished by the well-established Merrill-Crowe process involving zinc-dust cementation. This is particularly true for silver. Plant data from two operations are presented and analyzed in terms of intrinsic reacti...Zinc-dust; Silver; Alkaline cyanide; Merrill-Crowe1988
147 Mcpherson, Brian JamesOverpressures in the Uinta Basin, Utah: analysis using a three-dimensional basin evolution modelAbstract. High pore fluid pressures, approaching lithostatic, are observed in the deepest sections of the Uinta basin,Utah. Geologic observations and previous modeling studies suggest that the most likely cause of observed overpressure is hydrocarbon generation. We studied Uinta overpressure by dev...2001
148 Miller, Jan D.Air-sparged hydrocyclone (ASH) technology for cyanide recoveryAn air-sparged hydrocyclone (ASH) mobile system was evaluated for continuous stripping and recovery of cyanide (the AVR process) from process water at a gold plant site.

149 Wu, Yong-ShiGround-state degeneracy in the Levin-Wen model for topological phasesWe study the properties of topological phases by calculating the ground-state degeneracy (GSD) of the two-dimensional Levin-Wen (LW) model. Here it is explicitly shown that the GSD depends only on the spatial topology of the system. Then we show that the ground state on a sphere is always nondegener...2012-01-01
