Presented are intra- and inter-observer variability data comparing the unique-hue (UH) selections of sets of males and females, using two different visual experimental procedures incorporating Munsell color chips of varying hue but identical chroma and value. Although 34 of the 40 Munsell hue chips were selected by at least one observer as a UH, selections were generally repeatable. In addition...

BACKGROUND We developed and compared 2 different methods for quantifying uracil (U) and dihydrouracil (UH(2)) in BSA and human plasma. Special attention was paid to the selectivity/specificity and the absence of a matrix effect. The UH(2)/U ratio is intended as a biomarker to identify patients with deficiency in 5-fluorouracil metabolism. METHODS We quantified U and UH(2) with 2 liquid chroma...

Two types of unit hydrograph (UH) are discussed, with an emphasis on uncertainties. The paper reviews the 1-parameter triangular unit hydrograph (UH) employed to assist with systematic design flood hydrograph estimation for ungauged United Kingdom catchments. A 6-parameter rainfall-runoff model that incorporates a 3-parameter UH is also discussed. The precision and accuracy of characteristic de...

The ability of some strains of Vibrio parahaemolyticus to hydrolyze urea (uh+) can be used as a marker to predict which strains isolated from molluscan shellfish harvested in the Pacific Northwest are potentially pathogenic. The thermostable direct hemolysin-producing (TDH+) characteristic is a marker that is correlated with potential pathogenicity, and all of the TDH+ strains that we have isol...

Satellite laser ranging (SLR) had been operated at a pulse repetition frequency (PRF) from ?10 Hz to 10 kHz; the ultra-high PRF of SLR (UH-SLR) is trend development. In this study, an alternate working mode firing and gated bursts proposed solve problem echo interference by backscattering. Through 200-kHz picosecond green with single-pulse energy 80 ?J width ps gate device, UH-SLR has built ape...

A method of construction of C-ultrahomogeneous (or C-UH) graphs is applied to the Biggs-Smith graph, which is seen in the process to be a {C9}P4 -UH graph and a { ~ C9} ~ P4 -UH digraph, in order to demonstrate the existence of a connected edge-disjoint union Y of 102 tetrahedra (K4 s), or also union Y of 102 cuboctahedra (L(Q3) s) with no common 4-cycles, possesing a C-UH property for C = {K4}...

If u denotes a local, spatial average of u, then u′ = u − u is the associated fluctuation. Consider a time relaxation term added to the usual finite element method. The simplest case for the model advection equation ut + −→a · ∇u = f(x, t) is (uh,t + −→a · ∇uh, vh) + χ(uh, v′ h) = (f(x, t), vh). We analyze the error in this and (more importantly) higher order extensions and show that the added ...

In this paper, we show that the piecewise linear finite element solution uh and the linear interpolation uI have superclose gradient for tetrahedral meshes, where most elements are obtained by dividing approximate parallelepiped into six tetrahedra. We then analyze a post-processing gradient recovery scheme, showing that the global L2 projection of ∇uh is a superconvergent gradient approximatio...
