Regional 2-[ 18 F]fluoro-2-deoxy- d -glucose uptake varies in normal lung
(Springer-Verlag, 1996-05)
2-[ 18 F]fluoro-2-deoxy- d -glucose positron emission tomography (FDG-PET) is a promising imaging procedure for detecting primary and metastatic cancer in the lungs. We have, however, failed to detect some small tumors in ...
A three-dimensional model for the probabilistic intergranular failure of polycrystalline arrays
(IOP Publishing Ltd, 1996-05-01)
A three-dimensional grain model, in which the grains are represented by regular truncated octahedra, has been developed to study probabilistic time-dependent intergranular failure in polycrystalline arrays. In this model, ...
Fermi surfaces and single-particle spectral functions of low-dimensional inorganic non-cuprate compounds: the molybdenum bronzes
(IOP Publishing Ltd, 1996-11-25)
The Fermi surfaces and single-particle spectral functions of several low-dimensional materials have been measured as part of an effort to assess the occurrence of non-Fermi-liquid behaviour in non-cuprate materials.
Nonisothermal model of glass fiber drawing stability
(Steinkopff-Verlag; Springer Science+Business Media, 1996-11)
Draw resonance is caused by a constant speed winder that leads to non-constant axial forces (Schultz, 1984). The well studied isothermal Newtonian fiber drawing predicts very modest critical draw ratios (around 20, much ...
On the pointwise behavior of semi-classical measures
(Springer-Verlag, 1996-01)
In this paper we concern ourselves with the small ħ asymptotics of the inner products of the eigenfunctions of a Schrödinger-type operator with a coherent state. More precisely, let ψ j ħ and E j ħ denote the eigenfunctions ...
LETTER TO THE EDITOR: String fluid dynamics
(IOP Publishing Ltd, 1996-02-01)
We present the general energy - momentum tensor for a dynamical string fluid and show that it predicts that strings are very strong during early cosmological times, weak after the inflationary period, and negligible during ...
Linear viscoelastic behavior of copper phthalocyanine dispersions used in printing inks
(Steinkopff-Verlag; Springer Science+Business Media, 1996-07)
In this paper we describe the linear viscoelastic properties of copper phthalocyanine (CuPCN) dispersions that are used in the manufacturing of offset lithographic printing inks. Transmission electron microscopy shows that ...
Scalar imaging velocimetry measurements of the velocity gradient tensor field in turbulent flows. II. Experimental results
(The American Institute of Physics, 1996-07)
Scalar imaging velocimetry is here applied to experimental turbulent flow scalar field data to yield the first fully resolved, non‐intrusive laboratory measurements of the spatio‐temporal structure and dynamics of the full ...
Collisional deactivation of highly vibrationally excited pyrazine
(The American Institute of Physics, 1996-07-22)
The collisional deactivation of vibrationally excited pyrazine (C4N2H4) in the electronic ground state by 19 collider gases was studied using the time‐resolved infrared fluorescence (IRF) technique. The pyrazine was ...
Resistive destabilization of cycloidal electron flow and universality of (near‐) Brillouin flow in a crossed‐field gap
(The American Institute of Physics, 1996-12)
It is shown that a small amount of dissipation, caused by current flow in a lossy external circuit, can produce a disruption of steady‐state cycloidal electron flow in a crossed‐field gap, leading to the establishment of ...
