One-dimensional inverse scattering problems: an asymmetric two-component wave system framework
(IOP Publishing Ltd, 1989-08-01)
Many one-dimensional inverse scattering problems can be formulated as a two-component wave system inverse problem, including inverse problems for lossless and absorbing acoustic and dielectric media. The advantage of doing ...
Quark mass effects and anomalies
(Elsevier, 1988-08-25)
When one takes into account that different quarks have unequal masses, five-point functions associated with pentagon graphs with two external gluons (2g) are modified by terms involving quark mass ratios. In this context ...
28 GeV/c beam experiments
(The American Institute of Physics, 1981-02)
Three experiments that were run concurrently at the Brookhaven AGS are reviewed and compared. The experiments searched for prompt neutrinos and penetrating neutral particles from a beam dump exposed to 4.2×1018 28 GeV/c ...
Design of a pulsed valve for high‐pressure NH3 injection into supersonic beam/mass spectrometry
(The American Institute of Physics, 1988-11)
A novel design of a pulsed valve for high‐pressure injection of NH3 for supersonic jet expansions is presented. This valve can operate up to 200‐atm reservoir pressure at 180 °C with a pulse width down to 100 μs. This valve ...
A captive solvent method for rapid N-[11C]methylation of secondary amides: Application to the benzodiazepine, 4'-chlorodiazepam (RO5-4864)
(Elsevier, 1988)
[11C]4'-Chlorodiazepam (RO5-4864), for PET studies of peripheral benzodiazepine receptors, was synthesized by alkylation of 1-desmethyl-4'-chlorodiazepam, in a small volume of acetone adsorbed on acrylic yarn, with [11C]methyl ...
CT findings of hypervascular malignant peritoneal mesothelioma
(Elsevier, 1987)
A case of peritoneal mesothelioma is presented in which CT demonstrated abnormal regions of increased vascularity in the omentum corresponding to hypervascular omental lesions shown by angiography. This CT appearance has ...
On the similarity solutions to laminar natural convection boundary layers
(Elsevier, 1986-02)
The supersymmetric QCD and KL-KS mass difference
(Elsevier, 1984-01-26)
Assuming that globally supersymmetric QCD accounts for the discrepancy between the experimental value of the KL-KS mass difference and that obtained from the electroweak model, we extract constraints on the squark masses ...
New results from Bhabha scattering at 29 GeV
(Elsevier, 1986-01-23)
Results are reported on a high statistics study of Bhabha scattering at 29 GeV in the polar angle region, |cos [theta]| gv2 = 0.03 +/- 0.09 and ga2 = 0.46+/-0.14. Limits on the QED-cutoff parameters are [Lambda]+ > 154 ...
The lepton mixing matrix in a composite model
(Elsevier, 1981-08-20)
A generalized mixing matrix for leptons is presented based on a composite model of quarks and leptons. The mixing matrix is expressed in terms of one parameter, which is determined either by discussing that it is identical ...
