A high‐temperature pulsed solenoid valve for supersonic jet introduction up to 550 °C
(The American Institute of Physics, 1989-03)
A pulsed solenoid valve which can operate up to 550 °C has been designed for supersonic jet introduction. This valve uses a novel design where the nozzle head, which serves as the hot oven, and the solenoid operator are ...
Neutrino magnetic moment in the SU(3)L x U(1) model
(Elsevier, 1989-07-13)
We discuss the prospect and difficulties of having a neutrino with a large magnetic moment and a naturally small mass in the SU(3)L x U(1) model.
Metabolic fate of the heart agent [18F]6-fluorometaraminol
(Elsevier, 1989)
Studies were performed to determine whether [18F]6-fluorometaraminol (18F-FMR), a new neuronal heart radiopharmaceutical, is metabolized in vivo and if the metabolites are taken up in heart. Rat, dog, baboon and guinea pig ...
Large earthquakes in the macquarie ridge complex: Transitional tectonics and subduction initiation
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1989-03)
While most aspects of subduction have been extensively studied, the process of subduction initiation lacks an observational foundation. The Macquarie Ridge complex (MRC) forms the Pacific-Australia plate boundary between ...
Generalized relations among N‐dimensional Coulomb Green’s functions using fractional derivatives
(The American Institute of Physics, 1989-10)
Hostler [J. Math. Phys. 11, 2966 (1970)] has shown that Coulomb Green’s functions of different dimensionality N are related by G(N+2)=OG(N), where O is a first‐order derivative operator in the variables x and y. Thus all ...
Lognormality of the scalar dissipation pdf in turbulent flows
(The American Institute of Physics, 1989-07)
It is shown that measurements of lower‐dimensional projections of the scalar gradient in an isotropic conserved scalar field ζ(x,t) are sufficient to construct the probability density function (pdf) for the true scalar ...
Search for B-decay to Higgs bosons for Higgs boson masses between 50 and 210 MeV/c2
(Elsevier, 1989-10-05)
We use data from the Mark II experiment at PEP to search for the process B-->h0X for mh0 between 50 and 210 MeV/c2. No evidence for the Higgs boson is seen in this mass range. The limit obtained rules out the standard ...
Canonical commutator and mass renormalization
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1989-11)
The question considered is the effect on the canonical commutation rules of mass renormalization in quantum electrodynamics. This is investigated by considering the quantum Langevin equation for a charged quantum oscillator ...
Gammatrica
(Elsevier, 1989-06-12)
Equations for strings and traces of strings of [gamma] matrices are summarized.
A note on multiple flow equilibria
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1989-12)
A set of ordinary differential equations describing a mechanical system subject to forcing and dissipation is considered. A topological argument is employed to show that if all time-dependent solutions of the governing ...
