An ultra‐cold jet of polarized atomic hydrogen
(The American Institute of Physics, 1988-11-20)
Equipment is being tested to determine the applicability of cryogenic atomic physics techniques to the production of dense polarized atomic hydrogen beams. Such beams, with expected densities of 1014/cm3, would be useful ...
NMDA receptor channels: Labeling of MK-801 with iodine-125 and fluorine-18
(Elsevier, 1988)
Methods for labeling the glutamate channel blocking agent MK-801 with iodine-125 (125I) and fluorine-18 (18F) are described. Radioiodine was incorporated in the 1- or 3-positions of the aromatic ring of (+/-)MK-801 by ...
Observations of teleseismic P wave coda for underground explosions
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1988-03)
The early P wave coda (5–15 sec after the first arrival) of underground explosions at the Nevada Test Site is studied in the time domain using 2082 teleseismic short-period recordings, with the intent of identifying ...
Energy‐dependent collisional deactivation of vibrationally excited azulene
(The American Institute of Physics, 1988-05-15)
Collisional energy transfer parameters for highly vibrationally excited azulene have been deduced from new infrared fluorescence (IRF) emission lifetime data with an improved calibration relating IRF intensity to vibrational ...
Identification of spatially discontinuous parameters in second-order parabolic systems by piecewise regularisation
(IOP Publishing Ltd, 1988-10-01)
A novel piecewise regularisation approach has been developed for the identification of spatially discontinuous parameters in second-order parabolic systems. First, previous results on the regularisation identification ...
Improved radioimmunolocalization of human tumor xenografts following subcutaneous delivery of monoclonal antibodies
(Springer-Verlag, 1988-01)
The localization of a radiolabeled murine monoclonal antibody reactive with choriocarcinomas to human choriocarcinoma xenografts following intravenous and subcutaneous injection was evaluated by gamma scanning and tissue ...
Mass predictions from the Garvey-Kelson mass relations
(Elsevier, 1988-07)
Part A: The transverse Garvey-Kelson mass relation represents a homogeneous third-order partial difference equation. Procedures are described for estimating masses of nuclei with N [ges] Z from the most general solution ...
Masses from an inhomogeneous partial difference equation with higher-order isospin contributions
(Elsevier, 1988-07)
In the present work, a mass equation obtained as the solution of an inhomogeneous partial difference equation is used to predict masses of unknown neutron-rich and proton-rich nuclei. The inhomogeneous source terms contain ...
Theoretical investigation of hole transport in strained III‐V semiconductors: Application to GaAs
(The American Institute of Physics, 1988-08-29)
A Monte Carlo method has been developed and applied to study the anisotropic transport of holes in unstrained and strained bulk III‐V compound semiconductors. In this letter, we present the results for the prototypical ...
A grey transport acceleration method far time-dependent radiative transfer problems
(Elsevier, 1988-10)
A new iterative method for solving the time-dependent multifrequency radiative transfer equations is described. The method is applicable to semi-implicit time discretizations that generate a linear steady-state multifrequency ...
