Generalized parastatistics and internal symmetry
(The American Institute of Physics, 1983-06)
We exhibit generalized parastatistical double commutation relations which allow a solution less restrictive than Green’s ansatz. This leads to local interaction terms in the Lagrangian consistent with an internal symmetry ...
Workshop on acceleration of polarized protons: summary report
(The American Institute of Physics, 1983-03-15)
Computed tomography of malignant tumors of the osseous pelvis
(Elsevier, 1983)
The medical records, conventional radiographs, bone scans and pelvic CT scans obtained in 50 consecutive patients with malignant lesions involving the osseous pelvis were retrospestively reviewed. In 21 patients with primary ...
Analysis of the low temperature fluorescence and phosphorescence spectra of p-difluorobenzene
(Elsevier, 1983-11)
The low temperature fluorescence spectra (4.2 K) of solid solutions of p-difluorobenzene-h4 (pDFB-h4) and -d4 have been recorded and analyzed. The absence of fluorescence from vibrationally excited states at 4.2 K eliminates ...
Boundary conditions for the solution of compressible navier-Stokes equations by an implicit factored method
(Elsevier, 1983-10)
A method is presented for formulating the boundary conditions in implicit finite-difference form needed for obtaining solutions to the compressible Navier-Stokes equations by the Beam and Warming implicit factored method. ...
More on the axial anomaly in supersymmetric Yang-Mills theory
(Elsevier, 1983-03-24)
The compatibility of the Adler-Bardeen theorem with the supermultiplet containing the axial, trace, and supercurrent anomalies in N = 1 supersymmetric Yang-Mills theory is re-examined (in component form). It is argued that ...
A second generalized equipartition theorem@fa@f)
(The American Institute of Physics, 1983-02-01)
An extension of Tolman’s generalized equipartition theorem, allowing the calculation of the mean‐square energy and its fluctuations, is demonstrated. Several examples, not all in canonically conjugate coordinate systems, ...
Synthesis of [18F]perchloryl fluoride and its reactions with functionalized aryl lithiums
(Elsevier, 1983-03)
[18F]Perchloryl fluoride (18FClO3) has been synthesized by the reaction of [18F]F2 with KClO3 and its synthetic utility demonstrated by the successful syntheses of [18F] labeled 2-fluoroaniline, 2-fluoroanisole, ...
Supergravity and the inverted gauge hierarchy
(Elsevier, 1983-02-17)
We generalize a class of O'Raifeartaigh models with Witten's inverted gauge hierarchy to N = 1 supergravity. Radiative corrections induce a grand unification scale that is several orders of magnitude below the Planck mass. ...
Growth of high purity single crystals of arsenic
(Elsevier, 1983-06)
Large, high quality, single crystals of arsenic have been grown from the melt in a high pressure bomb made from synthetic quartz. The crystals have residual resistance ratios (RRR) of up to 5500, the largest reported to date.
