Borel singularities at small xx
(The American Institute of Physics, 1997-04-20)
D.I.S. at small Bjorken xx is considered within the dipole cascade formalism. The running coupling in impact parameter space is introduced in order to parametrize effects that arise from emission of large size dipoles. ...
Ideal magnetofluid turbulence in two dimensions
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-05)
A continuum model of coherent structures in two-dimensional magnetohydro-dynamic turbulence is developed. These structures are macroscopic states which persist among the turbulent microscopic fluctuations, typically as ...
Vortex ring generation due to the coalescence of a water drop at a free surface
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-03)
Results are presented of an experimental investigation of vortex ring formation by a fluid drop contacting a free surface with negligible velocity. The pool fluid is mixed with fluorescein dye, and a laser sheet is used ...
Secure synthesis and activation of protocol translation agents
(IOP Publishing Ltd, 1997-12-01)
Protocol heterogeneity is pervasive and is a major obstacle to effective integration of services in large systems. However, standardization is not a complete answer. Standardized protocols must be general to prevent a ...
Dynamic behavior of the monomer–monomer surface reaction model with adsorbate interactions
(The American Institute of Physics, 1997-11-08)
The monomer–monomer surface reaction model with an adsorbate interaction term is studied. An epidemic analysis of the poisoning times (tp)(tp) for small square lattices as a function of lattice edge length LL and interaction ...
Electron–phonon interactions in CsCdBr3:Yb3+CsCdBr3:Yb3+
(The American Institute of Physics, 1997-10-01)
Pronounced electron–phonon coupling is observed for the 2F7/2↔2F5/22F7/2↔2F5/2 4f4f transitions of Yb3+Yb3+ doped into CsCdBr3.CsCdBr3. A comparison of the Raman spectrum and the luminescence excitation sideband accompanying ...
Blind deconvolution of sources from the transmission responses of one-dimensional inhomogeneous continuous and discrete layered absorbing media
(IOP Publishing Ltd, 1997-08-01)
Non-destructive testing and reconstruction of lossy non-uniform transmission lines require solving inverse scattering problems for inhomogeneous one-dimensional (1D) lossy media. Often the source waveform used to probe the ...
Paramagnetically induced nuclear magnetic resonance relaxation in solutions containing S ≥ 1S⩾1 ions: A molecular-frame theoretical and physical model
(The American Institute of Physics, 1997-11-15)
The enhancement of nuclear magnetic resonance (NMR) relaxation rates produced by paramagnetic solutes is physically rather different for electron spin S = 1/2S=1/2 paramagnetic species than for S ≥ 1S⩾1 species due to the ...
Searching for time reversal invariance violation in polarized neutron decay
(The American Institute of Physics, 1997-05-20)
Time reversal invariance violation is tightly constrained in the Standard Model, and the existence of a T-violating effect above the predicted level would be an indication of new physics. A sensitive probe of this symmetry ...
Computerized classification of malignant and benign microcalcifications on mammograms: texture analysis using an artificial neural network
(IOP Publishing Ltd, 1997-03-01)
We investigated the feasibility of using texture features extracted from mammograms to predict whether the presence of microcalcifications is associated with malignant or benign pathology. Eighty-six mammograms from 54 ...
