An Auxiliary RF Channel with Convenient Phase Control for NMR Spectrometers
(Elsevier, 1993-09)
Holography, diffeomorphisms, and scaling violations in the CMB
(IOP Publishing Ltd, 2004-07-01)
We analyze diffeomorphism invariance in inflationary spacetimes regulated by a boundary at late time. We present the action for quadratic fluctuations in the presence of a boundary, and verify that it is gauge invariant ...
Absence of goldstino decoupling in hierarchical superunified models
(Elsevier, 1983-08-25)
It is shown that there exist a class of hierarchical supersymmetric unified models in which the Goldstino field does not decouple from that light states. We illustrate this with an SUN model. The phenomenology and cosmology ...
Measurement of sonic velocity in liquid Refrigerant 12
(The American Institute of Physics, 1977-08)
The sonic velocity in subcooled liquid Refrigerant 12 (CCl2F2) was measured at 26.7 °C using an apparatus designed to investigate transients associated with pipe blowdown. The mean value for sonic velocity obtained from ...
Efficient algorithms for estimating the width of nearly normal distributions
(Elsevier, 1983-06-15)
Typical physics data samples often conform to Gaussian distributions with admixtures of more slowly varying backgrounds. Under such circumstances the standard deviation is known to be a poor statistical measure of distribution ...
Demographic Stochasticity in Evolutionary Biology.
(2013)
Demographic stochasticity, the random fluctuations arising from the intrinsic discreteness of populations and the uncertainty of individual birth and death events, is an essential feature of population dynamics. Nevertheless ...
Kinetics and fractal properties of the random sequential adsorption of line segments
(IOP Publishing Ltd, 1990-11-07)
The random sequential adsorption (RSA) of infinitely-thin line segments is studied by computer simulation. It is shown that the exponent for the time dependence of the surface coverage increases beyond the value 0.33, ...
Organic Photovoltaic Cells: From Performance Improvement to Manufacturing Processes
(Wiley Periodicals, Inc.Springer, 2015-05)
S-wave non-leptonic decays and gauge fields
(Elsevier, 1970-11-01)
S-wave non-leptonic decay amplitudes are obtained from a gauge-field model and the results are also interpreted from the point of view of mixing of particle fields. The model gives different effective enhancements for K- ...
