Time dependence of a general class of quantum distribution functions
(1984)We derive an explicit analytic expression for the time development of a generalized class of quantum distribution functions, which include as special cases the Wigner, the normal, and the antinormal distributions. We find ... 
Phasespace representations of the Bloch equation
(1985)We discuss the phasespace representation of the Bloch equation and present analytic expressions for two generalized classes of distribution functions. Series solutions to order of ħ2 are given. We conclude that the Wigner ... 
The specificity and catalytic properties of Alu I methylase
(1985)The specific methylation site for Alu I methylase was the cytosine nucleotide in Alu I sequence. The position of the methylated cytosine nucleotide was determined by the chemical cleavage reactions of the MaxamGilbert DNA ... 
Purification and characterization of Alu I methylase
(1985)Alu I methylase has been isolated from 300g (wet weight) cells of Arthrobacter luteus. After ammonium sulfate fractionation, the protein which has methylase activity was purified through phosphocellulose, DEAEcellulose, ... 
Unsaturated soil consolidation theory and laboratory experimental data
(1986)The volume change process of an unsaturated soil was considered as a transient flow problem with water and air flowing simultaneously under an applied stress gradient. laboratory experiments were performed to study the ... 
Elastic light scattering from nucleated blood cells : rapid numerical analysis
(1986)A model is presented to calculate the lightscatter properties of nucleated blood cells which are mimicked by two concentric spheres. The lightscatter characteristics were derived from the RayleighDebyeGans approximation ... 
Surface effects on the diamagnetic susceptibility and other properties of a low temperature electron gas
(1986)A general formulation is developed for determining the free energy of a Fermi gas contained in an arbitrary smooth external potential barrier and in a weak magnetic field, in the lowtemperature limit. The Wigner phasespace ... 
On the classical limit of phasespace formulation of quantum mechanics : entropy
(1986)The classical limits of phase‐space formulation of quantum mechanics are studied. As a special example, some properties of both quantum mechanical and classical entropies are discussed in detail. 
The proper analytical solution of the Kortewegde VriesBurgers equation
(1987)On using variable transformations and proofs of theorems, the asymptotic behaviour and the proper analytical solution of the Kortewegde VriesBurgers equation have been found in this letter. 
Spectral analysis of flow cytometric data : design of a specialpurpose lowpass digital filter
(1987)Spectral decomposition of flow cytometric datafiles of arbitrary dimension reveal information of both the signal and the noise components that constitute the histograms. This spectral information is used to construct a ... 
Magnetic susceptibility of a twodimensional electron gas in the strong magnetic field limit and for nonzero temperatures
(1987)Analytic expressions are derived for the magnetic susceptibility and the Fermi energy of a noninteracting twodimensional electron gas in the strong field limit and for nonzero temperatures. The results at zero temperature ... 
Closedform heave solutions for expansive soils
(1988)During the past decade, the theory for heave prediction has developed within the context of unsaturated soil behavior and has become a valuable tool for geotechnical practice. The laboratory procedures for testing expansive ... 
Landaulevel width : magneticfield and temperature dependences
(1988)We calculate the effect of level broadening on the steady part of the magnetic moment and specific heat by deriving an analytic expression for the free energy of a twodimensional electron gas in a uniform magnetic field, ... 
Scattering matrix elements of biological particles measured in a flow through system : theory and practice
(1989)Light scattering techniques (including depolarization experiments) applied to biological cells provide a fast nondestructive probe that is very sensitive to small morphological differences. Until now quantitative measurement ... 
Ideal twodimensional electron gas in a magnetic field and at nonzero temperatures : an alternative approach
(1989)A new exact expression is derived for the free energy of an ideal twodimensional electron gas (2DEG) in a uniform magnetic field and at low, but finite, temperatures. The approach eliminates a 2Dpeculiarity that neither ... 
Electronic structures of superlattices under inplane magnetic field
(1989)The electronic structures of superlattices under an inplane magnetic field are studied by the method of expansion with sine functions. The electronic and hole magnetic energy levels are obtained as functions of kx,ky and ... 
Automatic indexing of medical literature using phrase matching: an exploratory study
(1989)This study sought to find out to what extent phrase matching could be used to automatically assign MeSH headings and subheadings to abstracts of journal articles. A phrase matching program was written using Turbo Prolog. ... 
Closure to “closedform heave solutions for expansive soils”
(1989)During the past decade, the theory for heave prediction has developed within the context of unsaturated soil behavior and has become a valuable tool for geotechnical practice. The laboratory procedures for testing expansive ... 
A pole sharing technique for linear phase switchedcapacitor filter banks
(1990)A switchedcapacitor pole sharing technique for implementing bandpass filter banks is proposed. Using this technique, hardware reduction is achieved in two ways. First, the efficient nonminimum phase Lerner filter approximation ... 
Detection of Listeria monocytogenes by using the polymerase chain reaction
(1990)A method was developed for detection of Listeria monocytogenes by polymerase chain reaction amplification followed by agarose gel electrophoresis or dot blot analysis with a 32Plabeled internal probe. The technique ...
