On the classical limit of phasespace formulation of quantum mechanics : entropy
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.
Magnetic susceptibility of a two-dimensional electron gas in the strong magnetic field limit and for non-zero temperatures
Analytic expressions are derived for the magnetic susceptibility and the Fermi energy of a non-interacting two-dimensional electron gas in the strong field limit and for non-zero temperatures. The results at zero temperature ...
Ideal two-dimensional electron gas in a magnetic field and at non-zero temperatures : an alternative approach
A new exact expression is derived for the free energy of an ideal two-dimensional electron gas (2DEG) in a uniform magnetic field and at low, but finite, temperatures. The approach eliminates a 2D-peculiarity that neither ...
The specificity and catalytic properties of Alu I methylase
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 Maxam-Gilbert DNA ...
Purification and characterization of Alu I methylase
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, DEAE-cellulose, ...
Electronic structures of superlattices under in-plane magnetic field
The electronic structures of superlattices under an in-plane 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
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 “closed-form heave solutions for expansive soils”
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 ...
