A Molecular Dynamics Study

by Harshad Joshi

Processive enzymes are a special class of enzymes which presumably remain attached to their polymeric substrates between multiple rounds of catalysis. Due to this property, the substrate slides along the enzyme and reduces the time for the random diffusional enzyme-substrate encounters thereby increasing the ...

The Kiloparsec-Scale Structure and Kinematics of High-Redshift ...

by David R. Law

We study the spatially resolved properties of star-forming galaxies at redshift z ~ 2 - 3 on scales ~ 1 kpc using a combination of morphological and kinematic analyses in an effort to characterize the major mechanisms of galaxy formation in the young universe. Using a sample of 216 galaxies which have been ...

A Multi-Wavelength Census of Star Formation at Redshift z~2

by Naveen A. Reddy

We examine the census of star-forming galaxies and their extinction properties at redshift z~2, when a large fraction of the stellar mass in the universe formed. We find a good agreement between the X-ray, radio, and de-reddened UV estimates of the average star formation rate (SFR) for our sample of z~2 galaxies ...

The Manufacture of High Temperature Superconducting Tapes and Films

by Kurt A. Richardson

The phenomena of superconductivity has enormous industrial potential, but the penetration of superconductor-based products has, thus far, been slow. An indisputable fact is that there are prizes, and profits, for the teams that solve the critical problems in understanding and processing these complex materials. The ...

An Improved Form for the Electrostatic Interactions of ...

by Nicholas V. Sushkin

The electrostatic interaction between two charged spheres in the presence of a screening electrolyte is calculated at the level of the linearized Debye-Hückel theory. The calculation is performed analytically as a multipole expansion by applying two-center spherical harmonic expansions and symbolic ...

Electronic and Optical Properties of Semiconductors

A Study Based on the Empirical Tight Binding Model

by Lok C. Lew Yan Voon

This study is a theoretical investigation of the electronic and optical properties of intrinsic semiconductors using the orthogonal empirical tight binding model. An analysis of the bulk properties of semiconductors with the zincblende, diamond and rocksalt structures has been carried out. We have extended the work ...
