Methods using o-alkylguanine-dna alkyltransferases

Kai Johnsson, Antje Keppler

A method using O-alkylguanine-DNA alkyltransferases (AGT) is disclosed for transferring a label from a substrate to a fusion protein comprising the AGT. This allows the detection and/or manipulating of the fusion protein, both in vitro and in vivo, by a ...

Unified approach for the explanation of stochastic and periodic moires

Isaac Amidror

Moire phenomena of different types are frequently encountered in electronic imaging. Most common are moire effects that occur between periodic structures. These effects have been intensively investigated in the past, and their mathematical theory is today ...

SPIE-Int. Soc. Opt. Eng2003

Incommensurate structure of Hexamethylenetetramine suberate (C6H12N4)(HOOC-(CH2)6-COOH) has been solved from single crystal x-ray diffraction data. A molecular dynamics simulation of this system was carried out from 15 K to 580K. A second-generation consis ...

Ground states of dispersion-managed nonlinear Schrodinger equation

Jan Sickmann Hesthaven

An exact pulse for the parametrically forced nonlinear Schrodinger equation (NLS) is isolated. The equation governs wave envelope propagation in dispersion-managed fiber lines with positive residual dispersion. The pulse is obtained as a ground state of an ...

AMERICAN PHYSICAL SOC2000

A new approach is presented for investigating the superposition of any number of periodic structures, and the Moire effects which may result. This approach, which is based on an algebraic analysis of the Fourier-spectrum using concepts from the theory of g ...

Density-functional perturbation theory for lattice dynamics with ultrasoft pseudopotentials

Alfredo Pasquarello

We generalize density-functional perturbation theory for lattice dynamics to Vanderbilt's ultrasoft pseudopotential scheme. This formulation accounts for the nonorthogonality of the orbitals, the augmentation of the electron density, and the dependence of ...

1997

This thesis is devoted to the theoretical study, by ab initio numerical methods, of the physical properties of substitutional semiconductor alloys. Nowadays, ab initio numerical methods allow to study quite accurately the physical properties of moderately ...

Cage effect on the photodissociation of small molecules in rare gas matrices

Majed Chergui

Photodissocn. of H2O (D2O) and Cl2 trapped in rare gas matrixes was studied in relation to the cage effect. Barrier energies for the exit of the fragments from the matrix cage were detd., together with the excess kinetic energy dependence of the photodisso ...

1992

The cluster beam technique offers promise of becoming a useful tool for chemists in their search for new compounds. Using this technique elemental vapors can be made to react under controlled conditions to form units of condensed matter (clusters) small en ...
