Method of continued fractions for complex potentials

Physical Review A, 1986
We show how a method of continued fractions of Hor\'ac\ifmmode \check{}\else \v{}\fi{}ek and Sasakawa for solving the Lippman-Schwinger equation for a local or nonlocal potential [Phys. Rev. A 30, 2274 (1984)] should be modified for the case of complex potentials. A nonlocal complex potential for the scattering of electrons from the helium atom is used

Potential Carcinostatic Activity of Metal Complexes

1978
For several years, there has been considerable controversy about the question of whether certain forms of cancer in humans are caused by viruses. Luria(1) indicated in 1960 that there was already considerable evidence that many tumors have viruses associated with them. In 1966, Kirschner et al.(2) proposed that certain complexes of the heavy transition

Streamfunction and Complex Potential

2007
The streamfunction is another mathematical construct that is of high importance for models using analytical solutions. Together with the potential the streamfunction enables the visualization of flow patterns that can hardly be produced by other methods.

Evoked potential analysis by complex demodulation

Electroencephalography and Clinical Neurophysiology, 1972
Abstract The method of the Fourier transform and that of complex demodulation are compared and contrasted, with special attention devoted to the question of frequency resolution. A computational method is described for complex demodulation. A discussion is given of the relevance of spectral analysis to the study of averaged (visual) evoked responses.

Anti-cancer potential of gold complexes

Inflammopharmacology, 2008
A full range of gold compounds is currently being investigated for their potential as anti-tumor agents. Gold(I) compounds related to the anti-arthritic drug continue to attract attention, especially those carrying biologically active molecules with anti-tumor activity in their own right.

Aminophosphonate Metal Complexes of Biomedical Potential

Current Medicinal Chemistry, 2013
Metals and their complexes with organic ligands have an important role in biochemical systems such as enzymatic catalysis, metal ion transfer across the cell membranes, treatment of malignancy, rheumatoid arthritis, ulcer and other types of diseases. Special attention is directed to metal complexes with ligands which are important in biological systems,

Schrödinger Operator with a Complex Steplike Potential

Journal of Differential Equations
The purpose of this article is to study pseudospectral properties of the one-dimensional Schrödinger operator perturbed by a complex steplike potential. By constructing the resolvent kernel, we show that the pseudospectrum of this operator is trivial if and only if the imaginary part of the potential is constant. As a by-product, a new method to obtain
