The first successful use of helicopter-assisted boma capture of African wild dogs Lycaonpictus is reported. Techniques used, effort expended and success rate achieved, are described. The first attempt to catch a particular pack is likely to be the mo

The discretization of Maxwell’s equations using finite diVerence time domain (FDTD) methods produces real space‐time equations that scale linearly with the system size, N. We present such an order-N scheme adapted to frequency-dependent dielectri

Using the recursive-Green-function (RGF) technique, we investigate the surface states of an electrified binary semiconductor, modelled by a chain of alternating s and p orbitals. The RGF provides the surface density of states (SDOS), which displays a

Electron transmission through an electrified composite metal-doped polymer-metal system is investigated by means of the Lippmann-Schwinger equation. The electric field, applied via the metal leads, acts across the polymer chain containing the single-

Chemisorption on an electrified finite chain of atoms ( electrochemisorption ) is investigated by the recursive Green-function (GF) technique, whereby the surface and adatom GFs can be expressed as ratios of Bessel functions. The Anderson-Newns model

Electron transmission properties of a configuration consisting of two infinite monatomic chains, which are coupled to each other by either a direct bond or through a finite atomic bridge, are studied via the tight-binding model. A method, based on th

The Wannier - Stark effect in electrified tight-binding systems is investigated, via the recursive Green-function technique, which involves repeated use of the Dyson equation. Green functions for finite, semi-infinite and infinite systems are generat

The electronic structure of an electrified finite chain of atoms is investigated by means of a recursive Green-function (RGF) method, whose iterative nature results in a continued-fraction form of the RGF, which can be written as a ratio of Bessel fu

A recursive Green-function (RGF) technique is used to study the surface states of an electrified solid. The concatenating nature of the method leads to a continued-fraction form of the RGF, which can be expressed as a ratio of Bessel functions. The s
