The quasi-TEM approximation for multiconductor lines embedded in inhomogeneous bi-isotropic media is developed. It is shown that in the quasi-TEM limit a multiconductor line in bi-isotropic media can be represented by a coupled set of nonreciprocal and nonsymmetric circuit transmission lines. The effect on the circuit…

Eight species of halophilic Archaea were tested for the presence of isocitrate lyase activity. High activities (up to 100 nmol min−1 mg protein−1) were detected in Haloferax mediterranei and Haloferax volcanii when grown in medium containing acetate as the principal carbon source. Little activity was found in represen…

Two novel glass compositions aimed at improving the quantum efficiency and gain of the 1.3 mu m praseodymium-doped fibre amplifier (PDFA) were developed and investigated. The two glasses were compositions based on cadmium halide and gallium fluoride. Both bulk glass samples and core-clad fibre structures were fabricat…

We investigate the dependence of the average interface field on the inversion and depletion charge density through the use of a zero-temperature Green’s function formalism for the evaluation of the broadening of the electronic states and conductivity. Various models for the surface-roughness autocovariance function ex…

Spectroscopic absorption and emission measurements have been used to study laser deposition of YBCO films. They show that >95% of the monatomic Y and Ba initially ablated from the target undergo gas-phase chemical combination before film deposition. In contrast, considerable monatomic Cu persists into the deposition r…

A transition matrix method is commonly used to deal with the problems of either plane-wave scattering from or the Green's function of a generalized anisotropic medium. This method, although rigorous analytically, introduces numerical breakdown, when the layers are electrically thick and the waves are evanescent. A var…

In our previous paper [Phys. Rev. B 44, 2046 (1991)], results of high-resolution transmission electron microscopy (HRTEM) at each stage of the complicated hysteretic phase transformation of 1T-${\mathrm{TaS}}_{2}$ are described. Here, on warming from the commensurate (C) phase to the incommensurate (IC) phase, the tri…

A lattice-dynamics approach to acoustic emission during plastic deformation of crystals is proposed. First the dynamics of a dislocation interacting with transverse acoustic waves is investigated on the basis of a microscopic Frenkel–Kontorova model in which the rigidity of the substrate is relaxed. It is shown that t…

The preparation of 4′-alkyl- and 4′-alkoxy-4-cyano-3-fluorobiphenyls by four different procedures is described and discussed; the best method involves palladium(0)-catalysed coupling of arylboronic acids and 4-bromo-(or 4-iodo-)-2-fluorobenzonitrile. The effects on transition temperatures of fluoro substitution ortho…

An efficient algorithm is derived for generating all possible seamless carbon nanotube structure models. This makes use of multijugate helical lattices, a concept borrowed from some biological structures. Principles for helicity and structure analysis of carbon nanotubes using high-resolution electron microscopy and i…

The crystal quality of new nonlinear-optical/ferroelectric crystal LaBGeO5 was examined by measuring wavelength dependence of the second harmonic intensity under the phase matching condition at λ = 1.314 μm. The effective interaction length I eff was determined as 1.28 mm, which was 73% of the actual length. The ferro…

Abstract Irradiation of neat PVC at λ inc = 254 nm under air induces the formation of conjugated double bonds, (CHCH) n (quantum yield ϕ ≈︁ 1.6 · 10 −4 for n = 3). Simultaneously, CCl bonds are split (ϕ ≈︁ 8 · 10 −2 ). With the aid of FTIR spectroscopy the following oxidation products were detected: OH, CHCHC…

Theoretical investigation is made into ion sound propagation and damping in strongly coupled plasmas near the Wigner crystallization of the ion subsystem. Sound velocity grows with the strengthening of the coupling, and sound decay is due to ion viscosity. The transition from the collisional mechanism of viscosity to…
