We consider current-induced domain wall motion and, the reciprocal process, moving domain wall-induced current. The associated Onsager coefficients are expressed in terms of scattering matrices. Uncommonly, in (Ga,Mn)As, the effective Gilbert damping coefficient $α_w$ and the effective out-of-plane spin transfer torqu…

The transmembrane protein FeoB plays a key role in ferrous iron acquisition in prokaryotes. The N-terminal domain of FeoB from Methanococcus jannaschii was overproduced, purified to homogeneity and crystallized in the presence of GTP and magnesium. The native protein crystallized in a tetragonal space group and the cr…

We describe a detailed photon correlation Fourier spectroscopy (PCFS) study of a single CdSe/ZnS nanocrystal at 10 K. PCFS provides the temporal and spectral resolution that is necessary for such a fast spectrally diffusing emitter. In the emitter spectrum, we distinguish a main 6 μeV zero-phonon line, the one- and tw…

In this study, a new approach for genetic algorithm (GA) is proposed and compared with conventional GA (CGA) in the weight optimisation of a 2-MVA salient pole synchronous machine. The main differences between the two algorithms are that, in the newly proposed method, individuals are paired and crossed over based on t…

A theoretical model is proposed for elastic stress relaxation of a buried strained cylindrical inhomogeneity, which assumes the edge misfit dislocation dipole formation in the soft matrix at some distance from the interface. The critical radius of the inhomogeneity for the formation of the edge misfit dislocation dipo…

The adsorption of atomic Au on the (001) surface of TiC, ZrC, HfC, VC, NbC, TaC, and delta-MoC and the mechanism of diffusion of this adatom through the surface have been studied in terms of a periodic density functional theory based approach. In all the cases, the Au adsorption energies are in the range of 1.90-2.35…

Guanidine compounds have important biochemical properties. Aminoguanidine, as an example, is an anti-oxidant, a nitric oxide synthase inhibitor (NOS) which prevents nitric oxide formation, and an inhibitor of advanced glycosylation end products (AGEs). As an anti-oxidant, aminoguanidine may affect the formation of ath…

Amino groups were introduced onto a poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) surface by applying 1,6-hexanediamine treatment. The effects of aminolysis time and 1,6-hexanediamine concentration on hydrophilicity of the treated PHBV were investigated using contact angle measurement. The occurrence of the amin…
