Effect of transition metal cations on the local structure and lithium transport in disordered rock-salt oxides.

Lithium-excess oxides LiTiMnO and LiNbMnO with a disordered rock-salt structure and Mn/Mn as a redox couple were compared to analyze the effect of different d metal ions on the local structure and Li ion migration. These cathode materials were obtained by mechanochemically assisted solid-state synthesis. Using XRD, Li NMR and EPR spectroscopy and transmission electron microscopy it was shown that the Mn ions are prone to form clusters, while d metal ions are evenly distributed in the crystal lattice.

Synthesis of bismuth (III) oxofumarate and its solubility in organic solvents.

This paper present the synthesis of bismuth (III) oxofumarate (BiO)CHO by solution-solid reaction due to the interaction of basic bismuth nitrates [BiO(OH)](NO)·3HO and [BiO(OH)](NO)·HO with aqueous solutions of fumaric acid CHO. Solubility of (BiO)CHO in various organic solvents has been investigated. The morphology and phase composition of the samples was established by X-ray diffraction, scanning electron microscopy, thermogravimetric and chemical analyzes.

Assessing a multiple QTL search using the variance component model.

Development of variance component algorithms in genetics has previously mainly focused on animal breeding models or problems in human genetics with a simple data structure. We study alternative methods for constrained likelihood maximization in quantitative trait loci (QTL) analysis for large complex pedigrees. We apply a forward selection scheme to include several QTL and interaction effects, as well as polygenic effects, with up to five variance components in the model.

Efficient algorithms for multidimensional global optimization in genetic mapping of complex traits.

We present a two-phase strategy for optimizing a multidimensional, nonconvex function arising during genetic mapping of quantitative traits. Such traits are believed to be affected by multiple so called quantitative trait loci (QTL), and searching for d QTL results in a d-dimensional optimization problem with a large number of local optima. We combine the global algorithm DIRECT with a number of local optimization methods that accelerate the final convergence, and adapt the algorithms to problem-specific features.

[Ultrasound-induced myocardial preconditioning: analysis of its effectiveness and mechanisms].

It has been shown that exposure of the isolated rat heart perfused according to Langendorff to therapeutic ultrasound (210 kHz and 0.5-1.5 W/cm2 ) induces a cardioprotective response similar to ischemic preconditioning.
