Using highly accurate ab initio molecular dynamic simulations we calculate elastic constants of Ti0.5Al0.5N as a function temperature up to 1500 K and compare the results with those obtained for TiN. We analyze variation material’s anisotropy by calculating directional Young’s moduli Poisson ratios on (100), (110) (111) crystallographic planes. show that though strongly decrease upon heating, i...

in this paper, a new analytical approach has been presented for solving strongly nonlinear oscillator problems. iteration perturbation method leads us to high accurate solution. two different high nonlinear examples are also presented to show the application and accuracy of the presented method. the results are compared with analytical methods and with the numerical solution using runge-kutta m...

Objective: To study the protective effect of polyprenols on acute liver injury induced by CCl4 and D-Gal. Method: The acute liver injury model induced by 0.5% CCl4 in olive oil (10ml/kg) and D-Gal (800mg/kg, i.p.) in mice and rats respectively. 10, 40 and 160 mg/kg polyprenols was administered i.g., to study the protective effect for different doses of polyprenols, the therapeutic effect of eac...

A fast and accurate algorithm for the computation of eeective electric and mathematically equivalent properties of composites with non-smooth interfaces is reported. The algorithm is based on an integral equation reformu-lation of the electrostatic partial diierential equation and a fast hierarchical technique for potential eld evaluation. In a numerical example, two hundred large and strongly ...

BACKGROUND Bovine tuberculosis (bTB) is an enduring contagious disease of cattle that has caused substantial losses to the global livestock industry. Despite large-scale eradication efforts, bTB continues to persist. Current bTB tests rely on the measurement of immune responses in vivo (skin tests), and in vitro (bovine interferon-γ release assay). Recent developments are characterized by inter...

In this paper, we introduce a modified collaborative filtering (MCF) algorithm, which has remarkably higher accuracy than the standard collaborative filtering. In the MCF, instead of the cosine similarity index, the user-user correlations are obtained by a diffusion process. Furthermore, by considering the second-order correlations, we design an effective algorithm that depresses the influence ...

Methylation of cytosine in DNA is an epigenetic mark that is important for genome stability, transcriptional regulation of endogenous genes, and permanent silencing of transposable elements and viral sequences. Methylcytosine, sometimes referred to as the 5th base of DNA, constitutes 3%–6% of all cytosines in the human genome and occurs almost exclusively within the context of CpG dinucleotides...

MOTIVATION High-throughput sequencing technologies produce very large amounts of data and sequencing errors constitute one of the major problems in analyzing such data. Current algorithms for correcting these errors are not very accurate and do not automatically adapt to the given data. RESULTS We present HiTEC, an algorithm that provides a highly accurate, robust and fully automated method t...
