OBJECTIVE To investigate differences in tongue images of subjects with and without hyperuricemia. MATERIALS AND METHODS This population-based case-control study was performed in 2012-2013. We collected data from 46 case subjects with hyperuricemia and 46 control subjects, including results of biochemical examinations and tongue images. Symmetrical Haar-like features based on integral images w...

During tension of samples low-carbon steels and some other plastic materials, the sharp yield point plateau are fixed on deformation diagram. In this case, Chernov-Luders bands appear surface sample in local section, which then propagate along axis. The physical nature is established: drop load after reaching (upper) limit occurs as a result dislocations being an extraction out cloud embedded a...

A general expression for the correlation time of the decay of the magnetization of an assembly of singledomain noninteracting ferromagnetic particles is given in terms of the inverse of the Fokker-Planck operator. The results of Moro and Nordio @G. Moro and P. L. Nordio, Mol. Phys. 56, 255 ~1985!#, given in the context of dielectric relaxation, are recovered when the Fokker-Planck operator is a...

in this paper, an iterative scheme for extracting approximate solutions of two dimensional volterra-fredholm integral equations is proposed. considering some conditions on the kernel of the integral equation obtained by discretization of the integral equation, the convergence of the approximate solution to the exact solution is investigated. several examples are provided to demonstrate the effc...

This paper studies the existence of positive solutions for a class of second-order semipositone differential equations with a negatively perturbed term and integral boundary conditions. By using a well-known fixed-point index theorem, some new existence results are derived for the case where nonlinearity is allowed to be sign changing. Several examples are presented to demonstrate the applicati...
