The literature is replete with reports of foreign bodies found in the upper urinary tract. However, most have necessitated removal by open surgery or percutaneous nephrostomy. We describe a nonoperative removal of a foreign body from a kidney.
In this paper, we present a new class of graphs named quasi-locally paw-free (QLP) graphs. We prove the strong perfect graph conjecture for a subclass of Ghd Sale Auckland QLP class, by exhibiting a polynomial combinatorial algorithm for ω-coloring any Berge graph Ghd Online Registration
for this subclass. This subclass contains K4-free graphs and chordal graphs.
Two recent extensions of the coupled mode theory to non-parallel waveguide systems are examine here, qualitatively and numerically. It is shown that whereas the basic formulation, when applied to non-parallel systems, is reasonable for describing coupling between nearly parallel waveguides, these two extended formulations may be incompatible for non-parallel guides, on physical grounds.
The S-transform is an extension of the continuous wavelet transform (CWT) and is based on a moving and scalable localizing Gaussian window. The interference fringes are analyzed for the determination of optical 3-D surface profile by using S-transform and continuous wavelet transform algorithms. It is seen that the S-transform gave a better 3-D profile than other method and showed a higher frequency resolution.
