An overview is given of the attempts to understand the behavior of scroll waves in threedimensional excitable media using analytical methods, and these results are compared with recent numerical and experimental results. The behavior of untwisted planar scroll rings, twisted rings and helices, and knotted scroll wave filaments is discussed.

This work studies both theoretically and experimentally the formation of the contour interference patterns generated by a two-wavelength real-time holographic interferometer. The resulting contour interference fringes are due to the intersection of the measured surface with parallel, equally spaced planes of constant elevation. The theoretical analysis describes how the spatial frequency of the...

The understanding of metal nucleation on graphene is essential for promising future applications, especially of magnetic metals which can be used in spintronics or computer storage media. A common method to study the grown morphology is to measure the nucleated island density n as a function of growth parameters. Surprisingly, the growth of Fe on graphene is found to be unusual because it does ...

In this paper, we investigate a design of biological excitable media based on non-excitable cells and intercellular calcium signaling mechanisms. The calcium induced calcium release mechanism in non-excitable cells is exploited to transform the non-excitable cells into excitable media that propagate calcium signals cell-to-cell. The biological excitable media investigated in this paper represen...

Polar dielectrics are being actively investigated as a promising platform for mid-infrared nanophotonics, and it indicates dramatic nonlocal phenomena at the nanoscale. Based on full-wave extended Mie theory, we analytically derive equivalent permittivity of polar dielectric nanospheres. Then, establish conditions surface phonon amplification by stimulated emission radiation core-gain shell nan...

A cross-sectional study was carried out from November 2016 to May 2017 isolate and identify Clostridium tetani. total of 71 samples (equine deep wound swabs, feces, soil the feces contaminated environment) were collected. Isolation tetani using an anaerobic Viande et Foie (VF) medium. Out cultured on VF medium, 27 (38%) them grown all confirmed be spore staining biochemical tests. Study site sa...
