During embryonic morpho-genesis, a collection of individual neurons turns into a functioning network with unique capabilities. Only recently has this most staggering example of emergent process in the natural world, began to be studied. Here we propose a navigational strategy for neurites growth cones, based on sophisticated chemical signaling. We further propose that the embryonic environment ...

Graphene exhibits unique electronic properties, and its low dimensionality, structural robustness, and high work-function make it very promising as the charge storage media for memory applications. Along with the development of miniaturized and scaled up devices, nanostructured graphene emerges as an ideal material candidate. Here we proposed a novel non-volatile charge trapping memory utilizin...

Storytelling is an activity of intelligent play generated by humans for the benefit of humans. Qualities of intelligent play reflect the intentions, processes and tools that are available to humans for the purpose of story construction. Personal media collections speak to intention. They als serve as a tool to help us better communicate who we are and who we would like to become. Augmented by c...

The Utiscreen-CORAL Biomedical system and ROBOBACT system were tested against conventional uroculture in blood agar and MacConkey agar as a reference method to determine the bacteriuria from 400 samples. For the Utiscreen-CORAL Biomedical system, a sensitivity of 92.5% was obtained. However, by the ROBOBACT system, the sensitivity was 69.9%.

We present new results on the structure of the solar core, obtained with new sets of frequencies of solar low-degree p modes obtained from the BiSON network. We find that different methods used in extracting the different sets of frequencies cause shifts in frequencies, but the shifts are not large enough to affect solar structure results. We find that the BiSON frequencies show that the solar ...

We study propagation failure using the one-dimensional scalar bistable equation with a passive “gap” region. By applying comparison principles for this type of equation, the problem of finding conditions for block is reduced to finding conditions for the existence of steady state solutions. We present a geometrical method that allows one to easily compute the critical gap length above which a s...

We examine the gravitational redshift of radiation emitted from within the potential of a cluster. Spectral lines from the intracluster medium (ICM) are redshifted in proportion to the emission-weighted mean potential along the line of sight, amounting to approximately 50 km s-1 at a radius of 100 kpc h-1, for a cluster dispersion of 1200 km s-1. We show that the relative redshifts of different...

A 5×5 board is the smallest board on which one can set up all kind of chess pieces as a start position. We consider Gardner’s minichess variant in which all pieces are set as in a standard chessboard (from Rook to King). This game has roughly 9 × 10 legal positions and is comparable in this respect with checkers. We weakly solve this game, that is we prove its game-theoretic value and give a st...
