<p><span>The researchers have been exploring methods to use biometric characteristics of the user as a replacement for using unforgettable pass-word, in an attempt build robust cryptographic keys, because, human users detect difficulties call up long keys. Biometric recognition provides authentic solution authentication problem identity administration systems. With extensive utiliza...

This study attempted to replicate a recent finding by Crow et al. [Neuropsychologia 36 (1998) 1275] showing that about equal skill of right and left hand (i.e. hemispheric indecision) is associated with deficits in cognitive and scholastic achievement. The present study assessed hemispheric indecision by using Annett's [Left, Right, Hand and Brain: The Right Shift Theory, Lawrence Erlbaum, Lond...

Karyotypes were studied in the hooded and carrion crows, their naturally occurred hybrids, the jungle crow, the azure-winged magpie (2n = 80 in all aforementioned birds), and the magpie (2n = 82). Corvine birds of Primorskii Krai were karyotyped for the first time. In addition to the similarity in the diploid chromosome sets, corvine birds were shown to have a similar structure of karyotype: in...

The Hooded Crow (Corvus cornix) is often considered the main nest predator of many bird species, especially waterbirds. Such relationship should be particularly clear during the breeding season in wetlands, when the need to supply their nestlings with the highest quality foods forces predators to intensify their hunting activities. Hence, waterbirds should be their basic prey. We examined the c...

We use the coupling matrix formalism to investigate continuous wave and pulse propagation through microring coupled-resonator optical waveguides (CROWs). The dispersion relation agrees with that derived using the tight-binding model in the limit of weak inter-resonator coupling. We obtain an analytical expression for pulse propagation through a semi-infinite CROW in the case of weak coupling wh...

Before 1900, Blacks typically occupied the swampy portions of New Orleans, Louisiana. As the city embarked on an ambitious Progressive Era public works project to improve drainage in the 1890s, it began to overhaul environmental conditions. This process, if carried out according to rational engineering principles, would serve the entire city equitably. At the same time as the improvements, Jim ...
