Abstract: Symbol-pair codes are proposed to protect against pair errors in symbol-pair read channels. One of the most important task in symbol-pair coding theory is to determine the minimum pair-distance of symbol-pair codes. In this paper, we investigate the symbol-pair distances of cyclic codes of length p over Fpm . The exact symbol-pair distances of all cyclic codes of such length are deter...

The emphasis of economic development practitioners and researchers is on modern determinants of per capita income such as quality of institutions to support markets, economic policies chosen by governments, human capital components such as education and health, or political factors such as violence and instability. Could this discussion be missing an important, much more long-run dimension to e...

It has been suggested that birds prefer to use a particular eye while learning to detect cryptic prey and that this eye preference enhances foraging performance. European starlings (Sturnus vulgaris) with the left, right, or both eyes available learned to detect inconspicuous cues associated with the presence of hidden prey. Acquisition scores were not significantly different between left and r...

The black-eyed gecko (Hoplodactylus kahutarae Whitaker 1984), of eastern Marlborough, is arguably NZ's only alpine lizard, inhabiting cliffs and bluffs between 1,250 and 2,200 m asl. In January 1998 a black-eyed gecko was discovered at Eyles Creek on Mt Arthur, Kahurangi National Park, 120 km northwest of its previously known range. A follow up survey in March revealed that population density a...

We evaluated the relationship between Red-eyed Vireo (Vireo olivaceus) abundance and foliage density and forest structurein a northern hardwood forest on Douglas Lake, Michigan. We found no relationship between the abundance of Red-eyed Vireos and forest structure complexity. Although our results suggest that Red-eyed Vireo density does not increase with forest structure, as predicted, our samp...

To test whether there is a relationship between handedness and the intraocular pressure and there is a lateralization in the intraocular pressure, the intraocular pressures of the right- and left-eyes were compared in right- and left-handed students. The intraocular pressures were higher in the right-eye than in the left-eye in men, right-handers, and right-eyed subjects; there was no right-lef...

The pigmentation of black (wild) and red (mutant) eyes of Triatoma infestans was studied spectrophotometrically and compared with red-eyed (wild) and white-eyed (mutant) forms of Drosophila melanogaster. The spectral absorption profiles of the black and red eye pigments of T. infestans were similar to each other and to that of the wild-type eyes of D. melanogaster. The similarity to the wild fo...
