We isolated a novel gene by a differential-display RT-PCR method comparing basal disk tissue and peduncle tissue in a species of Hydra, Pelmatohydra robusta, and we referred to it as anklet. The putative anklet product has a signal sequence in its N-terminus, and it has one MAC/PF domain and one EGF domain. In normal hydra, the expression of anklet was restricted in the periphery of the basal d...

BACKGROUND AND PURPOSE DTI can provide information about brain ultrastructure by quantifying water diffusion. Our objective was to assess the value of DTI in detecting the acute effects of alcohol on healthy human brains. MATERIALS AND METHODS Sixteen healthy volunteers were studied with conventional MR imaging and DTI before and 0.5, 1, 2, and 3 hours after the initiation of acute alcohol ad...

In this Letter we discuss the entanglement near a quantum phase transition by analyzing the properties of the concurrence for a class of exactly solvable models in one dimension. Entanglement can be classified in the framework of the scaling theory of phase transitions. There is a profound differences between the classical correlations, whose correlation lenght diverges at the phase transition,...

Chinese is a tone language. As a tone language, each lexical item has an inherent tone pattern. In Chinese there are four tones : high, rising, low and falling. Our experiment investigates first the pattern of declination in Standard Chinese broadcasts and TV news speech, secondly the interaction of this effect with the sentence lenght and finally the evolution of the tones F0 values all throug...

We formulate the Hopf algebra underlying the su(2|2) S-matrix relevant for the AdS/CFT correspondence, extending the one discovered by Janik in the su(1|2) sector to the full algebra, by specifying the action of the coproduct and the antipode on the remaining generators. The nontriviality of the coproduct is determined by the lenght-changing effect, and results in an unusual central braiding. W...

in this paper, static performance characteristics for a finite lenght two-lobe journal bearing lubricated with micropolar fluid is studied. using finite element method, steady-state film pressure is obtained by solving modified reynolds equation, based on micropolar lubrication theory. with the help of film pressure in bearing, the static performance characteristics in terms of load carrying ca...

to identify the high yielding lines with optimal characteristics, 40 recombinant inbred lines derived from a cross between ‘norstar’ (winter wheat) and ‘zagros’ (spring wheat) cultivars were examined using a randomized complete block design with three replications in 2014 at the research station of faculty of agriculture, university of tabriz, iran. the measured characters consisted of peduncle...

Kernel weight is an important factor determining grain yield and nutritional quality in sorghum, yet the developmental processes underlying the genotypic differences in potential kernel weight remain unclear. The aim of this study was to determine the stage in development at which genetic effects on potential kernel weight were realized, and to investigate the developmental mechanisms by which ...
