Different Levels

ABSTRACTThe symmetry conditions which rule the matching of a fulleren molecule's main axis in a translational lattice are considered. The full set of orientational states for the structure of fullerene are obtained. The different levels of correlations between symmetry axes of icosahedral molecule and cubic lattice are considered. This result used for analysis of orientational ordering models, including modulation structure and discrete orientational glass.

The significant matter for the construction of the so-called no-boundary proposal is the assumption of signature transition, which has been a way to deal with the problem of initial conditions of the universe. On the other hand, results of Loop Quantum Gravity indicate that the signature change is related to the discrete nature of space at the Planck scale. Motivated by possibility of non-Archimedean and/or noncommutative structure of space–time at the Planck scale, in this work we consider the classical, p-adic and (spatial) noncommutative form of a cosmological model with Friedmann–Robertson–Walker (FRW) metric coupled with a self-interacting scalar field.

Discrete Nature

The article provides information about the stress state protective and decorative coatings during aging. The influence of the discrete nature of the substrate on the change in the stress state of the coatings from the action of the wind load is considered. It was revealed that for each type of coating there is its own critical value of the pore size (unfilled paint), the excess of which leads to cracking of the coatings. A method is proposed for selecting the optimal coating thickness.

Examination of polynucleotide sequence relationships among 11 strains of Vibrio anguillarum biotype 2 isolated from moribund fish in North America and Japan demonstrated the highly conserved character of this group of fish pathogens and, moreover, confirmed its discrete nature from V. anguillarum biotype 1. Additional molecular analyses of the V. anguillarum biotype 2 strains revealed the universal presence of a multicopy plasmid with a molecular mass of approximately 20 × 106 daltons and a mole percent guanine plus cytosine of 44. The plasmid of strain DF3K was representative of this molecular species and was designated pMJ101. Subsequent DNA–DNA hybridizations using nick translation-labeled pMJ101 as a probe indicated all the 20 × 106 dalton plasmids were either identical or highly conserved, and, furthermore, that pMJ101 was apparently unrelated to either the virulence plasmid, pJM1, of V. anguillarum biotype 1 or to representatives of common plasmid incompatibility groups. The lack of relatedness between pMJ101 and pJM1 was further supported by differences in their restriction endonuclease cleavage patterns.
