In this article we investigate the universal C∗-algebras associated to certain 1dimensional simplicial flag complexes which describe the noncommutative circle. We denote it by S 1 . We examine the K-theory of this algebra and the subalgebras S nc 1 /Ik, Ik . Where Ik, for each k, is the ideal in S 1 generated by all products of generators hs containing at least k + 1 pairwise different generato...

Abstract. We discuss the Cucker-Smale’s (C-S) particle model for flocking, deriving precise conditions for flocking to occur when pairwise interactions are sufficiently strong long range. We then derive a Vlasov-type kinetic model for the C-S particle model and prove it exhibits time-asymptotic flocking behavior for arbitrary compactly supported initial data. Finally, we introduce a hydrodynami...

one concern about using transgenic plants is the genetic variation that occurred from theirs tissue culture and regeneration. molecular markers are an important element for efficient and effective determination of genetic variation. the present work was carried out to assess the genetic uniformity of transgenic cottons (bt and chitinase lines), using rapd, issr molecular markers and sds-page an...

Let |h| 3 ∅. In [50], the authors characterized algebras. We show that there exists an almost everywhere sub-ordered, pseudo-normal, pairwise contravariant and maximal subalgebra. Therefore a useful survey of the subject can be found in [50]. It would be interesting to apply the techniques of [35, 34] to composite categories.

In this paper, using the exact expression for the pairwise error probability derived in terms of the message symbol distance between two message vectors rather than the codeword symbol distance between two transmitted codeword matrices, the exact closed form expressions for the symbol error probability of any linear orthogonal space-time block codes in slow Rayleigh fading channel are derived f...

Abstract — For a space-time coded system in a correlated Rayleigh fading environment, we consider two receiver structures: (1) a suboptimum one in which the imperfect channel state information (CSI) is used in place of perfect CSI in a perfect CSI optimum receiver, (2) the optimum receiver in which the imperfect CSI is used in the maximum likelihood sense. Channel estimation is done by the use ...

The research presented is a partial empirical evaluation of the second author’s proposed psychophysical theory (Luce, 2002, 2003a,b). The theory deals with the global percept of subjective intensity in which there is a psychophysical function Ψ that maps pairs of physical intensities onto the positive real numbers and represents subjective summation and a form of ratio production. A number of b...
