In this paper, a new short hierarchical identity-based signature (HIBS) scheme is proposed in the standard model. This scheme has some advantages over the available schemes: the private keys size shrinks as the identity depth increases and the signature size is constant as it consists of three group elements. Furthermore, under the generalization selective-identity security model, we reduce the...

The ISCR elements ISCR3, ISCR4, ISCR5, ISCR14, and ISCR16 all share a percent G+C of 68 to 69%. They also share between 75% and 97% identity in their transposase open reading frames. Furthermore, with the exception of ISCR5, they are all found adjacent to sections of groEL that display the highest identity to the same gene from Xanthomonas spp. The combined information is consistent with the de...

In this article the author explains the social role of Muslim woman in a postmodern society through a public symbol of her identity--the veil. The article's thesis is that the Muslim women's manifestation of their Islamic denomination through veiling and wearing appropriate clothes (in the case of men through growing beards and wearing clothes considered appropriate for them) signifies an expre...

Bus rapid transit (BRT) is a flexible, high performance rapid transit mode that combines facilities, equipment, service and intelligent transportation system (ITS) elements into a permanently integrated system with a quality image and unique identity. Vehicles are an extremely important component of BRT systems, because they not only contribute significantly to BRT’s image and identity, but als...

An experiment with the nonassociative algebra program Albert led to the discovery of the following surprising theorem. Let G be a groupoid satisfying the identity (xy)z = y(zx). Then for products in G involving at least ve elements, all factors commute and associate. A corollary is that any semiprime ring satisfying this identity must be commutative and associative, generalizing a known result ...

A Boolean ring satisfies the identity x2 = x which, of course, implies the identity x2y − xy2 = 0. With this as motivation, we define a subBoolean ring to be a ring R which satisfies the condition that x2y−xy2 is nilpotent for certain elements x, y of R. We consider some conditions which imply that the subBoolean ring R is commutative or has a nil commutator ideal. Mathematics Subject Classific...

In his work on Wiener-Hopf determinants, A. Böttcher came across what he termed a “mysterious” identity that evaluates a certain sum of a rational function of a primitive root of unity in terms of the Barnes Gfunction, which was later generalized by Basor and Forrester. We give a direct proof of Böttcher’s identity and its many generalizations by using elements of the theory of symmetric functi...
