An attribute-based signature (ABS), is a cryptographic scheme where someone can sign message using any kind of predicates verified by the attributes he owns. For such scheme, it expected to be impossible for users collude if none them originally able on his own. The main advantage solution that signer remain anonymous in set fulfilling chosen predicate. It then used authentication instance. In ...

It was shown recently that the genus Burkholderia is rich in N2-fixing bacteria that are associated with plants. A group of these diazotrophic isolates with identical or very similar 16S rDNA restriction patterns [designated amplified rDNA restriction analysis (ARDRA) genotypes 13, 14 and 15] was selected and a polyphasic taxonomic study was performed, which included new isolates that were reco...

Taxa in the Gyromitra gigas species complex were previously studied and their taxonomy resolved. During ongoing studies this group, cryptic speciation was discovered G. gigas. Sequences of ITS LSU regions from 75 specimens included maximum likelihood Bayesian phylogenetic analyses to establish boundaries resolve relationships. Sequence similarity comparisons also conducted between two ribosomal...

The notion of strong designated verifier signature was put forth by Jakobsson, Sako and Impagliazzo in 1996, but the formal definition was defined recently by Saeednia, Kremer and Markowitch in 2003 and revisited by Laguillaumie and Vergnaud in 2004. In this paper, we firstly propose the notion of short strong designated verifier signature scheme, and extend it to the short identity-based stron...

FORT WASHINGTON, PA — On January 31, 2015, the National Comprehensive Cancer Network ® (NCCN ® ) celebrates its 20 th anniversary. Originally announced as an alliance of 13 leading cancer centers in 1995, NCCN has grown to a network of 25 academic cancer centers; the NCCN mission as an alliance of leading academic cancer centers devoted to patient care, research, and education, is to improve th...

Inherited mutations in BRCA1 confer susceptibility to breast and ovarian neoplasms. However, the function of BRCA1 and the role of BRCA1 in noninherited cancer remain unknown. Characterization of alternately spliced forms of BRCA1 may identify functional regions; thus, we constructed expression vectors of BRCA1 and a splice variant lacking exon 11, designated BRCA1 delta 672-4095. Immunofluores...

the effects of magnesium hydroxide and l-lactide dimer as additives on thermal properties and morphology of poly(l-lactide) (plla) films were studied. hence, neat plla films and films containing additives (10% w/w) were prepared in dichloromethane at room temperature via solution casting. to evaluate thermal history on polymer properties, plla films were annealed by different processes. in one ...
