Some regions of the genomes of human B-lymphotrophic virus (HBLV), also designated as human herpesvirus 6, and Marek's disease virus were found to hybridize to each other under moderate to stringent conditions, scoring from 10 to 30% base-pair mismatch. Nucleotide sequence analysis showed that a 6-base-pair repetitive sequence, GGGTTA (DR2), present in the IRS-IRL junction region of the Marek's...

Ehrlichia risticii, the causative agent of Potomac horse fever, has recently been isolated from many vaccinated horses with typical clinical signs of the disease. The heterogeneity of the E. risticii isolates obtained from the vaccinated horses necessitates the identification of the molecular basis of strain variations to elucidate the vaccine failure and to aid in the development of an efficie...

Bacterial genome annotations are accumulating rapidly in the GenBank database and the use of automated annotation technologies to create these annotations has become the norm. However, these automated methods commonly result in a small, but significant percentage of genome annotation errors. To improve accuracy and reliability, we analyzed the Caulobacter crescentus NA1000 genome utilizing comp...

For the first time, a comparative analysis of thyroid cancer incidence in Ukraine after the Chernobyl accident was done in a cohort that is almost as large as the general population. On the basis of thyroid doses from radioactive iodine in individuals aged 1-18 years at the time of accident, geographic regions of Ukraine with low and high average accumulated thyroid doses were established and d...

Census Designated Places (CDPs) are the Rodney Dangerfields of urban geography— they get no respect. The public does not understand them and researchers often overlook CDPs because they are seen as census-derived statistical artifacts as opposed to “real” places. Yet a CDP is a residential concentration whose population sees itself as belonging to a specific place, even if the place is not an o...

This paper proposes a designated verifier signature scheme based on the Schnorr signature and the Zheng signcryption schemes. One of the advantages of the new scheme compared with all previously proposed schemes is that it achieves the “strong designated verifier” property without encrypting any part of the signatures. This is because the designated verifier’s secret key is involved in the veri...

Universal Designated-Verifier Signatures (UDVS) are proposed to protect the privacy of a signature holder. Since UDVS schemes reduce to standard signatures when no verifier designation is performed, from the perspective of a signer, it is natural to ask if a UDVS can be constructed from widely used standardized-signatures so that the existing public key infrastructures for these schemes can be ...

Ring signatures enable a user to sign a message so that a ring of possible signers is identified, without revealing exactly which member of that ring actually generated the signature. In some situations, however, an actual signer may possibly want to expose himself, for instance, if doing so, he will acquire an enormous benefit. In this paper, we present a Schnorr ring signature scheme with des...

Designated verifier signature schemes are applied in situations such as electronic voting and electronic auctions. Signature recipients can ascertain the contents of the document, but cannot verify the identity of the signer to a third party. This study reviewed the protocols of past researches and analyzed whether these protocols would disclose signer identities under various types of attacks....

The letters on the left of the sequence designate the species origin (R=rat, H=human). The deduced amino acid sequence is shown in single letter code. Putative transmembrane spanning regions are delineated by a dotted line and labeled Ml to M4. Peptide sequences determined from purified rat synaptophysin are underlined and designated PI to P4. The 15 positions where there are differences betwee...
