Identity, in the context of our communal online space, is a fungible concept. Who we are, how we represent ourselves, how we’re identified, how we’re verified, and how we’re investigated all are critical components of the larger notion of online identity. To that extent, the field is truly multi-faceted; cryptographers and computer scientists debate procedures of verification and authentication...

Let A be an abelian group with non-identity elements A∗. A graph is A-magic if it has an edge-labeling by elements of A∗ which induces a constant vertex labeling of the graph. In this paper we determine, for certain classes of triominoes and polyominoes, for which values of k ≥ 2 the graphs are Zk-magic.

Mutations of the segment polarity group in Drosophila melanogaster produce additional denticles with reversed polarity in every segment of the larval cuticle. We have investigated the effect of mutations in different elements of the bithorax complex on the segmental identity of these additional pattern elements. Our results suggest that they are derived, primarily, from the anterior compartment...

We have investigated the distribution of sequences homologous to Bari-1, a Tc1-like transposable element first identified in Drosophila melanogaster, in 87 species of the Drosophila genus. We have also isolated and sequenced Bari-1 homologues from D. simulans, D. mauritiana, and D. sechellia, the species constituting with D. melanogaster the melanogaster complex, and from D. diplacantha and D. ...

The concept of “identity” of a complex network system is proposed based on the method of the gauge field theory. The system is assumed to consist of many elements interacting with each other. The interaction weight is treated as a gauge potential. Change in the external environment surrounding the system is assumed to induce a unitary transformation of the state vector of the system, which is r...

We present a novel approach to e-voting for elections, based on a new cryptographic construction, double-blind identity based encryption (IBE). In standard IBE, the identity string that is passed to a key generation centre (KGC) during the key extraction phase is visible to the KGC. Recent work introduced the notion of blinding the identity string, resulting in a private key generation protocol...

We have identified 141 novel palindromic repetitive elements in the genome of euryarchaeon Methanocaldococcus jannaschii. The total length of these elements is 14.3kb, which corresponds to 0.9% of the total genomic sequence and 6.3% of all extragenic regions. The elements can be divided into three groups (MJRE1-3) based on the sequence similarity. The low sequence identity within each of the gr...
