We introduce the notation of organizational signature. This is a new variant of digital signature, which allows the organization to obtain the signature of any employee not as an individual but through his affiliation. Due to this signature, an organization, e.g. company, can create different signatures related to each position. Elliptic curves discrete logarithm problem (ECDLP) has a low compu...

In this work, we consider a scenario that includes an individual sharing his genomic data (or results obtained from his genomic data) with a service provider. In this scenario, (i) the service provider wants to make sure that received genomic data (or results) in fact belongs to the corresponding individual (and computed correctly), (ii) the individual wants to provide a digital consent along w...

The new Italian cytological classification (2014) of thyroid nodules replaced the TIR3 category of the old classification (2007) with two subclasses, TIR3A and TIR3B, with the aim of reducing the rate of surgery for benign diseases. Moreover, thyroid imaging reporting and data system (TI-RADS) score appears to ameliorate the stratification of the malignancy risk. We evaluated whether the new It...

The objective of this study was to evaluate the effect of titanium immobilized with a cationic antimicrobial peptide (JH8194) derived from histatin on the biofilm formation of Porphyromonas gingivalis and differentiation of osteoblastic cells (MC3T3-E1). The titanium specimens (Ti) were immobilized with JH8194, according to the method previously described. The colonization of P. gingivalis on J...

This paper proposes a group signature scheme with efficient membership revocation. Though group signature schemes with efficient membership revocation based on a dynamic accumulator were proposed, the previous schemes force a member to change his secret key whenever he makes a signature. Furthermore, for the modification, the member has to obtain a public membership information of O( nN) bits, ...

Proxy signatures are very useful tools when one needs to delegate his/her signing capability to other party. After Mambo et al.’s first scheme was announced, many proxy signature schemes and various types of proxy signature schemes have been proposed. Due to the various applications of the bilinear pairings in cryptography, there are many IDbased signature schemes have been proposed. In this pa...

In the late 1670’s to early 1680’s, Leibniz came to hold that the laws of nature are paradigmatically contingent, that they provide the basis for a new argument from design, and that they presuppose the existence of active, goal-directed powers reminiscent of Aristotelian entelechies. In this essay, I argue that the standard view according to which Leibniz forges these signature theses in the d...

The idea of a proxy signature scheme was first presented by Mambo et al. [1] in 1996. Their proxy signature scheme allows an original signer to delegate his signing right to a proxy signer to sign the message on behalf of an original signer. Later, the verifier, which knows the public keys of original signer and a proxy signer can check a validity of a proxy signature issued by a proxy signer. ...

the center of the San Joaquin Valley, on January 24, 1875. He had asthma as a child and spent much of his time drawing. In 1891, when he was 16, Dixon sent two of his sketchbooks to Frederic Remington, an artist he admired. Remington encouraged him, replying, “You draw better at your age than I did at the same age. If you have the ‘sand’ to overcome difficulties, you could be an artist in time....
