The evolution of texture was discussed during the formation of ultra-fine and nano grains in a magnesium alloy severely deformed through accumulative back extrusion (ABE). The microstructure and texture obtained after applying multiple deformation passes at temperatures of 100 and 250°C were characterized. The results showed that after single ABE pass at 100°C an ultrafine/nano grained microstr...

Bilinear groups are often used to create Attribute-Based Encryption (ABE) algorithms. In particular, they have been used to create an ABE system with multi authorities, but limited to the ciphertext-policy instance. Here, for the first time, we propose two multi-authority key-policy ABE systems. In our first proposal, the authorities may be set up in any moment and without any coordination. A p...

The audiovisual bounce inducing effect (ABE) is a bouncing percept induced by the presentation of a sound in a motion display otherwise perceived as streaming. The literature suggests that the origin of the ABE is double: the effect stems from the action of an attentional component and that of a non-attentional component. However, the type of response classically gathered in ABE studies does n...

Personal Health Record (PHR) is a web based set of tools that provides the facility to exchange and maintain a complete electronic health record of a patient. Third-party service providers are available to maintain PHRs like HealthVault1, Google Health or Web MD. These applications allow individuals to enter, store and share their own health data, upload health measurements from their devices o...

Aim: W1282X is the sixth most common cystic fibrosis (CF)-causing variant and one of those without an approved therapy. Adenine base editing (ABE) has attracted interest as it can correct mutations creating a double-stranded break in DNA, being thus potentially safer than traditional approach with CRISPR/Cas9. Efficient correction by ABE been reported but bystander edits have observed at adjace...

Attributes based encryption (ABE) can achieve flexible and scalable access control and gurantee the confidentiality of the data stored in the cloud. However, important issues such as efficient user revocation and fine-grained access control are not straightforward, which constrain the adoption of ABE in cloud storage systems.Our proposed scheme realizes fine-grained read and write access contro...

The present study was designed to investigate the effect of Agaricus brasiliensis extract (ABE) on phenylhydrazine-induced neonatal jaundice in rats. Administration of ABE dose-dependently reduced the elevated bilirubin level induced by phenylhydrazine. It can be somewhat supported from the results of in vitro bilirubin degradation experiment. ABE treatment also reduced the total antioxidant st...

The concept of partially blind signatures was first introduced by Abe and Fujisaki. Subsequently, in work by Abe and Okamoto, a provably secure construction was proposed along with a formalised definition for partially blind schemes. The construction was based on a witness indistinguishable protocol described by Cramer et al. and utilises a blind Schnorr signature scheme. This paper investigate...

We propose the first Key-policy Attribute-based Encryption (KP-ABE) scheme for (monotone) Boolean circuits based on bilinear maps. The construction is based on secret sharing and just one bilinear map, and can be viewed as an extension of the KP-ABE scheme in [7]. Selective security of the proposed scheme in the standard model is proved, and comparisons with the scheme in [5] based on leveled m...

We present a modular framework for the design of efficient adaptively secure attribute-based encryption(ABE) schemes for a large class of predicates under the standard k-Lin assumption in prime-order groups; this is thefirst uniform treatment of dual system ABE across different predicates and across both composite and prime-ordergroups. Via this framework, we obtain concrete efficie...
