Twister quintessence scenario

Correlated Isocurvature Fluctuation of Quintessence and Curvaton Scenario

We consider cosmic microwave background (CMB) anisotropy in models with quintessence taking into account of isocurvature fluctuation in the quintessence. It is shown that, if the primordial fluctuation of the quintessence has a correlation with the adiabatic density fluctuations, CMB angular power spectrum Cl at low multipoles can be suppressed. Possible scenario of generating correlated mixtur...

Cryptanalysis of Twister

In this paper, we present a pseudo-collision attack on the compression function of all Twister variants (224,256,384,512) with complexity of about 2 compression function evaluations. Furthermore, we show how the compression function attack can be extended to construct collisions for Twister-512 with complexity of about 2. 1 Description of Twister The hash function Twister is an iterated hash fu...

twister - a P2P microblogging platform

This paper proposes a new microblogging architecture based on peerto-peer networks overlays. The proposed platform is comprised of three mostly independent overlay networks. The first provides distributed user registration and authentication and is based on the Bitcoin protocol. The second one is a Distributed Hash Table (DHT) overlay network providing key/value storage for user resources and t...

This case report looks at a case of traumatic avulsion and subsequent apexification of a maxillary permanent incisor of a 6-year-old boy and a 10-year follow-up is reported. Treatment included apexification of the tooth with incomplete root formation using mineral trioxide aggregate and restoration of the immature root with a zirconia post and a coronal composite restoration. At the 10-year fol...
