Accountable ring signature (ARS), introduced by Xu and Yung (CARDIS 2004), combines many useful properties of ring and group signatures. In particular, the signer in an ARS scheme has the flexibility of choosing an ad hoc ...

We reexamine generation of the primordial magnetic fields, at temperature T>80 TeV, by applying a consistent kinetic theory framework which is suitably modified to take the quantum anomaly into account. The modified kinetic ...
