Attribute-based encryption with non-monotonic access structures
We construct an Attribute-Based Encryption (ABE) scheme that allows a user’s private key to be expressed in terms of any access formula over attributes. Previous ABE schemes wer...

Polynomial Preconditioning for Specially Structured Linear Systems of Equations
For the solution of the SID (Symmetric InDefinite) linear systems, the use of the GLS (Generalized Least-Squares) polynomial preconditioner can improve the execution efficiency of...

Detecting chaotic structures in noisy pulse trains based on interspike interval reconstruction
The nonlinear prediction method based on the interspike interval (ISI) reconstruction is applied to the ISI sequence of noisy pulse trains and the detection of the deterministic st...
