Exploiting QBF Duality on a Circuit Representation
Search based solvers for Quantified Boolean Formulas (QBF) have adapted the SAT solver techniques of unit propagation and clause learning to prune falsifying assignments. The tech...

Uplink-Downlink Duality of ICI Cancellation in OFDMA Systems with Carrier-Frequency Offset
— In orthogonal frequency-division multiplex access (OFDMA) systems, including uplink and downlink, the carrierfrequency offset (CFO) between the multiple transceivers introduces...

Blind separation of non-negative sources by convex analysis: Effective method using linear programming
We recently reported a criterion for blind separation of non-negative sources, using a new concept called convex analysis for mixtures of non-negative sources (CAMNS). Under some ...

An Effective Branch-and-Bound Algorithm for Convex Quadratic Integer Programming
We present a branch-and-bound algorithm for minimizing a convex quadratic objective function over integer variables subject to convex constraints. In a given node of the enumerati...

On the unity of duality
Most type systems are agnostic regarding the evaluation strategy for the underlying languages, with the value restriction for ML which is absent in Haskell as a notable exception....
