Classification of Hungarian medieval silver coins using x-ray fluorescent spectroscopy and multivariate data analysis

Background: A set of silver coins from the collection of Déri Museum Debrecen (Hungary) was examined by X-ray fluorescent elemental analysis with the aim to assign the coins to different groups with the best possible precision based on the acquired chemical information and to build models, which arrange the coins according to their historical periods. Results: Principal component analysis, line...

Moving coins

We consider combinatorial and computational issues that are related to the problem of moving coins from one configuration to another. Coins are defined as non-overlapping discs, and moves are defined as collision free translations, all in the Euclidean plane. We obtain combinatorial bounds on the number of moves that are necessary and/or sufficient to move coins from one configuration to anothe...

Detachable Electronic Coins

We propose a non-divisible electronic cash system that combines the restrictive blind signature technique and a batch signature scheme based upon the binary tree structure. Contemporary electronic cash solutions rely on the divisibility paradigm to achieve significant computational savings, and such techniques are considered to be the most efficient. We demonstrate an alternative approach that ...

Private Coins versus Public Coins in Zero-Knowledge Proof Systems

Goldreich-Krawczyk (Siam J of Comp’96) showed that only languages in BPP have constant-round public-coin black-box zero-knowledge protocols. We extend their lower bound to “fully black-box” privatecoin protocols based on one-way functions. More precisely, we show that only languages in BPP—where Sam is a “collision-finding” oracle in analogy with Simon (Eurocrypt’98) and Haitner et. al (FOCS’07...

When Brains Flip Coins

In a recent study in the journal Cell, Tervo et al. (2014) show that animals can implement stochastic choice policies in environments unfavorable to predictive strategies. The shift toward stochastic behavior was driven by noradrenergic signaling in the anterior cingulate cortex.
