Auctions have been developed for economic transactions with asymmetric information and they are the simplest means of price determination for multilateral trading without ‘market makers.’ During the last years, new technologies gave a boost to the development and usage of innovative auction formats in several fields. We explore some of the new possibilities of applications and explain the diffe...

By means of the theory of majorization and under the proper hypotheses, the following inequalities of Jensen-Pečarić-Svrtan-Fan (Abbreviated as J-P-S-F) type are established: f (A(x)) g(A(x)) · · · fk+1,n(x) gk+1,n(x) fk,n(x) gk,n(x) · · · A( f (x)) A(g(x)) , where fk,n(x) := 1 (k) ∑ 1 i1<···<ik n f ( xi1 + · · ·+ xik k ) , x ∈ [a,b] .

As newly sequenced proteins are deposited into the world's ever-growing archive of protein sequences, they are typically immediately tested by various computerized algorithms for clues as to their biological structure and function. One question about a new protein involves its cellular location – that is, where the protein resides in a living organism (extracellular, intracellular, etc.). A 199...

The financial crisis that swept across northern Europe in 1763 bears an uncanny resemblance to more recent episodes of financial market turbulence in particular, to the events of autumn 1998 when mature financial markets were caught in a severe liquidity crisis, culminating in the near collapse of Long-Term Capital Management. We highlight the salient features of the 1763 crisis, propose a styl...

A: Well, yes, Yuri asked me if I wanted to write a logic column, and suggested to talk to you for some inspiration. Q: Sure, we can talk. Do you already have an idea what you will write about? A: I was thinking, perhaps I could write about first-order topological properties. Q: I suppose that is first-order as in " first-order logic " , but what's about the topol-ogy? I'm afraid I do not know m...

In an experimental 2x2 coordination game with two strict equilibria we observe that, in contrast to equilibrium selection theory (Harsanyi and Selten 1988), only half of the subjects choose the strategy that relates to the payoffand risk-dominant equilibrium. We propose modified risk dominance as an explanation for the observed deviations from payoff and risk dominance. JEL classification: C72,...

A new simple construction of an aperiodic tile set based on self-referential (fixed point) argument is proposed. People often say about some discovery that it appeared “ahead of time”, meaning that it could be fully understood only in the context of ideas developed later. For the topic of this note, the construction of an aperiodic tile set based on the fixed-point (self-referential) approach, ...
