We introduce a new family of dynamic mechanisms that restricts sellers from using future distributional knowledge. Since the allocation and pricing of each auction period do not depend on the type distributions of future periods, we call this family of dynamic mechanisms non‐clairvoyant.We...

In this study, it was found that a remarkably enhanced performance could be achieved in pillar array device with layered electrode through coordinate regulation between thermoelectric pillar array and layered electrode structures. The highly ordered vertical n-Bi2Te2.7Se0.3 pillar array and...

In this study, it was found that the columnar Cu film is similar as a parallel microchannel which can create some sort of channels for the easy transport of electrons and phonons in the device. The p-Bi0.5Sb1.5Te3, n-Bi2Se0.3Te2.7 and Cu films were fabricated by a magnetron sputtering method....

The Folk Theorem for repeated games suggests that finding Nash equilibria in repeated games should be easier than in one-shot games. In contrast, we show that the problem of finding any Nash equilibrium for a three-player infinitely-repeated game is as hard as it is in two-player one-shot games....
