A Sealed-Bid Unit-Demand Auction with Put Options∗
We introduce a variant of the classic sealed-bid unit-demand auction in which each item has an associated put option. The put option of an item is held by the seller of the item, and gives the holder the right to sell the item to a specified target bidder at a specified strike price, regardless of market conditions. Unexercised put options expire when the auction terminates. In keeping with the...
متن کاملSealed-Bid Auctions with Efficient Bids
Efficient general secure multiparty computation (MPC) protocols were previously proposed, and the combination with the efficient auction circuits achieves the efficient sealed-bid auctions with the full privacy and correctness. However, the combination requires that each bidder submits ciphertexts of bits representing his bid, and their zeroknowledge proofs. This cost amounts to about 80 multi-...
متن کاملAn Anonymous Sealed-bid Auction with a Feature of Entertainment
Some works about an electronic sealed-bid auction protocol have been proposed1),3),5)∼10),15),16),18). An electronic auction scheme should satisfy the following seven properties: (a)Fair of bidders; (b)Bid security; (c)Anonymity; (d)Validity of winning bids; (e)Non-repudiation; (f)Robustness; and (g)Efficient bidding points. Many previous schemes do not realize anonymity for an auction manager....
متن کاملSealed Gas UV-Photon Detector with a Multi-GEM Multiplier
A sealed gas photon detector with a GEM (Gas Electron Multiplier) cascade coupled to a semitransparent CsI photocathode has been studied. High gains, reaching 10, and fast anode signals, of a width of 15 ns, were obtained with this GEM-Photomultiplier in Ar/CH4 (95/5), in a photon counting mode. The life-time of this first prototype detector under high photon flux and large anode currents is pr...
متن کاملPlatelet Satellitism in a Three and Half Year Old Girl with Hemolytic Anemia and Normal Platelet Count
Platelet adherence surrounding leucocytes in a rosette formation or platelet satellitism is a rare phenomenon. This finding has been observed almost exclusively in Ethylenediaminetetraacetic acid treated blood at room temperature. The mechanism underlying this phenomenon is not fully understood. In many reports of platelet satellitism platelets clump to polymorphonuclear neutrophils in healthy...
