This paper inquires about the ability of double auction institutions to aggregate information in the context of a " common value " information structure that is known to produce the winner's curse in sealed bid environments. While many fundamental features of the economic environment are different from those studied in the context of sealed bids, the pattern of information distributed to the po...

This paper inquires about the ability of double auction institutions to aggregate information in the context of a " common value " information structure that is known to produce the winner's curse in sealed bid environments. While many fundamental features of the economic environment are different from those studied in the context of sealed bids, the pattern of information distributed to the po...

Opsonized yeast phase Candida albicans, incubated with human neutrophils, are internalized into two classes of phagosomes. One class, termed "unsealed vacuoles," comprises approximately 40% of the total and maintains functional communication to the cell's exterior that is sufficient to permit ingress of dyes, such as trypan or methylene blue. The remaining cell-associated yeasts are contained i...

We study the role of timing in auctions under the premise that time is a valuable resource. When one object is for sale, Dutch and first-price sealed bid auctions are strategically equivalent in standard models, and therefore, they should yield the same revenue for the auctioneer. We study Dutch and first-price sealed bid auctions in the laboratory, with a specific emphasis on the speed of the ...

A second-price sealed-bid auction is that a bidder who o ers the highest price gets a good in the second highest price. This style of auction solves the problems of both an English auction and a rst-price sealed-bid auction. An electronic rst-price sealed-bid auction cannot directly be applied to a second-price sealed-bid auction which keeps the highest bid secret. We propose the veri able disc...

Security and privacy have turned out to be major challenges of the further Internet evolution in general and cloud computing, in particular. This paper proposes a novel approach to safeguard against previously unimpeded insider attacks, referred to as Sealed Cloud. A canonical set of technical measures is described, which, in conjunction, sufficiently complicate and thus economically prevent in...

Although secret sharing techniques have been applied to implement secure electronic sealed-bid auction for a long time, problems and attacks still exist in secret-sharing-based electronic sealed-bid auction schemes. In this paper, a new secret-sharing-based first-bid e-auction scheme is designed to achieve satisfactory properties and efficiency. Correctness and fairness of the new auction are b...

Human neutrophils sequester yeast cells or zymosan particles in two classes of phagocytic vacuoles: sealed and unsealed. The pH of sealed vacuoles was measured by a newly devised fluorometric procedure that used fluoresceinated zymosan particles, derived from Saccharomyces cerevisiae, as a pH probe. Five minutes after initiation of phagocytosis, sealed vacuoles were alkaline, exhibiting a pH of...
