BACKGROUND Vectorcardiogram (VCG) signals monitor both spatial and temporal cardiac electrical activities along three orthogonal planes of the body. However, the absence of spatiotemporal resolution in conventional VCG representations is a major impediment for medical interpretation and clinical usage of VCG. This is especially so because time-domain features of 12-lead ECG, instead of both spa...

We develop strategy/false-name-proof multi-unit auction protocols that can handle non-quasi-linear utilities. One almost universal assumption in auction theory literature is that each bidder has quasi-linear utility, except for some works on budget-constrained bidders. In particular, the celebrated VCG protocol is strongly believed to critically depend on the quasi-linear assumption and will br...

VCG auctions with reserve prices are practical simple auctions with provably approximately optimal revenue, and have been crucial in the analysis of other appealing auctions. When different reserve prices are applied to different bidders, the auctioneer may choose to apply the reserves either before (eagerly) or after (lazily) the comparison of bids. Both auction forms have been studied in vari...

Little is known about generating revenue in unrestricted combinatorial auctions. (In particular, the VCG mechanism has no revenue guarantees.) In this paper we determine how much revenue can be guaranteed in such auctions. Our analysis holds both in the standard model, when all players are independent and rational, as well as in a most adversarial model, where some players may bid collusively o...

The extent to which precordial and other unipolar leads are influenced by the proximity of the exploring electrode to one part or another of the heart is the subject of considerable debate. One approach to the problem is to determine how closely precordial leads can be predicted from spatial vectorcardiograms recorded by leads relatively remote from the heart. The panoramic vectors cardiograph ...
