The concept of relative bid privacy in auction is proposed, which does not conceal the bids, but conceals the link between them and the corresponding bidders. Relative bid privacy leads to two advantages: the bidding values can be very precise and any auction rule can be applied. A new mix network is designed and applied to implement relative bid privacy efficiently. Two rounds of shuffling are...

In 14 mongrel dogs wash-in and wash-out curves for halothane were obtained from measurements of arterial blood, mixed venous blood and end-tidal gas. From a certain point in the wash-in period the halothane concentration of arterial blood can be calculated from the halothane concentration in end-tidal gas and the blood-gas partition coefficient for halothane. Analysis of the curves shows that t...

We study the question of how to shuffle n cards when faced with an opponent who knows the initial position of all the cards and can track every card when permuted, except when one takes K < n cards at a time and shuffles them in a private buffer “behind your back,” which we call buffer shuffling. The problem arises naturally in the context of parallel mixnet servers as well as other security ap...

Diet composition may affect blood pressure (BP), but the mechanisms are unclear. The aim of the present study was to compare postprandial BP-related responses to the ingestion of pea protein, milk protein and egg-white protein. In addition, postprandial BP-related responses to the ingestion of maltodextrin were compared with those to the ingestion of sucrose and a protein mix. We hypothesised t...
