INTRODUCTION The ultimate aim in transfusing blood is the maintenance or restoration of a medium for the transport of oxygen to body tissues. Most often, the efficacy of transfusion therapy is evaluated by survival of the donor erythrocytes in the recipient. However, red cells may have a normal in vivo survival yet be unable to bind and unload oxygen physiologically. In 1956, Valtis and Kennedy...

We present the design of a distributed store that offers various levels of security guarantees while tolerating a limited number of nodes that are compromised by an adversary. The store uses secret sharing schemes to offer security guarantees namely availability, confidentiality and integrity. However, a pure secret sharing scheme could suffer from performance problems and high access costs. We...

In this paper we define and give a solution to the problem of identification of passwords on media. Because of the proliferation of useful websites and accounts for finance, commerce and entertainment, the typical user today often needs to store passwords on their computer hard drive or on a cell phone. The identification problem is to identify strings on the disk that could likely be passwords...

In this paper, we demonstrate a technique called active probing used to study TCP implementations. Active probing treats a TCP implementation as a black box, and uses a set of procedures to probe the black box. By studying the way TCP responds to the probes, one can deduce several characteristics of the implementation. The technique is particularly useful if TCP source code is unavailable. To d...

Abstract: During the last few years message queuing and workflow systems have been established as major elements of the software stack. In practice, this middleware is often used to cope with aspects of data federation: Message queuing technology is exploited for application integration. Workflows extend the notion of stored procedures in a federated environment and provide transaction manageme...
