On complexity of single-minded auction
We consider complexity issues for a special type of combinatorial auctions, the single-minded auction, where every agent is interested in only one subset of the commodities. First, we present a matching bound on the communication complexity for the single-minded auction under a general communication model. Next, we prove that it is NP-hard to decide whether Walrasian equilibrium exists in a sin...
متن کاملContent-Aware Steganography: About Lazy Prisoners and Narrow-Minded Wardens
We introduce content-aware steganography as a new paradigm. As opposed to classic steganographic algorithms that only embed information in the syntactic representation of a datagram, content-aware steganography embeds secrets in the semantic interpretation which a human assigns to a datagram. In this paper, we outline two constructions for content-aware stegosystems, which employ, as a new kind...

متن کاملCommunication and decision-making about prognosis in heart failure care.
BACKGROUND Therapies to prolong life and improve quality of life for heart failure (HF) have expanded in both number and complexity. Clinicians, patients, and families are faced with an array of decisions about interventions with complex risks and benefits. Physicians must also discuss prognosis of HF and its inherent uncertainties. METHODS AND RESULTS This article applies knowledge of partic...
متن کاملEmerging Drug Therapies for Heart Failure
Heart failure is associated with high morbidity and mortality and is proving to be an economic burden in developing countries. A number of therapeutic agents are presently employed in heart failure; but they are not sufficient to control symptoms of heart failure. Moreover, the prevalence of chronic heart failure is progressively increasing and thus there is a continuing need to develop effecti...
