The protective antigen (PA) subunit of anthrax toxin interacts with the integrin-like I domains of either of two cellular receptors, ANTXR1 or ANTXR2. These I domains contain a metal ion-dependent adhesion site (MIDAS) made up of five non-consecutive amino acid residues that coordinate a divalent metal ion that is important for PA-binding. The MIDAS residues of integrin I domains shift dependin...

The EU-IST-MIDAS project has developed middleware that helps to simplify development of software for mobile ad-hoc networks (MANET) with distributed data. One of the challenges in distributed systems is the time difference in the various nodes that are part of the MANET. Time differences can disrupt the consistency of the data stored in a distributed database upon replication. This paper argues...

We present Midas, a system that uses complex data processing to extract and aggregate facts from a large collection of structured and unstructured documents into a set of unified, clean entities and relationships. Midas focuses on data for financial companies and is based on periodic filings with the U.S. Securities and Exchange Commission (SEC) and Federal Deposit Insurance Corporation (FDIC)....
