Transaction protection by beacons

Trust enhancement by multiple random beacons

Random beacons—information sources that broadcast a stream of random digits unknown by anyone beforehand—are useful for various cryptographic purposes. But such beacons can be easily and undetectably sabotaged, so that their output is known beforehand by a dishonest party, who can use this information to defeat the cryptographic protocols supposedly protected by the beacon. We explore a strateg...

Insect beacons

the applications, thereby delaying the start of this important research. Willis said: " This is a test of the government's commitment to science. Scientists, funders, the regulator and patient interest groups, even the DTI and the prime minister, have spoken out against the Department of Health's proposals. We very much hope that the department will listen and reflect the committee's conclusion...

Transaction Management: Value Creation by Reducing Transaction Costs

In this era of globalization we see an increase in specialization: the production chain is split up in more and more parts and the production of these parts is outsourced to those places in the world where production is relatively the cheapest and most efficient. This implies that transaction costs, associated with the coordination of production and trade in parts and components, become increas...

Inventing Molecular Beacons

Tripartite molecular beacons.

Molecular beacons (MBs) are hairpin-like fluorescent DNA probes that have single-mismatch detection capability. Although they are extremely useful for many solution-based nucleic acid detections, MBs are expensive probes for applications that require the use of a large number of different DNA probes due to the high cost and tedious procedures associated with probe synthesis and purification. In...
