Introduction S ince the Internet (IP network) inception in 969, it has been assumed that servers (and therefore services) are unmovable. The IP network was designed as a static network, with the ability of dynamic routing. It is precisely its ability of dynamic routing (only possible if IP nodes are fixed in place) which is the key to its success. The IP network is self-reconfigurable by const...

Quantum-dot cellular automata (QCA) are an emerging technology and a possible alternative for faster speed, smaller size, and low power consumption than semiconductor transistor based technologies. Previously, adder designs based on conventional designs were examined for implementation with QCA technology. This paper utilizes the QCA characteristics to design a fault-tolerant adder that is more...

Cardiovascular disease (CVD) is recognized as the leading cause of mortality throughout the world. About one-third of global mortality is attributable to CVD. In addition to clinical presentation, specific clinical exam findings can assist in treating and preventing CVD. CVD may initially manifest as pulmonary pathology, and thus, accurate cardiopulmonary auscultation is paramount to establishi...

There is a serious threat that ill-considered government support for expanding legal means of controlling access to information for the purpose of extracting private economic rents is resulting in the “over-fencing of the public knowledge commons” in science and engineering. Such a new “tragedy of the commons” would bring adverse long-run consequences for future welfare gains through technologi...
