Cryptographic accumulators are a tool for compact set representation and secure set membership proofs. When an element is added to a set by means of an accumulator, a membership witness is generated. This witness can later be used to prove the membership of the element. Typically, the membership witness has to be synchronized with the accumulator value: it has to be updated every time another e...

In 2001, the Centers for Disease Control and Prevention funded three Centers for Genomics and Public Health to develop training tools for increasing genomic awareness.

This paper examines the relationship between public policies and professional practices with respect to healthcare needs. Taking a theoretical-conceptual approach, practices are defined as acts that are permeated by technical-scientific and socio-historical determinants for the social production of work, and the possibilities for cultural, ethical and political changes were analyzed in order to...

Wireless Sensor Networks (WSN) have played a crucial role in many military and civilian applications. However, with the increase in popularity of such networks, the demand for security is also increasing proportionally. The new sophisticated attacks can easily compromise these resource constraint networks such as WSN. In this paper, we propose a location and energy efficient routing scheme usin...

However, we may soon have to consider very seriously a form of bigotry we now tend to overlook: age discrimination or age-ism, prejudice by one age group toward other age groups.
