In an example, a single damascene structure is formed by, for example, providing a dielectric layer, forming a void in the dielectric layer, and forming a portion of a first two-terminal resistive memory cell and a portion of a second two-terminal resistive memory cell within the void. For example, an icon corresponding to an input component may be displayed proximate to a respective selectable option such that activating the input component elects the selectable option. We present the design, implementation and evaluation of Anemone\u2014an Adaptive Network Memory Engine\u2014that virtualizes the collective unused memory of multiple machines across a gigabit Ethernet LAN, without requiring any modifications to the either the large memory applications or the Linux kernel. Based on the parallel analysis, it is determined whether the potential suspect matches a person in the watch list and a result is outputted based on the determination. In addition, since users submit profile information about themselves, much demographic information is known about the users. Alternatively, the identification band may contain a person’s immigration status.
