摘要:
A method of processing semiotic data includes receiving semiotic data including at least one data set P, selecting a function h, and for at least one of each data set P to be collected, computing h(P), destroying data set P, and storing h(P) in a database, wherein data set P cannot be extracted from h(P). The method further includes selecting a private key/public key (K, k) once for all cases, one of destroying the private key K and sending the private key K to a trusted party, and choosing function h as the public encryption function corresponding to k.

Methods, systems and apparatus for characterizing networks are presented. For example, a method of characterizing a network represented by a plurality of nodes and a plurality of edges is provided. The method may be implemented on a processor device and includes calculating, for example, by the processor device, a passthrough count of at least a portion of the network. The passthrough count includes a count of a number of passthroughs in the at least a portion of the network. A passthrough includes one of the plurality of nodes, a directed edge of the plurality of edges coupled to the one of the plurality of nodes, and another edge of the plurality of edges coupled to the one of the plurality of nodes. At most one of the directed edge and the other edge is directed towards the one of the plurality of nodes. At most one of the directed edge and the other edge is directed away from the one of the plurality of nodes.

A field effect transistor device includes: a reservoir bifurcated by a membrane of three layers: two electrically insulating layers; and an electrically conductive gate between the two insulating layers. The gate has a surface charge polarity different from at least one of the insulating layers. A nanochannel runs through the membrane, connecting both parts of the reservoir. The device further includes: an ionic solution filling the reservoir and the nanochannel; a drain electrode; a source electrode; and voltages applied to the electrodes (a voltage between the source and drain electrodes and a voltage on the gate) for turning on an ionic current through the ionic channel wherein the voltage on the gate gates the transportation of ions through the ionic channel.
