The algorithm requires two inputs: (i) the policy P to be federated, annotated with sensitivity labels in the policy tree and (ii) the list of attributes, each having a location and sensitivity label.
The location of an attribute is either tenant-side or provider-side, the sensitivity label of an attribute or policy is a boolean that determines whether the attribute or policy can be shared with the provider or not.
Therefore, the integration location should only grant the execution of a query if the security level assigned to the data consumer is higher or equal to the sensitivity label assigned to data items returned by that query.
Numerous biosensing applications, including the detection of DNA hybridization[4], proteins[5, 6], and enzymatic activity[7, 8], have been presented, demonstrating the advantages of these nanosystems in terms of improved detection sensitivity, label-free and real-time rapid analysis.
Electrochemical biosensor holds great promise in the biomedical area due to its enhanced specificity, sensitivity, label-free nature and cost effectiveness for rapid point-of-care detection of diseases at bedside.
Surface plasmon resonance (SPR) systems have found wide use in recent years in sensing applications due to their advantage of high sensitivity, label-free, real-time, and rapid detection.
Through careful analysis of sensitivities, with focus on maximizing isotopomer sensitivity, labeling rules can be constructed, which guide the selection of C-tracers for a given network.
The optimal molecule, 2, shows superior selectivity and sensitivity, labelling ShhN at a probe concentration at least 100-fold lower than a previously reported azide-tagged cholesterol analogue, and with substantially greater labelling efficiency.
Some selected examples are presented to show the potentialities of the synthesized nanoarrays in different fields: to realize ultra-fast and tunable nonlinear optical materials, to enhance the quantum efficiency of nearby rare-earth emitters and to develop high-sensitivity, label-free biosensors.
Surface Plasmon Resonance (SPR) using antibody capture is a preferred technique for the detection of bioanalytes, in, instance, disease diagnosis, due to its high sensitivity and label free nature (Schunck, 1997; Schasfoort and Tudos, 2008).
Measured changes in relaxivities reflect specificity and sensitivity of labeling.
