A circuit for power supply detection and power on reset. The circuit comprises two separate component groups for producing separate currents which vary in response to the level of a voltage source. For example, each may have a non-linear DC relationship between the power supply and a current of the respective component groups. Furthermore, the DC voltage to current relationship of two groups is different. The circuit has an output with two modes. The two component groups are operable to force the output into one mode when the voltage source is above a threshold and a second mode when the voltage source is below the threshold. Therefore, the circuit is operable to detect when the supply voltage has dropped below a threshold and to also serve as a power on reset. However, the circuit does not rely on the threshold voltage of a transistor to trigger the output.

A method comprising creating and storing, in memory of a computer, a graph having nodes and edges, wherein the nodes represent financial assets and any one or more of: accounts in which one or more of the assets are held; individuals who own one or more of the assets; or legal entities who own one or more of the assets; receiving and storing one or more bucketing factors and one or more column factors; the computer traversing the graph and creating a list of a plurality of paths of nodes and edges in the graph; the computer applying the bucketing factors to the paths to result in associating each set among a plurality of sets of the nodes with a different value node among a plurality of value nodes; the computer applying the column factors to the paths and the value nodes to result in associating column result values with the value nodes; creating and causing displaying a table view by forming rows based on the value nodes and forming columns based on the column result values.

A method and an apparatus useful as a secondary level assaying tool for qualitative and quantitative confirmation of results obtained by primary separation techniques and their correlation with a specific function or property of the tested sample. An apparatus is useful for the post-transfer development assaying on the solid support of the biological samples already assayed by standard separation techniques such as blotting or chromatography.
