... processes to produce other processes. The intentional operation on a signal produced by one process, an “input signal, ” to produce a new signal, an “output signal, ” is generally referred to as signal ... a digital link, noise in the digital link can cause errors in reconstructed bits, the bits can then be used to reconstruct the original signal within some fidelity. All of these operations on signals ... are virtually buried in noise added to them on route and in the front end amplifiers of the powerful receivers used to retrieve the signals. By suitably preparing the signals prior to transmission, by suitable filtering...

We analyzed logical relationships within microarray expression data, with attention to identifying logical combinations of proteins that led directly to the ... has previously been shown to be under-expressed in amelo- blastoma tumors while CDK5R2 has been implicated in mediating apoptosis in human glioblastoma multi- form cells. Together these observations...
