Method and apparatus for phase shifting neurological signals received from monitoring elements of a medical device. Particularly described are oligonucleotides that are useful as hybridization probes and amplification primers, including cross-reacting hybridization probes and cross-reacting amplification primers, for detecting very low levels of viral nucleic acids. The system saves two copies of the data. The glass members include at least one slump glass member. The system may further comprises a learning unit for storing a novel answer unknown to the computer, by interrogating the user about the novel answer and further storing the interrogation scenario. an upper surface and a lower surface mutually linked by an edge ; at least a duct wherein a fluid flow can be generated by means transferring at least one sample to be treated andor analysed, and at least a valve incorporated in each duct for directing each sample thereby controlling the transfers, reactions and analyses in the device.
