WebJan 30, 2024 · Phase cycling is a way to selectively extract a single coherence that has evolved with a selected pathway. The only way to change a coherence is to apply a pulse by phase ϕ. Therefore, we must know the coherence pathway we are interested in and we need to set the phases of the pulses and receiver accordingly. WebAug 1, 2001 · Coherence This is similar to the biologic rationale criterion. It stipulates that there is a greater likelihood that A causes B if this postulated causal relationship is consistent with what is already known about the disease or disorder.

WebThere are essentially four ways in which gradients are used: coherence pathway selection, spatial encoding, diffusion weighting and spoiling are all used in modern high-resolution … WebBiologic Gradient Biologic gradient refers to the presence of a mono-tone (unidirectional) dose–response curve. We often expect such a monotonic relation to exist. For exam-ple, more smoking means more carcinogen exposure and more tissue damage, hence more carcinogenesis. Such an expectation is not always present, however.
WebSep 21, 2006 · When representing gradient information derived from an image, there are several options from which to choose. One such choice is the "directional derivative" that provides a vector representation. Its magnitude reflects the maximum change in pixel values while the phase is directed along the
WebOct 31, 2024 · (5) Biological gradient ("dose-response"). The more a person is exposed to A, the likelier he should be to get disease B. The more cigarettes a person smokes, the likelier he is to get lung cancer.
