  2. Nottingham Prognostic Index - Wikipedia

    en.wikipedia.org/wiki/Nottingham_Prognostic_Index

    The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1]

  3. Biological Magnetic Resonance Data Bank - Wikipedia

    en.wikipedia.org/wiki/Biological_Magnetic...

    The BMRB has archived sets of raw time-domain data collected from NMR experiments carried out to calculate restraints and chemical shifts in peptides, proteins and nucleic acids. This collection contains over 200 entries and in many cases the pulse-sequences and the acquisition parameters used are also available.

  4. Minimum detectable signal - Wikipedia

    en.wikipedia.org/wiki/Minimum_detectable_signal

    A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output.

  6. Pre- and post-test probability - Wikipedia

    en.wikipedia.org/wiki/Pre-_and_post-test_probability

    In clinical practice, post-test probabilities are often just estimated or even guessed. This is usually acceptable in the finding of a pathognomonic sign or symptom, in which case it is almost certain that the target condition is present; or in the absence of finding a sine qua non sign or symptom, in which case it is almost certain that the target condition is absent.

  7. Peak ground acceleration - Wikipedia

    en.wikipedia.org/wiki/Peak_ground_acceleration

    Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. [1]

  8. Eddy covariance - Wikipedia

    en.wikipedia.org/wiki/Eddy_covariance

    The eddy covariance (also known as eddy correlation and eddy flux) is a key atmospheric measurement technique to measure and calculate vertical turbulent fluxes within atmospheric boundary layers. The method analyses high-frequency wind and scalar atmospheric data series, gas, energy, and momentum, [1] which yields values of fluxes of these ...

  9. Resource-based relative value scale - Wikipedia

    en.wikipedia.org/wiki/Resource-based_relative...

    RBRVS was created at Harvard University in their national RBRVS study from December 1985 and published in JAMA on September 29, 1988. [6] William Hsiao was the principal investigator who organized a multi-disciplinary team of researchers, which included statisticians, physicians, economists and measurement specialists, to develop the RBRVS.
