  2. Histidine phosphotransfer domain - Wikipedia

    en.wikipedia.org/wiki/Histidine_phosphotransfer...

    Monomeric HPt domains have no enzymatic activity of their own and act purely as phosphate shuttles, [10] [4] while the dimeric Spo0B is catalytic; its phosphotransfer rate to the recipient response regulator is dramatically accelerated compared to histidine phosphate. [11]

  3. Miller twist rule - Wikipedia

    en.wikipedia.org/wiki/Miller_twist_rule

    Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]

  4. Severe plastic deformation - Wikipedia

    en.wikipedia.org/wiki/Severe_Plastic_Deformation

    During the constrained HPT process, the material experiences shear deformation between a fixed and a rotating anvil, without losing its original dimensions. High pressure torsion (HPT) can be traced back to the experiments that won Percy Bridgman the 1946 Nobel Prize in Physics, though its use in metal processing is considerably more recent. In ...

    en.wikipedia.org/wiki/Symmetric_mean_absolute...

    Provided the data are strictly positive, a better measure of relative accuracy can be obtained based on the log of the accuracy ratio: log(F t / A t) This measure is easier to analyze statistically and has valuable symmetry and unbiasedness properties

  6. Order of accuracy - Wikipedia

    en.wikipedia.org/wiki/Order_of_accuracy

    In numerical analysis, order of accuracy quantifies the rate of convergence of a numerical approximation of a differential equation to the exact solution. Consider u {\displaystyle u} , the exact solution to a differential equation in an appropriate normed space ( V , | | | | ) {\displaystyle (V,||\ ||)} .

  9. Precision and recall - Wikipedia

    en.wikipedia.org/wiki/Precision_and_recall

    In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).
