The ‘midpoint’ approximation to the integral $$\int_0^1 f $$ is $${M_n}\left( \right) = {1 \over n}\sum\limits_{r 1}^n \left( {{{2r - 1} {2n}}} \right)$$ .
OBJECTIVE To study changes in midpoint lumbar disc heights in an asymptomatic Jordanian sample relative to age, sex, lumbar level and midvertebral heights. METHODS A total of 153 asymptomatic patients (87 males, age range 20-65 years; mean 43+/-12.1 and 66 females, age range 22-68 years; mean 47+/-13.7) were selected during the study period. All underwent midsagittal magnetic resonance imagin...
The category variability effect refers to that people tend to classify the midpoint item between two categories as the category more variable. This effect is regarded as evidence against the exemplar model, such as GCM (Generalized Context Model) and favoring the rule model, such as GRT (i.e., the decision bound model). Although this effect has been found in conceptual category learning, it is ...
INTRODUCTION Multiple sclerosis (MS) is a chronic disease of the central nervous system. Estimates of MS natural history (NH) disability progression speed from clinical observations vary worldwide. This may reflect, in part, variance in censoring-bias) (missing observations) and assumptions about when irreversible disability progression events occurred. We test whether estimates of progression ...
We have measured the redox potentials for the flavin cofactor of native Old Yellow Enzyme and for a series of chemically modified flavin derivatives bound to the apoprotein. These flavin derivatives have midpoint potentials ranging from -120 to -300 mV in free solution. For the native enzyme, the midpoint potential of the first one-electron couple EFMNox + e- in equilibrium EFMN-. is E1 = -245 ...
