Use Relative Refractory Period when you need to compute the fraction of relative refractory recovery clamped to 0..1 from elapsed time, the absolute refractory duration, and the relative recovery window. Enter Absolute refractory period, Elapsed time, and Relative window using the definitions and units below so the result can be reproduced.

Absolute refractory period

Absolute refractory duration; defaults to 1 ms.

Elapsed time

A finite measured or assumed value greater than or equal to 0, expressed in ms.

Relative window

Relative recovery window length; strictly between 0 and 50 ms, defaults to 3 ms.

The published tool contract uses this rule: Compute the fraction of relative refractory recovery clamped to 0..1 from elapsed time, the absolute refractory duration, and the relative recovery window.

Recovery fraction

The calculated recovery fraction.

A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small. Absolute refractory period must remain between 0.1 and 10.

Retain the original Absolute refractory period, Elapsed time, and Relative window values and their units alongside the result. Absolute Refractory Check is useful when you instead need to check whether a neuron is inside its absolute refractory period by comparing elapsed time since the last spike against the absolute refractory window. Relative Growth Rate provides another view by helping you compute plant relative growth rate RGR per day as (ln W2 - ln W1) / elapsed days from dry masses measured at two times.

• Absolute Refractory Check

  Check whether a neuron is inside its absolute refractory period by comparing elapsed time since the last spike against the absolute refractory window.

• Relative Growth Rate

  Compute plant relative growth rate RGR per day as (ln W2 - ln W1) / elapsed days from dry masses measured at two times.

• Relative Fitness

  Compute relative fitness w = survived offspring / maximum survived offspring in the population.
