The phrase "a shifting function" is correct and usable in written English.
It can be used in contexts where you are describing a function or role that changes or adapts over time or in response to different conditions.
Example: "In our analysis, we identified a shifting function that adjusts based on user input and environmental factors."
Alternatives: "an adaptive function" or "a variable function".
4. Now the landmarks are used as a set of samples on which a global shifting function can be interpolated.
The electrostatic potential (Eelec) was calculated by using a shift function, while a switching function (between 6.5 and 8.5 Å) was used to define the Van der Waals potential (Evdw).
Every operator that preserves the set of shifted outer functions is necessarily a product-composition operator, consisting of composition with a shifted outer function followed by multiplication with a (possibly different) shifted outer function.
A shifted Heaviside function is introduced to approximate existing cracks and crack propagations.
Previous studies using this procedure [1], [19], [20] have shown that stimulus sensitivity builds up with time according to a shifted exponential function.
The T50 value was determined by fitting a shifted sigmoid function to the thermal inactivation curves.
The resulting FIDs were zero-filled to a 2 × 1k data matrix and apodized with a shifted cosine function in both dimensions prior to Fourier transformation.
Evolutionary studies on bZIP gene families had been shown that a shifting landscape of biochemical functions related to signaling and gene expression contributed to species diversity [ 46].
Prior to 2D Fourier transformation the pseudo-2D data were multiplied with a shifted sine-squared function, zero-filled to 8k in the H dimension, and multiplied with a shifted sine-squared function, and zero-filled to 256 and 512 in the X dimension, before transformation to yield a spectral resolution of 0.2 0.4 Hz per point in the H dimension.
