The phrase "frequent alternation" is correct and usable in written English.
This phrase typically refers to a situation in which something changes regularly and/or frequently between two or more states. For example, you might say: "The wind speed in this region displays a frequent alternation between light and strong gusts."
Rapid and frequent alternation of different air masses separated by fronts gives Belgium considerable variability in weather.
In contrast, fish subjected to gamma-irradiation 7 months prior to behavioral testing demonstrated high within-group variability, presenting extreme behaviors of choosing one arm of the maze in all 14 consecutive trials or frequent alternation between the arms.
In contrast, such frequent alternation in GC-composition is practically absent in SRI-generated sequences.
For example, in hospitals pervasive computing has the potential to support the working conditions of hospital personnel, e.g., highly mobile and cooperative work, use of heterogeneous devices, or frequent alternation between concurrent activities [ 8]. 'Anywhere and anytime' are becoming keywords – a development often associated with 'pervasive healthcare' [ 9, 10].
Results show that the environment with acid rains tended to come into being more easily in the late Cretaceous period because of the frequent eruptions of volcanoes; and the environment of the frequent alternations of intensive freezing and thawing in the Quaternary glacial stage and the interglacial stage should have highly promoted the development of many flat grooves in the Danxia landscape.
This suggests that if the level of incongruence between two competing representations increases, neural competition increases, possibly resulting in more frequent alternations.
Our model explains how the sequential selection of cleaning modules occurs, but could it also explain the frequent alternations between cleaning the body parts and leg rubbing that occur throughout the grooming progression?
4) I felt blind-sided when, in the Results, I was told that "the frequent alternations between cleaning the body parts and leg rubbing … are an important and prominent feature in normal grooming behavior".
These results indicate that our model can explain the main observed features of the grooming progression, including the sequential cleaning of body parts and the frequent alternations between leg rubbing and body part cleaning.
Using fMRI, we investigated the neural correlate of perceptual conflict, which with prolonged viewing, leads to more frequent perceptual alternations.
We varied the probability of stimulus repetition, such that in one block repetition trials were more frequent (repetition block) while alternation trials were more frequent in the other block (alternation block).
