The phrase "fluctuate about" is grammatically correct and can be used in written English.
It means to vary or change frequently and unpredictably. Example: The stock prices have been fluctuating about for the past few months, making it difficult for investors to make any long-term decisions.
I say roughly, because the Bugatti's price can fluctuate about $14,000 a day simply from one-cent adjustments in exchange rates.
(3) As for carbon price, the uniform-price auction might generate a slightly higher market clearing price than the discriminative-price auction, and the prices under two auction rules fluctuate about RMB 40 per metric ton.
We combine the HLSVC interface advection algorithm with a two phase flow solver in order to numerically capture deforming bubbles and drops whose actual volume (s) fluctuate about fixed "target" volume (s).
A server's load at any one instant in time may fluctuate about a fixed threshold value.
Since r.v.'s Hf,n and Hs,n are independent of each other, and since E { H f, n } = E { H s, n } = 1, from (1) we have E { H n } = H pl, n, which reflects the fact that the Rayleigh fading and shadowing components cause the actual gain H N to fluctuate about its mean value Hpl,n.
As r.v.'s Gf,nand Gs,nare independent from each other, and as E G f, n = E G s, n = 1, we have, from (1), E G n r n = G p l, n r n, which reflects the fact that the n th interfering channel's Rayleigh fading and shadowing components cause the actual gain G n (r n ) to fluctuate about its mean value Gpl,n(r n ).
Recently, we have shown for asymptomatic populations that BMLs fluctuate with about 50% resolving and about 14% of people developing new ones over two years [ 12, 30].
The existence of three states at all glucose concentrations indicates that the protein continuously fluctuates about its conformational state space via thermally driven state transitions; glucose biases the populations by reorganizing the free energy profile.
The problem is relevant to the vibration of machine structures or mechanisms in which the excitation frequency, in the course of a cycle of operation for example, fluctuates about its average value.
As Table 2 shown, κ(K) fluctuates about 1010 which is large enough to stand for ill-posed system.
We found that a detection accuracy of Sr and Ti atoms fluctuates about 0.85 (±0.06) for λ ≤ 0.4, and falls off precipitously for λ > 0.4.
