The phrase "a simple expression and" is correct and usable in written English.
It can be used when introducing a straightforward idea or concept that is being elaborated upon or connected to another thought.
Example: "In mathematics, a simple expression and its components can often reveal deeper insights into the problem at hand."
Alternatives: "a straightforward phrase and" or "an uncomplicated statement and".
Hence, it appears unlikely that a freshly retroposed gene could already fully substitute the parental copy, as it is assumed that retrogenes start with a simple expression pattern and acquire more complex regulation later [ 20].
If (g > g^{ast }); then one is (x_{I_{1,2}} = 0), whereas the others can be found by inverting a simple expression relating g and (x_{I_{1}}) along the solution branch: -x_{I_{1}} + frac{alphamu_{E}}{sqrt{N}}tanh(g x_{I_{1}}) = 0quad Rightarrowquad g = frac{1}{x_{I_{1}}} tanh^{-1} biggl( frac{sqrt {N}x_{I_{1}}}{alphamu_{E}} biggr).
For high κ, our results agree with a simple expression including only bending and tension, while for lower κ entropy must also be taken into account.
The first message, concealed under layers of paint and vitriol, was a simple expression of frustration at the corporate and bank bailouts of recent years.
At the first look, this probability is similar to that in the previous section; however, it is noted that, in the scenario of OFDM, channel gains in subcarriers are correlated and a simple expression using binomial distribution as in the previous section is not applicable.
Emphasis is placed on capturing the finite rate chemistry effects and obtaining a simple expression for the mean reaction rate.
Using asymptotic arguments, explicit expressions of the spectral efficiency are obtained and provide a simple expression of the network spectral efficiency based only on a few meaningful parameters.
A simple expression that uses the numerical results and allows ready calculation of pressure gradient from homogenizer operating and design conditions is presented.
We recall hereafter the Legendre type conditions with Poisson brackets to show that geometric optimal control allows a simple expression of the second-order necessary and sufficient conditions (see Theorem 2).
Existing modeling work either uses oversimplified assumption of pressure distribution in the coating bead, or does not provide a simple expression to predict the penetration depth and often requires a complex calculation procedure.
