The phrase "a brief calculation" is correct and usable in written English.
You can use it when referring to a quick or simple mathematical computation or estimation.
Example: "To determine the total cost, we need to perform a brief calculation of the expenses involved."
Alternatives: "a quick calculation" or "a simple calculation".
This case study shows how a brief calculation using only a crude structural approximation can give insight regarding allosteric regulation in large biomolecular complexes.
A brief calculation verifies that equation (37) has no solutions for β < β 1, while for β > β 1, there are two solutions, ( β, t ̲ in { β t < 1 } and ( β, t ¯ in { β t > 1 }.
To verify (21), we first note that both sides of (21) are zero at t = 0. We next carry out a brief calculation to show that the right-hand side solves the differential equation in (6), which the left-hand side solves by definition.
A brief calculation shows that α 2 = ∏ i = 1 K (s ik / s ′ ik ) γ k − 1.
A brief calculation suggests that at these time scales diffusion alone is unable to warrant a supply of fresh dye molecules and prevent signal loss.
The brief calculation process follows.
Brief calculation details of these statistics are given in the appendix [ 9- 12].
Brief calculations shows that, with just $50 billion, less than one-third of AIG's total, you could create some 2 million $25,000 a year jobs for local health educators to teach good self-care to every pre-diabetic in the United States, thereby slashing future Medicaid and Medicare costs by truly untold billions.
A brief density functional calculation was conducted to have an insight into the electronic structure characteristic of the bis-4-MOSB in the scintillation process.
A brief description of its calculation is presented here, as this method is used in the present study.
We present a brief description of our calculations below, and more details are given in the Appendix.
