The phrase "a negative quantity" is correct and usable in written English.
It can be used in mathematical or scientific contexts to refer to a value that is less than zero.
Example: "In this equation, we cannot have a negative quantity as it would not make sense in this context."
Alternatives: "a negative value" or "a negative amount".
"That has already been done, and now he is trying to reduce him to a negative quantity".
In serving their own ends they were serving public ends, while Gould was a negative quantity in the development of the country where he was not an absolutely retarding and destructive quantity.The common term of reproach against an "operator" is that he is a gambler, but it would be very unjust to apply this term to Gould.
When decelerating particles the LINAC electrode potential is treated as a negative quantity.
Thus, the sign of Equation (30) is determined by its second part, which is a negative quantity.
end{aligned} (6.38 Since (E(Omega )) is a negative quantity, from (6.35) we have that (E(B /E(Omega )ge 1).
We observe that, formally, when the real part of the variable Ω is a negative quantity, that is R e < 0, the introduced functions H and f have the following limits for quite long time intervals: lim t → ∞ H Ω, D, t = - 1 2 D Ω, when Re Ω < 0 ; (33) lim t → ∞ f Ω, t = - 1 2 Ω 2, when Re Ω < 0. (34).
The model described by (7) ("Model form and parameterization") presents a crucial error: " x a (n+1)=1− M a −1(n)" is a null or negative quantity!
At each point in time t, an individual of age j and subcohort k born at time t−j+1 consumes a non-negative quantity of a composite good c j,k,t and allocates l j,k,t time to work (total time endowment is normalized to one).
More precisely, using the notation of Figure 1, the three-population test statistic f3(C; A′, B′) estimates the sum of two directly competing terms: − αβF2(A″, B″), the negative quantity arising from admixture that we wish to detect, and α F2(A″, A) + β F2(B″, B) + F2(C, C″), a positive quantity from the "off-tree" drift branches.
The image from each chip was scaled such that the 2% trimmed mean intensity value for all arrays was adjusted to target intensity and reported as a non-negative quantity.
In this paper we first establish a new variational characterisation of spherical designs: it is shown that a set XN="{x1,…,xN}⊂Sd, where Sd:="{x∈Rd+1:∑j= 1dxj2="1}, is a spherical L-design if and only if a certain non-negative quantity AL,N XN) vanishes.
