The phrase "a valid factor in" is correct and usable in written English.
It can be used when discussing elements that contribute to a particular outcome or decision-making process.
Example: "Cost is a valid factor in determining the feasibility of the project."
Alternatives: "a significant element in" or "an important consideration in".
However, some of the opinions and data revealed in this article show that HBCUs are still a valid factor in American higher education and should be maintained.
As far as I'm concerned, the age of the man who wants to have his finger on the nuclear button is a valid factor in the campaign.
As for the first pathway, we observed an attenuation of RR for sensory impairments after adjusting for underlying conditions and risk factors, indicating that this pathway is a valid factor in our results.
The number of valid repetitions reported for k can be shown to be O (n log n ) by the same argument as for Lemma 6; and the number of black positions in a valid factor is only a constant amount higher than for the original threshold by a similar argument to the proof of Lemma 1.
Given a weighted string x and a cumulative weight threshold 1/ z∈ 0,1], any valid repetition in x occurs in at least one extended factor. By Lemma 2, any valid factor of x occurs in at least one extended factor. By the definition of valid repetitions, any valid repetition is a valid factor.
Therefore it is sufficient to determine, for some position i, the maximum number of occurrences of its single-letter valid factors in extended factors.
All the algorithms make the assumption that the cumulative weight threshold is constant and generate the valid factors in one way or another, pruning out those that violate the threshold to avoid a combinatorial explosion.
Although the 2012 EASL-EORTC Clinical Practice Guidelines [ 12] mention that portal hypertension is a valid prognostic factor in patients undergoing resection in Asia [ 10], most cirrhotic patients in these studies have an etiological background of hepatitis C virus (HCV) and alcohol, rather than HBV (Table 5).
The fact that the absolute β-actin expression trend was identical to that of the proliferation assay implied that the expression of this housekeeping gene could be used as a valid normalization factor in assessing the expression of osteogenic marker genes.
The fitness of GAPDH as a valid normalization factor in these studies was demonstrated by examining cDNA from chondrocytes grown in 380 mosM or 550 mosM conditions using an Applied Biosystems Endogenous Control Plate (part no. 4396929) which contains 32 commonly used housekeeping genes.
It is also an attack on the idea that "hot" is a valid objectifying factor in casting ANY role that includes lines and is not called something like "The Playboy Bunny".
