Traditionally, this reference is a citation taking a more or less standardized format.
Thus, what was traditionally referred to as a database, could now be considered a knowledge base, as the initially inert data points were given a machine-understandable meaning through reference to formally specified concepts in supporting ontologies.
Taking into account that many other studies throughout the last few years have reported a considerable portion of the traditionally used reference genes not being stably expressed under various experimental conditions, it becomes rather apparent that a natural constant as 1 g might have even more an effect on the expression of genes than other test circumstances.
Recently, such traditionally utilized reference genes as GAPDH and B2M have been found to be regulated in various circumstances in different tissues, emphasizing the need to identify genes independent of factors influencing the tissue, and that are stably expressed within the experimental milieu.
LRPs, traditionally computed by reference to response onset, can also be measured by reference to stimulus onset [ 16, 17], making them suitable to measure cortical responses in the absence of overt motor responses (i.e., during sleep).
His ad reminded readers that a haiku traditionally contains a reference to the season, and he added that this was "encouraged, but not required".
For those wondering if Google might further expand into territory traditionally owned by reference books — it already has.
Conventional angiography is traditionally considered the reference method for grading carotid stenosis although its accuracy for the detection of ulcerations has been questioned [94, 98, 102, 103, 104].
It is therefore questionable whether he is to be included in subsequent events, although traditionally (including in reference works like the Oxford Dictionary of Byzantium) it is held that he did share in his brothers' fate and died after 812.
GAPDH mRNA is traditionally used as the reference control in qRT-PCR; however, the transcription of Alu elements is a novel reference control that has recently been developed to replace GAPDH [ 16].
