The phrase "ac or ad" is not correct or usable in written English as it stands.
It appears to be an incomplete reference and lacks context for proper usage.
Example: "The choice between ac or ad can significantly impact the outcome of the project."
Alternatives: "alternatively" or "in addition".
In contrast, FAD makes no direct contacts across the AC or AD interfaces.
No gene expression pattern correlating with response could be identified for all patients, or for the AC or AD treated groups separately.
Gene expression profile predicting the response of primary breast carcinomas to AC or AD based neoadjuvant chemotherapy are most likely to be very subtle and cannot be detected when small series of patients are studied.
Although there was a high number of transcripts with significant differential expression in AM and AC or AD, the sign of some of these transcripts differed between these studies, and consequently, the meta-analysis did not detect these transcripts.
Because the AB interface is most directly affected by FAD binding, we considered whether the dimeric structure of apo AidB could be represented by AC or AD dimers, such that FAD binding would yield tetramers by bringing the A protomer of AC together with the B protomer of BD to yield ABCD tetramers.
Therefore, ∠ADC = ∠AEB and DC = EB, by step 5. Now BD = CE because BD = AD − AB, CE = AE − AC, AB = AC, and AD = AE, all by construction.
Therefore, ∠ADC = ∠AEB and DC = EB, by step 5. Now BD = CE because BD = AD − AB, CE = AE − AC, AB = AC, and AD = AE, all by construction.
Thus, there are three different types of dimers that could be formed upon deflavination: "up and down" (AB or CD dimers), "side by side" (AC or BD dimers), and "diagonal" (AD or BC dimers).
If the four parental chromosomes are labeled a, b in one parent and c, d in the other, then the genotyping problem is to infer which of the four possible segregation states or genotypes ac, ad, bc, bd describes each sample at each marker locus.
To produce the 30 crossbred half-sibs, cocks of lines A and B were mated with hens of lines C or D, resulting in crossbred hens of genotype AC, AD, BC or BD, which were tested in the practical environment.
In addition, 6 new MLVA profiles were identified (Z and AA in sheep, AE in goats, and AB, AC, and AD in cattle) which so far have not been detected in human or animal samples.
