The phrase "among the two systems" is not correct in standard English usage.
The correct expression should be "between the two systems," as "between" is used for two entities, while "among" is used for three or more.
Example: "The differences between the two systems are significant and should be carefully considered."
Alternatives: "in relation to the two systems" or "in comparison to the two systems."
There were three different groups according to the relations among the two system codes: 1) no relation (one code in ICPC-2 with no equivalent in ICD-9-CM), 2) univocal relation (one code in ICPC-2 had a single correspondence in the ICD-9-CM, this was the optimal situation) and 3) multiple relations (one code in ICPC-2 had several possible codes in ICD-9-CM).
For now, the two systems -- among the largest energy consumers in the state -- are being supplied by Pacific Gas and Electric and Southern California Edison.
As a result, they say, increasing levels of serotonin with antidepressants can cripple the sex drive but also set off an imbalance among the three systems.
Seasonal NO3-N dynamics among the three systems were explainable based on mineralization and – immobilization of N from decomposing crop residues.
The stable evolution of Rp, Cp, Cd, and a higher value of Rc illustrated an original fact that the water-borne styrene-acrylate emulsion/Dacromet system exhibited the best protective performance among the three systems.
The map is generated based on comparisons among the four systems with a goal of increasing the net power output by 20% under the condition that the SF is replaced by one of the upgraded systems (DF, FORC, and DFORC).
In Figure 5, if 20≤10 log10≤90, the value of P ′ is mostly less than P ′′ under the same system configuration with the same ρ since in all the considered system configurations n T =n R such that Δζ = ζ p ¯ − ζ 0 grows as n R increases, which might be why we see both P ′ and P ′′ of n T =n R =8 system as the largest among the three systems.
