The air gap distance d (between the two NWs) and thickness t are varied in later calculations under different metal NW radii rm and dielectric NW radii rGaN.
The calculations varied mass (10−12 to 10−3 g) and velocity (1 to 12 km/s) to reveal a distinct threshold for penetration damage.
Key input parameters and the ranges over which they have been varied in the calculations, as well as key model outputs, are summarized in Table 1.
The sample size varied in these calculations from 600 to 800 children.
Due to incomplete data collection in some cases, the denominator varied for different calculations.
bNumber represents the total number of participants in each survey; number of participants that responded to each competency varied slightly and calculations are for valid non-missing cases.
Their calculations varied also according to total inventory size and ranged between a 15,336 USD (50,000 CBU inventory) and a 92,675 USD (300,000 CBU inventory) break-even fee per CBU.
It should be noted that since the curve radius and the path radius vary, the calculation of the side friction factor constitute a complex problem, as shown in a study by Wong and Nicholson [6] who suggested that the path instead of the design radius should be taken into account.
The mean annual effective doses were estimated to be 0.7 10.4 mSv among the 5 procedures, however, the values varied with different calculation algorithms.
bDenominator for percentage calculation varied according to the number of participants included in each disease-specific analysis.
