The thickness and compositions (x > y) of these heterostructures are computed in order to get: (i) the optimum quantum confinement of electrons and heavy-holes levels; (ii) the optimum out of plane oscillator strength and wave functions overlap; (iii) to satisfy a fundamental emission at a key 1.55 μm wavelength below the absorption gap of the three designed structures.
The thickness and compositions (x > y) of this single W-QW are computed in order to get (i) the optimum quantum confinement of single electrons and heavy-holes levels, (ii) the optimum out of plane oscillator strength and wave functions overlap and (iii) the requested fundamental emission at a key 1.55 μm wavelength below the absorption edge of each constitutive materials.
Holdout validation is used to assess: (i) the optimum number of samples for calculating local GM values, and (ii) the optimum scale at which to group data when using linear regression analysis to estimate GM soil ABCs from local sediment geochemical values.
The I PL optimum is reached for about 14 at.%, before decreasing for higher Si contents.
It was concluded that (i) the optimum temperature looks as a local maximum for the integrated system and as a global maximum for the sequential one, (ii) it strongly depends on the equilibrium constant of the reaction in question and (iii) it assumes lower (and economically feasible) values only in the case of the integrated unit.
Obviously, the maximum value of will be the minimum between (i) the optimum probability of transmission in a slotted transmission system (in a general sense), given by (32), and (ii) the maximum rate that can be achieved under the constraint of a probabilistic coexistence in (20).
Hence, the enhanced FE characteristics of short conical CNT films should be attributed to the following: (i) an optimum length and density combination to overcome screening effect, (ii) sharp closed tips, and (iii) open edges on the outer surface of CNTs which enhance the local field.
As Lenski and May 19944) pointed out, (i) the optimum will shift toward progressively lower virulence values as the density of the susceptible hosts is reduced by the epidemic.
Nonetheless, a number of favorable characteristics make HoBGLA an attractive biocatalyst for lactose conversion: (i) pH optimum of about 6 for lactose hydrolysis; (ii) the broad optimal stability over the pH range of 4.5 to 7.5; (iii) a temperature optimum in the range 65 70 °C; and (iv) its thermostability within the aforementioned temperature range.
Consequently, |E| = 2 > 1 therefore, we select arbitrarily λ 1 as the optimum combination, i.e., λ o = λ 1.
