A gold CD in a lift-lock case. A gold compact disc is one in which gold is utilized in place of the high-purity aluminium or silver commonly used as the reflective coating on ordinary CDs and CD-Rs respectively. Gold disks are available as both CDs and CD-Rs as well, and are compatible with standard players and recorders.
Fidelity is symmetric in its arguments, i.e. F (ρ,σ) = F (σ,ρ). Note that this is not obvious from the original definition. F (ρ,σ) lies in [0,1], by the Cauchy–Schwarz inequality. F (ρ,σ) = 1 if and only if ρ = σ, since Ψ ρ = Ψ σ implies ρ = σ. So we can see that fidelity behaves almost like a metric.
This allows gold holdings and transfers to take place in tiny fractions of a gram (equivalent to a few cents). A possible source of confusion is that gold is often priced on the open market in the more traditional troy ounce (one troy ounce is exactly 31.1034768 grams, which is larger than the avoirdupois ounce generally in use in the United ...
The quantity of gold by volume in a less-than-24-carat gold alloy differs according to the alloys used. For example, knowing that standard 18-carat yellow gold consists of 75% gold, 12.5% silver and the remaining 12.5% of copper (all by mass), the volume of pure gold in this alloy will be 60% since gold is much denser than the other metals used ...

However, the limitation is that the low-fidelity data may not be useful for predicting real-world expert (i.e., high-fidelity) performance due to differences between the low-fidelity simulation platform and the real-world context, or between novice and expert performance (e.g., due to training).

The 50th season of "SNL" premiered last month. Since the first show in 1975, 165 comedians and actors have been a part of "SNL.". Three new comedians joined for season 50. "Saturday Night Live" is ...
The 22 kt gold alloy is an English standard traditionally referred to as "crown gold". Crown gold alloys had not been used in U.S. coins since 1834, with the gold content having dropped since 1837 to a standard of 0.900 fine for U.S. gold coins. For American Gold Eagles the gold fraction was increased again to .9167 or (22 karat).
