For example, in the formula AH - HA = iℏ dA/dt), in which i is √(−1) and ℏ is 1/2π times Planck's constant, h, the A and H are operators, but the t is a perfectly ordinary time variable.
For example, in the formula (∀x(Axy ∨ Bx) & Bx), the occurrences of "x" in Axy and in the first Bx are bound by the quantifier.
For example, in the simple formula "(I think or I love you) and (I am or I love you not)," the string "I think and I am" pops right out and is perfectly logical.
For example, in the molecular formula CF4, Carbon (C) comes first, so we write it first: "Carbon".
For example, in the powdered formulae, average Al concentrations were 18 ng g−1 for plain milk-based, 37 ng g−1 for low-iron, 128 ng g−1 for iron supplemented, 462 ng g−1 for lactose-free, 518 ng g−1 for hypoallergenic and 619 ng g−1 for soy-based formula.
For example, in the "language" L ω,ω1), formulas will have only finitely many free variables, while there will be a host of "useless" quantifiers able to bind infinitely many free variables.[2] These informal definitions need to be tightened up in a rigorous development, but their meaning should be clear to the reader.
A more precise variant of formula (1), for example in the form of a regression equation, would be possible to derive if we had crystal structures of the same protein in all three states: protein∶protein; protein∶DNA and protein∶protein∶DNA.
In addition, infant milk formulas are now increasingly resembling human milk, for example in the area of bifidogenic effects.
For example 'In the dark'.
Direct supplementation with nucleotide precursors represents an avenue for further investigation and in humans has been found to be possible by oral means, for example in infant formula (Singhal et al., 2010).
It keeps on popping up inside as well as outside the scientific community, for example, in many formulas in geometry and trigonometry, physics, complex analysis, cosmology, number theory, general relativity, navigation, genetic engineering, statistics, fractals, thermodynamics, mechanics, and electromagnetism.
