On “Figured Me Out,” he ran his vocals through a vocoderlike filter that rendered them robotic, like the voice of Zapp’s singer Roger Troutman or a more recent cyborg aspirant, T-Pain.

These labialized stops are of course nothing but positionally determined allophones of the [t] and the [k] phoneme, and their labialization is non-distinctive

A standard theorem about finitely generated abelian groups tells us that E(ℚ) looks like qquad E(ℚ)≅( mbox FiniteGroup)⨯ underbrace {ℤ⨯ℤ⨯...⨯{Z_(r mbox copies) qquad E(ℚ)≅E(ℚ)(mbox tors)⨯ underbrace ℤ⨯ℤ⨯...⨯ℤ(r mbox copies) The finite subgroup E(ℚ)_(mbox tors) is called the qquad color red mbox TorsionSubgroupofE(ℚ).}}

Spontaneous mutations in bacteria are generally reversible. Consequently, in a medium where prototrophy confers no selective advantage, various auxotrophs (and other mutant types) should accumulate until for each type the number is such that the loss- by mutation to prototrophy should equal the gain by mutation to the corresponding auxotrophic condition.
