Separation may lead to impredicativity in case the formula φ contains unbounded quantifiers ranging over the whole universe of sets; in fact, in defining the new set by separation we may thus refer to this very set, contradicting Russell's VCP.
The estimates of ERR/Gy for the various categories of age at first childbirth, number of children, menopausal status and ovarian dose were very similar, contradicting any interaction effects on the scale of relative risk.
First, numerous studies reported elevated startle responses in PTSD both in human patients [ 73– 75, 131] and in animal models [ 77– 80, 103], with only very few contradicting results [ 132, 133].
There is no way that human birth rates could outpace this, so our very existence contradicts the existence of vampires.
Its very existence contradicts the idea that every person is redeemable and every human life is worth saving.
Cephalochordates (amphioxus) have been traditionally considered to be the primitive chordates that most resemble vertebrates, but this view has been very recently contradicted by the genome sequence data that suggests that tunicates (which include the ascidians), are more closely related to vertebrates than cephalochordates [ 59].
Such representations of providers (particularly nurses) as "not nice" or "very bad" contradict and threaten their stated raison d'etre of altruism and professionalism, and many nurses in our study expressed hurt, anger, demotivation, and even withdrawal from the contract as a consequence.
Linear gradients gave very efficient chemotaxis, contradicting earlier results suggesting that only polynomial gradients were effective.
None of the obviously incorrect groupings (i.e., those contradicting very strong previous evidence) based on composition alone are also found in likelihood or distance analysis based on standard substitution models.
