Studies on models synthesized by stereochemically controlled routes show that the central triene chromophore in the common cis isomer of phytoene has the irans,cis,trans configuration, and that the phytoene from Flavobacterium dehydrogenans consists mainly of the all-trans isomer. Capsorubin, with the natural configuration at all four chiral centres, has been synthesized from (+)-camphor. Sever...

Several processes might explain the non-linear relationship between proliferation and conflict. Nominal nuclear status could constitute a capability shock, altering the balance of power and increasing the probability of ...

Existing nuclear deterrence scholarship evinces a pervasive ‘‘existential bias,’’ assuming that once a state merely possesses nuclear weapons, it should be able to deter armed conflict. The empirical literature expresses this bias by simply dichotomously coding a state based on whether it has nuclear weapons, thereby treating all nuclear states as equivalent. Thus, whether nuclear weapons deter...
