The Chagos Archipelago was designated a no-take marine protected area (MPA) in 2010; it covers 550 000 km(2), with more than 60 000 km(2) shallow limestone platform and reefs. This has doubled the global cover of such MPAs.It contains 25-50% of the Indian Ocean reef area remaining in excellent condition, as well as the world's largest contiguous undamaged(More)
Classical and semiclassical methods are unrivaled in providing an intuitive and computationally tractable approach to the study of atomic, molecular, and nuclear dynamics. An important advantage of such methods is their ability to uncover in a single picture underlying structures that may be hard to extract from the profusion of data supplied by detailed(More)
We present a Next-to-Leading order perturbative QCD analysis of world data on the spin dependent structure functions g p 1 , g n 1 , and g d 1 , including the new experimental information on the Q 2 dependence of g n 1. Careful attention is paid to the experimental and theoretical uncertainties. The data constrain the first moments of the polarized valence(More)
