Positivity reduces substantially the allowed domain for spin observables. We briefly recall some methods used to determine these domains and give some typical examples for exclusive and inclusive spin-dependent reactions.

We exhibit some new techniques to study volumes of tubes about algebraic varieties in complex projective spaces. We prove the existence of relations between volumes and Intersection Theory in the presence of singularities. In particular, we can exhibit an average Bézout Equality for equi–dimensional varieties. We also state an upper bound for the volume of a tube about a projective variety. As ...

Health inequalities across socio-economic groups in the US are large and have been growing. We hypothesize that, as in other, non-health contexts, this pattern occurs because more educated people are better able to take advantage of technological advances in medicine than are the less educated. We test this hypothesis by relating education gradients in mortality to a measure of medical innovati...
