Using Reactors to Measure θ13\theta_{13}

A next-generation neutrino oscillation experiment using reactor neutrinos could give important information on the size of mixing angle $\theta_{13}$. The motivation and goals for a new reactor measurement are discussed in the context of other measurements using off-axis accelerator neutrino beams. The reactor measurements give a clean measure of the mixing angle without ambiguities associated with the size of the other mixing angles, matter effects, and effects due to CP violation. The key question is whether a next-generation experiment can reach the needed sensitivity goals to make a measurement for $\sin^{2}2\theta_{13}$ at the 0.01 level. The limiting factors associated with a reactor disappearance measurement are described with some ideas of how sensitivities can be improved. Examples of possible experimental setups are presented and compared with respect to cost and sensitivity

Protecting Rights, Preventing Windfalls: A Model for Harmonizing State and Federal Laws on Floating Liens

This Article examines the conflict between state law which permits the creation of security interests in a debtor\u27s after-acquired property--or floating liens --and federal bankruptcy law\u27s potential cutoff of many of those security interests. This conflict arises in virtually every bankruptcy case. However, because of ambiguous statutory language and a failure of the jurisprudence conceptual center. This Article argues that using a model of a debtor in liquidation to analyze the cutoff of floating liens would balance the underlying policy considerations and make judicial outcomes more predictable
