Core design for use with precision composite reflectors
A uniformly flexible core, and method for manufacturing the same, is disclosed for use between the face plates of a sandwich structure. The core is made of a plurality of thin corrugated strips, the corrugations being defined by a plurality of peaks and valleys connected to one another by a plurality of diagonal risers. The corrugated strips are orthogonally criss-crossed to form the core. The core is particularly suitable for use with high accuracy spherically curved sandwich structures because undesirable stresses in the curved face plates are minimized due to the uniform flexibility characteristics of the core in both the X and Y directions. The core is self venting because of the open geometry of the corrugations. The core can be made from any suitable composite, metal, or polymer. Thermal expansion problems in sandwich structures may be minimized by making the core from the same composite materials that are selected in the manufacture of the curved face plates because of their low coefficients of thermal expansion. Where the strips are made of a composite material, the core may be constructed by first cutting an already cured corrugated sheet into a plurality of corrugated strips and then secondarily bonding the strips to one another or, alternatively, by lying a plurality of uncured strips orthogonally over one another in a suitable jig and then curing and bonding the entire plurality of strips to one another in a single operation

A Tale of Conflicting Sovereignties: The Case Against Tribal Sovereign Immunity and Federal Preemption Doctrines Preventing States\u27 Enforcement of Campaign Contribution Regulations on Indian Tribes
This Note will discuss whether Indian tribes can assert tribal sovereign immunity to avoid compliance with state campaign finance regulation and whether such regulations should be preempted by federal law. Tribal sovereign immunity is not an enshrined constitutional imperative; it exists only under federal common law and can be limited by the courts from blocking state suits to enforce campaign finance regulations against tribes. This Note will also argue that state campaign finance regulations should not be preempted by federal law because states have a compelling interest in protecting their political processes from corruption that outweighs tribal interests in flouting the laws. States also enjoy rights arising from the text of the U.S. Constitution under the Tenth Amendment and the Guaranty Clause, which courts should recognize to permit states to regulate tribes in the context of state campaign finance laws
