Antitrust & Corruption: Overruling Noerr, Tim Wu

Faculty Scholarship

We live in a time when concerns about influence over the American political process by powerful private interests have reached an apogee, both on the left and the right. Among the laws originally intended to fight excessive private influence over republican institutions were the antitrust laws, whose sponsors were concerned not just with monopoly, but also its influence over legislatures and politicians. While no one would claim that the antitrust laws were meant to be comprehensive anti-corruption laws, there can be little question that they were passed with concerns about the political influence of powerful firms and industry cartels.

Constant Intensity Conical Diffraction In Discrete One-Dimensional Lattices With Charge-Conjugation Symmetry, Mojgan Dehghani, Cem Yuce, Tsampikos Kottos, Hamidreza Ramezani

Physics & Astronomy Faculty Publications

We engineer anomalous conical diffraction (CD), occurring in discrete one-dimensional lattices with chargeconjugation symmetry when an exceptional point is in the proximity of the modes that compose the initial excitation. The evolving waveform propagates ballistically, acquiring a constant intensity profile within the boundaries of the spreading cone. The linear increase in the total intensity along the propagation direction is responsible for the generation of constant intensity CD.

Big Brother, Othello, And Dogs That Don't Bark: The Use Of Literary Allusion In Federal Appellate Opinions, Kristin B. Gerdy

Faculty Scholarship

Unlike a fish, in the words of Justice Elena Kagan, a literary5 allusion is not “a discrete thing that possesses physical form”6 distinguishable from other expressive devices. Instead, literary allusions can take many forms, be used for many purposes, and have various effects on the reading audience. If the most basic form of a fish is the common goldfish in a bowl, then the most basic judicial literary allusion is a reference to a well-known story in a judicial opinion that is used to make a comparison in a reader’s mind. But just as there are many types of fish …
