Carbon nanotubes (CNT) possess many unique characteristics that promise to revolutionize the world of structural m a-terials resulting in significant impact on our capability to build lighter, smaller and higher performance structures for aerospace and many other industrial applications. When the CNT are aligned, micromechanical studies showed the p(More)

STUDY OBJECTIVES Functional neuroimaging studies suggest a prominent role for the medial prefrontal cortex in the formation of moral judgments. Activity in this region has also been shown to decline significantly during sleep loss. We therefore examined the effects of 2 nights of sleep deprivation on several aspects of moral judgment.

—We explore several image processing methods to automatically identify the make of a vehicle based focused on the manufacturer's iconic logo. Our findings reveal that large variations in brightness, vehicle features in the foreground, and specular reflections render the scale-invariant feature transform (SIFT) approach practically useless. Methods such as(More)
Fundamental Questions/Challenges Future Work/Unanswered Questions § The timings of messages in a communications channel convey information. This makes covert communication across a network realizable. § 1949: Shannon's Channel Capacity Theorem characterized the capacity, or theoretical rate limit for arbitrarily reliable communication, in a channel with(More)
We examine the extent of policy experimentation under decentralization and cen-tralization. More specically, we study the incentive for experimentation in an environment where there is uncertainty about the payo of policies as well as the competence of policymakers. Voters form beliefs about the policymakers upon observing noisy signals. Policymakers are(More)
We propose an alternative approach to modeling strategic voting in large elections. In particular, we examine strategic voting in the presence of ethical voters, who follow a group-welfare maximizing voting rule. This rule may require them to vote strategically, that is, to vote for a candidate that is not their most preferred. The model delivers(More)

A party develops its identity by adopting biased policy positions consistently over time. Existing rational voting models explain distinct party identities by assuming intrinsic policy-motivated parties or candidates. We show that distinct party identities may arise when parties are purely oce-motivated in a dynamic setting with impressionable voters. In(More)
