Horn Concerto in E-flat Major (C41) by Antonio Rosetti: A Critical Edition

Description: This project delivers to the scholar and performer a critical edition of a little-known horn concerto by Antonio Rosetti. Standing in contrast to performance or practical editions, critical editions demand that the editor exerts a non-trivial measure of authority over the state of the text. Performers often find this fact to be uncomfortable given the normal tendency to revere the perceived intent of the composers based upon the text that they set down. When engaging with sources, it is rarely … more

Impact of Market State on Momentum Portfolio Risk and Performance: A Risk-Based Explanation

Description: The momentum puzzle, i.e., stocks that have performed better in the past tend to perform better in the future, has been a constant challenge to classic finance theory. Prior research has failed to provide valid risk-based explanations because winner portfolios do not exhibit higher risk characteristics. Without a convincing risk explanation, the persistence of momentum profit is a violation of the efficient market hypothesis. Today, the momentum puzzle remains one of the very few major anomalie… more

Manipulation of Light-Matter Interactions in Molybdenum Disulfide (MoS2) Monolayer through Dressed Phonons (DP) and Plasmons

Description: The performance of electrical and optical devices based on two-dimensional semiconductors (2D) such as molybdenum disulfide is critically influenced due to very poor light absorption in the atomically thin layers. In this study, the phonon mediated optical absorption and emission properties in single atomic layers of MoS2 have been investigated. The electronic transitions in MoS2 due to near-field optical interaction and the influence of interface phonons due to the dielectric substrate GaN on … more
