A Chiral N-Crotonyloxazolidinone Diels-Alder Adduct
(International Union of Crystallography, 1992)(4S)-4-Benzyl-3-[(4S,5S)-(1-methoxy-5-methylcyclohexen-4-yl) carbonyl]-2-oxazolidinone, C<sub>19</sub>H<sub>23</sub>NO<sub>4</sub>, <i>M</i>,=329.40, monoclinic, <i>P</i>2<sub>1</sub>, <i>a</i>=11.453(3), <i>b</i>=7.163(4), ... -
Chiral Prethermalization in Supersonically Split Condensates
(American Physical Society (APS), 2014)We study the dynamics of phase relaxation between a pair of one-dimensional condensates created by a supersonic unzipping of a single condensate. We use the Lorentz invariance of the low energy sector of such systems to ... -
Chiral Principal Series Categories
(2014-06-06)This thesis begins a study of principal series categories in geometric representation theory using the Beilinson-Drinfeld theory of chiral algebras. We study Whittaker objects in the unramified principal series category. ... -
Chiral rings in N = 2 superconformal theories

Chiral Scale and Conformal Invariance in 2D Quantum Field Theory
(American Physical Society, 2011)It is well known that a local, unitary Poincaré-invariant 2D quantum field theory with a global scaling symmetry and a discrete non-negative spectrum of scaling dimensions necessarily has both a left and a right local ... -
Chiral Sulfinamide/Achiral Sulfonic Acid Cocatalyzed Enantioselective Protonation of Enol Silanes
(American Chemical Society, 2011)The application of chiral sulfinamides and achiral sulfonic acids as a co-catalyst system for enantioselective protonation reactions is described. Structurally simple, easily accessible sulfinamides were found to induce ... -
Chiral Sulfinamidourea and Strong Brønsted Acid–Cocatalyzed Enantioselective Povarov Reaction to Access Tetrahydroquinolines
(Nature Publishing Group, 2014)This protocol describes a method for the laboratory synthesis of enantiomerically enriched, chiral tetrahydroisoquinolines through the application of a chiral sulfinamido urea catalyst for the Povarov reaction. ... -
Chiral Thioureas Promote Enantioselective Pictet–Spengler Cyclization by Stabilizing Every Intermediate and Transition State in the Carboxylic Acid-Catalyzed Reaction
(American Chemical Society (ACS), 2017-08-22)An investigation of the mechanism of benzoic acid/thiourea co-catalysis in the asymmetric Pictet-Spengler reaction is reported. Kinetic, computational, and structure-activity relationship studies provide evidence that ... -
Chirality of Light and Its Interaction with Chiral Matter
(2013-03-18)This thesis conducts a systematic study on the chirality of light and its interaction with chiral matter. In the theory section, we introduce a measure of local density of chirality, applying to arbitrary electromagnetic ... -
Chirality-Dependent Friction of Bulk Molecular Solids
(American Chemical Society (ACS), 2014)We show that the solid−solid friction between bulk chiral molecular solids can depend on the relative chirality of the two materials. In menthol and 1-phenyl-1-butanol, heterochiral friction is smaller than homochiral ... -
Chirality-dependent G-band Raman intensity of carbon nanotubes
(American Physical Society, 2001)The chirality-dependent G-band Raman intensity of single wall carbon nanotubes is calculated using a nonresonant theory for the Raman tensor. We obtain six or three intense Raman modes, respectively, for chiral or achiral ... -
Chiroptical Hot Spots in Twisted Nanowire Plasmonic Oscillators
(AIP Publishing, 2013)We image the chiroptical response of crossed nanowire junctions as a function of the vertical offset between the nanowires and the incident wavelength. These samples show chiroptical “hot spots” with strongly localized ... -
The Choice for Multilateralism: Foreign Aid and American Foreign Policy
(Springer Nature, 2012-09-15)Why do governments choose multilateralism? We examine a principal-agent model in which states trade some control over the policy for greater burden sharing. The theory generates observable hypotheses regarding the reasons ... -
A Choice Prediction Competition for Market Entry Games: An Introduction
(MDPI AG, 2010)A choice prediction competition is organized that focuses on decisions from experience in market entry games (http://sites.google.com/site/gpredcomp/ and http://www.mdpi.com/si/games/predict-behavior/). The competition is ... -
A Choice Prediction Competition for Social Preferences in Simple Extensive Form Games: An Introduction
(MDPI AG, 2011)Two independent, but related, choice prediction competitions are organized that focus on behavior in simple two-person extensive form games http://sites.google.com/site/extformpredcomp/): one focuses on predicting the ... -
A Choice Prediction Competition: Choices From Experience and From Description
(John Wiley and Sons, 2009)Erev, Ert, and Roth organized three choice prediction competitions focused on three related choice tasks: one shot decisions from description (decisions under risk), one shot decisions from experience, and repeated decisions ... -
A Choice, Not an Echo: Polarization and the Transformation of the American Party System
(2014-06-06)This dissertation offers an intellectual and institutional history of party polarization and ideological realignment in the postwar United States. It treats the construction of an ideologically sorted party system as a ... -
