Comoving Space Density of X‐Ray–selected Active Galactic Nuclei
(IOP Publishing, 2005)For measurement of the active galactic nucleus (AGN) luminosity function and its evolution, X-ray selection samples all types of AGNs and provides reduced obscuration bias in comparison with UV excess or optical surveys. ... -
Compact Biocompatible Quantum Dots via RAFT-Mediated Synthesis of Imidazole-Based Random Copolymer Ligand
(American Chemical Society (ACS), 2010)We present a new class of polymeric ligands for quantum dot (QD) water solubilization to yield biocompatible and derivatizable QDs with compact size (~10-12 nm diameter), high quantum yields (>50%), excellent stability ... -
Compact Dielectric Elastomer Linear Actuators
(Wiley, 2018-09-04)The design and fabrication of a rolled dielectric elastomer actuator is described and the parametric dependence of the displacement and blocked force on the actuator geometry, elastomer layer thickness, voltage, and number ... -
Compact Generation of the Category of D-Modules on the Stack of G-Bundles on a Curve
(2013)The goal of the paper is to show that the (derived) category of D-modules on the stack \(Bun_G(X)\) is compactly generated. Here X is a smooth complete curve, and G is a reductive group. The problem is that \(Bun_G(X)\) ... -
Compact wavefunctions from compressed imaginary time evolution
(Royal Society of Chemistry (RSC), 2015)Simulation of quantum systems promises to deliver physical and chemical predictions for the frontiers of technology. In this work, we introduce a general and efficient black box method for many-body quantum systems using ... -
A Compactification of the Space of Expanding Maps on the Circle
(Springer Verlag, 2009)We show the space of expanding Blaschke products on \(S1\) is compactified by a sphere of invariant measures, reminiscent of the sphere of geodesic currents for a hyperbolic surface. More generally, we develop a dynamical ... -
Compactifications of F-theory on Calabi-Yau threefolds (II)
(Elsevier, 1996)We continue our study of compactifications of F-theory on Calabi-Yau threefolds. We gain more insight into F-theory duals of heterotic strings and provide a recipe for building F-theory duals for arbitrary heterotic ... -
Compactifications of F-theory on Calabi-Yau threefolds. (I)
(Elsevier, 1996)We study compactifications of F-theory on certain Calabi-Yau threefolds. We find that N = 2 dualities of type II/heterotic strings in 4 dimensions get promoted to N = 1 dualities between heterotic string and F-theory in 6 ... -
Compaction through Buckling in 2D Periodic, Soft and Porous Structures: Effect of Pore Shape
(Wiley Blackwell, 2012)Soft cellular structures that comprise a solid matrix with a square array of holes open avenues for the design of novel soft and foldable structures. Our results demonstrate that by simply changing the shape of the holes ... -

Companion Forms Over Totally Real Fields
(Springer Verlag, 2008)We show that if \(F\) is a totally real field in which \(p\) splits completely and \(f\) is a mod \(p\) Hilbert modular form with parallel weight \(2 < k < p\), which is ordinary at all primes dividing p and has tamely ... -
Companion Forms Over Totally Real Fields, II
(Duke University Press, 2007)We prove a companion-forms theorem for mod \(l\) Hilbert modular forms. This work generalises results of Gross [Gr] and Coleman and Voloch [CV] for modular forms over \(Q\) and gives a new proof of their results in many ... -
Comparative Advantage, Learning, and Sectoral Wage Determination
(University of Chicago Press, 2005)We develop a model in which a worker’s skills determine the worker’s current wage and sector. The market and the worker are initially uncertain about some of the worker’s skills. Endogenous wage changes and sector mobility ... -
Comparative Analysis and Variability of the Jovian X‐Ray Spectra Detected by the Chandra and XMM‐Newton Observatories
(American Geophysical Union, 2010)Expanding upon recent work, a more comprehensive spectral model based on charge exchange induced X‐ray emission by ions precipitating into the Jovian atmosphere is used to provide new understanding of the polar auroras. ... -
Comparative Analysis of Cas9 Activators Across Multiple Species
(2016)Several groups have generated programmable transcription factors based on the versatile Cas9 protein, yet their relative potency and effectiveness across various cell types and species remain unexplored. Here, we compare ... -
A comparative analysis of numerical approaches to the mechanics of elastic sheets
(Elsevier BV, 2015)Numerically simulating deformations in thin elastic sheets is a challenging problem in computational mechanics due to destabilizing compressive stresses that result in wrinkling. Determining the location, structure, and ... -
A Comparative Analysis of Schemes for Correlated Branch Prediction
(1995)Modern high-performance architectures require extremely accurate branch prediction to overcome the performance limitations of conditional branches. We present a framework that categorizes branch prediction schemes by the ... -
Comparative Analysis of Secretome Profiles of Manganese(II)-Oxidizing Ascomycete Fungi
(Public Library of Science, 2016)Fungal secretomes contain a wide range of hydrolytic and oxidative enzymes, including cellulases, hemicellulases, pectinases, and lignin-degrading accessory enzymes, that synergistically drive litter decomposition in the ... -
Comparative Analysis of Testis Protein Evolution in Rodents
(Genetics Society of America, 2008)Genes expressed in testes are critical to male reproductive success, affecting spermatogenesis, sperm competition, and sperm–egg interaction. Comparing the evolution of testis proteins at different taxonomic levels can ... -
