Concussions and youth football: using a public health law framework to head off a potential public health crisis
(Oxford University Press, 2015)Concussion from sport is increasingly recognized as a public health priority. In response, all states and the District of Columbia have enacted youth concussion legislation. This paper first examines key developments in ... -
Condensation on slippery asymmetric bumps
(Springer Nature, 2016)Controlling dropwise condensation is fundamental to water- harvesting systems1–3, desalination4, thermal power generation4–8, air conditioning9, distillation towers10, and numerous other applications4,5,11. For any of ... -
Condensed-matter physics: Catching relativistic electrons
(Nature Publishing Group, 2014)Low-energy electrons have been found to mimic relativistic high-energy particles in cadmium arsenide. This defines the first stable '3D Dirac semimetal', which holds promise for fundamental-physics exploration and practical ... -
Conditional Universal Consistency
(Elsevier, 1999)Players choose an action before learning an outcome chosen according to an unknown and history-dependent stochastic rule. Procedures that categorize outcomes, and use a randomized variation on fictitious play within each ... -
Conducting Social Network and Social Norm Research in Low-Resource Settings: Food Insecurity, Depression, and HIV Testing in Rural Uganda
(2015-05-18)This dissertation examines the role of social networks and social norms in health outcomes and behaviors among low-and middle-income countries (LMICs), with a particular focus on Uganda. Paper 1 presents a systematic review ... -
Conductivity of weakly disordered strange metals: From conformal to hyperscaling-violating regimes
(Elsevier BV, 2015)We present a semi-analytic method for constructing holographic black holes that interpolate from anti-de Sitter space to hyperscaling-violating geometries. These are holographic duals of conformal field theories in the ... -
Confessional Fictions: Penance in Medieval Romance c.1150-1450
(2020-09-11)This study explores medieval romance in relation to religious changes from the twelfth to fifteenth centuries. While the genre has been viewed as secular literature in tension with spiritual instruction, authors such as ... -
A Configurable Terasample-per-second Imaging System for Optical SETI
(2013-10-08)A new instrument for conducting astronomical searches for nanosecond-scale optical pulses has been designed, built, and is now operating at Oak Ridge Observatory in Harvard, MA. The Advanced All-sky Camera, based on the ... -
Confined Organization of Fullerene Units Along High Polymer Chains
(Royal Society of Chemistry (RSC), 2013)Conductive fullerene \((C_{60})\) units were designed to be arranged in one dimensional close contact by locally organizing them with covalent bonds in a spatially constrained manner. Combined molecular dynamics and quantum ... -
Confinement transition to density wave order in metallic doped spin liquids
(American Physical Society (APS), 2016)Insulating quantum spin liquids can undergo a confinement transition to a valence bond solid via the condensation of topological excitations of the associated gauge theory. We extend the theory of such transitions to ... -
Confinement-Enhanced Electron Transport across a Metal-Semiconductor Interface
(American Physical Society (APS), 2001)We present a combined scanning tunneling microscopy and ballistic electron emission microscopy study of electron transport across an epitaxial Pb/Si(111) interface. Experiments with a self-assembled Pb nanoscale wedge ... -
Confinement-induced interlayer molecules: A route to strong interatomic interactions

Confinement-Induced Order of Tethered Alkyl Chains at the Water/Vapor Interface
(American Physical Society, 2002)Packing of tethered alkyl chains in Langmuir monolayers of a hairy-rod polypeptide poly[γ-4-(n-hexadecyloxy)benzyl α,L-glutamate] on water has been studied by x-ray scattering measurements at room temperature. The rods lie ... -
Confirmation of Wide-field Signatures in Redshifted 21 Cm Power Spectra
(American Astronomical Society, 2015)We confirm our recent prediction of the "pitchfork" foreground signature in power spectra of high-redshift 21 cm measurements where the interferometer is sensitive to large-scale structure on all baselines. This is due to ... -
Confirmation via the Continuum-Fitting Method That the Spin of the Black Hole in Cygnus X-1 Is Extreme
(IOP Publishing, 2014)In Gou et al., we reported that the black hole primary in the X-ray binary Cygnus X-1 is a near-extreme Kerr black hole with a spin parameter a∗ > 0.95 (3σ). We confirm this result while setting a new and more stringent ... -
Confirmed Tranquility: The Stoic Impulse in Transatlantic Romanticism
(2014-06-06)Spontaneous feeling has been a cornerstone of Romantic aesthetics since Wordsworth wrote his Preface to Lyrical Ballads. This dissertation unsettles the link between Romantic poetry and the overflow of emotion by arguing ... -
Conflict between Genetic and Phenotypic Differentiation: The Evolutionary History of a ‘Lost and Rediscovered’ Shorebird
(Public Library of Science (PLoS), 2011)Understanding and resolving conflicts between phenotypic and genetic differentiation is central to evolutionary research. While phenotypically monomorphic species may exhibit deep genetic divergences, some morphologically ... -
Conflict, Defense Spending, and the Number of Nations
(Elsevier, 2006)This paper provides a formal model of endogenous border formation and choice of defense spending in a world with international conflict. We examine both the case of democratic governments and of dictatorships. The model ... -
Conformal Bootstrap in Two Dimensions
(2016-05-18)In this dissertation, we study bootstrap constraints on conformal field theories in two dimensions. The first half concerns two-dimensional (4,4) superconformal field theories of central charge c=6, corresponding to ... -
Conformal field theories at nonzero temperature: Operator product expansions, Monte Carlo, and holography
(American Physical Society (APS), 2014)We compute the nonzero temperature conductivity of conserved flavor currents in conformal field theories (CFTs) in 2+1 space-time dimensions. At frequencies much greater than the temperature, ℏω≫kBT, the ω dependence can ...
