Coaxial Atomic Force Microscope Tweezers
(American Institute of Physics, 2010)We demonstrate coaxial atomic force microscope (AFM) tweezers that can trap and place small objects using dielectrophoresis (DEP). An attractive force is generated at the tip of a coaxial AFM probe by applying a radio ... -
Coaxial multishell nanowires with high-quality electronic interfaces and tunable optical cavities for ultrathin photovoltaics
(Proceedings of the National Academy of Sciences, 2012)Silicon nanowires (NWs) could enable low-cost and efficient photovoltaics, though their performance has been limited by nonideal electrical characteristics and an inability to tune absorption properties. We overcome these ... -
Cocaine Enhances DC to T-cell HIV-1 Transmission by Activating DC-SIGN/LARG/LSP1 Complex and Facilitating Infectious Synapse Formation
(Nature Publishing Group, 2017)DC-SIGN is a dendritic cell surface structure which participates in binding and transmission of HIV-1. Here, for the first time we demonstrate that cocaine induces over expression of DC-SIGN and significantly enhances virus ... -
CodeBlue: An Ad Hoc Sensor Network Infrastructure for Emergency Medical Care
(2004)Sensor devices integrating embedded processors, low-power, low-bandwidth radios, and a modest amount of storage have the potential to enhance emergency medical care. Wearable vital sign sensors can track patient status and ... -
Codes for Deletion and Insertion Channels with Segmented Errors
(2006)We consider deletion channels and insertion channels under an additional segmentation assumption: the input consists of disjoint segments of b consecutive bits, with at most one error per segment. Under this assumption, ... -
Coding and Transformations in the Olfactory System
(Annual Reviews, 2014)How is sensory information represented in the brain? A long-standing debate in neural coding is whether and how timing of spikes conveys information to downstream neurons. Although we know that neurons in the olfactory ... -
Coding Approaches for End-to-End 3D TV Systems
(Mitsubishi Electric Research Laboratories, 2004)We present a 3D TV prototype system with real-time acquisition, transmission and auto-stereoscopic display of dynamic scenes. Our system uses a distributed, scalable architecture to manage the high computation and bandwidth ... -
The coevolution of life and environments

Coexistence of Gapless Excitations and Commensurate Charge-Density Wave in the 2H Transition Metal Dichalcogenides
(American Physical Society (APS), 2006)An unexpected feature common to 2H transition metal dichalcogenides (2H TMDs) is revealed with a first-principles Wannier function analysis of the electronic structure of the prototype 2H TaSe2: The lowenergy Ta ‘‘5dz2 ’’ ... -
Coexistence of the Meissner and Vortex States on a Nanoscale Superconducting Spherical Shell
(American Physical Society, 2009)We show that on superconducting spherical nanoshells, the coexistence of the Meissner state with a variety of vortex patterns drives the phase transition to higher magnetic fields. The spherical geometry leads to a ... -
Coexisting conical bipolar and equatorial outflows from a high-mass protostar
(Springer Nature, 1998)The BN/KL region in the Orion molecular cloud1 is an archetype in the study of the formation of stars much more massive than the Sun2. This region contains luminous young stars and protostars, but it is difficult to study ... -
Cofabrication: A Strategy for Building Multicomponent Microsystems
(American Chemical Society (ACS), 2010)This Account describes a strategy for fabricating multicomponent microsystems in which the structures of essentially all of the components are formed in a single step of micromolding. This strategy, which we call ... -
Cofactor bypass variants reveal a conformational control mechanism governing cell wall polymerase activity
(National Academy of Sciences, 2016)To fortify their cytoplasmic membrane and protect it from osmotic rupture, most bacteria surround themselves with a peptidoglycan (PG) exoskeleton synthesized by the penicillin-binding proteins (PBPs). As their name implies, ... -
Cognition is Recognition: Literary Knowledge and Textual “Face”
(Johns Hopkins University Press, 2013)Our language for the truths of literature is reformist and nominalist; our experience of reading is, by contrast, habitual and idealist. Contrary to the way we talk about what kind of new, liberatory truths literature ... -
Cognitive and linguistic factors affecting subject/object asymmetry: An eye-tracking study of prenominal relative clauses in Korean
(Muse - Johns Hopkins University Press, 2010)Object relatives (ORs) have been reported to cause heavier processing loads than subject relatives (SRs) in both pre- and postnominal position (prenominal relatives: Miyamoto & Nakamura 2003, Kwon 2008, Ueno & Garnsey 2008; ... -
Cognitive and Neural Mechanisms Underlying Visual and Semantic Processing: Implications from “Optic Aphasia”
(Massachusetts Institute of Technology Press, 1995)We report detailed analyses of the performance of a patient, DHY, who as a consequence of strokes in the left occipital lobe and the periventricular white matter in the region of the spleniuni, showed severely impaired ... -
Cognitive Aspects of Nonclinical Obsessive-Compulsive Hoarding
(Elsevier, 2007)Research on the cognitive variables associated with obsessive-compulsive hoarding is scarce. In this study, we investigated cognitive variables that may contribute to the maintenance and possibly etiology of hoarding. ... -
Cognitive capacities for cooking in chimpanzees
(The Royal Society, 2015)The transition to a cooked diet represents an important shift in human ecology and evolution. Cooking requires a set of sophisticated cognitive abilities, including causal reasoning, self-control and anticipatory planning. ... -
The Cognitive Consequences of Emotion Regulation: An ERP Investigation
(Blackwell Publishers, 2008)Increasing evidence suggests that emotion regulation (ER) strategies modulate encoding of information presented during regulation; however, no studies have assessed the impact of cognitive reappraisal ER strategies on the ... -
Cognitive Effects of Language on Human Navigation
(Elsevier, 2011)Language has been linked to spatial representation and behavior in humans, but the nature of this effect is debated. Here, we test whether simple verbal expressions improve 4-year-old children’s performance in a disoriented ...
