Carbon Nanotube Atomic Force Microscopy Tips: Direct Growth by Chemical Vapor Deposition and Application to High-Resolution Imaging
(National Academy of Education, 2000)Carbon nanotubes are potentially ideal atomic force microscopy probes because they can have diameters as small as one nanometer, have robust mechanical properties, and can be specifically functionalized with chemical and ... -
Carbon Nanotube-Based Nonvolatile Random Access Memory for Molecular Computing
(American Association for the Advancement of Science, 2000)A concept for molecular electronics exploiting carbon nanotubes as both molecular device elements and molecular wires for reading and writing information was developed. Each device element is based on a suspended, crossed ... -
Carbon Nanotubes for Coherent Spintronics
(Elsevier Science Limited, 2010)Carbon nanotubes bridge the molecular and crystalline quantum worlds, and their extraordinary electronic, mechanical and optical properties have attracted enormous attention from a broad scientific community. We review ... -
Carbon Taxes, Path Dependency, and Directed Technical Change: Evidence from the Auto Industry
(University of Chicago Press, 2016)Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between "dirty" (internal combustion engine) and "clean" (e.g. electric and ... -
Carbon- and nitrogen-quality signaling to translation are mediated by distinct GATA-type transcription factors
(National Academy of Sciences, 2001) -
Carbon-cycle feedbacks increase the likelihood of a warmer future
(American Geophysical Union (AGU), 2007-05-04)Positive carbon-cycle feedbacks have the potential to reduce natural carbon uptake and accelerate future climate change. In this paper, we introduce a novel approach to incorporating carbon-cycle feedbacks into probabilistic ... -
The Carbon-Isotopic Composition of Proterozoic Carbonates: Riphean Successions from Northwestern Siberia (Anabar Massif, Turukhansk Uplift)
(Kline Geology Laboratory, Yale University, 1995)Thick carbonate-dominated successions in northwestern Siberia document secular variations in the C-isotopic composition of seawater through Mesoproterozoic and early Neoproterozoic (Early to early Late Riphean) time, ... -
Carbonates in Skeleton-Poor Seas: New Insights from Cambrian and Ordovician Strata of Laurentia.
(Society for Sedimentary Geology, 2010)Calcareous skeletons evolved as part of the greater Ediacaran–Cambrian diversification of marine animals. Skeletons did not become permanent, globally important sources of carbonate sediment, however, until the Ordovician ... -
Carboniferous Onychophora from Montceau‐les‐Mines, France, and onychophoran terrestrialization
(John Wiley and Sons Inc., 2016)Abstract The geological age of the onychophoran crown‐group, and when the group came onto land, have been sources of debate. Although stem‐group Onychophora have been identified from as early as the Cambrian, the sparse ... -
Carbon–Fluorine Bond Formation
(Current Drugs Ltd., 2008)We present a selection of carbon–fluorine bond formations that have been developed in the recent past. An overview of the most common fluorination reagents is followed by fluorination reactions organized by reactivity. We ... -
Carbon–Fluorine Reductive Elimination from a High–Valent Palladium Fluoride
(American Chemical Society, 2008)We have observed two high-valent arylpalladiumfluoride complexes that afford carbon−fluorine bond formation upon thermolysis. -
Carboxylic acids in clouds at a high-elevation forested site in central Virginia
(Wiley-Blackwell, 1995)During September 1990 we sampled coarse (>18-μm diameter) and fine (18- to 5.5-μm diameter) droplets and liquid-water content (LWC) in cloud from a tower on a forested ridge top in Shenandoah National Park, Virginia. ... -
Carboxylic acids in the rural continental atmosphere over the eastern United States during the Shenandoah Cloud and Photochemistry Experiment
(Wiley-Blackwell, 1995)The Shenandoah Cloud and Photochemistry Experiment (SCAPE) was conducted during September 1990 in the rural continental atmosphere at a mountain top site (1014 m) in Shenandoah National Park, Virginia. We report here the ... -
Cardiac Stem Cell Therapy and the Promise of Heart Regeneration
(Elsevier BV, 2013)Stem cell therapy for cardiac disease is an exciting but highly controversial research area. Strategies such as cell transplantation and reprogramming have demonstrated both intriguing and sobering results. Yet as clinical ... -
Cardinality Restricted Boltzmann Machines
(Massachusetts Institute of Technology Press, 2012)The Restricted Boltzmann Machine (RBM) is a popular density model that is also good for extracting features. A main source of tractability in RBM models is that, given an input, the posterior distribution over hidden ... -
Cardiovascular and Affective Recovery from Anticipatory Threat
(Elsevier, 2010)Anticipating a stressor elicits robust cardiovascular and affective responses. Despite the possibility that recovery from these responses may have implications for physical and mental well-being, little research has examined ... -
