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 ... -

Carotid bifurcation calcium and correlation with percent stenosis of the internal carotid artery on CT angiography
(Springer Science + Business Media, 2005)The aim of this paper was to determine the correlation between calcium burden (expressed as a volume) and extent of stenosis of the origin of the internal carotid artery (ICA) by CT angiography (CTA). Previous studies have ... -
Carrier Dynamics and Absorption Properties of Gold-Hyperdoped Germanium: Insight Into Tailoring Defect Energetics
(American Physical Society (APS), 2021-06-23)Hyperdoping germanium with gold is a potential method to produce room-temperature short-wavelength-infrared radiation (SWIR; 1.4–3.0 μm) photodetection. We investigate the charge carrier dynamics, light absorption, and ... -
Cascade of electronic transitions in magic-angle twisted bilayer graphene
(Springer Science and Business Media LLC, 2020-06-11)Magic-angle twisted bilayer graphene (MATBG) exhibits a rich variety of electronic states, including correlated insulators, superconductors, and topological phases. Understanding the microscopic mechanisms responsible for ... -
Cascades in the Dynamics of Measured Foliations

Cascading Activation Across Levels of Representation in Children's Lexical Processing
(Cambridge University Press, 2010)Recent work in adult psycholinguistics has demonstrated that activation of semantic representations begins long before phonological processing is complete. This incremental propagation of information across multiple levels ... -
Cascading to the MSSM
(Springer Verlag, 2008)The MSSM can arise as an orientifold of a pyramid-like quiver in the context of intersecting D-branes. Here we consider quiver realizations of the MSSM which can emerge at the bottom of a duality cascade. We classify all ... -
