Capsid Protein VP4 of Human Rhinovirus Induces Membrane Permeability by the Formation of a Size-Selective Multimeric Pore
(Public Library of Science, 2014)Non-enveloped viruses must deliver their viral genome across a cell membrane without the advantage of membrane fusion. The mechanisms used to achieve this remain poorly understood. Human rhinovirus, a frequent cause of the ... -
Captive pandas are at risk from environmental toxins
(Ecological Society of America, 2016)Ex situ conservation efforts are the last resort for many critically endangered species and captive breeding centers are thought to provide a safe environment in which to produce individuals for eventual re-introduction ... -
Capture and Modeling of Non-Linear Heterogeneous Soft Tissue
(Association for Computing Machinery, 2009)This paper introduces a data-driven representation and modeling technique for simulating non-linear heterogeneous soft tissue. It simplifies the construction of convincing deformable models by avoiding complex selection ... -
Capturing Specific Abilities as a Window into Human Individuality: The Example of Face Recognition
(Taylor & Francis, 2012)Proper characterization of each individual's unique pattern of strengths and weaknesses requires good measures of diverse abilities. Here, we advocate combining our growing understanding of neural and cognitive mechanisms ... -
Carabid beetle diversity and distribution in Boston Harbor Islands national park area (Coleoptera, Carabidae)
As part of an All Taxa Biodiversity Inventory in Boston Harbor Islands national park area, an inventory of carabid beetles on 13 islands was conducted. Intensive sampling on ten of the islands, using an assortment of passive ... -
Carbon and Sulfur Cycling below the Chemocline in a Meromictic Lake and the Identification of a Novel Taxonomic Lineage in the FCB Superphylum, Candidatus Aegiribacteria
(Frontiers Media S.A., 2016)Mahoney Lake in British Columbia is an extreme meromictic system with unusually high levels of sulfate and sulfide present in the water column. As is common in strongly stratified lakes, Mahoney Lake hosts a dense, ... -
Carbon fixation by basalt-hosted microbial communities
(Frontiers Media S.A., 2015)Oceanic crust is a massive potential habitat for microbial life on Earth, yet our understanding of this ecosystem is limited due to difficulty in access. In particular, measurements of rates of microbial activity are sparse. ... -

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

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. ...
