Concentrating the dark matter in galaxy clusters through tidal stripping of baryonically compressed galactic halos
(Oxford University Press, 2010)Gravitational lensing observations of massive X-ray clusters imply a steep characteristic density profile marked by a central concentration of dark matter. The observed mass fraction within a projected radius of 150 kpc ... -
Concentration bounds for quantum states and limitations on the QAOA from polynomial approximations
(Verein zur Forderung des Open Access Publizierens in den Quantenwissenschaften, 2023-05-11) -
Concentration bounds for quantum states with finite correlation length on quantum spin lattice systems
(IOP Publishing, 2016-08-08)We consider the problem of determining the energy distribution of quantum states that satisfy exponential decay of correlation and product states, with respect to a quantum local hamiltonian on a spin lattice. For a quantum ... -
Concentrations and snow-atmosphere fluxes of reactive nitrogen at Summit, Greenland
(Wiley-Blackwell, 1999)Concentrations and fluxes of NOy (total reactive nitrogen), ozone concentrations and fluxes of sensible heat, water vapor, and momentum were measured from May 1 to July 20, 1995 at Summit, Greenland. Median NOy concentrations ... -
Concentrations and Sources of Organic Carbon Aerosol in the Free Troposphere over North America
(American Geophysical Union, 2006)Aircraft measurements of water-soluble organic carbon (WSOC) aerosol over NE North America during summer 2004 (ITCT-2K4) are simulated with a global chemical transport model (GEOS-Chem) to test our understanding of the ... -
Concentrations of trace elements in human milk: Comparisons among women in Argentina, Namibia, Poland, and the United States
(Public Library of Science (PLoS), 2017)Human milk contains essential micronutrients for growth and development during early life. Environmental pollutants, such as potentially toxic metals, can also be transferred to the infant through human milk. These elements ... -
Concept Attribution in Nonhuman Animals: Theoretical and Methodological Problems in Ascribing Complex Mental Processes
(University of Chicago Press, 1991)The demise of behaviorism has made ethologists more willing to ascribe mental states to animals. However, a methodology that can avoid the charge of excessive anthropomorphism is needed. We describe a series of experiments ... -
Concept Expansion as a Source of Empowerment
(Informa UK Limited, 2016)In the target article, Nick Haslam (this issue) explores the incidence, origins, and potential consequences of concept creep in psychology. He dedicates the majority of the article to documenting how concept creep has ... -
Conceptions of Limited Attention and Discourse Focus
(Association for Computational Linguistics/MIT, 1999)Walker (1996) presents a cache model of the operation of attention in the processing of discourse as an alternative to the focus space stack that was proposed previously by Grosz and Sidner (Grosz 1977a; Grosz and Sidner ... -
Concepts and Categories: A Cognitive Neuropsychological Perspective
(Annual Reviews, 2009)One of the most provocative and exciting issues in cognitive science is how neural specificity for semantic categories of common objects arises in the functional architecture of the brain. More than two decades of research ... -
Concepts Are More than Percepts: The Case of Action Verbs
(The Society for Neuroscience, 2008)Several regions of the posterior-lateral-temporal cortex (PLTC) are reliably recruited when participants read or listen to action verbs, relative to other word and nonword types. This PLTC activation is generally interpreted ... -
Concepts for Enhanced Energy Absorption Using Hollow Micro-Lattices
(Elsevier, 2010)We present a basic analysis that establishes the metrics affecting the energy absorbed by multilayer cellular media during irreversible compaction on either a mass or volume basis. The behaviors at low and high impulse ... -
Conceptual and institutional gaps: understanding how the WHO can become a more effective cross-sectoral collaborator
(BioMed Central, 2015)Background: Two themes consistently emerge from the broad range of academics, policymakers and opinion leaders who have proposed changes to the World Health Organization (WHO): that reform efforts are too slow, and that ... -
Conceptual distinctiveness supports detailed visual long-term memory for real-world objects
(American Psychological Association, 2010)Humans have a massive capacity to store detailed information in visual long-term memory. The present studies explored the fidelity of these visual long-term memory representations and examined how conceptual and perceptual ... -
Conceptual Object Representations in Human Anterior Temporal Cortex
(Society for Neuroscience, 2012)Interaction with everyday objects requires the representation of conceptual object properties, such as where and how an object is used. What are the neural mechanisms that support this knowledge? While research on semantic ... -
Conceptualism and Objectivity in Locke's Account of Natural Kinds
(2013-10-18)Locke's Essay Concerning Human Understanding is considered by many to be the locus classicus of a number of influential arguments for conventionalism, according to which there are no objective, privileged ways of classifying ... -
Conceptualization of Health and Social Vulnerability of Marginalized Populations During Covid-19 Using Quantitative Scoring Approach
(Informa UK Limited, 2021-02-24)Covid-19 is a global health emergency and a systemic human development crisis. Marginalized populations’ ability to respond tends to be low and associated impacts can be serious for already vulnerable communities. The virus ... -
Concerning RNA-guided gene drives for the alteration of wild populations
(eLife Sciences Publications, Ltd, 2014)Gene drives may be capable of addressing ecological problems by altering entire populations of wild organisms, but their use has remained largely theoretical due to technical constraints. Here we consider the potential for ... -
Concerted nucleophilic aromatic substitution with 19F− and 18F−
(2016)Nucleophilic aromatic substitution (SNAr) is widely used by organic chemists to functionalize aromatic molecules, and it is the most commonly used method to generate arenes that contain a 18F for use in PET imaging.1 A ... -
