Reduced Specificity of Hippocampal and Posterior Ventrolateral Prefrontal Activity during Relational Retrieval in Normal Aging
(Massachusetts Institute of Technology Press (MIT Press), 2012)Neuroimaging studies of episodic memory in young adults demonstrate greater functional neural activity in ventrolateral pFC and hippocampus during retrieval of relational information as compared with item information. We ... -
Reduced Working Memory Mediates the Link between Early Institutional Rearing and Symptoms of ADHD at 12 Years
(Frontiers Media S.A., 2016)Children who are raised in institutions show severe delays across multiple domains of development and high levels of psychopathology, including attention deficit/hyperactivity disorder (ADHD). Low performance in executive ... -
Reducing Bias in Observational Studies Using Subclassification on the Propensity Score
(American Statistical Association, 2010-02-11)The propensity score is the conditional probability of assignment to a particular treatment given a vector of observed covariates. Previous theoretical arguments have shown that subclassification on the propensity score ... -
Reducing Hispanic Children's Obesity Risk Factors in the First 1000 Days of Life: A Qualitative Analysis
(Hindawi Publishing Corporation, 2015)Objectives:. Modifiable behaviors during the first 1000 days (conception age 24 months) mediate Hispanic children's obesity disparities. We aimed to examine underlying reasons for early life obesity risk factors and identify ... -
Reducing Implicit Racial Preferences: I. a Comparative Investigation of 17 Interventions.
(American Psychological Association (APA), 2014)Many methods for reducing implicit prejudice have been identified, but little is known about their relative effectiveness. We held a research contest to experimentally compare interventions for reducing the expression of ... -
Reducing noise in moving-grid codes with strongly-centroidal Lloyd mesh regularization
(Oxford University Press, 2015)A method for improving the accuracy of hydrodynamical codes that use a moving Voronoi mesh is described. Our scheme is based on a new regularization scheme that constrains the mesh to be centroidal to high precision while ... -
Reducing Stereotyping Through Mindfulness: Effects on Automatic Stereotype-Activated Behaviors
(Springer Verlag, 2008)We assessed whether mindfulness (active categorization) can prevent automatic stereotype-activated behaviors related to the elderly. Eighty participants (mean age = 24.4) were given a set of photographs to prime the dimension ... -
Reducing the Complexity Costs of 401(k) Participation Through Quick Enrollment
(University of Chicago Press, 2009)The complexity of the retirement savings decision may overwhelm employees, encouraging procrastination and reducing 401(k) enrollment rates. We study a low-cost manipulation designed to simplify the 401(k) enrollment ... -
Reduction in Learning Rates Associated with Anterograde Interference Results from Interactions between Different Timescales in Motor Adaptation
(Public Library of Science, 2010)Prior experiences can influence future actions. These experiences can not only drive adaptive changes in motor output, but they can also modulate the rate at which these adaptive changes occur. Here we studied anterograde ... -
Reduction of aberrant NF-κB signalling ameliorates Rett syndrome phenotypes in Mecp2-null mice
(Nature Publishing Group, 2016)Mutations in the transcriptional regulator Mecp2 cause the severe X-linked neurodevelopmental disorder Rett syndrome (RTT). In this study, we investigate genes that function downstream of MeCP2 in cerebral cortex circuitry, ... -
Reduction of CM elliptic curves and modular function congruences
(2005)We study congruences of the form F(j(z)) | U(p) = G(j(z)) mod p, where U(p) is the p-th Hecke operator, j is the basic modular invariant 1/q+744+196884q+... for SL2(Z), and F,G are polynomials with integer coefficients. ... -
Reduction of water evaporation in polymerase chain reaction microfluidic devices based on oscillating-flow
(AIP Publishing, 2010)Producing polymeric or hybrid microfluidic devices operating at high temperatures with reduced or no water evaporation is a challenge for many on-chip applications including polymerase chain reaction (PCR). We study sample ... -
Reductions in midlatitude upwelling-favorable winds implied by weaker large-scale Pliocene SST gradients
(Wiley-Blackwell, 2016)The early-to-mid Pliocene (3–5.3 Ma) is the most recent geologic period of significant global warmth. Proxy records of Pliocene sea surface temperature (SST) indicate significant and still unexplained warm anomalies of ... -
Reductive Coupling of CO Templated by Iron Bound to the Tris(pyrrolide)ethane Scaffold
(American Chemical Society (ACS), 2011)The reactivity of the high-spin (S = 2) [(Mestpe)Fe(THF)][Li(THF)4] (1) complex (Mestpe = tris(mesitylpyrrolide)ethane) with isocyanide and CO substrates is explored. Reaction of 1 with excess tBuNC forms a low-spin (S = ... -
Reductive degradation of perfluoroalkyl compounds with aquated electrons generated from iodide photolysis at 254 nm
(Royal Society of Chemistry (RSC), 2011)The perfluoroalkyl compounds (PFCs), perfluoroalkyl sulfonates (PFXS) and perfluoroalkyl carboxylates (PFXA) are environmentally persistent and recalcitrant towards most conventional water treatment technologies. Here, we ... -
Reductive Dissolution and Biomineralization of Iron Hydroxide Under Dynamic Flow Conditions
(American Chemical Society, 2002)Iron cycling and the associated changes in solid phase have dramatic implications for trace element mobility and bioavailability. Here we explore the formation of secondary iron phases during microbially mediated reductive ... -
Reevaluating the Arthropod Tree of Life
(Annual Reviews, 2012)Arthropods are the most diverse group of animals and have been so since the Cambrian radiation. They belong to the protostome clade Ecdysozoa, with Onychophora (velvet worms) as their most likely sister group and tardigrades ... -
Referential shift in Nicaraguan Sign Language: a transition from lexical to spatial devices
(Frontiers Media S.A., 2015)Even the simplest narratives combine multiple strands of information, integrating different characters and their actions by expressing multiple perspectives of events. We examined the emergence of referential shift devices, ... -
Referring-expression generation using a transformation-based learning approach
(Assocation for the Advancement of Artifical Intelligence, 2006)A natural language generation system must generate expressions that allow a reader to identify the entities to which they refer. This paper describes the creation of referring-expression (RE) generation models developed ... -
Refined Class Number Formulas and Kolyvagin Systems
(Compositio Mathematica, 2011)We use the theory of Kolyvagin systems to prove (most of) a refined class number formula conjectured by Darmon. We show that for every odd prime \(p\), each side of Darmon’s conjectured formula (indexed by positive integers ...
