Dynamic polarizabilities of rare-earth-metal atoms and dispersion coefficients for their interaction with helium atoms
(American Physical Society (APS), 2007)The dynamic scalar and tensor polarizabilities of the rare-earth-metal atoms are calculated with time-dependent density functional theory. The frequency-dependent polarizabilities at imaginary frequencies are used to ... -
Dynamic polymer systems with self-regulated secretion for the control of surface properties and material healing
(Nature Publishing Group, 2015)Approaches for regulated fluid secretion, which typically rely on fluid encapsulation and release from a shelled compartment, do not usually allow a fine continuous modulation of secretion, and can be difficult to adapt ... -
Dynamic Population Coding of Category Information in Inferior Temporal and Prefrontal Cortex
(American Physiological Society, 2008)Most electrophysiology studies analyze the activity of each neuron separately. While such studies have given much insight into properties of the visual system, they have also potentially overlooked important aspects of ... -
A dynamic programming algorithm for perceptually consistent stereo
(2017-09-27)This document provides details of the dynamic programming algorithm discussed in “Towards perceptually consistent stereo: a scanline study." For the motivation of the algorithm, see that paper. -
Dynamic regulation of histone lysine methylation via the ubiquitin-proteasome system.
(2013-10-18)Lysine methylation is an important post-translational modification found on histones that is added and removed by histone lysine methyltransferases and demethylases, respectively. Lysine methylation occurs in a specific ... -
Dynamic regulatory elements in single-cell multimodal data implicate key immune cell states enriched for autoimmune disease heritability
(Springer Science and Business Media LLC, 2023-11-30)In autoimmune diseases such as rheumatoid arthritis (RA), the immune system attacks host tissues1-3. Developing a precise understanding of the fine-grained cell states that mediate the genetics of autoimmunity is critical ... -
Dynamic regulatory network controlling Th17 cell differentiation
(2013)Despite their importance, the molecular circuits that control the differentiation of naïve T cells remain largely unknown. Recent studies that reconstructed regulatory networks in mammalian cells have focused on short-term ... -
Dynamic Remodeling of Dendritic Arbors in GABAergic Interneurons of Adult Visual Cortex
(Public Library of Science, 2006)Despite decades of evidence for functional plasticity in the adult brain, the role of structural plasticity in its manifestation remains unclear. To examine the extent of neuronal remodeling that occurs in the brain on a ... -
Dynamic remodeling of in-group bias during the 2008 Presidential election
(National Academy of Sciences, 2009)People often favor members of their own group, while discriminating against members of other groups. Such in-group favoritism has been shown to play an important role in human cooperation. However, in the face of changing ... -
Dynamic Reorganization of Neuronal Activity Patterns in Parietal Cortex
(2017-09-08)Neuronal representations change as associations are learned between sensory stimuli and behavioral actions. However, it is poorly understood whether representations of learned associations stabilize or continue to change ... -
Dynamic Restructuring Drives Catalytic Activity on Nanoporous Gold-Silver Alloy Catalysts
(2016)Bimetallic, nanostructured materials hold promise for improving catalyst activity and selectivity, yet little is known about the dynamic compositional and structural changes that these systems undergo during pretreatment ... -
Dynamic Rupture through a Branched Fault Configuration at Yucca Mountain, and Resulting Ground Motions
(Seismological Society of America, 2010)We seek to characterize the likelihood of multiple fault activation along a branched normal-fault system during earthquake rupture using dynamic finite element analyses. This is motivated by the normal faults in the vicinity ... -
Dynamic Scan Procedure for Detecting Rare-Variant Association Regions in Whole-Genome Sequencing Studies
(Elsevier BV, 2019-05)Large-scale whole genome sequencing (WGS) studies have enabled the analysis of rare variants (RVs) associated with complex phenotypes. Commonly used RV association tests (RVATs) have limited scope to leverage variant ... -
Dynamic Scoring: A Back-of-the-Envelope Guide
(2005)This paper uses the neoclassical growth model to examine the extent to which a tax cut pays for itself through higher economic growth. The model yields simple expressions for the steady-state feedback effect of a tax cut. ... -
Dynamic Social Choice with Evolving Preferences
(AAAI Press, 2014)Social choice theory provides insights into a variety of collective decision making settings, but nowadays some of its tenets are challenged by internet environments, which call for dynamic decision making under constantly ... -
Dynamic Spread of Happiness in a Large Social Network: Longitudinal Analysis Over 20 Years in the Framingham Heart Study
(British Medical Journal Publishing, 2008)Objectives: To evaluate whether happiness can spread from person to person and whether niches of happiness form within social networks. Design: Longitudinal social network analysis. Setting: Framingham Heart Study social ... -
Dynamic Support Culture of Murine Skeletal Muscle-Derived Stem Cells Improves Their Cardiogenic Potential In Vitro
(Hindawi Publishing Corporation, 2015)Ischemic heart disease is the main cause of death in western countries and its burden is increasing worldwide. It typically involves irreversible degeneration and loss of myocardial tissue leading to poor prognosis and ... -
Dynamic Switch of Negative Feedback Regulation in Drosophila Akt–TOR Signaling
(Public Library of Science, 2010)Akt represents a nodal point between the Insulin receptor and TOR signaling, and its activation by phosphorylation controls cell proliferation, cell size, and metabolism. The activity of Akt must be carefully balanced, as ... -
A Dynamic Theory of Nuclear Proliferation and Preventive War
(Cambridge University Press (CUP), 2016)We develop a formal model of bargaining between two states where one can invest in a program to develop nuclear weapons and the other imperfectly observes its efforts and progress over time. In the absence of a nonproliferation ...
