Achromatic Metasurface Lens at Telecommunication Wavelengths
(American Chemical Society, 2015) -
Acoustic buffeting by infrasound in a low vibration facility
(AIP Publishing, 2016)Measurement instruments and fabrication tools with spatial resolution on the atomic scale require facilities that mitigate the impact of vibration sources in the environment. One approach to protection from vibration in a ... -
Acquisition and Rendering of Transparent and Refractive Objects
(Association for Computing Machinery, 2002)This paper introduces a new image-based approach to capturing and modeling highly specular, transparent, or translucent objects. We have built a system for automatically acquiring high quality graphical models of objects ... -
Acritarchs and Microfossils from the Mesoproterozoic Bangemall Group, Northwestern Australia
(Paleontological Society, 1999)Three microfossil assemblages occur in the Mesoproterozoic Bangemall Group (1625-1000 Ma) of northwestern Australia, each occupying a different environmental and taphonomic setting. In peritidal environments, benthic ... -
Act Versus Impact: Conservatives and Liberals Exhibit Different Structural Emphases in Moral Judgment
(Wiley, 2017-05-31)Conservatives and liberals disagree sharply on matters of morality and public policy. We propose a novel account of the psychological basis of these differences. Specifically, we find that conservatives tend to emphasize ... -
Acting for a Reason
(Oxford University Press, 2008)Starting from the debate over whether practical reasons are mental states or the facts to which those mental states are a response, this chapter argues that being motivated by a practical reason must be a reflexive form ... -
Action Categories in Lateral Occipitotemporal Cortex Are Organized Along Sociality and Transitivity
(Society for Neuroscience, 2017)How neural specificity for distinct conceptual knowledge categories arises is central for understanding the organization of semantic memory in the human brain. Although there is a large body of research on the neural ... -
Action Embellishment: An Intention Bias in the Perception of Success
(American Psychological Association, 2011)Naïve theories of behavior hold that actions are caused by an agent’s intentions, and the subsequent success of an action is measured by the satisfaction of those intentions. But when an action is not as successful as ... -
Action Potential Initiation in the Hodgkin-Huxley Model
(Public Library of Science, 2009)A recent paper of B. Naundorf et al. described an intriguing negative correlation between variability of the onset potential at which an action potential occurs (the onset span) and the rapidity of action potential initiation ... -
Action-related properties of objects shape object representations in the ventral stream
(Elsevier (Cell Press), 2007)The principles driving the organization of the ventral object-processing stream remain unknown. Here, we show that stimulus-specific repetition suppression (RS) in one region of the ventral stream is biased according to ... -
Actions speak louder than words: An elaborated theoretical model of the social functions of self-injury and other harmful behaviors
(Elsevier BV, 2008)The question of why some people do things that are intentionally harmful to themselves continues to puzzle scientists, clinicians, and the public. Prior studies have demonstrated that one fairly extreme, direct form of ... -
Activation energy study of electron transport in high performance short wavelengths quantum cascade lasers
(The Optical Society, 2010)We present a method to study current paths through quantum cascade lasers (QCLs). The temperature dependence of the current is measured at a fixed voltage. At low temperatures we find activation energies that correspond ... -
Activation of Cdc2/cyclin B and inhibition of centrosome amplification in cells depleted of Plk1 by siRNA
(National Academy of Sciences, 2002)The events of the cell cycle, the stages at which the cell proliferates and divides, are facilitated and controlled by multiple signaling pathways. Among the many regulatory enzymes that contribute to these processes is ... -
Activation of mechanosensitive ion channel TRPV4 normalizes tumor vasculature and improves cancer therapy
(2016)Tumor vessels are characterized by abnormal morphology and hyper-permeability that together cause inefficient delivery of chemotherapeutic agents. Although VEGF has been established as a critical regulator of tumor ... -
Activation of raphe nuclei triggers rapid and distinct effects on parallel olfactory bulb output channels
(2015)The serotonergic raphe nuclei are involved in regulating brain states over time-scales of minutes and hours. We examined more rapid effects of serotonergic activation on two classes of principal neurons in the mouse olfactory ... -
Activation of the Immune Response is a Key Feature of Aging in Mice
(Springer Netherlands, 2009)The process of aging is complex involving numerous factors centered on transcriptional changes with advanced age. This study was aimed at elucidating mechanisms involved in mouse aging by conducting both gene expression ... -
The Activation Strain Tensor: Nonhydrostatic Stress Effects on Crystal-Growth Kinetics
(American Physical Society, 1991)The solid-phase epitaxial-growth rate of crystalline Si from the amorphous Si on the tensile side is greater than on the compressive side of elastically bent wafers, in marked contrast to the behavior observed under ... -
Activation Volume for Arsenic Diffusion in Germanium
(American Institute of Physics, 1996)We have measured the effect of pressure on As diffusion in Ge. Diffusion anneals on ion-implanted samples were carried out in a high-temperature diamond anvil cell using fluid argon as a clean, hydrostatic pressure medium. ... -
Activation Volume for Phosphorus Diffusion in Silicon and Si0.93Ge0.07
(American Institute of Physics, 2005)The hydrostatic pressure dependence of the diffusivity of P in compressively strained Si<sub>0.93</sub>Ge<sub>0.07</sub> and unalloyed Si has been measured. In both cases the diffusivity is almost independent of pressure, ... -
Active Avoidance Requires a Serial Basal Amygdala to Nucleus Accumbens Shell Circuit
(Society for Neuroscience, 2015)Freezing is a species-typical defensive reaction to conditioned threats. While the neural circuitry of aversive Pavlovian behavior has been extensively studied, less is known about the circuitry underlying more active ...
